Pollutants coming from automobile operation have begun to cause many environmental problems. It has been calculated, for example, that 70% of the carbon monoxide , 45% of the nitrogen oxides , and 34% of the hydrocarbon pollution in the United States can be traced directly to automobile exhausts . In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water. In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides. California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent. Which of the following is NOT true according to the text?
|
[
"Carbon monoxide can be controlled in the engine.",
"Smog will form when hydrocarbons meet nitrogen oxides in the sunlight.",
"Hydrocarbons have no poisonous character themselves.",
"The conditions that decease emission of hydrocarbons will increase emission of nitrogen oxides."

A blind baby is doubly handicapped. Not only is it unable to see, but because it cannot receive the visual stimulus from its environment that a sighted child does, it is likely to be slow in intellectual development. Now the ten-month old son of Dr. and Mrs. Dennis Daughters is the subject of an unusual psychological experiment designed to prevent a lag in the learning process. With the aid of a sonar-type electronic that he wears on his head, infant Dennis is learning to identify the people and objects in the world around him by means of echoes . The device is an improvement of the "Sonicguide", an instrument produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a smart or guide dog. As adapted for Dennis, it consists of a battery-powered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic pulse that creates an 80 degree cone of sound at 6 feet. Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch and volume with the size and distance of the object. The closer an object is, the lower the pitch, and the larger the object, the louder the signal. Hard surfaces produce a sharp ping, while soft ones send back signals with a slightly fuzzy quality. An object slightly to the right of Denny's sends back a louder sound to his right ear than to the left. Thus , by simply moving his head right and left and up and down, he can not only locate an object but also get some notion of its shape and size, thanks to the varying qualities of sounds reaching his ears as the cone of ultrasound passes _ . Dennis likes to use the device to play a kind of peek-a-boo with his mother. Standing on her knee and facing her directly, he receives a strong signal in both ears. By turning his head away, he makes her seem to disappear. "From the first time he wore it," says Mrs. Daughters, "it was like a light going on in his head." What remains to be determined is how well the device will help Dennis cope with his surroundings as he begins to walk and venture further into his environment. Meanwhile, Telesensory, Inc, is working on the development of sonar device with somewhat the same sensitivity as Dennis's for use by school-age children. What can we learn about infant Dennis' device?

Do you know that you can lose weight just by eating? If someone tells you that the only way to burn fat and lose weight is by eating like a mouse, you know it is not right. Now you can lose weight by eating the right kinds of foods in the right way! Diet pills or fiber ? Diet pills, while helping you control your appetite , come with several harmful side effects. To tell the truth, when you use them, you lose more than you gain! Here is a healthier and more natural way: increase your fiber intake. Natural fruits and vegetables are rich in fiber. These foods help keep you full for a long time so that you don't feel hungry too often. Apart from vegetables and fruits, nuts and whole grains are other foods which are rich in fiber! Soft drinks or water? If you feel thirsty, you may either drink lots of soft drinks or water. Here is an interesting fact about soft drinks: since they are rich in sugar, they not only make you fatter but also in-crease your thirst, so that you are forced to drink more of them! Not so with water! It has no unhealthy side effects! Water also cleanses your body of all harmful things and waste products, making it easier for your body to burn fat and lose weight! A large plate or a small one? We all know how important it is to eat less for the purpose of weight loss. Here is one funny thing to note: if you put very little food on a large plate, your brain will think that you have eaten less than your requirement, even though that may not be the case. However, put that same food on a smaller plate, and you will feel completely full! You may not believe it, but this is a fact. In order to feel full, you need to satisfy not only your stomach but also your eyes! Which of the following is a good way to lose weight according to the text?

The spread of Western eating habits around the world is bad for human health and the environment. These findings come from a new report in the journal Nature. David Tillman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how diet affected health. He noted a movement beginning in the 1960s. He found that as nations industrialized, population increased and earnings rose, more people began to adopt what has been called the Western diet. The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tillman says overweight people are at greater risk for non-infectious diseases like diabetes and heart disease. Unfortunately when people become industrialized, if they adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia. China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20-year period. And that is happening all across the world, in Mexico, in Nigeria and so on. And, a diet bad for human beings, is also bad for the environment. As the world's population grows, more forests and tropical areas will become farmland for crops or grasslands for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now. Mr. Tillman calls the link between diet, the environment and human health, "a trilemma": a problem offering a difficult choice. He says one possible settlement is leaving the Western diet behind. David Tilman believes that _ .

Vitamins are complex chemical substances found in many foods. The human body needs them for health and growth. The body makes some vitamins, but usually in amounts too small to meet its needs. Other vitamins are not made in the body. These must be supplied. No one knows exactly how all vitamins work. Doctors do know that vitamins have very special uses. One vitamin therefore cannot take the place of another. The steady absence of one vitamin in an otherwise complete diet causes a deficiency disease. Rickets, scurvy, and pellagra are examples of deficiency diseases. It is best to obtain vitamins by eating the foods in which they occur. There are also pills that contain a single vitamin or a combination of vitamins people should consult their doctors before they take any vitamin pills. Scientists have discovered about 25 vitamins and their different forms that are very important to human beings and other forms of life. Experts believe that there are many more vitamins to be discovered. There are two basic groups of vitamins. One group of vitamins dissolves in fat and is therefore called the "fat-soluble" group. Vitamins A, D, E and K are in this group. The other group is known as "water-soluble" vitamins. These vitamins, understandably, dissolve in water. Among this group are Vitamin C and the B group of vitamins. Vitamin A aids the building and growth of body cells. This vitamin is therefore vital for the growth of children and for good development of babies before birth. Vitamin A is also important for good vision at night. Vitamin B1 is also called thiamine. This vitamin prevents and cures disease. Vitamin B2, called riboflavin, is needed for growth, healthy skin, and for the eyes. Vitamin C, or ascorbic acid, prevents and cures scurvy. Vitamin D is a group of 10 vitamins that prevents rickets. Scientist believe that Vitamin D3 forms in the skin when the body is exposed to sunlight. Because of this, it is called the "sunshine vitamin". A lack of Vitamin D may lead to bone damage; too much may cause kidney disease. All of the functions of Vitamin E, also called tocopherol, are not known. It is necessary for reproduction in animals. Vitamin K is necessary for making the blood clot. The more that is learned about vitamins, the more it is realized how these chemical substances play a part in all aspects of human activity. Which of the following statements is true?
|
[
"The human body can produce enough vitamins for itself.",
"Until now, scientists have discovered all the vitamins we need.",
"People should take more vitamins.",
"Each kind of vitamin plays a special role in human body."

As a boy,Tim was much influenced by books about the sea, but in fact by the age of fifteen he had decided to become a doctor rather than a sailor. His father was a dentist and as a result Tim had the opportunity of meeting many doctors either at home or elsewhere. When he was fourteen he was already hanging around the clinic of a local doctor where he was supposed to be helping to wrap up medicine bottles,but was actually trying to listen to the conversations taking place between the doctor and his patients in the next room. During the war Tim served in the Navy as a surgeon ."That was the happiest time of my life. I was dealing with very real suffering and on the whole making a success of it ."In California he taught the country people simple facts about medicine. He saw himself as a life-saver. He had proved his skills to himself and his ability to take decisions. Thus,while he was able to tell them what to do, he could feel he was serving them. After the war, he got married and chose to be a doctor in the countryside,working under an old doctor who was popular in the area,but who hated the sight of blood and believed that the secret of medicine was faith. This gave the younger man many opportunities to go on working as a life -saver. Tim decided to become a doctor at fifteen mainly because

When doctors urge overweight kids to pick up more activities,reading probably isn't what they have in mind. Yet a new study by fatness researchers at Duke University finds that the simple act of reading--depending on the choice of material--can cause weight loss in teenage girls. The study's experimental group included 31 fat girls aged 9 to 13,who took part in the Healthy Lifestyles Program at Duke Children's Hospital. The girls read a novel called Lake Rescue,whose protagonist is an overweight teenager who struggles with low selfesteem,feelings of loneliness and teasing because of her size. A group of 33 girls read a different book called Charlotte in Paris,which did not have an overweight character,and another group of 17 girls read neither book. At the end of the sixmonth experiment,all the girls who read books had lost weight,but the girls who read Lake Rescue lost more. They lowered their body mass index (BMI) by 0.71,compared with 0.33 in the Charlotte group,an average 0.05 increase among the nonreaders. The idea behind the study,says Dr Sarah Armstrong,director of Healthy Lifestyles,was to find a way to encourage the girls without adopting the restrictive and often authoritative voice of so many other nutrition and diet programs. Lake Rescue was the perfect instrument,says Armstrong;it presents a likable character to whom the girls could relate and whom they could learn from. As the book progresses,its protagonist learns to make healthier lifestyle choices and finds an adviser to help keep her on track. Armstrong says," _ learns that she can become healthier,and the 'I can do it' feeling resonates with the teenage girls." In which part of a newspaper can we read the above passage?

Four hundred and three babies are crying loudly. Do you know how to make them quiet in 41 seconds? There is an amazing new product on sale in prefix = st1 /Japanwhich does exactly this. It is an LP (a long-playing record) of sounds from inside a mother's body, which a hospital doctor recorded. In tests with the record she played the LP to 403 crying babies. After 41 seconds not one baby was crying and 161 of them were sleeping. The record began as an experiment by Professor Hajime Minooka of the Nippon Medical University near Tokyo. He was looking for something natural that helped new-born babies go to sleep. The sound of the mothers' heart-beat and other body sounds are the things the babies heard inside their mothers. They feel safe and happy when they hear these sounds again. And they go to sleep. Hospitals in Osaka and Tokyoare using the LP. 10, 000 young couples are using it too. Toshiba Music Company who makes and sells the records is very happy. One and a half million couples marry every year inJapan. Many will have babies, so the LP will definitely be a hit!

A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.

It would be interesting to discover how many young people go to university without any clear idea of what they are going to do afterwards. If one considers the enormous variety of courses offered, it is not hard to see how difficult it is to select the course most suited to his interests and abilities. If a student goes to acquire a broader perspective of life, to enlarge his ideas and to learn to think for himself, he will undoubtedly benefit, since school often has too restricting an atmosphere, with its timetables and disciplines, to allow him much time for independent assessment of the work he is asked to do. Most students would, I believe, profit by a year or so's exploration of different academic studies, especially those "all-rounders" with no particular bent. They should have longer time to decide in what subject they want to take their degree, so that in later life they do not look back and say, "I should like to have been an archaeologist. If I hadn't taken a degree in Modern Languages, I shouldn't have ended up as an interpreter, but it's too late now. I couldn't go back and begin all over again, even if I had the chance." There is, of course, another side to the question of how to make the best use of one's time at university. This is the case of the student who excels in a particular branch of learning, is a first-rate mathematician, scientist, linguist and what you have. He is immediately accepted by the university of his choice, and spends his three or four years becoming a specialist, emerging with a first-class Honors Degree and very little knowledge of what the rest of the world is all about. It therefore becomes more and more important that, if students are not to waste their opportunities and, incidentally, the taxpayers' money, there will have to be much more detailed information about courses, more advice from Career Masters and Course Tutors if _ are not to bring up, on one hand, a band of specialists ignorant of anything outside their own subject, and on the other hand, an ever-increasing number of graduates qualified in subjects for which there is little or no demand in the working world.

Scientists in Israel have discovered a new way to test for water pollution by "listening" to what the plants growing in water have to say. By shining a laser beam on the tiny pieces of _ floating in the water,the researchers said they hear sound waves that tell them the type and amount of contamination in the water. "It is a red light,telling us that something is beginning to go wrong with the quality of water," said Zvy Dubinsky,an aquatic biologist at Israel's Bar Ilan University."Algae is the first thing to be affected by a change in water quality.""The secret," he said,"is to measure the rate of photosynthesis in the algae,meaning the plant's ability to transform light into energy." During photosynthesis,plants also release oxygen into the air. Dubinsky's technique is easy to perform because of the overabundance of algae in the planet's water.Most of the oxygen in the atmosphere comes from algae.A prototype tester that occupies about one square meter of a laboratory desktop,shoots a laser beam at water samples to stimulate photosynthesis in the algae.But not all of the laser's heat is used.Depending on the condition of the algae and the rate of photosynthesis,some of the heat is shot back into the water,creating sound waves,Dubinsky said.With a special underwater microphone,researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water. "Algae suffering from lead poisoning,like waste discharged from battery and paint manufacturing plants,will produce a different sound than those suffering from lack of iron or exposure to other toxins," said researcher Yulia Pinchasov.She said that testing algae photosynthesis can determine water quality more accurately and easily than laborintensive methods now used like chemical and radioactive carbon testing. Why is the algae tested?

In many sports, physical contact is part of the game. But when athletes hit their heads, the hit can cause concussions . Concussions have long been a concern for professional athletes, but they've become more common among young players too. Between 2001 and 2009, the number of kids under 19 visiting doctors for concussions each year increased by 62 percent. Engineers are developing new helmets , and new rules are limiting physical contact in some sports. But are these efforts enough to protect kids' brains? Concussions can happen during many types of activities. But sports like football and soccer are especially risky. When you run or jump, your body is moving at an increased speed. A sudden hit causes you to move faster in a different direction. "It's like when you're in a bus and it makes a sudden stop," says Dr. Kevin Crutchfield, an expert at a sports concussion center in Baltimore, Maryland. "You hit the inside of the bus." This hit damages the brain. It affects the way the brain functions. So some sports require athletes to wear helmets. Helmets help reduce the force of a hit. The hard outer shell spreads the force of larger area. Inside a helmet, a plastic or air-filled lining also helps soften the blow. Steve Rowson is an engineer at Virginia Tech. In his lab, he tests how helmets hold up against different types of hits. No helmet can prevent concussions completely, says Rowson. But he's found that when wearing a newer football helmet, the player's head doesn't gain speed as much after a hit. That lowers the risk of concussions. Many youth sports teams have set limits on physical contact to reduce the risk of concussions. In soccer, most concussions happen as a result of headers--shots or passes made with the head. That's why many people think kids shouldn't head the ball until high school. These efforts should help, says Crutchfield. But the best way to prevent long-term brain injuries, he says, is to stop playing immediately if you suffer concussion. "Protect yourself today so you can play again tomorrow."

As they migrate , butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind. Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights. To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes. Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate . Many migrating birds do the same thing. The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops. It is not easy to study the migrating behavior of the insects because _ .

Ma Yan is not really a writer, but this 15-year-old girl has written a book that has moved many people around the world. Ma Yan's diary tells us about Ma's life. She lives in a poor village called Zhangjiashu in Tongxin, Ningxia, and she has no money to go to school. However, she is brave and wants to go to school very much. Her mother gave her diary to a reporter, Pierre Haski when he went to Zhangjiashu in 2001. Now, Ma Yan's diary has been published in France, Italy, Germany, Japan and China. Ma Yan is now a Junior Three student at Yuwang Middle School in Tongxin. Before this, she had to drop out of school twice. She had to stop going to school the first time, because her mum told her there was no money for her to go to school. She worked for 21 days and saved 13 yuan. With this money, she went back to school. The second time, her family told her she had to leave school while her two brothers could stay. "I want to study," Ma Yan wrote in her diary. "Why can boys study but girls can't? It would be wonderful if I could stay at school forever." Ma Yan loves school so much because she wants to have a better life. "My parents work hard in the fields but they are still poor. They have no knowledge . Most girls in my village leave school early and get married young. I don't want that kind of life," Ma Yan said. After her story became known, many students sent money to her. She hopes to go to Tsinghua University and become a reporter. "Then, I can find poor kids like me, and help them," she said. Ma Yan wants to study because she wants to _ .

Are you feeling blue? An American study suggests that being surrounded by happy friends and neighbours could have more of an effect on your happiness than money.That is the finding of researchers from Harvard University and the University of California at San Diego. Nicholas Christakis and James Fowler studied the emotional health of more than 4,700 people.They used information from the Framingham Heart Study.That study began sixty years ago in the American community of Framingham.Massachusetts.It was started to learn more about the risks of heart attack and stroke. For the new study,the researchers examined the emotions of the men and women in the Framingham Heart Study.The information was gathered from 1983 to 2003. The researchers found that friends of happy people had a greater chance of being happy themselves.That means that happiness spreads,or has a contagious effect,among people.And,the smaller the physical distance between friends,the larger the effect they had on each other's happiness. Sadness was also contagious among friends,but not as much as happiness.The researchers say social groups did not influence happiness as much as personal situations. However,people removed by as much as three degrees of separation still had an effect on one's happiness.The expression three degrees of separation means the friends of an individual's friends. In fact,persons with three degrees of separation had a greater effect on an individual's happiness than having five thousand dollars.The researchers say the study is historic because it shows that social effects on health can be spread among people. Another finding is that people who work together or are married do not have as much of an effect on happiness levels as friends.The researchers say this is often true among friends of the same sex. The report is about_.

The planets aren't the only wanderers of the sky. There're some things even farther and longer. Long after people were no longer afraid of planets, they still thought the comets were bad objects that traveled in the sky. They were afraid that the comets would suddenly land on the earth and hurt them. But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless thing. Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That's why they're called comets. Comet means long-haired. Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet's head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn't the great big thing hurt us if it hit the earth? Because it isn't solid. It's thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth. Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again. Perhaps these comets that never return have broken into pieces. For some _ think that shooting stars are pieces of broken comets. People were afraid _ .

True to their reputation as leisure-loving gourmets ,the French spend more time sleeping and eating than anyone else among the world's wealthy nations,according to a study published on Monday. The average French person sleeps almost nine hours every night,more than an hour longer than Japanese and Korean,who sleep the least in a survey of 18 members of the Organization for Economic Cooperation and Development (OECD).Despite their siesta habit,Spaniards rank only third in the poll after Americans,who sleep more than 8.5 hours. And while more and more French people grab a bite at fast-food chains these days or,wolf down a sandwich at their desk,they still spend more than two hour's a day eating. That means their meals are twice as long as those of the average Mexican,who dedicates just over an hour a day to food,the OECD's "Society at a Glance" report on work,health and leisure in Asia,Europe and North and South America found.The Japanese,scrimping on sleep and burdened with long working hours,still manage to spend close to two hours a day eating and drinking,placing them third behind New Zealanders. Despite the limited amount of time Americans spend eating each day---about an hour and a quarter--U.S.obesity) rates are the highest in the 30 members of OECD. The Japanese like to spend what remains of their rare free time watching television or listening to the radio.This takes up 47 percent of leisure time in Japan.Norwegians spend the most time at leisure,just over a quarter of their day,while at the low end,Mexicans spend just 16 percent of their time having fun. The OECD has 30 members.The survey covers only the countries for which appropriate figures were available. As to eating time,the CORRECT order is _ .

Wake Up,Sleep Gene Some people can stay up all night and still get work done the next day.I'm not one of them.After a night without enough sleep,I feel bad-tempered.I have trouble remembering things.And all I want to do is crawl back into bed and sleep. How do you feel after you've stayed up late to finish schoolwork? Or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes. New research suggests that a gene called period 3 affects how well you function without sleep.The period 3 gene comes in two forms: short and long.Everyone has two copies of the gene.So,you may have two longs,two shorts,or one of each.Your particular combination depends on what your parents passed on to you. Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of period 3.Study participants had to stay awake for 40 hours straight.Then,they took tests that measured how quickly they pushed a button when number flashed on a screen and how well they could remember lists of numbers. Results showed that the people with the short form of period 3 performed much better on these tests than the people with the long form did.In both groups,people performed worst in the early morning.That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating. After the first round of experiments,participants were finally allowed to sleep.People in the group that performed well on the tests took about 18 minutes to nod off. People with the long period 3 genes,by contrast,fell asleep in just 8 minutes.They also spent more time in dip sleep.That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form. I think I must have the long form of period 3.What about you? If one lacks enough sleep,one should avoid doing important or dangerous things _ .

Most parents of kids under age 8 don't worry about how much time they spend watching TV or using other media, from computers to smart phones to tablets PCs, according to a new survey that found a child's use of media often reflects how much time parents spend in the similar way. We generally found that media use is not a source of conflict in the home" for families with young children, Ellen Wartella, a researcher from Northwestem University, told USA Today. She led a survey of 2,326 parents who have children 8 and younger.It found that in 80 percent of families, children's media use was not a problem, with 55 percent "not too" or" not at all" concerned about it. It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity.The exception is video games, which are viewed more negatively than TV, computers or mobile devices."Parents rated video games as more likely to have a negative effect on children's school performance, attention time, creativity, social skills, behavior and sleep than any other medium," the researchers said in a news conference about the survey. The findings exposes a generational shift in parental attitudes about technology's role in young children's lives," said Wartella."Today's parents grew up with technology as a central pact of their lives, so they think about it differently than earlier generations of parents, instead of a battle with kids on one side and parents on the other, the use of media and technology has become a family affair. " The researchers identified three media environments created by parents: media-centric (39 percent of families) , media-moderate (45%)and media-light (16%). Children in media-centric families spend at least three hours more each day watching TV or using computers, video games and tablet PCs don't make parenting easier.And 88 percent of parents say they are most likely to turn to toys or activities to keep their children occupied.Slightly fewer turn to books (79%) and TV(78%). The survey didn't look at how media affects children. That's a topic that the American Academy of Pediatrics has handled a number of times. The AAP says studies have found too much media use can lead to attention- problems, school difficulties, sleep and eating disorders and being fat. In addition, the Internet and cell phones can provide platforms for illegal and risky behaviors. By limiting screen time and offering educational media and non-electronic formats such as books, newspapers and board games, and watching television with their children, parents can help guide their children's media experience. Putting questionable content into context and teaching kids a700ut advertising contributes to their media literacy ," it says. The pediatricians' group says parents should have "screen-free zones" and TV should be turned off during dinner. At most, it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content. It is important for kids to spend time on outdoor play, reading, hobbies and using their imaginations in free play." Kids under 2 should not use television and other entertainment media because their brains are developing quickly and they learn best from direct human interaction," the group says. An article on screen time by t.he Mayo Clinic also notes problems linked t.o over screen time, including being fat, irregular sleep , behavioral problems , weak school performance , violence and less time for active and creative play. Which of the following is a suggestion by the researchers?

Science can't explain the power of pets,but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack,reduce loneliness and spread all-round good cheer. Any owner will tell you how much joy a pet brings.For some.an animal provides more comfort than a husband/wife.A 2002 study by Karen Allen of the State University of New York measured stress 1evels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic or held a hand in ice water.Subjects completed the tasks alone,with a husband/wife,a close friend or with a pet.People with pets did it best.Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates.With pets in the room,people also made fewer math mistakes than when doing in front of other companions.It seems people feel more relaxed around pets,says Allen,who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds,or 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15%of their body weight.Dog owners didn't lose any more weight than those without dogs but,say researchers,got more exercise overall-mostly with their dogs--and found it worth doing.

Most people are aware that outdoor air pollution can damage their health,but many do not know that indoor air pollution can also have significant health effects.Environmental Protection Agency studies indicate that indoor levels of pollutants may be 3~5 times,and occasionally more than 100 times,higher than outdoor levels.These levels of indoor air pollutants may be of particular concern because most people spend about 90% of their time indoors. There are many sources of indoor air pollution in any home.These include sources such as oil,gas,coal,wood,and tobacco products,building materials,wet or damp carpet,and furniture made of certain pressed wood products,products for household cleaning and maintenance,personal care,or hobbies,central heating and cooling systems. Immediate effects may show up after a single exposure or repeated exposures.These include _ of the eyes,nose,and throat,headaches,dizziness.Such immediate effects are usually shortterm and treatable.Sometimes the treatment is simply removing the person's exposure to the source of the pollution,if it can be identified. The likelihood of immediate reactions to indoor air pollutants depends on several factors.Age and preexisting medical conditions are two important influences.In other cases,whether a person reacts to a pollutant depends on individual sensitivity,which varies tremendously from person to person.Some people can become sensitized to biological pollutants after repeated exposures,and it appears that some people can become sensitized to chemical pollutants as well. Certain immediate effects are similar to those from colds or other viral diseases,so it is often difficult to determine if the symptoms are a result of exposure to indoor air pollution.While pollutants commonly found in indoor air are responsible for many harmful effects,there is considerable uncertainty about what concentrations or periods of exposure are necessary to produce specific health problems.People also react very differently to exposure to indoor air pollutants.Therefore,further research is needed to better understand the effects of indoor air pollution and to find efficient ways to protect our health. According to the author,which may NOT be the source of indoor air pollution?

Skipping classes, particularly big lectures where an absence is likely to go undetected, is a tradition among college undergraduates. These days, however, some professors say they're seeing more _ , as students make the most of new technologies as learning aids. Americ Azevedo taught an "Introduction to Computers" at the University of California, Berkeley, US last semester. By visiting the course's website, the 200 enrolled students could download audio recordings or watch digital videos of the lectures, as well as read the instructor's detailed lecture notes. But there was one big problem: So many of the undergraduates relied on the technology that at times only 20 or so actually showed up for class. Doug Suda, 19, a student in Azevedo's class last semester, said he skipped about three-quarter of the lectures. It's largely because he was busy with an off-campus job and was taking the course to fulfill a business major requirement. At the end of the term, Suda prepared hurriedly for the final exam by watching videos of about 15 lectures over three days. "If I hadn't that... I would probably fail the class," said Suda, who instead received a B-plus. Despite the concerns about absenteeism, schools are increasingly experimenting with ways to let students watch or listen to lectures on their computers or digital music players, like iPods. Last month, Harvard Medical School began "Podcasting" lectures. Students can download them into digital musical players, and study while they, say, go for a walk. As many academics accept the electronic innovation, others are pushing back. To encourage attendance, they are applying low-tech tactics, like giving more surprising quizzes or cutting back their online offerings. Lee Chanian, a UCLA economics professor, says "too much technology leads to passive learning environment and encourage more absenteeism". He now puts fewer lecture materials online, and provides extensive notes only for the most complicated topics. What could be the best title for this passage?

Chinese scientists have found a new way to use cells found in human urine that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells. The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders. Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial cells in urine into NPCs. These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said. "These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient". Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said. Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases." "It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies. Pei and his tean try their best to work hard in order to _ .

One of the 10 things that happy families do is to eat dinner together. As growing up, I thought everyone ate dinner as a family. However, now I realized that is not the case. In fact, most families eat dinner together only about four times a week and 10% of families only eat together twice a week. And as children get older and the number of activities they are involved in increases, the meals eaten as a family decrease. Studies show that families who eat dinner together benefits in a variety of ways. Eating together helps families achieve better communication, children do better in school and are better adjusted, and the entire family enjoys better nutrition . Increased Communication Eating dinner together as a family provides opportunities for communication. A "Family Dinner Experiment " conducted by Oprah Winfrey in 1993 challenged five families to eat dinner together every night for a month for at least half an hour. At first the families found it difficult but by the end of the study they wanted to continue eating dinner together. The biggest surprise for the parents was "How much their children treasured the dependence time with their parents at the table." Superior Academic Performance Family meals also help improve school performance. A 1994 survey by Louis Harris and Associates had 2000 seniors take an academic test and answer a list of personal questions. Researchers found that "Students who regularly ate dinner with their families four or more times a week scored better than those who ate family dinners three or fewer times a week. These results crossed racial lines and were a greater indicator than whether the child was in a one or two-parent family." Better Adjusted A study by Drs. Bowden and Zeisz found that "the teens who were best adjusted ate a meal with an adult in their family at an average of 5.4 days a week, compared to 3.3 days for teens who didn't show good adjustment." The well-adjusted teens were "less likely to do drugs or be depressed and were more motivated at school and had better relationships." Dr. Bowen said, "that mealtimes were a sort of 'marker' for other positive family attributes and seemed to play an important role in helping teens deal well with the stresses of adolescence ." According to the "Family Dinner Experiment" in 1993, what surprised the parents was that _ .

A team of researchers from Oxford University has demonstrated a self-driving car that is different from such cars being tested by Audi, Ford, etc. It' s much cheaper because it's based on off-the-shelf technology and controlled by an ordinary iPad. Instead of using GPS to understand the location, the car learns routes when a person is driving, and then asks after it's got it down, if the driver would like the computer to take over. As time passes, it's becoming very clear that people believe computers would be better drivers than humans. This has been proven by extensive research that indicates that computers are able to react more quickly to driving conditions, make smarter decisions, don't take risks, and don't make mistakes in concentration. They don't drink either, of course, which means accidents due to drunk driving could be reduced dramatically if the computer could take over when someone needs to get home from the bar. And the team says drivers don't need their cars to know everything about every road, condition or possible danger. Instead, they just need to know how to get from one point to another, and to do a good job of it when asked. To that end, the researchers have added cameras, lasers, a central computer to process information and a regular iPad. In practice, the car would learn how to get to and from places that the driver frequents, such as their work place, the local pub or grocery store. Once it has it down, the computer asks the driver if they' d like a rest. If so, they simply tap the iPad, and the car takes over. It' s very simple and doesn't require nearly the same number of devices as those being tested by other car companies. The researchers say people might be able to get the total price of the system below a hundred dollars. And of course, the iPad can be lifted out and carried away for other purposes when not being used as a driver assistant. The car tested by Oxford University are different from others in that they _ .

Instead , they use palm size , or specially--designed computers. The teacher downloads texts from Internet libraries and sends them to every student's personal computer. Having computers also means that students use the Web. They can look up information on any subject they're studying from maths to social science. High school teacher Judy Herrell in Florida, US, described how her class used the Web to learn about the war in Afghanistan over one year ago. We could touch every side of the country through different sites from the forest to refugee camps, she said ."Using a book that's three or four years old is impossible."And exams can go on line too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book. A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie--Sorrell in Kentucky,US, said she used to give about 900 pieces of paper each week to each student. "Think about the money and trees we could save with the computers,"she said .But, with all this technology, there is always the risk that the machines will break down. So , in case of a power failure or technical problems, paper textbooks are still widely available for these hi--tech students. The high school teacher, Judy Herrell, used the example of her class to show that _ .

Science, as we think, was born when the Greek philosopher ( ) Thales ( about 640-546 B.C.) asked a difficult question: What makes up our universe? No one had a ready answer, so Thales went on studying the earth around him, the sky and the stars. He saw so much water on earth and so much water falling from the sky as rain that he decided water must be the basic substance ( ) of the universe. Other Greek thinkers became interested in this question. They suggested other answers. One said that because air lies around the earth, it must be air that makes up all things. Another said that fire, appearing in different forms, was the building block of the universe. The Greek philosophers were feeling their way towards the ideas on which chemistry is based. Centuries later, scientists proved that the universe is made up of certain basic substances. But the list is much more _ than the Greeks realized. We now know of 103 basic substances which we call " elements ( )". Thales, the famous Greek philosopher, died when he was about _ .

Have you ever looked toward the sky on a fall day and witnessed a group of migrating birds? If so, you probably noted the V-shaped formation of the birds or the birds flying in a ball-like formation. Why do birds fly this way? Many theories have been developed to explain the formation patterns of different types of birds. One theory is that birds fly in certain formations to take advantage of the laws of nature. The birds know that flying in a V-shaped pattern will save energy. Like the lead cyclist in a race who decreases wind force for the cyclists who follow, the lead bird cuts wind force for the birds that follow. This decrease in wind force means that the birds use up to 70 percent less energy during their flight. When the lead bird becomes tired, a more rested bird takes over that position. But saving energy is important for more than one reason. Sometimes food is short during migration flights. Keeping energy enables the birds to fly longer distances between meals. When food is sighted, the birds guide one another in a different way. When a bird identifies a familiar feeding area, it might turn around in order to signal the group to change direction. Then, this bird becomes the new leader. It helps guarantee that other birds will know exactly where it is going. Then the whole group makes a change in direction, gently streaming from the sky down to the ground. This formation is like an arrow pointing to the location of food. Scientists have also studied the birds that sometimes fly in a ball-like formation. Researchers believe that the birds come together if a predator is spotted. The predator may then become impatient waiting for a single bird to fly away from the group. The birds will often dip and dive as a group, frustrating even the most persistent enemy. Scientists report that this is a very effective method of defense against an attack. The birds care for their fellow fliers through teamwork. As transportation expert Henry Ford once said, "If everyone is moving forward together, then success takes care of itself." When it comes to teamwork, these feathered fliers are a soaring success! According to the passage, we can learn that birds _ .

Students at New Market Elementary School had a fitter lifestyle last week. About 50 students participated in a 30-minute workout after school on Friday in the school's gym. This was a Fit Fridays program introduced at the school by Families Plus, a non-profit group that provides programs to enrich the lives of families and children in Frederick County. The free program aims to encourage students from kindergarten through fifth grade to be physically active by having them participate in various age-appropriate activities designed to promote a love of exercise, according to Kim Ragan, head of the program. The program, which started at the school on Nov.9, 2012, has since become a hit, Ragan said. Emily Liston, 37, said the program allows students to focus on fitness as a priority in their lives. "There're so many things to stop them from being active," she said. "So, anything to keep them moving is good, especially in the winter months". Jennifer Mitchell, 40, whose daughter Alexandra, 7, participated in the Fit Fridays program, said that learning the importance of being active isn't the only thing students are learning from the new program. "It's a great opportunity for them to get some exercise and also to learn to get along and socialize, to learn teamwork," she said. "In school they have to do activities like this but they want to do it." Riley Glynn, 9, a fourth grader at the school, said his favorite part of the program is getting to spend more time with his friends. "It's fun to play with people," Riley said. "It's like physical education after school but it really helps you." "You learn how to make yourself stronger," said Megan Hummel, 7, a first grader. Ragan said she plans to expand the program to include other schools in the county, but she has been having trouble finding fitness instructors to participate. "As soon as I can get instructors to teach we'll expand," she said. Jennifer's words show that the program _ .

Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest. Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes . To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees. In some parts of the world, populations of big trees are dwindling because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear. Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. "During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic rate increases," explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth. The darks' theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions. Besides, big trees face threats from elsewhere. According to the passage, big trees make great contributions to the ecosystem because _ .

"In the old days," as one wife said. " The husband was the husband and the wife was the wife." In the past husbands each had their own way of going on. The wives' jobs were to look after them. "The wives wouldn't stand for it nowadays. Husbands help with the children now. They stay more, as well as have more interest, at home." We shall give some examples of what husbands do, firstly in sharing work with their wives; and secondly, in their largely independent domain of house repairs. "Some husbands, as well as doing much of the heavy work in the home, carrying the coals, and emptying the rubbish, act as assistants to their wives for at least part of the day." Mr. Hammond washes up the dishes every night and lays the breakfast for the morning. Mr. Clark said that on Sunday mornings he usually hovered around and read plays aloud for his wife while she did a bit of washing.

When I got up, Mom was already awake. I could hear her doing something in the kitchen. It's was my birthday, and I was afraid. What if my husband had neglected to take Mom shopping for a card? Once Mom found it was my birthday, she would be sad that she had forgotten and had nothing to give me. She even can't remember what we did two hours ago because of dementia . Birthdays are not a big deal to me. I hate growing older. I don't mind if Mom forgets my birthday as long as she still remembers me. That someday she might not recognize me has been my biggest fear ever since Mom got dementia. I can't imagine anything more devastating than being forgotten by my own mother. When Mom was diagnosed with vascular dementia seven years ago, I was told she did not have Alzheimer's disease . I hoped that meant she would never forget her family. But as Mom's dementia progressed, I realized that I had no idea whether vascular dementia could be as bad as Alzheimer's. I really didn't understand the difference. The sleeping house was quiet except for the sound of Mom washing the bowls left last night in the kitchen. Will Mom live long enough to forget me? Will the day come when she no longer worries about remembering my birthday because she no longer knows that I exist? In the kitchen, Mom heard me come near. She hurried to the door, face ringing with smiles. "Happy birthday to you," she sang. We laughed as I hugged her tightly, and both of us were very surprised that she had remembered. Moments later she said, "Oh, there seems to be something here for you." She brought me her card. My husband did, after all, take her shopping. The birthday-for-a-daughter card was filled with expressions of love in pink. How did the writer feel about Mom's dementia? _ .

Saturday, March 20, 2010 Dear Mom and Dad, The time has come: I'm graduating, and I thank you both for all your help during these 15 years. I still remember when you used to say, "You can be whatever you want". I'm so glad you are my parents, especially when I hear kids say they don't get on well with theirs. I'm glad that you support me when I decide to do anything. You always try to help, and that's important to me. Dad, I remember when you first took me fishing. I loved going even though I never caught anything. I also remember when you would get angry with me. I realize you were only trying to show me the right way. When I would cry, you would always be there to try to cheer me up. That's what I call a good, loving, caring dad. Sometimes you and Mom don't agree with me, but you are there by my side in anything that I do, and that's why I love you both so much. Mom, I enjoy going out with you and having our happy time every Friday night, and I hope that never changes. I love telling you everything; the best part about you is that you listen. I'm glad we do a lot together. You love to have fun, and _ You always give me your opinion and I listen. Thank you for bringing me up. Love always, Allison What makes Allison and her mother good friends?

Many of us know that fast food is not good for us: it makes us fat and has twice the amount of salt an adult should eat. Moreover, you may not be aware that fast food may have a subliminal effect on behavior, making people impatient even when they are not short of time, according to a new study published in the journal Psychological Science. "The unconscious goal of saving time embedded in fast food may have the unexpected consequence of inducing haste and impatience," the researchers claim. More strikingly, they found that the mere exposure to fast food symbols "reduced people's willingness to save and led them to prefer immediate gain over greater future return". In the study, student volunteers were shown in rapid succession logos from fast-food chains including McDonald's, Burger King, KFC and Subway. Participants preferred time-saving products like three-in-one skincare treatments rather than separate versions after seeing the logos. When asked whether they would accept a small sum of money immediately or a larger amount in a week's time, they again chose an instant reward after being exposed to the brands. "Fast food represents a culture of time efficiency and instant gratification ," said researcher Sanford DeVoe, professor of organizational behavior at Canada's Toronto University. "It is promoting a general sense of haste whether time is a relevant factor in the context or not." Judging from the article, which of the following statements is FALSE?

The life-long benefits of teaching children good money habits make it well worth the effort. Children who are not taught these lessons pay the consequences for a life time. Some parents don't teach children about money because they think they shouldn't talk about money with children, don't have the time, or think they don't have enough money. Parents should take the time to teach children about money regardless of their income and should start when children are young. Most people have strong feelings and opinions about money, based on childhood experiences and the values and beliefs of their families. Most often, these experiences, values, and beliefs are different for each parent. It is important for the healthy development of children that parents talk about these feelings and opinions and establish a consistent approach to teaching children about money. Here are some guidelines parents can keep in mind as they begin the financial socialization of their children: Advise rather than order how the child's money should be used. Allow children to learn by mistakes and by successes. Be consistent while taking children's differences into account. Include all family members in money management discussions, decision making, and activities suitable for their age. Explan to children what they can and cannot do and the consequences of going above the limits. As children get older increasingly include them in discussions of limits and consequences. Expect all family members to perform unpaid, routine household work based on their abilities. Express your desire to have things you can't afford. Children need to know that parents say "no" to themselves, too. The writer believes that if children don't learn good money habits, they _ .

Scientists are debating how to limit their newly-discovered power to change genetic structure. Scientists already modify the genes of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes that carry the Zika virus. They might also be able to permanently remove species of plants and animals that are destructive to other species. In a report published last week, the U. S. National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released into the wild. Sixteen biologists, ethicists and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms from the laboratory into nature. Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction . Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country's borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet. What can be the best title for the passage?

Most teenagers in Britain receive pocket money from their parents. A report by the Bank of Scotland interviewed over 1,000 young people in Britain and found that 77% get pocket money. Different families give different amounts of pocket money. The average for eight-to-fifteen-year-olds in the UK is about PS6 a week. Children in Scotland receive slightly more than the national average and Londoners get the most. Teenagers, logically, get more money than younger children. Some fifteen-to-nineteen-year-olds receive more than PS100 a month. The report found that many children save at least a quarter of their weekly pocket money and that more boys than girls save their money. Lots of young people have to do housework to get their pocket money. They help at home with jobs like cleaning and cooking. A part-time job is a choice for teenagers who don't have pocket money or who want to earn extra money. About 15% of teenagers have a job. Popular part-time jobs for teenagers include delivering newspapers, shop work, and working in a restaurant or cafe. There are strict government laws about working hours. Only children over 13 can work (there are some exceptions, for example, for actors.) On a school day they can work a maximum of 2 hours a day but not during school hours. At weekends and during school holidays they can work longer hours. The national minimum wage for people aged 16-17 is PS3.57 per hour. 18-year-olds must earn a minimum of PS4.83. There isn't a national minimum waged for people under 16. In Britain some children and teenagers have a bank account. There is no legal age limit at which you can open a bank account but a bank manager can decide whether to allow a child or young person to open an account. Parents can put pocket money directly into their child's bank account and then children can use it to pay for things without carrying money. Saving or spending pocket money, working part-time and dealing with banks are all parts of the process of becoming a financially independent adult and having to earn and look after your own money.

The following is the story of a SARS patient named Wang and his fight with the disease. I woke up around 6 : 30 this morning, on my ninth day in hospital since I caught SARS. Glancing over at my roommate, Xiao Huang, a 27-year-old employee of a Beijing software company, I saw he was also awake. After a light breakfast, a nurse came in and took my temperature. It was 36.6 centigrade. We're at Changxindian Hospital in southwestern Beijing, a newly named SARS patient hospital. It seems I am now recovering as my fever has gone down in recent days. When I first got the disease , I spent four days with a temperature above 39.5 centigrade--at one point it reached 40. 1 centigrade. At 8 : 30 am, a nurse took a blood sample and X-ray of my chest.

To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey, meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death. So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets _ , it constructs a wider-meshed (, )web using fewer strands . Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactivity, labeled materials, it was found that 95 percent of web protein reappears in the next day web. Most of the energy needed for web-building is used in walking over the strands as they are laid down. Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate . If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another. Which of the following best expresses the main ideas of the passage?

Amos Dudley, a 24-year-old boy who studies digital design at New Jersey University of Technology, felt ashamed about his teeth. But being a student, Dudley didn't have the money to get braces . So, he decided to 3-D print his own and marked down the DIY project in a recent blog post. His braces totaled less than $60, and after wearing them for 16 weeks, his teeth are also getting straighter. Months ago, he mentioned on his blog that he avoided smiling for a while because he was unhappy with his teeth. However, clear braces can get pricey, costing up to $8,000. But after studying some images of these expensive clear braces, something comes up on him--they looked like that one which can come from a 3-D printer. So he decided to hit up his school's 3-D printing equipment and scanned and printed models of his teeth. He then made non-harmful plastic molds around them to make 12 sets of braces. Dudley, who does not recommend attempting any of this at home said that he didn't ask a dentist for his project. But the student did get information from journal articles and textbooks. And though this was a perfectly friendly choice to buy braces. He didn't accept the project just to save money--he was also up for the challenge. "When I realized that I could do something that was a little bit special, while proving my skills as a designer and a maker, and fixing something that was making me self-conscious for actually free, I felt it was more than worth the risk." he said. The article is mainly about _ .

Cowboy or spaceman? A dilemma for a children's party, perhaps. But also a question for economists, argued Kenneth Boulding, a British economist, in an essay published in 1966. We have run our economies, he warned, like cowboys on the open grassland: taking and using the world's resources, confident that more lies over the horizon. But the Earth is less a grassland than a spaceship--a closed system, alone in space, carrying limited supplies. We need, said Boulding, an economics that takes seriously the idea of environmental limits. In the half century since his essay, a new movement has responded to his challenge. "Ecological economists", as they call themselves, want to revolutionise its aims and assumptions. What do they say--and will their ideas achieve lift-off? To its advocators, ecological economics is neither ecology nor economics, but a mix of both. Their starting point is to recognise that the human economy is part of the natural world. Our environment, they note, is both a source of resources and a sink for wastes. But it is ignored in conventional textbooks, where neat diagrams trace the flows between firms, households and the government as though nature did not exist. That is a mistake, say ecological economists. There are two ways our economies can grow, ecological economists point out: through technological change, or through more intensive use of resources. Only the former, they say, is worth having. They are suspicious of GDP, a crude measure which does not take account of resource exhaustion, unpaid work, and countless other factors. In its place they advocate moreholistic approaches, such as the Genuine Progress Indicator (GPI), a composite index that includes things like the cost of pollution, deforestation and car accidents. While GDP has kept growing, global GPI per person peaked in 1978: by destroying our environment we are making ourselves poorer, not richer. The solution, says Herman Daly, a former World Bank economist and eco-guru, is a "steady-state" economy, where the use of materials and energy is held constant. Mainstream economists are unimpressed. The GPI, they point out, is a subjective measure. And talk of limits to growth has had a bad press since the days of Thomas Malthus, a gloomy 18th century cleric who predicted, wrongly, that overpopulation would lead to famine. Human beings find solutions to some of the most annoying problems. But ecological economists warn against self-satisfaction. In 2009 a paper in Nature, a scientific journal, argued that human activity is already overstepping safe planetary boundaries on issues such as biodiversity and climate change. That suggests that ecological economists are at least asking some important questions, even if their answers turn out to be wrong. Which in the following will the author probably agree?
|
[
"the aims and assumptions of economics need to be revolutionized",
"GDP and GPI should be both accepted by mainstream economists",
"Human beings can always find solutions to all the annoying problems",
"Ecological economists' concerns about the world are worth noticing."

Students who want to attend an American university must explain how they will pay for their education. They have to show that they will be able to pay for each year of study. Students have to consider not only the tuition, the cost of classes, but also meals and a place to live in, which is known as room-and-board. They also need money for books and supplies. And they need money to spend on social activities and other things. Educational advisers say foreign students should have enough money in a local bank to pay for at least two months of expenditure . So how much will a year at an American school cost? Generally speaking, the answer is: a lot. A leading state university in the Pacific Northwest will serve as an example. The University of Washington says foreign students are paying more than $36,000 this year. This major research university currently has 2,600 foreign students from more than 100 countries. There are many schools that cost less, but also others that cost more. Its web site says the University of Washington does not offer financial assistance to international students. This is generally true of American schools, especially at the undergraduate level. The international application for the university includes a Statement of Financial Responsibility that must be signed. Students must also provide a bank letter or statement from within the past six months. And they have to name someone who will help with payments. These people must send proof from a bank to show that they have the money. Your government or employer may be able to help you pay all or some of the college costs. A good idea is to ask at least eighteen months before you want to start classes in the United States. Our Foreign Student Services, including links to web sites discussed in our reports, can be found at www.unsv.com. To learn more about higher education in America, the State Department has a special web site: educationusa.state.gov. What is NOT a must if you, a foreign student, apply for the university in the US?

Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were our in our front yards, watching seven children of age six and under ride their bikes up and down. "I wish I could take one of my children out alone," said Christie. Then we worked out a plan. When Christie takes one of her children out alone, I'll watch her other three. And when she watched two of mine, I will take someone out. The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She is like a different kid when there's no one else around," Christie shared with me quietly. With her mother all to herself, McKenzie didn't have to make any effort to gain attention. Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I'm always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who is always a follower when around other children, shines a leader during our times together. The "Mommy and Me" time allows us to be simply alone and away with each child--talking, sharing and laughing, which has been the biggest gain. Every child deserves an only child at least once in a while. Right after McKenzie came back, the other children were _ .

Dear Mary, I'm sorry to hear that you didn't get good grades in math mid-term exam. And you said you spend a lot of time studying math. However, it is difficult for you to learn it well. I think you should find a right way to learn it. Here is my advice for you. During the class * Listen to the teacher and be sure to write down everything the teacher puts on the blackboard. * If you don't understand a step or how to get the answer to the question, ask the teacher or a classmate for help right now. * Underline key points while taking notes. After the class * Recopy each day's notes into a new notebook clearly. * Do your homework every day carefully. And don't copy other students' homework. * If a step is unclear or you don't know how to do it, ask for help soon. _ * Look for useful examples of how this kind of difficult problem is used in your textbook or other materials Before exam * Review all of your notes quickly and find out every missing problem at times. * Work examples in the text each several times until you can do them quickly. This will help you improve the speed needed for the exam. If you do as I said, I think you will get good grades in the final exam. Come on! Mary. Which is the wrong way to learn math well?

Rare birds in the UK have been living far better than the more common birds over the last decade due to the efforts of conservation organisations, according to a new assessment. The research shows almost 60% of the 63 rare birds that live in the UK have increased over the last 10 years. By contrast, only about one third of common species have increased over the same period. Just 28% of rare birds have decreased over the same period, compared with four out of every 10 common birds. The rare birds described in the assessment with increasing populations include theosprey andcorncrake . All of these birds are subject to conservation action. The declining common birds include the nightingale,swift , house sparrow and redgrouse . These are suffering declines for a variety of reasons, including changes in farming practices. Dr David Noble, from the British Trust for Ornithology, said: "That some of our rarer birds have responded to targeted conservation action is great news. It shows just what can be achieved. What we need to do now is to continue the good work and use some of the lessons we have learned to help our more common birds." Dr Mark Avery, the conservation director of the Royal Society for the Protection of Birds (RSPB), said: "Over the last decade we've enjoyed some great conservation successes, including removing some threatened species from the World Conservation Union's Red List of Thratened Animals and increasing the populations of red kite, osprey, etc. However, these successes arecountered by continued declines of some widespread species." The overview of 210 native birds has been produced by a group of conservation organisations, to mark the publication ofThe State of the UK's Birdsreport, which is in its l0th year. The report was published by the RSPB for a group of conservation organisations. Which of the following can best explain Dr Mark Avery's words?

"The UK should not be satisfied with what they have achieved.",
"The UK should share their experience with other countries.",

On a hot summer day, ice-cold watermelons serve up a delicious treat. Sure, the rosy flesh quenches your thirst . But now there are more reasons than ever for people to reach for a slice of watermelon. Meet Dr Alison Edwards. She is a scientist at the Agricultural Research Service. Scientists are people who come up with new ideas called theories . They usually do scientific research to test their new theories. That's how they find out if a new idea is a good one, or if the new idea will bring an even better idea. At her lab, Dr Edwards recently learned more about the secrets of why watermelons are good for you! Dr Edwards has known for a long time that watermelons have vitamin C. But recently she learned that watermelons also have lycopene . It is something that gives tomatoes and watermelons their rosy red colour. What's so special about the lycopene in watermelons? Dr Edwards says that watermelons and tomatoes both have lots of lycopene. It seems that your body can use the lycopene from watermelons more easily than the lycopene from raw tomatoes. In fact, the lycopene from tomatoes is more easily absorbed inside your body once they have been cooked. Which of the following is TRUE according to the passage?

You cannot say that it's entirely true that kids learn a second language easily, but it's still the best time to learn. Babies are basically equipped to hear and distinguish every possible language and dialect, but once they reach 6 months old, they begin to focus on the particular sounds that exist in the languages that they're exposed to. In this way, kids will naturally and automatically be bilingual if they hear multiple languages on a daily basis when they are still babies. One lady told me of her son who grew up in a very multi-cultural community working at a resort. He would naturally and easily switch from Dutch, to French, to Italian, German and English depending on who he was talking to. Of course that's an extreme case, but it's completely possible and easy. It's not true that they will get mixed up by learning multiple languages. They may mix them up purposely simply because certain words or expressions are easier, but they won't develop any permanent language disabilities. Quite the contrary, bilingual children have been shown to be as much as a year more advanced in learning ability development for 2 and 3 years olds. Some kids who simply aren't gifted at learning languages, just as some aren't gifted at sports or music, will find it difficult to continue schooling in a foreign language. In that case, it may be better not to continue with the foreign language school. Perhaps for Grade Two you could try a bilingual school. In any case, learning even a small amount of a foreign language, maintaining the ability to hear and pronounce it by listening to music and movies will keep a foundation for later learning. Knowing a second language can be a great benefit for gaining employment. The lady told us that her son _ .

Imagine living in a city made of glass. No, this isn't a fairy tale. If you could grab your diving gear and swim down 650 feet into the Pacific Ocean off the coast of Washington State, you would witness the secret world of glass reefs. The reef you'd be looking at is made up of glass sponges . But how can animals be made of glass? Well, glass is formed from a substance called silica. The sponges use the silica found in ocean waters to build glass structures that will give them shape and support. Be careful! Some of the fragile creatures are up to 200 years old. When sponges die, new ones grow on top of the pile of old ones. Over centuries, a massive and complex reef takes shape. Some sponges look like wrinkled trumpets, while others look like overgrown cauliflower or mushrooms. Dr. Paul Johnson, who discovered the Washington reef in 2007, also found other surprises such as bubbles of methane gas flowing out of the seafloor nearby. The methane feeds bacteria, and the bacteria feed the glass sponges. "It's a new ecosystem we know nothing about," said Dr. Johnson. The reef of yellow and orange glass sponges is crowded with crabs, shrimp, starfish, worms, snails, and rockfish. The glass reef is also a nursery for the babies of many of these creatures and was called a "kindergarten" by scientists. Many animals that live in the reef hang around for a long time, just like the sponges. Rockfish, for example, live for more than 100 years. Scientists are just beginning to study all the species that call the reef home. The Washington coast isn't the only place where a living glass reef has been found. The first was discovered in Hecate Strait off the coast of British Columbia in 1991. Scientists all over the world were to see it. It can be learned that the glass reef _ .

Growing in Philadelphia, Lieberman started cooking with his stay-at-home dad when he was seven. His food-loving family had two kitchens, and quickly learned what was the best way to bake his cakes. Lieberman improved his kitchen skills greatly during a year abroad before college, learning from a cook in Italy and studying local specialties in Germany, Spain and France. At Yale, he was known for throwing dinner parties, single-handedly frying and baking while mixing drinks for dozens of friends. Just for fun, he and some friends decided to tape a show named Campus Cuisineabout his cooking. Lieberman was a real college student showing his classmates how to do things like make drinks out of dining-hall fruit. That helped the show become very popular among the students. They would stop Lieberman after classes to ask for his advice on cooking. Tapes of the show were passed around, with which his name went beyond the school and finally to the Food Network. Food Network producer Flay hopes the young cook will find a place on the network television. He says Lieberman's _ is key."Food TV isn't about food anymore,"says Flay."It's about your personality and finding a way to keep people's eyeballs on your show." But Lieberman isn't putting all his eggs in one basket. After taping the first season of the new show, Lieberman was back in his own small kitchen preparing sandwiches. An airline company was looking for someone to come up with a tasteful, inexpensive and easy-to-make menu to serve on its flights. Lieberman got the job.

Your next Saturday night takeaway could be brought to you by a robot after a major food delivery company announced plans to use automated vehicles to transport meals. Europe's biggest online takeaway food company Just Eat has partnered with Starship Technologies to deliver food with robots on the streets of London later this month. "Nobody has ever done deliveries with land-based robots," said Allan Martinson, the chief operating officer of Starship. The robot courier can travel up to 4 miles per hour for about 10 miles. It uses a GPS signal and nine cameras to navigate . Instead of a person arriving at their door, customers could find themselves receiving a notification on their phone that says a robot is on its way and a code to unlock the automated courier. "Put the code in, the robot opens up, and there's your food," said David Buttress, chief manager of Just Eat. The robot, which has so far been tested in Greenwich, Milton Keynes and Glastonbury, costs PS1 to transport within 3 miles, compared with the PS3 to PS6 it costs for a human courier. To date 30 robots have driven nearly 5,000 miles without getting into an accident or finding themselves picked on by passers-by. They have driven in more than 40 cities around the world, including London and Tallinn, Estonia. An initial worry was how the public would react to robots. But Martinson said the public has been calm when passing the delivery machine on the streets. "The most surprising reaction has been the lack of reaction," said Martinson. Another significant fear was that people would disrupt the robots, or try to steal them and their contents. To prevent this, the robot is fitted with nine cameras, two way audio, and movement sensors that send a warning if it is lifted off the ground. And it opens only with a pass code provided to the customer via a notification. "It's much easier to shoplift than it is to steal a robot," said Martinson. Which of the following would be the best title for the text?

Do you like drinking Coke? As a symbol of American culture, Coca-Cola is liked by many people, especially young people all around the world. But from now on, perhaps it will be hard for students in the US to get it on campus. A new agreement will end almost all sales of high-sugar fizzy drinks in US schools. The agreement allows only unsweetened juice, low-fat milk and water in primary and middle school vending machines and cafeterias. Former American president Bill Clinton helped the American Heart Association and the beverage industry to come up with the agreement. He suffered from a weight problem and has had a heart operation since leaving the White House. He takes the agreement as "a bold step forward in the struggle to help 35 million young people lead healthier lives". Rising childhood obesity has become a big problem in America. A federal report noted that obesity has _ among teenagers in the past 25 years. It called for new limits on the marketing of junk food to children. Soda is a particular target because of its caloric content and popularity among children. Britain has already taken similar steps to fight obesity. A recent study shows that people in the UK are much healthier than the people in the US. However, it's better late than never. Now American schools are trying to make new rules to guide the students to choose healthy drinks. American schools say goodbye to Coca-Cola. What kind of beverage is NOT allowed to sell on campus?

For thousands of years humans have used herbs , roots, and other things from nature to cure disease. Scientists looking for new cures often visit traditional healers. They find out what plants are used in healing. Then they look at what the plant contains. They find the active ingredient , which is the chemical in the plant that works to heal. Many of the drugs we use, including aspirin, have come from these natural medicines. In recent years, many people in the US have taking what are legally known as dietary supplements . They may be vitamins or minerals. They may be herbs that help with health problems, such as depression. Some of them are teas. Others are capsules or tablets. They are sold in natural food stores, drug stores, and groceries. Most people think that because these products are natural they are also safe. This is not always true. There are many plants that are poisonous. There are others that have bad side effects. The New England Journal of Medicine publishes medical research. A recent edition called for the government to _ dietary supplements. Several doctors wrote to the Journal and told of bad experiences people have had with dietary supplements. Dietary supplements aren't tested in the same way as drugs. There is not always proof that the supplement really does what it is supposed to do. There is also a problem with purity of the supplements. Supplements have been found to contain things that are bad for the body. For example, the California Department of Health found that of 260 herbs grown in China, one third contained heavy metals. These are minerals such as lead and mercury . They are very poisonous, even in tiny amounts. The scientists study the cures from the healers in order to _ .

Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. "I got really dizzy," she says. "I was out for a few minutes." At first, Amanda thought she was just tired and didn't think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out "because we were in heat so much with not enough water and not enough of the right kind of foods". Teens often don't want to stop and take a break or don't notice when they start to feel bad, doctors say. However, paying attention if you're not feeling well is important, as Amanda learned. As a result, Amanda has changed her habits. "I drink a lot more water," she says. "And put more salt in my diet. I'm eating more balanced meals." Amanda advises teen athletes to trust their coaches and speak up when they're not feeling well. "And recognize the difference between when you're tired and when there's something really wrong." Some people - up to 3 percent of the population - sweat too much, even in cold weather. The condition, called hyperhidrosis , can affect many parts and it often runs in families - hands down from generation to generation. Too much sweating over the whole body could be a symptom of another medical condition. Doctors aren't sure what causes hyperhidrosis, but using special medications or other treatments can help. What can we infer from Paragraph 4?

Whatever our differences as human beings are we all think we're more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic structure with the simple worm. But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome . To help them do this, they turned to the worm. The nematode worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better. What the worm told Sir John and his colleagues was that each of the cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up. Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death. People might be seriously ill if the cells in their body_.

What is the first thing you want to do when you see someone yawn ?You want to yawn, too! Yawning is _ Scientists have found that all people yawn. Babies start to yawn even before they are born. The earliest yawn takes place when a baby is still inside its mother. When young children are about one year old, they start to yawn when they see others yawning. That's why scientists seem to think yawning is contagious. It's no secret that yawning is contagious, but why do we yawn? Well, scientists are not really sure. Some think we yawn because we feel bored. Recently scientists studied two groups of students between the ages of 17 and 19. One group watched music videos, and the other watched a boring color test. Scientists compared the numbers of their yawns and found that the color test group yawned more times than the video group. Another reason for yawning has to do with breathing. Some scientists believe that when we are bored or tired, we breathe more slowly. As our breathing slows down, we cannot get rid of enough carbon dioxide, our bodies will tell the brains to breathe deeply. The result is a big yawn. In 2007, scientists suggested a new reason. They said that the reason why people yawned was to cool down their brains. These scientists found that people who were warmer than others yawned more often. Scientists are still trying to find out why yawning happens and why it is so contagious. But they are only sure that when one person yawns, almost everyone else nearby wants to yawn, too.

In the past, people who graduated from college felt proud of their academic achievements and confident that their degree would help them to find a good job. However, in the past four years the job market has changed greatly. This year's college graduates are facing one of the worst job markets. For example, Ryan Stewart, a graduate of San Jose State University, got a degree in religious studies, but he has not gotten any job offers. He points out that many people already working are getting laid off and don't have jobs, so it's even harder for new college graduates to find jobs. Four years ago, the future looked bright for his class of 2006. There were many high-tech("dot com") job opportunities, graduates received many job offers, and they were able to get jobs with high salaries and benefits such as health insurance and paid vacations. However, "Times have changed. It's a new market," according to an officer of the university. The officer says students who do find jobs started preparing two years ago. They worked during summer vacations, they have had several short-time jobs, and they majored in fields that are still paying well, such as accounting or nursing. Even teaching is not a secure profession now. Ryan Stewart wanted to be a teacher. But instead he will probably go back to school in order to become a college teacher. He thinks college teaching could be a good career even in a bad economy. In conclusion, these days a college degree does not automatically lead to a good job with a high salary. Some students can only hope that the value of their degree will increase in the future. It can be concluded from the passage that _ .

Can you imagine traveling to work in a one-man submarine? Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea. Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen. First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems. In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology. Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers. By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of the tides. Whether we live in the sea or in outer space, first of all we should think of _

Many grown-ups worry that spending too much time playing video games isn't good for a kid's health. But some doctors have noticed that kids who bring their game players to the hospital seem less worried about being there. They also seem to feel less pain when they are giving all their attention on a car race or other games. At a children's center in Baltimore, Maryland, young kids are finding hospital visits easier to deal with, thanks to a test program called HOPE. Patients in HOPE have a life-threatening condition where their kidneys no longer get rid of wastes from their blood. To get their blood cleaned, these kids must use the dialysis machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play Internet sports, racing, and other games with each other. They will be able to connect with kids in other hospitals who have the same problem. "We want to use the Internet to bring together kids who are ill, and let them know they are not alone," said Arun Mathews, the doctor of the program. He loved video games himself and got the idea to connect kids all over the country. Many researchers elsewhere are testing video programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, California, who was struggling with cancer helped to design a video game where players got rid of cancer cells. That's all great news, because doctors already know that reducing pain and worry helps patients heal faster. According to the passage, the sick kids may feel less pain when they _ .
