What will man be like in the future --- in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, because man is slowly changing all the time. Let us take an example. Man, even five hundred years ago, was shorter than he is today. Now, on average , men are about three inches taller. 500 years is relatively a short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still use only about 20% of the brain's capacity . As time goes on, however, we shall have to use our brains more and more, and finally we shall need our brains more and more, and finally we shall need larger ones! This is likely to bring a physical change too. The head, especially the forehead , will grow larger. Nowadays our eyes are used too much. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a long time it is possible that man's eyes will grow stronger. On the other hand, we make use of our arms and legs less. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a lot in modern life. But what about hair? This will probably disappear from the body because it does not serve a useful purpose any longer. In the future, then, both men and women are likely to be hairless. Perhaps all this gives the impression that future man will not be a very attractive person to look at! This may be true.However, future man will still have a lot in common with us. He will still be a person, with thoughts and feelings similar to our own. The passage mainly tells us that _ .

Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound. Noise can be caused by many kinds of machines, such as motorcycles, jet planes and farm tractors . Rock music is also noise. What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant loud noise can cause a loss of hearing. Scientists use a unit of measure called decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels. Noise at this high level causes the great hearing loss. We can conclude from the passage that _ .

A mosquito is a type of flying insect that lays eggs in puddles or small pools of water. When larvae develop from eggs, the larvae come to the surface to get air through special breathing tubes. After one to two weeks, the larvae become pupae and then turn into adults. How would a dry summer affect a mosquito population?

What can we learn from the special, very successful people in the world who make the impossible possible? Lesson 1: Ways of creative thinking are needed Bill Gates and Mark Zuckerberg both dropped out of college. They prefer to teach themselves because they like to develop their own ways of thinking. They think standard ways of teaching might stop people from being creative and having new ideas. Lesson 2: The answer might not be what you expect Find your answers from facts -- not start with an expectation of what you will find. Stephen Jacobsen from Northwestern University believed what he was taught: that water on Earth came from icy comets or planets which hit into Earth. However, by studying a special rock, he discovered that it acts like a sponge . This suggests that Earth's water may have come from inside, driven to the surface to form the oceans, by geological activity. "I had a pretty hard time making others believe it," he said. "But thinking about the fact that you may the first person to see something for the first time doesn't happen very often. When it does, it's amazing." _ Years of planning went into a recent achievement in space travel. The European Space Agency's "Philae", a robot landing craft, met up with Comet 67P, which is 480 million kilometers away. The trip from Earth by "Philae" had taken ten years! The scientists had no idea what the surface of the comet would be like. If the landing failed, it would be impossible to get information from the spacecraft. Twenty years of work would have been wasted. When "Philae" tried to land, it bounced away from the comet's icy surface twice. Luckily, however, "Philae" landed successfully and began sending information back to Earth. Bill Gates and Mark Zuckerberg didn't finish college because _ .

Healthy eating doesn't just mean what you eat, but how you eat. Here is some advice on healthy eating. Eat with others. It can help you to see others' healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious. Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty, sometimes you are just thirsty, you need no food. Stop eating before you feel full. Eat breakfast. Breakfast is the most important meal of the day. After you don't eat for the past ten hours, your body needs food to get you going. You will be smarter after eating breakfast. Eat healthy snacks like fruit, yogurt or cheese. We all need snacks sometimes. In fact, it's a good idea to eat two healthy snacks between your three meals. This doesn't mean that you can eat a bag of chips instead of a meal. Don't eat dinner late. With our busy life, we always put off eating dinner until the last minute. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to _ most of the food before you rest for the next 8-10 hours. Which is the most important in a day according to the writer?

Bags of Love Last year, I worked in a middle school near my mother's house, and I stayed with her for a month. During that time, I helped her do some housework and buy some food. After the first week, I noticed that the food was eaten up very quickly. Then I began keeping an eye on my mum. To my surprise, I found that she would put some of the food into a paper bag and go out with it at about nine every morning. And finally, I decided to follow her. I saw her taking the food to the street children. She would also spend a lot of time talking and playing with them. One day, I talked to a neighbour and found out that my mum was well-known in the area. The children were very friendly with her and even thought of her as their own mother. Then it hit me - why wouldn't she want to tell me about it? Was she worried that I would stop buying food if I found out? When my mum got home, I gave her a big hug .I told her she didn't need to keep it a secret from me. And she told me something about the children. Some of them lived with an old lady in a small house. Others slept on the street. For years, she was helping the poor street children by giving them food. After she told me everything, I was so moved by how selfless she was. She helped others in need. As her son, I was so proud of my mum. I continued to buy food for my mum after that. But I always added one more bag for her other children. How did the writer feel about his mum after she told him everything?

Whether you live in Seattle or the Sahara desert, the time has come to invest in a good raincoat or umbrella, a new study suggests. As global temperatures continue to rise, more "extreme rain" events--intense, cats-and-dogs downpours--can be expected, said thestudy, published Monday in the journalNature Climate Change. And that, scientists said, means an increased flood risk, particularly for the world's driest areas. The study challenges the idea that global warming is causingdry areas to become drierand wet areas wetter. "In both wet and dry regions, we see these great increases in heavy precipitation ," lead author Markus Donat, a climate scientist at the University of New South Wales, told Nature. Donat and his team collected data from 1951 to 2010 on extreme precipitation events from 11, 000 weather stations around the world, Nature reported. In that time, the number of days with "extreme precipitation" increased 1 percent to 2 percent per decade. "We found a strong relationship between global warming and an increase in rainfall, particularly in areas outside of the tropics," Donatsaid in a statement. "Importantly, this research suggests we will see these extreme rainfall events increases at regional levels in dry areas, not just as an average across the globe," Donat added. Peter Stott, a senior climate scientist at Met Office, told Climate Central that the study's findings are important, because more violent rainfall and flooding will "challenge our capability to adaptto a rapidly changing climate." As Nature reported, the research aligns witha 2015 study that found global warming has led to a sharp increase in record-breaking precipitation events. Donat told Nature that his study should come as a warning to world governments. Which of the following is one of the study's findings?

"Global warming is causingdry areas to become drierand wet areas wetter.",
"Extreme rain events can be expected at regional levels in dry areas.",

The Intel Science Talent Search is the top science competition for high school students in the US. The 40 finalists were honored in Washington last week. They met with scientists and politicians. President Obama welcomed them to the White House. These 40 students were selected from almost 2,000 contestants nationwide. They had to present original research to be judged by professional scientists. The students showed their research projects on large posters. The winners were announced on March 15th, 2011. Wendy Hawkins is executive director of the Intel Foundation, who says the 40 finalists represented excellence across many areas of science. Selena Li is from Fair Oaks, California. She wanted to find a more effective treatment for liver cancer. She began her research four years ago. A scientist at the University of California, Davis, taught her how to design and do experimental work in the laboratory. Ms. Li placed 5th in the Intel Science Talent Search and was awarded 30,000 dollars. Scott Boisvert lives near Phoenix, Arizona. He began using a laboratory at the University of Arizona at the age of 14. Over four years, he completed a project studying a fungus linked to the decrease in amphibians around the world. He was trying to find out if different chemicals and substances in the water could kill the fungus. He collected and tested water samples across Arizona. He says, "My results were able to identify a list of chemicals that were significant in the growth and in the movement of the fungus." He placed10th in the Intel competition and was awarded 20,000 dollars. Evan O'Dorney of Danville, California, won the top award of 100,000 dollars in this year's Intel Science Talent Search. For his mathematical project, he compared two ways to estimate the square root of an integer , a number with no fractional parts. Wendy Hawkins at the Intel Foundation says these young people represent the next generation of scientists who will help shape America's future. According to the passage, if you want to win the Intel Science Talent Search, you must _ .

One cold winter morning, an old woman had to go to see her doctor. When she walked into the doctor's office, she told him that her right leg hurt and sometimes she could not walk. She asked him what was wrong. She told him that she had never had such a feeling before. The doctor checked the old woman carefully, then he said, "You're in good health for a woman of your age. I think the trouble in your right leg is just a matter of old age catching up with you. We get all kinds of illness as we get older. The trouble will almost certainly end in spring." "I don't think so, doctor!" she said. "My left leg is well, and it's the same age as my right one." What did the doctor think of the woman?

Pessimistic,anxious and depressed people may have a higher risk of dementia ,US researchers reported on Thursday. A study of a group of 3,500 people showed that those who scored high for pessimism on a standardized personality test had a 30 percent increased risk of developing dementia 30 to 40 years later. Those scoring very high on both anxiety and pessimism scales had a 40 percent higher risk,the study showed. "There appears to be a doseresponse pattern.That is,the higher the scores,the higher the risk of dementia,"Dr Yonas Geda,a neuropsychiatrist at the Mayo Clinic in Rochester,Minnesota who led the study,said in a statement. Geda and his colleagues looked at the medical records of 3,500 men and women who lived near the clinic between 1962 and 1965. They all took the Minnesota Multiphasic Personality Inventory,a standard personality and life experience test,Geda's team told a meeting of the American Academy of Neurology in Miami. In 2004,the team interviewed the participants or family members. Those who scored higher for anxiety and pessimism on the test were more likely,as a group,to have developed dementia by 2004,including Alzheimer's disease and vascular dementia. This did not mean a person who is pessimistic could assume he or she has a higher risk of developing dementia. "One has to be cautious in interpreting a study like this,"Geda said. "One cannot make a leap from group level data to the individual.Certainly the last thing you want to do is to say,'Well,I am a pessimist;thus,I am doomed to develop dementia 20 or 30 years later,'because this may end up becoming a selffulfilling prophecy ." And there is NOT any specific way to prevent dementia,although many studies have shown that a healthy diet,exercise,keeping active in other ways,doing puzzles and other activities lower the risk. What is the passage mainly about?

"It is impossible for people to avoid dementia.",

As Rosalie Warren stood at the mailbox in the lobby of her apartment building in May 1980, she shared the anxiety of many other college seniors. In her hand was an envelope containing her final grades. As she nervously opened it, Warren wondered whether her hundreds of hours of studying had paid off. They had. "I got five 'A's," she still recalls with elation. "I almost fell on the floor!" Warren would graduate from Suffolk University with a bachelor of science degree in philosophy and history at age 80.Three years later, at age 83, she would receive her second degree from Suffolk, a master's in education. Now, with both diplomas proudly displayed in her apartment, Warren is not finished with learning. "That's what I love." Warren was born Rosalie Levey on Aug.29, 1900. Two years after she entered high school, her father died. Warren had to leave school for factory work to help support her family's 10 children. Warren describes herself as a "person who always liked school," and she says the move "broke my heart completely because I couldn't finish high school." In the end, however, "I went to school nights," she recalls. "Any place I could find an outlet of learning and teaching, I was there." A short time later, her mother became ill, and Warren had to care for her, once again putting her education on hold. Finally, in 1921, her mother, now recovered, drew from her saving to send Warren to Boston University for two years to study typing, stenography, and office procedures. Those courses helped Warren gain several long-term office positions over the next 60 years, but her great desire "to be in the academic field" continued. In 1924, she married Eugene Warren, and seven years later, her daughter, Corinne, was born. In 1955, by then a widow and a grandmother, Warren took a bus tour across the United States that was to last nine months. She said she wanted to see "things you never see in the West End." When she returned home, she took a bookkeeping position and also enrolled in courses in philosophy, sociology And Chinese history. free program for senior citizens."

"I had not studied for so many years," she says, "but I was determined." For the next four years, Warren, who calls herself a "student of philosophy," worked toward her degree. Nancy Stoll, dean of students at Suffolk, says Warren is "an interesting role model for our younger students---that learning is a lifetime activity....She is genuinely enthusiastic about being here, and that permeates her activities and is contagious to students and faculty." What kind of work did she do for 60 years?

Some children cannot wait to grow up. Because once you become an adult, you are free to make your own decisions. More importantly, you can do all those things that you cannot do now because you are too young. So, the question is, 'At what age do you really become an adult?' Well, people become adults at different ages in different places. In Australia, the 18th birthday is a very important event for young Australians because it means they can do almost anything they want. They can vote, learn to drive a car, get married, join the army and even buy their own houses. However, even if they can do all these things, most Australians have to wait until their 21st birthday to really celebrate becoming an adult. This is the traditional adult age not only in Australia, but also in the USA and the UK. It is their first year of true independence .Traditionally, people were given a key to their houses by their parents when they turned 21, meaning they could come and go as they like. Even though 21 is the traditional adult age in many English-speaking countries, the law nowadays is different in each country. In the UK, you can join the army at 16 and even get married at 16 if your parents allow. Young people in the UK can learn to drive a car at 17 as in Australia, although they have to wait until they are 18 to vote. In China, there is a different age for each of the stages of becoming an adult. You can vote and learn to drive a car when you are 18, but if you want to get married, women have to wait until they are 20 and men until they are 22. Chinese people celebrate important birthdays every 10 years--so when young people turn 20, they can expect a big party! No matter what age you are, becoming an adult is really about learning how to be independent and responsible . Once you are finally able to take care of yourself and make your own decisions, then you can say that you are truly all grown-ups. At what age do Australians really become adults?

McDonald's Corp, founded in 1940 with a restaurant opened by Dick and Mac McDonald, which was bothered by criticism of its fatty foods, says it will remove Supersize French fries and soft drinks by the end of the year, to please health-minded customers. McDonald's Supersize option, which includes a 7-ounce fries carton and 42-ounce fountain soda, has also been targeted by critics as contributing to a growing obesity crisis in the United States where more than half the population is considered _ . From a neighborhood restaurant established in Des Plaines, Illinois in 1955 to today, more than 30,000 restaurants in more than 100 countries worldwide, McDonald's is the largest quick service restaurant organization in the world, selling primarily variations on meals consisting of hamburgers, carbonated drinks besides French fries. As the first international fast food company, McDonald's has become a focal point in public debate about rising obesity rates and consumer responsibility. Most standalone McDonald's restaurants offer both counter and drive-through service, with indoor and sometimes outdoor seating. The larger McDonald's grows, the more sensitive it becomes to negative customer understanding. According to this, McDonald's has tried to cater to varying cultural requirements, such as by customizing its menu to each country. The company, which began offering Supersize portions widely in 1994, said it is making the menu changes to "support a balanced lifestyle" approach that is in keeping with other recent moves to promote healthier behavior. These include a planned national launch of a Happy Meal for adults called Go Active! In the past year, it has introduced several health-oriented foods, such as entree-sized salads and healthy alternatives in children's Happy Meal, including milk and fruit. A new documentary film, called Super Size Me illustrates the negative effects of over-consumption of McDonald's food. The film has been released, but a McDonald's spokeswoman said that the menu changes are not related to any impact of the film on public awareness. McDonald's recognized that to be successful, it would have to be flexible and adapt to social changes. The company has been reducing complexity of its menu, part of a broader push to improve operations and service in its more than 13,000 US restaurants. Analysts said the change will allow McDonald's to continue its emphasis on foods with higher-quality elements and more money-earned, such as entree-sized salads and all-white-meat Chicken McNuggets. In order to support a balanced life style, which measure has the company NOT taken?

No one would much like the idea of eating 61 pounds of tomatoes a day. But if their goodness was put into an easy-to-swallow pill that you were told might prevent strokes and heart attacks you would probably be putting in an order tomorrow. Researchers believe they may have come up with just that after trials. The daily pill contains a chemical called lycopene which makes tomatoes red and is known to break down fat in the vessels . A Cambridge University study found taking the pills improved blood flow and the lining of vessels in patients with pre-existing heart conditions. It also increased the flexibility of their vessels by 50 percent. The scientists believe it could limit the damage caused by heart disease-responsible for 180,000 deaths a year-and help cut the 49,000 deaths a year from strokes. They also hope it could benefit those with arthritis , diabetes and even slow the progress of cancer. Each pill is equal to eating around 61 pounds of ripe tomatoes. Studies have shown eating a Mediterranean-style diet rich in tomatoes fish, vegetables, nuts and olive oil can significantly reduce cholesterol and help prevent cardiovascular disease. Preliminary results from a two-month trial, in which the pill was given to 36 heart disease patients and 36 healthy volunteers with an average age of 67, were presented at a meeting of the American Heart Association. It was shown to improve the function of the endothelium- the layer of cells lining blood vessels. It also improved their sensitivity to nitric oxide, the gas which causes the enlargement of the vessels in response to exercise. Ian Wilkinson, head of Cambridge University's clinical trials unit, said "These results are potentially very significant and it meets the goal, but we need more trials to see if they translate into fewer heart attacks and strokes." Further studies are planned, with researchers hoping it could offer a choice for heart disease sufferers who can not take the cholesterol-lowing drugs. Mike Knapton, head of the British Heart Foundation, said, "Although this showed lycopene improved blood flow in people with heart disease, that's a long way from demonstrating that taking it could improve outcomes for people with heart disease. The best way to get the benefits of a good diet is to eat plenty of fresh fruit and vegetables." What Was Ian Wilkinson's opinion on the trial?

One Monday morning, Paul and his classmates were in science laboratory for their practical chemistry lesson. The students were going to work in pairs to do an experiment. Before they began, the teacher gave them this description of the different stages of the experiment. Stage 1: Prepare the equipment: a test tube, a crucible, a Bunsen burner and tongs. Stage 2: Weigh 5 grams of baking soda (sodium bicarbonate) and put it in a crucible. Stage 3: Heat 10 ml of hydrochloric acid in a test tube. Stage 4: Pour the warm acid onto the baking soda and continue to heat the mixture. Result: The acid reacts with the bicarbonate to form water, carbon dioxide gas and salt. The hotter the mixture, the quicker the reaction. Continue to heat the mixture until the water evaporates, leaving the salt in the crucible. Paul and his partner followed the instructions and set up their equipment. Paul went to the cupboard to get a bottle of hydrochloric acid. He found that there was only one bottle in the cupboard so he took that. There was no label on the bottle and Paul didn't check with the teacher if it was the right solution. He measured the liquid and poured it into a test tube. Using tongs to hold the test tube, he heated it over the Bunsen burner. That's when things started to go wrong.

All the students started coughing and their eyes hurt. The teacher immediately opened the windows and ordered the students to leave the laboratory at once.

One day, I had a bad toothache. I couldn't eat anything. So I went to see the dentist. " What's wrong with your teeth? " asked the dentist. " I have a toothache. " I told him. " Let me see your teeth ...... Um, there's a hole in one of the teeth. Do you eat a lot of sweet food? " The dentist asked me. " Yes, I do. I often eat ice cream, biscuits, chocolate and I often drink cola and milk with sugar, " I told him. " All these are bad for your teeth. You must eat less sweet food and brush your teeth at least twice every day. Now let me fill your bad tooth. " Which of the following is true ?

This could be the perfect gift for the partner, who embarrasses you on the dance floor. Smart socks, which can teach to dance, may be the answer for _ The socks have been developed as a running tool to help runners improve their skills. Thanks to the socks, users can accurately record not only know far and fast they run but also how well. It means the user maximizes theirperformance, and reduces damage to body and prevents hurt. The hi-tech socks are made of special fibers that watch the movements of your feet. They look, feel and can be washed like normal clothes. Sensorsrecordeach movement and send it by an ankle transmitter to a smart phone. Then a "virtual coach" application shows the information and can tell the user what they are doing wrong, and help to improve skill in any task with feet. The socks should be useful to athletes and weekend joggers. "People think running is so easy and of course everybody can do it but not necessarily safely and well," Dr Davide Vigano said. A recent study showed that between 60 and 80percent of runners got hurt per year. This is pretty much more than any other human activity. Researchers say the technology can also be developed to teach people how to dance, play sports such golf, or even to help to teach women to walk better in high heels. Mr. Vigano said, "People could all benefit from the idea. We have had interest from all sorts of sports, like skiing, football, cycling and golf. Anything where you have to use your feet can use it. It could even be put in high heels to help women walk in them safely." Socks are just the start, and the technology could be used in gloves, hats and boots. The socks, anklet and software package, are expected to be sold for around PS120, which will go onsalein March. According to Dr Vigano, _

Kiss crisis, hug horrors and the UK's handshake headaches Greeting someone, saying goodbye - these situations fill me with unease. You have a second to make a dangerous decision. One peck ? Two pecks? Three? No kisses at all? Why, I think, as I crash into the other person's face, why can't it be as simple as a handshake? A survey by the soap company Radox in May showed one in five Brits now feels a handshake is "too formal", according to the Daily Mail. Some 42 percent said they never shook hands when greeting friends. For one third of people the alternative was a hug, for 16 percent a kiss on the cheek. British people are known to be reserved - unfriendly, some would say. Handshakes used to work for us because we didn't have to get too close. But the super-British handshake is no longer fashionable. We want to be more like our easygoing Mediterranean neighbors who greet each other with kisses and hugs. The trouble is, we still find it a bit awkward. What does a married man do when greeting a married female friend, for example? How should someone younger greet someone older? Guys don't tend to kiss one another; my male friends in Britain go for the "manly hug", taking each other stiffly in one arm and giving a few thumps on the back with words like "Take it easy, yeah?". The biggest questions, if you do decide to kiss, are how many times and which cheek first. Unlike the French, who comfortably deliver three, our cheek-pecks usually end in embarrassed giggling : "Oh, gosh, sorry, I didn't mean to kiss you on the lips, I never know where to aim for first!" But then it's never been easy for us poor, uncomfortable Brits. Even the handshake had its problems: don't shake too hard, but don't hold the other person's hand too limply either, and definitely don't go in with sweaty hands. Maybe it's better to leave it at a smile and a nod. What did the survey by the soap company Radox show?

These days there are lot of possibilities to be always connected to family and friends. Now that I have just moved lo France, this can be very convenient. 1 can ring my sister who lives in Los Angeles on Viber, or I can Skype my parents or friends back in England for a chat. However, sometimes the convenient and dependability of technology can be _ . Even the most out-going people need some "down time" to calm down on their own and get relaxed. This is something that I consider necessary and healthy. After all, you have to live with yourself for the rest of your life, so you'd better know how to enjoy your own company. It can be a good thing to have time to yourself to collect your thoughts and free your feelings. Today 1 went for a walk by myself around the lake and just dav-dreamed. It was so relaxing and enjoyable and helped me let go of my bad emotions. However, somehow it seems rude or perhaps makes people feel that you'reupset to sayto people:" I'm going to go and spend sometime by myself. " Andoften when we are spending time 'alone' , we are actually connected with a piece of electrical equipment. We try to make something into a Facebook or a Tweet to attract our friends, or we scroll (> through Facebook nosing into other people's lives orseeing what friends are up to. We judge ourselvesand other people by the photos they put online, so we can tell how much fun they are having compared to us. This is an age when we can get so much surface information about other people's lives, but being wrapped up in what other people are doing or always thinking about other people's recognition of us can be quite unhealthy. Perhaps these days forget about the simple pleasure of spending time just for us. Having said all that, I also think that spending too muchtime byyourself can separate you from others. I suppose it is important to find a good balance between spending valuable time by yourself and with other people. What does the writer think of being alone properly?

In 1977 , a dead author of detective stories saved the life of a nineteen-month-old baby in a most unusual way. The author was Agatha Christie, a gentle married lady and one of the most successful writers of detective stories in the world. ks5u In June 1977 , a baby girl became seriously ill in Qatar , near Sandi Arabia . Doctors were unable to find out the cause of her illness, so she was flown to London and sent to Hammersmith Hospital. A team of doctors hurried to examine the baby only to discover that they, too, were puzzled by the very unusual signs of illness. While they were having a discussion about the baby's illness, a nurse asked to speak to them. "Excuse me," said Nurse Marsha Maitland, "but I think the baby is suffering from thallium poisoning ." "What makes you think that?" Dr. Brown asked. "Thallium poisoning is very rare." "A few days ago, I was reading a novel called 'A Pale Horse' by Agatha Christie," Nurse Maitland explained. "In the book, somebody uses thallium poison, and all the signs are exactly the same as the baby' s . " "You are very careful and you may be right," another doctor said. "we'll carry out some tests and find out whether it' s thallium or not." Tests showed that the baby had indeed been poisoned by thallium. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later on it was proved that the poison might have come from an insecticide used in Qatar. Who first suggested the correct cause of the baby's illness?

Mars Was Not Always Bitterly Cold Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today. The Caltech scientists say they have directly _ the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented. The Caltech scientists say carbonate minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite that had its beginnings near the Martian surface. Today, the average temperature on Mars is sixty-three degrees below zero Celsius. The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have confirmed the information. Caltech Geology Professor John Eiler was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information. It shows that early in the planet's history, at least part of Mars could support a climate like that of Earth. The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars' surface when another space rock struck its "home." How did Allan Hills meteorite get its name?

When they see birds fly high out to the sea, they know it is a nice day, because birds don't like to fly out if it rains. When the weather is bad, the birds will come back to the beach. A big wind may come with a rain. Birds do not like to fly in a big wind. They may sit in a tree when rain is coming. Other animals can also _ the weather. It is a cloudy day. The rain is coming.

A US student has just spent 30 days on an "insect diet " - eating insects three times a day. Camren Brantley-Rios says traditional meats such as pork and beef are unable to continue and he wanted to try out what many consider the diet of the future. Many people would not like the idea of eating insects distasteful, even if it were not disgusting. Not so long ago Brantley-Rios was among them. But for the last month he has been eating insects for breakfast, lunch and dinner. "I'm mainly sticking to three kinds," he says. Occasionally he has included different insects. Preparing these he "actually cried", though he insists they were surprisingly good. Insects consume fewer resources than animals, like pigs and cows, to produce the same amount of protein , Brantley-Rios says - and more than two billion people worldwide include insects in their regular diet, according to the UN Food and Agriculture Organization. "There's not really a need to eat insects in America because we have it so nice," Brantley-Rios says. "We have finer meats and we're lucky to have that luxury , so there's not much of a pressure to eat insects right now. But what a lot of people are trying to do is make it a little bit more marketable." He has ordered insects from farms that usually supply zoos, which need them "to feed certain animals". He has always made sure the insects have been fed on an organic diet, he says, and only bought species he knows are safe to eat. He knows that one person eating insects won't make much difference. To have a real environmental effect, millions would have to follow his example. How does Brantley-Rios guarantee the safety of his insect diet?

If you live in the United States, you can't have a full-time job until you are 16 years old. At 14 or 15, you work part-time after school or on weekends, and during summer vacation you can work 40 hours each week. Does all that mean that if you are younger than 14, you can't make your own money? Of course not! Kids from 10-13 years of age can make money by doing lots of things. Valerie, 11, told us that she made money by cleaning up other people's yards. Lena, 13, makes money by knitting dog sweaters and selling them to her neighbors. Reisa said she had started taking art classes and showing her works to people. People ask her to draw pictures for them and they pay her for them. Jasmine, 13, writes articles for different magazines! Kids can learn lots of things from making money. By working to make your own money, you are learning the skills you will need in life. These skills can include things like how to get along with others, how to use technology and how to use your time wisely. Some people think that asking for money is a lot easier than making it; however, if you can make your own money, you don't have to depend on anyone else. The five dollars that you make will probably make you feel a lot better than the twenty dollars you ask for. If you are 15 years old, you can't work part-time _ .

There are several reasons for hair loss in women. However, in most cases, treatment is quite effective. Female hair loss patterns in women are not as easily recognizable as they are in men. A woman may experience it temporarily due to pregnancy or illness, although they may experience it for other reasons. Hair loss can be due to a variety of factors, including a genetic tendency (which is not genetically linked to just one parent--both parents contribute to the tendency to lose hair). Women who are experiencing hair problems seem to have more limited choices than men. There are some female hair loss treatments that are available such as the Tricomin System which is a topical treatment that is nutrition based. Shen Min for Women is another natural treatment that contains herbs that are said to stimulate hair growth and even restore hair that is graying to its natural color1. The majority of the popular, prove hair loss treatments are only intended for men and are not suitable for women. True, a woman's hair issue is different from a man's. The biological makeup is different and the needs are different. Women have different needs and their bodies react in different ways to environmental changes, physical illness and even the treatments that are available. There are many natural treatments such as vitamin and mineral supplements that are said to stimulate hair growth, but, for the most part, these claims are currently unproven. One of the first and most important factors to effectively treating is to get a diagnosis from a doctor. Talk to your doctor about any symptoms that you may be experiencing in addition to the thinning hair. Stress, weight loss or gain, illness and depression, all of these can be contributing factors.

There are all kinds of food in the world. Some people like the Chinese food. Firstly, the Chinese food has a lot of fruit and green vegetables. It has little sugar and fat. Secondly, the Chinese food is very delicious and has many dishes. So Chinese people can keep fit and have white teeth. However, some people enjoy the western food. Now many people, especially the workers in companies , are too busy to have lunch slowly so the western food meets their need and they can eat quickly. And the food is not too bad, too. It is a great pleasure to try eating a different style of food. In my opinion, I like the Chinese food more than the western food. First of all I'm a Chinese and used to Chinese food, it can keep us healthy. On the other hand, the western food is high in fat, sugar and salt. If you eat too much these food and don't take enough exercise, you'll get fat easily. The western food is too expensive and "not good value for money". There are _ food in the world.

Every year mobile phones develop. Imagining what they will look like and be able to do in 2020 is really a challenge. To help, experts have outlined three major mobile trends that they believe will have become reality by then. Our phones will be so smart in 10 years' time that they'll know everything about our situation and warn us when something needs our attention. This is the top prediction of both Nokia and Google. They predict that our cars and home appliances will be able to communicate with our mobile. For example, fridges will tell your mobile to tell you to pick up milk on the way back from work. While driving, your mobile will suggest that you take a different route because there's a road accident up ahead. The second trend is in gesture-based controls. People who know the iPhone's touch-sensitive screen are already familiar with the technology. It translates hand movements into actions on-screen. But gestural communications will make the phone more convenient to use and may completely replace touchpads. According to industry insiders, the most immediate step forward in gestural technology will be in voice recognition. It's believed voice recognition technology will speed up communications. It is quicker to speak than type. Eventually, phone screens will disappear. The third major development will change our understanding of a mobile phone. From a single phone, the mobile will be developed into multi-part devices. It is opposite to the current trend in which mobile phones are combining the functions of cameras, music players and game consoles. The prediction is based on the idea that the world will become more wireless and all these--cameras, music players and game consoles--will be wirelessly connected. Mobile phones won't need to contain these devices because users will be able to control them wirelessly through their phones. The text mainly tells us _ .

What's a good friend like? One may have different answers to this question at different ages. When he is very young, he may think a good friend must be together with him all day. And they can share everything together. If his friend doesn't give him food to eat once, he doesn't think they are good friends any more. But they will play together happily again very soon. When he grows older and studies in a middle school, his idea about a good friend changes. He thinks a good friend should be helpful and honest. A good friend should always help him with his lessons. A good friend should come to him when he is sad. And he is always ready to tell everything to his friend. If his friend tells others about his secrets, he may hate the friend. When he grows up, he may not think it's necessary for a good friend to be always honest. Everyone has his secrets. If the truth may hurt the friend, it's better to keep it secret from him than tell him about it. And he may think a good friend can give him some good advice when he has problems.

The Toyota Prius hybrids adapted by Google's engineers have covered 300,000 miles on the roads of California without a human at the wheel, but with only one accident by a human-controlled car.It's clear that driverless cars are much safer than human-controlled ones.40,000 people are killed every year in road accidents in the US, many of which are caused by human error.Besides, driverless vehicles could make better use of the road and reduce the size of car parks, too. With technology, a machine can perform a complex task without human involvement This means our thought about what machines can and cannot do needs updating urgently. However, ignore the beautiful words and think about what Google has done.This isn't just about care.Economists are increasingly puzzled by the fact that the rate of job-creation is much lower than expected and the length of time for which people are unemployed has rocketed to 40 weeks twice as long as that during any previous postwar recovery.Economic theory says that when companies begin to grow or become profitable again, they buy equipment and hire workers.But that isn't happening.Companies are still buying equipment, but they're not employing workers. So where did the jobs go? Andrew McAfee explains his view in his new book Race Against the Machine." Advances in self-driving car by Google represent the next wave of job-eliminating technology.Many skills (such as driving) may eventually become worthless, at least in the job market." And as for those thinking that driverless cars might appeal to most motorists, there is the uncomfortable fact that the car has peaked.We are driving less year on year.Traffic jams reduce the romance from driving.And young people no longer have the desire to own cars like they used to. What will be the influence of driverless cars according to Andrew McAfee?

Dear daughter, You are a wonderful person and your mother and I think the world of you. It will not be long before you leave home to make your way in the world. Can I please give you some friendly advice? Here are some things that you should never do. 1. Never Look Down Upon Yourself. You are great and able to achieve great things so believe in yourself. When things go badly, never stop believing. Some girls get upset, blame themselves and lose self-esteem. All kinds of problems can follow. 2. Never Get Obsessed With Your Appearance. We think you look great (though some of the clothes you wear worry us!). Please be happy with the person ,you are and the body you have. Eat reasonably, take exercise and be healthy. Some girls show too much concern about losing weight or getting the perfect shape. You look fine. 3. Never Compromise Your Personal Safety. _ . This means that you cannot trust people until you really know them and that sometimes you have to avoid things that look like they might be fun. Never get drunk or take drugs. Unluckily there are some bad people out there and it is best not to take risks. 4. Never Give Less Than Your Best. We are very proud of what you have achieved so far. You should be proud too. Keep doing well. Keep trying your hardest at everything you do. No one can ask for more than that. 5. Never Forget That Your Parents Love You. Whatever happens in life, your family will still be your family. Whatever difficulties you meet with, you can always talk to us and we will try to help. We are here for you. The father advises his daughter not to _ .

In 1975, George Carlin appeared on a popular TV show, Saturday Night Live, with his famous words about blue food. "Why is there no blue food? I can't find blue food--I can't find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. Where is the blue food? " Well, Carlin pretty much has it right--there's not no blue food, but there's certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries--like the purple in grapes and the red in tomatoes--is found in nature. But it isn't a hot color for food. People don't seem to prefer blue food. Some diet programs even suggest that those determined to lose weight should make their food blue. Eating, in part, begins with our eyes. Charles Spence--an experimental psychologist from Oxford University--points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching - green fruits can become sweet as they grow up and turn red. But what about blue? Except blueberries, much of the blue food we see these days _ blue artificially. Food producers argue that artificial color doesn't do much harm to health. A lot of research shows that some physical problems of kids are related to food dyes--while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what? George Carlin's words are placed at the beginning of the passage to _ .

Body language is the quiet, secret and most powerful language of all! It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying. Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy. Head. When you want to appear confident, keep your head level. If you are a monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little. Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still. Posture .A good posture makes you feel better about yourself. If you are feeling down>> you normally don't sit straight, with your shoulders inwards. This makes breathing more difficult, which can make you feel nervous or uncomfortable. Mouth. When you are thinking, you often purse your lips. You might also use this position to hold back an angry comment you don't wish to show. However, it will probably still be noticed, and people will know you're not pleased Face. When you lie, you might put on a false face. But that expression would crack briefly, allowing displays of true emotions such as happiness, sadness, disgust and fear to come through. If you want to appear confident, you should_.

Americans eat breakfast and lunch quickly unless it is a social business or family occasion. The evening meal is usually longer and a time for families to gather together. Rushing through daytime meals is part of the fast pace in America. Another reason for rushing through daytime meals is that many people eat in restaurant that are usually crowded with people waiting for a place so that they can be served and return to work at the proper time. So each one hurried to make room for the next person. As there are busy people everywhere, there is a real difference with meals that are eaten in a hurry and those that can be enjoyed slowly with friends. Americans hurry at meals because _

Once upon a time,a hippo lived in a river next to a big tree. One day,a bird came and nested in the tree.The songs of the bird filled the hippo with so much envy that he couldn't think of anything else.Every day he would think why he wasn't born to be a bird even though the bird told him many times he was so lucky to be so big and such a good swimmer. Finally,the hippo made up his mind that he would come out of the river,climb the tree and start singing.However,when he tried to climb the tree,it was very clear that the hippo didn't have wings,nor claws to climb with. Realizing that he would never climb up the tree,he angrily hit the tree until it came crashing to the ground.Then he stepped onto the leaves of the fallen tree,and began singing. Unfortunately,hippos can't sing,either.All that came from his mouth were terrible noises,and when the other animals heard this,they all came around to make fun of the hippo. He was so ashamed by this.He also felt bad about having knocked the tree over.He used all his strength to raise the tree back up again,and look after it until it completely recovered. .

Michelle, a famous lady, has found that more than 25% students are too fat in her country. It is a very serious problem. So she starts a health program to deal with it. The health program is to reduce the amount of fat students today and in the future. The program will get families, schools, newspapers, magazines and TVs to join together and deal with the students' obesity so that students will be at a healthier weight. The program includes: Food stores should sell healthier foods. Schools should serve healthier meals with less fat and should also offer gym classes. The lady is trying to fight the students' obesity all over the country because it can cause illnesses and higher health cost. She wants the students to eat right, exercise more and control their weight. She also wants the students to understand it is important to have less sweet food, and drink water, milk and fresh juices, but not to choose cokes. At the same time she has also set a good example by planting a vegetable garden. She hopes that the garden will encourage more people to plant one, too. The health program is really helpful to the students today and in the future. As she says, we cannot always build the future for youth, but we can build our youth for the future. What does the lady want the shops to do?

Different exercise types have different purposes and different benefits. One type of exercise may not accomplish all goals of being physically fit: a healthy heart, strong muscles and bones, and safety from injury. As a result, it is important to do enough types of exercise to have all the physical benefits. Here is a quick check sheet. Aerobic Exercise: To have a strong and healthy heart, you need to do aerobic exercise. This means that you need to exercise yourself enough so that your heart rate, while exercising, is 65 percent to 85 percent of your maximum heart rate. If you don't get your heart rate up within this level--you just aren't working hard enough. Whatever you do, your heart rate needs to be 65 percent to 85 percent of your MHR for 20 to 30 minutes, at least 3 times a week. Typical types include: * Running * Walking (at least 4 to 4.5 mph) * Swimming * Bikingk3s5u * Elliptical Training * Yoga Strength Training: To keep your muscles and bones strong, you need to do strength training. This comes in a variety of forms. Whatever you do, however, you need to train your muscles enough so that they are really tired by the end of each _ . To see real benefits, make sure you are strength training 2 to 3 times a week for about 30 to 40 minutes. Typical types of strength training include: * Weight Training * Yoga * Resistance Training * Plyometrics Flexibility Training: To keep your body flexible, reducing risk of injuries and pain in your joints and muscles, you need to do flexibility training. You should always aim to stretch every muscle after any exercise routine. Typical types of flexibility training include: * Stretching * Yoga * Pilates So next time you think that yoga 5 times a week will be enough, think about what it is really doing. Is it getting your heart rate up? Are you making up your strength? Are you keeping your muscles flexible? After reading this passage, we know that _ .

Worrying about how you'll perform on a math test may actually contribute to a lower test score, US researchers said on Saturday. Math anxiety--feelings of dread and fear and avoiding math--can weaken the brain's limited amount of working capacity, a resource needed to calculate difficult math problems, said Mark Ashcrafi, a psychologist at the University of Nevada Las Vegas who studies the problem. "It turns out that math anxiety occupies a person's working memory," said Ashcraft, who spoke at the annual meeting of the American Association for the Advancement of Science in San Francisco. Ashcraft said while easy math tasks such as addition require only a small part of a person's working memory, harder calculations require much more. Worrying about math takes up a large part of a person's working memory stores as well, _ disaster for the anxious student who is taking a high-stakes test . Stress about how one does on tests like college entrance exams can make even good math students choke. "All of a sudden they start looking for the short cuts," said University of Chicago researcher Sian Beilock. Although test preparation classes can help students get over this anxiety, they are limited to students whose families can afford them. Finally, she said, "It may not be wise to rely completely on scores to predict who will succeed." While the causes of math anxiety are unknown, Ashcraft said, "People who manage to get over math anxiety have completely normal math ability." Sian Beilock points out that stress _ .

Have you seen Avatar(<<>> )? It's a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images from the movie look as if they were coming straight towards you. More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies are more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why? When we look at an object , each eye sees it at a different angle . Our eyes send the two images to our brain , and the brain puts them together. 3D technology uses two film projectors . One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can't put together the images sent to our eyes. The brain needs to work harder at "reading" the images. That makes it easier for people with eye problems to get dizzy or have headaches. A famous eye doctor said if your eyes can't focus on the same object at once, you will have trouble watching 3D movies. . When we look at an object, _ .

Researchers in the United States have developed the first wirelessly controlled device that can supply a drug directly into the body. A small chip is implanted under the skin. It contains the medicine, which it releases at preset times. The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses. A company calledMicrochips began developing the device about fifteen years ago. Last month, the company _ the results of its first successful tests in humans. The tests took place in Denmark with seven women with osteoporosis . Osteoporosis causes bones to become weak and break easily. The disorder is common among older people especially women. Many patients have to give themselves daily injection of medicine. One type of treatment requires injections for two years. The patients stop taking the medicine because of the pain and stress of the injections. As a result, only twenty-five percent of the patients will go through the entire twenty-four months of treatment. The microchip is a few centimeters long. It has small sections and each section holds a single dose of medicine. The device has to be programmed with the times to release the drug. Doctors will be able to reprogram the device from a computer or even a cell phone. For osteoporosis, the physician will program the device, and the device has the ability to release a dose at a given time, every single day. For other diseases, where the physician may want to change the dosing schedule, they will have the ability to wirelessly reprogram that dosing schedule. The seven women in the study were ages of sixty-five to seventy. The researchers say the implants were just as effective as daily injections. And they say the medicine amounts were more exact than patients often give themselves. The best title for the passage should be _ .

Passing a store, you might just step in and see if the store has received any new CDs. Once in the store, you're delighted to discover some new CDs that you must have. You could buy them later, of course, but you're already here, so why not now? In the checkout line you wonder whether to write a check or pay with a credit card. Either way would be OK, you suppose. The trouble with writing a check, though, is that you don't have much money left in your checking account. Using the credit card you won't have to pay at once, and when you do pay, you will only have to pay a little a month. So you hand the salesperson your plastic card, and that's the deal! There are a few good things about credit cards. For one thing, it's almost impossible to rent a car without a credit card. For another, they are helpful if you are in a situation where you don't have your checkbook or you have little cash with you. What are the disadvantages? One is that few people have the discipline to use their credit cards wisely. Instead, many fall into the buy-now-pay-later trap. Many become "addicted to plastic." Another disadvantage is that credit cards are more abstract than money or checks and thus contribute to our having less control over our money. Bank notes are physical things, and you have to _ your checking account every month when you pay with a check. This takes a bit of work, and although it's painful, it's more realistic. Credit cards represent the abstract, lending a certain air of unreality to the stage of managing your finances. All you do is sign your name; someone else does the math for you.

People are talking about the "new economy." It's very different from the "old economy". In the old economy, people travel to walk. They buy things in stores. They use the post office, the fax and the telephone to send information. They see people face-to-face at their jobs or in stores. People get information from newspapers, radio, television, books and libraries. In the new economy, people do business through the "net," which is a connection of millions of computers everywhere in the world. In the new economy, workers often work at home. They can get information online. They can communicate with employers and co-workers by e-mail. Businesses have "virtual stores". They are websites on which customers can see the products. Businesses can sell to customers anywhere in the world. In the new economy, people live a fast paced, convenient and colorful life. The whole world develops more quickly than before. But the new economy is a double-edge sword. Its disadvantage is also obvious. For example, the Internet has led to a huge increase in credit card cheating. Some illegal websites offer some cheap or banned goods or services. Online shoppers who enter their credit card information may never receive the goods they want to buy and their card information could even be for sale in an illegal website. So people in the new economy should be smarter and knowledgeable. The cause of the differences between the new economy and the old economy is _ .

I bent down in the shade under a sixty-foot-tall cactus , waiting for them to appear. The time was eight thirty in the morning. For seven mornings I had come to the same distant spot in the Sonoran Desert, in southern Arizona. I was here to watch the roadrunner, a small fast-running bird. I spotted two birds under a bush with red flowers. The roadrunners rushed out from under it. The birds moved rapidly on long skinny legs. Their feathers were brown and black. Their tails were seven inches long. Roadrunners use the tail for balance when running. That day, the roadrunners performed a courtship dance. They ran in wild circles. Suddenly, one stopped and stood still, its round eyes full of light. The second bird took hold of a small stick off the ground and presented it to the first, a gift serving as a symbol of their partnership. I returned to the spot each day, leaving bits of boiled chicken hoping they would return. Roadrunners eat snakes, lizards, mice, beetles, and spiders. Food is in short supply in the desert, so my offerings were welcome. The pair grew used to me. Soon after the pair finished building their nest six white eggs appeared in the nest bowl. In about three weeks, six roadrunner chicks, skin as black as coal, cried for food. Their parents brought food such as fence lizards and stink bugs. They fed their young until they were a month and a half old. Early one morning, a coyote came around, nose to the ground, for fresh bird meat. The roadrunners fearlessly drove the coyote away, but it was soon back. After three attacks the coyote went away for good, tail between its legs. I stopped watching the nest when the little roadrunners, at two months of age, were ready to live on their own. It was hard to break away from "my roadrunner family." Whenever I see a roadrunner now, rushing over the ground, I say hello to it as an old friend. What can we learn about roadrunners from the text?

Spending just a few hours a week online may make people feel more socially isolated , lonely and downhearted , according to a two-year study of nearly 100 families with the Internet. "We were surprised to find that social technology has such bad effects on social communications," the lead author, Dr. Robert Kraut of Carnegie Mellon University in Pittsburgh, Pennsylvania, said in a statement to the news. The findings suggest that "Rather than encourage students to use the Internet alone for research, teachers might give pupils online group homework to complete with classmates. Local groups might build websites that allow neighbors to discuss local affairs ." "Before the technology develops and can be really more _ , people shouldcontrol their wishes to use much of the Internet," Dr. Kraut and other experts advise. In order to control their children and encourage family activities, parents might think of putting the computer in the living room rather than in a child's room, they suggest. Dr. Kraut also suggests that when surfing on the net, especially when chatting with strangers on the net, children should not use their real names, and that they should not tell the addresses, telephone numbers to the strangers. According to the research, surfing on the Internet can make people feel more .

Have you ever imagined what human beings will look like in the future? Well, now you don't have to. According to AsapScience, a Canada-based video channel that touches on many different science topics, humans will be very different creatures 1,000 years from now. Artificial intelligence, genetic engineering and climate change will work together to change our bodies greatly, according to a video recently published by the channel. We could, for instance, develop red eyes as our DNA changes, and have darker skin because of global warming. The video painted a picture of a future world in which our bodies are part human, part machine. Nanobots, or tiny robots, will be put into our bodies, improving our abilities. "No longer will we be limited by our own physiology. We will truly become a mixture of biology and machine on the inside," says the video. Meanwhile, designer babies will cause future generations to grow into intelligent, attractive people. As global warming takes hold, humans will also be skinnier and taller, as this body shape deals with heat better. In fact, Cadell Last, a researcher at the Global Brain Institute located in Belgium, believes change may happen even faster than this. As he said in a paper recently published in Current Aging Science, mankind is already going through a major evolutionary change. In less than four decades, Last claims, we will live longer, have children in old age and need artificial intelligence to finish daily tasks. "Your 80 or 100 is going to be so radically different than your grandparents," Last said. Instead of living fast and dying young, he believes humans will live slow and die old. "The biological clock isn't going to be around forever," he added, and said that people could pause it for some time using future technology. Just a few hundred years ago, most humans were working in the fields, while nowadays more and more are getting an education. These are just predictions, and no one can be sure how human beings will evolve in the future. But with such large changes in our environments, it seems likely that we will all look very different one day. Which of the following factors could play a role in the appearance of future humans, according to the text?

Afraid that her son would be too tired, Ms. Wendy would sometimes tell the boy to skip school, but each time, Fabian would insist on going to school. "I don't like _ because when I return to school, I don't know what's going on," the 12-year-old boy explained. He suffers for SMA-a neuromuscular disease that leads to weakness in muscles-and gets around in a wheelchair. Fabian's determination to excel in his studies was evident when he was disappointed that he got a total score of 236 yesterday in his Primary School Leaving Examination. He was hoping for a score of at least 240, but his mother was full of pride. "I am happy with his results. He's very motivated," said Ms. Wendy. When Fabian was two months old, he was diagnosed with SMA. Ms. Wendy, who used to go to other homes to teach piano lessons, started teaching lessons at home so she could take care of her son. Fabian proved to be a fighter. Ms. Wendy said, " He would study every day on his own even though he was weak and his spine was already starting to curve quite badly." Fabian is also active in the Singapore Disability Sports Council, where he plays boccia , a ball sport for those who require a wheelchair due to physical disability. At just 133cm tall and weighing 14kg, he knows that he will have to rely on others all his life. "I'm afraid that when my parents grow older, they will not be able to carry me and that there will be nobody to carry me," said Fabian. "But for now, I feel lucky that I get to go out and do a lot of things that I thought I couldn't." His dreams aren't lofty either-all he want to be able to do is work and provide for his parents. "I just want to study hard so that I can be a businessman, like my dad." He is planning to apply to study at Victoria School. Which words can best describe Fabian?

Passage 1 The Information Highway is the road that links computer users to a large number of on-line services: the Web,e-mail,and software,to mention just a few. Not long ago,the Information Highway was a new road,with not many users. Now,everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems,forcing the system to close down for repair. Naturally,accidents will happen on such a crowded road,and usually victims are some files,gone forever. Then,of course,there' s Mr. Cool,with his new broad-band connection,who speeds down the highway faster than most of us can go. But don' t trick yourself:he pays for that speeding. Passage 2 Want to know more about global warming and how you can help prevent it?Doctor Herman Friedman,who is considered a leading expert on the subject,will speak at Grayson Hall next Friday. Friedman studied environmental science at three well-known universities around the world before becoming a professor in the subject. He has also traveled around the world observing environmental concerns. The gradual bleaching of the Great Barrier Reef,which came into the public eye in 2002,is his latest interest. Signed copies of his color1ful book,which was p ublished just last month,will be on sale after his talk. The Information Highway _ .

If you want to improve your child's results at school, you could do a lot worse than ensuring that they do plenty of exercise. Scientists have already shown that physical activity can make you brainier. But a team in America has used scans to show that an important part of the brain actually grows in children who are fit. These youngsters tend to be more intelligent and have better memories than those who are inactive. Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit children. They believe that encouraging children to take exercise from a very young age could help them do better at school later. Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan , a technique which provides very detailed pictures of organs and tissues in the body. They also tested the fitness levels of the children by making them run on a treadmill . The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter children. Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important implications for encouraging individuals to take part in sport from a young age. "We knew that experience and environmental factors and socioeconomic status all impact brain development," he said. "If you get some terrible genes from your parents, you can't really fix that, and it's not easy to do something about your economic status. But here's something that we can do something about." If you want to improve your children's result in school, _ .

Jack Green is 75 years old. He is not in good condition. "I think I'm ill," he tells his wife, "I feel awful. I've got a headache and I don't feel like eating." "You've put on a lot of weight recently. You should see the doctor," his wife says, "ask him how to lose weight. It's not good for your health." "OK," says Jack. He goes to see a doctor. The doctor checks his heart and weighs him. Then he says, "You are too heavy. You need to do some excercise to lose about 30 kilograms. Run two miles a day for the next 100 days. Then call and tell me your weight." A week later, the doctor receives a call from Jack. "Doctor, I ran two miles every day and I feel much better. But I have a new problem." "What's that?" asks the doctor. "I'm 14 miles away from home, and I can't find my way back." Choose the right answer according to the passage.

How you end a computer session depends on how you use the computer, your views on energy conservation , and what you have been told about how your decision will affect your investment's longevity: will frequent starting and stopping cause its circuits to burn out sooner? Rest easy, your computer is more likely to be damaged by a virus picked up from the Internet than by being turned off and on too much. They are also energyefficient: such efficiency has reached the point where most computers place themselves in sleep mode if they remain idle for a certain period of time. So your computer will likely slip into sleep mode anyway, even if you leave it on overnight. Sleep mode itself, once a pretty unreliable option--you never knew if you would be able to wake your computer without having to reboot it--has been vastly improved with newer operating systems. If you want your computer to consume as little energy as possible when not in use, shut it down. If you want it to consume zero energy, you're going to have to unplug (......) it. Your computer can be in only three states: on, sleep or off--each of which draws some level of electric current. A computer that is "on" will either be actively processing information or sitting idle, depending on whether the user is typing a document, reading an email or has stepped away briefly. The amount of wattage drawn when the computer is on varies greatly depending on whether it is a laptop or a desktop computer. The latter uses more energy because desktop power supplies are less efficient and require a separate and often larger, powerhungry monitor. It also varies based on the type of work being done: complex calculations requiring intensive processing are more powerhungry, whereas writing or Web browsing consumes far less electricity. Which of the following is NOT mentioned in the text that contributes to the different amount of energy a computer consumes?

When 18th-century scientists first came across Australia's platypus , they thought it was a trick. It is not surprising that the platypus made people confused. This funny-looking animal has feet and is a kind of warm-blooded mammal. While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus'mouth is not really like ducks'at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater. Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles , with legs on the sides of their bodies rather than under them. Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog. The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat. The following characteristics of the platypus have been described in the text EXCEPT _ .

When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie, " Homeless to Harvard: The Liz Murray Story " , shown in late April. Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member of the family who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that loss became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it. Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. _ " she wrote in her book Breaking Night. She admitted that she used envy to drive herself on. She used the benefits that come easily to others, such as a safe living environment, to encourage herself that " next to nothing could hold me down " . She finished high school in just two years and won a full scholarship to study at Harvard University . But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS. " I love my parents so much. They are drug addicts. But I never forget that they love me all the time. " Liz wants moviegoers to come away with the idea that changing your life is " as simple as making a decision " . What actually made her go towards her goal?
