It was 8:40 in the evening and I was at Starbucks -- Plaza Singapura,the place we are going to meet.I was 20 minutes before meeting time.It is not polite to be late for a date for the first time anyway.I waited,looking at the people coming and going.I was daydreaming about today's soccer match I played and started thinking about life and soccer.Life is like soccer.You never know when you are going to get hit by the ball in your face.You have to live! As I was trying to relax myself,I felt her appearance -- the smell,I can never forget.I looked up and saw her smiling and making her way towards me.She was pretty-looking and she was in fashion .I stood there watching her coming.A bright color T-shirt with a beautiful skirt.Wow,I really love girls wearing skirts.It makes them look more attractive and natural. "Sorry I am late." "No,it's OK.I am just early myself." "So what film are we going to see?" "It's OK,we will check it out later,and anyway what matters most is whom I am going to see it with,not the show." What did the man think of the girl at the first sight ?

Tests can be stressful even for the most prepared students,and,unfortunately,test anxiety can actually have a negative impact on your performance.(Just having that knowledge adds to the stress,doesn't it?)Well,the following tips can help you get through your next test with much greater ease--and likely more success! Get Enough Sleep Getting 6 hours of less can put you into what's called a sleep deficit,or lack of sufficient sleep,which can actually make you less sharp mentally and thus negatively affect your performance on tests,even if you spent those missed hours of sleep studying.So it's very important for you to get all of your studying done so you can get a good night of sleep before your big day. Study Smarter Being organized with your studies can help you keep from pulling all-nighters to get all of your studying in and blowing the test because you're exhausted.How do you study 'smarter'? Make a list of the most important things you need to learn,in order of importance,and hit the items at the top of the list first.That way,if you run out of time,you're mostly covered.Make a list of all the work you have to do,estimate how much time each item will take,and compare that with the amount of hours you have available;this will tell you if you can carefully read or just skim,how many times you can afford to revise papers,and other ways to pace yourself so you can get everything done.If you're pressed for time,it's important to learn to let go of being perfect.Oh,and turn off the TV as much as possible until your tests are behind you. Visualize Success Before you fall asleep each night,it is a great way to visualize yourself taking the tests and doing wonderfully.Detailed visualizations can help you feel like you're really experiencing something,and visualizing yourself doing well is a way to 'practice' success in a way that can actually help you perform better and feel confident.Being confident as you take your exams can keep you from choking because of the stress.Visualizations can also help you to remember facts: you can create detailed scenarios that involve the information you're trying to remember,and this can help cement the facts in your memory. Stay Calm Because stress can impair your memory,it's important to stay calm before and during tests.While that's easier said than done,there are several stress relief techniques that can help you calm down quickly whenever you feel overwhelmed.For example,breathing exercise has been shown by research to reduce test anxiety,and can be extremely effective in helping you relax and reverse your stress response in a variety of situations: just take deep breaths,expanding your belly on the inhale,and let the stress come out with your exhales. To study smarter,you'd better _ .

Have you ever dreamed of visiting a planet in the Milky Way? While the trip sounds exciting, it would take years and years to reach the place that we are going to. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years. European researchers are now doing hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel come true," said Mark Ayer of the European Space Agency last month. What seems like science fiction is not completely impossible. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out soon. A major challenge is the fact that cells can be very simple systems, but body organs are far more complex . "It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia. Just like bears and frogs, the hibernation of human beings would cause a person's metabolism to lower so they would need less energy. Medical research, however, is just half of a space flight hibernation system. There is the challenge of designing a suitable protective place to live. Such a place would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor life functions and serve the physiological needs of the hibernator. According to Ayer, the six-person Human Outer Planets Exploration Mission to Jupiter's moon Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045. , . In a hibernating situation, a person needs _ .

Something bad happened to sam this morning. He fell over and broke his nose in the school hallway. When Sam looked up, he saw his friends. "Are you OK?" They asked him. But he didn't say anything to them. He stood up and ran to the classroom quickly. Sam put his schoolbag on his desk and went out to the school hospital. On his way back to the classroom he saw his friends again. They were laughing. Sam thought they were laughing at him, so he didn't talk to them for the rest of the morning. At lunchtime, Sam's friends came up to him and asked, "How is your nose?" "Fine!" Sam shouted. "I saw you laughing at me this morning!" "We didn't. We laughed just because Jenny told us a joke," his friends said. "Well, I'm sorry. Can you _ me?" "Yes, of course. But next time you should ask us before you assume something." They looked at each other and laughed happily. They were still friends. ,,. What can we learn about from the passage?

Most humans expect to receive fair treatment. A recent study shows that monkeys may feel the same way. This is the first time scientists have seen this kind of behavior in animals. Scientists chose monkeys for the research because monkeys have close relationship with each other and they also have good teamwork. Sarah Brosnan, the leader of the research, put female monkeys in pairs. The researchers trained the monkeys to exchange a small rock with them. "That may sound simple, but not very many animals are willing to give things away." Says Brosnan. When a monkey exchanged a rock with the researcher within 60 seconds, she received a reward. Usually, the reward was a piece of cucumber. The partner of each monkey who made an exchange also received a reward. Sometimes the partner got the same reward (a piece of cucumber), but other times the partner received a better reward (a grape). The researchers were surprised at how the monkey _ to the unfair treatment. When a monkey saw her partner get better treatment, she was unhappy. The monkeys did not want to continue the test or eat the cucumbers they received. Some monkeys even threw their food at the researchers. Bronson's research suggests that monkeys do not like unfair treatment. However, as Brosnan explains, "We don't know how monkeys learn to dislike being treated unfairly. But that opens up a whole new research field." Scientists will continue their research. The monkeys in the research were trained to _ .

Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily. Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind. Since 1960 a new kind of tool has appeared. This is the silicon chip . It is smaller than a finger nail, but it can store lots of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. People will have plenty of spare time. But what will they do with it? Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now? The silicon chip is mentioned in the passage to _ .

She is a cute ,quiet girl. As a daughter, she has no secrets from her mother, who is very pleased with her. But these days she has become not so open as before. She has diary that she keeps under lock and key. Her mother cannot help worrying about her: what if she falls in love, which is too early for her age. After all, she is reaching the "dangerous time". These thoughts have caused trouble in the mother's mind. One weekend the girl came to tell her mother that she was going to the cinema with her schoolmate and would return late. This was the first time her mother agreed, and she couldn't help worrying because her daughter had never been away at night before. The mother waited till nine. She decided to go out to meet her daughter. Just at that time the noise of a car pulling up drew her to the window and---there was her daughter, waving goodbye to a boy. Her heart missed a beat. When the girl came in, the mother was watching TV, just like nothing had happened. "Mum, I'm back." "Yeah." "Sorry to be late. Still sitting up?" "Yes. Oh, that ... Who's that boy? " The daughter fell silent for some time. "Ah. It's my monitor . He gave me a lift on his way home. Mum, I'm going to bed." "All right. Go to sleep early." The next morning when the mother went to the daughter's room to do some cleaning, she found her diary left on the bed. After a few minutes' thinking, she at last opened it to the page of the night before. It reads: Mum, It's love that made you ask, but it would show your understanding of me if you hadn't. Which of the following is True according to the story ?

The Entropia Universe The Entropia Universe is a virtual world on the Internet, which seems very like our real life.It is set in a distant future and based on a planet called Calypso.Entropia was the brainchild of a group of Swedish computer lovers who decided to see if they could create a three dimensional virtual world that could be placed on the Internet.They did manage after they received the financial backing they needed. The game can be played for free, but nearly all in-game activities require personal resources that you have available to use.Although there are various activities to keep you busy on Calypso, what most people do first is to find themselves a profession, such as hunting the fierce animals on Calypso, mining the precious minerals and making tools.Then they can think about buying their virtual house or paying a visit to a virtual nightclub or doing any of the other activities that make life bearable. Entropia has its very own economy and its own currency, the PED (Project Entropia Dollars).Players move real world money into PED which they then use to pay for their life on Calypso.However, the virtual things inside Entropia do have a real value in the outside world, and careful business deals mean that players can actually make real money there.PED can be changed into dollars any time at a rate of 10PED to 1US$. What's so impressive about The Entropia Universe is the number of players; currently more than 600,000 representing over 220 countries from planet Earth.A number of players insist that it's a good way to make money.However, the reality of Entropia's economic system is that most people end up paying more than they earn and it's not uncommon to find players who are paying up to $200 a month into their PED account.This might not be the most economical way of spending one's free time.However, some people say that for them the fact that they can escape the realities of the earthbound life and become a different person with a completely different life for a few hours every week is worth the use of money, even if they don't get any interest rates on it. What can we learn about The Entropia Universe?

Dogs wag their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found. Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli with video cameras. To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time. The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners--a positive experience--their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that were required to approach. When there are no stimuli, a dog will _ .

Sharks frighten most of us, but Daniel Weaver, a shark scientist, swims with them for a living! We asked him some questions about this unusual job. So Daniel, what's it like to be a shark scientist? Well, it's a great job. I often travel to faraway places like South Africa and Fiji to study sharks. On the other hand, a shark scientist sometimes does boring desk work, such as writing reports. Also, shark scientists don't usually get paid a lot. What qualities do you need to become a shark scientist? Shark scientists need to be wise and strong. They enjoy working outdoors and they have to be cool and patient . They also have to be quite brave! So do you think it's a dangerous job? Well, sharks have up to 15 rows of sharp teeth. However, sharks hardly attack humans. There are over 350 kinds of sharks in the world and only about 10 are dangerous to us. In fact, dogs kill more people every year than sharks! Humans kill over 12 million sharks a year for food and sport! How do you become a shark scientist? A shark scientist usually studies _ or _ at university. It's also good to get some work experience in an aquarium . In my opinion, I have the best job in the world! As a shark scientist, Daniel _ .

Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors. Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them. 1. What makes us human? Just looking at your DNA won't tell you - human DNA is 99 percent _ to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on - have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity for co-operation and our trading skills are what make us unique. 2. Why do we dream? Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream. Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain. 3. Could we someday live forever? Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes and cancer, are diseases of aging, treating aging itself could be the key to extending our lives. Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism , which are all leading to the invention of drugs that can slow down the aging process. If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered. The main point of the passage is _ .

When did you last see a polar bear? On a trip to a zoo, perhaps? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in winter to swim in freezing cold water. That day, air temperature was 3degC, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island , New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group, this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February. Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter. The Polar Bears themselves are satisfied with the benefits(or advantages) of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming. The main benefits(or advantages) of cold-water swimming are probably mental . The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-year-old woman says,"When I go into the water, I pour my troubles into the ocean and let them float away ." According to the passage, some doctors believe it is true that _ .

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. According to the passage, more greenhouse gas might be given off in the future from _ .

Smart Exercise Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and prefix = st1 /ScienceUniversity, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says: "While we already know that exercise is good for the heart, exercise can literally cause physical changes in the brain." The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies, even a little movement can show big results. Margaret Barnes, a pediatrician , believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way, as they get older, children will begin to associate physical activity with higher learning," says Margaret. Older people can beef uptheir brains as well.CornellUniversitystudied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for infants, exercise for older people should involve some complexity. Learning some new skills or motions helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood. And your brain can benefit from as little as two to three hours of exercise a week. Margaret Barnes thinks that a lack of movement in infancy can

Today, when there are many top graduates looking for top jobs, graduates can differentiate themselves by obtaining a double major or even a double degree. Increasingly, employers are looking for individuals who are not only competent and intelligent, but who have different skill sets and who are knowledgeable in many areas. Part of the appeal to employers is that your extra work demonstrates a willingness to take on difficult tasks. Additionally, if your majors overlap , you are able to show potential employers that you have both _ and depth of knowledge. By studying for a double major, although you will be studying for only one degree, you will be focusing on two related and integrated subjects that complement each other. Classes overlap between the majors, meaning fewer classes are required than with a double degree, so it is easier to finish within four years. In contrast, with the more rigorous double degree, you will be studying for two different degrees in two completely different areas of study. Although pursuing such a course of study allows students to complete two wholly separate degrees in less time than if they were to earn them separately, many strong students still find it incredibly difficult to complete in four or five years. If you are committed to a double major/degree, it is wise to do a little bit of planning. Some students try to find two courses of studies that are related, while others seek to round out their academic studies by choosing two completely unrelated fields. For double majors, common pairings include: (i) economics and a foreign language; (ii) political science or government and journalism; (iii) economics and psychology. For double degrees, common pairings include: (i) engineering and a business program such as finance or accounting; (ii) engineering and economics. To obtain a double major, you _ .

Most nutrition education isn't very effective. People know that an apple is better than a Snickers bar, but they often eat the Snickers bar anyway. After conducting hundreds of studies on the psychology of how and why we eat, I've seen that it's good to understand nutrition, but it's much better to change your eating environment. Doing so can help you make better choices without even thinking about it. Part 1 We all know children can be stubbornly habitual in what they want to eat. If kids had French fries yesterday, they want them again today. We came up with a simple way to interrupt this default. Instead of asking kids what they want, what if we ask them about someone they admire? We studied this with elementary school-aged children one summer. We treated 22 kids to apple slices or fries at a fast-food restaurant. The first week, 20 of them ordered French fries, and two ordered apple slices. But the next week, we asked, "What would Batman eat: apple slices or French fries?" After they answered for Batman, we asked them what they wanted. This time, the number of kids who ordered apple slices jumped from two to ten-- almost half of them. If you ask yourself before deciding between the salad and the cheesy bacon fries, "What would my role model choose?" you'll be a lot less tempted. Thinking about what a well-liked person would do makes us _ . Part 2 If we knew what a skinny person's kitchen looked like, we could set up our own kitchens in a similar way. Once we got into people's homes, we took pictures of everything: their dishes, sinks, refrigerator shelves, counters, snacks, pet-food dishes, tables, lighting -- even random items held up by magnets on their refrigerators. Then we spent eight months coding these kitchens to see what thin people do differently. We wondered if big kitchens turn us into big people. But it turns out that kitchen size isn't the problem. It's what you see in the kitchen. The average woman who kept potato chips on the counter weighed eight pounds more than her neighbor who didn't. "In sight, in stomach." We eat what we see, not what we don't. What's the writer's purpose of writing this passage?

Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm . Snakes can swallow things that are bigger around than they themselves are. This is possible because the jawbones are loosely joined, and the mouth can stretch to make room for a fat animal. The snake's slim body stretches to make space for the animal when it is inside. Many snakes eat birds' eggs or frogs . Others eat pests , mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts. Snakes may do some valuable work by _

"I usually put my mobile phone in my bag, and I often feel like it is ringing when there actually is no phone call. Now I always want to keep it in my hand, being afraid that I might miss important calls or messages," Miss Liu tells her doctor. Miss Gu, a news worker, has to take her mobile phone with her all the time so as not to miss any calls from her office or readers. Gradually, she started to experience a great "panic" about her mobile phone. "Every night when I'm about to fall asleep, I often wake up with a start, feeling that my phone is ringing. Although I'm sure that I have turned it off, I still feel that it is ringing, clearly." The above phenomenon is what we call "mobile-phone acouasm ". The mobile phone has now become a "new organ" in a white collar's daily life, and "mobile-phone acouasm" has become a common phenomenon among office workers. According to a report of China Youth Daily, "mobile-phone acouasm " most likely results from people's dependency on hi-tech products. It is associated with certain professions, such as salesmen, consultants and journalists. They use mobile phones almost continuously. Constantly being in the "stand-by" mode, the strong psychological tension gives them acouasm. Meanwhile, a large number of this year's graduates are joining the family of acouasm suffers due to the hard job-hunting experience. "You know that the rings are not from your phone, but you always take it out and have a look. This is subconscious from your body sending you a signal, telling you that you must take a break to reduce your pressure," Professor Sun Li from Huadong Normal University explains. There are many ways to solve the problem. The professor says that the key is to deal with pressure from work. "This is just a kind of self-protection"; the most important thing is to find out the source of your pressure. And then take part in some activities that are not related to your work. You can do anything that can relax your body and mind. What is the most important measure to deal with "mobile-phone acouasm " ?

Can dolphins talk? Maybe they can't talk with words, but they talk with sounds. They show their feelings with sounds. Dolphins travel in a group. We call a group of fish a "school". They don't study, but they travel together. Dolphins talk to the other dolphins in the school. They give information. They tell when they are happy or sad or afraid. They say "welcome"when a dolphin comes back to the school. They talk when they play. They make a few sounds above water. They make many more sounds under water. People cannot hear these sounds because they are very, very high. Scientists make tapes of the sounds and study them. Sometimes people catch a dolphin for a large aquarium .

Teaching your child to cook is not hard; the hard part could be getting them out of the kitchen. When you are teaching them, remember to stress safety and cleanliness, after all these are skills they will need for many years into the future. Start by finding simple no-cook recipes. A salad or other no-cook recipe is an ideal way to start. Show your child how to hold, and cut with knives. Make sure they know how to wash everything in hot soapy water as they use it, so that it becomes a habit that is part of the process and not an extra chore to do after they have finished. If possible, find one of the good children's cookbooks that are available. Many of these have simple recipes that demonstrate the basic cooking terms such as chop, mix, and stir. When it is practical, you may as well have your child help you prepare meals. Even a small child can get bowls out, pour, and start learning to measure. A two- year -old child can stir a batter , or taste the results. Allow your older child to find a recipe that they think sounds nice. Go over the recipe with them as you discuss the steps needed, and how to adjust any ingredients to match your budget, and family preferences. When you go shopping, have your child help find the necessary ingredients for their 'special' recipe. When it is time to make the recipe, allow them to do as much as possible, only helping out if asked or when they run into trouble. Be sure to praise their efforts even if they are not perfect. After the results are gone, talk about any problems, and see if there is a solution. Most children like to cook, and if they are part of deciding what to cook, as well as the preparation they will be well on the way to being good cooks. The author wants to say in the passage that _ .

A boy was born to a couple after eleven years of marriage. They were a loving couple and loved the boy very much. When the boy was around two years old, one morning the husband saw a medicine bottle open. He was late for work so he asked the wife to cap the bottle and keep it in the cupboard. The mother, preoccupied in the kitchen, totally forgot the matter. The boy saw the bottle and playfully went to the bottle and, fascinated with its color, drank it all. It happened to be a poisonous medicine meant for adults in small dosages . When the child fell down, the mother hurried him to the hospital, where he died. The mother was shocked. She was terrified how to face her husband. When the father came to the hospital and saw the dead child, he looked at his wife and uttered just four words. The husband just said 'I am with you, Darling'. The husband's totally unexpected reaction is active behavior. The child is dead. He can never be brought back to life. There is no point in finding fault with the mother. Besides, if he had taken time to keep the bottle away, this would not have happened. No point in attaching blame. She had also lost her only child. What she needed at that moment was comfort and sympathy from the husband. That is what he gave her. If everyone can look at life with this kind of viewpoint, there would be much fewer problems in the world. Take off all your envies, unforgiveness, selfishness, and fears and you will find things are actually not as difficult as you think. Sometimes we spend time asking who is responsible or whom to blame, whether in a relationship, in a job or with the people we know. By this way we miss out some warmth in human relationship.

Living abroad to study can certainly be an interesting experience but is that alone a good enough reason for spending years far away from home? To make the experience truly worthwhile, there has to be a goal behind the decision to study abroad. This may be a wish to perfect language skills in a foreign language environment, or a clever move in your career development. You must also consider the costs, not just of living and studying abroad, but of applying. Most universities now charge application fees for international students. If after considering these points you are sure that you want to apply to study abroad, your next step is to choose the right programme of studies. Research your choices and select carefully. You must do your homework well. Most universities have information online but you can also email and ask them to send you more details. You can find a lot of information on school ranking from education websites. But read carefully. Different universities emphasize different strengths. Don't just think about the university's reputation ; look for the most suitable for your goals. Next, you must deal with a large pile of paperwork. This involves filling in application form, preparing your school records, and getting reference letters. Reading the instructions and requirements of the universities carefully is of great importance. Sadly, many fine applicants get kicked out in the first round, simply because they don't follow the application procedure properly. Money is another important consideration. Some scholarships are provided by governments, others by schools and colleges. This information, again, can be found on the Internet. If you find a scholarship that is suitable for you, follow the application procedure carefully; the earlier you apply, the better your chance of getting it. According to the article, studying abroad is truly worthwhile because _ .

On Tuesday,a new study published in the American Heart Association's journal Circulation:Heart Failure revealed that women who ate five or more dishes of baked fish a month had a thirty percent lower risk of heart failure in comparison to women who ate less than one dish a month. Researchers examined the diets of 84,493 women,whose ages ranged from 50 to 79.The women who had eaten lots of baked fish like salmon ,were more healthy than those who mostly ate tuna or white fish. Eating baked fish also appeared to provide a protection against high blood pressure. The study also found that those women who ate more baked fish were likely to have a lower weight,exercise more and eat more fruits and vegetables in comparison to those who ate fried fish. Researchers noted that past research had discovered the fatty acids in fish probably decreased the risk of high blood pressure by improving blood pressure along with heart and blood functioning. This study showed the link between eating fish and heart failure risk but it was not designed to show cause and effect. This study also showed that just by eating one dish of fried fish a week led to a 49% greater risk of heart failure,and eating fried fish led to lower fiber intake and higher calorie intake. The American Heart Association suggested eating a minimum of two dishes of fish especially fatty fish each week. Compared to the women who ate fried fish those who ate more baked fish could _ .

Stockholm's street magazine sellers no longer only take cash -- they now take cards too. "More and more sellers were telling us that people wanted our magazine but weren't carrying cash," says Pia Stolt, the magazine's publisher. "So with the help of a local computer company, we came up with a way to accept payment electronically. "We didn't know how it would turn out, or whether people would be unwilling to give the credit card information to a stranger on the street," says Stolt, "but the results have been great--sales are up 59%." "Swedes are pretty trusting and we're used to taking up new technology so this was the perfect solution," adds Stolt. "The cashless society campaign we're seeing in Sweden is definitely a good move as far as we are concerned--it's unstoppable." Banks and stores invested heavily in card payment systems in the 1990s and now local consumers are using them in huge numbers. Today, four out of five purchases are made electronically in Sweden and going totally cash-free is the next step. Sweden's public transport system has already been cashless for several years, after local public transport workers complained that handling cash had become dangerous. "Bus drivers were getting attacked for their money so Sweden banned cash on public transport," says Arn Arvidsson, the president of Cashless, an organization supporting the move to a cash-free society. "There were also a number of bank robberies, so four years ago, the banks began to move away from cash. Now, all of Sweden's big banks operate cash free wherever possible, and the number of bank robberies is at a 30-year low." There is, however, concern about how well Sweden's 1.8 million pensioners--out of a total population of 10 million--will adapt. "A lot of elderly people feel excluded," says Johanna Hallen of the Swedish National Pensioners' Organization. "Only 50% of older people use cash cards regularly and 7% never use cash cards. So we want the government to take things slowly." The digital payment revolution is also a challenge for tourists, who need pre-paid tickets or a Swedish mobile to catch a bus in the capital. "There's a worry about crime and theft as well," says Arvidsson. "Figures show that computer-related credit card crime has almost doubled in the last decade." Which of the following about Sweden is true according to the passage?

A global positioning system(GPS)service is aiding the elderly in the Panlong district of Kunming,capital of Southwest China's Yunnan province. The telecommunications service provider,with the support o,f the local govemment,started the GPS tracking service in January to help the elderly,especially those with Alzheimer's disease,a condition that slowly destroys memory. Huang Haiying,an employee with a local telecommunications company,told China Daily that with the GPS devices ,the people who look after the elderly can quickly find their positions either online or by ca l l ing the service center in case ot emergencles. The system is also connected to the police,hospitals,fire services and community service centers to ensure that the elderly get quick and proper help,Huang said. Experts said that this service could improve the quality of life for thousands of elderly people with Alzheimer's,their families and those who look after them. Hundreds of people have already been helped by the service this year,Huang said. Huang said that the system has about 1 0,000 subscribers and she expects that number to grow 1 0 times over the next three years.A user pays 25 yuan($4)each month for the service.A family with an income below the local poverty line can get a 10 yuan subsidy evcry month from the government. The local government has spent more than 2 million yuan to subsidize the service to date. Rao Yuehui,director of the Panlong civil affairs department,said that about 90,000 people,or 15.4 percent of the district'S population,are more than.60 years old.

(Published March 30, 2011)Albert Einstein's Theory of Relativity might have a few mistakes--and Jake Barnett has set out to prove it. Between attending college classes at Indiana University-Purdue University Indianapolis (IUPUI) and tutoring his fellow students, Jake is also working on a new theory about the creation of the universe. He happens to be 12 years old. From an early age, Jake showed an extraordinary interest in stars. When he was 3, his parents took him to a space observatory. He tried to learn as much as he could about astronomy. Jake's IQ measured remarkably high at 170. As a baby, Jake was found out with Asperser's syndrome, a form of autism . Autism causes difficulties in communication and social abilities. People with autism may also have strong interests--like Jake's interest in the stars at a young age. The symptoms of autism can range from mild to extremely severe. Asperser's is one of the milder forms of autism. Sometimes people with Asperser's, like Jake, develop extremely advanced skills in science, music or art. When Jake was in elementary school, his parents worried that the effects of his Asperser's were worsening. He became quiet. _ So a doctor recommended that Jake's parents let him study more advanced subjects, like math and physics. Jake's mother asked an astronomy professor to let Jake sit in on his class. Now, Jake studies advanced sciences like electromagnetic physics at IUPUI. But Jake thinks it's important to have a normal life too. He likes to play Guitar Hero with his friends and watch science fiction movies. He also enjoys playing classical music on the piano.But for Jake, studying physics is the most important thing. Jake's professor, John Ross, is working on getting a large sum of money for him to do research at the university. Doctors have said Jake's autism symptoms have lessened over time. Still, Jake proudly refers to himself as an "Aspy", or someone with Asperser's. In an interview with his university student newspaper, he said, "I think the autism is the reason I'm even at IUPUI." In the eyes of Jake, autism is something _ .

Some students who took the International English Language Testing System(IELTS) exam in August and September, 2015 have had their results"withheld permanently", sending a strong signal that the examiners intend to stamp out cheating, some senior language tutors said. Yang Yuting, chief language training tutor at Amber Education, an overseas education consulting agency, said there have been a few cases in which candidates' IELTS results were canceled in recent years, leaving the students with no qualification but this is the first time he has heard that results, including those of some of his students, were"withheld permanently", meaning IELTS will not give the students their results, nor will they give them to others. Wang Xin, a senior student at the Communication University of China in Beijing, took an IELTS test on August 1 and the results were due within 10 working days. But she was then informed that her results were undergoing routine checks. Soon after that, she received an e-mail telling her that"a decision has been made to withhold this result permanently"and stating that Wang had"breached IELTS test rules and regulations". A number of students who took the test during the past two months in cities including Nanjing, Changsha and Guangzhou, have had the same experience. Many test takers said they were confused because they didn't know how they had breached the rules and regulations. IELTS authorities said in an e-mail toChinaDailythat IELTS takes the responsibility of providing test results very seriously. Results are only withheld in cases where there is strong evidence to suggest that the candidates have not observed IELTS regulations."In these cases, we are unable to guarantee that their result is a true reflection of their English language skills,"they said in the e-mail, although they gave no figures of how many students were involved."We regret any inconvenience this may cause, but these measures are essential to protect the value of the results for more than 2.5 million test takers every year. Hundreds of thousands of people take IELTS in China every year and the number of results which are permanently withheld is a tiny proportion ,"they said. Hu Min, president ofNew Channel International Education Group, an English-language tutorial agency in China, said a major cause of results being withheld might be an extreme imbalance in performance levels in the four sections of the test."For example, if a student scores very high in the reading and listening sections while performing poorly in writing and speaking, IELTS authorities may suspect that the test taker has memorized the reading and listening questions -- a practice that is very popular among Chinese test takers,"he said."IELTS authorities discourage such a practice and would determine that the scores can't reflect the real English level if test takers do so." Students whose results were withheld were .

Two new studies suggest that modern running shoes could increase the risk of injuries to runners. One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine . Sometimes they wore running shoes. Other times they ran barefoot . Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study. They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels. The study appeared in the official scientific journal of The American Academy of Physical Medicine. The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland. They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running. Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel. Harvard's Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings. But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured. The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website. What is the writer's attitude towards the use of the modern running shoes?

At least eight babies in East China'sprefix = st1 /AnhuiProvincehave died since last year. they died of serious deficiency disease which happened to them because of fake milk powders. More than 100 other babies in Fuyang, mostly between three and five months old, are still in poor nutrition after drinking different kinds of cheap milk powders produced in North China's Inner Mongolia Autonomous Region, Northeast China's Heilongjiang Province and Beijing. The baby victims were born healthy, but they became thinner and thinner, and had large heads for their bodies after fake milk powders were fed to them. "My girl, the first child of mine, died when she was only four months old after drinking the 'Haobaobei'milk powder."said Zhang Linwei, a 32-year-old villager of the Wangzhuang Village in Fuyang. Zhang found that his daughter got ill after the girl didn't want to drink the milk powder any more half a month before. "Before that , I though my daughter's face was becoming fatter and fatter because she was fed well and grew fast."the baby's father said. The girl died nine days later after she was sent to hospital and all of the family's savings were spent on her medical treatment. "It is like a terrible dream. I never thought that my baby would _ like this ."he said. Zhang said he tried to telephone and write to the producer of the milk powder by the address on the packing bag but never made it. "The fake milk powders only have 5-6 per cent protein and the lowest is has only 1 per cent. For babies, drinking such fake milk powder is no different from drinking water,"Zhang Fangjun, said a medical expert with the Fuyang People's Hospital. "Such so-called milk powders cannot afford any nutrition for babies' growth," Zhang said. Zhang Linwei_.

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." All the following factors that have some influence on one's brain are mentioned EXCEPT _ .

You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that's about a liter of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough. After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month? The photograph of me taken the day I started this trial demonstrates perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster . It looks dead. Even my lips look shriveled . This is all classic evidence of poor hydration, apparently. Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste. Not drinking enough means all these functions becomes damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing. Why did the author decide to drink the recommended amount of water?

Famous as "the king of chefs and the chef of kings," Auguste Escoffier helped raise the position of cooking from a laborer's task to an artist's job. Escoffier was born on October 28, 1846, in the small village of Villeneuve-Loubet, near Nice, France. Among the key figures in the boy's life was his father, who worked primarily as a blacksmith . His grandmother, an enthusiastic cook, was perhaps more responsible than anyone for introducing the boy to an appreciation of the delights of cooking. Young Escoffier attended the local school until age 12, upon which time his father thought it necessary that the boy learn a trade. In school he had shown a talent for drawing, yet he was told to regard this art only as a hobby, and to find his career in a more practical profession. Thus his father took him to Nice in 1859, where he would work as an apprentice in his uncle's restaurant, the respectable Le Restaurant Francais. At Le Restaurant Francais, Escoffier was not treated as the close relative of the boss. Rather, he experienced a classically demanding apprenticeship. For this strictness of training he would later, in his memoirs , express gratefulness. During this time Escoffier also attended night school, and had to deal with his studies as well as the demands of a promising career. When Escoffier was 19 and had taken on yet more responsibilities in his uncle's restaurant, a customer recognized his skills and offered him work in Paris. This was the owner of Le Petit Moulin Rouge, one of the finest restaurants in Paris, where Escoffier was to become a sous-chef, ranking below the head chef. After three years in this position, he rose to the level of head chef, wearing the respected chef's hat. Which of the following can best describe Escoffier?

Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world. So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls ? Why don't we use them for collecting energy? The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work? The Solar Road Panels will contain embedded LEDs which "paint" the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour ahead. The road will be able to sense wildlife on the road and can warn drivers to "slow down". There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving. Replacing asphalt roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips. We just can't wait to see more of these roads all over the world in the near future. What is the text mainly about?

The street food stands are very popular in Korea . They take their name from the two kinds of hot foods they sell : Dukbokgi and Odeng . Dukbokgi is a spicy hot food made of rice cakes and some vegetables . These rice cakes are finger-shaped . They are white , and they are about ten centimeters in length . They are mixed with sliced vegetables in a pan with a spicy red dressing . Fifteen minutes later , they are ready to eat . Odeng is made of ground fish . It comes in many shapes : some are square , others are round , and still others are stick style . You can buy big or small ones . At these food stands , you can also eat Odeng , which has been boiled in a pot . It is served on a long stick so can eat it easily . The food sold at these stands is not expensive , compared to what other foods in Korea cost . Each Dukbokgi and Odeng costs about twenty to fifty cents , depending on the owner . Each food stand has its own recipes for its food ; for example , some like to add sugar or other special ingredients in the food . Usually , there is just one owner , but if the food stand is big , there may be two or three owners .

Astronomers recently found another ring around the planet Saturn -- and it's the biggest one yet. This newly discovered ring stretches about 15 million miles across, which makes a loop big enough to fit a billion Earths inside. It may be even bigger and reach 22 million miles across at its diameter . Saturn's new ring is now the biggest known ring in the solar system. This ring, like Saturn's other rings, is not one solid piece of rock. Instead, it is made up of millions or billions of tiny rocks that orbit the planet all together and give the appearance of a unified ring. Unlike the more visible rings, however, this big one is mysterious -- the pieces are far apart, and the ring cannot be seen from the surface of the Earth. If all the pieces were stuck together, they'd be slightly bigger than a rock a half-mile wide. Astronomers suspect that the newly discovered ring gets its material from Saturn's outermost moon, Phoebe. For example, the dust in the ring circles Saturn in the same path and the same direction as Phoebe. Plus, the surface of Phoebe is marked with holes and places where rock has been knocked away, the result of collisions between Phoebe and other moons and rocks. These collisions could have sent dust out into space to become part of the big ring. The discovery of the ring could help explain other mysteries surrounding Saturn and its dozens of moons. The moon called Iapetus, for example, is two-toned: one side is gray; the other more reddish. Iapetus is within the newly discovered ring, but it orbits in the opposite direction. As a result, some researchers say, debris from the ring may have coated and color1ed one side of Iapetus as it moved through space, and left the other side alone. "The cause of Iapetus' strange color1 distribution ... has been a puzzle that now seems solved," said Joseph Burns, a scientist. But not everyone agrees. Some think the ring alone may not be able to explain Iapetus' funny color1ing. Which of the following is NOT true about the newly found ring?

Most of us probably live without vegetables, but a world without chocolate? Now that would be hard! According to chocolate makers it could happen if we don't act soon. There are two main causes of the chocolate shortage --- chocolate's growing popularity and less production of cocoa, the plant from which chocolate is made. With more and more people in India and China loving chocolate, not much can be done about the first cause. Therefore, the only thing we can do is to increase cocoa production. However, new plant diseases and little rain in Ivory Coast and Ghana, the world's largest producers, have reduced cocoa production by 40 percent in the past 10 years. What's worse, many cocoa farmers in Africa and other cocoa-producing countries like Indonesia and Venezuela are changing to easier-to-grow crops such as corn or rubber. This way, the farmers can make more money. To prevent more farmers from changing, researchers at the newly opened International Cocoa Control Centre, in the UK, are trying to create new cocoa plants that are stronger and faster growing. But first they must make sure the new plants are safe to grow. This takes a long time. First, each new plant is stored at the Control Centre for six months to make sure it is healthy. It is then planted in the Centre's fields, studied and tested for another two years. Only after scientists are certain that they're disease-free, will the plants be sent to farmers in West Africa or wherever else they are needed. To create new stronger types of cocoa, scientists at the Centre are combining the best parts from different cocoa plants. Though the world is facing a serious chocolate shortage, there is now hope! Cocoa farmers are choosing to grow rubber and corn because these crops _ .

A MILLION people on Mars within 100 years. This is the brave vision of Elon Musk, the founder of the space technology company SpaceX. "We need to be laser-focused on becoming a multi-planet civilization. That's the next step," he said in a recent interview with Aeon magazine. Musk expects to see about 80,000 people living on Mars by 2040. It's all about protecting the human race from extinction, according to Musk. The Earth has always been a ticking time bomb. As the sun begins to die, it will grow bigger, becoming what is known as a Red Giant. In 500 million years, the sun will have become large enough to kill off any plant and animal life on Earth, according to US scientist Edward Guinan. In a billion years, the Earth will have become a hot planet with little or no water. The brave dream of getting the human race to Mars is not only Musk's; others have made plans, too. A Dutch entrepreneur set up the Mars One foundation in 2011, hoping to be the first project to put humans on Mars. It received over 200,000 applications to become part of the first group of astronauts to go there. According to Mars One, "human settlement on Mars is possible with existing technologies." Water, food, energy, and oxygen are needed for life anywhere. According to Mars One, water that was still in the Martian soil would be boiled and taken out. By using a process called "electrolysis", astronauts could split water into hydrogen and oxygen for breathing. Astronauts on the International Space Station have already done similar things. Food can also be grown in space. Certain plants such as lettuce and onions can be grown using LED light for different color spectrums and much less heat. NASA has been researching this to prepare for visiting Mars. But how will people get there? The Mars One project plans to use SpaceX's Dragon capsule as part of its mission. But it is rumored that Musk already has a design in mind for a giant spaceship. He calls it the Mars Colonial Transporter. We can infer from the article that the author is _ human settlements on Mars.

One of our biggest fears nowadays is that our kids might some day get lost in a "sea of technology"rather than experiencing the natural world.Fear-producing TV and computer games are leading to a serious disconnect between kids and the great outdoors,which will change the wild places of the world,its creatures and human health for the worse,unless adults get working on child's play. Each of us has a place in nature we go sometimes,even if it was torn down.We cannot be the last generation to have that place.At this rate,kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes."If the decline in parks use continues across North America,who will defend parks against encroachment ?"asks Richard Louv,author ofLast Child in the Woods. Without having a nature experience,kids can turn out just fine,but they are missing out a huge enrichment of their lives.That applies to everything from their physical health and mental health,to stress levels,creativity and cognitive skills.Experts predict modern kids will have poorer health than their parents--and they say a lack of outside play is surely part of it:research suggests that kids do better academically in schools with a nature component and that play in nature fosters leadership by the smartest,not by the toughest.Even a tiny outdoor experience can create wonder in a child.The three-year-old turning over his first rock realizes he is not alone in the world.A clump of trees on the roadside can be the whole universe in his eyes.We really need to value that more. Kids are not to blame.They are over-protected and frightened.It is dangerous out there from time to time,but repetitive stress from computers is replacing breaking an arm as a childhood rite of passage. Everyone from developers,to schools and outdoors' citizens,should help regain for our kids some of the freedom and joy of exploring,taking friendship in fields and woods that cement love,respect and need for the landscape.As parents,we should devote some of our energies to taking our kids into nature.This could yet be our greatest cause.

New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight. Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico. The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals. Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death. "Because we'd actually already read a lot of this literature and realized it was likely that mortality rates for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn't seem to differ from normal weight." But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese. The study has raised new questions about "body mass index," or BMI. This is a measurement of body fat as a ratio of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases. Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular. Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes . According to the new findings, the researchers found that _ .

According to a survey, only 4% of the people in the world are left-handed. Why? One theory centers on the two halves of the brain. For example, the left half and the right half, each of which functions differently. Medical science believes that the left half of the brain dominates over the right half. The foundation of this theory is the fact that nerves from the brain cross over at neck-level to the opposite side of the body, and nerves from the other side of the brain reciprocate . The end result is that the opposite sides of the body are controlled by the opposite sides of the brain. The dominant left half of the brain, which kindly supplies the right half of the body, theoretically makes it more skillful in reading, writing, speaking, and working, and makes most people right-handed. Lefties, however, whose right half of the brain dominates, work best with the left side of their bodies. Theory number two focuses on the _ nature of the body. Examples of the asymmetry, which flows from head to toe, are that the right side of our faces differs slightly from the left, that our legs differ in strength, or that our feet vary in size. One aspect of this asymmetry is that for most people the right hand is stronger than the left. There is no doubt that all exist in a "right-handed society", which produces most basics, including scissors, doorknobs, locks, screwdrivers, automobiles, buttons on clothing, and musical instruments for the 96%. Left-handed people make up for the unfairness by being members of an elite society, which includes many of the greatest geniuses, including Michelangelo and Leonardo da Vinci. Which of the words or phrases is closest in meaning to the word "asymmetrical"?

An apprenticeship is a form of on-the-job training that combines workplace experience and classroom learning. It can last anywhere from one to six years, but four years is typical for most. An apprentice spends most of the time in a workplace environment learning the practical skills of a career from a journeyman--someone who has done the job for many years. The rest of the apprentice's time is spent in a classroom environment learning the theoretical skills the career requires. Being an apprentice is a full-time undertaking. One of the advantages of apprenticeship is that it does not cost apprentices anything. The companies that hire them pay for school. What's more, it offers apprentices an "earn while you learn" opportunity. They usually start out at half the pay of a journeyman, and the pay increases gradually as they move further along in the job and studies. Near the end of the apprenticeship, their wages are usually 90 percent of what a journeyman would receive. Apprenticeship also pays off for employers. It can offer employers a pool of well-trained workers to draw from. Despite the advantages, apprentices are usually required to work during the day and attend classes at night, which leaves little time for anything else. Sometimes, they might be laid off if business for the employers is slow. Once they have completed the apprenticeship and become journeymen, they receive a nationally recognized and portable certification and their pay also increases again. Some journeymen continue employment with the companies they apprenticed with; others go onto different companies or become self-employed contractors. Which of the following is NOT the advantage of apprenticeship?
|
[
"It saves lots of money for apprentices to learn the skills.",
"It brings apprentices some earnings before they get a job.",
"It allows apprentices to earn the same wages as journeymen.",
"It helps employers take on more qualified workers."

In jokes, the chicken only crosses the road. In Australia,cane toads use roads to travel. A new study finds that Cane toads are using roads to spread across the continent. They take shelter overnight close to the opencorridors , and then hit the road each evening in their damaging way. Cane toads were brought into Australia from Hawaii in 1935 to control the spread ofbeetles that were destroying Australia's sugar cane crop. _ are now moving into new places at the speed of 30 miles a year. Toads can grow as large as dinner plates and can weigh up to 4.5 pounds. Their heads and backsides are covered with rows ofwarts . They are known to kill snakes, lizards and other animals, including pet dogs. They have no natural enemy in Australia. According to a research, toads make slower progress through thick plants than along open spaces and they hop alongside roads and fences whenever possible. Toads use long corridors that are well-suited for them to travel long distances. Another study recently found that toads haveevolved longer legs in recent years and that this is also helping them in their spread. Efforts to kill toads have been largely unsuccessful, although scientists tried their best. Another new finding suggests ways to slow down its population. For example, roadside borders can be changed to make them less attractive to toads, or allowing thick plants to grow along the sides of highways, thus forcing toads onto the road of themselves. At first, cane toads were brought to Australia to _ .

What can you do on the Internet? Many of us like to read the news, buy things and play games. Some students now have a new use for the Internet - helping them with their homework. Tina, 14, from Shenzhen, Guangdong, often searches online for the answers to her math problems. She said sometimes she and even her parents don't know the answers to the problems, so she has to turn to the Internet. "I can see how other people work out these problems and learn from them," Tina said. "It's easy and saves time." But not all the students welcome this. Leo, 15, from Hangzhou, Zhejiang, thinks it may make students stop thinking. "We should think over the problems first. Simply copying the answers won't improve our abilities. " he said. In the eyes of Wang Zhaoming, a Shanghai teacher, the success of all this is down to the students. If they use the Internet properly , it could be a good tool for study, Wang said. "Students should first think about the problems by themselves. As for the online answers, they should choose the best among different ones. The most important thing is to know the logic behind the answers," he said. "Don't be shy to ask teachers and classmates the next day if you don't understand the answer." According to the passage, it's a new use for students to _ on the Internet.

Researchers in over 80 nations are taking part in a project to conduct a decade-long census of sea life. Scientists presented some of their findings at a recent conference as the project neared its completion. In deep icy waters under Antarctica, scientists found bulbous tunicates, an underground animal, and many newly-discovered creatures believed to be related to starfish and other marine creatures. Elsewhere in the world's oceans, they have recently discovered many kinds of underwater life forms new to science. It is all part of a research effort called the Census of Marine Life. "There are about 2,000 scientists worldwide involved," said Bob Gagosian, President, CEO of the Consortium for Ocean Leadership. Gagosian helps manage the project. "Everywhere they've gone they've found new things," he says. "The ocean basically is unexplored from the point of view of marine living things." Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration routes and to discover places where sea life gathers. According to Ron O'Dor, a senior scientist with the Census of Marine Life, knowledge of life on the ocean floor is especially limited. "90% of all the information we have is from the top hundred meters of the ocean," O'Dor states. And he says the sea floor is, on average, at a depth of 4, 000 meters. And so, as some machines dive far below what people have previously seen, scientists are discovering new species of plants, animals and living things. Since the census project began, more than 5,300 new marine animals have been found. Ocean researchers say they hope to catalogue 230,000 species during the census --which some say is only a small part of all the creatures living in the sea. Why do the researchers place small markers on many marine creatures?

The first day our professor challenged us to get to know someone we didn't know. I looked around when a gentle hand touched my shoulder. I turned around to find a wrinkled, little old lady smiling at me. She said, "Hi, handsome. My name is Rose. I'm 87. Can I give you a hug?" I laughed, "Of course you may!" and she gave me a giant squeeze. "Why are you in college at such a young, innocent age?" I asked. She jokingly replied, "I'm here to meet a rich husband, get married, and have a couple of children." "No seriously," I said. "I want to realize my dream!" she told me. Over the course of the year, Rose became a campus icon and everyone liked to listen to this "time machine". At the end of the semester we invited Rose to speak at our football banquet and I'll never forget what she taught us. "There is a huge difference between growing older and growing up. If you are 19 and lie in bed for one full year and don't do one productive thing, you will turn 20. If I am 87 and stay in bed for a year and never do anything I will turn 88. We have less time to live on. Anybody can grow older. That doesn't take any talent or ability. The idea is to grow up by always finding opportunity in change. The elderly usually don't have regrets for what we did, but rather for things we did not do." At the year's end, Rose finished the college degree she had dreamed about all those years. One week after graduation Rose died peacefully in her sleep. Over 2,000 students attended her funeral honoring the wonderful woman who taught us such an important message. According to Rose, growing up is different from growing older because _ .

As I grew older, my dad and I grew further apart.We always had totally different opinions.He thought that college was a waste of time,but for me it was important to finish college.He wanted me to work my way to the top as he had done in his field,but l wanted a different life.There was a time when we did not talk with each other. A few months ago, I heard that my 84-year-old dad was in poor health.When he called and asked whether I could move from Colorado back to Tennessee to help him,I knew he was seriously ill.I am his only child and so it was time to meet my father's requirement. Two weeks after moving back,we bought a boat and started fishing again.Fishing was one of the few things that we did while l was young and that we both enjoyed.It is strange but true that as we are fishing we are able to put things that have kept us apart for so many years behind us.We are able to talk about things that we have never talked about before.Fishing has been healing the old wounds that have kept us apart. It is not important how many fish we catch.It is about enjoying the relationship that we have not had for years.I'm 62 and he is 84.When we are on the lake fishing,it is like two kids enjoying life.It is far better to find a way to put the unhappy past behind.I am so lucky to spend the happy time with my father in his last years.Now my heart is filled with love.A smile always graces my lips.

Many people think it is safe to use a cell phone while they are driving. Yet Scores of studies suggest that real multitaskers - those who can carry out multiple tasks equally well, make up just 2 per cent of the population. More surprisingly, the so-called "supertaskers" actually have differently structured brains to the other 98 percent. The brain areas that make supertaskers differ from the rest of the population are the same parts that are most different between humans and nonhuman primates , according to David Strayer, director of the applied cognition lab at the University of Utah. Scientists are unsure of the reason why some brains are different. In fact, we could all benefit from doing just one task at once. In most of us, scientists have located a "bottleneck in the brain" that may explain why we find it hard to do two things at once. The problem appears to be caused by a logjam of nerve messages. Faced with two almost simultaneous tasks less than 300 milliseconds apart, the brain's ability to deal with the second one slows down. The neural response to the second task was postponed until the response to the first was completed. This means that with e-mails, phone calls, text messages and online social media all competing for our attention, often against a background of television, radio or music, our brains can reach information overload. Scientists made the discovery after scanning the brains of volunteers attempting to multitask on a computer. The task was deliberately designed to involve the use of different senses and _ responses. Dr Rene Marois, one of the neuroscientists who carried out the experiment at Vanderbilt University in Nashville, Tennessee, said: "Our research offers neurological evidence that the brain cannot effectively do two things at once." The next step, the neuroscientists say, is finding out "why these areas cannot process two tasks at once." How many people can drive equally well while using a cell phone?

There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes. We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight. Another myth about eyes is that they can be replaced, or transferred from one person to another. They are close to one million nerve fibers that connect the eyeball to the brain, so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible. If a child wears appropriate glasses, _ .

A new system that scans customers' fingerprints and subtracts the grocery bill from their bank accounts has taken supermarkets in Germany to use the new system. "Almost a quarter of our customers pay with their fingers," said an employee at the headquarters. Edeka has tried the system at 70 of its supermarkets. It says it will introduce it at 200 others because customers like it. "At first we thought that only the young who really keep up with the latest technology would be interested, but we were wrong," said Stefan Sewoester from IT Werke. "Almost two-thirds of the people who use the system are 40 and older," he said. IT Werke, a computer company, is one of the pioneers of fingerprint payment software in Germany. It has helped about 150 shops, canteens and bars to put in the fingerprint scanning machines. Each costs about 2,000 euros. To sign up for the service, customers must have their fingerprints taken and leave their addresses and banking details with the shop. The shop then takes the cost of goods directly out of the customer's bank account. "It is especially a good thing for elderly people. Now they do not have to remember their pin to pay with their bank cards, or to scratch around for their glasses or cash." Sewoester said. The stores benefit from the system too. It saves more than time in the check-out line. It also cuts out the hidden costs of accepting electronic card payments. Why do elderly people benefit much from the fingerprint machine?

There was once a lonely girl who longed so much for love. One day while she was walking in the woods she found two starving songbirds. She took them home and put them in a small cage, caring them with love. Luckily, the birds grew strong little by little. Every morning they greeted her with a wonderful song. The girl felt great love for the birds. One day the girl left the door to the cage open accidentally. The larger and stronger of the two birds flew from the cage. The girl was so frightened that he would fly away. So as he flew close, she grasped him wildly. Her heart felt glad at her success in capturing him. Suddenly, she felt the bird go weak, so she opened her hand and stared in horror at the dead bird. It was her desperate love that had killed him. She noticed the other bird moving back and forth on the edge of the cage. She could feel his strong desire--needing to fly into the clear, blue sky. Unwillingly, she lifted him from the cage and threw him softly into the air. The lucky bird circled once, twice, three times. The girl watched delightedly at the bird. Her heart was no longer concerned with her loss. What she wanted to see was that the bird could fly happily. Suddenly the bird flew closer and landed softly on her shoulder. It sang the sweetest tune that she had ever heard. Remember, the fastest way to lose love is to hold on it too tight; the best way to keep love is to give it wings!

Laughter healing benefits and healing with laughter have become synonymous with Norman Cousins, the man who laughed himself to wellness. Norman Cousins was the editor of SaturdayReviewfor over 30 years. His story began in 1964, when doctors found that the connective tissue in his spine was becoming worse, which is a condition known as Ankylosing Spondylitis . The doctors, one of whom was a close friend of Cousins, said that his chance of survival was approximately 1 in 500. He read about the theory that negative emotions do harm to the body, so he thought that if negative emotions were damaging to health, then positive emotions should improve health. Faced with the real possibility of his approaching death, Cousins thought long and hard and eventually did three things completely contrary to medical opinion. First he began his own research on all of the various drugs he was on. He discovered that his condition was removing Vitamin C from his body and, based on Cousins' personal research, doctors agreed to take him off several of the drugs he was on and inject him with large doses of this supplement , as Cousins felt this may be his last hope. Secondly, Cousins made a decision to check out of the hospital and into a hotel room. The third thing Cousins did was get a movie projector and a large supply of funny films. On his first night in the hotel Cousins found that he laughed so hard at the films that he was able to stimulate chemicals in his body that allowed him several hours of pain-free sleep. When the pain returned he would simply turn the projector back on and the laughter would help sleep, and he was able to measure the changes in his body by measuring his blood sedimentation rate , and found that this rate dropped by at least 5 points each time he watched one of these videos. The treatment proved to be so effective that in very little time Cousins was off all painkillers and sleeping pills. He found that the laughter relieved the pain and helped him sleep. He returned to work and wrote about his experimental treatment in his book Anatomy of an Illness. In 1989, it was finally acknowledged in the Journal of the American Medical Association that laughter therapy could help improve the quality of life for patients with chronic illness and that laughter has an immediate symptom-relieving effect. According to Norman Cousins' own research, _ may be good for his recovery.

A quarrel at home may result in your falling ill. Don't laugh, it's true. Family matters including living habits and even the way we speak have a big effect on our health, doctors say. Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted in class when she heard her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a _ . It is because she is suffering from depression , caused by bad relations at home, doctors explained. "We don't get sick or stay well by ourselves," says Dr Robert Ferrer from the US. Ferrer shows that family forces may explain up to a quarter of health problems, in his recent research. The genes you get from your family may cause illness. If one of your parents has a heart attack, your risk of being affected may double. But effects on health are not only written in our DNA. Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment affect our health, too. Ferrer's research also found that if teenagers feel they are ignored or unimportant at home they are more likely to get sick. We may never fully understand all the effects that families have on our health. But just as individual problems can have effects on others, a small improvement can have big benefits, Ferrer said.

It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed",admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well". Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400,000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers, he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

I attended a birthday party in 1991. My teacher was then 59 years old. But her fellow teacher said that we were celebrating her 39thbirthday! We were all surprised and puzzled. After the party I was told by the fellow teacher that American women have a special saying about birthdays. If a woman is over 40, or even if she is 80, her birthday is always the 39th. If she is in her thirties, her birthday will be the 29th. And in her twenties, it's the 19th. They usually have their "real" birthday when they are below 20. This shows that American women, especially elderly women, are very sensitive about their ages. But my teacher always says, "We want to be younger," so about the age of Western women, my advice is that if you don't know it, don't ask about it; if you really know it, don't mention it.

More than 30,000 people went to the White House on Monday for the 136th Easter Egg Roll . President Barack Obama and First Lady Michelle Obama held the event by inviting thousands of kids to color and look for eggs. The theme of the day was "Hop Into Healthy, Swing Into Shape." It was part of the First Lady's "Let's Move!" program to reduce obesity rates among American kids. Mrs. Obama spoke to young reporters about her goal to get children to eat right and keep moving. "We are working to make sure that kids born today grow up healthy, learn how to have balanced meals, and get more physical activity into their lives," she said. Mrs. Obama said she wants children across the nation to understand that "exercise isn't just hard work, it's play. If you're running around with your dog, you're getting exercise. If you walk up the stairs, that's exercise, But if you're sitting in front of the TV or on a computer game, you're not exercising." The First Lady said that for kids who have balanced meals most of the time, having a special snack, like chocolate, will not hurt." And if you are active, you can splurge a little more," she said. Mrs. Obama's favorite "splurge food" is French fries. But she balances her splurging by exercising almost every day. She loves to play tennis and she practices yoga. "A lot of kids look up to athletes, and I think it's important for athletes to share their good habits," Mrs. Obama said. "Kids aren't just going to wake up and be LeBron James. He's practicing and eating right and working out and training. Our athletes can be really good messengers to kids who look up to them--they can say to kids, 'If you really want to be like me, then you really do need to eat your vegetables.'"

On behalf of the Electric Reliability Council of Texas (ERCOT), I would like to take this opportunity to thank you for conserving electricity during this period of continuous hot, dry weather in Texas. At ERCOT, we have been working around the clock to keep the electricity flowing, making sure you have the resources you need to stay productive and well this summer. While we are always charged with making sure you have adequate electricity, this summer has caused a particularly serious challenge to the electric grid . Because the heat has been sustained over the entire state with little or no rain or cloud cover, the strain on the electric grid has been greater than ever before. In Dallas and Austin, we are beating all-time records for triple-digit heat. We have hit three all-time demand peaks in the last two weeks alone, meaning we've used more electricity on three days this summer than on any other day in the history of ERCOT, which covers most of Texas. Additionally, Texas is experiencing economic and population growth while much of the rest of the country is not. All of these factors are contributing to very high energy usage this summer. As you probably read in your newspaper or saw on the news, ERCOT has issued appeals for conservation across the state this August. We have encouraged businesses and residential customers to help us save electricity between the critical hours of 3 and 7 p.m. For instance, turning off unnecessary lights, appliances and electronic equipment can help conditions significantly. Conservation efforts help us avoid statewide rotating outages and keep your lights on and air-conditioners running. Conservation not only keeps power and cool air flowing to every citizen, it ensures that uninterrupted power flows to critical care customers, who are easily harmed in the extreme heat. While ERCOT has not called for rotating outages this summer, it is important to remember that we only carry out these orderly, temporary outages to prevent a catastrophic collapse of the electric grid. As you may remember from the Northeast blackout a few years ago, once a grid failure occurs, it can take days to restore power to all consumers. Your conservation efforts help us prevent this from happening. While ERCOT always carries reserves, our power supply is not unlimited. With your help and conservation efforts, though, we can keep residents and businesses healthy and productive this summer. Serious challenge to the electric grid is due to the following facts Except _ .
