Why doesn't the unemployment rate ever reach zero? Economists, who generally believe that supply tends to meet demand, have long thought about this question. Even in good times, i.e. not now, there are people who can't find work. And even in bad times, i.e. now, there are job openings. With over 14 million people out of work and looking for a job, you would think every available job would be filled. But that's not the case. Not now and not ever. On Monday, the Nobel Prize committee awarded the prize for economics to the three scholars who have done the most to explain this phenomenon. Two of the winners are Americans, Peter Diamond of MIT and Dale Mortensen of Northwestern. The third winner is Christopher Pissarides, who teaches at the London School of Economics and was born on Cyprus. Like most of economics, what they have found about why the jobless and ready-employers don't find each other seems obvious. You have to find out there is job opening you are interested in. Employers need to get resumes . It takes a while for both employers and employees to make the decision that this is what they want. And these guys came up with a frame-work to study the problem of why people stay unemployed longer than they should and what can be done about it. So what would today's Nobel Prize winners do to solve the current problem of the unemployed? And does the awarding of the prize contribute to the politicians' lowering joblessness? Speaking from his north London home, Pissarides told The Associated Press the announcement came as "a complete surprise" though his work had already helped shape thinking on both sides of the Atlantic. For example, the New Deal for Young People, a British government policy aimed at getting 18-24-year-olds back on the job market after long periods of unemployment, "is very much based on our work," he said. "One of the key things we found is that it is important to make sure that people do not stay unemployed too long so they don't lose their feel for the labor force," Pissarides told reporters in London. "The ways of dealing with this need not be expensive training - it could be as simple as providing work experience." What is it that leads to their winning the prize?

Today anyone will accept money in exchange for goods and services. People use money to buy food, furniture, books, bicycles and hundreds of other things we need or want. When they work, they usually get paid in money. Lots of the money today is made of paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money. In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Some Africans once used elephant tusks, monkey tails, and salt as money. The first metal coins were made in China. They were round and had a square hole in the center. Different countries have used different metals and designs for their money. Later, countries began to make coins of gold and silver. But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than the paper money used today. Money has had an interesting history, from the days of shell money until today. The first metal coins looked like _ .

Getting in touch with nature can help keep people fit, reducing the burden of sickness on the health service, conservation experts say. Natural England is starting a campaign to get people to spend more time outside among the country's wildlife and natural environment. The aim of the campaign is to get people to have more contact with nature by promoting green spaces and encouraging health professionals to incorporate (......) the thought into the advice and care plans that they give to patients. Being close to nature can cut stress and increase physical activity. Dr. William Bird from Natural England said: "Increasing evidence suggests that both physical and mental health are improved through contact with nature. Yet people are having less contact with nature than at any time in the past. This has to change. Children with attention disorders have been shown to improve when they have contact with nature. People recovering from operations have been shown to need fewer painkillers if they look out at green fields." He also said people were more likely to keep up with their regular exercise in natural settings, rather than in a gym or leisure centre. Natural England is working with the BBC and more than 300 partners to promote its campaign, which will be the first of four campaigns to get people more involved in nature. Liz Cleaver, from the BBC, said: "These campaigns now provide the public with the opportunity to get outside and to get actively involved in nature close to where they live. That's great for wildlife --but it's also fantastic for everyone's health and well-being." The campaign has also received support from the government. Dr. Fiona Adshead, England's deputy chief medical officer, said: "I welcome Natural England's commitment to encourage and enable people to make use of the country's outdoor space for physical activity." The purpose of the campaign is to _ .

The Ministry of Health has called for more awareness from the public on the mental health of the young,as part of efforts to mark World Mental Health Day. More than 15 percent of the Chinese youth have been found with mental problems,and about 30 million young people under 17 are suffering from depression,the Shanghai-based Wenhui Daily reported. The World Health Organization estimated that before 2020,the rate of children with mental problems will increase to 50 percent,and mental problems will become a major factor behind death and illness in the young worldwide. Deng Xiaohong,the spokesperson for the Beijing Municipal Health Bureau,said rapid social change is one of the reasons behind the rising number of youngsters with psychological problems. If these mental diseases are not _ on time,occurrence of crime,drugtaking and other dangerous behavior are expected to rise. Experts said mental disease could be caused by many factors,such as the inability to handle interpersonal relations well,unstable emotions and pressure from the overload of study. A number of experts have also said the one-child policy is another reason leading to poor mental health in the young. Children were said to be too "spoiled" and "selfish" in one-child families. Schools in many cities were reported to roll out measures to help students maintain their mental well-being. Yin Jingmiao,a teacher of the Beijing No. 105 Middle School,told China Daily that the school invites psychologists to provide counseling to students three times a month. "Students can be arranged to have 40-minute counseling sessions," Yin said. The school also gives lectures on mental health to senior grade students before they take the national college entrance exams,to help ease any anxiety arising from the tests. Which of the following statements is true according to the passage?

"By 2020,about 50 percent of the students in China will have mental problems.",
"Mental problems mainly appear among the youth while they are seldom seen among adults.",

What would life be like without rich, creamy, mouthwatering, melt-in-your-mouth chocolate? Life would be bitter for most Americans. They spend about $13 billion a year buying all sorts of chocolate treats. However, for the African children who toil under slavelike conditions on cacao plantations, life is not sweet. The cacao bean is the main ingredient in the chocolate. According to a 2002 survey by the International Institute of Tropical Agriculture and the US Agency for International Development, about 284,000 children work in dangerous conditions on cacao farms in western Africa. More than half those children are younger than 14. Many were sold into forced labor to work 12 hours or more a day on the cacao plantations. A number of international organizations, including several African governments, recently began a program to eliminate child labor on cacao plantations. Under the program, government officials will remove children from abusive working situations while teaching farmers about child labor issues. The program will also make borrowing money easier for cacao farmers. Officials hope farmers will use the money to invest in their farms and hire paid laborers.

Very soon a computer will be able to teach you English. It will also be able to translate any language for you,too. It's just one more incredible result of the development of microprocessors - those tiny parts of a computer commonly known as "silicon chips". So give up going to classes, stop buying more textbooks and relax. In a couple of years you won't need the international language of English. Already Texas Instruments in the United States is developing an electronic translation machine. Imagine a Spanish secretary, for example, who wants to type a letter from the boss to a businessman in Sweden. All he or she will have to do is this: first type the letter in Spanish. The letter will appear on a television screen. After a few seconds the translated letter will appear on another television screen in Stockholm in perfect Swedish. And that's not all. Soon a computer will be able to teach you English, if you really want to learn the language. You'll sit in front of a television screen and practice endless structures. The computer will tell you when you are correct and when you are wrong. It will even talk to you because the silicon chips can change electrical impulses into sounds. And clever programmers can predict the responses you, the learner, are likely to make. So think of it.You will be able to teach yourself at your own pace.You will waste very little time,and you can work at home.And if after all that,you still can't speak English,you can always use the translating machine.In a few years,therefore,perhaps there will be no need for BBC Modern English,or BBC English by Radio programmes - no more textbooks or teachers of English.Instead of buying an exciting new textbook,the computer will ask you to replace it with a microprocessor.Fast,reliable and efficient language learning and translating facilities will be available to you.Think of that,no more tears or embarrassing moments.One little problem is that a computer can't laugh yet - but the scientists are working on it.Happy learning!

Do you have the experience of taking music lessons against your wishes? Perhaps you have complained about it because you thought it took you much playtime. But now you'd better thank your parents for their time and money spent on your musical training. A recent study suggests music lessons can make children have better memories than their peers . The Canadian study showed that after one year of musical training, children did better on a memory test than those who didn't take music lessons. The researchers made the children aged between 4 and 6 into two groups -- one group of children took music lessons outside school, and the other didn't take any musical training. In one year, they took four tests in different times. The results showed brain development changes at least every four months. The children taking music lessons not only did better in musical listening but also made faster progress in other ways, such as reading, writing, math and IQ. People say music is the good medicine for a broken heart. Now it seems music can also help us to improve our memories. We are sure to find more and more in the wonderful world of music. The Canadian study showed that brain development changes _ .

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

[
"The age people become adults depends on whether they can vote or not.",
"The age people become adults depends on their own independence and responsibility.",
"The age people become adults depends on if they are eighteen years old.",
"The age people become adults depends on when they get the key to their houses."

As motorways become more and more blocked up with traffic, a new generation on flying cars will be needed to ferry people along skyways. That is the conclusion of engineers from the US space agency and aeronautical firms, who _ future commuters traveling by "skycar". These could look much like the concept skycar shown in the picture, designed by Boeing research and development. However, such vehicles could be some 25 years from appearing on the market. Efforts to build flying vehicles in the past have not been very successful. Such vehicles would not only be expensive and require the skills of a trained pilot to fly, but there are significant engineering challenges involved in developing them. "When you try to combine them you get the worst of both worlds: a very heavy, slow, expensive vehicle that's hard to use," said Mark Moore, head of the personal air vehicle(PAV) division of the vehicle systems program at Nasa's Langley Research Center in Hampton, US. But Boeing is also considering how to police the airways and prevent total pandemonium -if thousands of flying cars enter the skies. "The neat, gee-whiz part is thinking about what the vehicle itself would look like," said Dick Paul, a vice president with Phantom Works, Boeing's research and development arm. "But we're trying to think through all the consequences of what it would take to deploy a fleet of these." Past proposals to solve this problem have included artificial intelligence systems to prevent collisions between air traffic. Nasa is working on flying vehicles with the initial goal of transforming small plane travel. Small planes are generally costly, loud, and require months of training and lots of money to operate, making flying to work impractical for most people. But within five years, Nasa researchers hope to develop technology for a small plane that can fly out of regional airports, costs less than $100,000(PS55,725), is as quiet as a motorcycle and as simple to operate as a car. Although it would not have any road-driving capabilities, it would bring this form of travel within the grasp of a wider section of people. The new technology would automate many of the pilot's functions. This Small Aircraft Transportation System(Sats) would divert pressure away from the "hub-and-spoke " model of air travel. Hub-and-spoke refers to the typically US model of passengers being processed through large "hub" airports and then on to secondary flights to "spoke" airports near their final destinations. Now Nasa researchers' aim is to _ .

NEW YORK (Reuters Health)--Kids who eat better perform better in school, a new study of Nova Scotia fifthgraders confirms. Students who ate an adequate amount of fruit,vegetables,protein,fiber and other components of a healthy diet were significantly less likely to fail a _ test,Dr.Paul J.Veugelers of the University of Alberta in Edmonton and colleagues found. While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic, Veugelers and his colleagues note.To investigate,they looked at 4, 589 fifthgraders participating in the Children's Lifestyle and Schoolperformance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment. The better a student's eating habits based on several measures of diet quality,including adequacy and variety, the less likely he or she was to have failed the test, the researchers found,even after they adjusted the data for the effects of parental income and education, school and sex.Eating plenty of fruit and vegetables, and getting fewer calories from fat, was also associated with a lower risk of failing the test. To date, Veugelers and his team say, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition . "This study extends current knowledge in this area by demonstrating the independent importance of overall diet quality to academic performance.We should not only realize the importance of children's nutrition at breakfast but also that throughout the day," the researchers conclude. Another research from the UK is suggesting that children's diets in the preschool years affects how they perform at school later on.The researchers from the Institute of Education, at the University of London say in fact that what children were eating in those days before primary school has more of an effect than the chicken nuggets they ate at lunchtime.The researchers say they have found that children who ate a diet of "junk food" at the age of three, made less progress in school between the ages of six and ten.They say children's diet at later ages appears to have less impact on their school attainment. .According to Dr.Paul J.Veugelers, students who have a healthy diet _ .

Nearly 600,000 Americans lost their jobs this past month, pushing the nation's unemployment rate to 7.6 percent. But not all of those fired workers are sitting at home, reading the job advertisements and waiting for the phone to ring. Thousands of people are returning to school, making public colleges and universities among the few bright places in the disappointing US economy. At a time when many Americans have had their work hours cut or have even lost their jobs, Sherian Huddleston is working overtime. She works at Middle Tennessee State University (MTSU) where she oversees the enrollment of new students. The university's population grew by 800 students this term --an increase of 4 percent over last spring's enrollment. Huddleston says seeing the enrollment rise in a failing economy is not unexpected. "When people are out of work," she points out, "they will ask 'What else can I do?' or 'What other careers can I follow?' They will often return to school if they have not completed a degree before." Older returning students aren't the only ones increasing the enrollment at MTSU. Huddleston says she's also seeing an increase in student transfers . "Students who went out of state, or even within the state, to more expensive schools are transferring to public schools to make use of the lower cost of going to school here," she explains. Which is the best title for the passage?

It is not a good idea to stop the actor Richard Griffiths in the middle of a play.During the past year he has stopped performances many times at the National Theatre when mobile phones rang, and he threw out one member of the audience because she failed to turn off her phone. So when a mobile rang out for the third time during his performance in Alan Bennett's The History Boys, he spoke angrily to the theatergoer , "I am not going to compete with these electronic devices ." Griffiths' actions led to a debate in the UK theatre world over whether phones should be forbidden by law from British theatres, too.Actors have already asked the government to legalise the use of an electronic device that stops mobile phone signals in theatres. Technology companies have "stopping" devices that send out a high-powered signal on the same frequency as a mobile phone, stopping the mobile phone signal. However, these are forbidden in many countries because they might stop emergency calls from being made. Rosemary Squire, president of the Society of West End Theatre, said, "Phones are one of the biggest problems theatres face.We should look at equipment that could stop phones or make a London-wide theatre rule." Nick Allott, the managing director of Sir Cameron Mackintosh's theatre group, said, "We would all welcome some ways of stopping ringing phones but doctors and emergency workers need to be connected in a theatre and we mustn't stop that." What can we do to solve the problem? According to the passage, "stopping" devices _ .

"If music is the medicine of the soul , let it play on," said a famous person. I think he said so because probably he got some help from music. Music has some strange abilities. Medical scientists have found that a person that feels stressed can actually listen to some kind of music and become well. The researchers said that since stress comes as a result of life events such as starting a new family, starting a new business, and starting a new job, one can actually listen to good music and feel good because good music touches the human mind in a positive way. Music helps you to forget the life events that make you worried and remember the important events that once happened in your life. Depression is a disease cause by stress, smoking, social problems and so on. Depression is also caused by problems such as failure in business. Depression may bring us weakness, headache, and loss of concentration. Good music makes one remember happy moments or good days. If you play music about love, it makes you feel like falling in love again though you may have had several upset experiences. And such good feeling make you healthy. Anxiety is another health problem that can be controlled by music. Anxiety is a side effect of some major health problems such as cancer of the liver and cancer of the breast. Good music makes you feel relaxed and removes the pains from these diseases and you feel all right. Good music can send you to sleep. And you need to know that sleep puts your body in a healthy condition. Sleep takes away the effects of stress, depression and anxiety from a person.

Do you like dogs? Do you know the following things about dogs? The first pet dog Dogs are meat-eating animals. They belonged to the family of wolves a long time ago. About 15,000 years ago, people started keeping wolves for hunting . Over the time, the wolves began to look like dogs and they became people's pets. What a dog looks like Dogs come in different sizes, colors and shapes, but they're the same in some ways. All kinds of dogs have a set of forty-two strong teeth for eating. They have sharp claws at the end of their feet for digging up soil and holding onto the ground when they walk. They have very good eyesight. They also have high ability to hear and smell. How a dog grows A mother dog gives birth to one to twelve babies at a time. New-born baby dogs cannot see or hear until they are two weeks old. The mother dog gives the baby dogs milk. When they are four weeks old, they start eating soft food. When they're eight weeks, the baby dogs have very strong legs and they can go for long walks. How to read a dog's feelings Dogs act differently when they have different feelings. When a dog is angry, it opens its mouth and shows its teeth. When a dog is frightened, it lowers its ears and holds its tail between its legs. A happy dog always wags its tail. ,. (10) People have started keeping dogs as pets since _ .

It was late in the afternoon, and I was putting the final touch on a piece of writing that I was feeling pretty good about. I wanted to save it, but my cursor had frozen. I tried to shut the computer down, and it seized up altogether. Unsure of what else to do, I yanked the battery out. Unfortunately, Windows had been in the midst of a crucial undertaking. The next morning, when I turned my computer back on, it informed me that a file had been corrupted and Windows would not load. Then, it offered to repair itself by using the Windows Setup CD. I opened the special drawer where I keep CDs. But no Windows CD in there. I was forced to call the computer company's Global Support Centre. My call was answered by a woman in some unnamed, far-off land. I find it annoying to make small talk with someone when I don't know what continent they're standing on. Suppose I were to comment on the beautiful weather we've been having when there was a monsoon at the other end of the phone? So I got right to the point. "My computer is telling me a file is corrupted and it wants to fix itself, but I don't have the Windows Setup CD." "So you're having a problem with your Windows Setup CD." She has apparently been dozing and, having come to just as the sentence ended, was attempting to cover for her inattention. It quickly became clear that the woman was not a computer technician. Her job was to serve as a gatekeeper. Her only duty, as far as I could tell, was to raise global stress levels. To make me disappear, the woman gave me the phone number for Windows' creator, Microsoft. This is like giving someone the phone number for, I don't know, North America. Besides, the CD worked; I just didn't have it. No matter how many times I repeated my story, we came back to the same place. She was calm and polite. When my voice hit a certain decibel , I was passed along, like a hot, irritable potato, to a technician. "You don't have the Windows Setup CD, ma'am, because you don't need it," he explained cheerfully. "Windows came preinstalled on your computer!" "But I do need it." "Yes, but you don't have it." We went on like this for a while. Finally, he offered to walk me through the use of a different CD, one that would erase my entire system. "Of course, you'd lose all your e-mail, your documents, your photos." It was like offering to drop a safe on my head to cure my headache. "You might be able to recover them, but it would be expensive." He sounded delighted. "And it's not covered by the warranty !" The safe began to seem like a good idea, provided it was full. I hung up the phone and drove my computer to a small, friendly repair place I'd heard about. A smart, helpful man dug out a Windows CD and told me it wouldn't be a problem. An hour later, he called to let me know it was ready. I thanked him, and we chatted about the weather, which was the same outside my window as it was outside his. It can be inferred from the passage that the differences between the Global Support Centre and the local repair shop lie in all the followings except _ .

55% of deaths caused by road accidents occur in the first few minutes after a crash. Up to 85% of these deaths could be prevented if first aid were given. The first person on the scene of a road accident will almost certainly be another road user. So as a driver your knowledge of first aid could make a real difference to someone in the event of a road accident. Assess conditions *Remain calm. Judge the scene and seriousness of the collision. *Determine what has happened, how many people and vehicles are involved and the exact location. *Determine how many casualties there are, what is the severity of the injuries, whether anyone is trapped, and whether there is a danger of fire. Make safe *Make sure you stay safe and keep off the road. If you need to stop or warn approaching cars, signal to them from the pavement. Wear reflective clothing, use warning triangles, flashing lights and warning lights. Don't smoke. *If you are in a car and you come across an accident, first park safely and turn off the engine before you get out to help. Use a triangle warning danger if necessary. *Consider the safety of others. Don't move the vehicles, look out for dangers -- leaking fuel, chemicals, broken glass or dropping loads -- guide uninjured passengers to a place of safety. Call for help Dial 999 (or 112) for the emergency services. If there is no phone nearby, send two people in opposite directions to seek help. Do this as soon as you can or get someone else to do it while you deal with an injured person. You will need to tell the emergency services: *where you are *what has happened (describe the accident) *how many people are injured *whether they are breathing or bleeding. The operator will talk you through what to do while you wait for an ambulance to arrive. Apply emergency first aid *Remain calm. Reassure the victims. *Do not allow smoking or offer food or drink to casualties as this could _ urgent medical treatment. When a driver is applying first aid, which of the following is proper?

[
"Stand in the middle of the road to stop or warn approaching cars.",

For thousands of years, man has enjoyed the taste of apples. Apples, which are about 85 percent water, grow almost everywhere in the world but the hottest and coldest areas.Among the leading countries in apple production are China, France and the United States. There are various kinds of apples but a very few make up the majority of those grown for sale.The three most common kinds grown in the United States are Delicious, golden Delicious and McIntosh. Apples are different in color1, size and taste.The color1 of the skin may be red, green or yellow.They have various sizes with Delicious apples being among the largest.The taste may be sweet or tart .Generally sweet apples are eaten fresh while tart apples are used to make applesauce.Apples can also be found in many foods (especially desserts) and drinks. Many beneficial health effects have been found from eating apples. However, the seeds are slightly poisonous. Apple trees may grow as tall as twelve meters.They do best in areas that have very cold winters.Although no fruit is _ during the winter this cold period is good for the tree. At least 55 million tons of apples were grown worldwide in 2010, with a value of about $ 10 billion. China produced about 35% of this total. The United States was the second-leading producer, with more than 7.5% of world production. Iran was third, followed by Turkey, Russia, Italy and India. It can be learned from the text that Delicious apples are _ .

Last weekend, our family went to have Christmas dinner in a restaurant. We were the only family with a baby in the restaurant. Suddenly, my baby Erik became excited when we were enjoying our meal. I looked around and saw an old man with old clothes and dirty old shoes. His hair was unwashed. He was smiling at my Erik. "He might hurt my Erik," I thought. Everyone in the restaurant looked at us and the old man. Then we decided to leave. The old man sat between the door and us. As I walked closer to the man, I turned my back. Suddenly, Erik leaned over my arms, reaching with both arms in a baby's pick-me-up position . Before I could stop him, Erik had escaped from my arms to the man's. Soon the very old smelly man and my young baby developed a kind of friendship. Erik put his little hand on the man's face, and I saw the old man closed his eyes and tears running down his face. His aged hands held my baby so gently . A moment later, the old man opened his eyes, passed me my baby and said, "Thank you, Madam. You've given me the best Christmas gift." I cried, with my face burning hot. A child saw a soul , but a mother saw only a kind of clothes. At first, the writer thought the old man was _ .

Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plan. So airlines offer passengers food. But it is common that they feel bad about food taste. Do you agree? To solve this problem, airlines try hard to improve their food. They would like to do so because they don't want to lose customers. However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure reduces one third of the sensibility of our taste buds . So our taste buds become senseless. The sad face, however, is that our noses don't know it. All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy food. Without doing so, the food would be tasteless. Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste. Though scientists try their best, it is not as easy as they thought. Because they can't deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them. Why do scientists feel it hard to made food on the plane taste good?

I learned a long time ago that hair has meanings--plenty of meanings. Growing up in the 1960s, my friends and I struggled without parents' control over the length and style of our hair. At the time, hair represented our need to break free from adults in our lives. Long hair represented our freed inner selves. My clients are often surprised when I asked them questions about their hairstyle--why they choose it, how else they've worn their hair, how they feel about it, and so on. However, while it may seem to be a simple topic, even today our hairstyles still have many psychological and emotional meanings. Understanding some of those meanings can lead to understanding of many different aspects of a person's mind. How we view our hair, for example, can show something about how we view ourselves. Our hair can show physical and emotional wellbeing, desirability, and even social and financial status. When it becomes dull or fragile, it can communicate emotional and physical diseases. But hair can also show unrecognized and often unspoken daydreams about oneself and one's world. One woman--a successful professional--wore her long hair in a thick bun . But one day she showed me that tangled hair was kept in the bun. She said that she never brushed out the tangles because the hair showed her secret image of herself as a helpless, disturbed woman, like Ophelia in the play Hamlet. Another woman came to therapy in a huge shirt and huge pants that she believed they could hide the weight she had put on since the birth of her child. She talked about how much she hated her body and how helpless she felt about doing anything about it. But her hair was always beautifully coloured and decorated. When I pointed out that she seemed to have a different relationship with her hair from she did with her body, she said that her hair had been thinning and that she was trying to make it look as good as she could. I pointed out that what she was doing with her hair and her body was kind of contradictory, and wondered if she had any thoughts about that. She was surprised. But as we talked about her contradictory attitudes towards different parts of her physical self, we began to open up all sorts of other thoughts and ideas about her inner self. And interestingly, as we continued opening those internal doors, changes started to happen. She started eating differently and exercising regularly. One day some months later, she appeared in my office in skinny jeans and a tight sweater, and her hair was pulled back in a ponytail. "I decided to see what would happen if I stopped trying to hide myself, " she said with a big smile. "And...? " I asked. "People keep smiling at me in the street. My husband hugged me this morning for the first time in ages. And I feel good! " Besides, selfrespect in both men and women can be damaged by thinning hair;they may feel alone even though they are really not. Given our cultural focus on physical appearance, youth, and health, hair loss can be unpleasant for both men and women. The market is filled with hairenhancing treatments, but there are those who have decided to be against the system and change to the "bald is beautiful" position. But it is much harder for women to take the "bald is beautiful" approach to hair loss. We tend to try to hide it in one way or another. But no matter what approach you use, it is important to remember that the thickness of your hair has nothing to do with your value in the world. Remember that you have nothing to be ashamed of if you have thinning hair. Thinning hair may not be something you can change, but it doesn't have to control how you represent the person who lives underneath it. In the 1960s, long hair represented _ .

Hummingbirds have got their name from the distinct "hum" sound made by their rapidlyflapping wings. The size of the bird decides the number of flaps it can do. The average lifetime of a hummingbird is 3 or 4 years, but some of them have lived beyond 12 years also. They are unique in many ways. Besides the number of rapid flaps they can do per second, they can also fly backwards. Hummingbirds have an amazing sense of assessing the amount of sugar in thenectar they eat. They feed on the nectar of flowers. Hummingbirds do not feed on flowers whose nectar contains less than 10% sugar. Talk about a sweet tooth! As they cannot sustain themselves on nectar alone because of its poor nutritional value, they also feed on insects and spiders, and hummingbird food mixture that one can make at home. Attracting hummingbirds to your garden will require a little planning. Plant butterfly bush, mimosa, coral bells, foxglove, morning glory, etc. These flowers attract the hummingbirds due to their highvisibility and nectar production. Avoid usingpesticides , as it will not only kill the insects around the flowers, but hurt the hummingbirds as well. A common food for these birds is the sweettastingsugar syrup . Hummingbird food ingredients are just two: sugar and water. Take a large clean bowl, pour in it four cups of hot water, and dissolve one cup of table sugar in it. Stir slowly until all sugar has dissolved. Hummingbirds, tiny as they are, collect a lot of nutrition. Providing them with hummingbird food mixture made of sugar water is a sure way to get all these beauties humming in your garden. Hummingbirds will have some little animals for their meal when _ .

Tens of thousands of smartphone applications are running ads from the overwhelming advertising networks that change smartphone settings and copy people's contact information without permission. Aggressive ad networks can disguise ads as text message notifications , and sometimes change browser settings and bookmarks. Often, the ads will upload your contacts list to the ad network's servers--- information that the ad network can then sell to marketers. Sounds scary? It's not a giant problem yet, but it's a growing one. As many as 5% of free mobile apps use an "aggressive" ad network to make money, according to Lookout, a San Francisco-based mobile security company. PhoneLiving was one of the most popular app developers to use these kinds of ad networks; their dozens of talking animal apps have been downloaded several million times. Later, PhoneLiving says it has mended its ways. The company admittedusing _ techniques to make money from its apps, but said it dropped those methods at the start of July because of bad reviews and declining downloads. The most popular type of apps that use aggressive ad networks are "Personalisation" apps, which include wallpapers. Comic and entertainment apps are also among the most likely to have rogue ad networks running behind the scenes. Like aggressive pop-ups on PCs, the bad software isn't easy to get rid of. Though the damage can typically be removed by deleting the app, it can be hard to tell which app is causing the problems. When developers create free mobile apps, they usually make money through ads displayed within the app. App makers don't usually tell people which ad network they are using, which makes it hard to avoid the known offenders. The best defense is to read reviews and avoid downloading apps that have attracted many complaints. What is an example of bad behavior by the annoying mobile ads?

What is the color1 of the universe? Astronomers had not answered this question, until two months ago. That is when two American astronomers reported on their study of all the light in the universe. They said that the universe would appear to the human eye to be a light greenish color1, called turquoise . Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their finding in January. They presented the research at a meeting of the American Astronomical Society. They said that finding the color1 of the universe was not part of their serious scientific research. They did it for fun. However, earlier this month, the scientists admitted to making a mistake. They said their finding was much more color1ful than it should have been. They now say the light from our universe is closer to white. It is more like a milky or creamy white color1. Their study attempted to show what people might see if they could observe the universe from far away. The scientists found the average color1 by combining light from about two-hundred-thousand star systems. Their information came from an observatory in New South Wales, Australia. These scientists and color1 engineers attempted to reproduce the result. Mark Fairchild of the Rochester Institute of Technology in New York was the first person to identify a mistake. He discovered a mistake in the computer software program used by the Johns Hopkins scientists. When the mistake was corrected, the results changed. The new color1 of the universe is much less color1ful. It is very close to white. The scientists have apologized for the mistake. They are now working with the Rochester Institute of Technology to produce more images of the color1 of the universe. They also asked for suggestions for a name for the new color1 of the universe. We can infer from the passage that _ .

San Francisco(People's Daily Online)-- Apple Inc. Tuesday introduced its mobile payment service Apple Pay alongside the company's iPhone 6 Plus and Apple Watch at the Flint Center in Cupertino, California. What apple does is to replace consumers' wallet with its cell phone. Apple said it hopes to speed up the checkout process, make credit-card payments more secure and ultimately, to replace physical wallets. With the near-field communication technology, Apple's gadgets like iPhone and Apple watch can transmit a radio signal between the device and a receiver when the two are in an inch apart. "To pay, just hold your iPhone near the contactless reader with your finger on Touch ID. You don't even have to look at the screen to know your payment information was successfully sent," Apple says on its official website. Apple said that each transaction would be authorized with a one-time, unique number, creating a security code that it said is more secure than the one on the back of your credit card because cashiers won't see your name, card number or security code. The service will work with the three major payment networks -- American Express, MasterCard and Visa -- and Apple said that there are 220,000 merchant locations that accept these contactless payments. When some applaud this disrupted service that will compete with Paypal and endanger other online payment companies, some others concern about its safety, especially when another retailer Home Depot confirmed a data opening yesterday and iCloud was reported exposing nude pictures of celebrities a week ago. Leo Zheng, a technology reporter in Silicon Valley said: "When Apple attracts consumers to put all their cards into one iPhone and promised the security, Jennifer Lawrence should say something." Which can be the best title for the passage?

Northern Europeans spend a lot of time in their cold and cloudy winters planning their summer holidays. They are proud of their healthy color when they return home after the holiday. But they also know that a certain amount of sunshine is good for their bodies and general health. In ancient Greece people knew about the healing powers of the sun, but this knowledge was lost. At the end of the nineteenth century a Danish doctor, Niels Finsen, began to study the effect of sunlight on certain diseases, especially diseases of the skin. He was interested not only in natural sunlight but also in artificially produced rays. Sunlight began to play a more important part in curing sick people. A Swiss doctor, Auguste Rollier, made full use of the sun in his hospital at Lysine. Lysine is a small village high up in the Alps. The position is important: the rays of the sun with the greatest healing power are the infra-red and ultra-violet rays; but ultra-violet rays are too easily lost in fog and the polluted air near industrial towns. Dr. Roller found that sunlight, fresh air and good food cure a great many diseases. He was particularly successful in curing certain forms of tuberculosis with his "sun-cure". There were a large number of children in Dr. Roller's hospital. He decided to start a school where sick children could be cured and at the same time continue to learn. It was not long before his school was full. In winter, wearing only shorts, socks and boots, the children put on their skis after breakfast and left the hospital. They carried small desks and chairs as well as their school books. Their teacher led them over the snow until they reached a slope which faced the sun and was free from cold winds. There they set out their desks and chairs, and school began. Although they wore hardly any clothes, Roller's pupils were very seldom cold. That was because their bodies were full of energy which they got from the sun. But the doctor knew that sunshine can also be dangerous. If, for example, tuberculosis is attacking the lungs, unwise sunbathing may do great harm. Today there is not just one school in the sun. There are several in Switzerland, and since Switzerland is not the only country which has the right conditions, there are similar schools in other places. According to the passage, when did sunlight begin to play a more important part in the treatment of disease?

And the biggest of all is the International Space Station(ISS). From May to July is the best season to watch the ISS flying over the earth. And people can see it with their eyes. The ISS is the biggest satellite and scientists want to live on it. They think that the best way to learn more about space is to live there. When the space station is finished , it will be like a city in space. People will stay and study there with many of the things they have at home. Laboratories, living rooms and power stations are being built. The ISS is the most expensive space program. Billions of dollars are being spent on it every year. Scientists hope that the ISS will be _ for future space exploration . "The ISS will help us understand the human body better, explore space and study the earth. It can help us make life on the earth better, " said Kathryn Clark , an ISS scientist. Sixteen countries are part of the program: the US, Russia, Canada, Japan, Brazil and 11 European countries.

Lots of folks don't think about what they eat over the holiday season until January, when they stare sadly at the number on the scale and then hurry off to hit the gym, join Weight Watchers or pick up the latest diet book. It doesn't have to be that way. Health experts say you can still enjoy the holidays. "It's OK to indulge , but it doesn't mean you have to gain weight," said Karen Ansel, a New York-based registered dietitian and a spokeswoman for the American Dietetic Association (ADA). Jessica Crandall, a registered dietitian from Denver who's also an ADA spokeswoman, added that gaining weight during the holidays and then working hard to lose it again is not good for a person's body. For starters, people interested in maintaining their weight during the holidays should keep eating on a regular schedule, the two dietitians said. Research has shown that people who skip meals -- particularly breakfast -- end up eating more throughout the day. "Try and stick to consistent meal times so you can avoid being overly hungry," Crandall said. "When you're overly hungry, you can make some bad decisions regarding what you eat. Don't starve yourself during the day waiting for that party at night -- because you'll eat too much or overeat." Ansel suggests that you think now about the foods you really enjoy and plan to focus on those while eating less of more common fare. Be careful, too, about alcohol intake, for a couple of reasons. Alcoholic drinks, particularly the fancy ones handed out at holiday time, tend to come loaded with calories. "It's usually what you're adding to a drink that contains the calories," Crandall said. Also, if you're drunk, you might forget to watch what you're eating. "It totally lowers your inhibitions ," Ansel said. Other holiday eating tips, suggested by Crandall and Ansel, include: *Eat lots of vegetables, and eat them first before moving on to the other items on your plate. *Recognize that many holiday extras, like cheese or cranberry sauce, come loaded with calories. "If those aren't your favorite foods, don't put them on your plate," Crandall said. *If your favorite food has a lot of calories, be sure to minimize your portion. "Two bites cure the craving," Crandall said. "After that, you're just really feeding your old habits. *After a big holiday meal, don't sink into a chair or couch. Go for a walk outdoors or participate in some other activities that help burn off some of the calories you've just eaten. Both Karen Ansel and Jessica Crandall _ .

Human cloning technology could be used to reserve heart attacks. Scientists believe that they may be able to treat heart attack by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged, and other problems may be solved if human cloning and its technology are not forbidden. With cloning, _ couples could have children. Current treatments for infertility, in terms of percentages, are not very successful. Couples go through physical and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before. We should be able to clone the bone marrow for children and adults suffering from leukemia . This is expected to be one of the first benefits to come from cloning technology. We may learn how to switch cells on and off through cloning and thus be able to cure cancer. Cloning technology can be used to test for and perhaps cure gene-related diseases. The above is just a few examples of what human cloning technology can do for mankind. This new technology promises unprecedented advancement in medicine if people will release their fears and let the benefit begin. According to the text, one of the first expected benefits from cloning technology is in _ .

Four out of ten women who diet end up heavier than when they started watching their waistline, a study revealed today. The research also showed that a large percentage of women start noticing the pounds creeping back on just 21 days after reaching their ideal weight. Yesterday, Dr Ian Campbell of the Jenny Craig weight management program said, 'In the UK 61.4 percent of adults are overweight or obese. Successful weight management requires a long-term commitment in order to lose weight successfully and for good. Dieting can be a real challenge so setting realistic goals and remaining focused on them is important. Otherwise as this research shows, women could end up heavier than when they started.' The "Food, Body, Mind" report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss. Six in ten said they were currently on a diet and one in five women said they were on a continuous diet. It found the most common triggers to start dieting was seeing their reflection in the mirror, preparing for a summer holiday or unflattering photos posted on social networking sites. Other popular reasons include comments by friends or relatives or their other half. However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more. The average is ten days. Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal. Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers' polishing off their children's leftovers was another common cause of weight gain. Which of the following is NOT the reason why many people stop dieting very soon?

I think it's really very good to be a doctor. On the one hand, you can save people; on the other hand, they share their experiences of life with you. I've been a doctor in Los Angeles.

When a boy becomes a man, the cookie may turn into money, a new car, or a beautiful house. " "It took me many years to understand that the cookie never makes you happy for long. If the cookie is in front of you, you may care for it. But sometimes you may not get a chance to eat it, and then you are busy trying not to lose it. Having the cookie is not what life is about. After having cancer, for me, the cookie starts to lose its meaning. It is the most important that you can live a happy life with or without the cookie, " he said. ,.

Educators across the U.S. are calling for major changes to the admission process in higher education. The National Center for Educational Statistics (or NCES) reported that U.S. colleges and universities received more than 9 million applications between 2013 and 2014 and admitted more than 5 million students. But the problem is not in the number of students, a new report says. The report is called "Turning the Tide -- Making Caring Common." The report argues that the process schools use to choose students causes major problems. David Hawkins is the Executive Director for Educational Content and Policy. He says that most colleges and universities require many things from students when they apply. Schools usually require an essay describing a student's interests or why they want to study at that school. The schools also ask for letters from teachers describing why a student is a good candidate. But, Hawkins says, schools are most concerned with a student's high school grades and standardized test results. The Education Conservancy is an organization that fights to make higher education equal and available. Lloyd Thacker is the Executive Director of the Education Conservancy, saying that the college admission process has changed a lot. "Over the past 30 years, college admissions have become more complex." He says that ranking systems for colleges and universities are a big part of the problem. U.S. News and World Report is a media company that creates a list of what it calls "America's Best Colleges." The company bases the list on information collected from colleges and universities across the country. This information includes results of standardized tests like the SAT from all of a school's students. Higher average test results help put schools higher on the list. Thacker claims, "Too many students are learning to do whatever it takes in order to get ahead, even if that means sacrificing their own individuality, their health, their happiness and behavior..." "The impact on students and on parents is that college is all about where you go. The rank has nothing to do with the quality of education that goes on at the college." The Harvard report states that the best way to change the admission process is by changing college applications. When choosing students, colleges and universities attach greatest importance to _ .

To learn English well you must learn about yourself. You must discover what your own special needs are in English. You should pick out what makes English different from your own language and concentrate on those parts. And above all, you should pick out your own personal weaknesses in English, pick out your own special problems, find out what mistakes you most often make and make a list of them. It will be best if, in your preparation, you can practise doing all sorts of work that you will be asked to do in examination. You should then make a careful note of any mistakes that you make more than once. Count up how many times you make for each mistake, and the mistake you make most often should be at the top of your list, the next most common in the second place, and so on. For example, if your native language is Japanese, you may find the problem of articles comes at the top of your list. If you speak German, you may find using some of the conjunctions is your biggest problem. If your mother tongue is French, you find you are always having trouble with some of prepositions. And if Italian is your language, you may constantly forget to use a suitable pronoun when you should. But these are only examples of mistakes typical of certain languages. They may or may not be your particular personal mistakes. As I say, these personal ones are the most important of all to discover. .The first item on the list should be the mistake you make _ .

People are always talking about "the problem of youth". If there is one--which I take leave to doubt--then it is older people who create it, not the young themselves. Let us get down to something basic and agree that the young are after all human beings--people just like their elders. There is only one difference between an old man and a young one: the young man has a beautiful future before him and the old one has a splendid future behind him and maybe that is where the _ is. When I was a teenager, I felt that I was just young and unknown--that I was a new boy in a huge school, and I would have been very pleased to be regarded as something so interesting as a problem. For one thing, being a problem gives you a certain identity, and that is one of the things the young are busily engaged in seeking. I find young people exciting. They have an air of freedom, and they have not a dull promise to mean ambitions or love of comfort. They are not anxious social climbers, and they have no devotion to important things. All these seem to me to link them with life, and the origins of things. It is as if they were in some sense from outside space and lovely contrast with us suburban people. All that is in my mind when I meet a young person. He may be ill-mannered, self-confident, but I do not turn for protection to boring cliches about respect for elders as if the age is a reason for respect. I accept that we are equals, and I will argue with him, as an equal, if I think he is wrong. From the text we can see the writer's attitude towards the young is _ .

Dear Anne, I like your column very much. I met a girl four years ago at a gym. She was the one who originally approached me and we became good friends. Then one day, she made me really angry, so angry that I just left and we never saw each other again. Looking back, I really regret ending things that way. It was a cowardly act on my part, but I had a terrible temper at that time and let the smallest thing get to me. Recently, I've started thinking about her again and I looked up her e-mail address. I thought about writing to say "Hi" and apologize for what I did but I'm not sure. She could still be angry with me, or maybe she has forgotten me. I feel very lonely and I want to see her again. What should I do? Tom Dear Tom, She may still be angry with you, and she may have forgotten the friendship between you, but that doesn't mean she doesn't deserve an apology. Tom, how many of us have wished for the day that someone who treated us badly saw the light and finally owned up? But we rarely get that kind of expected result. So sure, e-mail her and say "Hi". Tell her you have been thinking about her and just want to apologize for getting angry and being a coward by walking out on her. But you should remember if she thinks you're apologizing just because you are lonely, she might dismiss your sincerity. Therefore, don't mention that. If she wants to see you again, she'll make sure that happens. Even if she doesn't want to be your friend, I can assure you, she'll appreciate the gesture. And it might make you think twice next time you get angry. Anne In the letter, Anne is probably _ .

A four-year study of 200 college students found that those who drink heavily and started drinking at an early age demonstrate poor decision-making skills, just like long-term, chronic alcoholics. Researchers at the University of Missouri-Columbia believe early onset binge drinking negatively affects psychological development. The researches examined college students between the ages of 18 and 22. After three years, they tested them using the Iowa Gambling Test, which measures the tendency to make immediate (disadvantageous) or long-term (advantageous) choices. Based on the students' reported drinking habits, they were grouped into four categories: low binge drinkers, moderate binge drinkers, increasing binge drinkers and stable or high binge drinkers. "Students in the stable or high alcohol use category, who had longer histories of binge drinking, made riskier and less advantageous choices, which reflect problems associated with planning for the future," the researchers reported. The study also found that only students who started binge drinking when they were younger showed impairment on the task. "There is reason to think that heavy binge drinking during adolescence, when the brain is still rapidly developing, may have some negative legacy on psychological development," said Kenneth J. Sher of MU's Midwest Alcoholism Research Center in a news release. "The interesting thing is that if we were to just look at binge drinkers and how impaired they are in the decision-making process as juniors, we'd really be obscuring the important issue, which is how long they've been binge drinkers and / or how early they started." What does the passage mainly tell us?

Penguins can taste only sour and salty food, scientists have discovered. A genetic study suggests the flightless birds lost three of the five basic tastes long ago in evolution. Taste is critical for survival in most animals, but may not matter in the penguin, which swallows fish whole, say researchers in China and the US. Many other birds are unable to taste sweet things, but they do have receptors for detecting bitter and umami (or meaty) flavours. The discovery was made when researchers decoding penguin genomes found some of the taste genes were missing. A closer look at the DNA of penguins revealed that all species lack functioning genes for the receptors of sweet, umami, and bitter tastes. "Based on genetic data, penguins are believed to have sour and salty tastes, but have lost sweet, umami, and bitter tastes," lead researcher Prof Jianzhi Zhang, of the University of Michigan, US, and Wuhan University, China, told the reporter. The umami taste gives food the strong, savoury flavour associated with meat. Lacking this sense is surprising for a carnivorous animal, but does not matter that much in the penguin, which swallows fish without chewing. "Their behaviour of swallowing food whole, and their tongue structure and function, suggest that penguins need no taste perception," said Prof Zhang. "Although it is unclear whether these traits are a cause or a consequence of their major taste loss." The findings, published in Current Biology journal, were a puzzle, he added. One clue comes from the bird's evolution on the frozen ice sheets of Antarctica. Sending signals from sweet, umami, and bitter (but not sour or salty) taste receptors to the brain does not work at very low temperatures. This may have led to the penguin gradually losing its sense of taste, say the researchers. Intriguingly , the sweet taste is missing in almost all birds. The hummingbird, which feeds on sweet nectar, is an exception. Which of the following animals can taste sweet flavour according to the passage?

Wouldn't it be great if you could just look up at the sky and read the weather forecast right away? Well, you can. The forecast is written in clouds. If you can read that writing, you can tell something about the atmosphere. With some practice, you can become a pretty good weather forecaster. Who knows, you might even do as well as meteorologists . Meteorologists use much more information than just the appearance of the clouds to make their forecast. They collect data from all over the world. Then they put it into powerful, high speed computers. This does give the meteorologists an advantage, because they can track weather patterns as they move from west to east across the country. But you have an advantage, too. You can look at the sky and get your data directly. A meteorologist uses a computer forecast that's several hours old to make a local forecast. What are you seeing when you look at a cloud? "A picture of moisture is doing in the atmosphere," says meteorologist Peter Leavitt. There's moisture throughout the atmosphere. Most of the time you don't see it, because it's in the form of an unseeable gas called water vapor. Sometimes, the temperature of the air gets cold enough to cause the waster vapor to change to liquid water. It's called condensation , and we see it happen all the time (for example, when humid air from the shower hits the cold glasses of a mirror). When enough water vapor condenses , droplets come in the air. These droplets scatter light. A cloud is seen. Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come. Changes in clouds show changes in the atmosphere. You should begin to notice patterns. Certain clouds, following each other in order, can signal an approaching storm. But don't take our word for it; see for yourself. According to the passage, an ordinary person might read the weather forecast as well as meteorologists _ .

How Super Are Supermarkets? Buying e week's groceries is tiring. You want to get it over and done with quickly, so you head for the nearest supermarket, you find everything you need under one roof, and you feel glad that those days of going in and out of different shops in the high street are over. Supermarkets seem to be a big plus. There is a downside, though. In the UK 90% of all the food people consume is bought at 5 different supermarket chains. This makes these companies extremely powerful, which lets them use their huge buying power to squeeze small suppliers to get the best deal. Milk is a good example. Supermarkets like to use things like milk, which is the top of almost everyone's shopping list to attract customers. To offer the lowest price possible to the consumer, the supermarkets force dairy farmers to sell milk at less than the cost of production. Supermarkets guarantee their good profits while farmers are left struggling to make ends meet, and the taxpayer pays to support the system without even knowing it. It would be nice if local grocers supported local agriculture. But for the big supermarkets this just doesn't make sense. Supermarkets don't want little farmers thinking they can decide prices. So supermarkets have started a global search for the cheapest possible agricultural produce. In many supermarkets it is difficult to find anything which is produced locally. UK farmers used to grow a lot of apples. Not anymore. In 1999 36% of apples were imported. By 2015 the figure had risen to 80% and the domestic production of apples had fallen by two thirds. The consumer might just be happy to get a reasonably priced meal made up of foods from Thailand, Spain, Italy and Zambia, but we should also bear in mind the Influence on local producers. Then there's packaging. Supermarkets like everything to be packed and wrapped so it can be piled neatly on shelves. Supermarkets produce nearly 10 million tons of waste packaging in the UK every year, of which less 5%is recycled. Some supermarkets make sure that large recycling bins are obvious in their car parks, showing that they are environment-friendly. But that is just an image. When a new supermarket is planned there are claims about the number of new jobs that will be created. Unfortunately, the number of jobs lost in the area is larger than the number of new positions in the supermarket. On average each new supermarket leads to the loss of 276 jobs. However, the modern world is all about shopping, and the freedom to buy whatever you what, so it would be impossible to stop people shopping at some particular kind of shop. But some measures do need to be taken when small suppliers lose profits, local producers suffer, sea levels rise and jobs are lost, anyway, we can't just care about a free car park and special offers. According to the passage, supermarkets keep price advantage by _ .

Bill Gates was born on October 28th, 1955. He and his two sisters grew up inprefix = st1 /Seattle. Their father, William H. Gates II, was aSeattleattorney . Mary Gates, their late mother, was a school teacher. Gates attended public elementary school before moving on to the private Lakeside School in North Seattle. It was at Lakeside that Gates began his career in personal computer soft- ware, programming computers at age 13. In 1973, Gates enteredHarvardUniversityas a freshman, where he lived down the hall from Steve Ballmer, who is now Microsoft's president. While at Harvard, Gates developed a version of the programming language BASIC for the first microcomputer---the MITS Astair. In his junior year, Gates dropped out of Harvard to devote his energies full-time to Microsoft, a company he had started in 1975 with his boyhood friend Paul Allen. Guided by a belief that the personal computer would be a valuable tool on every office desk-top and in every home, they began developing software for personal computers. Gates' foresight and vision have led to the success of Microsoft and the software industry. He plays an important role in the technical development of new products. Much of his time is devoted to meeting with customers and staying in contact with Microsoft employees around the world through e-mail. In the dozen years since Microsoft went public, Gates has donated more than $ 800 mil- lion to charities , including $ 200 million to the Gates Library Foundation to help libraries in North America take advantage of new technologies and the Information Age. How does Gates spend much of his time?

Not very long ago, the question would have seemed absurd. Now it is on the lips of respected scientists; MPs are beginning to talk of "a war on sugar", and even England's chief medical officer has said sugar may have to be, like the old enemy tobacco, taxed in order to protect the nation's health. There came a time in the evolution of public attitudes to smoking, when the doctors had been shouting for long enough that the public was broadly aware of the risks and the only question left,for Government was: what should we do about it? Some believe we are now at the same point in our attitudes to sugar. Others - largely but not only representatives of the food and drink industry - say the entire debate has been skewed, by those who spread stories deliberately to make people nervous. More or less everyone agrees that eating too much sugar is bad for you. There is also no doubt obesity is a growing problem which is putting a significant, avoidable burden on the NHS by increasing the rates of diabetes, heart disease and other long-term conditions. But to what extent is sugar - rather than saturated fats, or salt, carbohydrates or proteins, or any of the other devils of modem diets - the cause of obesity and how much should we worry about it? Yesterday, hopes of achieving anything resembling clarity from the World Health Organisation (WHO) were confused once again, which, widely expected to reduce the recommended sugar intake by a half in new draft guidance, instead said it would continue to recommend that sugar make up no more than 10 per cent of the energy we consume, while adding that cutting this to five per cent would have "additional benefits". The decision will now go out to public consultation. Simon Capewell, professor of the University of Liverpool, said that he suspected "dirty work" on the part of food and drinks companies might lie behind the WHO's less than resounding message. "The food industry say Govemment has no business interfering in families, we must protect personal choice," Professor Capewell said. "We say there is no personal choice. At the moment, a mother can walk into a supermarket with a choice of four tomato soups - with three, or four, or five teaspoons of sugar in them. She has a choice of thousands of ready meals - with five, or six, or even nine teaspoons of sugar in." By referring to smoking the author indicates that

Is there intelligent life on other planets? For years, scientists said "no." or "we don't know." But today this is changing. Seth Shostak and Alexandra Barnett are astronomers . They believe intelligent life exists somewhere in the universe. They also think we sill soon contact these beings(;). Why do Shostak and Barnett think intelligent life exists on other planets? The first reason is time. Scientists believe the universe is about 12 billion years old. "This is long enough for other planets to have intelligent life," say Shostak and Barnett. The second reason is size--the universe is huge. "Tools like the Hubble Telescope have shown that there are at least 100 billion galaxies," says Shostak. "And our galaxy, the Milky Way, has at least 100 billion stars. Some planets going around these stars might be similar to Earth." In the past, it was hard to look for signs of intelligent life in the universe. But now, powerful telescopes allow scientists to discover smaller planets--the size of Mars or Earth--in other solar systems. These planets might have intelligent life. Have beings from space already visited Earth? "Probably not," says Shostak. "It's a long way away. However, intelligent beings may contact us in other way, such as radio signals . In fact, they may be trying to communicate with us now, but we don't have the right tools to receive their messages. However, this is changing. By 2025, we could make contact with other life forms in our universe and we might help each other." Why was it hard to look for signs of intelligent life in the universe in the past?

SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots. City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think. Now San Francisco has found a solution--a phone app for spot-seekers that displays information about areas with available spaces. The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. Monique Soltani, a TV reporter, said she and her sister spent 25 minutes on Friday trying to park. "We were praying to the parking god that we'd find a spot," she said. "If we had the app, we would not have to pray to the parking god." But the system could come with serious consequences. Some people say that drivers searching for parking could end up focusing on their phones, not the road. "It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials acknowledge the potential problem. They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages. If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency. On the app, a map shows which blocks have lots of places (blue) and which are full (red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone but which city officials say they hope to bring to all similar devices. When it is started up, the city's parking app warns drivers not to use the system while in motion. But safety advocates said that might not be sufficient. After all, they say, texting while driving is illegal in California and in many states, but a number of surveys, including one by the Pew Research Center, show that many Americans do it anyway. Elizabeth Stampe, executive director of Walk San Francisco, a pedestrian advocacy group, said she hoped the new parking app would lead to fewer accidents. "It's an innovative idea," she said. "The safe way for people to use the device is for them to pull over, which they know they should do. The question is whether they will." But Ms. Soltani, the TV reporter, said using the app would probably join the group of activities already performed by drivers. "We're already looking at Google Maps and Facebook on the phone while we drive," she said. "Aren't we always looking at something on our phone, or changing the radio, or drinking coffee? You're always slightly distracted when you're driving." According to the text, San Francisco city officials _ .

Antifreeze is a liquid that is added to water to keep it from freezing. When water freezes and turns to ice,it expands .The force of water expanding is so great that it will break the hardest metal.Water is used in car engines to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary. Water freezes at 0degC;the usual kind of antifreeze will not freeze until the temperature is-40degC.A mixture of five parts of water and four parts of antifreeze will prevent freezing at-18degC;four parts of water and five parts of antifreeze reduce this to -22degC. Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol. The text is written to _ .

December usually marks the start of humpback whale season in Hawaii. But experts say the animals have been slow to return. The giant whales are an iconic part of winter on the islands and a source of income for tour operators. But officials at the Hawaiian Islands Humpback Whale National Marine Sanctuary said they've been getting reports that the whales have been difficult to spot so far. "This isn't a concern. But it's of interest. One theory was that something like this happened as whales increased. It's a product of their success," said Ed Lyman. He is a Maui-based resource protection manager and response coordinator for the sanctuary. "What I'm seeing out there right now is what I expected a month ago," said Lyman. He said he was surprised by how few of the animals he saw while responding to a call about a distressed calf on Christmas Eve. "We've just seen a handful of whales." It will be a while before officials have hard numbers. That is because the annual whale counts don't take place until the last Saturday of January, February and March. This is according to former sanctuary co-manager Jeff Walters. "They don't necessarily show up in the same place at the same time every year," Walters said. More than 10,000 humpback whales make the winter journey from Alaska to the warm waters off Hawaii. There, they mate and give birth. Lyman said the whales' absence could just mean they're spending more time feeding in northern waters. That's possibly because of El Nino disruptions. Or it may be because their population has gone up. "With more animals, they're competing against each other for that food resource, and it takes huge energy reserves to make that long migration over 2,000 miles," he explained. What is the passage mainly about?

It's 4 am, and Danilo C. Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum, Sarangani, in the far south of the Philippines. A few minutes later, he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully, figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs, roughly the size of ping-pong balls. He picks them up and puts them in the bucket. Dequina carries the eggs to his hatchery , some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fence. It is here that he buries the turtle eggs he has collected. Today, Dequina scoops a hole, puts the eggs in it, and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carry the hatchlings to the shore, and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free -- most are hunted down by natural predators, and just one percent survive to adulthood. According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction, including four that come to the shores of Sarangani to lay their eggs -- the Hawksbill, Olive Ridley, Loggerhead and Green Turtles. After learning about their plight , Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003. The hatchery drew the attention of the locals. "They started to change their attitudes towards sea turtles," 52-year-old Dequina says. "If they see turtle eggs, they will either bring them to me or inform me of the nesting places." Over the past ten years, more than 3,000 hatchlings have been released to the ocean. What is the attitude of local people toward Dequina's efforts?

Scientist Florence Wambugu works with farmers in Kenya, a country in East Africa. She helps them grow bigger and better crops. Wambugu is especially interested in finding simple ways to produce more food. In the past ten years, Wambugu has spent much of her time studying sweet potatoes, which are an important food in her part of Kenya. A virus kept attacking the plants. It stopped the sweet potatoes from growing well. Because of the virus, some farmers lost three quarters of their crops. Wambugu went to war against the virus. Her research for a way to save the sweet potatoes led to a lab in St. Louis, Missouri. The lab mainly works on genes , the chemical "computer programs" found in the cells of living things. Genes tell a plant to produce pink flowers or an animal to grow black hair. Now scientists have found ways to move genes from one living thing to another. That process is called genetic engineering. Wambugu spent three years in the lab. As a result, she created a sweet potato plant that could fight off the virus. Wambugu tested her research in Kenya, and her plants produced wonderful sweet potatoes. That's just the beginning, Wambugu believes. Genetically modified foods, she thinks, could help farmers in poor countries grow badly needed crops, thus, fewer people will go hungry. What caused Wambugu to set up a lab in St. Louis, Missouri?

What's the strongest part of your body? Your head? Bones? It's your teeth. There is a special thing called enamel in teeth. It is the hardest thing in the human body and keeps bacteria away. However, teeth are hurt easily to problems and disease. September 20 is National Teeth-loving Day in China. Let's pay attention to the health of our teeth. Teeth problems are common around the world. Most children and young adults have tooth decay . A study which come out on China Health Monthly magazine this year showed that 40.74% of a sample of 1,306 Chinese students under age 15 has decayed teeth. Food that is rich in sugar increases the risk of tooth decay. After you eat, bacteria go crazy over the sugar on your teeth. The bacteria turn sugar into acids that eat away at tooth enamel. This causes holes in your teeth. Another common problem is crooked teeth . When your new teeth begin to grow and the old teeth haven't fallen out, there isn't enough space for the new ones. This causes crooked teeth. Don't worry. Here are some ways to keep your teeth healthy. *Brush at least twice a day in the morning and in the evening. *Learn to use dental floss . The floss gets rid of food that's hidden where your toothbrush can't get it. *Visit a dentist. He or she can check if you have any dental problems and help you clean your teeth. *Pay attention to what you eat. It's better to eat lots of fruit and vegetables instead of fries and drink water instead of soda. *Wear braces to make your teeth straight and beautiful. What's the strongest part in the human body according to the passage?

Nobody likes having to deal with an upset child. If your little one is hurt, scared or sad, your heart breaks for her. If she's mad, it can make you mad. You want to be there for her and comfort her, but the best way to do that will depend mainly on two things: why she's upset and how old she is. Be calm and open-minded when trying to comfort your upset child. Try to find out why your child is upset, because that affects how you should respond and what will be most effective in trying to comfort her. Take her aside and sit down to talk on her level, physically and emotionally. Be sure she knows she has your complete attention while she's telling you about the friend who wouldn't share her new toy and so on. Even if you've got 20 other things you need to get done, make yourself take a break and focus on her for a few minutes. Listen carefully to what your child says, and also pay attention to what she's not saying. If she says she's upset because "she hates her stupid school", you must "choose to accept it" -- to read between the lines. Maybe she's struggling with her studies, or the teacher scolded her in front of everybody. Patiently listen and try to _ so you know what kind of problem you're dealing with. Sometimes just knowing someone hears her pain goes a long way toward comforting an upset child. Don't make excuses or blame others, just let her know her feelings are natural and understandable. Give her permission to feel sad for a little bit or even cry a little, and give her a big hug. Then help her think of ways to get over the hurt and refocus her attention on another activity or friend. When faced with an upset child, the parents _ .

I was in my first year of college, making friends and enjoying life, but then my whole world turned upside down. I had a heart attack. It felt like someone was stabbing me in the chest with a knife over and over again. After three months of rest I went back to college, but then things took a turn for the worse. I was staying at my Nana's house and woke up in the middle of the night with a terrible pain in my chest. I knew I was having a heart attack again. I couldn't even shout for help. Luckily my grandpa was going to the toilet and heard me falling out of bed. If it wasn't for him, I probably wouldn't be here. The two holes in my heart were causing the problems and I needed an operation immediately to repair them. Unfortunately, the surgery didn't go well and they only managed to repair one of the holes. When I woke up from the operation, I had a really dry mouth and couldn't wait to have something to eat and drink. The biggest shock of all came when I was told that I needed a heart transplant and was put on the register. The doctors were stunned at how quickly heart failure came on - it usually takes years, but it took my heart less than six months to get to that stage. My whole world came crashing down, but I stayed strong. It was a choice between crying every day and getting on with my life. As time went on, life became even harder. I hated feeling weak all the time and needing help with everything. It got to the point where I thought I would never get a new heart. I was diagnosed with depression. Even though I thought that Christmas 2008 would be my last, I really enjoyed it and even had a good New Year. Everyone was crying for me when the clock struck midnight and they told me to keep fighting. A week later, I got a call from the doctors saying they'd found a suitable donor . My wish came true and thankfully the operation went well. I spent four hours in surgery where they took out my old heart and put a new one in. When I woke up I burst out crying. I had a second chance at life. When the author learned that he needed a heart transplant, he _ .

LONDON (Reuters) -- Children are dying for lack of drugs tailored to their needs, according to the World Health Organization (WHO), which launched a global campaign on Thursday to promote more research into child medicine. More than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters. The problem is even worse in developing countries where price remains a major barrier and 6 million children die each year from treatable conditions. In the case of HIV/AIDS, the few existing pediatric therapies developed for children generally cost three times more than adult ones. As a result, clinicians lack clear guidelines on the best drug to use and often have to guess at the correct dose. Fortunately, the WHO has drawn up the first international List of Essential Medicines for Children, containing 206 products considered safe for children. "But a lot remains to be done. There are priority medicines that have not been adapted for children's use or are not available when needed," said Dr Hans, the U.N. agency's director of medicines policy and standards. Medicines that need to be adapted to children's needs include many antibiotics, pain drugs as well as combination pills for HIV/AIDS, tuberculosis and malaria. The agency is building an Internet entrance linking to clinical trials carried out in children and will launch a Web site with the information early next year. Testing medicines on children has always been a controversial issue, since good ethical practice requires informed agreement from people participating in clinical trials, which is difficult to obtain in the case of children. As a result, research-based drug companies have been _ of developing child-friendly medicines and general companies have been slow to produce them at lower cost. In an attempt to deal with the issue, both Europe and the United States now have special rules offering extended patent protection for drugs that have been tested on children. Why has testing medicines on children always been a controversial issue?

"Can I hug you?" community nurse Joyce Jebambula asks with a smile as she welcomes me back to her village. "Of course," I say as I put my arms around her. It's an unbelievable moment. Just at the height of the outbreak more than a year ago, there was an "avoid body contact" rule here. It's now been removed. One of the most challenging parts of reporting this outbreak over the past 18 months is that I haven't been able to touch anyone in the worst-affected countries. When Ebola survivors described in tears describing losing their families, I had to almost sit on my hands to avoid reaching out to comfort them. The outbreak was declared over in Sierra Leone on 7 November. I returned for the celebrations. But despite reaching this long-awaited milestone, all is not well. Ibrahim Koroma, 21, clings to his survivor's certificate outside the home. All 17 of his family are now dead. The certificate is one of his most prized possessions. "He does not pose any risk to the community" it reads. Ibrahim tells me how his landlord has allowed him to stay in one of the rooms of his former family home until the end of the year. He says he doesn't know what he'll do after that. He does some part-time work, relying heavily on help from neighbours. His two little sisters and little brother died in the very room where he now sleeps. He says he often lies awake thinking about them, feeling very bad. The Ebola outbreak in West Africa was the worst on record. In past outbreaks there had only been a few hundred deaths and a few hundred survivors. It was thought Ebola could live for only three months. But research has now shown it can linger for at least nine months. Scientists are still trying to find how long it could be infectious. When interviewing Ebola survivors the author _ .

Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer? People have been wondering why elephants do not develop cancer, even though they have life spans that are similar to humans, living for around 50 to 70 years. Now scientists believe they know why. A team at the University of Chicago, Us has found that elephants carry a large number of genes that stop tumors from developing. To be precise, they found 20 copies of an anti-tumor gene called TP 53 in elephants. Most other species, humans included, only carry one copy. According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal's sensitivity to DNA damage. This lets the cells quickly kill themselves when damaged before they can form deadly tumors. "An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals," study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous, large creatures with long life spans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass. _ was found by Oxford University scientist Richard Peto in the 1970s and later named "Peto's paradox". Evolutionary biologists believe it results from larger animals using protection that many smaller do not, In the elephant's case, the making of TP53 is nature's way of keeping this species alive. The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place. "Nature has already figured out how to prevent cancer," said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US. "It's up to us to learn how different animals tackle the problem so we can use those strategies to prevent cancer in people." According to Dr. Vincent Lynch, what has been a risk in the evolution of large animals?

Do you like listening to music? Do you often turn up the music when you're using earphones? If so, your hearing may have been damaged . The World Health Organization (WHO) is worried that 1.1 billion children and young people are damaging their hearing by listening to loud music. Nearly half the young people in developed countries may lose their hearing because of the "unsafe use" of music players, including smartphones. Loud music in nightclubs, parties and at sports also make it worse. The WHO advises young people to listen to music for just one hour a day. Dr. Etienne Krug told BBC: "What we're trying to do is to draw people's attention to a problem that is not talked about enough." He said it's easy to solve this problem. Dr. Krug said keeping the music down and limiting the listening time to less than one hour a day would save a lot of people's hearing. However, he also said, "Even an hour can be too much if the music is too loud." Ralph Holme, a researcher, explained how loud noise can damage ears. He said: "Loud sounds damage your hearing by killing off thousands of little hair cells in the inner ear. The cells can tell different sounds through vibration . But they are very _ --they get damaged easily and even die if they vibrate too much because of loud sounds for too long." He warned: "The bigger problem is they don't grow back and the ear can no longer get sound." No one wants to lose their hearing! Therefore, next time when you listen to music, make sure it's not too loud and only listen for less than an hour. You can enjoy your music much better in this way. How long does WHO advise young people to listen to music a day?

Health insurance can be very expensive. Some working people do not make enough money to pay for it. In the US there is a program called Healthy Families. This program offers people health insurance at a low cost. Families are charged about Y=7.00 a month for every child, and Y=10.00 for every adult. It costs much less than any other kind of health insurance. Having health insurance is very important. With this insurance, people can see a doctor when they are sick or hurt. The program is not expensive at all, but many people are still not enrolling in it. People say that it still costs too much money. They need all of their money to pay for things like food and rent. It would be great if everyone could have health insurance. People are working hard to come up with ways to make this happen. One idea is to make the Healthy Families Program free for some people. It is important for people to see a doctor when they need to. The Healthy Families Program makes it possible for more people to do this. Many ideas are being considered. Hopefully some of them will allow even more families to get health insurance. The Healthy Families Program is made to help those who don't have welfare and cannot earn enough to pay for private health insurance. It is an important program, but officials say that too many people are signing up for it and then dropping out because of the Healthy Families Program's cost. If a couple has two children, how much would health insurance cost every month in the family?

Dear Anne, I like your column very much. I met a girl four years ago at a gym. She was the one who originally approached me and we became good friends. Then one day, she made me really angry, so angry that I just left and we never saw each other again. Looking back, I really regret ending things that way. It was a cowardly act on my part, but I had a terrible temper at that time and let the smallest thing get to me. Recently, I've started thinking about her again and I looked up her e-mail address. I thought about writing to say "Hi" and apologize for what I did but I'm not sure. She could still be angry with me, or maybe she has forgotten me. I feel very lonely and I want to see her again. What should I do? Tom Dear Tom, She may still be angry with you, and she may have forgotten the friendship between you, but that doesn't mean she doesn't deserve an apology. Tom, how many of us have wished for the day that someone who treated us badly saw the light and finally owned up? But we rarely get that kind of expected result. So sure, e-mail her and say "Hi". Tell her you have been thinking about her and just want to apologize for getting angry and being a coward by walking out on her. But you should remember if she thinks you're apologizing just because you are lonely, she might dismiss your sincerity. Therefore, don't mention that. If she wants to see you again, she'll make sure that happens. Even if she doesn't want to be your friend, I can assure you, she'll appreciate the gesture. And it might make you think twice next time you get angry. Anne Which of the following is what Anne advises Tom to do?
