It's not about how much money you make, and it's not about who your daddy is. And no, it's definitely not about whether you look like Tom Cruise or his wife Katie Holmes ... What it is about is these simple things, things that maybe even a person like Tom Cruise does not have. We're talking about being attractive in general, whether it's on a job interview or just gaining the respect of your colleagues. Ask lots of questions In other words, be humble. If you come across as a know-it-all (even if you really do know it all!), it really pushes people away. Rather, asking lots and lots of questions (even dumb ones) makes people feel like you care, you can be trusted, and you are... humble. Stay busy Do you really know the power of this? We're told to stay busy to prevent depression and feelings of anxiety. But did you know you should also stay busy to be really attractive? It's true. Always have something to do. Have you ever seen someone just sitting around, doing nothing? How unattractive. Always be busy with something, even if for some reason you have to make something up. Show your pearly whites (or just smile) Smile more, no matter how ugly your teeth are. I'm not kidding about this one. It's not all about the teeth. If you are smiling genuinely, you can draw everyone for 100 meters around to you. Be interested in other men Be interested in the other person. Again, ask them questions. Don't talk about yourself... remove attention from yourself. If you are truly interested in the person, it will come across. And if you want to talk about yourself, you'll find that putting the other person first actually opens him up to return the favor and ask you questions. See how fun this is? So, yes it is possible to be the most attractive person in the world. If you've noticed the ring throughout the article, it has a lot to do with just being confident in who you are. Nobody needs to look like Tom Cruise or Will Smith or their wives, or anyone else for that matter. Every person, of every race, of every nationality, of every background, can be the most attractive person in the world. The main idea of the article is to tell us _ .

Every school has an ugly girl. In my primary school, it was me. From first grade through fourth, I had to wear heavy orthopedic shoes because of my weak ankles. I sounded like overweight elephant wearing bricks whenever I took a single step. "Hey, Bigfoot!" "Geez, you're going to start an earthquake!" Then in sixth grade I had to start wear glasses. Mom asked for the least expensive ones and that made me look like a fool. "Four eyes!" "Couldn't you cover up more of your faces? Why stop at the eyes?" In Seventh, I started competing on the city swim team, thinking that if I got a killer body, nobody would notice my face. Wrong again. I loved being fast and winning ribbons now and then, but now I had red, wet eyes from the chlorine in the pool. I also did not develop a killer body. I changed my strategy at Eighth grade, the last year of middle school. I offered my help to anyone who needs. I worked for other girls, so they could hang out with their friends. My new program began to work. People who would never have acknowledged my existence before were suddenly seeking me out. I'd been feeling pretty good until one day I went to Christine's house to help her fill envelopes. Going into each envelope was invitation to Christine's birthday party; it was a big event at a fancy hotel. Complete with dinner. She asked me to help her address these envelopes. There was no envelope for me. My heart was broken. I tried to escape from all the eyes. High school had to be better, right? Yes and no. Now that I'm here, I know there are still lots of shallow people judging you on what you're wearing or how cool your hair is , but there are also kids who talk to you because they liked your answers or just as you're kind, honest, and a good friend. I still do kind things because I like the feeling I get when I am helping people. I, with my friends, went to Children's hospital, playing games and reading to the sick kids. I still had wet red and not a smart look, but you cannot tell me I am not beautiful. Every time I visit hospital, five-year-old Terry grasps my hand, "Morri, you are so nice. I want to grow up to be just like you." Which of the following is the real reason for Morri competing on the city swim team?

Now net fiction ,also called computer fiction is popular in more than 80 countries. To write computer fictions,the writers don't have to think about making any plot.Like reporters,they just go to a lot of places and collect materials:what most women want,their ideas about life and love,their happiness and sufferings and emotions.All these materials are fed into the computer to be processed and classified .Then the writers just pick some materials from every part and fill in some details and a story is made up. The first computer fiction was edited by 13 editors and published in Canada in 1976.It was a great success and 45 million copies were sold.Seeing this new process as profittaking a big American publishing company bought over the majority of the 13 Canadian editors and soon a series of computer fictions were published in the United States. All the computer fictions have very romantic titles.The heroine is always about 20,while the hero is a 30 to 40 bachelor ,handsome,with money and power.The hero and the heroine have a happy reunion after all kinds of misunderstandings .Computer fictions are enjoyed by most women readers of the west.But people doubt if they have any literary value . How do computers write fictions?

I was painfully shy as a child. In high school I would avoid participating in class discussions. I was too afraid to talk to anyone but my closest friends~ I would think about being less shy, wanting the courage not only to ask a girl out, but to speak up in class and say what I was thinking. Yet, it never happened. Fears showed themselves in such self-conscious questions as, " What will other people think? What if she says no?" I felt a dark presence in my mind holding me back. This shyness continued into college. One day, the question occurred to me: Is life shy? The thought surprised me ! Think of the leaves bursting out in the spring time, the bird singing at dawn, the sheer number of different forms of life, all expressing the wideness and scope of divine life. There's nothing shy about it. Life is everywhere and attention-grabbing . So, if my creator isn't shy about all the life that needs expressing, I don't need to be either. I realized that if I wanted to overcome fear and shyness, I would have to put this law of life into practice~ Shyness, fear, and loneliness were hindering me from living my life as life: God wanted me to live it. Therefore, I decided to live how life saw me. One example: I wrote a note to a girl, asking her out on a date. Even as I was writing it, the fears of disaffirmation and unworthiness came to me. This time however, instead of shrinking back and hiding from the fear, I put the note in the campus mail in spite of myself. I thought: whether she says yes or no, it's still right for me not to be shy. I can live with the confidence sent from the source of my life. The girl saw me in class the next day and told me that she would love to go out with me. I should not have been so surprised! Bit by bit, I was proving that the limited view of myself no longer had control over me. After college, I worked as a newspaper reporter, earned an advanced degree in theater, became a productive writer (a lifelong dream), met a special woman whom I married, and even got a job teaching at a university. The purpose of writing the text is to _ .

A smile will tell people around you that you are a kind and friendly person. However,many people don't smile because they think they ugly teeth. For example, one of my classmates, Mile, doesn't have very nice teeth,so thatis why he seldom opens his mouth.he even says that he has lost cofidence because of his teeth.So it is very important for us to look after our teeth. In fact, a lot of people have this problem.Some people inherit teeth problems from their parents,while others'teeth are damaged because of bad habits,like heavy smoking,eating too much sugar or not brush-ing teeth often.If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of then. Smiling can help you to feel more confident and make other people think of you as a more friendly person. If you want to keep healthy,you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 300 times a day, wile adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now! ,. If you want to keep healthy, you had better _ .

Chinese people are now spending more time surfing the net than watching TV, according to results of a survey by the Chinese Academy of Social Sciences (CASS) published Thursday. The survey, of citizens of five Chinese cities, found that 79 percent of interviewees use the internet for information, and 55.1 percent to read news on the internet. About 63 percent of the interviewees use e-mail. The average times spent surfing the net and watching TV were 2.73 hours and 1.29hours, respectively. Only 10.4 percent reported use the internet primarily to send and receive email; 65.9 percent read online news; 62.2 quite often play games on-line. More and more people have taken an interest in the entertainment opportunities online. Up to 56.5 percent of interviewees quite often download music, and 53.5 percent get entertainment messages from the internet. Yet the survey found that television is still the dominant mass medium. Seventy-nine percent of interviewees choose to watch TV to get information, and another 75 percent take newspapers as important as TV. Five major web sites in the Chinese language, namely Sina, Sohu, Netease, Baidu and Yahoo are still ranked top ones by web users, and those that voted for Sina as the best among them were 30.9 percent. Authorized statistics showed that web users in China have already 100 million, second to that of the United States. Which of the following is not true?

What was your favorite sport during your childhood? Maybe running around the playground or jumping rope for hours would bring you pleasure. At that time you weren't thinking of health, you were just thinking of entertainment . But in this age of high-tech home equipment, the simple joy of jumping rope has been forgotten. I think rediscovering it probably will give you a total-body exercise. Although considered an excellent form of exercise, jumping rope has never been widely accepted because of two reasons. First, most people consider jumping rope to be an excellent form of cardiovascular exercise, but they also believe that it is simply too difficult. In other words, they don't think they'll be able to continue jumping for the near 20 minutes in order to achieve a beneficial physical effect. Second, many people regard it as a little boring and overly repetitive --not as something fun or enjoyable. _ . Instead of doing the usual two-foot bounce over and over again, players good at rope-jumping often change their pattern every 10 or 20 jumps. A single bounce, a double -bounce, a skip, a knee-up, side swings, as well as a variety of other easy-to-learn free-style rope-jumping . Nowadays researchers are discovering that jumping rope also prepares the brain for learning. It is an exercise allowing both brain hemispheres to perform equally to each other . In a word, jumping rope can be a life-long activity requiring little equipment, time and space, yet leading to a much healthier life. One reason that can explain why rope jumping has not spread widely is that _ .

The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms. After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London. Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London. "The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire. At the peak of the cycle, violent outbursts called coronalmass ejections occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots. Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available. The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares and explosions as they occur. Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. _ What can be inferred about the solar activity described in the passage?

Every time you go online you leave a digital footprint. This is just like a real footprint. It tells where you have been, how long you stayed on line and what you have been doing there. It's easy to get the information and show your digital footprint every time when you send an email, messages and photos. You shouldn't worry about it too much but it is better to be careful about your digital footprint when you are online. There are five tips for taking care of your digital footprint. Don't forget to close the pages with your information when you leave a website, especially if you are using a shared computer. Don't tell anyone your password and don't write them down in a place that everybody can see. Make them more difficult by using both letters and numbers. Remember your favourite websites by looking over the history and the bookmark on your computer or your mobile phone. This is a way that your digital footprint can work in your favour, remember to clear your history from time to time. If you want to post some words on line, you don't have to use your own name. You can use a nickname instead. You can also use a picture instead of a real photo. Protect your personal information online. Be careful about who you share your own information with and always think twice before sharing email, home address, school or phone number with someone. All kinds of people are interested in your digital footprint. It's now quite common for people to look over some personal information online before they offer someone a job. There are cases of people having missed out on jobs and places because their digital footprint didn't make them look good. So remember: keep safe, don't put too much personal information online and always think carefully before you post something. Ask yourself, 'would I be happy for everyone to see this?' How do you leave a digital footprint?

Howling is a behavior commonly observed among a wolf pack . As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There are different explanations of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bond better together. It's almost as if howling together helps the pack stay together, perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behavior. Indeed, there have been times when wolves have been seen one moment howling in a chorus, and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be "punished" for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status among its members? --Why do wolves howl for sure? What is clear, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering. Howling, interestingly, is a contagious behavior. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of "roll call" where wolves all howl together to report their presence. What is the possible similarity between wolves' howling together and human's singing in chorus?

Remember, from the moment they are born, our children have the ability to know when they are hungry - and they cry to let us know too! Of course, they also cry to let us know they are wet, hurt, or bored, but we soon learn to tell the difference and try to meet each need somehow. When we begin to feed them solid foods, they let us know when they have had enough by turning away from the spoon - or refusing the food back at us! Why is it that once children are old enough to sit at the table their parents are often heard bargaining with them or threatening them to finish all their dinner? When we make our children eat up the plate that we filled, we don't pay attention to their born ability to know how much, and what, their bodies need. Instead, we should allow them to use their own hunger feelings to determine how much they need, while we provide a balance of nutritious and "fun" foods. When we teach them about moderation and set a great example by living an active, healthy lifestyle, they will be less likely to develop weight problems later in life. Think of your slim friend who eats whatever she wants -but will refuse ice cream if she has had enough to eat! "Eat all your dinner if you want dessert" translates to "you must overeat so I will reward you by letting you overeat some more!" By using sweets as a reward for good behavior, kids begin to believe sweets are really special and they may want them even more. Instead, by making dessert just another (small) part of an enjoyable meal, kids learn to "save room for dessert" instead of becoming a member of the "clean plate club." If you are one who eat enough but still stay slim, you may _ .

Teenagers are often a difficult group. With all those hormones flooding their bodies, they can be moody, unpredictable, and tend to make uncertain choices. But however confusing their teenage years are, kids can still be generally happy, depending on their lifestyle choices. According to a new research by British scientists, teens who don't smoke, drink only moderately or not at all, and who don't eat much junk food are likely to be happier than other teens. The study looked at 40,000 British families and came up with some interesting findings. For example, kids who never drank alcohol were up to six times more likely to report higher levels of happiness than kids who drank. And teens who smoked were five times less likely to rate high on happiness charts compared to kids who don't smoke. Same goes for diet and physical activity. The more fruits and vegetables kids eat, and the more hours they spend playing sports, the happier they are. Now, of course this doesn't mean that not smoking or drinking, and playing sports guarantees happiness. It could be that kids who have happy character tend to be more active and less addicted to drinking or smoking. And it could equally be the case that kids who are unhappy are more related to drinking and smoking and eating junk food. Other studies have shown that exercise is a proven way to treat anxiety and depression. Future studies may support the idea that other healthful behaviors, including refraining from smoking, drinking, and eating too much junk, can avoid sadness and increase happiness, too. Which can be the best title for the text?

"We're going to move," Jimmy said to Mr. James,her teacher, with tears in her eyes. "Dad lost his job and now we don't have enough money to live in our house." Pam was walking by and just heard Jimmy's talk with Mr.James. In the lunchroom Pam met Carol and said, "I've got something to tell you about Jimmy."

Try some amazing tea recipes to get, started. Almonds Almonds are a great afternoon recharger that research from Purdue University shows will also aid in your weight-loss efforts. This is because almonds provide sustained energy: a mix of fat, fiber, and protein.Those elements allow almonds to offer a convenient snack that gives you a smooth shot of energy that comes from controlling your blood sugar levels. Plus, research shows that people who regularly eat nuts have as much as a 50 percent reduced risk of having a heart attack. Greek Yogurt Research from the University of Missouri shows that protein helps your body into better blood sugar control by stimulating the release of the hormone glucagon . Aim for a cup that has 20 t0 23 gram.s of protein for your snack. Dark Chocolate Despite often being viewed as a bad dietary food, dark chocolate can help fight off that urge to take a nap in the middle of the day. While dark chocolate does contain small amounts of caffeine, its real power comes from phenyl ethylamine . Research from Middlesex University in London shows that just smelling chocolate can shift brain activity towards greater attention. The passage mainly talks about _ .

More than half of the parents in the United States are helping, or have helped, support their adult children who have been hit by high unemployment and poor wages , according to a new survey. It showed that present economic conditions are discouraging young adults from leaving home and forcing those who have already gone, so-called boomerang kids, to return. "Parents are continuing their financial involvement longer than we expected," said Ted Beck, president of National Endowment for Financial Education (NEFE). About 60 percent of parents questioned in the survey said they're helping their adult children who are no longer in school financially. Half are providing housing and nearly half are helping with living expenses. For an increasing number of adult children, the situation is bad. Two-thirds of adult children, aged 18 to 39, who are not in school said they faced tougher financial pressures than previous generations, according to the survey. And nearly one-third of parents agreed that it was easier for them to find their financial feet than for their children. Parents are helping their children out of genuine concern because they do not want to see them struggle. But Beck said that parents who make sacrifices to help their adult children should be careful about their own finances. "If you are taking on extra debt or delaying retirement to help your adult child, you could be making a mistake and putting your own financial future in danger," Beck warned. Boomerang children can also cause other problems for their parents. Thirty percent of parents said they had given up privacy since their adult children moved back home, while more than a quarter have taken on added debt, and seven percent have delayed retirement. But the survey also showed 42 percent of adult children living at home are helping with the cooking and cleaning. What is Ted Beck's suggestion to the parents?

John von Neumann was the oldest of 3 children of an banker, and his speed of learning new ideas and solving problems stood out early. At 17, his father tired to persuade him not to become a mathematician because he may lead a poor life being a mathematician, and so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph.D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry. In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics(Einstein was one of the others) World War II hugely changed von Neumann's areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematics theories into practice. During the last part of the war he became interested in computing machines and made several fundamental contributions After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died in 1957 of cancer. Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20th century. Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving ability is a part of his legend. He reported one accident this Way: "I was driving down the road. The trees on the right were passing me in an orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path." von Neumann published his first book at the age of _

Not all vegetables need lots of sunshine. Mark Hoffman and his wife own a bed-and-breakfast guesthouse in rural Kempton, Illinois. They often serve their guests fresh products from the garden. The Hoffmans have been growing food and flowers for twenty-five years. For almost ten of those years, Mr. Hoffman has been experimenting and working with shade plantings. He says, "The bottom line here is that most plants will produce more in full sun. But if you do not have full sun, there are other choices." For example, he grows tomatoes near oak trees. Oak trees can produce a lot of shade. But Mr. Hoffman says his tomato plants grow as long as they get five hours' direct sunshine a day, especially morning sun. Not only does this go against the traditional advice that tomatoes need six, eight, even twelve hours' full sun a day. It also shows how plants and tree roots can share nutrients and water. Mr. Hoffman says plants with wider leaves seem to do better in shady environments. He also found that his potatoes did better partly in shade than in full sun. Moving them out of the sun helped control an insect problem. Mr. Hoffman does not use pesticide . Instead, he planted the potatoes in the shade, especially on the east side of the tree. The potatoes get morning sun, but they are shaded during the hottest part of the day. Some insects dislike shade, and the hottest part day is when they do the worst of their damage. Time of day, sun intensity , shadows from trees, walls and buildings all influence how much sunlight falls on plants. And people interested in shade planting should also remember something else. The term "shade" can describe different amounts of darkness. It can even mean different things in different parts of the world. How many hours of sunshine are enough to keep tomato plants growing in Hoffman's garden?

Apollo 11, carrying Neil Armstrong, Edwin Aldrin and Michael Collins, was launched on 16 July, 1969. Five days later they stepped down onto the moon. Neil Armstrong On the way there: Of all the wonderful views we had, the most impressive to me was on the way to the Moon when we flew through its shadow. We were still thousands of miles away, but close enough so that the Moon almost filled our window. The moon appeared blue-grey. It seemed almost as if it were showing us its roundness, its similarity in shape to our Earth, in a sort of welcome. I was sure it would be a hospitable host. It had been waiting for its first visitors for a long time. After touch down: The sky is black, you know. It's a very dark sky, but it still seemed more like daylight than darkness as we looked out the window. It's a very strange thing but the surface looked very warm and inviting. It seemed to be tan . It's hard to explain that, because later when I held the material in my hand, it wasn't tan at all. It was black, grey and so on. Edwin Aldrin On the Moon: The blue color of my boots has completely disappeared now into this soil--still don't know what color to describe this other than grayish cocoa. Back on board: The moon was a very natural and pleasant environment in which to work. On the Moon, in one-sixth gravity, you have a strong feeling of being somewhere. As we did our experiments, some objects we threw away would go in a slow, lazy manner. Edward Aldrin described the soil as _ .

See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting "print" on your computer. You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape. Instead of ink, the materials the 3D printer uses are mainly plastic, resin and certain metals. The thinner each layer is--from a millimetre to less than the width of a hair--the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it. Last year, though, saw a big change in the 3D printing industry--printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost PS20,000, while now they cost only about PS1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of--flutes , bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one. However, as 3D printing becomes more common, it may bring about certain problems--such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils on your personal 3D printer, who will visit a retail store again?" an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun? What is the best title of the passage?

In the universe,as we all know,there is the sun,the moon,the earth and a good manystars.Through our geography lessons,we know the earth goes around the sun,and the moon goes around the earth.We have day and night because the earth keeps turning all the time.When our part of the earth turns to the sun,it is day.When our part of the earth turns away from the sun,it is night. Just because the moon is closer to the earth than the sun, it looks much bigger than the sun. Big things will look smaller when they are further, and small things also look bigger when they are nearer. The sun is big enough to give out very strong light. The moon can't give any light at all, but it looks quite bright, too. Why? In fact, the light from the moon comes from the sun. The moon looks much bigger and brighter than the stars. But actually the stars are much bigger and brighter than the moon.They look smaller than the moon also because they are further away from the earth. There are many other planets in the universe. But of all the planets, only on the earth there are living things and people can only live on the earth, too. But at 9:00 a.m. on October 15th,2003, Chinese pilot Yang Liwei was sent up to space.

Donald Watson was a man who thought very much about the food he ate. He was born in yorkshire, England , in September 1910. And he died in November 2005, at the age of 95. That is a very great age. Watson explained that it was because he never ate any food from animals. When he was a boy , Watson stayed on a farm. .He loved to see the animals. He said that they gave so much to people. And all the animals were so friendly. Then , one day , he saw a man killing a pig . He was very sad. . From then on, Watson decided that he would never again eat meat . Twenty years later he decided that he wouldn't eat anything from animals, such as milk, cheese or eggs. He became vegan . Watson formed a group called "The Vegan Society". In its newspaper, The Vegan Society thought it was terrible and wrong to eat food from animals. At first, there were not many people who agreed with him . They thought it was crazy to do _ .Most people thought it was too difficult and unhealthy. However, over time , more and more people began to agree with Watson and The Vegan Society. People become vegans for many reasons. Watson and his friend stopped eating because they loved animals. They believed that it was wrong to hurt another living thing . Now, people also become vegans for environmental reasons. Keeping animals takes a lot of resources , including water and food. Also, in some places, people are cutting down trees to create more land for cows. By avoiding food from animals, vegans hope to protect these forest areas. Finally, just like Watson, some people believe that being a vegan is healthier. They believe that food from animals causes heart problems, a high body weight and many other health problems. We know from the text that Watson _ .

Old age may not sound exciting.But recent findings offer good news for older pepole and for people worried about getting older. Researches found that people become happier and experience less worry after they reach the age of fifty.In fact,they say by the age of eighty--five,people are happier with their life than they were when they were eighteen years old. The findings came from a survey of more than 340,000 adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time,the people were between the ages of eighteen and eighty--five.The searches asked questions about emotions like happiness,sadness and worry.They also asked about mental or emotional stress. Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty--two and twenty--five.The findings showed that stress levels dropped sharply after people reached their fifties.Happiness was highest among the youngest adults and those in their early seventies.The people least likely to report feeling negative emotions were those in their seventies and eighties. The study also showed that men and women had similar emotional patterns as they grew older.Hower,women at all ages reported more sadness,stress and worry than men.Researchers say they do not know why happiness increases as people get older.One theory is that,as people grow older,they grow more thankful for what they have and have better control of their emotion .They also spend less time thinking about bad experiences. The researchers also considered possible influences like having young children,being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well--being related to age. How did the researchers find older people happier?

In north America people are always in a hurry.Children have special lessons or sports activities after school.Parents often work late and don't get home until 7 or 8 o'clock at night.More than 50% of women work at full-time jobs,and many people do part-time work.Most North American families don't have time to eat many meals together. When a family takes the time to eat a meal together,often there isn't enough time to prepare the food That is why "fast food "is so popular in North America.People spend about 40% of their dollars on fast food. Fast food is food such as pizza, sandwiches or fried chicken.People usually buy the food from a restaurant chain such as Pizza Hut,McDonald's,or Kentucky Fried Chicken.Fast food saves time,but it is not very nutritious . Fast food is popular in many countries.American fast-food companies now have restaurants all over the world.But not everyone is happy about the spread( of North American fast food.A group of people in Italy want to fight against it.They do not want any more fast-food chains to open restaurants in their country.They also want to fight against the spread of fast food everywhere in the world.

When we buy a house, we all want to have nice neighbours, because most of us think that it is helpful to live with some good neighbours. But what kind of neighbour is good? The answers are different from people to people. Here are my answers. First, it is very important to respect each other. If our neighbours try to know more about our life, what will we feel? He or she may also talk with others about our life. Do you want to live with him or her any more? The answer is "No". We will feel very sad to have this kind of neighbour and move away quickly. Next, a good neighbour is always ready to give us a hand when we need him or her. For example, if we are not at home, our good neighbours will watch our house for us. Finally, a good neighbour should love the environment . He or she never puts rubbish here and there. Good neighbours should keep the place clean, because the good environment can make us comfortable and happy.

Dolphins are not fish. They are mammals .They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain is as big as men's and they live a long life at least 20 or 30 years. Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to receive sounds,but use the jaw--the lower part of the mouth. It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand,there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903 ,Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat of the Penguin. Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them.

The Friday after the American holiday of Thanksgiving is called Black Friday. It's said that it's the day that store ledgers move into the black and companies become profitable. On that day, retailers slash prices to get consumers to buy. It is also a time when many Americans start their Christmas shopping. VOA's Elizabeth Lee tells us how the economy may affect consumers on that bargain day. This day should be a shopper's dream. "It's just the deals, the sales and everything you can get for a lesser price," said Sandy Thomas, a shopper. But it's a nightmare for others. "I think it's crazy. I've done all of my shopping throughout the week so I don't have to go out on Friday," she said. It's called Black Friday, the start of the traditional Christmas shopping season in the United States. Every year it's the day after the Thanksgiving holiday. Stores open before sunrise and there are deep discounts everywhere you look. Last year a crowd of bargain-hunters killed a Wal-mart worker in a New York suburb. This year, many stores are increasing security while they slash prices. "This is a huge time for the retail stores," said Fred Joutz from George Washington University. "This is when they begin making their profits for the year." Economics professor Fred Joutz says how Americans spend the weekend after Thanksgiving is a good indication of how consumers feel about the future. With the unemployment rate above 10 percent, Joutz says Americans are saving more and spending less. Some retailers are attracting consumers by opening on Thanksgiving Day, when shops are traditionally closed. Other stores open their doors anywhere from midnight to four in the morning. And shoppers will be lining up in front of the doors in order to be one of the first ones to walk through and get a big discount. Electronics like flat screen TVs are usually the first items to go. Sandy Thomas says it's an annual family tradition and well worth it. "I just save maybe half of what I would have spent on a regular, you know, shopping trip," she said. Economists say U.S. consumers will spend money this Black Friday, but they will spend it more carefully. Why are many stores increasing security according to the passage?

It is not always easy to understand inventions and new developments in science. To understand fiber optics , however, you can try an experiment. Put a drop or two of milk into the glass of water. Turn off the lights. Shine the light from your flashlight through the top of the glass at an angle of about 45 degrees. Put a piece of white paper against the glass when the beam of light is shining. Move the paper so you can see where the beam is coming out of the glass. You should see a spot of light. Some of the light has passed through the water and through the glass. You see it on the paper. You also see another beam going down into the glass. It is being reflected down into the glass. Next move the flashlight so that the beam is coming straighter down(30 degrees) into the water. You will see the same phenomenon: some of the light is reflected back into the glass. And some escapes out. Now move the beam of light from the flashlight slowly up until you cannot see any light escaping. This point is called the "point of total internal reflection." The word internal means "inside." All the light is staying inside the glass. There is no beam showing a bright spot on the white paper. All the light energy is inside the glass. The glass of milky water is like a strand of glass. A fiber optic tube is a bundle of long thin strands of glass, really many tubes. However, the principle is the same: at a certain angle, all the light energy that goes into the glass fiber comes out the other end. Light is energy. Sound is energy. Radio waves and electricity are both energy. They can all be changed into light, and as light they can all travel along a glass fiber. Light travels at the rate of 186,000 miles per second. Therefore, a message can travel that fast in a glass fiber. This is the principle, or law of nature, that makes fiber optics work. The last step is to prove_.

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

EDGEWOOD-Every morning at Dixie Heights High school,customers pour into a special experiment:the district's first coffee shop run mostly by students with special learning needs. Well before classes start,students and teachers order Lattes,Cappuccinos and Hot Chocolates.Then,during the first period,teachers call in orders on their room phones,and students make deliveries.By closing time at 9:20a.m.,the shop usually sells 90drinks."Whoever made the chi tea,Ms.Schatzman says it was good,"Christy McKinley,a second year student,announced recently,after hanging up with the teacher. The shop is called the Dixie PIT,which stands for Power in Transition.Although some of the students are not disabled,many are,and the PIT helps them prepare for life after high school.They learn not only how to run a coffee shop but also how to deal with their affairs.They keep a timecard and receive paychecks,which they keep in check registers. Special-education teachers Kim Chevalier and Sue Casey introduced the Dixie PIT from a similar program at Kennesaw Mountain High School in Georgia.Not that it was easy.Chevalier's first problem to overcome was product-related.Should schools be selling coffee?What about sugar content?Kenton County Food Service Director Ginger Gray helped.She made sure all the drinks,which use non-fat milk,fell within nutrition guidelines.

When it comes to social behaviour,mammals are in a league of their own.Some birds may form pairs,or even cooperate to hunt,but the complexity of their relationships can hardly compare to those within a school of dolphins,a herd of elephants or a group of humans.What makes mammalian social groups different from a flock of starlings or a shoal of fish,is that in many cases the individuals could recognize each other.Although we may think that all elephants look pretty much the same,we can easily tell individuals of our own species apart and it has become clear through studies that the same is true of other species.Dolphins have their own signature whistles that act like "names",and elephants can recognize and greet other individuals they have known but not seen for many years.This is something that only a few species of birds appear to be able to do. Mammals in complex social groups not only recognize each other as individuals,but also they remember a lot of information about that individual.Social groups often rely on this memory--such as knowing who is dominant to whom,who is related to whom,and who has done what to whom in the past.It's like remembering who you have lent money to or done a favour for,and who hasn't repaid that money or has talked about you behind your back.You have to learn who to trust,who your friends are,and who to watch out for. All this remembering goes on in a particular part of the brain called the neocortex .If you compare the size of a mammal's social group with the size of this part of the brain,you will find they are remarkably closely related.This area seems to take a long time to develop fully and animals in which it is very large take a very long time to grow up to adulthood.During this time,the youngster has to learn all the rules of social behaviour in their group and to piece together all the relationships between the group members:Knowledge that will be needed to avoid getting into trouble. What is special about a mammalian social group according to the passage?

Running is becoming popular these days. Many of us run for health. Doctors say many health problems come from these bad habits: eating and drinking too much, smoking and not taking enough exercise. Doctors tell us. "Eat and drink less, don't smoke, and exercise more." Running is a good way of exercise because it helps to build a strong heart. It also helps most people lose weight. One 68-year-old woman runs three times a week. "I love to eat." She says. She runs to lose _ Running is good for health in other ways, too. Many runners say running keeps colds and other small health problems away. "Running is my doctor." says one man. Running can also help people to relax. So today men and women of all ages enjoy running. .The writer mainly tells us _ .

You want to know where the safest place for young children is in the car? For a child of any age, the back seat is the safest place and the safest part of the back seat is the middle. In the back seat, the child is farthest away from the force or effect of head-on collision , which can cause the most injuries. All fifty states of theprefix = st1 /USAhave laws requiring the use of safety seats for young children. If you have children under 8 years of age weighing no more than 80 pounds, it is necessary to fit your car with a special child safety seat. The child safety seat comes in three types or sizes: the first type is designed for babies from birth to one year of age, until the baby weighs about 20 pounds; the second size is for children between one and four years of age, who weigh between 20 and 40 pounds; the third kind is used by older children big enough to use the car's belt system. Moreover, all these safety seats must be fitted and held in place on the car's back seat. If your child does need your attention while you are driving, don't look back. Just pull over . In addition, always be sure your child is properly fastened throughout the entire trip. Children who can unfasten their own car seats are subject to fatal injuries in an accident. Start early in your child's life teaching them that car safety is serious business and make sure you give a good example and always wear your own seat belt. What safety tip is given in this passage?

That summer I drank every day, everywhere I went. I had a bottle in my drawer next to me and a bottle next to my bed. I never did another drug, but I drank so much that my family finally asked a priest for help. My father gave me a bottle of medicine for alcoholism that produces unpleasant symptoms when users drink alcohol. I drank while taking it, which made me very sick. And I still drank. When the priest came, he said, "Jimmy, doctors said that with your diseases and the amount of drinking you're doing, _ . So your choice is either to stop drinking and live or to continue drinking and die within six months." I said, "I know I can't stop, so guess I'll have to die." The priest told my family what I said. My little brother-who is like my soul mate, looked at me with tears in his eyes and said, "But we don't want you to die." All I could think of was how desperately I had to get out of that room at that moment and have a drink. But I finally stopped drinking. I was on the care team of my dentist Russell. A lot of people in New York knew him. At the time he was the most famous dentist in the city. He drank heavily and was also with AIDS, so I was selected to be on his care team. Everybody on the team was sober but me. He went through dementia and died so quickly before my eyes. I stopped drinking and I've been with the disease for 35 years now. How did the author stop drinking?

Is there a magic cutoff period when children become responsible for their own actions? Is there a wonderful moment when parents can become lookers-on in the lives of their children and shrug , "It's their life," and feel nothing? When I was in my twenties, I stood in a hospital passage waiting for doctors to put a few stitches in my son's head. I asked, "When do you stop worry?" The nurse said, "When they get out of the accident stage. " My mother just smiled gently and said nothing. When I was in my thirties, I sat on a little chair in a classroom and heard how one of my children talked continually and disturbed the class. As if to read my mind, a teacher said. "Don't worry, they all go through this stage and then you can sit back, relax and enjoy them" My mother just smiled gently and said nothing. When I was in my forties, I spent a lifetime waiting for the phone to ring, the cars to come home, the front door to open. A friend said, " They're trying to find themselves, Don't worry, in a few years, you can stop worrying. They'll be adults. " My mother just smiled gently and said nothing. By the time I was 50, I was sick and tired of being weak. I was still worrying over my children, but there was a new wrinkle, there was nothing I could do about it. My mother just smiled gently and said nothing. I continued to suffer from their failures, and be absorbed in their disappointments. My friends said that when my kids got married I could stop worrying and lead my own life. I wanted to believe that, but I was haunted by my mother's warm smile and her occasional "You look pale. Are you all right?" Call me minute you get home. Are you depressed about something ?" Can it be that parents are sentenced to a lifetime of worry? One of my children became quite anxious about me recently, saying, "Where were you ? I've been calling for three days, and no one answered. I was worried. " I smiled a warm smile . The torch has been passed. According to the passage, which concern will last forever?

Bats are unusual animals. Even though they fly, they are not birds.Bats are the only mammals that fly. A mammal is an animal that has hair and feeds its babies with its own milk.Mother bats have babies each spring. Baby bats hang onto their mothers until they learn to fly by themselves. Bats can be many different colors. Most are brown, but some are black, orange or even green. Even though many people do not like bats,bats don't usually cause people trouble. Only vampire bats are very dangerous. Bats in the United States help people.Every year they eat millions of bad insects! Bats sleep all day because they cannot see well in the bright sunlight. They hang upside down in dark places. As soon as darkness begins to fall,bats wake up.They fly around easily and quickly at night. Some bats fly at night,while others fly only in the evening or the early morning. Bats make sounds that help them fly,since they cannot see well. People cannot hear these sounds. When bats make sounds, the sounds hit objects in front of them and go back at them. Most bats eat mosquitoes and moths ,but there are some bats that will catch fish swimming in water and eat them.Still other kinds of bats eat birds or mice.Bats that live in very hot areas eat only some parts of flowers. Bats that live in cold areas sometimes sleep all winter.That means they _ . Other bats that live in cold areas fly to warmer places for the winter. What's the best title for the passage?

On Thursday October 3, Adam Harper decided to stop drinking coffee. Adam is a MBA student at Harvard University. He studies long hours, gets very little sleep and as a result, he drinks a lot of coffee---anywhere from five to six cups a day. Recently, Adam felt that drinking thus much coffee was making it hard for him to sleep at all. He also began having problems with his concentration , and complained of stomachaches. Adam's doctor made this suggestions: stop drinking coffee altogether. When Adam got up on October 3, he began his day without his morning coffee. By 11:00 a.m., Adam was in a terrible mood . He was tired and had a headache. At 11:30, he had a meeting with his student advisor. In the meeting, he found it almost impossible to continue. What was going on? Caffeine, a chemical found in coffee, was most likely the reason for how Adam felt. Caffeine is a stimulant that boosts energy levels and improves concentration- but only for a short time. Lowering caffeine consumption often causes a drop in blood pressure and the result is a "coffee headache", People who stop drinking coffee often say they feel tired and moody, and find it hard to focus. The good news is that these feeling usually pass after four and five days. During this time, doctors suggested taking some aspirin for the headache. So, if Adam can wait, in less than a week, he may be feeling much better. People may feel _ when they stop drinking coffee.

Scottish pupils recently were part of a new scheme that allowed them to take their exams online. Those examinations provided a glimpse of the future in May when 120 _ in 10 centers in Scotland sat in front of computers to take a multiple-choice online exam. Although candidates were using a computer mouse instead of a pen, in all other ways the exam was the same as normal. Exam rooms were set out to ensure that only the candidates and the teachers were able to see the individual screens. The online answers were sent directly to a safe area. According to the students at St Ninian's in East Renfrewshire who took an online French exam, it was definitely the most motivated they had ever felt when taking an exam. "I could go as fast as I wanted to, rather than as slow as everyone else wanted to," said one. "It was better than looking back and forth between the questions," said another. One pupil even described it as fun. Their head teacher, Dorothy Graham, was not so surprised, "They are so used to doing things on computers that it seems natural for them. The boys liked it because they didn't have to worry about how neat their work was." The only things that worried her were power cuts and systems' crashing. It's thought that online exams could be the norm in about five years. However, last year there were warnings about computerizing exams in England and Wales. It's thought that it could be unfair to some students if they come from homes without access to a computer. According to the head teacher, pupils won't be able to take the exam if _ .

When Babbage was working atprefix = st1 /Cambridge, a new idea occurred to him. He wanted to construct a calculating machine to work out the solutions to maths problems not only with correctness but also with a speed beyond the power of any human mind. His machine could solve problems involving long rows of figures in one continuous operation . In 1822 Babbage exhibited his invention and won a prize from the government. After that, he immediately started to work on a larger machine designed to solve more difficult problems. Although he received some money left by his father, the money was not enough to support his design. He wrote to the government about his plan and was givenPS2500 to start with, a sum worth much more in those days than it is now. Babbage continued his work inLondonfor four years. Then his health broke down, and he had to take a long holiday abroad. When he returned toLondonin 1828, he was at the end of his resources. Many bills remained unpaid. His chief assistant and co-workers quarreled with him and left with many expensive tools. For one year no work was done. During this period, Babbage, whose mind was always active, suddenly thought of a completely new idea for the machine. He rushed to meet the government officials to explain his new idea. But this time, they were unwilling to help him. For eight years, they refused to say whether they wanted the machine or not, and their final answer was "No." From 1828 to 1839, Babbage held the position of professor atCambridgevery successfully. But his greatest work was the unfinished calculating machine which stood covered in dust in his house. It was the beginning of the modern computer. The machine Babbage designed would solve difficult maths problems _ .

Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible ? For one thing, it's everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking. Make friends with dainty eaters. Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in. See happy movies... and always get the smaller bag of popcorn . According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container. Eat breakfast. Nutritionists have gone back and forth about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising. Divide your food and conquer overeating. Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you're eating and of portion size. Researchers advise reallocating snack foods into small plastic bags. It sounds simplistic, but it works. Which of the following is TRUE according to the passage?

"If people are watching a tragedy, they eat up to 29% more popcorn.",
"People are likely to eat more food when staying with friends.",

Some people don't mind being fat. Other people can keep slim without any effort. But a lot of people do put on too much weight and don't like it. The question is, what can they do about it? Some believe exercise can be helpful. But the trouble is that it only makes you want to eat more. You might sweat out a couple of pounds playing tennis or climbing a mountain, but you put it all back on again with a big steak or bread and jam. A helpful way is food choosing. But what sort of food should you choose? Some believe that the less they eat, the slimmer they will be. They don't eat anything until they become weak with hunger. Some stick to milk and bananas. You'll find you need a lot of bananas, and unless you live where they grow, they aren't cheap. Others say that if you eat things like hard-boiled eggs, and apples with their skins on which are hard for your stomach to digest, the more you eat, the thinner you get. This is because you use up the fat in your body to get the energy to digest the food. For most of us these methods are too extreme. The simplest way is just to cut down on the carbohydrates that means not eating bread, potatoes, cakes, sugar, rice, and so on and eating anything else you like. It's straight forward and often quite effective. The practical method suggested here is _ .

An increase in students applying to study economics at university is being attributed to the global economic crisis awakening a public thirst for knowledge about how the financial system works. Applications for degree courses beginning this autumn were up by 15% this January, according to UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society said applications to do economics at A-level were also up. Professor John Beath, the president of the society and a leading lecture at St Andrews University, said his first-year lectures which are open to students from all departments--were drawing crowds of 400, rather than the usual 250. "There are a large number of students who are not economics majors, who would like to learn something about it. One of the things I have done this year is to relate my teaching to contemporary events in a way that one hasn't traditionally done. " He added. University applications rose 70% last year. But there were rises above average in several subjects. Nursing saw a 15% jump, with people's renewed interest in careers in the pubic sector , which are seen as more secure in economic crisis. A recent study showed almost two thirds of parents believed schools should do more to teach pupils about financial matters, and almost half said their children had asked them what was going on, although a minority of parents felt they did not understand it themselves well enough to explain. Zack Hocking, the head of Child Trust Funds, said: "It's possible that one good thing to arise from the downturn will be a generation that's financially wiser and betterequipped(...) to manage their money through times of economic uncertainty."

College life can become a great struggle because students have to balance school, a social life, and sometimes a job as well. The following steps could help the grades of college students. Go to class. Why did your parents pay for your tuition or why are your parents paying their taxes for financial aid? Even when you don't feel like attending class, just go. 71 Many classes have in-class assignments, pop quizzes, and case studies that only could be taken in class. If you are not there, you might lose points. Some students start better than they finish. They do that in order to give themselves room to slack near the end of the semester, which can be a mistake. Push yourself to do your best on every assignment. Stay on top of your game and don't lose focus.

What looks like a black hole, behaves like a black hole, but is bigger than a black hole? Two black holes! Astronomers last week discovered a pair of enormous black holes far out in the galaxy that appear to be dancing toward each other. However, astronomers say the collision is not likely to occur for several million years. Black holes are objects in outer space that are so dense that nothing can escape their gravity. They often sit in the center of a galaxy -- like the Milky Way --and suck up everything near them. The gravitational pull of a black hole is so intense that not even light (Which travels faster than anything else in space) can make it past without being swallowed. Black holes, like the one at the center of the Milky Way, are enormous. Scientists call some of them "supermassive", because they can be a few million times the size of most stars. Their size, their mass, and their inescapable gravity make black holes a giant force of nature in outer space. Because there is no light near black holes, astronomers cannot actually see them; they are completely invisible to us on the Earth. Scientists manage to detect the existence of a black hole by watching what happens to other objects, or matter floating in space. So how did scientists manage to get a good look at a region so faraway? The team used an orbiting NASA observatory known as Chandra. This special observatory uses X-rays rather than light to watch far out into space. Right before a star gets sucked into a black hole, it produces a large number of X-rays. Which of the following statements CANNOT be used to describe a black hole?

My passage into eighties a few weeks ago gave me a moment's reflection and the thought that I should watch how others in this situation have been affected. After a while it seemed to me that the first 80 years are the hardest. Once you reach 80, everyone wants to carry your baggage and help you up steps. If you forget your name or anybody else's name, or an appointment or your own telephone number, or promise to be three places at the same time, or you can't remember how many grandchildren you have, you need only explain that you are 80. Being 80 is a lot better than being 70. At 70 people are mad at you for everything. At 80, you have a perfect excuse no matter what you do. If you act foolishly, it's your second childhood. Everybody is looking for symptoms of your failure of the brain. Being 70 is not fun at all. At that age they expect you to retire to a house in Florida and complain about your arthritis and you ask everybody to stop mumbling because you can' understand them. (Actually your hearing is about 50% gone.) If you survive until you are 80, everybody is surprised that you are still alive. They treat you with respect just for having lived so long. Actually they seem surprised that you can walk and talk sensibly. So please, folks, try to make it to 80. It's the best time of life. People forgive you for anything. In response to the question of what years were the most difficult, an 80-year-old responded "those between 10 and 70". What problems do the 80-year-olds often have?

Do you still remember the funny question: why did the chicken cross the road? To get to the other side. Most people know this joke. But recently, some people have been much more concerned with how the grizzly bear and mountain lion can cross the road. Millions of animals die each year on US roads, the Federal Highway Administration reports. In fact, only about 80 ocelots , an endangered wild cat exist in the US today. The main reason? Road kill. "Ecopassages" may help animals cross the road without being hit by cars. They are paths both over and under roads. "These ecopassages can be extremely useful, so that wildlife can avoid human conflicts," said Jodi Hilty of the Wildlife Conservation Society. But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed that the lion used the passage. Builders of some ecopassages try to make them look like a natural part of an area by planting trees on and around them. Animals seem _ . Animals as different as salamanders and grizzly bears are using the bridges and underpasses. The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an animal overpass! The writer uses the example of "ocelots" to show that _ .

I used to think Dad didn't love me at all, because he never tried to hug or kiss me. But whenever I felt sad or lonely, Dad was always there. When I was in high school, Dad retired and set up a food _ on the street near my school. Every day when I finished school, my classmates and I would pass his food stand. But I really hated talking to Dad, because I did not want my classmates to know my dad was selling noodles on the street! One night, I couldn't stand it any more and shouted, "Dad, could you stop selling your stupid noodles? I don't need a father who sells noodles on the street!" At that moment, Dad was shocked. He tried to say something but didn't. His eyes were filled with tears and sadness. It was the first time for me to see Dad crying. My mum later told me Dad was selling noodles to save money for my college education. Even today I still feel guilty for that night. Time really flies. I finished college and then left my home city.

How many times a day do you check your email? When you wake up? Before bed? A dozen times in between? The technology that was supposed to simplify our lives has become the vital time-suck: the average teen spends more than seven hours a day using technological devices, plus an additional hour just text-messaging friends. The advantage of technological devices is connectedness: email lets us respond on the go, and we are in touch with more people during more hours of the day than at any other time in history. But is it possible we're more lonely than ever, too? That's what MIT professor Sherry Turkle observes in her new book, Alone Together, a fascinating portrait of our changing relationship with technology. Turkle details the ways technology has redefined our comprehension of closeness and loneliness--and warns us of the danger of accepting such virtual relationships in place of lasting emotional connections. For Turkle, the biggest worry is the effect all these shallow connections have on our development. Is technology offering us the lives we want to live? "We're texting people at a distance," says Turkle, "We're using lifeless objects to convince ourselves that even when we're alone, we feel together. And then when we're with each other, we put ourselves in situations where we are alone--constantly on our mobile devices. It's what I call a perfect storm of confusion about what's important in our human connections." What can't be denied is that technology, whatever its faults, makes life a whole lot easier. It allows us to communicate with more people in less time and makes conversation simple. But it can also be seductive , providing more stimulation than our natural lives. There are usually some unhealthy videos online which remove teenagers' attention from their schoolwork. Besides, some online activities make people addicted, which occupied their daily life and affected their ability to form real-world relationships."Technology can be more immediately satisfying than the labor of building an intimate relationship," said one highschool student, "Every time I text, I start to have some happy feelings." But are any of those feelings equal to the kind we feel when engaged in real, face-to-face communication? Online, you can neglect others' feelings. In a text message, you can avoid eye contact. A number of studies have found that this generation of teens is less sympathetic than ever. That doesn't spell disaster, says Turkle--but, What worries Turkle most is that more and more people are _ .

How did the ancient Chinese keep food warm in winter? Facilities like electric rice cookers, microwaves, and electric kettles, make it easy for people to keep food warm and enjoy a comfortable winter. So how did Chinese people in ancient times keep food warm in winter without these? In fact, ancient Chinese people used their own methods of heat preservation as early as the Shang and Zhou dynasties. * "Wen Ding", ancient rice cooker One of the major functions of an electric rice cooker is to keep food warm. The "Wen Ding", an ancient cooking container, served the same purpose, but instead of using electric energy, the ancient cooking container, served the same purpose, but instead of using electric energy, the ancient cooking container preserved heart by burning fuels like charcoal. The "Wen Ding" unearthed in Nanjing in 1989 is thought to be the oldest of its kind discovered in China, dating back to the Stone Age, The craftsmanship of making the "Wen Ding" was developed in the Bronze Age. The bronze Ding from Shang and Zhou dynasties took on different shapes and structures. * "Ran LU", ancient small hot pot The "Ran LU" is a small size cooking vessel made of bronze, which can be divided into three parts. A charcoal stove forms the main structure, with a bottom tray to hold charcoal ashes, and a movable cup at the top. Some experts have concluded that the vessel's structure suggests it may have been used as a small hot pot and that these vessels became popular in the Warring States Period(475--221 BC) *Bronze You, ancient kettle The Bronze You was one of the most common wine containers during the Shang and Zhou dynasties. The Bronze You can also be used to warm wine. For example, the Bronze You with beast mask design, unearthed in Jiangxi province, has an opening where charcoals could be placed. Just as people today can't do without an electric kettle, the Bronze You allowed people to enjoy a hot drink. *Bronze Yan, ancient steamer Although the "Wen Ding" was effective at keeping food warm, the ancient Chinese people later found that its burning produced pollution. As a result, the Bronze Yan was made with a two-tier structure and used to steam rice and other grains. After the Eastern Han Dynasty (AD 25-AD 220), further improvements to the Bronze Yan led to the modern-day steamer. When did the "Ran LU" become popular?

Scientists have proved that sleeping and learning go hand in hand. Even a short nap can boost our memory and sharpen our thinking. But the relationship goes deeper than that. "The brain is not passive while you sleep," scientist Anat Arzi said. "It's quite active. You can do many things while you are asleep." Arzi and her coworkers didn't try to teach the sleeping volunteers any complex information, like new words or facts. Instead, the scientists taught volunteers to make new connections between smells and sounds. When we smell something good, like a flower, we take deep breaths. When we smell something bad, we take short breaths. Arzi and her co-workers based their experiment on these reactions. Once the volunteers fell asleep in the lab, the scientists went to work. They gave them a whiff of something pleasant and meanwhile played a particular musical note. They didn't wake up, but they heard--and sniffed deeply. Then the scientists gave the volunteers a whiff of something terrible and played a different musical note. Again, the volunteers heard and smelled--a short snort this time--but didn't wake up. The researchers repeated the experiment. After just four repetitions, volunteers made a connection between the musical notes and their paired smells. When the scientists played the musical tone that went with good smells, the sleepers breathed deeply. And when the scientists played the musical tone that went with bad smells, the sleepers breathed briefly--despite there being no bad smell. The next day, the volunteers woke up with the sound-smell connection. They breathed deeply when hearing one tone and cut their breaths short when hearing the other, which must have been unusual for them. Imagine walking down the street and taking a deep breath upon hearing a particular sound! When the volunteers woke up the next day, they _ .

It was a simple letter asking for a place to study at Scotland's oldest university which helped start a revolution in higher education. A 140-year-old letter written by a lady calling for her to be allowed to study medicine at St Andrews University has been discovered by researchers. Written by Sophia Jex-Blake in 1873, the seven-page document, which urged the university to allow women to study medicine at the institution, was released yesterday on International Women's Day. The document was discovered buried in the university archives by part-time history student Lis Smith, who is completing her PhD at St Andrews Institute of Scottish Historical Research. She said: "We knew that Sophia Jex-Blake and her supporters, in their effort to open up university medical education for women, had written to the Senatus Academicus at St Andrews in an attempt to gain permission to attend classes there, but we didn't know documentary evidence existed. While searching the archives for information about the university's higher certificate for women, I was astonished to come across what must be the very letter Jex-Blake wrote." In the letter, Sophia and her supporters offered to hire teachers or build suitable buildings for a medical school and to arrange for lectures to be delivered in the subjects not already covered at St Andrews. Although her letter was not successful, it eventually led to the establishment of the Ladies Literate in Arts at St Andrews, a distance-learning degree for women. The qualification, which ran from 1877 until the 1930s, gave women access to university education in the days before they were admitted as students. It was so popular that it survived long after women were admitted as full students to St Andrews in 1892. Ms Jex-Blake went on to help establish the London School of Medicine for Women in 1874. She was accepted by the University of Berne, where she was awarded a medical degree in January 1877. Eventually, she moved back to Edinburgh and opened her own practice. Lis Smith found Sophia's letter to St Andrews University _ .

It's impolite to spit out the first bite of your dinner. But to a type of Australian snake, this rude behavior is a matter of life and death. The snake, called a floodplain death adder , eats two types of frogs that are hard to stomach. The frogs produce chemicals to defend them from predators . One of these species, the Dahl's frog, can kill a snake that tries to eat it. The other species, the marbled frog, is less dangerous but still tough to eat. When attacked, _ produces a glue like substance. Leaves and branches get caught up in this material, making a big sticky mess that gets in the way of anything trying to swallow it. A marbled frog can even get stuck on the head of an attacking snake. Both frogs have good defense methods. But the floodplain death adder knows how to get around each of them. Floodplain death adders quickly strike these frogs, using their poisonous teeth to inject poison. But then, instead of swallowing their dinner immediately, the snakes sit back and wait for their preys to become safe to eat. That's because both the Dahl's frog's protective toxin and the marbled frog's glue break down over time. After a while, the frog toxin is no longer poisonous and the glue is no longer sticky. The two substances break down at different rates, and floodplain death adders seem to know the difference, And adder waits for a different length of time depending on the species of frog it just struck. The stickiness of the marbled frog glue decreased by as much as two-thirds after just 10 minutes. And that's just about how long an adder waits before eating a marbled frog. On the other hand, the snakes wait for about 40 minutes before eating a Dahl's frog. That's enough time for the frog's toxin to break down into harmless substances. But even a quick strike gives a taste of the Dahl frog's toxin. After striking such a frog, a floodplain death adder thrashes around and lies on its back with its mouth open, It's like the snake has just had a mouthful of chili pepper. By comparison, when given frogs that have no chemical defenses, floodplain death adders eat their prey immediately after striking. Snakes, despite the fact that they've got this tiny pea-size brain are clearly capable of recognizing what kind of frog they've bitten. What's the best title of the passage?

Scientists have devised a way to determine roughly where a person has lived using a strand ( ) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S. diet is ly identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes ( ). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional difference. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad region roughly corresponding to the movement of rain systems. "It's not good for pinpointing ( )," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researches. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming. "It's still a substantial area," Park said, "But it narrows its way down for me." What is the scientists' new discovery?

Sixteen years ago, Eileen Doyle's husband, an engineer, took his four children up for an early morning cup of tea, packed a small case and was never seen or heard from again. Eileen was astonished and in a state of despair. They had been a happy family and, as far as she knew, there had been nothing wrong with their marriage. Every day of the year a small group of men and women quietly pack a few belongings and, without so much as a note or a good-bye, close the front door for the last time, leaving their debts, their worries and their confused families behind them. Last year, more than 1,200 men and nearly as many women were reported missing from home -- the highest in 15 years. Many did return home within a year, but others rejected the past completely and are now living a new life somewhere under a different identity. To those left behind this form of desertion is a terrible blow to their pride and self-confidence. Even the finality of death might be preferable. At least it does not imply rejection or failure. Worse than that, people can be left with an unfinished marriage, not knowing whether they will have to wait seven years before they are free to start a fresh life. Clinical psychologist Paul Brown believes most departures of this kind to be well planned rather than impulsive. "It's typical of the kind of personality which seems able to ignore other people's pain and difficulties. Running away, like killing yourself, is a highly aggressive act. By creating an absence the people left behind feel guilty, upset and empty." What's the author's attitude towards the departures of this kind?

"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. Ibrahim Koroma values his certificate because it _ .
