Sushi is a kind of food made with a mixture of cooked or raw fish, vegetables, and rice. Although Sushi is most commonly considered to have its origin in Japan, it actually began in China during the 7thCentury. At that time, any fish caught had to be preserved. Raw fish was cleaned and then pressed between layers of heavy salt. After a couple of months, the whole process was complete. Over time, a discovery was made that by rolling the fish in rice that had been soaked in vinegar the fish was easily fermented in a few days rather than months. The rice was then thrown away and the fish was eaten. However, with a food shortage, people began consuming the rice as well as the fish and thus, Sushi today as we know was born. However, in the 1800s, a famous chef by the name of Yohei created two styles of Sushi--one called Edo, and the second, Osaka, for two cities. Sushi is usually consumed with hot green tea. Also, Gari is offered free and eaten between bites to create a better taste. Two kinds of sauce are usually available: one is soy sauce, which is poured on most kinds of Sushi; the other is a thick sweet sauce used on eel . Sushi has taken the world by storm and today is a multi-billion dollar industry. Its popularity continues to rise because people are looking for healthy food that is quick and easy to make. With such unbelievable popularity as well as the health benefits of eating Sushi, it is likely that this food will continue to be a part of everyday life for many more centuries to come.

From Mr. Ward Hoffman. Sir, I was halfway through Professor Raj Persaud's article "What's the tipping point?" (Financial Times Weekend, April 9-l0) when it occurred to me that what I was reading was not ironic . If Prof Persaud wants to know why Americans tip in restaurants, he need only ask the first American he meets inprefix = st1 /London. Americans tip in restaurants for one reason, and one reason only: we tip to supplement the salary of restaurant workers. Quality of service does not enter into it, beyond the fact that one may tip a bit less for poor service, or a little more for good service. Not tipping at all in a non-fast-food restaurant is not a choice. In the US, one used to tip about 15 per cent for dining in a family-style restaurant or in an up-market restaurant. Here, in San FranciscoBayarea restaurants, we are encouraged to tip 20 per cent or more, to help restart workers live in this very expensive area. After eating at an Italian restart in my city, I left a tip of 20 per cent on the non-tax part of our dinner bill. It was expected. There is nothing more complicated than that about Americastipping in restaurants. Ward Hoffman, Palo Alto, CA94306,US * * * From Mr. Philip McBride Johnson. Sir, I agree with most of Raj Persaud's opinion about the doubtful value of tipping, but with one exception. Tips can be very useful when one is a repeat customer or diner. It is only when the tipper is a stranger and likely to remain so that the system does not work to his or her advantage. But frequent a hotel or a restaurant, always tip a bit more, and the difference in service and treatment will be easily felt.

Diana Jacobs thought her family had a workable plan to pay for college for her 21-year-old twin sons: a combination of savings, income, scholarships, and a modest amount of borrowing. Then her husband lost his job, and the plan fell apart. "I have two kids in college, and I want to say 'come home', but at the same time I want to provide them with a good education." says Jacobs. The Jacobs family did work out a solution. They asked and received more aid from the schools, and each son increased his borrowing to the maximum amount through the federal loan program. They will each graduate with $20,000 of debt, but at least they will be able to finish school. With unemployment rising, financial aid administrators expect to hear more families like the Jacobs. More students are applying for aid, and more families expect to need student loans. College administrators are concerned that they will not have enough aid money to go around. At the same time, tuition continues to rise. A report from the National Center for Public Policy and Higher Education found that college tuition and fees increased 439% from 1982 to 2007, while average family income rose just 147%. Student borrowing has more than doubled in the last decade. "If we go on this way for another 25 years, we won't have an affordable system of higher education," says Patrick M. Callan, president of the center. "The middle class families have been financing it through debt. They will send kids to college whatever it takes, even if that means a huge amount of debt." Financial aid administrators have been having a hard time as many companies decide that student loans are not profitable enough and have stopped making them. The good news, however, is that federal loans account for about three quarters of student borrowing, and the government says that money will flow uninterrupted. How did the Jacobs manage to solve their problem?

Jenny, I often think if I am as important to you as you are to me. We had an unhappy time yesterday. I really felt sad after it and almost apologized to you. However,you could still laugh and talk with others like nothing had happened. I suddenly realized that I was not that important to you. You didn't even realize that I was angry and sad. What's more,you even forgot my birthday this year. Goodbye,my friend. I have closed my feeling toward you. It is sad to say goodbye,my friend. But it is meaningless for us to be friends any longer. Lucy Dear Lucy, I'm sorry that I hurt you so much yesterday. But here is something I really need to tell you. I never thought the quarrel we had yesterday was as serious as you thought. I just felt tired and didn't feel like going shopping. Susan and Lily are also my good friends. I couldn't pretend not seeing them when they passed by. I also couldn't let them know I was blue because of the quarrel. I didn't want them to feel sad just because I was sad. I'm your best friend,but I don't want to be your only friend. I don't want to be with you all the time because sometimes I need to have my own time. I want to spend some time with my other friends and my brother. Please try to make more friends. You will feel much happier if you have more friends. And remember,I'm your best friend forever! Jenny What's the purpose of Lucy's letter?

Whether the eyes are "the windows of the soul" is debatable;that they are intensely important in interpersonal communication is a fact.During the first two months of a baby's life,the stimulus that produces a smile is a pair of eyes.The eyes need not be real:a mask with two dots will produce a smile.Significantly,a real human face with eyes covered will not motivate a smile,nor will the sight of only one eye when the face is presented in profile .This attraction to eyes as opposed to the nose or mouth continues as the baby matures.In one study,when American four--year--olds were asked to draw people,75 percent of them drew people with mouths,but 99 percent of them drew people with eyes. In Japan.however,where babies are carried on their mother's back,they do not acquire as much attachment to eyes as they do in other cultures.As a result,Japanese adults make little use of the face either to encode (...) or decode meaning.In fact,Argyle reveals that the "proper place to focus one's gaze during a conversation in Japan is on the neck of one's conversation partner." The role of eye contact in a conversational exchange between two Americans is well defined:speakers make contact with the eyes of their listener for about one second,then dance away as they talk;in a few moments they re-establish eye contact with the listener or reassure themselves that their audience is still attentive,then shift their gaze away once more.Listeners,meanwhile,keep their eyes on the face of the speaker,allowing themselves to glance away only briefly.It is important that they be looking at the speaker at the precise moment when the speaker reestablishes eye contact:if they are not looking,the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will stop the conversation.Just how critical this eye contacting is to the maintenance of conversational flow becomes clear when two speakers are wearing dark glasses:there may be a sort of traffic jam of words caused by interruption,false starts,and unpredictable pauses. According to the passage,a conversation between two Americans may break down due to _ .

It was June 15, and in two days I would be turning thirty. I was not sure about entering a new decade of my life and feared that my best years were now behind me. My daily routine included going to the gym for a workout( ) before going to work. Every morning I would see my friend Nicholas at the gym. He was seventy nine years old and in terrific shape. As I greeted Nicholas on that particular day, he noticed I wasn't full of my usual vitality and asked if there was anything wrong. I told him I was feeling anxious about turning thirty. I wondered how I would look back on( )my life once I reached Nicholas's age, so I asked him, "What was the best time of your life?" Without hesitation, Nicholas replied, "Well, Joe, this is my philosophical answer to your philosophical question: When I was a child in Austria and everything was taken care of for me and I was _ by my parents, that was the best time of my life. When I was going to school and learning the things I know today, that was the best time of my life. When I got my first job and had responsibilities and got paid for my efforts, that was the best time of my life. When I met my wife and fell in love, that was the best time of my life. The Second World War came, and my wife and I had to flee Austria to save our lives. When we were together and safe on a ship bound for North America, that was the best time of my life. When we came to Canada and started a family, that was the best time of my life. When I was a young father, watching my children grow up, that was the best time of my life." "And now, Joe, I am seventy nine years old. I have my health, I feel good and I am in love with my wife just as I was when we first met. This is the best time of my life." Why was the writer anxious?

Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning . Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms. Certain microorganisms cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release poisons that make people sick. Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops. Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms. When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous. Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied. Food poisoning can be caused by all the following EXCEPT _ .

Of all the websites, one that has attracted attention recently is myspace.com. Most of this attention has come from the media and tells every reason why the website should be shut down. The danger of internet predators is indeed a tough reality, but shutting down the site is not the answer. If myspace.com were shut down, another site would quickly take its place. Therefore, the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them. The key to staying safe on the Internet is to make sure that your profile is secure. The simplest way is to change the privacy setting on your profile to "private", which protects your information so that only the people on your friend list can view it. Although this is effective, it is not perfect. Predators can find ways to view your profile if they really want to, whether through hacking in or figuring out their way onto your friend list. Thus, you should never post too much personal information. Some people actually post their home and school addresses, date of birth, and other personal information, often letting predators know exactly where they will be and when. The safest information is your first name and province. Anything more is basically inviting a predator into your life. Another big problem is photos. I suggest completely skipping photos and never posting a photo of a friend online without asking permission. Most importantly, never, under any circumstances, agree to a real-life meeting with anyone you meet online. No matter how well you think you know this person, there are no guarantees that they have told the truth. But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are. Hopefully, the next time you edit your profile, you'll be more informed about the dangers of Internet predators and take the steps to defend yourself. Lastly, do not send money to anyone you meet online. A common _ among Internet criminals is to request to pay for "expensive Internet charges" or "unreasonable Internet cafe fees". While it is indeed true that many countries in Eastern Europe, Asia, Africa and South America do not yet have Internet service readily available in all cities and towns, a sincere friend from one of these countries will be more than happy to pay their own Internet charges. Never, under any circumstances, should you send money to a stranger from another country(or within your own country for that matter) who claims monetary assistance is required to continue their contact with you. Kids can avoid web predators successfully by _ .

Housing Price in China has always aroused heated discussion among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8, 000 yuan per square metre, while in China, it is even higher than that in the United States. "This shows that there are some bubbles in Chinese real estate market," the International Finance News reported. Although the average price of residential houses in the United States, after changed to RMB, is about 8, 000 yuan per square metre, the houses in the US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If the US property developers sell their houses according to the building area, then the housing price will be even lower than 8, 000 yuan per square metre. In most big Chinese cities, such as Beijing, Shanghai and Shenzhen, houses are sold at a price even higher than those in the US. The high housing price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses cannot be compared with houses in the US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people's average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in the US? At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. Meanwhile, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered and Chinese public can really benefit from the economic achievement. It can be learned from the passage that _ .

"housing price in China will drop considerably very soon",
"a set of laws have been passed to improve Chinese real estate market",
"regardless of housing price, Chinese houses have poorer building quality than those in the US",

Range At present,there are five network firms---China Telecom,China Unicom,Jitong Communications,China Netcom and China Mobile---that are allowed to operate IP services in China.Each company has its advantages in service. Charge As the Ministry of Information Industry co-ordinates,the charges of IP calls of the five companies are the same,0.30 yuan per minute for DDD calls.4.80 yuan per minute for IDD calls,2.50 yuan for calls from the mainland to Hong Kong,Macao,and Taiwan,and 1.50 yuan from Shenzhen to HK,Zhongshan and Zhuhai to Macao.IP callers don't enjoy discounts on holidays. China Telecom has the widest coverage.All cities in China with telephone access and most countries in the world are open to China Telecom's IP card. China Unicom's IP card can reach 29 cities nationwide and more than 130 countries and regions worldwide.Jitong IP can access 12 cities in China and over 70 countries and regions worldwide. China Netcom's IP card can reach 14 cities in China and 149 countries and regions in the world. China Mobile's IP card is open to only six cities nationwide but can access more than 200 countries and regions worldwide. Voice quality China Telecom realizes its IP service by the public Intermet,therefore net congestion and voice delay may sometimes disturb conversations.The other four companies have their private data networks,which help to increase transmission speeds and improve voice quality. Other services China Telecom,Jitong and China Mobile offer account transfer services.Users can transfer the remaining sum of money on one card to another card. Jitong and Netcom Link their services with bank cards.One can enjoy IP's service without an IP card.Bank card users can make IP phone calls with their bank card numbers,so they needn't buy new IP cards and remember the new numbers again and again. As for customer service,China Telecom,China Unicom and China Mobile provide free hot line service,while Jitong and Netcom charge for their services. If we want to access more foreign countries and regions with better voice quality,we'd better choose_IP card.

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

A new product - the Apple Watch - into the market. Last year, the watch was firstly introduced by Tim Cook, Apple's CEO. The price of the watch is from $349 to $1,099, depending on its size and whether it is a sports or regular one. Apple engineers and designers have put in a lot of thought and hard work into creating this "small screen" on your wrist . The "sensor " on the screen not only finds your finger, but also knows the difference between when you are tapping , and when you are pressing hard er. The watch also has "haptic feedback ". You can s end personal messages to your friend --such as drawing a star or a special sign with your fingers, or tapping the watch, say 3 times, and your friend will receive those taps on their wrist. Besides telling the time, the watch will use 'Bluetooth' to connect with your iPhone and show calls or text messages that come in. According to Tim Cook, the watch may open up a whole new area of applications that we had never thought of. Some car f actories like BMW have developed an app that allows its car owners to open their cars with the watch. A 'Hotels' app may allow you to open the door to your hotel room without worrying about losing the smart-card. And finally, even at the airport--passengers may be able to simply wave their wrist to check into their flight. The biggest use of the watch, however, is as your personal fitness coach. The watch can show your pulse (heartbeat) using a sensor at the bottom of the watch. It also has the same sensor as your iPhone, so it knows when you are moving, and also how much you are walking or running. It will remind you if you have been sitting for too long without taking exercise. With apple watch, you can _ .

It's a nightmare for Huazhong University of Science and Technology (HUST): within a week, two students committed suicide by jumping off dorm buildings. Officials from the university are reluctant to give interviews. "We had a hard time calming down students who were shocked at the suicides," said Zhang Jingyuan, head of HUST's center for research and guidance for students' development. "Media coverage may arouse some students' negative emotions again. Suicide can be contagious ," Zhang said. The university reacted promptly to the first suicide on October 23. Advisors and class leaders conducted dorm-to-dorm checks to find students suffering depression. Then psychologists offered one-on-one counseling to them. Notice boards publicizing tips for identifying peers' mental problems and offering help were set up in front of dorm buildings. Leaflets carrying similar information were handed out to each dorm. However, the second suicide came seven days later. Both students were described as men of few words. Their schoolmates didn't see anything to indicate suicide. Zhang revealed that the two students had been bothered by mental disorders. But the school didn't know this until the students' close friends outside school and their parents unveiled the truth after the suicides. According to Zhang, there are only three full-time counselors working in the university's counseling center for its 60,000 students. He complained: "It's unrealistic to rely only on counselors to detect students' mental problems." Some universities in the US may be able to offer solutions to Zhang's worries. They have established programs to train students to be the bridge between troubled friends and counselors. At Worcester Polytechnic Institute, at Worcester, Massachusetts, US, young people in the Student Support Network role play to learn how to detect SOS signals from their schoolmates. They also practice how to gently persuade emotionally troubled students to go for professional help. To develop such empathy , many universities in China have organized campus events to popularize knowledge about mental health. But these are not that attractive to students. Ke Juanjuan, 24, is pursuing a master's degree in English translation at HUST. Ke has found that few of her peers will pay attention to activities about mental health when they are not troubled by it. Rather than bombard students with the words "mental health", Ke suggested the school organize lectures and workshops concerning study, job-hunting and relationships. She explained: "Students care about these topics. They tend to have problems in these areas and may thus get stuck in depression. "By helping students better deal with these problems, the school can effectively prevent self-inflicted injury and suicide among students." Effective prevention comes from long-term education for life instead of temporary intervention to meet an emergency, said Hu Yi'an. Hu delivers a course of lectures on life and death at Guangzhou University. He worries that universities have paid little attention to education for life. "Education for life helps students respect and love life so they won't resort to ending their lives when they have difficulties," said Hu. According to Hu, the principles can be incorporated into everyday teaching. In which column of a newspaper would you most probably read this passage?

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. When engineers develop the skycars, they have to deal with the following difficulties except _ .

One day,when 12-year-old Sean Redden went to a popular chat room on the Internet, he saw the name of someone he'd never seen there before, Susan Hicks. Her message was " Would someone help me? I can't breathe. Help me! I can't feel my left side." At first, Sean thought it was a bad joke and he told his mother Sharon Redden. But she asked, " It's not just some game, is it? The message was not a joke. " Susan Hicks" was actually 20-year-old Taija Laitinen, a student working late at night at a college library near Helsinki, Finland---almost 7,000 miles away from Sean's home in Texas. While searching the Internet, she began to feel terrible pain all through her body. The library was empty and the nearest phone was outside in the hallway. She couldn't move that far because any movement caused the pain to get worse. Then as the pain became worse, she began typing her message for help in the chat room. "I don't think it's a joke, mom," Sean said. He typed, " Where are you? The letters appeared, "Finland." Sean and Sharon couldn't believe it. Not knowing what else to do, Sharon called the local police and explained the situation to officer Amy Schmidt. Schmidt told Sharon to try to get the sick girl's phone number and address. Meanwhile, the Texas police called the international telephone operator and asked to be connected to the proper agency in Finland. The Texas police explained the situation and gave Susan's address to the Finnish operator. When Sean heard that, he typed, "Help is on the way." In the few minutes, the library door opened. Doctors and three policemen ran in. Taija turned once more to the computer, " They are here. Thanks. Bye-bye." At first when receiving the message for help, Sean _ .

Travel is fun and exciting, but it's not if you get sick. You may think, "Not me, I won't get sick in my holiday." But, for many people, that is what happens. Of course you don't want to spend your holiday sick in bed. So what can you do to stay in good health? There are three things you should remember when you travel: relax, sleep, and eat well. A holiday must be a time for relaxing. But very often it is not. Think about what you do when you are a traveller. There are many places to visit: museums, shops, parks, churches. You may spend most days walking around these places. This can be very tiring. You may have a terrible headache after a few hours. If this is the way you feel, you should take a rest. Don't ask your body to do too much. A tired body means a weak body. And a weak body gets sick easily. So sit down for a few hours in a nice place. In good weather, look for a quiet park bench . Or you can stop at a cafe. You can learn a lot by watching people while you rest. Sleep is also important. If you want to stay healthy, you need to get enough sleep. You may have trouble sleeping at night when you travel. There may be too many noises in your hotel or the bed may be uncomfortable. If this is true, don't be afraid to change rooms or hotels. Or you may get enough sleep for another reason. You may want to stay out late at night. In many cities, the nightlife can be very exciting. Then you should plan to sleep for an hour during the day. The extra hour can make a big difference. Finally, if you want to stay healthy, you must eat the right kinds of foods but you need to be careful about how much you eat. Lots of food is not good for you. So, remember this, if you want to enjoy your holiday, take care of yourself. Give your body some rest. Get enough sleep and eat good, healthy food. You can change your rooms or hotels, if _ .

Do you have a lucky number? What is it? Many people have a special number that they hope will bring them good luck. In Chinese culture, some numbers are believed to be lucky or unlucky based on the Chinese word that the number sounds similar to. For example, the word for the number 8 sounds similar to the word for "making a fortune ". So, people consider it a very lucky number. Some people will even spend a lot of money to have 8s in their phone numbers or vehicle license plate numbers. The opening ceremony of the Beijing Olympics began at 8:08 p.m. on August 8, 2008. The number 9 is also a lucky number because of its connection to the emperors of China. There were nine dragons on emperors' robes and Chinese myth held that the dragon has nine children. The number 9 also stands for "long lasting". That's why a man always proposes to(---)a woman with 99 or 999 roses. So what's a "bad luck" number in China? It might be 4. Many Chinese people see 4 as a "bad luck" number because it sounds similar to the character for "death". Because of this, many buildings skip the fourth floor, and simply call it the fifth floor. In Hong Kong, some buildings even skip all floors numbered with 4, such as, 4, 14, 24, 34 and all 40-49 floors. Some buildings also skip the 13th floor, as this is considered an unlucky number in many Christian countries. As a result, a building whose highest floor is 50 may have only 35 physical floors. Chinese people regard the number 9 as _ ?

"I'm seventy years old," says the gray-haired lady proudly to the entertainer at her Community Club dinner. "Did you hear that, everyone?" says the entertainer. "This lovely lady is just seventy years young! And she doesn't look a day over fifty. " He has been careful not to use the word "old". In a society where youth is so admired, old age is often seen as something sad, something to fight against. Americans prefer not to say "old" people. They use the expression "senior citizens". They do not talk about "old people's" homes, but "retirement" homes. In fact, the entertainer is not so wrong. Seventy is not very old these days. People in theprefix = st1 /USare living longer and longer. In1980, 12 percent of Americans were over sixty-five years old. By 2030, 21 percent will be over sixty-five. One reason for this is that families are getting smaller. The average couple now has only 1. 8 children. At the same time, improved medical care means that people are living longer. This change in the age of Americans is going to have serious results. For one thing, medical costs are rising. The government is unable to pay the elderly people's medical bills that have gone up very much. Some old people have to leave hospital "sicker and quicker" than they should, before they are really better. More fortunate senior citizens, though, who still have good health, want new laws to be passed to allow them to stay at work. In the past, the retirement age was sixty-five, but that is changing now. Older people are stronger and more energetic than ever before. Many of them refuse to stop working just because they have reached a certain age. There is a change, too, in the way in which elderly people see themselves. _ are no longer happy to accept the gray hair, bald heads, and boring clothes of their own parents. They like to wear younger-looking clothes and bright makeup . American women spend millions of dollars a year on operations to lift their faces and make those ugly wrinkles disappear. Men are prepared to spend even more on operations to plant new hair on their bald spots. It's worth any money to look younger. Which of the following is not the result of the changing in the age of Americans?

A new study done by the Higher Education Quality Council of Ontario (HEQCO) shows that it doesn't make much of a difference that parents reward their children with cash for their better marks. Many parents have offered cash to their children in the hope that it would improve marks and possibly raise their children's interest in achieving higher marks. The study, conducted by researchers from the University of Toronto (UT) and the Massachusetts Institute of Technology (MIT) to learn more about the potential for financial encouragement as motivation for improved marks, involved first and second year students receiving financial aid in 2008-2009 at the University of Toronto Scarborough. The top students participating in the study who said they were "very concerned" about having enough money to complete their degrees were to receive $100 for getting a grade of 70 per cent for each one-semester course, plus $20 for every percentage point beyond that.It was imaginable that a student could earn as much as $700 for achieving 100 percent in a course. Harvey Weingarten, president and CEO of HEQCO said, "In its efforts to help disadvantaged students by exploring the idea of paying them to attend school, the Toronto District School Board (TDSB) is asking the same question many other districts are asking about how to improve student participation and performance.Our study and others to date indicate that has little effect if any in those situations where it has been tested." The authors of the study suggest that ineffective study habits may be a barrier to academic achievement and that the real problem may be more a lack of academic preparation than a lack of effort or motivation.They note that the availability of peer advising does not appear to have helped greatly.They conclude that other potential avenues to improving performance, or other approaches of teaching, are needed at the high school and postsecondary levels. If a student gets a grade of 85% in a course, he will get _ .

Sometimes I really doubt whether there is love between my parents. Every day they are very busy trying to make money for my schooling. One day, my mother was sewing a quilt . I silently sat beside her. "Mum, is there love between you and Dad?" I asked in a very low voice. With surprise in her eyes, she stopped her work for a while. Then she said, "Susan, look at this thread . It can hardly be seen, but it' s really there. It makes the quilt strong. If life is a quilt, love should be a thread. Love is inside. " I couldn' t understand her until the next spring. At that time, my father suddenly got sick seriously. My mother had to stay with him in the hospital for a month. After they were back, my mother helped my father walk slowly on the country road every day. They were so kind to each other and it seemed they were the happiest couple. After two months my father still couldn' t walk by himself. "Dad, how are you feeling now?" I asked him one day. "Susan, don' t worry about me," he said. "I just like walking with your mum. I like this kind of life." Reading his eyes, I knew he loves my mother deeply. Now I understand that love is just a thread in the quilt of our life. Love is inside, making life strong and warm.

A primary school teacher asked her students to write a composition about what they would like God to do for them. At the end of the day, while marking the compositions, she read one that impressed her deeply. Her husband, who had just walked in, saw her crying and asked her, "What happened?" She answered, "Read this. It is one of my students' compositions." "Dear God, tonight I ask you for something very special: Make me into a television. I want to take its place and live like the TV in my house. Have my own special place, and have my family around me. To be taken seriously when I talk. I want to be the centre of attention and be heard without interruption or questions. I want to receive the same special care that the TV receives even when it is not working.

Meat and vegetables are measured in grams and kilograms. Milk and other liquid foods are measured in liters or milliliters. These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body. Our bodies use varying amount of calories. The more exercise we take, the more calories we burn. If we eat food which contains more calories than we use up, then it is possible that we would increase in weight. In order to avoid becoming overweight, it is advisable to eat a balanced diet and not eat too many foods that have a high calorie rating. The table below gives you some idea of the number of calories in food. Which is the best title of passage?

Now satellites are helping to forecast the weather. They are in space and they can reach any part of the world. The satellites take pictures of the atmosphere , because this is where the weather forms . They send these pictures to the weather station. So meteorologists can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change. Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead The main idea of this passage is that satellite is now used in _ .

Sometimes you may have a strong desire to do something strange or terrible. However, chances are that you don't act on your impulse , but let it pass instead. You know that to take the action is wrong in some way and that other people will not accept your behavior. Perhaps the most interesting thing about the phenomenon of _ behavior is how it can change over the years, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting that it was a taboo to even talk about them. Now with the publication of important books such asOn Death and DyingandLearning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject. One of the newest taboos is the topic of fat. Unlike many other taboos, fat is a topic that people talk about constantly. It's not taboo to talk about fat; it's taboo to be fat. The _ is thin, not fat. In the work world, most companies prefer youthful-looking, slim manager to sell their image as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline and self-respect. After all, how can people permit themselves to become fat? In an image-conscious society, thin is ''in", fat is "out". It' s not surprising that millions of people have become obsessed with staying slim and "in shape". The pursuit of a youthful physical appearance is not, however, the only reason for people's obsession with diet and exercise. Recent research has shown the importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of people has changed since last century. Modern machines do all the physical labor. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people's bodies can easily become weak. In an effort to avoid such a fate , millions of people are spending more of their time exercising. Parks are filled with joggers and bicyclists, and many companies are providing special exercise equipment for their employees to use during the work day. People pay more attention to diet and exercise because of _ .

Will online courses transform world of education? Some may wonder what it feels like to attend a class at Stanford University. The recently popular MOOCs (Massive Open Online Courses) can satisfy this desire. But they are also most likely to change the situation of higher education. Only last month,both Peking University and Tsinghua University announced plans to start open online course on the edX platform,one of the world's major providers of MOOCs,to explore this new form of online education. Gaining momentum "It's not only a change of platforms from offline to online. It's more about a reform of teaching methods,even the whole education system,"said Chen Jining,president of Tsinghua University. The potential of MOOCs to reform education has been obvious in the US ever since the immediate popularity of the course Artificial Intelligence,taught by Stanford University professor Sebastian Thrun, who later co-founded Udacity, a platform with 1.6 million enrolled students in 200 countries. According to Nature magazine,by June 2013,74 percent of universities in the US offered some type of online course. Lu Fang, vice-president of Fudan University,explains the appeal of MOOCs as a simple case of supply and demand:"The demand for high quality educational resources from both enrolled students and professionals is feeding the rise of MOOCs,in which classes usually taught by top teachers are available to everyone,"said Lu. Too early to replace With easy access and free of charge, MOOCs are said to have the potential to change the present education system. But there are barriers,because hardly any universities offer degree certificates, as college administrators point out, it's difficult to confirm if students are foaming anything in MOOCs,reposed USA Today. The Wall Street Journal also reposed that,presently,a typical MOOC student is likely to have already graduated from college and is using the course to explore an interest or acquire professional skills. Even so, an increasing number of undergraduates are signing up. "What we are really establishing are educational pathways for people who want skills that are related to contemporary jobs,"Thrun told The Wall Street Journal. MOOCs have been considered likely to reform education since _ .

Too much eating. Too many unhealthy foods. Too many ads for food. Too few activities. Different reasons are given for America's weight problem---a problem increasingly shared by other countries. Almost one-fifth of American children and teenagers are overweight. Schools have been asked to increase physical education, an important tool for public health. However, a recent study has shown an increase in the number of injuries in P.E. classes. Researchers say one possible reason for this is a decrease in the number of school nurses. Schools without a nurse on duty may be more likely to send an injured child to a hospital. Another possible reason for more injuries is a change in the traditional idea of physical education. This "New P.E." expands the kinds of sports that are taught. But activities that some schools offer now, like rock climbing and skateboarding, can also increase the risks, says Cheryl Richardson, who is with the National Association for Sport and Physical Education(NASPE). She also says not all states require P.E. teachers to be specially trained. Untrained teachers could be less likely to recognize unsafe conditions. Cheryl Richardson points to one of the study's findings -that injuries are often the result of contact with a person or a structure. This tells her that the teachers were not giving each student enough space to move around safely. Six activities produced seventy percent of all injuries: running, basketball, football, volleyball, rugby and gymnastics. The researchers say larger class sizes are another possible reason for the increase in injuries. Larger classes can mean less supervision . The National Association for Sport and Physical Education says twenty to thirty students in a P.E. class should be the limit. According to Cheryl Richardson, _ .

Competition between international universities is heating up, as China grows as one of the largest exporters of students aiming to study abroad. "Lots of universities are becoming more and more aggressive to attract Chinese students. Every day I receive contacts from universities in the US expressing the desire to come to China to recruit students," said Frank Joseph, a commercial officer from embassy of the United States. One key reason why more Chinese students are able to study abroad is the economy: With China's boom within the past decade, more families have the financial wherewithal to send their children to international universities. There will be a total of 200,000 family-funded Chinese students studying overseas in 2009, up 20 percent from last year, said Wu Zaofeng, deputy secretary general of China Education Association for International Exchange. International institutions, Joseph said, are also facing increasingly tough financial situation with a shortage of domestic students and a drop in government subsidies . Students, especially in the US are paying high tuition fees and living expenses. Chinese students with money to spend, according to experts, can fill up the gap. Students on average spend 150,000 yuan to 200,000 yuan every year studying in US, according to statistics from the US Institute of International Education. During 2007-2008, there were approximately 81,000 Chinese students studying in the US, up 19.8 percent from 2006. Representatives from approximately 60 universities from the United States are planning to arrive in Beijing this weekend to attract more Chinese students at this year's fair. Besides the US, many other countries are also vying to enroll Chinese students. Post-study work visa put out by British government allows all international students completing a UK degree qualification to apply for a visa to stay on and look for work in UK for up to 2 years. Being the third most popular destination for international students next to the US and the UK, France has set up two types of scholarships and has handed out an increase of 26 percent in scholarship funds to Chinese students in recent years. Which of the following statements is true?

Poor Oral Health Leads to Social and Emotional Problems A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems. Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection. The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries. "Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too." He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations. "It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation." Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods. But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less. Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments. What is the writer's attitude towards tooth decay?

China has mapped out plans for its new launches in the Shenzhou program on the next flight. But one conclusion seems to have escaped most reports in the aerospace media.The flight of Shenzhou 7 could be timed to coincide with the Beijing Olympics. Plans for 2008 Summer Olympics call for the events to be held between the 8th and 24th of August in that year. It's reasonable to expect that China will use the event to display its achievements before the world, and human spaceflight is China's most significant recent breakthrough. Shenzhou 7, China's next manned space mission, was originally advertised for 2007.This fit the pattern of staging a two-gap between crewed Shenzhou missions, which have previously launched in 2003 and 2005.But Chinese media statements have amended this to 2008.Chinese media have reported that the whole program is going well, more time is needed to work on spacesuit that will be used on this flight to stage China's first spacewalk. It's possible that Chinese engineers want to make best preparations for this complex mission. China could intend to carry out the mission of Shenzhou 7 just as media attention is focused on the lead--up to the Olympics. The crew of the fight, and possibly China's other flown astronauts, could then take part in the opening ceremony. China has previously honnoured her space travelers in great celebrations, such as the Hong Kong event that saw Yang Liwei singing with Jacky Chan. What would be the best title for this passage?

The computer is fast, and never makes a mistake, while people are too slow, and full of mistakes sometimes. That's what people often say when they talk about computers. For over a quarter of a century, scientists have been making better and better computers. Now a computer can do a lot of everyday jobs wonderfully. It is widely used in factories, hospitals, post offices and airports. A computer can report, decide and control in almost every field. Many computer scientists are now thinking of making the computer "think" like a man. With the help of a person, a computer can draw pictures, write music, talk with people, play chess, recognize voices, translate languages and so on. Perhaps computers will one day really think and feel. Do you think the people will be afraid when they find that the computer is too clever to listen to and serve the people? What will happen in the future?

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

New software is able to analyze exactly how many hairs there are in a patch of skin and could help in testing the effectiveness of baldness treatments and depilatory creams, say Australian researchers. Researchers from CSIRO Mathematical and Information Sciences in prefix = st1 /Sydneyreport their findings in the November issue of the journalSkin Research and Technology. The software, developed with a UKcompany, will make it easier for researchers developing hair removal creams to accurately assess how well they work, says Dr Pascal Vallotton. "Up to now they were counting the number of hairs that survived after treatment by hand. That's hard work and it's difficult because you may count a hair twice or you may miss it." he said. The software relies on images captured by a small flatbed scanner pressed onto the skin. Using a mathematical algorithm , the software then identifies and traces each individual hair based on an understanding of a hair's unique features, such as its straightness. The software is able to distinguish between hairs and other features on the skin such as wounds or moles . "Our skin irregularities make it difficult to say this is a hair or this is a mole," Dr Vallotton said. Comparison between earlier and later images can also determine if hair is growing quickly or slowly, he says. Unfortunately, to check the accuracy of the software, the researchers still had to adopt the old-fashioned method of counting hairs, helped by volunteers from neighboring labs who put their skins on the line for science. "We had 12 volunteers, mostly from neighboring labs, and we acquired images of hair before and after treatment," Dr Vallotton said. To ensure an accurate count, the individual hairs had to be marked off as they were counted, but after such a laborious process, the researchers were pleased to discover the software results were comparable to the manual count. Dr Vallotton says the software could also be useful in testing the effectiveness of balding treatments and counting or tracing substances other than hairs, that are long and thin and otherwise difficult to image.

Not everyone goes to university after high school graduation. Some work, others join the army and an increasing number worldwide are taking a "gap year" to travel or do community service in their own countries or abroad. They are studying sharks off the Australian coast, building schools in Mexico and learning Spanish or Italian. The concept of a gap year may not be new, but the recent surge of interest certainly is. Some students are putting off admissions. Others, who don't get into the college of their choice, are taking a year to explore new frontiers before reapplying. Students are choosing to take a breather; they are thinking. They are not sure what they are going to do. They are going and exploring some of their interests. They are getting experience they can take to the school they finally go to. It is an idea actively encouraged by colleges. Princeton University has just launched a "bridge year" program that will send 10 percent of its incoming class to do volunteer work abroad, starting in 2009. And the Harvard has spent the last 30 years urging incoming students to take a gap year. "Many speak of their year away as a 'life-changing' experience or a 'turning point'" says Harvard admissions director Marlin Lewis. "Many come to college with new opinions about their academic plans, their extracurricular interests and the career possibilities they observed in their year away."

Living in the desert is really hard! With less than 10 inches of rainfall a year, deserts are dry all year round. Lots of heat from the sun and a shortage of water are just a few of the challenges facing desert animals. Deserts are homes to many animals and plants. Few large animals have got used to life in the desert because their size makes it difficult to find shelter from the heat and they can't store water. In order to survive, desert animals have developed a number of ways to live in their special habitat. The most common way is staying under plants or rocks or digging underground in the heat of the day. And many desert animals stay in shelter during the day and hunt at night when it is cool. Some animals get the water they need from the insects, plants and seeds they eat, and do not need to drink. They do not have sweat glands and pass only small amount of waste water. Some animals develop their own ways of surviving in deserts. The Thorny Devil is a kind of lizard that lives in Australian desert areas. It has a body that channels raindrops directly into its mouth when it rains. Water-holding frogs spend most of the year underground in Australian desert areas, and develop a sort of cocoon that enables them to store water to keep them going through the dry times. When it rains, they come out to lay their eggs in ponds. The eggs hatch within days and develop quickly, before the water dries out. According to the text, the most widely used way for animals to survive in deserts is to _ .

Look closely at ,your hands-are they clean? It doesn't matter how many times you was your hands. They're still crowded with microbes, which are also called "germs" or "bacteria". Microbes are everywhere. But don't worry-most microbes don't harm you. and many actually help you stay alive. Now, scientists say the microbes that live on our hands could be used in a surprising way: fighting crime. When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal. But according to a recent study, investigators could even use microbes to help break a criminal case. Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody's hand is unique-much like one's fingerprint. The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find. And policemen use forensics such as studying fingerprints to identify the criminal. "Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists. "You can't sterilize(......) a surface just by wiping it off. " His team compared the bacteria on the hands of 273 people with the bacteria found on each person's computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son's hands matched the mix of microbes on that person's keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards. But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful. Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool. We can learn from the passage that _ .

Scientists have found that human eyes are more likely to be damaged by UV rays while skiing in the snow-covered areas than sitting on the beach, according to a report by the UK newspaper The Telegraph. The researchers at Kanazawa Medical University, Japan and American company Johnson conducted the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail (a rough path) in Ishikawa District, northern Japan. They compared the results with the levels of UV rays on a sand beach in southern Japan's Okinawa District. They found that on the beach, eyes are exposed to a daily 260 kilojoules of UV a square meter compared to 658 kilojoules in snow-covered areas. The findings are supported by the Japan Meteorological Agency. According to the agency, the reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height. Most of us know that UV rays can harm the skin. That's why we wear sunscreen on our skin before we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes. If your eyes are exposed to large amounts of UV radiation over a short period of time, you may experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes permanent damage to the eyes. Long-term exposure to UV radiation, however, can be more serious. Scientific studies and researches have shown that exposure to small amounts of UV radiation over a period of many years increases the chance of eye damage, which could lead to total blindness.

Dogs can know the meaning of a human perspective, say researchers. Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers. They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see. This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed. The study, published in Animal Cognition, conducted tests on eighty-four dogs. The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human. It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food. The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them. Juliane Kaminski carried out the research into how dogs are influenced by human circumstances. Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective". Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions. "Humans constantly attribute certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them," said Dr Kaminski. "These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability. Where can we probably read this kind of articles?

Mobile communications and the IP phone business have gradually replaced traditional long-distance calls. Mobile communications account for 28.5 percent of the total long-distance communications business. IP phones have 41.4 percent, while traditional long-distance calls are down to 30.1 percent. China Mobile, the country's largest mobile communication operator, has accounted for nearly 40 percent of taxes in the domestic telecom market. That puts it at the top of the six major telecom operators in the nation, according to the latest official statistics. The other five are: China Telecom, 31.1 percent; China Netcom, 16.6 percent; China Unicom, 13.4 percent; China Satellite Communications Corp and China Railcom, 1.5 percent. China Mobile is being chased by smaller rivals China Unicom and China Telecom, both of which are making significant 3G subscriber gains. That's aided in no small part by deals to offer the iPhone. However, as of March, China Mobile did have 15 million iPhone users on its network. In another ranking, Xiaomi, Huawei, Lenovo, vivo and OPPO came in as the top five mobile phone sellers in China by April, 2015, according to IHS Technology. The report also says that during this period, China produced 82 million handsets. (including GSM, GPRS and CDMA phones) and sold 80 million. Of the phones sold, 37 million were exported to other countries. Analysts point out that China's lack of core technologies and its heavy reliance on overseas technologies have proved to be an obstacle for development of domestic phone makers.

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet . When the fragments landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet? The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic. On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia. Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived. Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end? 55.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?

The Chang'e-3, named after a Chinese goddess, is China's first spacecraft to make a soft landing on the moon. It includes a lander and a moon rover called Yutu. The Chang'e-3 spacecraft is the second phase China's lunar rogramme, which includes orbiting, landing and returning to Earth. It follows the success of the Chang'e-1 and Chang'e-2 spacecraft in 2007 and 2010. The launch of Chang'e-3 was successful. The Chang'e-3 is one of the most difficult tasks in China's space programme, the news says. The news adds that exploring the universe and seeking peaceful use of space are dreams of Chinese for thousands of years. With a lander and the moon rover Yutu, Chang'e-3 soft-landed on the moon at 9:11 p.m. Saturday. Yutu later separated from the lander and ran to the moon surface earlier Sunday. China has chosen the name Yutu for its first moon rover, after a worldwide online vote attracted people to come up with names. In Chinese folk tale, Yutu is the white pet rabbit of Chang'e, the moon goddess. Chang'e took her pet and flew towards the moon. She became a goddess and has lived there with the white animal ever since. Which is the first spacecraft landed softly on the moon in China?

Electronics, such as laptops, mislead our minds into thinking that it is still daytime, preventing sleep and increasing the risk of _ . Sleep experts say human's natural body clock begins to rest and relax from the day between 9 and 10 pm but the use of computers confuses it. A person's brain biologically becomes awake when the sun is out because bright light after dark causes the brain to stop producing the hormone called melatonin that makes us sleepy. Researchers say blue light from devices such as iPads, which is expected to become a popular reading tool when it comes out later this month, is particularly disruptive during the night when the brain thinks it should be dark. Experts say a good book is a far better way of resting the brain and ensuring a good night's sleep because the bedside lamp light doesn't affect the brain as it does not look straight into a person's eyes. "Potentially, yes, if you're using an iPad or a laptop close to bedtime... that light can be stimulating to the brain to make it more awake and delay your ability to sleep," Phyllis Zee, a professor at Northwestern University and director of the school's Centre for Sleep & Circadian Biology, told CNN. "And I think more importantly, it could also be enough to affect your circadian rhythm. This is the clock in your brain that determines when you sleep and when you wake up. " Alon Avidan, associate director of the Sleep Disorders Center at the University of California Los Angeles, added, "I wish people would just take a boring book -- an oldfashioned book -- and read by a lamp." The bedside lamp light doesn't affect the brain because _ .

A young man worked very hard on his lessons. He was too busy to have a rest. One day he found that he couldn't fall asleep at night. As he became ill, he couldn't go to sleep. When he went to bed, he closed his eyes and tried to sleep. But he always failed. After a few days he decided to see a doctor. "I just can't go to sleep at night. What should I do?" he asked. "I have a suggestion," said the doctor. "You can try to count numbers. When you count to one thousand, you will be asleep. I am sure of it. " The next day the man returned to the doctor's office. "Well," said the doctor. "How are you today? Did you try my suggestion?" The man still looked tired. "Yes," he said. "I tried to count one, two, three.. , up to one thousand. But when I counted to five hundred and sixty--nine, I began to feel sleepy. I had to get up and drink some tea so that I could go on counting up to one thousand. But then I still couldn't fall asleep. " Why couldn't the young man go to sleep at night?

Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs , teachers find students' posture and attention improve. Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning. The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico and Japan," says Witt, " Research shows that sitting on the balls makes them sit up straighter . You can slouch on a ball," says Witt, "but it feels bad." Because the students are moving, their blood increases. That carries more oxygen( ) to the brain , so the kids have more energy and can pay attention longer. "Besides, they're fun." says Pownall. In how many countries are the balls used as the students' chairs?

They crossed in front of me as I was driving out of the store parking lot .I would be delayed for a whole ten seconds. However,I realized that it was an elderly couple who were briefly delaying my departure .No more anger. The man leaned on his wife who walked in front of him. He not only used her for support but it was obvious that he was blind. She was his eyes as well. The two of them worked as one--each needing the other to function in this fastchanging world. That little example of true strength that day changed my whole personal perception of life. Suddenly I wasn't so mad about having to work a few extra hours on Saturday. I had my strength,and I was still relatively young. That picture of those two elderly people walking with dignity and strength stayed with me the entire week. My life wasn't so bad after all. I had my health and a good job. My wife always gave me good advice whenever I needed it. I started to think--not only was I lucky to have it all,but so was that wonderful old couple,who,despite the trials and hardships of a long life,still had the love and support of each other to carry them through this world. There are so many people out there just like that couple. My wife and I sometimes picture ourselves in our old age,walking arminarm into the sunset. That image always gives us a warm feeling of comfort. Just remember,none of us would be here if it weren't for our elders. We should spend an extra minute to listen and learn when it comes to helping our elder friends. They need it. What was the author's first reaction when he was stopped by the old couple?

Homework and stress are rarely reduced inside the classroom.Meanwhile,outside the classroom,the pressure is on to find scholarships for college. According to Braintrack,a higher education database with worldwide reach,more than 3 billion US dollars (18 billion yuan) in private scholarships are awarded to college students annually.Average awards range from $2,000 to $3,000. The scholarship application process is similar to the college application process: forms to be completed,test scores and transcripts to be sent,essays to be written and often interviews to be prepared for. A few great places to start looking for scholarships are: www.fastweb. com,www.Finaid. org and www.collegexpress.com.Check out the annual scholarship guidebooks Scholarships,Grants & Prizes by Peterson's and the Ultimate Scholarship Book: Billions of Dollars in Scholarships,Grants and Prizes by Gen Tanabe and Kelly Tanabe. Be selective.Thoroughly research the qualifications required by each of the scholarships.Don't waste your time applying for those that are need based if you can't produce the appropriate documents. Research past recipients .Check out the websites of the organizations sponsoring the scholarships.Many post the biographies of past recipients.You don't need to have cured cancer,but if you don't think your resume measures up to the past winners',you might be better served by moving onto the next scholarship on your list.Prepare for the interview. You'll want to dazzle them with your personality,but above all you'll want to be prepareD. Find someone you trust to conduct a similar interview with you - someone who will be honest with you and provide valuable suggestions. Let your personality shine through in your essays.The essays are the best way for students to share who they are,where they've come from,what they've overcome and so on.Tell your story in an interesting and persuasive way.And if you do have an interview,send a thank you note afterward.

Is this a car? Is it a smart phone? Is it a gaming machine? Yes to all three. The Toyota Fun-Vii is a pleasure palace on wheels. If Toyota has its way, paint jobs could become a thing of the past, because it has introduced an amazing car that can change its whole look in an instant. The Vii in Fun-Vii, which stands for "Vehicle, Interactive, Internet" It is a small three-seater car that looks like a smart phone, so it is called a smart phone on wheels.Inside and out, most aspects of the car can interact with the internet and be controlled by a smart phone.The magical car allows the owners to download pictures from their phones onto the outside, so that the look of the car could be changed instantly.The color inside could also be changed to reflect the owner's mood.Just as the company president Akio Toyoda said, "A car must appeal to our emotions.If it's not fun, it's not a car." Its outside and inside are not made of solid paint but touch screens that can display pictures and videos.A network update function downloads all the latest software to make sure the car is always up-to-date, and it can provide the latest entertainment as well as information about its surroundings to the driver.As you drive around, the thoughtful car allows you to communicate with your friends in the nearby cars.It also helps you find your way from one place to another. It's all because the car is networked with all the other cars on the road and drives itself. The smart car is a practical, family sized vehicle fuelled by hydrogen, and it is one of the futuristic concept cars under the theme of "fun to drive, again".It heralds a not-too-distant future where people, cars and society are linked. We can infer from the text that the Fun-Vii _ .

Do you get enough sleep? With so much homework it's often difficult to get the rest you need. But you need to try, because sleep keeps you healthy and it stops you getting fat. Recently, a group of US scientists did a study of kids aged between 8 and 13. The study found that if kids sleep for just one extra hour each day, the chance of their getting fat is cut by about 30 percent . Why? When people don't get enough sleep, they become tired. When they are tired, they don't exercise enough. Also, kids like snacks: If they are awake an extra hour or two each day,they have more time to eat snacks or other unhealthy foods. So, how much sleep should you get? Scientists suggest 10 to 11 hours a night for kids aged 5 to 12. For older kids, _ . How many reasons are given why people might get fat without enough sleep?

As skies are filled with millions of migrating birds, European scientists say the seasonal wonder appears to be strange: The fatter the bird, tile better it flies. The results of their study led to a theory opposite to a central one of aerodynamics , which says that the power needed to fly increases with weight. For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think. Researchers found that red knot wading birds double their normal body weight of 100 grams before making their twice-a-year nonstop flight between the British Isles and the Russian Arctic. Distance: 5,000 kilometers. Another study in the magazine Nature measured the advantage of flying in an aerodynamic group which allows birds to save energy by flying smoothly and quietly in the lead bird' s air stream. Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri, a French scientist. The findings help explain how birds complete difficult migrations. Researchers had thought that thinner, stronger birds would have the best chance to survive. The first study suggests that building up fat to be burnt as fuel during the migration is worth more than the energy it takes to carry the additional weight. In the study, researchers said their team studied the birds flown at different body weights during 28 simulated flights. They forced a small amount of special water into the birds' bodies so that they could measure the amount of energy burnt during the flight. A _ red knot wading bird has a better chance to survive during its migrating flight.

Sometime in the next century, the familiar early-newspaper on the front porch will disappear. And instead of reading your newspaper, it will read to you. You'll get up and turn on the computer newspaper just like switching on the TV An electronic voice will distribute stories about the latest events, guided by a program that selects the type of news you want. You'll even get to choose the kind of voice you want to hear. Want more information on this brief story? A simple touch makes the entire text appear. Save it in your own personal computer if you like. These are among the predictions from communication experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers will unite print and broadcast reporting, and offer news and analysis with video images of news events. Most of the technology is available now, but convincing more people that they don't need to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry. Technology is making the end of ' traditional newspapers unavoidable. Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 t0 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry. Which of the following is a reason why it will take a long time to complete the changeover?

When you first arrive in Oxford, it may take a little while for you to find your way around. Some of the first things our students do when they arrive include finding a bike (most students in Oxford find cycling is the best way to go around), setting up a bank account, getting their computer and mobile phone working, finding their department, getting to know their college and working out the best places to socialize. One of the major events you will experience shortly after "coming up" to Oxford is matriculation. Matriculation is held at the University's Sheldonian Theatre and is the ceremony at which you are formally admitted to the university. International students are invited to an orientation day at the start of the academic year. Sessions run throughout the day that will give you practical information about living and studying in the UK and introduce you to other graduate students from all over the world who are starting their studies at Oxford at the same time as you, as well as to current Oxford graduate students and staff who will be able to help and advise you. The day covers topics such as studying and learning in the Oxford system, University services, information on living in Britain and cultural differences, as well as addressing practical issues such as employment, immigration and visas, health and safety. You can choose which talks to attend and at the end of the day there is a social hour so you can meet fellow students. Another good thing to experience early is college dining. Most colleges have a tradition of regular formal hall dinners, which consist of three or four courses, and the atmosphere of an evening out in a nice restaurant. On some of these occasions you can invite people around to your college for dinner and _ . In this way, you can get to know people studying your own and other subjects at the same time as visiting many of the historical college grounds and dining halls. For a newcomer to Oxford, what does he have to do first?

Ibrahim became disabled after contracting polio when he was three years old. At first his parents, like many other parents of disabled children in Niger, did not want to send him to school. They were worried he would be laughed at by his classmates. Despite his disability, and his parents' doubts, Ibrahim was determined to go to school. "When I was eight," Ibrahim says, "other kids of my age were going to school while I stayed at home. I did not like that. So, I pestered my parents until they finally let me go to school." Ibrahim's parents sent him to a private school nearby. Although the journey to and from school was a short one, it still wasn't easy for Ibrahim. He had to use his hands to help him move along, protecting them with plastic slippers. But at least he was getting an education. However, after only a year in school, Ibrahim's education was interrupted when his parents separated. His mother did not have the means to continue paying for his tuition. In 2007, Ibrahim received some money to be fitted with a leg brace , corrective shoes and his first pair of crutches . Now that he was more mobile than before, the most important thing for him was to find a way to go back to school. "I wanted to start school again last October," Ibrahim says. "After my mother told me she could not afford it, I went to visit some of my relatives for support. And I collected 5,000 francs CFA (US $8) to pay my tuition for half a year. I will find the rest of the money somehow." Ibrahim attends a school in which he is the only disabled student. According to his teacher, he is among the top five students in a class of 55.

Everyone takes drugs.Sometimes a drug might be called a herb but the effect is the same.Drugs and herbs can make life better for they are used to improve health.From the simplest headache to a cure for cancer, people believe that certain drugs can help them.But there is danger if the drugs are not used in a proper way. American teenagers sometimes use certain drugs to feel good.They call this "getting high".The problem is that once a young man or a young woman has the feeling of"getting high",they want to do it often.If school is boring or too hard,students might get depressed and a drug or herb might help them feel better.If the student takes too much of a drug,the body may change in a wrong way such as a confused mind,poor sight,a headache,and an uncomfortable stomach. Schools now have D.A.R.E.program which means Drug Abuse Resistance Education.This program was started so that young students from age 10 to 18 might understand how a drug affects their bodies.The main point of the program is education.Once a student understands certain drugs can cause ill health,he will know he should not use them. Education is the key to good nutrition as well.If a student eats correctly,he or she will be full of energy which leads to good study habits and good grades.Poor nutrition may cause the need for more sleep and poor concentration.Proper food is similar to the proper use of drugs.Both allow a healthy body to grow while misuse of them prevents a person from developing normally.

Scientists have discovered thirteen kinds of vitamins. They say vitamins help to carry out chemical changes within cells. If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases. Which foods should be eaten to keep us healthy? Let us look at some important vitamins. Vitamin A helps prevent skin and other tissues from becoming dry. People who do not get enough vitamin A cannot see well in darkness. Vitamin A is found in fish liver oil and the yellow part of eggs. Vitamin B-1 is also called thiamine. Thiamine changes starchy foods into energy. Thiamine is found not just in whole grains like brown rice, but also in beans and peas, nuts, and meat and fish. Vitamin B-12 is needed so folic acid can do its work. Together, they help produce red blood cells. Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy. Vitamin B-12 is found naturally in foods like eggs, meat, fish and milk products. Vitamin B-12 is found in green leafy vegetables and other foods, like legumes and citrus fruits . Vitamin C is needed for strong bones and teeth. The body stores little vitamin C. So we must get it every day in foods such as citrus fruits, tomatoes and uncooked cabbage. Vitamin D prevents the children's bone disease rickets . Ultraviolet light from the sun changes a substance in the skin into vitamin D. Fish liver oil also contains vitamin D. Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding. It can also be found in pork products, liver and in vegetables like cabbage, kale and spinach . Vitamins are important to our health. A lack of required vitamins can lead to health problems. According to the passage, taking in enough vitamin C can _ .

The research tracked the health of 101,000 US nurses over three decades. Light-to-moderate smokers were twice as likely to die of sudden heart problems as those who had never smoked. But those who quit smoking saw their risk begin to go back down within years, a journal of the American Heart Association reports. _ During the study, there were 315 sudden cardiac deaths ----where the heart unexpectedly stops working. In people aged 35 or younger, this usually because of a heart condition that runs in the family. But in people who are older than this--as most of the nurses in the study were --it can be the first sign of coronary heart disease, where the heart's arteries become blocked by fatty deposits. Of the 315 sudden deaths in the study, 75 were among current smokers, 148 were among recent or past smokers and 128 occurred in people who had never smoked. Reason to quit After taking into account other heart risk factors, such as high blood pressure, high cholesterol and family history of heart disease, Dr Roopinder Sandhu and his colleagues found the women who smoked were twice as likely as likely to die suddenly even if they smoked "light-to-moderate" amounts --between one and 14 cigarettes a day. For every five years of continued smoking, the risk went up by 8%. But women who quit saw their risk fall to that of someone who had never smoked, after 20 years of cessation. Dr Sandhu, of the University of Alberta, Canad, said: "What this study really tells women is how important it is to stop smoking. The benefits in terms of sudden cardiac death reduction are there for all women, not just those with established heart disease." "It can be difficult to quit. It needs to be a long-term goal. It's not always easily achievable and it may take more than one attempt." Ellen Mason, senior cardiac nurse at the British Heart Foundation, said: "This study shows that smoking just a couple of cigarettes a day could still seriously affect your future health." "As we approach the new year, many of us will be making resolutions and giving up smoking will be the top of the list for lots of people." "If you're thinking of quitting and need a _ , this research adds to the wealth of evidence that stopping smoking is the single best thing you can do for your heart health." A recent study in The Lancet of 1.2million Women found those who gave up smoking by the age of 30 would almost completely avoid the risk of dying early from tobacco-related diseases. Latest figures suggest a fifth of women in England smoke. According to the research, light smokers _ .

We have to accept the truth: Sometimes, we just want to shout out loud. For example, we all have days like this: our dog has made a mess on the floor we just cleaned, or our friend called to tell us he or she couldn't come at the last minute when we had cooked dinner for him or her. We may be really angry but we tried to bear things like those. According to ancient Chinese wisdom, we should shout in a loud voice instead of keeping silent. In fact, it's good for our health. "Chinese people have passed on the practice from ancient times to now as a part of traditional medicine," said Mrs. Li, a 60-year-old woman from Hangzhou. "My parents taught me to do this. It's a part of our folk culture. " Mrs. Li is a member of a group of people who love shouting. Each morning, she and some of her friends climb to the top of a hill and let out loud shouts before starting their daily exercise. They believe that shouting is good exercise for their lungs and it brings them a lot of fun. "Sometimes I shout out and other shout back," said Mrs. Gu, another shouting lover. "It makes you happy. You laugh and then you feel very comfortable. " Dr. Peter Calafiura, an American doctor, agrees that shouting can have a positive influence on people's health. So, next time you start your morning run, why not try to shout out first? It will make you healthier. Mrs. Li learnt to shout to make herself feel better from _ .

When I arrived in Beijing more than five years ago, I had already given blood 79 times. I wanted to continue to be a donor and asked around if there was a Red Cross clinic in Beijing. There was one, and I went. I was very surprised to be received as a hero; for me, a blood donation was simply a good habit and a gift of love to Humanity. In Canada, donors can give 450ml each time every 51 days. That means six times a year. In China, we can give only 200ml, every four months. In 1984, there were only 19 donors in Beijing who offered their blood for free. One year later, there were 141. In 1986, 1,083, and so on until the figure reached 10,046 in 1990,14,016 in 1992 and more than double that the following year. There were 41,037 in 1994, and my statistics stop here. I'm so glad to see that the Chinese have understood that giving blood is not dangerous, and that it's a way to say, in a real communist spirit, "brother, I love you". In fact, every time I give blood, I think of my blood running in a man or a woman's veins, someone who has become my brother or my sister through a transfusion. Thirteen Chinese have become my s now; isn't that great? Giving blood is like giving birth. Some of these thirteen people may have died without my donation; doesn't that make it worth becoming a volunteer? What makes me even happier is when I can convince a Chinese friend to come with me and become a donor too. Up till now, how many times have the author given blood?

In Western countries people have been using the installment plan since the first half of the twentieth century. Today, a large number of families in Great Britain buy furniture, household goods and cars by installments .In the U.S., the figure is much higher than in Great Britain, and people there spend over 10 percent of their income on the installment plan. The price of an article bought on installments is always higher than the price that would be paid by cash. There is a charge for interest. The buyers pays one quarter or one third of the price as a down payment when the goods are delivered to him. He then makes regular payments, weekly or monthly, until the full price is paid up. The legal ownership of the goods remains with the seller until the final payment has been made. Installment buying has advantages and disadvantages. It can help couples with small incomes to furnish their homes and start housekeeping, It increases the demand for goods, and in this way helps business and employment. There is ,however, the danger that when business is bad, installment buying may end suddenly, making business much worse. This may result in a great increase in unemployment. If the people on the installment plan lose their jobs, they will probably not be able to make their payments. If great numbers of people are not able to pay their installment debts there is a possibility that businessmen cannot collect their debts and will therefore lose money. If businessmen lose money or fail to make a satisfactory profit, it becomes more likely to have a depression. This is why, in some countries, the government controls the installment plan by fixing the amount of the down payment to discourage people from buying more than they can pay for on the installment plan. The advantages of installment buying might include all the followings EXCEPT that _ .
