In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:The more the man ran, the greater loss of body fat.The more they ran, the greater their increase in food intake.Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.1、What kind of physical problem do many adult Americans have?____A、They are too slim.B、They work too hard.C、They are too fat.D、 They lost too much body fat.2、Based upon the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have a "weight problem"?____A、 30.B、 50.C、100.D、150.3、Is there scientific evidence to support that eating too much is the cause of a "weight problem"?____A、Yes, there is plenty of evidence.B、Of course, there is some evidence to show this is true.C、There is hardly any scientific evidence to support this.D、We don't know because the information is not given4、In comparison with the adult American population today, the Americans of ____.A、ate more food and had more physical activitiesB、ate less food but had more activitiesC、 ate less food and had less physical exerciseD、had more weight problems5、What have modern medical and scientific researches reported to us?____A、Fat people eat less food and are less active.B、 Fat people eat more food than slim people and are more active.C、 Fat people eat more food than slim people but are less active.D、 Thin people run less, but have greater increase in food intake.

Passage 2
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to
eat. some research has shown that perhaps eighty percent of all human illness are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illness because of the food that is characteristic in these cultures.
That food related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in
our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful.
The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the
Food and Drug Administration （FDA） has tried repeatedly to control these procedures, the practices continue.
It can inferred from the passage that___.
A. Scientists have made all the food fit to eat.
B. Only in recent years have people found that the food is related to one’s illness.
C. All kinds of cancer are related to the diet.
D. Some additives are harmful to our health.

More Than 8 Hours Sleep Too Much of a Good Thing1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers.3 These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine,demonstrate that people who want to get a good night's rest may not need to set aside, more than 8 hours a night.He added that“it might be a good idea”for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cautioned that more research is needed to confirm this.4 Previous studies have shown the potential dangers of chronic shortages of sleep一for instance,one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.5 For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.6 Kridke found that people who slept between 9 and 10 hours each night were more like-ly to report experiencing each sleep problem than people who slept 8 hours.In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake.”he said.Paragraph 5______A: Kripke's ResearchB: Dangers of Habitual Shortages of SleepC: Criticism on Kripke's ReportD: A way of Overcoming InsomniaE: Sleep Problems of Long and Short SleepersF: Classification of Sleep Problems

Stomach UlcerStomach ulcers are the cause of severe pain for many people.Doctors have been able to help lessen the pain of ulcers.They could not cure them.Now doctors have discovered a cause of ulcers.This means they may have found a way to cure people who suffer from the stomach pain.Studies show that ten percent of the population will develop an ulcer at some time in their lives.So a possible cure is good news for many people.Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in the stomach then increase the pain of an ulcer. How does a person know he or she has an ulcer? Doctors say most people with ulcers feel a burning pain in their chests or stomachs.This pain is often called heartburn.It usually happens before eating or during the night. It causes some people to lose their desire to eat,or they are unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H Pilorie.H Pilorie bacteria are what make stomach produce extra stomach fluid.Doctors found that they can kill the bacteria with medicines called antibiotics.Health expertssay the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs.They also believe curing ulcers will reduce the number of people who develop stomach cancer. The number of people with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.Doctors say a person is more likely to get an ulcer if someone in his or her family has had one.In fact a person with the family history of ulcers is three times more likely to get one than other people.There are ways people can protect themselves from developing an ulcer.

How Technology Pushes Down Prices1 Prices have fallen in the food business because of advances in food production and distribution tech- nology.Consumers have benefited greatly from those advances.People who predicted that the world would run out of food were wrong. We are producing more and more food with less and less capital.Food is there- fore more plentiful and cheaper than it has ever been.Spending on food compared with other goods has fallen for many years,and continues to drop.2 Supermarkets have helped push down prices mainly because of their scale.Like any big business, they can invest in IT systems that make them efficient. And their size allows them to buy in bulk.As super- markets get bigger,the prices get lower.3 Huge retail companies such as Wal-Mart have tremendous power and they can put pressure on pro- ducers to cut their margins.As a result,some producers have had to make cuts.In recent years,Unilever has cut its workforce by 33,000 to 245,000 and dropped lots of its minor brands as part of its"path to growth"strategy.Cadbury has shut nearly 20 per cent of its 133 factories and cut 10 per cent of its 55,000 global workforce.These cuts help keep costs down,and the price of food stays low.4 Does cheap food make people unhealthy?Cheap food may encourage people to eat more.Food corn- panies certainly think that giving people more food for their money makes them buy more.Giving people bigger portions is an easy way of making them feel they have got a better deal.That is why portions have got larger and larger. In America,soft drinks came in 80z(225 g)cans in the past,then 120z(350g),and now come in 200z(550g)cans.If a company can sell you an 80z portion for$7,they can sell you a 120zportion for$8.The only extra cost to the company is the food,which probably costs 25 cents.5 Now companies are under pressure to stop selling bigger portions for less money.But it is hard to change the trend.Some food producers have reduced__________.A:their workforceB:huge portionsC:large quantitiesD:their moneyE:a good bargainF: minor brands

Around the world more and more people are taking part in dangerous sports and activities．Of course，there have always been people who have looked for adventure--those who have climbed the highest mountains，explored（探险）unknown parts of the world or sailed in small boats across the greatest oceans．Now，however，there are people who seek（寻找）an immediate thrill（令人激动的事情）from a risky activity which may only last a few minutes or even seconds．
I?would consider bungee（蹦极）jumping to be a good example of such an aetwity．You jump?from a high place（perhaps a bridge or a hot air balloon）200 metres above the ground with an elas-tic（弹性的）rope tied to your ankles．You fall at up to 150 kilometres an hour until the rope stops you from hitting the ground．It is estimated that 2 million people around the world have now tried bungee jumping．Other activities which most people would say are as risky as bungee jumping involve（包括）jumping from tall buildings and diving into the sea from the top of high cliffs．
Why do people take part in such activities as these?Some psychologists（心理学家）suggestthat it is because life in modern societies has become safe and borin9．Not very long ago，people’s lives were constantly under threat．They had to go out and hunt for food，diseases could not easily be cured，and life was a continuous battle for survival．
Nowadays，according to many people，life offers little excitement．They live and work in?comparatively safe environments;they buy food in shops;and there are doctors and hospitals to look?after them if they become ill.The answer for some of these people is to seek danger in activities such?as bungee jumping.
People probably take part in dangerous sports nowadays because__________.A.they have a lot of free time
B.they can go to hospital if they are injured
C.their lives lack excitement
D.they no longer need to hunt for food

It seems obvious that you don"t give away your product for free but this is exactly what indie rock group The Crimea did earlier this year. The band"s reasoning goes like this: more people will download the free album than would pay for it. Therefore more people will heat. The Crimea"s music. These people will then pay money for concerts by the band and perhaps buy a T-shirt or other merchandise. If the band play regular concerts to crowds of 200 or 300 people they can make more money than they would from sales of a CD. There will always be some people who want something they can hold in their hands so they will release the CD into the shops too—but making money through sales of their music isn"t the top priority.
The story illustrates the creative thinking going on in the music business in response to dramatic changes over the last few years in the way that people buy music. Sales of music digitally—to computer, phones and MP3 players rose to $2 billion in 2006—an increase of almost 100 percent on the previous year—yet overall record company sales are down. People are simply not buying CDs in record shops in anything like the numbers they used to.
This trend looks set to continue, so the big question for the music industry is whether they can successfully manage the move to being primarily a digital industry without profits falling to unacceptable levels.
There are both positive and negative signs. On the plus side, more and more people are buying music on mobile phones, which allows people to make impulse purchases—they can buy a song as soon as they hear it. Research by the UK mobile operator 3 suggested that 75 percent of 16 to 24-year-olds wanted to buy a track they liked as soon as they heard it. With so much competition for people"s disposable income, a product that you can sell immediately is a big advantage.
The bad news for record companies, however, is the amount of music that is downloaded illegally. Piracy—usually in the form of cheaply copied CD—has long been an issue for the music business but the Internet means music can be copied and distributed freely through file-sharing sites on a large scale than ever before.
It is this situation that leads bands to start giving away their music for free and promises to make the next few years a very interesting time in the music business.The Crimea also released CDs for sale in shops because （）.A、people who attend their concerts need themB、they want to make extra moneyC、there are still people who prefer CDs to other formatsD、people who fail to attend their concerts need them

问答题Practice 2 Prices have fallen in the food business because of advances in food production and distribution technology. Consumers have benefited greatly from those advances. People who predicted that the world would run out of food were wrong. We are producing more and more food with less and less capital. Food is therefore more plentiful and cheaper than it has ever been. Spending on food compared with other goods has fallen for many years, and continues to drop. Supermarkets have helped push down prices mainly because of their scale. Like any big business, they can invest in IT systems that make them efficient. And their size allows them to buy in bulk. As supermarkets get bigger, the prices get lower. Huge retail companies such as Wal-Mart have tremendous power and they can put pressure on producers to cut their margins. As a result, some producers have had to make cuts. In recent years, Unilever has cut its workforce by 33,000 to 245,000 and dropped lots of its minor brands as part of its “path to growth” strategy. Cadbury has shut nearly 20 per cent of its 133 factories and cut 10 per cent of its 55,000 global workforce. These cuts help keep costs down, and the price of food stays low. Does cheap food make people unhealthy? Cheap food may encourage people to eat more. Food companies certainly think that giving people more food for their money makes them buy more. Giving people bigger portions is an easy way of making them feel they have got a better deal. That is why portions have got larger and larger. In America, soft drinks came in 8oz (225g) cans in the past, then 12oz (350g), and now come in 20oz (550g) cans. If a company can sell you an 8oz portion for $ 7, they can sell you a 12oz portion for $ 8. The only extra cost to the company is the food, which probably costs 25 cents. Now companies are under pressure to stop selling bigger portions for less money. But it is hard to change the trend.

单选题Passage1 Questions 1 to 5 are based on the following passage. It's interesting that the arrival of snow has the effect on people in different countries.(76) For some countries it is an important happening to celebrate each year, while for others a catastrophe （灾害） or even a wonder. But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year.Britain is one of them, for which the arrival of snow quite simply creates problems.Within hours of the first snowfalls, however light, roads are blocked; trains and buses have to stop in the middle of the way.Normal communications are affected as well: telephone calls become difficult and the post immediately takes more time than usual.And almost within hours there are also certain shortages-bread, vegetables and other things-not because all these things can no longer be produced or sent to shops,but mainly because people are frightened and go out and store up with food and so on...just for fear that something bad should happen. But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don't have such problems.It is simply because there is not enough planning and preparation.We need money to buy equipment to deal with snow and ice.To keep the roads clear, for example,requires snow-ploughs (扫雪机) and machines to spread salt.(77) The reason why a country like Britain does not buy snow-ploughs is that they are only used for a few days in any one year, and the money could be more useful in other things such as hospitals, education, helping the old, and so on.3 After a few hours' snowing there are often some shortages of food because______.A
shops have closed downB
people buy as much as they canC
farmers can produce no moreD
people eat more vegetables
