题目内容

The centerpiece of curling(冰壶)is the curling stone, which has been called a “geometrical masterpiece of tooled geology (地质). ” Kays of Scotland has been making curling stones since 1851, when William Kay and his sons Andrew and Thomas set up a workshop in Mauchline, Ayrshire , in southwest Scotland. Kays is still owned by the relatives of the founder, and today it is the only curling stone maker left in Scotland.

Used in a highly competitive sport, the curling stones are made to exact standards. First, stones are sliced and then into round “cheeses”. Finally , the cheeses are shaped and polished into curling stones in a series of precise steps.

Each stone must weigh 44 pounds. Each must have a maximum diameter (直径) of 36 inches. Polishing is done by hand on a wheel using water, diamond-talcum power, and felt. Finishing the stone’s “running edge” is done entirely by hand with a special kind of paper and a digital measure and magnifying glass (放大镜). Lastly, a handle is fitted into holes on the top of the stone. Stones are computer-matched into pairs. Sixteen stones -8pairs-are needed for a game, and since curling game field usually have 6 lanes, each game field needs 96 matched stones!

Kays is a small firm, employing than ten skilled workers. Master craftsman and co-owner James Wyllie is skilled at all phases of curling stone making and is also an enthusiastic curler, as well as active member of Mauchline’s Burns Club, which meets regularly to honor well-known Mauchline residents.

59．What IS true about Kays?

A．It is a family business． B．It’s a brand of curling stones．

C．It’s a place in Scotland． D．It’s the name of a curling stone dealer．

60．How many curling stones are needed for two games happening at the same time?

A．8． B．16． C．32． D．96．

61．Which of the following shows the right process of making a curling stone?

A. Slicing—shaping—polishing．

B．Weighing—measuring—polishing．

C. Cutting—running—edging—computer—matching

D. Cutting—measuring——shaping——polishing

Money spent on advertising is money spent as well as any I know of. It serves directly to assist a rapid distribution of goods at reasonable prices, thereby establishing a firm home market and so making it possible to provide for export at competitive prices. By drawing attention to new ideas it helps enormously to raise standards of living. By helping to increase demand it ensures an increased need for labor, and is therefore an effective way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television license would need to be doubled, and travel by bus or tube would cost 20 per cent more.

And perhaps most important of all, advertising provides a guarantee of reasonable value in the products and services you buy. Apart from the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for mercifully the public has the good sense not to buy the inferior article more than once. If you see an article consistently advertised, it is the surest proof I know that the article does what is claimed for it, and that it represents good value.

By the first sentence of the passage, the author means that______.

A. he is fairly familiar with the cost of advertising

B. everybody knows well that advertising is money consuming

C. advertising costs money like everything else

D. it is worthwhile to spend money on advertising

B. no advertiser dare promote a product that can't live up to the promise of his advertisement.

C. if an article is consistently advertised, it probably has good value.

D. with advertisements, you have to pay more for the goods or services you need.

From the passage, we can draw a conclusion that____.

A. the most importance of advertisements is to lower the cost of many services

B. the twenty-seven Acts of Parliament made misleading advertisements unable to exist

C. advertising assists a rapid distribution of goods, thereby do good to the import at good prices

Putting in water fountains (饮水器) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal Pediatrics.

The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutritionist(营养学家) at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage consumption(饮料消费量).

At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.

At the beginning of the study, there were no big differences in the number of overweight children in the different groups. But by the end of the school year, children in the schools with water fountains were 31 per cent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.

Children in the schools with fountains increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.

The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite (食欲).

1.What do we know about the survey from the passage?

A. The teachers were also encouraged to drink water.

B. The students surveyed were all overweight.

C. It surveyed children in the countryside.

D. It lasted for a whole school year.

2. What can be learned from the last paragraph?

A. Drinking water certainly decreases appetite.

B. Further research is needed to confirm the finding.

C. The experts will encourage all the students to drink water.

D. Why students drinking more get less pounds will be clear soon.

3. What would be the best title for the passage?

A. Schools with water fountains

B. Drink more water and become thinner

C. Water fountains at schools help kids stay thin

D. Water consumption at some German schools

Antidepressant（抗忧郁）drugs such as Prozac were viewed in the early 1900's as wonder pills that would remove depressive blues for good. But in the past five years, growing scientific evidence has shown these drugs work for only a minority of people. And now a research journal says that these antidepressants can make many patients' depression worse. This alarming suggestion centres on the very chemical that is targeted by antidepressants-serotonin（血清素）. Drugs such as Prozac are known as selective serotonin re-uptake inhibitors（or SSRIs）. Their aim is to increase the level of this “feel-good” chemical in the brain.

But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study's lead researcher Paul Andrews. “ We need to be much more cautious about use of these drugs,” says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada.

Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before.

“After long use, when a patient stops taking SSRIs, the brain will lower its levels of serotonin production,” he says, adding that it also changes the way receptors in the brain respond to serotonin, making the brain less sensitive to the chemical. These changes are believed to be temporary, but studies indicate that the effects may continue for up to two years.

Most disturbingly of all, Andrews' review features three recent studies which, he says , show that elderly antidepressant users are more likely to die earlier than non-users, even after taking other important variables into account. One study, published in the British Medical Journal last year, found patients given SSRIs were more than 4 per cent more likely to die in the next year than those not on the drugs.

“Serotonin is an ancient chemical,” says Andrews. “It is regulating many different processes, and when you disturb these things, you can expect that it is going to cause some harm.”

Stafford Lightman, professor of medicine at the University of Bristol, and a leading UK expert in brain chemicals and hormones, says Andrews’ review highlights some important problems, yet it should also be taken with a pinch of salt. “This report is doing the opposite of what drug companies do,” he says. “Drug companies selectively present all the positives in their research, while this search selectively presents all the negatives that can be found. Nevertheless, Andrews' study is useful in that it is always worth pointing out that there is a downside to any medicine. ” Professor Lightman adds that there is still a great deal we don't know about SSRIs-not least what they actually do in our brains.

When it comes to understanding why the drugs work only for a limited part of patients, U.S. scientists think they might now have the answer. They think that in many depressed patients, it’s not only the lack of feel-good serotonin causing their depression, but also a failure in the area of the brain that produces new cells throughout our lives. This area, the hippocampus, is also responsible for regulating mood and memory. Research suggests that in patients whose hippocampus has lost the ability to produce new cells, SSRIs do not bring any benefit.

A Battery’s Worst Nightmare(噩梦)

Portable electronics that can be carried about easily are only as good as their batteries and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life!When the fuel runs out in your laptop or mobile phone, you just fill up and go.

The engine, about the size of a ten-cent coin, starts with a combustion chamber (燃烧室) that burns hydrogen (氢). Its tiny parts are etched onto silicon wafers (硅片) in the same manner that computer parts are imprinted onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.

But the devil in all this nice detail is efficiency(效率). Tiny engine parts don’t always behave like their scaled-up parts of the first engine. Something between the parts can slow down the work, according to Columbia University professor Luc Frechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.

The scientists’ goal is to create an engine that will operate 10 times better than batteries do. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t available until at least the end of the next ten years.
