Being locked in a small room called a “calorimeter“ (热量测量室 ) is one way to find out. 1 The signs above the two rooms read simply “

18、Chamber One“ and “Chamber Two“. These are the calorimeters: 4m by 2m white-walled rooms where human volunteers are locked up in the name of science. Outside these. rooms another sign reads “Please do not enter - work in progress“ and in front of the rooms advanced machinery registers every move the

19、volunteers make. Each day, meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer. 2 Nicola Waiters is one of twenty volunteers who, over the past eight months, have spent varying periods inside the calorimeter. Tall and slim, Nicola does n

20、ot have a weight problem, but thought the strict diet might help with her training and fitness programme. A self-employed community dance worker, she was able to fit the experiment in around her work. She saw an advert for volunteers at her local gym and as she is interested in the whole area of die

21、t and exercise, she thought she would help out. 3 The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room. This sequence was repeated four times over six weeks. She arrived at the calorimeter at 8:30 am on each of the four mornings and from then on eve

22、rything she ate or drank was carefully measured. Her every move was noted too, her daily exercise routine timed to the last second. At regular intervals, after eating, she filled in forms about how hungry she felt and samples were taken for analysis. 4 The scientists help volunteers impose a kind of

23、 order on the long days they face in the room. “The first time, I only took one video and a book, but it was OK because I watched TV the rest of the time,“ says Nicola. And twice a day she used the exercise bike. She pedaled (踩踏板 ) for half an hour, watched by researchers to make sure she didnt go t

24、oo fast. 5 It seems that some foods encourage you to eat more, while others satisfy you quickly. Volunteers are already showing that high-fat diets are less likely to make you feel full.

28、 1个最佳选项。 31 Is the Tie a Necessity? Ties, or neckties, have been a symbol of politeness and elegance in Britain for centuries. But the casual Prime Minister Tony Blair has problems with them. Reports suggest that even the civil servants may stop wearing ties. So, are the famously formal British real

29、ly going to abandon the neckties? Maybe. Last week, the UKs Cabinet Secretary Andrew Turnbull openly welcomed a tieless era. He hinted that civil servants would soon be free of the costliest 12 inches of fabric that most men ever buy in their lives. In fact, Blair showed this attitude when he had hi

30、s first guests to a cocktail party. Many of them were celebrities (知名人士 ) without ties, which would have been unimaginable even in the recent past. For some more conservative British, the tie is a must for proper appearance. Earlier, Labor leader Jim Callaghan said he would have died rather than hav

31、e his children seen in public without a tie. For people like Callaghan, the tie was a sign of being complete, of showing respect. Men were supposed to wear a tie when going to church, to work in the office, to a party - almost every social occasion. But today, people have begun to accept a casual st

32、yle even for formal occasions. The origin of the tie is tricky. It started as something called simply a “band“. The term could mean anything around a mans neck. It appeared in finer ways in the 1630s. Frenchmen showed a love of this particular fashion statement. Their neckwear (颈饰 ) impressed Charle

33、s II, the king of England who was exiled (流放 ) to France at that time. When he returned to England in 1660, he brought this new fashion item along with him. It wasnt, however, until the late 18th century that fancy young men introduced a more colorful, flowing piece of cloth that eventually became k

34、nown as the tie. Then, clubs, military institutions and schools began to use colored and patterned ties to indicate the wearers membership in the late 19th century. After that, the tie became a necessary item of clothing for British gentlemen. But now, even gentlemen are getting tired of ties. Anywa

35、y, the day feels a bit easier when you wake up without having to decide which tie suits you and your mood. 31 The tie symbolizes all of the following except （ A） respect. （ B） elegance. （ C） politeness. （ D） democracy. 32 Why does Blair sometimes show up in a formal event without a tie? （ A） Because

36、 he wants to make a show. （ B） Because he wants to attract attention. （ C） Because ties are costly. （ D） Because he wants to live in a casual way. 33 Which of the following is NOT a social occasion? （ A） Going to church. （ B） Going to work in the office. （ C） Staying at home. （ D） Going to a party.

37、34 Who brought the Frenchmens neckwear to Britain? （ A） Tony Blair. （ B） Charles . （ C） Jim Callaghan. （ D） Andrew Turnbull. 35 When did British gentlemen begin to wear ties regularly? （ A） After the late 19th century. （ B） In the 1630s. （ C） In 1660. （ D） In the late 18th century. 36 Where Have All

38、 the Frogs Gone? In the 1980s, scientists around the world began to notice something strange: Frogs were disappearing. More recent research has shown that many kinds of amphibians (两栖动物 ) are declining or have become extinct. They have been around for a long time - over 350 million years. Why are th

39、ey dying out now? Scientists are seriously concerned about this question. First of all, amphibians are an important source of scientific and medical knowledge. By studying amphibians, scientists have learned about new substances that could be very useful for treating human diseases. Further research

40、 could lead to many more discoveries, but that will be impossible if the amphibians disappear. The most serious aspect of amphibian loss, however, goes beyond the amphibians themselves. Scientists are beginning to think about what amphibian decline means for the planet as a whole. If the earth is be

41、coming unlivable for amphibians, is it also becoming unlivable for other kinds of animals and human, beings as well? Scientists now believe that amphibian decline is due to several environmental factors. One of these factors is the destruction of habitat, the natural area where an animal lives. Amph

42、ibians are very sensitive to changes in their habitat. If they cannot find the right conditions, they will not lay their eggs. These days, as wild areas are covered with houses, roads, farms, or factories, many kinds of amphibians are no longer laying eggs. For example, the arroyo toad (蟾蜍 ) of sout

43、hern California will only lay its eggs on the sandy bottom of a slow-moving stream. There are very few streams left in southern California, and those streams are often muddy because of building projects. Not surprisingly, the arroyo toad is now in danger of extinction. There are a number of other fa

44、ctors in amphibian decline. Pollution is one of them. In many industrial areas, air pollution has poisoned the rain, which then falls on ponds and kills the frogs and toads that live there. In farming areas, the heavy use of chemicals on crops has also killed off amphibians. Another factor is that a

45、ir pollution has led to increased levels of ultraviolet (UV) light. This endangers amphibians, which seem to be especially sensitive to UV light. And finally, scientists have discovered a new disease that seems to be killing many species of amphibians in different parts of the world. All these reaso

46、ns for the disappearance of amphibians are also good reasons for more general concern. The destruction of land, the pollution of the air and the water, the changes in our atmosphere, the spread of diseases - these factors affect human beings, too. Amphibians are especially sensitive to environmental

47、 change. Perhaps they are like the canary (金丝雀 ) bird that coal miners once used to take down into the mines to detect poisonous gases. When the canary became iii or died, the miners knew that dangerous gases were near and their own lives were in danger. 36 Losing amphibians means losing （ A） knowle

48、dge about fatal human diseases. （ B） knowledge about air and water pollution. （ C） a chance to discover new medicines. （ D） an opportunity to detect poisonous gases. 37 Amphibians lay their eggs （ A） in any stream they can find. （ B） in places without UV light. （ C） only on sand. （ D） only in the ri

49、ght conditions. 38 The arroyo toad is disappearing because （ A） it has been threatened by frogs. （ B） it is losing its habitat. （ C） a disease has been killing its eggs. （ D） it cant bear the cold of winter, 39 Coal miners once used the canary bird to detect （ A） poisonous gases. （ B） air pollution. （ C） water leakage. （ D） radiation. 40 Scientists think that the decline of amphibians could （ A） cause environmental change. （ B） cause a decline in other kinds of animals. （ C） be a warning signal for hu
