M: Jane, suppose you lost all your money while taking a vacation overseas, what would you do?

W: Well, I guess I'd sell my watch or computer or do some odd jobs till I could afford a return plane ticket.

Q: What are the speakers talking about?

答案:B. An imaginary situation.

解析:根据原文录音可知,对话开头男生讲到:“Jane, suppose you lost all your money while taking a vacation overseas, what would you do? ”这里的"suppose"表明“假定、料想”由此可见,两人谈论的是一个虚拟场景。

Section B

Passage One

There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes.

We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight.

Another myth about eyes is that they can be replaced, or transferred from one person to another. There are close to one million nerve fibres that connect the eyeball to the brain, as of yet it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible.

Questions 26 to 28 are based on the passage you have just heard.

26. What does the speaker want to tell us about eyesight?

27. What do studies about wearing the wrong glasses show?

28. What do we learn about eye transplanting from the talk?

Section C Compound Dictation

Contrary to the old warning that time waits for no one, time slows down when you are on the move. It also slows down more as you move faster, which means astronauts some day may survive so long in space that they would return to an earth of the distant future。

If you could move at the speed of light, your time would stand still, if you could move faster than light, your time would move backward. Although no form of matter yet discovered, moves as fast as or faster than light, scientific experiments has already confirmed that accelerated motion causes a traveler’s time to be stretched. Albert Einstein predicted this in 1905, when he introduced the concept of relative time as part of his special theory of relativity. A search is now under way to confirm the suspected existence of particles of matter that move at a speed greater than light. And therefore, might serve as our passports to the past. An obsession with time, saving, gaming, wasting, losing and mastering it, seems to have been a part of humanity for as long as human have existed. Humanity also has been obsessed with trying to capture the meaning of time. Einstein used a definition of time for experimental purposes, as that which is measured by a clock. Thus time and time’s relativity are measurable by any hour glass, alarm clock, or atomic clock that can measure a billionth of a second。

36. survive 37. distant 38. backward 39. discovered 40. scientific 41. motion 42. predicted 43. introduced 44. that move at a speed greater than light, and therefore, might serve as our passports to the past. 45. seems to have been a part of humanity for as long as human have existed. 46. used a definition of time for experimental purposes, as that which is measured by a clock。
