　　Passage Three

　　Since a union representative visited our company to inform us about our rights and protections. My coworkers have been worrying about health conditions and complaining about safety hazards in the workplace. Several of the employees in the computer department, for example, claim to be developing vision problems from having to stare at a video display terminal for about 7 hours a day. The supervisor of the laboratory is beginning to get headaches and dizzy spells because she says it’s dangerous to breathe some of the chemical smoke there. An X-rays technician is refusing to do her job until the firm agrees to replace its out-dated equipment. She insists that it’s exposing workers to unnecessarily high doses of radiation. She thinks that she may have to contact the Occupational Safety and Health Administration and asked that government agency to inspect the department. I’ve heard that at a factory in the area two pregnant women who were working with paint requested a transfer to a safer department, because they wanted to prevent damage to their unborn babies. The supervisor of personnel refused the request. In another firm the workers were constantly complaining about the malfunctioning heating system, but the owners was too busy or too mean to do anything about it. Finally, they all met an agree to wear ski-clothing to work the next day. The owner was too embarrassed to talk to his employees. But he had the heating system replaced right away。

　　解析：细节题。作者有直接读出答案，比较简单。

　　34 What does the speaker say about the two pregnant women working with paint?

　　A) They requested to transfer to a safer department。

　　答案：A) They requested to transfer to a safer department。

　　35 Why did the workers in the firm wear ski-clothing to work?

　　C)To protest(微博) against the poor working conditions。

　　答案：C)To protest against the poor working conditions。

　　解析：推理题。本题容易误选D选项。因为是heating system出了故障。但通过下文"too embarrassed""had the heating system replaced right away" 从老板的反应及采取的措施可以推断出，员工们穿滑雪服地原因其实为对差的工作环境向老板提出抗议。

　　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(宇航员) 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, gaining, 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。

　　本文提要：

　　本篇属于科技类文章，主要围绕时间和运动的关系展开；用谚语开篇引出全文，很有吸引力。中间引用爱因斯坦的相对论相关概念，具体阐述主题。

　　答案：

　　36. survive

　　解析：文章描述：运动越快，时间变慢得也更快，这也就意味着宇航员有朝一日可以在太空中生存(survive)很久，如此一来他们就可以在遥远(distant)的未来重返地球。

　　37. distant

　　解析：这个空在future 前面，所以预判该填形容词常用搭配无非near，close， distant等 ，根据听力原文，如上所述，确定是遥远的未来；填distant。

　　38. backward

　　解析：速度达到光速，时间静止；根据常识推断，若速度快于光速，那么时间将后退，即move backward，根据听力原文可确定这一推断。
