2011年6月大学英语四级听力真题MP3下载(含文本)

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。

39. discovered
解析：空缺部分作后置定语，从音频可知是发现(discovered)，用其过去完成时态。

40. scientific
解析：该空后接名词，应为形容词，scientific。

41. motion
解析：
原文描述，实验已证明运动加快会使宇航员的时间延长。这里的运动为motion。

42. predicted
解析：爱因斯坦在1905年时作出预测，用过去时predicted。

43. introduced
解析：这是爱因斯坦提出的一个相对时间的概念，用过去时introduced。

44. that move at a speed greater than light, and therefore, might serve as our passports to the past.
解析：当下进行的研究旨在证实，是否有这样的物质，即能以超光速运行，并可以作为我们回归过去的“通行证”。填句只需意思相近就可以，关键抓住核心：超光速运行，可帮助人类回到过去。

45. seems to have been a part of humanity for as long as human have existed.
解析：人类对时间的节约，获取，浪费以及流失等的着迷，自人类诞生以来就一直是其生活的一部分。核心：人类诞生以来就一直存在的，如影随形的。

46. used a definition of time for experimental purposes, as that which is measured by a clock.
解析：人类也对时间的含义非常着迷，爱因斯坦就曾提出一个试验性的定义，这个定义下的时间可以用钟表来测量。核心意思：试验性的定义，可以用钟表来测量。

解题密钥：
听类似文章时首先要注意把握逻辑结构，也即听第一遍听时把握大意，先不要急于填写所有空缺，重点是要缕清思路，听懂文章在说什么，记录关键信息词；有了对文章整体的把握后，第二遍听时就容易许多，这时就可以把空缺进量补齐，注意填句部分不一定非得按原文填写，只要意思相近就行；第三遍是最后一遍，此时要边听边检查已填写空缺，另外也可补填遗漏。

听力音频结束后，可对所填词汇进行检查，此时主要根据语法知识保证词形，词性准确无误；另外也可重新组织语句，完善填句部分。
