问答题
Practice 1  No one knows what time itself is. We cannot see it. We cannot touch it. We cannot hear it. We know it only by the way we mark its passing. For all our success in measuring the tiniest parts of time, time remains one of the great mysteries of the universe.  One way of thinking about time is to imagine a world without time. There could be no movement, because time and movement cannot be separated. A world without time could exist only as long as there were no changes. For time and change are linked. When something changes, you know time has passed.

正确答案:
【参考译文】
时间本身究竟是什么,没有人知道。时间是看不见、摸不着、也听不到的。我们标出时间的消逝,通过这种方式,我们才知道了时间。尽管我们能成功地测定出极其短暂的一段时间,但是对我们来说,时间仍然是宇宙间最大的奥秘之一。
思索时间的一种方式是设想一个没有时间的世界。在这个世界里也不会有运动,因为时间和运动是分不开的。没有时间的世界只能在没有任何变化的条件下存在,因为时间和变化是联系在一起的。当事物发生了变化,时间也就消逝了。
