时间之谜
如果你能够看懂时钟，你就可以知道一天的时间。但是谁也不知道，时间本身究竟是什么。时间是看不到、摸不着、听不见的，我们只能记录时间消逝的办法才知道时间的存在。虽然我们成功的测量了时间的分分秒秒，但时间仍然是宇宙间及其神秘的现象之一。
思考时间的一个方法是设想一个没有时间的世界。那样，就不可能有运动了，因为时间和运动是不可分开的。一个没有时间的世界只有在没有变化的情况下才能存在。因为时间和变化是联系在一起的。当某件事发生变化时，你知道时间已经流逝。在现实世界里，变化是永无止境的，有一些变化，如月食，只发生在瞬间，而另一些变化则反复出现，比如日出和日落。人们一直注意那些反复出现的自然现象，在人们开始计算这些现象时，他们就开始测定时间了。

MYSTERY OF TIME
If you can read a clock, you can know the time of day. But 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. Then 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. In the real world, changes never stop. Some changes happen only once in a while, like an eclipse of the moon. Others happen repeatedly, like the rising and setting of the sun. People have always noted natural events that repeat themselves. When people began to count such events, they began to measure time.
