Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays (光线) of the sun. It would direct the sun’s rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror.

　　科学家们想把一个巨大的镜子在地球上空的太空。也许是六十英里宽。它可以用来捕捉光线(光线)的太阳。这将直接的太阳光线在地象一个孩子可能会做一个手拿镜子让阳光在墙上舞蹈。

　　Why do they want to do this? The sun’s rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts(霜冻) which might come at might and fruit crops. They could melt (融化) dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.

　　他们为什么要这么做?太阳的光线在许多方面可能是有帮助的。他们可以照亮城市的夜晚。温暖的光线能阻止霜冻(霜冻)可能在可能和果树。他们会融化(融化)在海洋中危险的冰山。也许他们会改变云的运动和带雨在需要它的地方。
