huge mirror高中英语阅读理解
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.
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.
