Question

根據(jù)短文內(nèi)容，用方框中所給單詞的適當形式填空，每詞限用一次。

Scientists would like to put a huge mirror in space above the earth. It might be sixty miles wide. It would be   【小題1】 to catch the rays of the sun. it would direct the sun’s rays on the earth as a child might do to make sunlight   【小題2】 on the wall with a hand mirror.
Why do they want to do this? The sun’s rays could be   【小題3】  in many ways. They could light up   【小題4】  by night. The warm rays could stop frosts(霜凍) which might come at night and hurt fruit and crops. They could melt（融化)【小題5】 icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.

Answer 1

【小題1】used         
【小題2】dance 
【小題3】helpful
【小題4】cities
【小題5】dangerous

解析試題分析：
【小題1】根據(jù)句意：它將被用來追趕太陽光，可知填寫used ，be used to do sth被用來做某事。
【小題2】make sb do sth讓某人做某事，前面已使用了動詞use，只剩下一個動詞dance，所以填寫dance。
【小題3】be helpful有幫助，，故填寫helpful。
【小題4】根據(jù)句意：他們會在夜晚照亮城市，可知填寫cities。
【小題5】只剩下一詞danger，用于修飾后面的名詞icebergs ，所以用形容詞形式dangerous。
考點：選詞填空。
