Answer 1

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

解析试题分析：
【小题1】根据句意：它将被用来追赶太阳光，可知填写used ，be used to do sth被用来做某事。
【小题2】make sb do sth让某人做某事，前面已使用了动词use，只剩下一个动词dance，所以填写dance。
【小题3】be helpful有帮助，，故填写helpful。
【小题4】根据句意：他们会在夜晚照亮城市，可知填写cities。
【小题5】只剩下一词danger，用于修饰后面的名词icebergs ，所以用形容词形式dangerous。
考点：选词填空。
