1、选A---saw是see的过去式, see的结构是: see sb/ sth. doing sth.看见正在做某事,
或: see sb./sth. do sth. 看见做过了某事,所以在: A, B中选择. B不符合题意
翻译: 当他看见飞机起飞时,他想起了他的最初的梦想
2、C---listen是指有意识地去听,比如听课,听音乐等。hear是指听到。hear from是“收到。。。信",hear about是“听说某事”,所以C最合适----当她听说了这个可怕的消息,她觉得非常害怕。
3、C---首先要排除D,因为没有be动词,不能直接用enjoying.其次,从句when the alien landed.特指了一个时间点,外星人着陆的时候,所以用过去进行时最生动----当外星人着陆的时候,孩子们正在操场上玩得很高兴。(之所以不选B,是因为其中少了一个a--have a good time)
