今天做练习题的时候看到一个完形填空:
after __1___(hear)that,she said sorry and helped him ____2___(look)for his watch , at last they found it under a chair.
我1写的是heard,2是looking
答案是1 hearing, 2 look
我有点不明白了,想表达“听完以后”用after+Ved不对吗?
还有后半句的帮他找手表,不应该用helped him looking for his watch吗?为什么是look呢?用动词原型的话,前面也有个help动词,不就变成两个谓语动词了么,这里为啥用look原型
求分析
【答】1. 这里的 after 只能说介词,后面接动名词。 2. said 和 helped 是并列的谓语动词。在 ”help + 宾语”后面可以接动词不定式作宾语补足语(有无 to 均可),不能接动词的 -ing 形式。
