2020天津解放军考军校招聘考试-语法部分（三十七）

⑦ 动词不定式可以在句子中用作表语,限用于连系动词之后。如：My job is to keep the goal.(我的工作就是守住球门)

⑧ 动词不定式可以在句子中用作复合宾语中的宾语补足语。

如：Mum asked me to help her with the cooking.(妈妈叫我帮助她做饭)/ I would like you to see my parents.(我想要你见见我的父母)/ The boss often made the workers work 14 hours a day.(老板常让工人们一天工作14小时)/ Now let me hear you play the violin.(现在让我来听你拉小提琴)

[注意] help之后做宾补的不定式符号to可以省略;hear / see / feel / watch之后的宾补用不定式与现在分词时,含义不同,需特别注意,(参见现在分词部分)。试比较：

I heard her crying when I walked past.(我路过时听到她正在哭)(指当时瞬间的情况)

I sat near her and heard her sing the new song.(我坐在她附近听她唱新歌)(指整个过程)
