Read and summarise 新课讲授 动词不定式 当句子中已经有谓语动词，而我们又要表达不止一个动作概念时，其余的动词可以使用非谓语形式。动词不定式是动词的一种非谓语形式，其基本形式是“to+动词原形”。 e.g. He wants to play football after class. 他想课后踢足球。 动词不定式在句子中不充当谓语，因此没有人称、数的变化，可在句中充当多种成分，如主语、宾语、宾语补足语、状语等。 e.g. To learn English well is not easy. 学好英语不容易。 What are you trying to do 你想干什么？ The teacher asked us to read more English stories. 老师让我们多读英语故事。 They got up early to catch the early bus. 他们早起去赶早班车。 动词不定式做宾语 动词不定式在句中常充当谓语动词的宾语，这一类谓语动词常见的有：afford、agree、choose、decide、forget、hope、learn、manage、plan、prepare、promise、refuse、try、want。 e.g. I decided to visit my grandparents this weekend. 我决定这个周末去看望祖父母。 注意：动词不定式的否定形式是“not to+动词原形”。 e.g. You must promise not to do this again. 你必须保证不再这么做了。 1.
