不定式修饰的是整个谓语动作，说明“为什么做”。
不定式跟在宾语后面，说明“宾语做什么”。
　动词不定式是非谓语动词的一种形式，基本形式是“t+动词原形”。其中t是动词不定式符号，在有些情况下可以省略。动词不定式的否定形式为“nt t+动词原形”。

Please tell Jim nt t cme late next time.　请告诉吉姆下次别迟到了。
1、动词不定式作状语 动词不定式可以在句中作状语，表示目的、结果或原因。作目的状语时通常放在句末，用于正式语境或需要强调时，也可以放在句首，用逗号与后面的句子隔开。

He is t yung t lk after himself.他年龄太小，不能照顾自己。
T prtect the envirnment, we shuld reduce plastic use.　为了保护环境，我们应该减少塑料的使用。
2、动词不定式作宾语补足语宾语补足语是紧跟在宾语之后，对宾语的身份、状态或动作进行补充说明的成分，使宾语的意义更加完整。此时可以是带t的不定式，也可以是不带t的不定式，这主要取决于谓语动词。
①接带t的动词不定式作宾语补足语的动词(短语)有：tell、ask、rder、allw、encurage、advise, want, wish, expect 、invite, chse，wuld like等。

Then he asked me t sit dwn beside a girl.　然后他让我坐在一个女孩旁边。
