动词不定式做补语 定语
动词不定式做补语定语一、动词不定式做补语1. 概念- 在英语中，动词不定式做补语用来补充说明宾语或主语的情况。
- 例如：We want you to come.（在这个句子中，“you to come”是宾语补足语，“to come”补充说明“you”的动作，表明我们想要你做的事情是“来”。
）2. 宾语补足语的情况- 使役动词后的宾补- 使役动词如make，let，have等，其中make和let后的不定式做宾补时要省略to，但在被动语态中要加上to。
- 例如：He made me laugh.（主动语态，“laugh”是不带to的不定式做宾补）- I was made to laugh by him.（被动语态，“to laugh”做主语补足语，这里要加上to）- have既可以用不带to的不定式做宾补（表示让某人做某事的一次性动作），也可以用现在分词做宾补（表示让某人一直处于做某事的状态）。
- 例如：I had him clean my room.（让他打扫我的房间，一次性动作） - I had him waiting outside for an hour.（让他一直在外面等了一个小时）- 感官动词后的宾补- 感官动词see，hear，watch，notice，feel等，其后可以接不带to的不定式做宾补，表示动作的全过程；也可以接现在分词做宾补，表示动作正在进行。
- 例如：I saw him cross the road.（看到他过马路的全过程）- I saw him crossing the road.（看到他正在过马路）3. 主语补足语的情况- 在被动语态中，原来的宾语补足语就变成了主语补足语。
- 例如：He was seen to enter the building.（主动语态是“Somebody saw him enter the building”，在被动语态中，“to enter the building”就成了主语补足语）二、动词不定式做定语1. 概念- 动词不定式做定语用来修饰名词或代词，一般放在被修饰词之后，表示将要发生的动作或者目的等。
