动词不定式讲与练
含义
1. 由“to＋动词原形”构成，是非谓语动词的一种。
2. 在句子中不能单独作谓语，也没有人称和数的变化，其否定结构是“not+to＋动词原形”
3. 在句子中可以作主语、宾语、目的状语、宾语补足语等。
备注：
动词不定式是一种非谓语动词形式，由"to+动词原形"构成，其中to不是介词，而是动词不定式的符号。
动词不定式有两种形式：
一是带to的动词不定式，即"to+动词原形"；
二是省略to的不定式，即"动词原形"。动词不定式没有人称和数的变化，其否定形式为"not+to+动词原形"或"not+动词原形".
二、分类
（一）动词不定式作主语
1.动词不定式做主语一般放在句首，谓语动词用第三人称单数。
2.It+be动词+adj+(for sb)+to do sth “对......来说, 做某事很......”
常用it做形式主语,将to do放在后面,避免句子“头重脚轻”。
（二）动词不定式作宾语
1.用于动词后面的不定式，充当宾语成分
2.常见的跟动词不定式做宾语的动词有：
ask, decide, hope, want, agree, choose, wish , manage , pretend, expect , demand, plan, prepare, promise, offer, afford,arrange,learn,refuse等
常跟动词不定式作宾语动词歌谣：
三个希望两答应；(hope/wish/ want,agree/ promise)
两个要求莫拒绝；(demand/ask;refuse)
设法学会做决定；(manage;learn;decide)
不要假装在选择。(pretend;choose)
sb. + feel/find/make/think/believe + it + adj. + to do sth.
动词不定式作宾补
用来补充说明宾语的动作、状态或身份，让句子的意思更完整
结构为：动词+ sb. + to do sth
常见带to的不定式(to do)作宾语补足语
Ask，tell，order，want，wish，expect，like， hate，advise，encourage等
注意：使役动词和感官动词后接不定式作宾补时，主动语态中省略to，被动语态中还原to
使役动词：make, let, have
感官动词：see, watch, hear, notice, feel, observe
（动词+sb+do sth)
动词不定式作目的状语
用于说明某一动作或状态的目的，原因或意图，意为“为了……”“以便……”
通常位于句尾，但也可置于句首(强调目的)，用逗号隔开。
