初中英语 人教版八年级上册Unit 5 语法专项-动词不定式+配套练习(含答案)
动词不定式动词不定式由“to ＋动词原形”构成，有时可以省略to。
动词不定式在句中可作宾语、宾语补足语、状语、定语等。
动词不定式在句子中不作谓语，所以没有人称、数和时态的变化，其否定式是在to前加上not。
如：ask sb. not to do；tell sb. not to do；具体用法见下表：1)不定式结构作主语如果不定式较长，显得头重脚轻，则可由代词it作形式主语(形式主语it不可由that或this等其他代词代替)，而将不定式放到后面。
不定式结构所表示的动作是谁做的，即不定式的逻辑主语，通常可以通过It is + adj. + for sb. to do sth.在某些形容词(如careless，clever，considerate，foolish，good，impolite，kind，naughty，nice，silly，stupid等)作表语时，不定式后可以加of来引导出其逻辑主语It is + adj. + of sb. to do sth.2)不定式作宾语不定式作宾语有两种：一种是及物动词后直接跟带to的不定式，另一种是“及物动词+疑问词+带to的不定式。
及物动词+带to的不定式结构:只能跟动词不定式的动词，常见的有: afford，agree，aim，appear，ask，believe，care，claim，decide demand，desire，determine，expect，fail，happen，hesitate，hope，intend，learn，long，manage，offer，pretend，promise，prepare，refuse，seek，swear，undertake，want，wish等。
口诀：同意提出做计划,要求答应来帮忙。
准备决定遭拒绝,敢于选择有希望。
不能做到莫假装,设法做成决心坚。
3)不定式做表语一种情况为主语是不定式(表示条件)；表语也是不定式(表示结果)：To see is to believe.另一种情况为主语是以aim，duty，hope，idea，job，plan，problem，purpose，thing，wish等名词为中心的短语，或以what引导的名词性从句，不定式表语对主语起补充说明作用：4)不定式作定语不定式结构作名词词组修饰语主要有三种类型：第一种，被修饰的名词词组是不定式的逻辑宾语。
