重点语法 动词不定式
(时间:40分钟,满分:100分)
在中考语法项目中,主要考查动词不定式作宾语、宾语补足语、目的状语。动词不定式由“to+动词原形” 构成,有时to省略,直接由动词原形构成。否定式由“not to+动词原形” 构成。
如:We decided to go on hiking though we were tired. 虽然我们很累,但是我们决定继续远足。
The girl tried not to wake up her mother. 这女孩尽量不吵醒她妈妈。

用法
例句
作主语
谓语动词用单数形式,为避免"头重脚轻"常用it作形式主语。常用句型有:
①It is +adj.+for/of sb.+(not)to do sth.意为"做某事对某人来说是……"。
②It takes sb.+some time+to do sth.意为"做某事花费某人多长时间"
To master a language is not easy=It is not easy to master a language.学好一门语言是不容易的。
作宾语
常接动词不定式作宾语的动词有:would like, want, like,hope, wish, plan,decide,learn, agree, try, remember, forget, expect, refuse,afford, prefer, continue, promise, begin, start 等think,find,believe等动词可用于"动词+it+adj.+to do sth."句型中。it作形式宾语,而真正的宾语是后面的不定式。
I would like to make friends with you.我想要和你交朋友。
I find it difficult to pass my math exam.我发现要通过数学考试很难。
作定语
动词不定式放在名词、代词后作定语,两者之间常有逻辑上的动宾关系,因此,如果不定式中的动词是不及物动词,后面应该加上相应的介词。常接不定式作定语的名词有:time, need, way, chance, opportunity, courage, reason, effort, determination, decision ,ability, ambition
Can you give me a pen to write with?能给我一只用于书写的笔吗?
Do you have something to say?你有什么要说的吗?
作状语
不定式常可用作状语,修饰动词,表示行为的目的、结果和原因。
To do a good job,we must have the right tools. 要干好活工具要对头。
作表语
放在系动词后作表语。
My dream is to be an engineer.我想成为一名工程师。
有些及物动词,接不定式作宾语补足语时(动词+sb.+do ),要省略to。这类及物动词常见的有:
let 让 make 使 have 使
see 看见 watch 注视 hear 听到
notice 注意到 feel 感觉起来
被动语态中要还原to,如 make sb. do被动语态变为 sb. be made to do。
如:I saw him read in the library yesterday. 我昨天看到他在图书馆阅读
