中考专项讲解及实战不定式练习
不定式
不定式和动词象一对姐妹一样亲密,本不该拆开来讲,可是篇幅有限,只能让他们分开了。不定式的构成非常简单,告诉我是什么?对!是to+动词原形。当然啦,to有时也可以不带。动词不定式没有人称和数的变化,可以担当除谓语外的任何句子成分。那什么时候可以不带to呢? Listen to me carefully.
不定式省to有四种情况:
使役动词 let,have,make 等后接不定式。如:Let him go! 让他走!
would rather,had better后。如:You had better stay at home.你最好呆在家里。
Why... / why not...后。如:Why not have a good rest on Sunday? 为什么星期天不好好休息一下呢?
感官动词 see, watch, look at, hear, listen to, smell,feel, find 等后作宾补,省to。如:I saw him dance. 我看见他跳舞。
注意:这些情况在被动句中可千万不可省to 哟! 如:The boss made them work the whole night. 变成被动句:They were made to work the whole night.

不定式的特殊用法:
It与不定式:动词不定式可以做主语,但如果动词不定式太长,显得头重脚轻的,那么我们就可用形式主语it代替,而把真正主语(即不定式)放于句尾。
如: It is not difficult for me to study English well.(对我来说学好英语是可能的。)
不定式还可以充当句子的宾语,但有些动词,如find,think,believe 等,在语法上不能接受不定式作宾语,只有用it作形式宾语,从而把动词不定式置于句尾。这样的不定式可继续充当其宾语的作用。
如: I found it difficult to fall asleep.我发现很难入睡。
还有一点:动词不定式,还可用在how,when,where,what,which 等疑问代词或副词之后,与其共同作宾语。如:I don't know how to use a computer.我不知道怎样使用电脑。Remember?
too...to...和enough...to:too...to表达"太 ... 一致于不能..."。
enough ... to 表达 "足以..."。这两个词组的用法用两个例子就可以说清楚了。
The box is too heavy for me to lift.这个箱子太沉了,我提不动。
He is old enough to go to school.他到上学的年龄了。也就是说,他的年龄足够上学了。记住这两个句子就可以举一反三,应用自如。你记住了吗?
