专题06 非谓语动词
初中英语非谓语动词形式主要包括动词不定式,现在分词,过去分词,以及动名词。主要考查动词不定式表目的,表将来;动名词做主语及宾语用法;现在分词表进行,表将来,过去分词表完成,表被动等。其考查重点为:
1. it作形式主语、宾语的用法
2. 感官动词后不定式作宾语补足语和动词ing形式作宾语补足语的用法:
3. 动词不定式与疑问代词和疑问副词的连用
4. 一些特殊动词的动词不定式作宾语补足语时不带口,但变为被动语态时就要带to:
5. 有些动词既可接不定式也可接动词ing形式作宽语,但表达的意思不同。
知识点1:不定式重难点
1.“一感一听三看两让”变被动语态时,动词不定式符号to要还原:feel/hear/
see/watch/notice/have/make sb.do sth.→be felt/heard/seen/watched/noticed/had/made to do sth.
2.remember/forget/regret to do sth.记得/忘记/后悔去做某事
remember/forget/regret doing sth.记得/忘记/后悔做了某事
3.stop to do sth.停下来去做某事
stop doing sth.停止做某事
4.see/hear sb.doing sth.看见/听见某人正在做某事
see/hear sb.do sth.看见/听见某人做了某事或常做某事
5.常考的省略了to的动词不定式的句型:
Why not do sth.?/Could(Would) you please (not) do sth.?/had better (not) do sth./would rather do...than do
6.there be+主语+to do sth.
There is nothing to worry about.
7. “疑问词+不定式”结构:
疑问词who, what, when, where, how, which等后接不定式,构成不定式短语,在句中作主语,宾语,表语等。
Where to live is a problem. (主语)
Do you know when to start? (宾语)
The problem is how to use the machine. (表语)
I don’t know ________ to do it. (宾语) A.what B. how

It’s+adj.+(of sb.) to do sth.

It’s best for sb. to do sth对某人来说做某事是最好的
It’s time for sb to do sth.是某人做某事的时候了
too…(for sb.)to ......太.....以致不能.....=not…enough to do=so...that....(否定)
the first/last/next/only/second to do sth.
He is the only person to know the truth.

知识点2:动名词重难点
后跟doing 的常考短语:
have difficulty/trouble/problems doing
feel like doing=would like to do
spend time (in) doing be busy doing
prefer doing to doing be used to doing
look forward to doing devote to doing
make a contribution to doing
知识点3:分词重难点
现在分词与动名词的构成形式一样,也是由动词原形后加词尾-ing 构成。现在分词的形式:v-ing否定形式:not+ v-ing
①作表语 The problem is puzzling.
②作定语 A little child learning to walk often falls.
