高中非谓语,详细全面最好

非谓语一高考需掌握的相关知识点：

另外，常见的还有：

1、情态动词（除ought 外）后的to已省略。

例：You must go to the hospital first. 你必须先去医院。

I can swim well. 我能游得很好。

2、使役动词let, have, make后，感官动词see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等词后的to省略。

例：He made the baby crying all night long. 他让那个婴儿哭了一整夜。Let it be. 就这样吧。when I passed by, I saw the girl picking the flowers. 我经过的时候，看见那个女孩在摘花。

注意：在这些词的用法中，用于被动语态时不能省去to。

例：I saw him dance. 我看见他跳舞。=He was seen to dance.

The boss made them work the whole night. 老板让他们整夜干活。

=They were made to work the whole night.

3、would rather/had better/ had best后的to省略。

例：I would rather go to Japan than the USA.我宁愿去日本也不想去美国。

You had better take a hat with you.你最好带上一顶帽子。

4、why…/why not…句型中not后to省略。例：why not come to my home for a dinner tonight? 今晚何不来我家吃顿饭。

5、help 后可带to，也可不带to, help sb （to）do sth：

6、如果在feel，know，observe，see后面跟的不定式是be，则to不可省略。例：We all felt that to be the highest praise．

We know him to be brave．

The only thing that I have observed to be without limit is the businessman's desire for profits．

Now I saw him to be the man who walked up the hill every morning．

应该注意到的是feel和see这两个动词在上述例句中已不是感觉动词，它们的意思分别是“认为”、“以为”和“知悉”、“了解”。

7、由and, or和than连接的两个不定式，第二个to 可以省去：例：He forgot to go to her home and give her the important letter. 他忘了去她家并把一封重要的信件给她。

8、通常在discover, imagine, suppose, think等词后作宾补时，可以省去to be。例：He is supposed （to be）nice. 他应该是个好人。

9、but作介词，后结不定式结构时，前面谓语动词部分若含有do的形式时，but 后的不定式要省去to,否则要带to.

例he wants to do nothing but go out.

He wants to believe anything but to take the medicine.

10、不定式做表语时，一般要带to,但若主语部分中含有do的各种形式时，符号to可省去。

例we’ve missed the last bus. All we could do now is walk home.

It（This, That）＋be＋a／an＋adj. ＋ n. ＋to do

在这种句型中, 不定式与前面的名词有动宾关系。动词不定式可改为动词不定式复合结构。

例如: This is a difficult question to answer. 这是个难答的问题。

question与to answer为动宾关系。to answer可改为 for me to answer。

再如: It is an easy sentence to translate. 这个句子很容易翻译。
