赘婿结局是怎样的
一、动词不定式的用法（重点）
1、结构及特征：动词不定式的基本形式是“to + 动词原形”，有时可以不带to。动词不定式没有人称和数的变化，在句子中不能作谓语，但可以担任除谓语外的任何成分——主语、表语、宾语、状语和宾语补足语，所以我们又称之为非谓语形式。动词不定式仍保留动词的特点，即它可以有自己的宾语和状语。
不定式的语态
主动语态 被动语态
一般式 to do to be done
完成式 to have done to have been done
进行式 to be doing
不定式时态
完成 I am sorry to have made so many mistakes.(动作发生在谓语动词表示的动词前)
进行 He seems to be eating something.(表示动作正在进行，与谓语动词表示的动作同时发生)
2、动词不定式的用法：动词不定式具有名词、形容词和副词的特征，在句子中可以作主语、表语、宾语、定语和状语。
1） 作主语
例如：To learn English well is not easy. 或 It is not easy to learn English well.
[说明]动词不定式作主语时，往往用it作形式主语，这种句型可归纳为下面的句型：
It is + adj.+ for sb. to do sth. 当形容词表示事物的特征，特点或客观形式，常见
的形容词有easy, hard, interesting
It is hard for him to study two languages.
It is + adj + of sb to do sth 形容词表示性格，品德或表示主观感情 good nice kind clever
It is very nice of you to help me.
2）作表语 My wish is to become a teacher. be动词之后，形成表语，常用来表示预定要发生的动作，也可用来表示未来的可能性和假设
3）作宾语 只可用不定式作宾语的动词 ask hope help promise learn
Do you hope to go fishing with me?
既可接不定式也可以接动名词 remember forget like need stop try start begin permit love/ go on /
I stop to run. 我停下来开始跑
I stop running. 我停下来不跑了。
it 作形式宾语 Do you think it better to say it in this way?
4）作宾语补足语 1) 不定式作宾补 ask teach allow invite tell want prefer order get feel hear think see expect encourage
The teacher told him not to be late next time.
2)使役动词省略to let make havesee you again翻译
She had the students work out the problem.
3) Could you help me (to) close the window?
5）作定语 I have a lot of work to do. 表示未发生的动作
Can you bring me a chair to sit?
马的故事 He needs someone to help him with his work.
6）作状语 He stopped to have a look.
[说明] 动词不定式的否定形式：not + to + 动词原形构成
例如：He asked me not to make such a mistake.
3、不定式的否定形式： Tell him not to shut the window…
4、动词不定式与疑问词连用：疑问词who, what, which和疑问副词when, where, how,
why等后面可以按动词不定式，构成动词不定式短语，可以在句子中作主语、宾语、表语等成分。
例如：(1) He doesn’t know how to use the machine. (不定式作宾语)
唐宁老公 (2) How to use the machine is a question. (不定式作主语)
(3) The question is when to go there. (不定式作表语)
5、省to 的动词不定式
1）使役动词 let, have, make：
2）感官动词 see, watch, look at, notice, hear, listen to, smell, feel, find 等后作宾补，省略to。
注意：在被动语态中则to 不能省掉。
A. I saw him dance. =He was seen to dance.
B. The boss made them work the whole night.
=They were made to work the whole night.
3）would rather，had better + do , would you please, rather than
【难点】
6、不定式的特殊句型：
1）too…to…：太…而不能…
so/such +adj/adv +as to +v (表结果)
His father was so angry as to be unable to speak.
He is too excited to speak.
2）enough to do：足以做 …
The child is old enough to go to schooll.
3）Why not +动词原形"表达向某人提出建议，翻译为："为什么不……?"
Why not take a holiday?
4）so as (not) to do: in order to do only to do to do （表示目的）
David came to China to study Chinese.
Go in quietly so as not to wake the baby.
5)用作介词的“to”：look forward to 渴望; pay attention to 注意; devote oneself to 献身于；be/get used to 习惯等等。
动名词的用法
二、动词的-ing形式：
形式 主动式 被动式
一般式 doing being done
完成式 having done having been done
一般时态 Do you mind my smoking here? (动作发生在谓语动词表示的动作之后或者两个动作同时发生)
完成时态 I regret not having 演员 白静studied hard.(动作发生在谓语动词表示的动作之前)
2. 在下面两种句型中，只能用动名词
There + be + no + 动名词
There is no gettingqq改密码网站 along with him.
It is +no use/good/ fun/nice + 动名词
It is no use learning English without speaking.
3.只可以接动名词的动词或者动词短语
dislike admit enjoy deny mind miss risk finish avoid consider excuse suggest practice be worth keep on can not help give up put off leave off lead to
3．比较：
1）共同点：动词不定式结构和动词的-ing形式都被称之为非谓语结构，因此它们一般都可以放在句中除了谓语之外的其他位置。
2）区别
①动词不定式的基本含义是表示谓语动词后面的动作还未发生，此外，若谓语动词后面的动作发生过了也用不定式，而-ing分词的基本含义一般则表示动作正在发生或进行。
