非谓语动词之“动词不定式”详解。
非谓语动词就是不充当谓语的动词，分两种。一是动词不定式。二是动词ing形式。
1） 作主语
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.+ 动词不定式。
如果要说明不定式表示的动作执行者，可以用for+sb.
it is + adj.+ for do sth.
2）作表语。
表语用来说明主语的身份、性质、品性、特征和状态的，表语常由名词、形容词、副词、介词短语、动词的-ing形式、不定式、从句来充当，它常位于系动词（be, become, appear, seem, look, sound, feel, get, smell等词）之后。）
my wish is to become a teacher.
3）作宾语或者宾语补足语。
most of us like to watch football matches.
he told me to be here on time.
4）作定语： i h**e nothing to say about that thing.
5）作状语： he stopped to h**e a look.
说明] 动词不定式的否定形式：not + to + 动词原形构成。
he asked me not to make such a mistake.
2、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。
(1) he doesn’t know how to use the machine.
2) how to use the machine is a question.
3) the question is when to go there.
3、省去了to 的动词不定式。
1）let, h**e, make+do
2）感官动词 see, watch, look at, notice, hear, listen to, smell, feel, find +to。
注意：在被动语态中则to 不能省掉。
i saw him dance. =he was seen to dance.
the boss made them work the whole night.=they were made to work the whole night.
3）would rather，had better + do
4、动词不定式的特殊句型：
1）too…to…+to do： he is too excited to speak.
2）enough to do： the child is old enough to go to school.
3）why not +do why not take a holiday?
4）so as (not) to do: 表示目的 go in quietly so as not to wake the baby.
5、不定式的难点：
1）用作介词的“to”：
比如说look forward to ; pay attention to; devote oneself tobe/get used to，后面都是+doing的！
2）it's for sb.和 it's of sb.的区别， ,动词ing形式分为两种，一是动名词，二是现在分词。
1．动词的-ing形式用作动名词：
动名词是动词的一种非谓语形式，由动词原形加-ing构成，它在句中起名词的作用，可以在句子中用作主语、表语、宾语、宾语补语、状语和定语。
1）动名词作主语： walking is good exercise. 走路是很好的运动。
2）动名词作表语 my f**orite sport is swimming. 我最喜欢的运动是游泳。
3）动名词作宾语： jim dislikes eating chocolate. 吉姆不喜欢吃巧克力。
she can’t help crying at a sad movie. 她看了忧伤的电影禁不住要哭。
说明] 有些动词和动词短语只能接动名词。
finish, forgive, give up, mind, practise, be good at, do well in, can't help, keep on, feel like, be used to, look forward to, prefer to,。
6）动名词作定语：动名词可以单独作定语，就像形容词一样。
a smiling face 笑脸 swimming pool 游泳池 dining-car 餐车。
2．动词的-ing形式用作现在分词：
ing分词通常用作宾语补足语，表示动作正在发生或者正在进行。这种用法通常用在下列动词中：see, hear, find, smell, watch, find, listen to, look at, notice, observe
we found him watching tv. 我们发现他在那儿看电视。
2）i heard someone knocking at the door. 我听见有人在敲门。
3．动词ing形式和动名词之间的比较：
下面这些动词，后面接不定式或动名词意思都是一样的：
