昨天我见他正在花园里干活。（强调"我见他正干活"这个动作）

感官动词后面接形容词而不是副词：The cake tastes good;It feels comfortable.

2)使役动词have bid make let等词后不定式要省略但同1)一样被动以后要还原to

I‘d like to have John do it.

I have my package weighed.

Paul doesn’t have to be made to learn.

3)help help sb do help sb to do help do help to do

四)有些动词后只跟不定式如：

want，wish，hope，manage，promise，refuse，pretend，plan，offer，decide，agree，expect allow sb to do,cause sb to do,permit sb to do,enable sb to do

force sb to do.be more likely to do love to do warn sb to do be able to do

be ambitious to do.begin to do.start to do

五)有的时候to后面要接-ing形式

accustom(oneself)to;be accustomed to;face up to;in addition to;look forward to;object to;be reduced to;resign oneself to;be resigned to;resort to;sink to;be used to;be alternative to;be close/closeness to;be dedication/dedicated to;be opposition/opposed to;be similarity/similar to.

三、need/want后的-ing形式具有被动的意思。其中，want不太常用。

He needs(a lot of)encouraging.

二.动名词：具有动作性特征的名词

1)是名词seeing is believing

2)具有动词性特征可以带宾语starving troops is necessary.

一)动名词的形式:

一般形式：I don't like you smoking.

完成形式：I regret not having taken your advice.

被动形式：This question is far from being settled.

二)动名词常考的点

1)动名词做主语谓语动词为单数

2)在动名词和不定式中,做为介词的宾语是动名词

3)动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语.

I would appreciate back this afternoon．

A．you to call B．you call C．you calling D．you're calling（Key：C your calling也对）

I regret not having taken your advice.

4)有些词后只能接动名词

admit;appreciate;avoid;celebrate;consider;contemplate;defer;delay;deny;detest;discontinue;dislike;dispute;enjoy;it entails;escape;excuse;explain;fancy;feel like;finish;forgive;can't help;hinder;imagine;it involves;keep;it means;mention;mind;miss;it necessitates;pardon;postpone;practice;prevent;recall;report;resent;resist;risk;suggest;understand...

另外还有一些接-ing形式的常用说法：

it's no good;it's no/little/hardly any/use;it's not/hardly/scarcely use;it's worthwhile;spend money/time;there's no;there's no point in;there's nothing worse than;what's the use/point...

5有些词后加不定式和动名词均可

remember,forget,try,stop,go on,cease,mean后面用不定式和-ing形式，意义截然不容。

I remembered to post the letters.(指未来/过去未来的动作)

I remembered posting/having posting the letters(我记得这个动作)

forgot与remember的用法类似。

I regret to inform you that…我很遗憾地通知你…

I regretted having left the firm after twenty years.为了"二十年前的离开"而遗憾。
