(1).在一般情况下，在动词原形后直接加词尾

–ing。

eg.

go – going; do – doing;

(2).在以不发音的e 结尾的动词后，去掉e，再加- ing。

eg.

come – coming

live – living

(3). 在闭音节的单音节动词后、以重读闭音节结尾的多音节动词，而末尾只有一个辅音字母时，将这个辅音字母双写（x除外），然后再加

–ing.

dig-digging （4）.在少数几个以

–ie 结尾的动词后：须将–ie 变作y，再加- ing。(这些动词词典一般均注明) eg. die – dying; tie – tying lie – lying

Step2.Presentation 1.动名词做主语

（1）Translate the following sentences:

阅读是一门艺术。Reading is an art.

爬山真是有趣。

Climbing mountains is really fun.

Tips: 直接位于句首做主语。

（2）Translate the following sentences: 和她争吵是没有用的。

It’s no use arguing with her. 吸烟是没有好处的，你最好放弃。

Tips :

使用形式主语it，而将动名词句尾。

动名词作主语的形式主语句型

1.It is no use /good doing….

2.It is not any use/good doing….

3.It is worthwhile doing….

4.It is hardly worth doing….

5.There is no doing….

6.It’s a waste of time doing….

2. 动名词做宾语

1）作动词的宾语

某些动词后出现非限定性动词时只能用动名词作宾语，不能用不定式。常见的此类动词有：advise, allow, permit, avoid, consider, enjoy, finish, give up, cannot help, imagine, include, keep, keep on, mind, miss, put off, delay, practise, resist, suggest, depend on, think about, set about, succeed in, worry about, burst out, insist on, can’t stand, be used to, get used to, devote…to…, look forward to, pay attention to, get down to等。如：

They went on walking and never stopped talking. 他们继续走，说个不停。

I found it pleasant walking along the seashore. 在海滩上走真是乐事。

为了便于记忆，特归纳如下：

后跟-ing的动词的顺口溜：

避免，错过，（少）延期avoid, miss, postpone/put off 建议，完成，（多）练习suggest, finish, practice 喜欢，想象，禁不住enjoy, imagine, can’t help

承认，否定，（又）妒忌admit, deny, envy 逃避，冒险，（多）原谅escape, risk, excuse 忍受，保持，（不）介意stand, keep, mind 2）作介词的宾语

He was late again because of getting up late. Lock the doors and windows before going out.

What/How about the two of us playing games？

注意：

to 在下列短语中是介词，常跟动名词作宾语。

be/get used to

look forward to get down to

pay attention to devote oneself to

lead to

contribute to

object to（反对）

eg: Let’s get down to preparing for the exam 3) 动名词用在下列词组后作宾语：give up, can’t help, feel like, be worth, be busy, set about, put off, think of，insist on等

eg: She can’t help crying at the sad sight.

4) 既可接动名词又可接不定式的常用动词有：remember, forget, regret, mean, try等，但表达的意义不同。

I remember seeing her at the hotel. 我记得在宾馆见过她。(动作发生了) I will remember to see her at the hotel. 我记着要去宾馆见她。(动作尚未发生) Step4 Homework 1. Prepare for the dictation 2
