3、表语。e.g.Travelling abroad can be very exciting.观察 观察下列句子中动词-ing形式的用法，然后加以总结。1.Playing with fire is very dangerous.2.Seeing is believing.动词-ing形式作主语常用来表示经常性和习惯性的动作，通常放在_。句首3.It is very important rememberingothers names.4.It is no use crying over spilt milk.动词-ing形式作主语时，为了保持句子平衡，可以用it作形式主语，而动词-ing形式则放在

4、 _ 作真正的主语。如第3、4句。句中5.There is no good walking in the rain.在there is no结构中，通常用动词-ing形式作主语。观察 观察下列句子中动词-ing形式的用法，然后加以总结。1.They dont allow fishing in the lake.2.My mother advised asking a doctor to come and examine her eyes.有些动词后只能跟动词-ing形式作宾语，而不能跟动词不定式作宾语。如allow和advise。有此用法的动词还有：admit,appreciate,avoid

5、,bear,consider,delay,deny,enjoy,escape,finish,forbid,imagine,keep,mind,mention,permit,practice,quit,risk,suggest等。3.Lily remembered giving you the dictionary last afternoon.动名词有些动词后既可跟_，也可跟动词不定式作宾语，但用法和意义都有所不同。这些动词是：remember,forget,stop,regret,try,mean等。动词-ing形式用在动词need,want,require等后，用动词-ing形式的_形式或

6、者用不定式的被动式表示被动意义。如此句也可用The problem needs to be thought carefully 表示。4.The problem needs thinking carefully.主动5.I am proud of having won so many gold medals.6.She went away without saying goodbye.7.My father has been used to going to bed late and getting up very early.8.He has some difficulty in findi

7、ng her house.动词-ing形式作_宾语。动词要特别注意：be/get used to,look forward to,pay attention to,stick to,devote to等中的to都是介词而不是动词不定式符号。8.He has some difficulty in finding her house.9.He is busy preparing for a meeting this afternoon.be busy doing sth.,have trouble/difficulty(in)doing sth.,be worth doing sth.,spend

8、 some time/money(in)doing sth.,have a hard time(in)doing sth.都是惯用句型，其中的动词-ing形式不能换成不定式。10.Do you mind my/me/Sally/Sallys leaving now？如果要明确表示出动词-ing形式的逻辑主语，要在其前加上物主代词或名词所有格。注：动词-ing形式的否定式是在其前加not或never；完成式为“having+过去分词”；一般式的被动式为“being+过去分词”；完成式的被动式为“having been+过去分词”。用作表语，表示一般性、经常性的动作。如：The main thin

9、g is getting there in time.His main love is singing.动名词作表语时与进行时态中的现在分词形式相同，但其所属结构迥异，二者不可混淆。试比较：Her job was washing clothes.她的工作是洗衣服。（动名词作表语）She was washing clothes.她在洗衣服。（现在分词与was构成过去进行时，用作谓语。）用作定语。动名词作定语说明其所修饰名词的用途。而现在分词作定语，则表示其所修饰名词正在进行的动作。如：He may be in the reading room.Everybody was at his fight

10、ing post.There is a swimming pool at the back of the garden.(a swimming pool=a pool for swimming 动名词swimming作定语表示名词的用途)l like that dancing girl.(a dancing girl=a girl who is dancing 现在分词dancing作定语表示名词正在进行的动作)有一些复合动名词也可用作定语。如：peace-keeping troops维和部队练练1.Read each of the following sentences carefully
