it,.,2,）动名词的名词性质表现在：在句中可用作主语、宾语、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

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,_,作真正的主语。如第,3,、,4,句。,总结,句中,5.There is no good,walking,in the rain.,总结,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.,二、动词-ing形式作宾语,总结,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,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.,总结,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.,总结,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,finding,her house.,总结,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.,总结,be busy doing,sth,.,have trouble/difficulty(in)doing,sth,.,be worth doing,sth,.,spend 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,？,总结,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 thing 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：,三、动词-ing形式作表语,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,fighting,post.,四、动词-ing形式作定语,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 and decide whether there is a mistake or not.If yes,mark and
