Remember to review the knowledge! See you next time!

Useful structure

The –ing form as the Subject &Object
1.作主语 动名词作主语时,句子有两种形式: ①动名词直接置于句首主语的位置上。 1) 捉弄别人是我们万万不能干的. Playing tricks on others is something we should never do. 2)学习新单词对我来说非常重要。 Learning new words is very important for me. 3)说比做容易。 Talking is easier than doing.

②用形式主语it,把真正的主语——动名词结构 移置句尾。但这种句子形式有一定的限制,作表 语的只能是某些形容词或少数名词,如useful, useless,good,fun;no use,worth等。如: 和夏洛克争辩是没有什么用的。 It is useless trying to argue with Shylock. 这事值得去做。 It’s worth making the effort. 想再解释一次有好处吗? Is it any good trying to explain? 跟你在一起工作是令人愉快的。 It is pleasant working with you.

③在there be结构中作主语,这种结构的意思相 当于“It is impossible to do… ”。例如: 若要人不知,除非己莫为。 There is no hiding of evil but not to do it. 这种事开不得玩笑。 Here is no joking about such matter. 无法知道他什么时候离开 There was no knowing when he would leave.

动名词与不定式做主语时的比较: 动名词表示的动作通常是一个泛指的动作,不定 式则通常表示具体的动作。如: 还是个孩子的时侯,她就觉得探视病人是一种责 任,也是一种愉悦。 As a child,she felt that visiting sick people was a duty and a pleasure. 到美国人家里做客对我来说将是一个极好的经历。 Being a guest in an American home will be a good experience for me.

一直不做就是作恶。 Doing nothing is doing ill. 他说:“继续这样下去是无用的。” He said,“To go on like this is no use.” 我很荣幸被邀请参加这个晚会。 It’s an honor for me to be invited to the party.

归纳:常用-ing形式作主语的句型有: It +be +a waste of time doing 做、、、是浪费时间的 It is/was no good/use doing 做、、、是没用处的 It is/was hardly/scarcely worth doing 做、、、不值得 It is/was worth/worthwhile doing 做、、、是值得的 There is no doing 无法、、、, 不允许、、、

There is no sense in doing 做、、、没有道理 There is/was no use doing 干、、、无意义 There is/was nothing worse than doing 没有比、、、更糟的 There is/was no point doing 干、、、无意义 我们不知道要去哪儿。 There was no knowing where we would go. 做这件傻事毫无意义。 There is no point doing such a silly thing.

注意:There is no need to do sth 干、、、没 必要,在此句式中to do 不可换为doing.. 没有必要告诉她。 There is no need to tell her. 提示:当动名词用作主语时,其逻辑主语由 形容词性物主代词和名词所有格构成。 我姐姐病了,使我很担心。 My sister's being ill made we worried. 你正确未必就意味着我错了。 Your being right doesn't necessarily mean my being wrong.

2、用作宾语 动名词作宾语有两种情况。一是有些动词只能后接动名词作宾语; 二是有些动词既可后接动名词也可后接不定式作宾语。 ①只能后接动名词作宾语的动词,常见的有avoid,consider, enjoy,keep,finish,suggest,dislike,delay,escape,cannot help,imagine,mind,miss,practise,cannot stand等。如: 我不能不去。 I can’t avoid going. 你是否考虑过找一位挚友? Have you considered looking for one special friend?

我们必须设法避免犯同样的错误。 We must try to avoid repeating the same mistake. 晚饭后你想和我一起散步吗? Do you feel like having a walk with me after supper? 人们忍不住嘲笑那个愚蠢的人。 People couldn’t help laughing foolish man. 这类动词还有:excuse,fancy,give up,

②既可接动名词又可接不定式作宾语的动词, 常见的有:begin,start,continue,like, love,prefer,by,mean,forget,remember, hate等。 · A.在like,love,hate,prefer等动词之后, 用-ing或不定式意义上没有什么不同,只是侧 重点有些不同,动名词表示泛指的动作,不 定式表示具体的一次性动作。 B.在begin/start,continue之后,用动名词 和不定式,意义无甚区别,尤其是当主语是

C.在动词forget,remember,regret之后,用动名词与不定式意义不同。 动名词表示动作先于谓语发生,不定式表示后于谓语动作,如: 我记得我已把信寄了。 I remember posting the letter. 我会记着去寄信的。 I’ll remember to post the letter. 我永远不会忘记见到过那位著名作家。 I shall never forget seeing the famous writer. 不要忘了给你母亲写信。 Don’t forget to write to your mother. 我真后悔没赶上那次报告会。 I regret missing the report. 我遗憾地告诉你我不能接受你的建议。 I regret to say I can’t take your advice.

D.在try,mean之后,意义各不相同,如try to do (设法),try doing (试试),mean to do (打算,有意要做),mean doing (意思是, 意味着)。如: 我们必须设法及时把一切搞好。 We must try to get everything done in time. 我们用别的方法做这工作试试。 Let’s try doing the working in some other way. 我并不想叫你生气。 I didn’t mean to make you angry. 你的计划意味着要花费几个小时。 Your plan would mean spending hours.

E· on doing 和go on to do go Go on doing继续做一直在做的事;go on to do接着 做另一件事。如: 请接着做这同一个练习。 Please go on doing the same exercise. 请做另外一个练习。 Please go on to do the other exercise. F.stop doing与stop to do: Stop doing停止做, stop to do停下正在干的事去干另一件事。如: 我们停止了交谈。 We stopped talking. 我们停了下来去谈话。 We stopped to talk.

3.作介词宾语 动名词可与介词一起构成介词短语。 A.介词+动名词,如: 我们得想些法子改变人们的习惯。 We’ve got to think of ways of changing people’s habits. 我向你道歉,刚才对你那样生气。 I apologize for being so angry with you. 离开几年之后再回到你生长的地方,感觉有点怪。 After being away for several years,it is a strange experience to return to the place you were born and brought up.

B.动词+介词+动名词,如: 我坚持为这次出行带足需要的食物。 I insist on taking proper food fort his expedition. 同学们脸上没有笑容,相反都做了怪脸。 Instead of smiling,each of them made a face. 她对为我们公司工作很感兴趣。 She was very interested in working for our company. 下列短语中的to都是介词,所以后面跟名词 或-ing形式:devote to,object to,pay attention to,get down to,lead to, look

1. ____ such heavy pollution already, it may now be too late to clean up the river.( 2004全国 ) A. Having suffered B.Suffering C. That D. Suffered
精析:根据句意“it may now be too late to …” 和 “already”可知“河流已经被严重 污染”,应用完成时。答案A。

2. ____ the general state of his health, it may take him a while to recover from the operation. ( 全国2002) A. Given B. To give C. Giving D. Having given
解析:本题考查过去分词作状语的用法。分 析题干,前一部分相当于一个条件状语从句, 即If he is given …,因为主句是 it,从句应 含被动意义,这恰是过去分词作状语的基本 含义即含被动意义。答案 A。

3. ---- The picture ____ on the wall is painted by my niece.( 2001上海) A. having hung B. hanging C. hangs D. being hung 解析:本题考查过去分词作定语的用法。分析题 目可知,谓语是is painted,那么选项部分应是 充当定语的。A项是现在分词的完成式,其一般 不作定语,只作时间或原因状语;C项动词“第 三人称单数”显然也不能作定语,只作谓语;分 析 the picture与动作 hang之间的关系,其不含 被动意义,D项排除; B项是现在分词的一般式, 相当于定语从句which is hanging。答案B。
