B、动名词
动名词可以起名词的作用,在句子中作主语,宾语,表语,定语。动名词仍保留动词的一般特征,可以有自己的宾语和状语,构成动名词短语。 动名词的否定形式是在前面加上not, never等否定词。
(一)做主语和表语。动名词短语用and连起来做主语时,谓语用复数形式。例如:
Fishing in this lake is forbidden. 这个湖里禁止钓鱼
Going abroad for a visit and settling down abroad are two different things. 出国访问和在国外定居是两件不同的事情。
It seems that reading English is easier than speaking it.似乎读英语比说英语容易。
My favorite hobby is fishing/collecting stamps . 我最喜欢的爱好是钓鱼/集邮。
在It’s no use; It’s (no) good; It’s useless ; It’s (not) wise; It’s (not) worthwhile; It’s ofgreat (no, little) importance 等习惯表达中,It为形式主语,而将做主语的动名词短语放在后面。例如:
It’s no use /good ringing her up now. 现在给她打电话没用了。
Is it worthwhile bargaining two hours for two cents? 为两分钱讲价两小时值得吗?
It’s wise trying again. 再试一次是明智的。
It is of great importance fighting against pollution. 制止污染有重要意义。
It is no use operating on the sick man. He should have been sent here early. 给这个病人做手术已经没用了。本应该早些把他送来。
It is no good smoking; you’d better give it up. 吸烟没好处,你最好戒掉。
(二)动名词短语作宾语。
常用的能接动名词的动词有:admit承认,appreciate 感激,avoid 避免,advise 建议,can’t help 不禁,celebrate 庆祝,consider 考虑,complete 完成, contemplate沉思、打算,defer推迟,delay 延期,deny 否认,detest 痛恨,discontinue 停止, dislike不喜欢,dispute不同意,endure 忍耐,enjoy 喜欢, escape逃脱,excuse 原谅, fancy想象,feel like 想要, finish结束, 严禁,forgive 原谅,hinder 阻碍,imagine想象,keep 保持,mention 提到,mind 在意,miss 错过,pardon 饶恕、原谅,permit允许,postpone 推迟,practise 实践、练习,prevent 阻止, recall 回忆, report报告,resent 怨恨, resist抵制、阻止,risk冒险,stop 停止,suggest 建议,understand 明白、理解,等等。例如:
He avoided giving me a definite answer. 他避免给我一个正确答案。
David suggested selling your dog and car to pay the debt. 戴维建议卖掉你的狗和车抵债。
(我们把这句话改为虚拟语气:David suggested that you (should) sell your dog and car to pay the debt. )
I couldn’t risk missing that train. 我可不敢冒误了那趟火车的险。
下列动词既可用动词不定式又可用动名词做宾语:
abhor憎恶,attempt 试图,begin 开始,cannot bear 无法忍受,cannot stand无法忍受,cease停止,continue,继续,,decline 拒绝,deserve值得,disdain蔑视,dread害怕,endure忍耐,forget忘记,hate 痛恨,intend打算,learn学,like 喜欢,loathe厌恶,love喜欢,mean意思是、意味着,need需要,neglect疏忽,omit省略,忽略,plan计划,prefer更喜欢,propose建议,regret后悔,remember记得,require需要,scorn蔑视、瞧不起,start开始,try尝试,努力,entail必须,involve涉及,necessitate使成为必要,等。以上多数动词用不定式或用动名词作宾语意思一样,个别不同。
(三)动名词短语作介词宾语的时候最多。
尤其是在短语动词后面。如:
The children are fond of listening to pop music. 孩子们喜欢流行音乐。
Are you interested in going to the show? 你有兴趣去看演出吗?
Thomas insisted on doing it in his own way. 托马斯坚持按他自己的方法做这件事。
我们把这句话改为虚拟语气:Thomas insisted that he (should) do it in his own way.
Excuse me for interrupting you. 请原谅我打扰你,
Since returning from Xi’an, he has been busy. 从西安回来后,他一直很忙。
He warned me againstmming in this lake. 他警告我不要在这个湖里游泳。
改为不定式短语:He warned me not tom in this lake.
We came out without being seen. 我们出来没被人看见。
Before finishing your homework, you’d better not go out. 做完作业之前,你最好别出去。
改为用before 作连词:Before you finish your homework, you’d better not go out.
(四)动名词也可以有自己的逻辑主语,就是在动名词短语前面加上物主代词或名词的所有格。
带逻辑主语的动名词短语可做主语,宾语,表语等。在非正式文体当中,经常把物主代词简化为宾格人称代词,把名词
所有格简化为名词。例如:
I insisted on his (him) going to the cinema with me. 我坚持要他和我一起去看电影。
I can hardly imagine Peter(Peter’s) sailing across the Atlantic Ocean in five days. 我简直不能想象彼得会在五天内横渡大西洋。
Linda’s coming will do you good.(主语) 林达的到来对你有好处。
What made him angry was their (them) laughing.(表语)使他生气的是他们笑。
(五)动名词的完成式和被动语态:
(1)完成式表示动名词的动作发生在谓语动作之前。例如:
I apologize for having broken my promise. 我没有遵守诺言,我道歉。
I don’t remember having talked with him before. 我不记得以前曾和他谈过话。
I regret not having met you before my marriage/before I got married. 恨不相逢未嫁时。
(2)当动名词的逻辑主语是动名词动作的对象或承受者时,动名词要用被动语态。例如:
I could no longer stand being treated like that. 我再也不能忍受被那样对待。
She was proud of having been trained in the U.K. 在英国受过训,她感到自豪。
他不喜欢嘲笑别人。 →He doesn’t like laughing at others.
他不喜欢被人嘲笑。→He doesn’t like being laughed at.
(六)某些动词可接不定式也可接动名词做宾语,但意义有差别。
(1)like, love, hate, prefer等表示喜爱,厌恶的动词后面,可用动名词也可用不定式作宾语,意义差别不大。但当这些词前面有should或would时,一定要用动词不定式作宾语。表示想要,愿意,打算。例如:

(2) forget to do sth.忘记去做某事(未做) forget doing sth.忘记做过某事(已做) 例如:

C、分词
分词有现在分词和过去分词两种。
作为谓语,现在分词和be 一起构成进行时;过去分词和be一起构成被动语态,和have一起构成完成时。例如:
I am reading a novel by Maupassant. 我正在看一本莫泊桑写的小说。(现在分词和be 一起表示主语正在进行的动作。)
Mr. Robinson has drunk five glasses of wine already. 鲁宾逊先生已经喝了五杯酒了。(过去分词和have 一起表示主语已经完成的动作。)
The gold fish bowl was broken by Xiao Tao just now. 金鱼缸刚才被小陶打破了。(过去分词和be 一起表示主语是动作的承受者。)
作为非谓语形式,分词可用作形容词和副词,在句子中充当定语、表语、补语和状语。但它仍保持动词的一般特征,可以有自己的宾语和状语。分词和自己的宾语、状语构成分词短语。
现在分词有一般式和完成式。它的一般式表示和谓语动词所表示的动作同时发生的行为或存在的状态;它的完成式(having + 过去分词)表示在谓语动词所表示的动作之前发生的动作或存在的状态。
现在分词有主动语态和被动语态(being + 过去分词)。
过去分词只有一般式,表示在谓语动词所表示的动作之前发生的动作。过去分词(及物动词)本身可以表示被动的含义,因而没有别的被动形式。例如:
Having failed three times, he didn’t want to try again. (=As he had failed three times, he didn’t want to try again.) 他失败了三次,不想再干了。(having failed 表示发生在前的动作)
Walking along the sands, Crusoe saw in the sand the mark of a man’s foot. (=While he was walking along the sands, Crusoe…) 克鲁索沿着沙滩走的时候,看见沙上有人的脚印。(walking 表示同时发生的动作)
The question being discussed seems important. (=The question is being discussed. It seems important.) 正在讨论的问题似乎很重要。
The old days are gone. 旧时代一去不复返了。(gone 表示完成的状态)
I had my hair cut yesterday. 我昨天理发了。(cut 是及物动词的过去分词,表示“被人理发”。)
分词的否定形式是在分词短语前面加上not, never等否定词构成。例如:
Not fearing the fire, the child touched and got a finger burnt. 小孩儿不知道怕火,用手去摸,把手指烫了。
Not knowing how to find the subway, I asked a policeman for help. 我不知道怎样找到地铁,就去找警察帮忙。
