1. 什么是非谓语
在英语中,不作句子谓语,而具有除谓语外其他语法功能的动词,叫做非谓语动词。
非谓语动词有动词不定式(the Infinitive);动名词(the Gerund);现在分词(the Present Participle);过去分词(the Past Participle)。 1.非谓语动词与谓语动词的相同点有: (1)如果是及物动词都可与宾语连用,例如: They built a garden. They suggested building a garden. (2)都可以被状语修饰: The suit fits him very well. The suit used to fit him very well. (3)都有主动与被动, “体”式(一般式;进行式;完成式)的变化。
例如: He was punished by his parents.(谓语动词被动语态) He avoided being punished by his parents.(动名词的被动式) We have written the composition.(谓语动词的完成时) Having written the composition, we handed it in.(现在分词的完成式) (4)都可以有逻辑主语 They started the work at once.(谓语动词的逻辑主语) The boss ordered them to start the work.(动词不定式的逻辑主语) We are League members.(谓语动词的主语) We being League member, the work was well done. (现在分词的逻辑主语) 2、非谓语动词与谓语动词的不同点有: (1)非谓语动词可以有名词作用(如动词不定式和动名词),在句中做主语、宾语、表语。 (2)非谓语动词可以有形容词作用(如动词不定式和分词),在句中做定语、表语或宾语补足语。
(3)非谓语动词可以有副词作用(如动词不定式和分词),在句中作状语。 (二)非谓语动词的句法功能: 二、非谓语动词用法: (一)动词不定式:(to)+do,具有名词、形容词、副词的特征。
1.不定式的形式:(以动词write为例) 否定式:not + (to) do (1)一般式:不定式的一般式所表示的动作与谓语动词动作同时发生或发生在谓语动词动作之后, 例如: I'm glad to meet you. He seems to know a lot. We plan to pay a visit. He wants to be an artist. The patient asked to be operated on at once. The teacher ordered the work to be done. (2)进行式:不定式的进行式所表示的动作与谓语动词动作同时发生,例如: The boy pretended to be working hard. He seems to be reading in his room. (3)完成式:不定式的完成式表示的动作发生在谓语动词动作之前,例如: I regretted to have told a lie. I happened to have seen the film. He is pleased to have met his friend. 2.不定式的句法功能: (1)作主语: To finish the work in ten minutes is very hard. To lose your heart means failure. 动词不定式短语作主语时,常用it作形式主语,例如上面两句可用如下形式: It is very hard to finish the work in ten minutes. It means failure to lose your heart. (2)作表语: Her job is to clean the hall. He appears to have caught a cold. (3)作宾语: 常与不定式做宾语连用的动词有:want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer, 如果不定式(宾语)后面有宾语补足语,则用it作形式宾语,真正的宾语(不定式)后置,放在宾语补足语后面,例如: Marx found it important to study the situation in Russia. 动词不定式也可充当介词宾语,如: I have no choice but to stay here. He did nothing last Sunday but repair his bike. 动词不定式前有时可与疑问词连用,如: He gave us some advice on how to learn English. (4)作宾语补足语: 在复合宾语中,动词不定式可充当宾语补足语,如下动词常跟这种复合宾语:want, wish, ask, tell, order, beg, permit, help, advise, persuade, allow, prepare, cause, force, call on, wait for, invite. 此外,介词有时也与这种复合宾语连用,如: With a lot of work to do, he didn't go to the cinema. 有些动词如make, let, see, watch, hear, feel, have等与不带有to的不定式连用,但改为被动语态时,不定式要加to, 如: I saw him cross the road. He was seen to cross the road. (5)作定语: 动词不定式作定语,放在所修饰的名词或代词后。与所修饰名词有如下关系: ①动宾关系: I have a meeting to attend. 注意:不定式为不及物动词时,所修饰的名词如果是地点、工具等,应有必要的介词,如: He found a good house to live in. The child has nothing to worry about. What did you open it with? 如果不定式修饰time, place, way,可以省略介词: He has no place to live. This is the best way to work out this problem. 如果不定式所修饰名词是不定式动作承受者,不定式可用主动式也可用被动式: Have you got anything to send? Have you got anything to be sent? ②说明所修饰名词的内容: We have made a plan to finish the work. ③被修饰名词是不定式逻辑主语: He is the first to get here. (6)作状语: ①表目的: He worked day and night to get the money. She sold her hair to buy the watch chain. 注意不定式放句首时,逻辑主语与句子主语要一致: wrong:To save money, every means has been tried. right:To save money, he has tried every means. wrong:To learn English well, a dictionary is needed. right:To learn English well, he needs a dictionary. ②表结果。
2. 非谓语是什么 举些例子
非谓语动词主要包括不定式、动名词和现在分词。
为了区分这三种不同的非谓语动词的用法和含义,我们将分别从三种非谓语动词在句子中做主语、宾语、宾语补足语、定语、状语、表语以及一些特殊结构句型等角度来区分其用法和细微含义。1.不定式和动名词作主语的区别(1)动名词作主语通常表示抽象动作;而不定式作主语表示具体动作。
Smoking is prohibited(禁止)here.这里禁止抽烟。(抽象)It is not very good for you to smoke so much.你抽这么多烟对你身体很不好。
(具体)(2)动名词作主语时,通常用以表示一件已知的事或经验。不定式短语通常用来表示一件未完成的事或目的。
Climbing mountains is interesting.爬山很有趣。(经验)Driving a car during the rush hour is tiring.在高峰时刻开车令人厌烦。
(经验)(3)不定式做主语,一般用it当形式主语,把作主语的不定式短语后置。It took me only five minutes to finish the job.2.不定式、动名词和分词作表语的区别(1)不定式作表语1)不定式作表语一般表示具体动作,特别是表示将来的动作。
To do two things at a time is to do neither.--次做两件事等于未做。What I would suggest is to start work at once.我的建议是立刻开始干。
2)如果主语是不定式(表示条件),表语也是不定式(表示结果)。To see is to believe.百闻不如一见To work means to earn a living.工作就是为了生活。
3)如果主语是以aim,duty,hope,idea,happiness,job,plan,problem,purpose,thing,wish等为中心的名词,或以what引导的名词性从句,不定式作表语是对主语起补充说明作用。His wish is to buy a luxurious car in the near future.他的希望是在不远的将来买一辆豪华轿车。
The function of Louis Sullivan's architecture was to provide large uninterrupted floor areas and to allow ample light into the interior. The most important thing is to negotiate with them about the future of the plant.(2)动名词作表语:动名词作表语,表示抽象的一般性的行为。 Our work is serving the people.我们的工作是为人民服务。
His hobby is collecting stamps.他的爱好是集邮。(注)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,进行时态说明动作是由主语完成的。
动名词做表语,说明主语的性质或情况。 People cannot but feel puzzled,for they simply cannot understand how he could have made such a stupid mistake.His victory in the final was no more convincing than I had expected.(3)分词作表语分词做表语有两种情况,一种是现在分词做表语,一种是过去分词做表语,这两者区别是考试中经常考到的地方。
一般来说,表示心理状态的动词如excite,interest等都是及物动词,汉语意思不是“激动”,“高兴”,而是“使激动”、“使高兴”,因而现在分词应该是“令人激动的”、“令人高兴的”,过去分词则是“感到激动的”和“感到高兴的”。所以,凡表示“令人……的”都是-ing形式,凡是表示“感到……”都用-ed形式。
换句话说,若人对……感兴趣,就是somebody is interested in。,若人/物本身有兴趣时,就是说sb./sth. is interesting.这类词常见的有:interesting使人感到高兴--interested感到高兴的exciting令人激动的--excited感到激动的delighting令人高兴的--delighted感到高兴的disappointing令人失望的--disappointed感到失望的encouraging令人鼓舞的--encouraged感到鼓舞的pleasing令人愉快的--pleased感到愉快的puzzling令人费解的--puzzled感到费解的satisfying令人满意的---satisfied感到满意的surprising令人惊异的--surprised感到惊异的worrying令人担心的--worried感到担心的Travelling is interesting but tiring.旅行是有趣的,但是使人疲劳。
The pupils will get confused if they are made to learn too much.如果要学生学得太多,他们会感到糊涂的。The argument is very convincing.他的论点很令人信服。
They were very excited at the news.听到这个消息,他们非常激动。3.不定式和动名词作宾语的区别 英语中大多数动词既可跟不定式,也可跟动名词作直接宾语,但有些动词要求: (1)不定式做宾语和宾语补足语1)下面的动词要求不定式做宾语attempt企图 enable能够 neglect忽视afford负担得起 demand要求 long渴望arrange安排 destine注定 mean意欲,打算begin开始 expect期望 omit忽略,漏appear似乎,显得 determine决定 manage设法cease停止 hate憎恨,厌恶 pretend假装ask问 dread害怕 need需要agree同意。
