功能

1. 不定式(infinitive)

1) 结构和用法:

动词不定式:(to)+do,在句中用作主语、表语、宾语、定语、状语、宾语补足语和主语补足语。

否定式:not + (to) do具体用法:

⑴动词不定式用作主语

不定式作主语时位于谓语动词之前,谓语用单数形式。

To finish the work in ten minutes is very hard.

十分钟之内完成这项工作是很难的。

To see is to believe.

眼见为实。

动词不定式短语作主语时,如果主语部分较长时,为保持句子平衡,常用it作形式主语,真正的主语不定式置于谓语之后。

It is very difficult to finish the work on time.

按时完成这项工作是非常困难的。

It’s a pleasure to help you.

帮助你我觉得很高兴。

It’s kind of you to help people who are in trouble.

你太善良了去帮助那些处于困难中的人。常用句式有:

① It+be+名词+to do。

② It takes sb.+sometime+to do。

③It+be+形容词+of sb+to do。

形容词careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise,等表示赞扬或批评的形容词,不定式前的sb.可作其逻辑主语。当表语是表示客观情况的形容词,其逻辑主语用for引出:当表语是不定式逻辑主语本身的特征和品质的形容词,其逻辑主语用of引出。

⑵不定式作表语:

不定式作表语位于系动词之后,解释主语的内容。

Her job is to clean the street.

她的工作是打扫大街。

He appears to have caught a cold.

不定式表语,通常表示将要作的具体动作

她的梦想是将来嫁一个富人。

⑶作宾语:不定式只做某些及物动词的宾语,常与不定式做宾语连接的有:want,hope,wish,offer,fail,plan,learn,pretend,refuse,manage,help,aim,promise,prefer等。

我想要辆小车。

He pretends to agree us.

他假装同意我们的想法。

Nancy managed to deal with the difficult situation.

南希设法处理这个困难的局势。

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:

Students nowadays find it important to learn English.

学生们如今发现学英语是很重要的。

动词不定式也可充当介词宾语,如:

我只能留在这里,别无选择。

动词know, give, tell, teach, explain, discuss, consider, discover, guess, understand等+不定式作宾语,动词不定式前有时可与疑问词when, whether, where, how,等连用,如:

他有很多工作要做,所以没去音乐会

有些感观动词如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:

看见他横过公路。

为了省钱,他使出了浑身解数。

wrong:To learn English well, a dictionary is needed.

不定式的并列:第二个不定式可省略to。

2)不定式的时态和语态

不定式属于非谓语动词,不能做谓语,但它具有动词的某些特征,动词不定式没有人称和数的变化,但具有时态和语态之分。以do为例。

例如:I like to study Chinese.

3)动词不定式动词表示的动作和谓语的关系。

⑴不定式一般式表示的动作可能与谓语动词的动作同时发生,也可能在其之后发生。

⑵不定式完成式表示不定式的动作在谓语动词之前发生。

⑶不定式进行式表示不定式的动作,与谓语动词同时发生。

例如:It’s a pleasure for me to be travelling with you at this time.

据说,这个新的博物馆去年已经建成了。

⑸在表示情绪的动词,如like, love, hate, prefer等后,用动名词作宾语表示一般倾向,用不定式表示特定某事。但在would/should like/love/prefer后要用不定式

例如:

I like swimming in summer.

我喜欢在夏天游泳。

Would you like to watch TV in the evening?

你喜欢每天晚上看电视吗?

⑹在动词need, want, require后用动名词表示被动含义,相当于动词不定式的被动式;而用动词不定式的主动式表示主动含义。

例如:

车需要修理了。

He needs to repair his the car.

他需要修理他的车了。

⑺在介词后一般用动名词作宾语,但在少数介词,如but, except后用动词不定式作宾语,但要注意“to”的省略,如but前有“do”则省去“to”。例如:

I have no choice but to accept it.

我没有选择只能接受。

2. 动名词(gerund)

概述:动词的-ing形式在起名词作用时,称为动名词,动名词在句中可以:主语、表语、宾语、定语。

2)动名词的时态和语态

因为动名词具有动词的特征,所以动名词本身具有时态和语态之分。动名词的时态分一般式和完成式两种,语态分主动形式和被动形式。

一般式的主动语态:doing

3.分词(participle)

分词的概述:英语中的分词分为现在分词和过去分词两种。二者在句中都可以做表语,定语,状语,宾语补足语,和主语补足语。

1)分词的用法

⑴分词做表语

现在分词做表语表示主语的特征,描述事物本身;过去分词做表语表示主语的状态或感受。例如:

The film is very interesting.

这部电影很有趣。

We are very interested in the film.

我们对这部电影很感兴趣。

⑵分词做定语

①现在分词做定语表示被修饰的名词主动发出,正在进行的动作;

过去分词做定语表示被修饰的名词被动接受,已经完成的动作。

例如:

The crying boy is very clever.

那个正在哭的男孩非常聪明。

The spoiled boy is very naughty.

那个被宠惯的男孩很调皮。

②分词做定语的位置

单个分词做定语放在被修饰名词的前面。

Her smiling face makes her look very beautiful.

她微笑的面孔使她看起来非常美丽。

分词短语作定语位于被修饰名词的后面。

The novels written by Qiong Yao are very moved.

琼瑶写的小说很感人。

⑶分词作状语

①分词作状语时,通常放在句首,并且用逗号与主句隔开。同时,分词作状语时其逻辑主语与主句主语应保持一致,也就是说在确定选择现在分词还是过去分词时,要判断主句主语与分词中心词的关系。如果句子的主语是动词-ing形式所表示的动作的发出者(即表主动或正在进行),分词形式选用现在分词;如果句子的主语是动词-ed形式所表示的动作的承受者时(即表被动或完成),分词形式选用过去分词。例如:

Seeing the book falling from the desk, I picked it up immediately.

我看见书从桌子上掉下来,立即捡起来。

Seen from the hill, the park looks very beautiful.

从山上看这个公园是非常的美丽。

②分词作状语时其逻辑主语与主句主语应保持一致,但当分词逻辑主语与主语不一致时,分词要有自己独立的逻辑主语,也叫分词的独立主格结构。此时分词形式的选择取决于名词/代词与v-ing/v-ed形式所表示动作的逻辑关系,如果它们之间表示主动或分词动作正在进行,选择现在分词,如果它们之间表示被动或完成,选择过去分词。

名词/代词+动词-ing例:

Autumn coming on, the trees turned yellow..

秋天来了,树叶变黄了。

名词/代词+动词-ed

例:The work done, they felt released.他们完成了工作,都松了一口气。

with/without+名词/代词+动词-ing/-ed

例:

My hometown looks beautiful with the flowers coming out.

当花儿开放的时候,我的家乡看起来很漂亮。The battle was over without a shot being fired.

战争结束了,没有费一枪一炮。

③分词做状语,表示时间、原因、结果、方式。

现在分词做状语,表示句子主语主动发出,正在进行的动作。

过去分词做状语,表示句中主语被动接受,已经完成的动作。

A.表时间

尽管受到了父母的鼓励, 他仍然没有信心克服困难。

⑷作宾语补足语

分词作宾语补足语补充说明宾语发生的动作和存在和状态。

现在分词作语补足语,表示句子主语主动发出,正在进行的动作。

过去分词作语补足语,表示句中主语被动接受,已经完成的动作。

①感官动词see, watch, notice, find, observe, catch, hear, feel等后面作宾补。如:

He saw a thief stealing a wallet from a lady’s handbag.

她看见一个小偷正在偷一位女士的钱包。

He saw the wounded man carried into the hospital.

她看到那个受伤的男人被抬进了医院。

注:非谓语动词用在感官动词后作宾补的区别:不定式(不带to)常表示动作已结束,强调动作的全过程;现在分词表示正在进行的动作,强调当时的情景,为部分过程;过去分词与宾语之间为被动关系或表示动作已完成。

②用在使役动词have, make, get, keep, leave等后面作宾补。如:

I keep working in order to finish ahead of time.

我不停地工作目的是提前完成。

He managed to get the task finished on time.

他设法按时完成了任务。

注:

在“have+宾语+宾补”结构中,充当宾补的有do,doing和 done。do表示主动,动作可能发生;doing表示主动,动作在持续;have sth. done请别人来做某事或遭遇到某情况。

在“make+宾语+宾补”结构中用do或done而不用doing作宾补。

“keep/leave+宾语+宾补”,宾补由过去分词、现在分词等充当。

作主语补足语

分词作主语补足语补充说明主语发生的动作和存在和状态。

现在分词作主语补足语,表示主语主动发出,正在进行的动作。

过去分词作主语补足语,表示主语被动接受,已经完成的动作。

例如:

A drunken person was seen singing madly in the street.

一个喝醉的人被发现在街上发疯似的唱歌。

A stolen bike was found hidden in the old warehouse.

一辆被偷的自行车被发现藏在旧仓库里

2)分词的时态和语态

因为分词具有动词的特征,所以分词本身也有时态和语态之分。分词的时态分为现在时和完成时。

⑴分词的现在时表示分词的动作和谓语动词同时。

分词的现在时:主动语态 doing; 被动语态 done

Cleaning my bedroom, I find my lost pen.

在打扫卧室的时候,我发现了我丢失的笔。

Hearing the news, he jumped with joy.

听到这一消息,他高兴得手舞足蹈。

⑵分词的完成时表示分词的动作在谓语动词之前。

完成时的:主动语态having done; 被动语态 having been done

Having finished my job, I went to home.

完成工作之后,我就回家了。

Having been burned at night, the building can’t permit people to enter.

这个建筑物在夜里着火之后,就不允许人进入了。

4.非谓语动词用法辨析

2)非谓语动词在同一成分中用法的辨析

①目的状语:通常有不定式表示,由于不定式的客观性和将来性特征。不定式前还可加上in order,so as来加强说话的口气。但so as to通常不用于句首。

②时间状语:分词作时间状语相当于时间状语从句。现在分词作时间状语一般位于句首,表示的动作和谓语动词的动作同时发生,有时现在分词前可以加上时间连词。如果分词动作发生在谓语动词之前,用现在分词的完成体形式。过去分词作时间状语与谓语动词构成同时性和被动意义。分词前有时加上时间连词。

⑤结果状语从句:不定式作结果状语通常用于so+形容词或副词+as to,such+名词+as to,too…to,enough to和only to等结构。
