不定式
一、形式功能 :
动词不定式:(to)+do,具有名词、形容词、副词的特征。
否定式:not + (to) do 以do为例,动词不定式的构成如下:
(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 nice to meet you. 很高兴见到你。
He seems to know a lot. 他看起来懂得很多。
We plan to pay a visit. 我们计划花钱去参观。
He wants to be an artist. 他想成为一个艺术家。
The patient asked to be operated on at once. 病人要求马上手术。
The teacher ordered the work to be done. 老师要求完成工作。
(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. 男孩假装工作得很努力。
He seems to be reading in his room. 看起来他正在他的房间里面读书。
(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 having told a lie. 我后悔我说谎了。
I happened to have seen the film. 我偶然看过这部电影。
He is pleased to have met his friend. 他很高兴能遇上他的朋友。
二、不定式的句法功能:
(1)作主语:
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 lose your heart means failure. 灰心意味着失败。
动词不定式短语作主语时,常用it作形式主语,真正的主语不定式置于句后,例如上面两句可用如下形式:
It is very hard to finish the work in ten minutes. 十分钟之内完成这项工作是很难的。
It means failure to lose your heart. 灰心意味着失败。
常用句式有:
(1)作主语:
1、It+be+名词+to do。
2、It takes sb.+some time+to do。
3、It+be+形容词+of sb +to do。
①与careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise,wrong , careful , polite , 等表示赞扬或批评的形容词连用,不定式前的sb.可作其逻辑主语。
②与for连用的通常是一些表示可能性、难易程度、必要性等含义的形容词: possible,impossible,easy,hard,difficult,necessary
It’s necessary for you to study hard .(necessary 修饰 to study hard,表示学习努力是有必要的)
It’s foolish of him to do it .(foolish 修饰逻辑主语him)
(2)作表语: 放be动词后,构成表语
Her job is to clean the hall. 她的工作是打扫大厅。
He appears to have caught a cold. 他似乎感冒了。
注意:
(3)作宾语:
①动词+不定式。如:

I find it hard to get along with him.(it 作形式宾语)
下列动词通常用不定式作宾语:want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, promise, prefer, like , begin , try , need , forget , agree , know , teach , help , arrange , dare , decide , determine , prepare , continue , ask , mean , choose , expect ,choose, get等
②动词+疑问词+to , “特殊疑问句+不定式”相当于名词,作宾语。如:
I don’t know what to do next/ how to do it next.
I can’t decide when to go there.
注意:不定式短语作宾语时,如果还带有宾语补足语,往往把不定式短语放在宾语补足语之后,用it 作形式宾语。如:

We think it important to obey the laws .
不定式动词可充当介词宾语,如:
I have no choice but to stay here. 我只能留在这里,别无选择。
He did nothing last Sunday but repair his bike. 他上周日除了修他的自行车什么也没干。
Marx found it important to study the situation in Russia. 马克思发现研究俄国的情况是很重要的。
(4)作宾语补足语:
①动词+宾语+不定式(to do )

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. 他有很多工作要做,所以没去电影院。
②表见解、看法的动词结构可为:动词+宾语+ to be 的不定式结构:

The book is believed to be useful.(被动语态)
③ There +不定式
We didn’t expect there to be so many people there.我们没料到会有那么多人在那里。
注意:(1)有些动词需用 as 短语作补语,像regard, think, believe, take, consider。如:

(2)在动词feel (一感),hear, listen to(二听),have, let, make(三让),notice, see, watch, observe, look at(五看)(即:吾看三室两厅一感觉)等后面的补足语中,不定式不带to,但变为被动语态后,必须带to。如:

(3)help后面作宾语补足语的不定式可以带to,也可以不带to.
I often help him (to)clean the room.
(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:

3)主谓关系:She is always the last ( person) to speak at the meeting . ----I’m going to the post office , for I have a letter to post .

4)动宾关系:

注意:如果作定语的不定式是一个短语,则要保留不定式短语中的副词或介词。如:

I have a little baby to look after .(I must look after the little baby ) (我有一个婴儿要照看)
He is looking for a room to live ? He is looking for a room to live in .
What did you open it with? 你用什么打开它?
如果不定式修饰time, place, way,可以省略介词:

He has no money and no place to live ( in ) .

(6)作状语:
①表目的:

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. 为了省钱,他使出了浑身解数。
wrong:To learn English well, a dictionary is needed. right:To learn English well, he needs a dictionary. 为了学好英语,他需要一本词典。
作目的状语:既可以放在句首,也可以放在句尾 To tell you the truth, I don't like the way he talked. 说实话,我不喜欢他讲话的方式。
②表结果(往往是与预期愿望相反的结果 意料之外): 常放在never only后

三、不定式的省略:

④由 and, or 和 than 连接的两个不定式,第二个 to 可以省去。如:He wants to move to France and marry the girl.
⑤help

⑨保留to省略do动词。 If you don't want to do it, you don't need to. 如果你不想做这件事,你就不必做。
⑩不定式的并列:第二个不定式可省略to。下列短语中,如果意义明确,常常省略到to:
want to , wish to ,hope to , like to , hate to , plan to , try to , love to , have to , ought to , need to , used to , be able to

动名词与现在分词作定语的区别:
(1)现在分词作定语表动作,它与所修饰的名词之间存在逻辑上的主谓关系,可改写成一个定语从句。
如果为单词,放在被修饰n之前,为短语,放在被修饰n之后。
如:a sleeping boy =a boy who is sleeping
a developing country =a country which is developing
(2)动名词作定语通常表示它所修饰的名词的用途或性质,可改写成一个for的短语,两者不存在逻辑上的主谓关系。
如:a washing machine = a mashine for washing
a swimming pool = a pool for swimming
He can't walk without a walking-stick. 他没有拐杖不能走路。
Is there a swimming pool in your school? 你们学校有游泳池吗?
(5)作同位语: The cave, his hiding-place is secret. 那个山洞,他藏身的地方很秘密。
His habit, listening to the news on the radio remains unchanged. 他收听收音机新闻节目的习惯仍未改变。
分词
一、现在分词和过去分词的区别:
1)在语态上,现在分词表示主动意义;过去分词表示被动意义,不及物动词的过去分词表示动作已经发生。
像:gone, fallen, retired, grown-up, escaped, faded, returned等词。如:a retired person 一个退休的人 a fallen ball 一个落下来的球
2)在时间上,现在分词表示的动作往往正在进行或者与谓语动词同时发生,过去分词表示的动作已经完成或没有一定的时间性。
如:falling leaves 正在下落的树叶 fallen leaves 已经落在地上的树叶
注意:分词作时间状语,如果先于主动词的动作,且强调先后,要用having done。如:
Having finished his homework, he went out for a walk.=After he had finished his homework, he went out for a walk.
二、注意:
1)分词作状语,其逻辑主语要与主句主语保持一致
2)分词前常有when / while / as / before/ after/ if / unless /even if 等引导词
3)如果过去分词的动作发生在主句谓语之前,用having been done Having been hurt in a traffic accident, I was given an operation.
4)分词做状语,主语之前不可有and /but / so / or/ so that 等连词(如有,则此句子为祈使句)
Working hard, you will succeed.
Working hard and you will succeed.
5)否定式,在分词之前+ not
6)固定搭配: be dressed in be lost in thoughts lost in thoughts, he knocked into me.
7)分词的逻辑主语与主句不同,分词要有自己的逻辑主语,称为“独立主语” The money used up, I had no food to eat
现在分词
二、定义: 既具有动词的一些特征,又具有形容词和副词的句法功能。
二、形式: 肯定式:V-ing; 否定式:not + 现在分词
(1)主动语态:现在分词主动语态的一般式表示与谓语动词所表示的动作同时发生,完成式表示的动作在谓语动词所表示的动作之前发生,常作状语。
例如:They went to the park, singing and talking. 他们边唱边说向公园走去。
Having done his homework, he played basket-ball. 做完作业,他开始打篮球。
(2)被动语态:一般式表示与谓语动词同时发生的被动的动作,完成式表示发生在谓语动词之前的被动的动作。
The problem being discussed is very important. 正在被讨论的问题很重要。
Having been told many times, the naughty boy made the same mistake. 被告诉了好几遍,这个淘气的孩子又犯了同一个错误。
三、现在分词的句法功能:
(1)作定语:现在分词作定语,当分词单独做定语时,放在所修饰的名词前;如果是分词短语做定语放在名词后。
In the following years he worked even harder. 在后来的几年中,他学习更努力了。
The man speaking to the teacher is our monitor's father. 正与老师谈话的那个人是我们班长的父亲。
现在分词作定语相当于一个定语从句的句法功能,如:in the following years也可用in the years that followed; the man speaking to the teacher可改为the man who is speaking to the teacher.
(2)现在分词作表语: The film being shown in the cinema is exciting. 正在这家上演的电影很棒。
The present situation is inspiring. 当前的形势鼓舞人心。
be + doing既可能表示现在进行时,也可能是现在分词做表语,它们的区别在于be + doing表示进行的 动作是进行时,而表示特征时是系动词be与现在分词构成系表结构。
(3)作宾语补足语:如下动词后可跟现在分词作宾语补足语:see, watch, hear, feel, find, get, keep, notice, observe, listen to, look at, leave, catch等。
例如:Can you hear her singing the song in the next room? 你能听见她在隔壁唱歌吗?
He kept the car waiting at the gate. 他让小汽车在门口等着。
(4)现在分词作状语:
①作时间状语: (While) Working in the factory, he was an advanced worker. 在工厂工作时,他是一名先进工人。
②作原因状语: Being a League member, he is always helping others. 由于是共青团员,他经常帮助他人。

⑤作结果状语: He dropped the glass, breaking it into pieces. 他把杯子掉了,结果摔得粉碎。
⑥作目的状语: He went swimming the other day. 几天前他去游泳了。
⑦作让步状语: Though raining heavily, it cleared up very soon. 虽然雨下得很大,但不久天就晴了。
⑧与逻辑主语构成独立主格:I waiting for the bus, a bird fell on my head.
All the tickets having been sold out, they went away disappointedly. 所有的票已经卖光了,他们失望地离开了。
Time permitting, we'll do another two exercises. 如果时间允许,我们将做另两个练习。
有时也可用with (without) +名词(代词宾格)+分词形式 With the lights burning, he fell asleep. 他点着灯睡着了。
⑨作独立成分: udging from(by) his appearance, he must be an actor. 从外表看,他一定是个演员。 Generally speaking, girls are more careful. 一般说来,女孩子更细心。
过去分词
一、形式:只有V-ed一种形式。(①规则,V-ed, ②不规则)
二、句法功能
1.过去分词作定语:
①单个过去分词做定语时用于被修饰的名词前,做前置定语 frozen food、polluted river、a terrified boy

③过去分词短语做定语时,用于被修饰的名词之后,相当于省略了which/who is/are:
A book written by luxun a student called Mary

The meeting held yesterday was important
The meeting to be held tomorrow is important.
2.过去分词作表语: The window is broken. 窗户破了。
They were frightened at the sad sight. 他们对眼前悲惨的景象感到很害怕。
注意:be + 过去分词,如果表示状态是系表结构,如果表示被动的动作是被动语态。
区别: The window is broken.(系表) The window was broken by the boy.(被动) 有些过去分词是不及物动词构成的,不表示被动,只表示完成。如: boiled water(开水) fallen leaves(落叶)
newly arrived goods(新到的货) the risen sun(升起的太阳) the changed world(变了的世界) 这类过去分词有:gone, come, fallen, risen, changed, arrived, returned, passed等。
