新人教版高二英语必修三知识点范文经典 1

一、不定式做主语：

1、不定式做主语一般表示具体的某次动作。===动名词doing 表示习惯的，经常的动作。

e.g: To finish the building in a month is difficult.

To do such things is foolish.

To see is to believe. (对等)

注: 1). 不定式作主语时,谓语用单数

2). 当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。

it做形式主语，不定式放在谓语动词之后常用于下列结构中：

(1)It is/was +adj.+of sb. to do…

(2) It is +adj.+for sb.+to do…

It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary

(3) it is +a +名词+ to do...

It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do

It takes (sb.) some time / courage / patience …to do…

It requires courage / patience / hard work… to do…

_注意: probable 和 possible 均可作表语，但possible可以用不定式作真实主语， 而probable不能用不定式作真实主语。

It is probable for him to come to the meeting.(错)

It is possible for him to come to the meeting.

It is possible / probable that he will come to the meeting.

二、不定式做表语

主语是以aim duty hope idea intention plan job suggestion wish purpose task 等为中心词的名词词组 或以 what 引导的名词性从句表示，后面的不定式说明其内容, 不定式作表语常表示将来或现在的动作或状态。

eg :My idea is to climb the mountain from the north.

Your mistake was not to write that letter.

What I would suggest is to start work at once.

三 、动词不定式作宾语

以不定式结构为宾语的动词有：

ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用动词不定式作宾语

口诀(接不定式作宾语的动词)

想要学习 早打算( want learn plan)

快准备 有希望( prepare hope wish expect)

同意否 供选择(agree offer choose)

决定了 已答应(decide be determined promise)

尽力去 着手做(manage undertake)

别拒绝 别假装(refuse pretend)

失败不是属于你(fail)

e.g.Tom refused to lend me his pen.

We hope to get there before dark.

Ⅰ、状语从句中的省略用法

以if从句为代表的状语从句中的特殊省略用法：通常省略了it is，that is，there is/are。

Ⅱ、定语从句中的省略用法

关系词的省略 关系代词that，which，whom等在限制性定语从句中充当宾语且不位于介词之后时，可以省略;in which或that在先行词way后作方式状语从句时可省略。

Ⅲ、虚拟语气中if及should的省略

1、 当条件状语从句中有were，had，should等时省略if，把它们提至句首，形成倒装句。

2、 Suggest，insist，order，require等表示建议、要求、命令的动词后接的名词性从句中，谓语动词常用“should+动词原形”，should可以省略。

Ⅳ、不定式符号to的省略

1、 感官动词see，hear，feel，watch等和使役动词have，make，let等后接不定式作宾语时，不定式省略to。

2、 在特定语境中为了避免重复，当不定式再次出现时，在want，wish，hope，try，plan，like，love，hate后往往只保留to，而省略后面的动词。但不定式后有be，have时，也保留be和have。

Ⅴ、So和not的替代性省略

用于避免重复前面所说过的内容，替代词so/not替代肯定或否定的名词性从句。可与believe，do，expect，fear，guess，hope，say，speak，suppose，think，I’m afraid等连用

一、过去分词

过去分词兼有动词、副词和形容词的特征，可以带宾语或受状语修饰。过去分词和宾语或状语一起构成过去分词短语。它在句中可以作定语、表语、宾语补足语或状语。这节课讲解作定语、表语的用法。

1. 作定语

作定语的过去分词如果是单词，一般放在被修饰词的前面;过去分词短语作定语，一般放在被修饰词的后面。例如：

There are many fallen leaves on the ground.

This is a book written by a worker.

2. 作表语

过去分词作表语,多表示主语所处的状态。

I was pleased at the news.

The door remained locked.

过去分词作表语，相当于形容词，常见的有：delighted, disappointed, astonished, interested, satisfied, surprised, tired, worried, excited, married 等。

过去分词作表语时，应注意与被动结构的区别。系表结构说明主语的状态或具有的性质、特点;被动结构强调谓语动作。

The small village is surrounded by trees.(状态)

The small village was soon surrounded by enemy soldiers.(动作)

I'm interested in chess.(状态)

3. 过去分词做状语

①表时间，相当于一个时间状语从句，有时过去分词前可加连词 when 或 while 来强调时间概念。

een from the top of the hill, the city looked like a big garden.

Accepted by the Party, he decided to devote his life to the cause of the Party.

②表原因，相当于一个原因状语从句。

Exhausted, the children fell asleep at once.

Encouraged by the speech, the young people made up their minds to take up the struggle.

③表条件，相当于一个条件状语从句，有时过去分词前可用 if 等词

Heated, water changes into steam.

Given another chance, he will do better.

④表让步，相当于一个though/although引导的让步状语从句。

Laughed at by many people, he continued his study.

⑤表伴随，说明动作发生的背景或情况。

urrounded by a group of pupils, the old teacher walked into the classroom.

The trainer appeared, followed by five little dogs.

倒装句：

一、here, there, now, then, thus 等副词置于句首, 谓语动词常用 be, come, go, lie, run。

There goes the bell. 铃声响了。

Then came the chairman. _来了。

Here is your letter. 你的信。

二、否定词置于句首，句子应进行倒装。 neither 放句首

Tod can't swim, neither can I. 托德不会游泳，我也不会。

用于 never, hardly, seldom, scarcely, barely, little, often, at no time, not only, not once, many a time 等词开头的句子。

ever shall I go there again. 我再也不去那了。

Little did he know who the woman was.他基本上不知道那女人是谁。

eldom was he late for class.他很少上学迟到。

用于 no sooner ... than ..., hardly... when... 和 not until... 的句型中

o sooner had she gone out than the phone rang. 她刚离开,电话就响了。

ot until the teacher came did he finish his homework. 直到老师来，他才完成作业。

三、用于 only 放句首，修饰副词、介词短语或状语从句的句子。

Only in this way can you master English well. 只有这种方法，你才能学好英语。

Only that time did he do his homework. 直到哪个时间，他才做作业。

Only when he told me did I realize what trouble I was in.

省略句：

一、省略的目的

省略多见于非正式文体，尤其在对话中，省略是一种普遍的现象。英语中的省略一般说来有三个目的：

1.避免重复，减少累赘。省略的主要目的是避免重复，去掉不必要的累赘和繁琐。

Mike said that he would come to school to see me the next day, but he didn't come to school to see me the next day.

Mike said that he would come to school to see me the next day, but he didn't.

(省掉最后九个词，句子简洁了许多)

2.连接紧密，结构紧凑 省略也是使上下文紧密连接的一种修辞手段。

John was the winner in 1994 and Bob in 1998.(Bob 后省略了 was the winner，句子结构显得比较紧凑)

3.强调重点，突出信息 省略的另一作用是突出新的信息

Truth speaks too low, hypocrisy too loud.后一分句省略谓语 speaks，突出了 too loud)
