高三英语知识点总结1
It的用法
1、It除了代替人和物以外,还可以作形式主语.而真正的主语(不定式、动名词或从句)则放于谓语或表语之后.
例如：It is nor easy to finish the work in two days.
然而有少数表语之后接动名词作真正的主语.这些表语是：无助(no help)、无用(no use)、没好处(no good);工作(hard work)、费时(a waste of time)、又危险(a danger).
例如：A、It is no use crying over spilt milk.
B、It is a waste of time waiting for him.
2、It还可以作形式宾语.通常下列动词后面可接it作形式宾语：2f2tcjm(find,feel,think,take,consider,judge, make).
例如：A、He made it clear that he was not interested in this subject.
B、I think it no use arguing with him.
3、It用于强调句式.要强调句子的某一部分(主语、宾语、 状语),可以把it当作先行词.这种句子的结构是：It is(was)+ 被强调部分+that(who)+句子的其余部分.
例如：A、It iS Professor Lin who teaches us English—(强调主语)
B、It was in Shanghai that l saw the film.—(强调状语)
C、It was in 1990 that I worked in the factory.(同上)
但要注意与定语从句的区别.
例如：D、It was 1990 when I worked in the factory.(定语从句)
在强调句式里,我们把强调结构It is(was)…that除去,句子还很完整.如例句C.而例句D就不能.
倒装结构
学生容易混淆的是全部倒装与部分倒装.如何区分之,编个顺口溜：副(adv.)介(prep.)提前全倒装,其它句式部分倒;否定提前倒助动,让步状语倒表语;复合句式倒主句,不
倒装的属特殊.下面举例说明：
A、Here comes the bus.(副词提前,全倒装)
B、Here he comes.(代词作主语,不倒装)
C、In front of the house lies a garden.(介词短语提前,全倒装)
D、Never shall I do this again.(否定词提前,部分倒装)
E、Young as he is ,he knows a lot.(让步状语从句,表语倒装)
F、Only when he told me did I realize what trouble he was in.(only 修饰状语,主句倒装)
G、Only he can save the patient.(only修饰主语.不倒装)
H、Not only will help be given to people,but also medical treatment will be provided.(否定词提前,部分倒装)
I、Not only he but also we like sports.(连接两个主语,不倒装)

一、就近一致原则
1.由or，not only...but also...，neither...nor...，either...or...，whether...or...，not...but...等连接两个或两个以上的并列主语时，通常根据就近一致原则，谓语动词要与离它最近的主语在数上保持一致。
Neither his parents nor I am able to persuade him to change his mind.
2.here/there引导一个句子而主语又不止一个时，通常根据就近原则，谓语动词要与离它最近的主语在数上保持一致。
Here is a ruler，a few pencils and two copybooks.
二、意义一致原则
1.谓语动词必须用单数的情况
(1)表示学科的名词以及works(工厂)，news(消息)等作主语时，虽然本身为复数形式，但表示单数意义时，谓语动词仍用单数。
Politics is his favorite subject.
(2)表示某些组织机构的名词、书/报名、国名、地名等作主语时，虽然形式上是复数，但所表示的意义是单数，所以谓语动词用单数。
Do you know when the United Nations was set up?
2.谓语动词必须用复数的情况
表示总称意义的名词，如people，police，public，cattle等作主语时，谓语动词用复数。
The police are searching for the murderer.
3.谓语动词的形式依据主语表示的意义而定
(1)集体名词，如family，class，group，team，club，company，government，population等作主语时，谓语动词的形式根据其在语境中表示的意义而定。当其表示集体意义，强调整体概念时，谓语动词用单数;当其表示集体中各个组成部分，强调个体概念时，谓语动词用复数。
As far as I know，his family is not very large but the family are all music lovers.
(2)“the+形容词/分词”表示“一类人”时，谓语动词用复数。
The poor were looked down upon in the old days.
三、语法一致原则
1.由and连接的两个名词作主语
(1)“a/the+名词单数+and+名词单数”表示一个人(双重身份)，谓语动词用单数。
The teacher and poet often gives lectures around the city.
(2)“a/the+名词单数+and+a/the+名词单数”表示两个人，谓语动词用复数。
The teacher and the poet have just arrived.
(3)“every+名词单数+and+every+名词单数”表示每一个人，谓语动词用单数。
Every boy and every girl has the right to receive education in our country.
(4)通常由两个部件组成的物品如：a knife and fork (一副刀叉)等作主语，谓语动词用单数。
Bread and butter is not to his taste.
2.表示时间、数量、长度及价格的名词，尽管有时是复数形式但常被看作是一个整体，谓语动词用单数形式。
Is fifty pounds enough?
3.“分数/百分数+of+名词”作主语时，谓语动词的形式根据of后的名词的形式来定，如果名词是可数名词复数，谓语动词用复数形式;如果名词是单数可数名词或不可数名词，谓语动词用单数形式。
Two-thirds of the books are about science.
Only 30% of the work was done yesterday.

高三英语知识点总结5
look at a book?
1. 表示阅读性地“看书”(即读书)，一般要用动词 read。如：
Don’t read such books. 不要读那样的书。
He is reading a book on Shakespeare. 他在看一本关于莎士比亚的书。
但是，在许多情况下，“看书”只需用read 就够了(尤其是泛泛地表示“看书”时)，无需后接book作宾语。如：
In the evening I usually read. 晚上我常常看书。
This light is too poor to read by. 这光线太暗不能看书。
I read much less now than I did at school. 我现在看书远比我上学时少。
2. 若不是表示阅读性地“看书”，而只是大概地看一看，比如看看书的封面、定价、内容提要等，或者回答问题时看看书的某些章节或字句等，或者是考试时悼词楸镜龋此时都不宜用动词read, 可用look at, see 等。如：
Can I look at those books? 我可以看看那些书吗?
Jim demanded to see my books. 吉姆要求看看我的书。
Please answer my questions without looking at your books. 请不看书回答我的问题。
Students must not look at their books during examinations. 学生考试不准舞弊。
