专业英语四级备考冲刺之语法重点总结
一代数名词数词
1 在使用两个以上的人称代词时顺序是:第二人称第三人称第一人称
2 everyone后面不可以跟of短语every one 就可以
3 以‘名词/动名词+介词（短语）/形容词/副词/动词不定式’构成的复合名词，它的复数形式是将作为主要部分的名词或动名词变为复数直接来源于短语或以可数名词结尾的复合名词的复数形式是将最后一个构词部分变为复数以‘man 或者woman+名词’构成的复合名词的复数形式是将两个组成部分全变成复数以不可数名词结尾的复合名词无复数形式如：homework
4 物质名词一般不可数，但用于表示‘各种不同品种’时几乎都可做可数名词如：different teas
5 当抽象名词前后有修饰语表示‘某一种’或‘某一方面’的抽象概念时其前可加a/an
6 名词所有格要点：
必须用’s的场合
1) ’s属格用于表示时间，度量衡，价值的名词之后
2) 作为一个整体的词组在最后一个词加’s , 人或物为两人共有，在第二个名词后加’s, 复合名词在最后一个词后加’s
3)当所有格后面的名词是人们熟悉的建筑物, 如商店，住家，教堂，医院等，常省略
当被修饰的名词后有同位语时，必须用’s 当用来表示类别或属性时，要用’s children’s shoes
必须用of的场合
1) 名词后跟有后置修饰语或同位语时 2) 以定冠词加分词或形容词表示一类人时
7 如果dozen/score/hundred/thousand/million前有基数词以表示确切数目时，都不能用复数形式如果用来表示很多有不确切的数目时，须用复数，而且后面加of
8 表示顺序的两种方式：
1‘名词+基数词’，不用冠词，如Chapter four 2 ’the+序数词+名词‘如the Fourth Chapter
9倍数增减的表示法
1倍数+形容词/副词比较级+than 2倍数+as+形容词/副词+as3倍数+名词4动词+百分比或倍数5动词+to+数词6double/triple/quadruple+名词7动词+by+数词/百分比/倍数
10分数分子为基数词，分母为序数词分母除了在分子为一的其他情况下为复数
11百分比后接名词时加of
二形容词副词
1．前置修饰语的排列顺序
冠词前的形容词（all both such) -----冠词，指示形容词，所有格形容词，不定形容词（a an the this your his any some)----基数词（one ) 序数词（first)---- 表示性质，状态，质量的形容词（good useful)----表示大小，
／necessary／important／urgent／imperative／desirable／
advisable／ natural／ essential＋that＋动词原形；It is time／about time
／high time＋that＋一般过去时：proposal／suggestion＋that＋动词原形；
lest＋that＋should＋动词原形；if only＋that＋would＋动词原形。

2）状语从句的考点为：非if引导的条件状语从句，此类句子多用at times，
provided，so long as，in case，once等来替代if；由even if／so，now that，
for all等引导的让步状语从句；just／hardly...when引导的时间状语从
句；more than，as...as，not so much as，the same as，as much as等引导
的比较状语从句。

3）独立主格结构多以逻辑主语＋分词的形式出现。

4）情态动词多与完成时形式连用。

5）定语从句重点考查介词＋关系代词（which）和as作为关系代词。

1）．动词、名词与介词的搭配如：popular／patient＋with；yield／solution／adapt／transfer／access＋to；accuse／require＋of；charge＋for；under＋discussion等等。

2）．习惯用法如：confess to／set about／be used to＋doing；be supposed to／have／make sb．＋do等。

3）．由同一动词构成的短语如：come，go，set，break等构成的短语。

4）．单个的动词，抽象名词，形容词和副词多以近义词、同义词的形式出现。

5）．介词短语在句中作状语如：in terms of；with the exception of；in vain等，另外还应注意rather than，other than，such as，none／nothing＋but等词在考题中的出现。

1）不可数名词的量化表示
修饰可数名词复数: many, a good/great many，a good/great/large number of
修饰不可数名词: much, a great deal of, a large amount of
两者都可修饰: a lot of, lots of, plenty of, a great/large quantity of,
quantities of, a large sum of
2）在汉语中可数，但在英语中为不可数名词的某些词
advice, baggage (luggage), damage, equipment, furniture, homework,
information, news ...
5) –thing代词
something of 若干、多少、有些anything but 并不，根本不nothing but 只
不过，只有something like 有点像or something 类似
Mr. Smith is an engineer or something.
She is nothing but a dancer.
He was anything but pleased when he heard this.
1) 修饰词的词序
“限定词+形容词+名词”词组中限定词+形容词的排列顺序。

限定词 + 一般描述性形容词 + 表示大小、形状的形容词 + 表示年龄、新旧的形容词 + 表示颜色的形容词 + 表示国籍、地区、出处的形
容词 + 表示物质材料的形容词 + 表示用途、类别的形容词或名词1) So,
such
So +adj. + a +noun.
Such +a+adj. +noun.
1)by/between/up to/till +过去时间、since、by the time/when +表示过去
发生情况的从句，主句用过去完成时。

将来完成时。

(3)by now、since +过去时间、in/during/for/over/the past/last few(或具
体数字)years/days/months，主句用现在完成时, 但在it is +具体时间since/before这一句型中，主句更多的时候不用完成时。

如：

在完成时。

成时。

3) 完成进行时指动作在完成时的基础上还要继续下去。

如：

8. 动名词
1) 必须接动名词做宾语的动词

(for there to be…在句中做目的状语) It isn’t cold enough for the
4) 常用虚拟形式的句型

though suppose…
had rather would sooner as
if supposing…
If only… It is (high) time that…(从句中
动词只用过去式)
(4)lest/for fear that/in case 从句谓语用(should+)动词原形
(5)5)whether…or…有时谓语用be的原形，引导让步虚拟从句，这种用法经常采用倒装结
2) 表示虚拟语气

如：

注意这个句型的变
体cannot…over…。

如：
