英语语法知识难点（一）
（一） 形容词和副词
I． 要点
A． 形容词
1、 形容词的用法
形容词是用来修饰、描绘名词的，通常在句中作定语、表语或宾补，有时还可作状语。：
He is honest and hardworking.
I found the book interesting.
某些形容词与定冠词连用表示一类人作主语时，谓语通常用复数形式。如：
The rich and the poor live in different parts of the city.
The English like to be with their families.
多个形容词作定语修饰名词的顺序：
冠词+序数词+基数词+性质状态（描述性）+形状大小+新旧老少+颜色+国籍+材料+名词。如：
the second five interesting big new red Chinese wall papers.
2、 形容词比较等级的形式
（1） 规则形式
一般说来，单音节词及少数双音节词在后加-er; --est 来构成比较级和最高级；其他双音节词及多音节词在前加more, most.如：
great-greater-greatest
busy-busier-busiest
important-more important-(the)most important
（2） 不规则形式
good (well)-better-best
bad (ill)-worse-worst
many (much)-more-most
little-less-least
（3） 形容词比较等级的用法
①表示两者的比较，用形容词的比较级+than. 如：
He is cleverer than the other boys.
This one is more beautiful than that one.
②表示两者以上的比较，用"the +形容词最高级（+名词）+of(in) …"如：
He is the cleverest boy in his class.
③表示两者是同等程度，用"as +形容词原级+as". 如：
He is as tall as I.
I have as many books as you.
④ 越… 越…
例如：The more I learn, the happier I am.
⑤ You can never be too careful. 越小心越好
又如：You can never praise the teacher too highly.
你怎么赞扬这个老师也不过分。
⑥ I have never spent a more worrying day.
那一天是最令我担心的一天。
I have never had a better dinner.
这是我吃过的最好的一顿饭。
⑦ My English is no better than yours.

3、 某些副词在用法上的区别
（1） already, yet, still
already表示某事物已经发生，主要用于肯定句；yet表示期待某事发生，主要用于否定句和疑问句；still表示某事还在进行，主要用于肯定句和疑问句，有时也可用于否定句。如：

（2） too, as well, also, either
too, as well和 also用于肯定句和疑问句，too和as well多用于口语，一般放在句末，而also多用于书面语，一般放在句中与动词连用。either用于否定句和否定的疑问句，往往放在句末。如：

He didn't go there either.
I like you as well.
I also went there.
(3) hard, hardly
hardly意为"几乎"与hard在词义上完全不同。如：

解析：A、B两项except等于but，意为"除了…"，C-beside意为"在…旁边"，不符合题意。而D-besides, 意为"除了…之外，还有"。所以该题正确答案为D。该题意为：除了英语外，你还知道别的语言吗？
例2 He suddenly returned ____ a rainy night.
A on B at C in D during

（六）短语动词
I． 要点
英语中有许多短语动词在意义上是一个整体，其用法有的相当于及物动词，有的相当于不及物动词，有的兼有及物动词和不及物动词的特征。英语短语动词的构成主要有以下六种：
（1） 动词＋介词
常见的有look for, look after, send for, care about, ask for, laugh at, hear of (from), add to, lead to等。这类短语动词的宾语只能放在介词后。如：
Don't laugh at others.
I didn't care about it.
（2） 动词＋副词
常见的有give up, pick up, think over, find out, hand in, point out等。这类短语动词的宾语如果是名词，既可放在副词前边，又可放在副词后边；宾语如果是人称代词或反身代词，则要放在副词前边。如：
You'll hand in your homework tomorrow.
Please don't forget to hand it in.
（3） 动词＋副词＋介词
常见的有look down upon, go on with, break away from, add up to, catch up with等。这类短语动词的宾语只能放在介词后边。如：

常见的有take care of, make use of, pay attention to, make fun of 等。这类短语动词的宾语只能放在介词后边。如：
You should pay attention to your handwriting.
We should make full use of our time.
（5） 动词＋形容词
常见的有leave open, set free, cut open等。这类短语动词的宾语如果是名词，则宾语可放在形容词的前边，也可放在后边；宾语如果是人称代词或反身代词，则必须放在形容词前边。如：
The prisoners were set free.
He cut it open.
（6） 动词＋名词
常见的有take place, make friends等。这类短语动词用作不及物动词。如：
This story took place three years ago.
I make friends with a lot of people.
（7）辨析
give away(让给，暴露)和 give up（放弃，停止）
put away（放起，收起）和 put out （扑灭）
turn up（出席，放大）和 turn on （打开）
keep out（阻止）和 keep off （不让靠近）
make up（编造，补上）和 make out（辨认）

A Look out B Look around C Look forward D Look on
解析：该题选A. look out 意为"小心"。
（七）动词不定式
I． 要点
1、 不定式的形式。以动词write为例。
2、 不定式的句法功能
（1） 作主语
To hear from you is nice.
To be a good teacher is not easy.
不定式作主语时，为了保持句子的平衡，往往以it作形式主语，而不定式置于谓语动词后。如：
It's nice to hear from you.
It's not easy to be a good teacher.
（2） 作宾语
通常用于want, hope, wish, like, need, hate, begin, start, remember, agree, learn, pretend, refuse, manage, help等词后。如：
I forgot to lock the door.
Please remember to write to me.
（3） 作表语
My job is to pick up letters.
He seemed to have heard nothing.
（4） 作定语
不定式作定语时，须放在它所修饰的名词或代词后。如：
I have two letters to write.
I have a lot of work to do.
（5） 作宾补
通常用于want, wish, ask, order, tell, know, help, advise, allow, cause, force等词后。如：

He seemed to have cleaned the room before I came in.
The boy is said to have been sent to the hospital last week.
（11）too…to 结构。如：
He was too excited to go to sleep.
He was only too glad to go. (他太高兴了，乐意去)
（12）主动表被动。如：
The book is easy to read.
I have a book to read.
II．例题
例1 I haven't got a chair ____.
A to sit B for to sit on C to sit on D for sitting
解析：该题选C。不定式to sit on在句中作定语，修饰名词chair. 因为不定式和它所修饰的名词间是"动宾关系"，所以不定式必须是及物动词，故此处on不能省略。
例2 He was made ____.
A go B gone C going D to go
解析：该题选D。make sb. do sth. 如果是被动形式，不定式do前的to不能省略。
例3 A new factory is ____ very soon.
A to be built B built
C to build D to building
解析：该题选A。is to be built意为"将要被建"。
（八）动名词
I． 要点
动名词既具有动词的一些特征，又具有名词的句法功能。
1、 动名词的形式，以write为例。
否定式 not +动名词
2、 动名词的用法
（1） 作主语
Playing football is my favorite sport.
Travelling with friends at weekend is fun.
作主语的动名词结构复杂且长时，可用it作形式主语。如：
It is fun travelling with friends at weekend.
（2） 作宾语
I enjoy playing PC game.
He gave up writing five years ago.
（3） 作表语
What he hated most was doing nothing.
Seeing is believing.
动名词作表语时，句子的主语常是无生命名词或what引导的名词性从句。
（4） 作定语
There's a dining room in my school.
All the people watching laughed.
（5） 动名词的复合结构"物主代词（或名词的所有格）+动名词"。如：
Tom's going home late made her mother angry.
Would you mind my opening the window?
不过，动名词的逻辑主语在遇到以下情况时，必须用名词的普通格（或人称代词的宾格）。
①无生命名词
The girls were afraid of the door suddenly closing.
Fire burns better by oxygen being at work.
②有生命名词，但表泛指。
Have you ever heard of girls smoking?
③两个以上的有生命的名词并列。
Do you still remember my parents and me coming to see you that day?
3．后面常接动名词的动词和短语
mind, enjoy, finish, consider, practise, magine,
keep, suggest, advise, allow, permit,
be worth doing, be used to doing, be busy doing,
can't help doing, it is no good doing, it is no use doing,
look forward to doing, stick to doing, pay attention to doing,
devote to doing, lead to doing
II．例题
例1 She says she doesn't feel like ____ out with you.
A going B to go C for going D went
解析：该题正确答案为A。 feel like = want, 此处like 为介词，后面要接名词或动名词作宾语
例2 The garden needs ____.
A water B watering C to water D watered
解析：该题正确答案为B。 need = want = require. 如果物作主语，此三者后要接动名词或to be done这一结构作宾语。
例3 Excuse me ____ you.
A interrupting B to interrupt
C interrupted D to have interrupted
解析：该题正确答案为A。excuse 后接动名词作宾语，此句中的me为动名词的逻辑主语（常用于口语中）。
（九）分词
I． 要点
分词既具有动词的一些特征，又具有形容和副词的句法功能。它分为现在分词和过去分词两类。现在分词和过去分词的主要差别在于现在分词有一般式和完成式，过去分词则只有一般式。现在分词表动作正在进行，表主动。过去分词及物动词表动作已经完成，表被动。过去分词不及物动词表动作已经完成，表主动。

11. 动词的时态

11.1 一般现在时的用法

1） 经常性或习惯性的动作，常与表示频腮度的时间状语连用。时间状语： every…, sometimes, at…, on Sunday。例如：

2） 客观真理，客观存在，科学事实。例如：

The earth moves around the sun. 地球绕太阳转动。

Shanghai lies in the east of China. 上海位于中国东部。

3） 表示格言或警句。例如：

注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。

例：Columbus proved that the earth is round. 哥伦布证实了地球是圆的。

4） 现在时刻的状态、能力、性格、个性。例如：

I don't want so much. 我不要那么多。

Ann writes good English but does not speak well. 安英语写得不错，讲的可不行。

比较：Now I put the sugar in the cup. 把糖放入杯子。

I am doing my homework now. 我正在做功课。

第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。

Christine has been an invalid all her life.（含义：她现在还活着）

Mrs. Darby lived in Kentucky for seven years. （含义：达比太太已不再住在肯塔基州。）

Mrs. Darby has lived in Kentucky for seven years. （含义：现在还住在肯塔基州，有可能指刚离去）

注意： 用过去时表示现在，表示委婉语气。

1）动词want, hope, wonder, think, intend 等。例如：

Did you want anything else? 您还要些什么吗？

I wondered if you could help me. 能不能帮我一下。

2）情态动词 could, would。例如：

11.10 比较一般过去时与现在完成时

1）一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。

2）一般过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。

一般过去时的时间状语：yesterday, last week，…ago, in1980, in October, just now等，皆为具体的时间状语。

现在完成时的时间状语：for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等，皆不确定的时间状语。

共同的时间状语：this morning, tonight, this April, now, already, recently, lately 等。

3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know.。

一般过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。例如：

I saw this film yesterday. （强调看的动作发生过了）

I have seen this film. （强调对现在的影响，电影的内容已经知道了）

Why did you get up so early? （强调起床的动作已发生过了）

Who hasn't handed in his paper? （强调有卷子未交，疑为不公平竞争）

He has been in the League for three years. （在团内的状态可延续）

He has been a League member for three years. （是团员的状态可持续）

句子中如有过去时的时间副词（如yesterday, last, week, in 1960）时，不能使用现在完成时，要用过去时。

（错）Tom has written a letter to his parents last night.

（对）Tom wrote a letter to his parents last night.

11.11 用于现在完成时的句型

1）It is the first / second time.... that…结构中的从句部分，用现在完成时。例如：

It is the first time that I have visited the city. 这是我第一次访问这城市。

This is the first time （that） I've heard him sing. 这是我第一次听他唱歌。

注意：It was the third time that the boy had been late.

2）This is +形容词最高级+that…结构，that 从句要用现在完成时。例如：

This is the best film that I've （ever） seen. 这是我看过的最好的电影。

典型例题

（1） ---Do you know our town at all?

---No, this is the first time I ___ here.

A. was B. have been C. came D. am coming

答案B. This is the first time 后面所加从句应为现在完成时，故选B。

（2） ---Have you ____ been to our town before?

---No, it's the first time I ___ here.

A. even, come B. even, have come C. ever, come D. ever, have come

答案D. ever意为曾经或无论何时，反意词为never，此两词常用于完成时。

注意：非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。

（错）I have received his letter for a month.

（对）I haven't received his letter for almost a month.

11.12 比较since和for

Since 用来说明动作起始时间，for用来说明动作延续时间长度。例如：
I have lived here for more than twenty years.我住在这儿二十多年了。
I have lived here since I was born. 我从出生起就住在这儿了。
注意：并非有for 作为时间状语的句子都用现在完成时。
I worked here for more than twenty years. （我现在已不在这里工作。）
I have worked here for many years.（现在我仍在这里工作。）
注意：用句型转换的方法，很容易排除非延续动词在有for/since结构的完成时中的误用。
1）（对） Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2）（错） Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
显然，第二句不对，它应改为 Harry got married six years ago. 或 Harry has been married for six years.

11.13 since的四种用法

1） since +过去一个时间点（如具体的年、月、日期、钟点、1980, last month, half past six）。例如：

I have been here since 1989. 1989起，我一直在这儿。

2） since +一段时间+ ago。例如：

I have been here since five months ago. 我在这儿，已经有五个月了。

3） since +从句。例如：

Great changes have taken place since you left. 你走后，变化可大了。

Great changes have taken place since we were here. 我们走后，变化可大了。

4） It is +一段时间+ since从句。例如：

It is two years since I became a postgraduate student. 我考上研究生有两年了。

11.14 延续动词与瞬间动词

1） 用于完成时的区别

延续动词表示经验、经历； 瞬间动词表示行为的结果，不能与表示段的时间状语连用。例如：

He has completed the work. 他已完成了那项工作。 （表结果）

I've known him since then. 我从那时起就认识他了。（表经历）

2） 用于till / until从句的差异

延续动词用于肯定句，表示"做……直到……" 瞬间动词用于否定句，表示"到……，才……"。例如：

He didn't come back until ten o'clock. 他到10 点才回来。

He slept until ten o'clock. 他一直睡到10点。

典型例题

1. You don't need to describe her. I ___ her several times.

A. had met B. have met C. met D. meet

答案B. 首先本题后句强调对现在的影响，我知道她的模样，你不用描述。再次，several times告知为反复发生的动作，因此用现在完成时。

2. ---I'm sorry to keep you waiting.

---Oh, not at all. I ___ here only a few minutes.

A. have been B. had been C. was D. will be

答案A. 等待的动作由过去开始，持续到现在，应用现在完成时。

11.15 过去完成时

1） 概念：表示过去的过去

----|----------|--------|----> 其构成是had +过去分词构成。

那时以前 那时 现在

2） 用法

a. 在told, said, knew, heard, thought等动词后的宾语从句。例如：

She said （that）she had never been to Paris. 她告诉我她曾去过巴黎。

b. 状语从句

在过去不同时间发生的两个动作中，发生在先，用过去完成时；发生在后，用一般过去时。例如：

When the police arrived, the thieves had run away. 警察到达时，小偷们早就跑了。

c. 表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本…，未能…"。例如：

We had hoped that you would come, but you didn't. 那时我们希望你能来，但是你没有来。

3） 过去完成时的时间状语before, by, until , when, after, once, as soon as。例如：

He said that he had learned some English before. 他说过他以前学过一些英语。

By the time he was twelve, Edison had began to make a living by himself. 到了十二岁那年，爱迪生开始自己谋生。

Tom was disappointed that most of the guests had left when he arrived at the party.

汤姆失望了，因为他到达晚会时，大部分客人已经走了。

典型例题

The students ___ busily when Miss Brown went to get a book she ___ in the office.

A. had written, left B，were writing, has left C. had written, had left D. were writing, had left

答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前，因此"忘了书"这一动作发生在过去的过去，用过去完成时。句中when表示的是时间的一点，表示在"同学们正忙于……"这一背景下，when所引导的动作发生。因此前一句应用过去进行时。

注意： had hardly… when 还没等…… 就……。例如：

I had hardly opened the door when I he hit me. 我刚打开门，他就打了我。

had no sooner…than 刚…… 就……。例如：

He had no sooner bought the car than he sold it. 他刚买了这辆车，转眼又卖了。

When she saw the mouse，she screamed. 她看到老鼠，就叫了起来。

My aunt gave me a hat and I lost it. 姑妈给了我一顶帽子，我把它丢了。

2 ） 两个动作相继发生，可用一般过去时；如第一个动作需要若干时间完成，用过去完成时。例如：

3） 叙述历史事实，可不用过去完成时，而只用一般过去时。例如：

A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.

答案D. 前句是一个仍在持续的状态，应用进行时，由于没有找到，其影响仍然存在，应用完成时，瞬间动词用于否定式时可用于完成时。
