（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。如：
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.
我的英语和你的英语都不怎么样。
B．副词
1、 副词的种类
（1） 时间副词 如：ago, before, already, just, now, early, late, finally, tomorrow等
（2） 地点副词 如：here, there, near, around, in, out, up, down, back, away, outside等。
（3） 方式副词 如：carefully, angrily, badly, calmly, loudly, quickly, politely, nervously等。
（4） 程度副词 如：almost, nearly, much, greatly, a bit, a little, hardly, so, very等。
2、 副词比较等级的用法
其用法与形容词相似，只是副词最高级前可省略定冠词。如：
Of all the boys he sings (the) most beautifully.
We must work harder.
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：
We've already watched that film.
I haven't finished my homework yet.
He still works until late every night.
（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 went there too.
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：
I work hard every day.
I can hardly remember that.
(4) late, lately
lately意为"最近、近来"，late意为"晚、迟"。如：
He never comes late.
Have you been to the museum lately?
II． 例题
例1 Tom's father thinks he is already ____
A high enough B tall enough
C enough high C enough tall
解析：该题正确答案是B。修饰人高用tall, 而建筑物的高用high,并且enough修饰形容词要放在形容词后面。因此该题选B。
例2 ____ the worse I seem to be.
A When I take more medicine
B The more medicine I take
C Taking more of the medicine
D More medicine taken
解析：该题正确答案为B。"the+形容词比较级+… , the +形容词比较级+…"意为越…，越…。该句意为：吃的药越多，我的病越是加重。
例3"I haven't been to London yet".
"I haven't been there ____".
A too B also C either D neither
解析：该题正确答案为C。A和B都用于肯定句中。D-neither本身意为否定"两者都不"，而C-either则用于否定句中，意为"也"。
例4 Mr Smith was ____ moved at the news.
A deep B deeply C very deep D quite deeply
解析：该题正确答案为B。A. deep用于副词时，修饰具体的深，如dig deep,而B-deeply则修饰表示感情色彩的词，如该题为deeply moved.另如deeply regret等。而D-quite和deeply均为副词，不能互相修饰。

He came right after dinner.
He lives directly opposite the school.
4、 某些介词的意义与用法举例
（1） at, on, in（表时间）

II． 例题
例1 Do you know any other foreign language____ English?
A except B but C beside D besides
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
解析：我们均知道，at night这一短语，但如果night前有修饰词，表具体的夜晚，则要用介词on来修饰，故该题正确答案为A。
例3 I'm looking forward ____your letter.

II．例题
例1 I learned that her father ____ in 1950.
A had died B died C dead D is dead
解析：该题正确答案为B。从句中的谓语动词动作虽然发生在主句谓语动词的动作之前，但因从句中有明确的过去时间状语in 1950, 所以不用过去完成时态，而用一般过去时态。
例2 The five-year-old girl ____ by her parents.
A is looked B has looked for
C is being looked for D has been looked
解析：该题正确答案为C。在带有介词的动词短语用于被动语态句中，介词不能省，否则就变成了不及物动词短语，而不能用于被动语态的句子中。
（五）动词虚拟语气
I． 要点
表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或与事实相反的假设等。一般常用于正式的书面语中。
1、 虚拟语气的构成
情景 条件从句的谓语动词 主句的谓语动词
与现在事实相反 动词过去式 （be要用were） should ????????
+动词原形
would
与过去事实相反 had +过去分词 should ????????
+have+过去分词
would
与将来事实相反 1、动词过去时
2、should +动词原形
3、were to +动词原形 should ????????
＋动词原形
would
注：如果条件从句谓语动词包含有were或had, should, could有时可将if省去, 但要倒装。如：
Had you (If you had) invited us, we would have come to your party.
2、 虚拟语气在各种从句的应用
（1） 在主语从句中用来表示惊奇、惋惜、理应如此等，其谓语形式是"should(可省) ＋动词原形"，常用于以下三种句型中。
句型一：It is necessary (important, natural, strange, etc) that…
句型二：It is a pity (a shame, no wonder, etc) that…
句型三：It is suggested (requested, proposed, desired, etc) that…
如： It is strange that he (should) have done that.
It is a pity that he (should) be so careless.
It is requested that we (should) be so careless.
（2） 在宾语从句中用于suggest, propose, move, insist, desire, demand, request, order, command等动词后的宾语从句中，表间接的命令和建议。其谓语形式是"(should)+动词原形"。如：
I suggest that we (should) go swimming.
（3） 在表语从句中，表示间接的命令，要求、请求、建议、决定等，主句中的主语通常是suggestion, proposal, request, orders, idea等。从句谓语形式是"(should)＋动词原形"。如：
His suggestion is that we (should) leave at once.
（4） 在同位语从句中，谓语形式是"(should)＋动词原形"。如：
We received order that the work be done at once.
（5） 在It is time that…句型中，其谓语动词形式是"动词的过去式"或
"should ＋动词原形",should不可省。如：
It's time (that) we went ( should go) to school.
II． 例题
例1 We had hoped that he ____ longer.
A stays B have stayed C stayed D would stay
解析：该题正确答案为D。had hoped表示"本希望"，同样用法的动词还有think, expect等，后面的句子需用虚拟语气
例2 "Mary wants to see you today".
"I would rather she ____ tomorrow than today."
A comes B came C should come D will come
解析：该题正确答案为B。would rather后面的从句需用虚拟语气，用动词过去时表示。
例3 Had she been older, she ____ it better.
A had done B might have done
C might do D would do
解析：Had she been older = If she had been old. 故该题正确答案为B。
（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：
All his money added up to no more than $100.
After a short rest, he went on with his research work.
（4） 动词＋名词＋介词
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）
take off（脱，起飞） 和 take out（拿出）
II． 例题
例1 It is wise to have some money ____ for old age.
A put away B kept up C given away D laid up
解析：该题正确答案为A。意为"存"；keep up意为"继续"；give away意为"分发"；lay up"贮藏"。
例2 Here's my card. Let's keep in ____.
A touch B relation C connection D friendship
解析：该题正确答案为A. keep in touch为短语动词，意为"保持联系"。
例3 ____! There's a train coming.
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。
式｜语态 主动语态 被动语态
一般式 to write to be written
完成式 to have written to have been written
进行式 to be writing ?
完成进行式 to have been writing ?
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 ordered her to leave at once.
He was forced to obey his order.
（6） 作状语
He got up early to catch the first bus.
He worked hard to catch up with the other students.
（7） 作独立成分
To tell you the truth, I told a lie.
（8） "疑问词＋不定式"结构。 如：
I don't know how to choose them.
I cannot decide where to go.
（9）不定式的否定式。如：
I decided not to go.
（10）不定式的完成式。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。
式 | 语态 主动语态 被动语态
一般式 writing being written
完成式 having written having been written
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。
