2. 反身代词

第一人称第二人称第三人称

单数复数单数复数单数复数

myself ourselves yourself yourselves himself/herself/itself themselves

(1)作动词或介词的宾语:经常在enjoy, teach, hurt, buy, introduce, seat, dress, express, amuse, behave等动词和by, for, to, of等介词后作宾语。通常表示反身代词与句中的主语是同一人。它在句中作宾语,不能省略,否则该句是一个意义不完整的错句。如:

He is teaching herself English.她在自学英语。

She was talking to herself.她自言自语。

He lives by himself in the country.他独自住在乡下。

(2)作主语或宾语的同位语:主要起加强语气的作用,译作“亲自,本身,本人”。如:Did you make the cake yourself?这蛋糕是你亲自做的吗?(yourself作主语you的同位语)

The work itself is easy.这工作本身很容易。(itself作主语the work的同位语)

Did you see Mr. Wang himself?你见过王先生本人吗?(himself作宾语Mr. Wang的同位语)

(3)作表语:在be, feel, look, seem等系动词后作表语,表示身体或精神状态处于正常。如:I’m not myself today.今天我感觉不舒服。

I am feeling myself again.我觉得健康如昔。

3 祈使句讲解

一、祈使句:用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句. 祈使句的作用是要求、请求或命令、劝告、建议别人做或不做一件事。祈使句的句末一般用感叹号,但是有些祈使句的语气较弱,可以用句号结尾

祈使句因对象(即主语)是第二人称,所以通常都省略。祈使句的动词都为一般现在时,例:Go and wash your hands. 例如:保持肃静!Be kind to our sister. Watch your steps. 表示禁止的句式有:不准、不要、别、No parking.

二、表现形式

●肯定结构:

1. Do型(即:动词原形(+宾语)+其它成分)。如:Please have a seat here.

有的祈使句在意思明确的情况下,动词可省略。如:This way, please. = Go this way, please. 。

2. Be型(即:Be + 表语(名词或形容词)+其它成分)。如:Be a good boy! 要做一个好孩子!

3. Let型(即:Let + 宾语+ 动词原形+ 其它成分)。如:Let me help you. 让我来帮你。

●否定结构:

1. Do型和Be型的否定式都是在句首加don\'t构成,如:Don\'t forget me! Don\'t be late for school!

2. Let型的否定式有两种:“Don\'t + let + 宾语+ 动词原形+ 其它成分”和“Let + 宾语+ not + 动词原形+ 其它成分”。如:Don\'t let him go. / Let him not go. 别让他走。

3. 有些可用no开头,用来表示禁止性的祈使句。如:No smoking! No fishing! 禁止钓鱼!

用"let"的祈使句时,必须注意下列几点:

1、"let" 的否定句有二。如果宾语是第三人称用"Don't let.....";如果宾语是第一人称,则用"Let......not" :

Don't let this type of things happen again.

It's raining now. Let's not go out until after the rain.

2、"Let"只适用于现在时态,可以有被动语态(the passive voice),如:

Let the recalcitrant criminals be sent to prison.

Let all the dedicated capable staff be promoted.

3、"Let"后头除了是不带"to"的不定式动词(The infinitive without "to")之外,还可以是某些适当的副词,如out, in, down, alone等:

Let the puppy out.

Open the windows and let the fresh air in.

The room is too sunny. Let the blinds down.

Let me alone, please.

用"Let\'s"时,把谈话者的对象包括在内;用"Let us"时,并不包括对方,如:

Let's try it, shall we?

Let us do it by ourselves, will you?

三.祈使句与并列连词and与or 连用时可以表示条件。

Work harder, and you will catch up with your classmates.

4 情态动词should ,ought to, had better 的用法

一.Should 和ought to

1表达职责或义务,提出劝告及一般人们认为应该去做的事,常用来谈论现在和将来。

Ought you to eat so much ?

2.should用于否定句,多表示做了不应该做的事。Ought to 的否定形式是ought not to ,口语中常用oughtn’t to

You oughtn’t to eat so much .

3.在大多数情况下should 和ought to 的意思大致相同。Should比ought to 语气要轻一些。另外,当我们用should时,谈的是自己的主观看法;ought to 则更多反应客观情况。如:

You should/ought to go and see Mr Wang sometime.

二.had better

1.had better do… “最好” had常缩写为’d 否定式had better not do

一般疑问句把had 放在主语的前面。

1) You’d better hurry up if you want to get home before dark.

2)We’d better not disturb him.

3) Had we better go now? 我们最好现在走吗?

2.had better 适用于任何人称和数

You’d better go with me.

3.变为一般疑问句时,如果是肯定句,就把had提前,放在句首;如果是否定句,就把hadn’t 提前即可。Had you better go there at once?

4.含有had better的反义疑问句的简短问句部分中要用had或hadn’t.如:

You had better give him the magazine, hadn’t you ?

may 的用法

一、表示许可或征求对方的许可,有“可以”的意思。例如:

You may go now. 你可以走了。

May I use your computer? 我用一下你的电脑可以吗?

二、回答以 may 开头的疑问句有如下表达法:

-May I smoke here? 我可以在这儿抽烟吗?

-Yes, you may. / Yes, please. 请抽吧。

-No, you can't. / No, you mustn't. / No, you'd better not. 请不要抽烟。

三、表示猜测,通常只用于陈述句。例如:

You may be right. 你可能是对的。

四、在口语中can 可以代替may 表示许可,但can 较随便,may 更正式。例:

Can I use your bike, John? 约翰,我可以用一下你的自行车吗?

May I have a look at your license please, sir? 先生,我可以看一下你的执照吗?

can 的用法

一、表能力,有“能,会,能够”的意思。例如:

-Can you drive a car? 你会开车吗?

-Yes, I can. 我会。/ No, I can't. 我不会。

二、表允许,在口语中代替may,有“可以”的意思。

(见下面 may 的用法第四点)

三、表示可能性,常用于否定句和疑问句。例如:

Can it be true? 那会是真的吗?

Today is Sunday. He can't be at school. 今天是星期天,他不可能在学校里。

5 动词不定式

(1) 概念

动词不定式是由“to+动词原形”构成。动词不定式是一种非限定性动词,在句中不能单独充当谓语。(非限定性动词可分为不定式,动名词,现在分词和过去分词,他们在句中不能单独充当谓语。)动词不定式相当于名词、形容词或副词,在句中可以作句子除谓语之外的任何句子成分。

(2) 句型

①主语+ vt. (及物动词) + to-v (动词不定式)

want, decide, wish, hope, choose, refuse, would like, expect, …

He decided to go there himself. 他决定亲自去那儿。

②主语+ vt. (及物动词) + to-v (动词不定式)

stop, go on, remember, forget, start, begin, …

Please remember to bring the book to school next time.请记住下次把书带到学校来。

③主语+ vt.(及物动词) +it + adj.(形容词) + to-v (动词不定式)

find, think, make, feel, …

The Internet makes it easy to get much new information in a short time.

④ 主语+ vt.(及物动词) +sb./sth.+ (not) + to-v (动词不定式)

get, allow, encourage, beg, wait for, warn, ask, want, would like, tell, wish, expect, invite, …

It’s raining hard now. Let’s wait for the rain to stop. 雨下得很大,让我们等雨停下来。 ⑤ 主语+ vt.(及物动词) +sb./sth.+ (not) + v (动词原形)

feel, listen to, hear, let, make, have, see, watch, look at, notice, …

The workers was made to work twelve hours a day. 工人们被迫每天工作十二小时。 ⑥ 主语+ vt.(及物动词) +sb./sth.+ 疑问词 + to-v (动词不定式)

teach, show, know, …

I don’t know whether to go th ere. 我不知道是否去那儿。

6 英语的简单句有五种基本句型: 主+谓(S+V ); 主+谓+宾(S+V+O); 主+系+表(S+V+P);

主+谓+间宾+直宾(S+V+IO+DO); 主+谓+直宾+宾补(S+V+DO+OC)。 掌握这五种基本句型,是掌握各种英语句子结构的基础。

7 过去进行时

1) 掌握过去进行时was / were + doing 表示过去某个时刻正在进行的动作,其肯定、否定和疑问形式如下:

was/were(+not) ing form I

was(+not)

dancing.

You/We/They were(+not) He/She/It was(+not)

Was I

dancing?

Were you/we/they Was he/she/it

Yes, I

was. you/we/they were. he/she/it

was.

No,

I

was not/wasn’t. you/we/they were not/weren’t. he/she/it

was not/wasn’t.

while, when, as

掌握while 和 when 在过去进行时中的用法:表示两个持续性的动作在过去同时发生用while ,when 后接

一个短暂性的动作。持续性的动作用过去进行时,短暂性的动作用一般过去时。e.g.:

I was doing my homework while my father was watching TV..

The bell rang while he was reading books.

When the bell rang, he was reading books. (以上这两句主从句前后可以互换)

1、“主短从长”型:即主句是一个短暂性动作,而从句是一个持续性动作,此时三者都可用。如:

Jim hurt his arm while[when, as] he was playing tennis. 吉姆打网球时把手臂扭伤了。

As[When, While] she was waiting for the train, she became very impatient. 她在等火车时,变得很不耐烦。

2、“主长从长”型:即主句和从句为两个同时进行的动作或存在的状态,且强调主句动作或状态延续到从句所指的整个时间,此时通常要用while。

I always listen to the radio while I’m driving. 我总是一边开车一边听收音机。

He didn’t ask me in; he kept me standing at the door while he read the message.

他没有让我进去,他只顾看那张条子,让我站在门口等着。

但是,若主句和从句所表示的两个同时进行的动作含有“一边……一边”之意时,则习惯上要用as。如:He swung his arms as he walked. 他走路时摆动着手臂。

3、“主长从短”型:即主句是一个持续性动作,而从句是一个短暂性动作,此时可以用as或when,但不能用while。如:

It was raining hard when [as] we arrived. 我们到达时正下着大雨。

When [As] he came in, I was listening to the radio. 他进来时,我在听收音机

(UNIT1)现在完成时的重点和难点 一、现在完成时的完成用法和未完成用法 1.现在完成时的完成用法 现在完成时的完成用法指的是动作发生在过去某一时刻并已结束,但该动作对现在产生了影响,与现在情况具有因果关系。例如:He has turned off the light.他已把灯关了。 (动作结束于过去,但说明的是现在的情况--灯现在不亮了。) 现在完成时完成用法的特点是动作不延续,因此,该时态只能与表示不定的过去时间状语(如:already,yet,before,recently等)、频度时间状语(如:never,ever,once等)、 包括现在时刻在内的时间状语(如:this morning / month /year...,today等)连用。 例如: Have you found your pen yet?你已找到你的钢笔了吗? 2.现在完成时的未完成用法 现在完成时的未完成用法指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续 下去。 例如:He has lived here since 1978.自从1978年以来,他一直住在这儿。(动作起始 于1978年,一直住到现在,可能还要继续住下去。) I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前,一直延续至今,有可能还要继续下去。) 此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相 连的时间状语(如:up to now,so far到目前为止)等。 例如:I have heard nothing from him up to now.到目前为止我没有他的任何消息。 注意:(1)现在完成时的未完成用法只适用于延续性动词,不可用于终止性动词,即瞬间完成 或延续时间很短的动词。如:come,go,arrive,leave,join,become,die等。 (2)现在完成时常见两种句型: ①主语+have / has been+for短语 ②It is+一段时间+ since从句 例如:He has been in the League for three years.或It is three years since he joined the League. 他入团已三年了。 3、延续性动词和终止性动词的概念 英语中,动词按其动作发生的方式、动作发生过程的长短,可分为延续性动词和终止性动词。 延续性动词表示能够延续的动作,这种动作可以延续下去或产生持久影响。如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。 终止性动词也称非延续性动词、瞬间动词或短暂性动词,表示不能延续的动作,这种动作发生后 立即结束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow,buy等。 4、延续性动词的用法特征 1.延续性动词可以用于现在完成时,其完成时态可与表示段时间的状语连用。表示段时间的 短语有:for two years, during the past three years, since last year, how long等。如:I have learned English since I came here.自从我来到这儿就学英 语了。

7B unit1 1. 基数词:表示数目的数词为基数词,它在句中主要作定语,也可作主语、宾语、表语和同位语等。关于基数词的用法我们要注意以下几点: (1)基数词的构成: ①21至99的两位数:十位数与个位数之间加连字符。如:22 = twenty-two 78 = seventy-eight ②三位数:百位数与最后两位数之间(若十位数为0,则与个位数之间),要加and(美 国英语中可省去and)。如: 101 = one hundred(and)one 999 = nine hundred(and)nine ③四位数:thousand之后,百位数之前加逗号,百位数与十位数之间(若十位数为0,则与个位数之间)加and。如: 1,401 = one thousand,four hundred and one ④表示一万以上的大数目:将数字从个位起每向前三位加一逗号,使一个数分成若干小节,分别称为thousand节,million节等,然后按节处理。如: 101,203,001 = one hundred and one million,two hundred and three thousand and one. ⑤表示十亿,美国用one billion,英国用one thousand million. (2)基数词的运用: 以上这些表示确切数目的数词中,hundred,thousand,million,billion等一般用单数形式。但在以下几种情况里,基数词以复数形式出现。 ①用于表示不定数目。如: hundreds of (数百的) thousands of (数千的) millions of (数百万的) ②表示“几十”的数词,其复数形式可以表示年龄或年代。如: He doesn't look like an old man in his eighties. 他看上去不像80来岁的老人。 ③其他习惯用法。如:in two sand threes 三三两两的 2. 序数词:表示顺序的数词为序数词,它在句中主要作定语,也可作主语、宾语、表语和同位语等。关于序数词的用法我们要注意以下几点: (1)序数词的构成: ①除first,second,third外,从第四开始,由相应的基数词加词尾-th构成序数词。 ②以ty结尾的基数词先将y变成ie,再加词尾—th构成序数词。 Twenty---twentieth forty---fortieth ③有少数几个基数词构成序数词时,拼写有变化。如: five-fifth eight-eighth nine-ninth twelve-twelfth ④第二十一至第九十九:十位数用基数词,个位数用序数词。如: 第二十一 twenty-first,缩写为21st 第九十三 ninety-third,缩写为93rd ⑤百位数的序数词:百位数用基数词+百位以后最末两位(或)一位的序数词。如: 第一百零一 one hundred and first,缩写为101st 第一百二十三 one hundred and twenty-third,缩写为123rd 7bunit 2 一般将来时 表示将来某个时间要发生的动作或存在的状态,也表示将来经常或反复发生的动作。常常与表示将来的时间状语连用。常用的表达形式共有五种,现归纳如下: 结构:shall/will/be going to +do 只有第一人称I,we用shall. 用will或shall表示
