定冠词的定义:
定冠词the 有this,that,these,those等意义,但较弱,用于单数或复数名词前,主要用来特指,使一个或几个事物区别于所有其他同名的事物。
定冠词通常位于名词或名词修饰语前,但放在both、all、double、half、twice等词之后。
如:All the students in the class went out.班里所有的学生都出去了。

He bought a piano for his son. 他为儿子买了部钢琴。
定冠词与不定冠词互换用法比较:
1、在形容词最高级前一般加定冠词。但有时却用不定冠词,这时它不表示“最”的意思,而表示“非常”“很”的意思。
如:This is the most important question of all. 这是所有问题中最重要的一个。
This is a most important question. 这时一个非常重要的问题。
2、在序数词前加定冠词,表示“第几”;加不定冠词则表示“又”“再”。

3、在有些短语中,用定冠词和不定冠词一样。

物主代词的概念:
表示所有关系的代词叫物主代词。
物主代词有两种形式:一种是形容词性物主代词,在句中只能充当定语;另一种是名词性物主代词,和名词用法相同,在句中作主语、宾语、表语等。
物主代词的特性:
1、物主代词既有表示所属的作用又有指代作用。
例如:John had cut his finger;约翰割破了手指。
物主代词有形容词性(my,your等)和名词性(mine,yours等)两种,形容词性的物主代词属于限定词。
名词性的物主代词在用法上相当于省略了中心名词的“'s”属格结构,
如:Jack's cap 意为 The cap is Jack's.
His cap 意为 The cap is his.
2、名词性物主代词的句法功能:
a.作主语,例如:May I use your pen? Yours works better.
b.作宾语,例如:I love my motherland as much as you love yours.
c.作介词宾语,例如:Your should interpret what I said in my sense of the word,not in yours.
d.作主语补语,例如:The life I have is yours. It's yours. It's yours. 我的生命属于你,属于你,属于你。

如:We should treat her mother very well.
2、与own连用表示强调。
如:I saw it with my own eyes.
名词性物主代词的用法:
1、名词性物主代词可作主语、表语和宾语。
如:This is my desk. Yours is over there.
2、名词性物主代词常用于双重属格,于of连用。
如:This girl is a friend of mine.
物主代词知识体系:
物主代词特别用法:
1、名词性和形容词性物主代词不能混用。
如:Jack has a low opinion of Sue.
2、物主代词的单复数必须和它所指代的名词一致。
如:His idea is to do more practice every day.
3、对于anyone,anybody,everyone,everybody,应根据上下文来判断his或her,有时也可用their。
如:Has everyone finished their work?
关系代词的概念:
英语中的关系代词有who, whom, whose, that, which, 它们是用来引导定语从句的。关系代词既代表定语从句所修饰的词,又在其所引导的从句中承担一个成分,如主语、宾语、表语、或定语。
如:This is the man who saved your son. (who在从句中作主语,先行词是man)
The man whom I met yesterday is Jim.
A child whose parents are dead is an orphan.
He wants a room whose window looks out over the sea.
关系代词用法:
1、that与which的用法区别:
两者都可指物,常可互换。其区别主要在于:
(1)引导非限制性定语从句时,通常要用which:
如:She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请,这是她意想不到的。
(2)直接放在介词后作宾语时,通常要用which:
如:The tool with which he is working is called a hammer. 他干活用的那个工具叫做锤子。
(3)当先行词是下列不定代词或被它们修饰时much, little, none, all, few, every(thing), any(thing), no(thing)等时,通常用that:
如:There was little that the enemy could do but surrender. 敌人无法,只有投降了。
All[Everything] that can be done must be done. 凡能做的事都必须做。
(4)当先行词有the very, the only, the same等修饰时,通常用that:
如:This is the only example that I know. 我知道的例子只有这一个。
Those are the very words that he used. 那是他的原话。
(5)当先行词有形容词最高级或序数词(包括last, next等)等修饰时,通常用that:
如:This is the best dictionary that I've ever used. 这是我用过的最好的词典。
The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。
(6)当关系代词在定语从句中用作表语时,通常用that:
如:China is not the country(that) it was. 中国已不是过去的中国了。
(7)当先行词是一个既指人又指物的并列词组时,通常用that:
如:They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。
(8)当要避免重复时:
如:Which is the course that we are to take? 我们选哪门课程?
2、that与who的用法区别:
(1)两者均可指人,有时可互换:
如:All that[who] heard him were delighted. 所有听了他讲话的人都很高兴。
Have you met anybody that[who] has been to Paris? 你遇见过到过巴黎的人吗?
He is the only one among us that[who] knows Russian. 他是我们中间唯一懂俄语的人。
(2)但是在下列情况,通常要用that:
①当先行词是一个既指人又指物的并列词组时:
如:I made a speech on the men and things that I had seen abroad. 我就我在国外所见到的人和事作了报告。
②当先行词是who时(为避免重复):
如:Who was it that won the World Cup in1982? 谁赢得了1982年的世界杯?
③当关系代词在定语从句中作表语时(可省略):
如:Tom is not the boy(that) he was. 汤姆这孩子已不是以前那个样子了。
关系代词知识体系:
关系代词用法拓展:
1、as与which的用法区别:
(1)引导限制性定语从句时,在such,as,thesame后只能用as,其他情况用which:
如:I never heard such stories as he tells. 我从未听过他讲那样的故事。
It's the same story as I heard yesterday. 这故事跟我昨天听到的一样。
This is the photo which shows my house. 这张照片拍的是我的住宅。
(2)引导非限制性定语从句时,有时两者可互换:
如:I live a long way from work, as [which] you know. 我住得离工作单位很远,这你是知道的。
(3)但在,在以下情况引导非限制性定语从句时,两者不可换用:
①当从句位于主句前面时,只用as:
如:As is known to everybody, the moon travels round the earth once every month. 月球每月绕地球转一周,这是每个人都清楚的。
②as引导的非限制性定语从句应与主句在意义上和谐一致,which无此限制:
如:He went abroad, as[which] was expected. 他出国了,这是大家预料到的。
He went abroad, which was unexpected. 他出国了,这让大家感到很意外。(不用as)
③as引导非限制性定语从句时,先行词通常不能是主句中某个具体的词,而应是整个句子、整个短语或某个短语推断出来的概念,而which则无此限制:
如:The river, which flows through London, is called the Thames. 这条流经伦敦的河叫泰晤士河。(不用as)
④当as引导非限制性定语从句作主语时,其谓语通常应是连系动词,而不宜是其他动词,而which则无此限制:
如:She has married again, as[which] seemed natural. 她又结婚了,这似乎很自常。
She has married again, which delighted us.她又结婚了,这使我们很高兴。(不用as)
2、who与whom的用法区别:
两者均只用于人,从理论上说,who为主格,whom为宾格:
如:Where's the girl who sells the tickets? 卖票的女孩在哪里?
The author whom you criticized in your view has written a letter in reply. 你在评论中批评的那个作者已写了一封回信。
但实际上,除非在正式文体中,宾格关系代词whom往往省略不用,或用who或that代之:
如:The man(that, who, whom) you met just now is called Jim. 你刚遇见的那个人叫吉姆。
不过,在以下几种情况值得注意:
(1)直接跟在介词后面作宾语时,只能用whom,而且不能省略:
如:She brought with her three friends, none of whom I had ever met before. 她带了3个朋友来,我以前都没见过。
(2)引导非限制性定语从句且作宾语时,who和whom均可用,但以用whom为佳,此时也不能省略:
如:This is Jack, who[whom] you haven't met before. 这是杰克,你以前没见过。
形容词的概念:
形容词(adjective),简称adj.或a,形容词用来修饰名词或代词,表示人或事物的性质、状态,和特征的程度好坏与否,形容词在句中作定语、表语、宾语补足语。通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面。
形容词的作用与位置:
形容词是用来修饰名词的,常被放在名词前作定语,或放在系动词后面作表语。以下属几种特殊情况,须牢记;
(1)形容词短语作定语,定语后置。
如:a language difficult to master,
a leaning tower about 180 feet high
(2)表语形容词(afraid、alike、alone、asleep、awake、alive等)作定语,定语后置。如a man alive。有些表身体健康状况的形容词如well、faint、ill只作表语。sick既可作表语又可作定语,ill如作定语意为“bad”。
(3)用作定语,修饰由不定代词one、no、any、some和every构成的复合词如anything、something等时,通常后置。
如:I have something important to tell you.
(4)else常用作疑问代词和不定代词的后置定语。
(5)enough、nearby修饰名词前置或后置,程度副词一般位于形容词、副词前面,enough修饰形容词、副词时,必须后置。
(6)几个并列的形容词作定语,其语序通常为:限定语(The、A)+描绘性形容词+size(大小)+shape(形状)+age(年龄、时间)+color(颜色)+origin(国籍、来源)+material(材料)+purpose(目的)+名词。
口诀:
限定描绘大长高,形状年龄和新老;颜色国籍跟材料,作用类别往后靠。
如:a heavy black Chinese steel umbrella,
the man's first tow interesting little red French oil paintings
形容词的用法:
1、形容词修饰名词,说明事物或人的性质或特征。通常,可将形容词分成性质形容词和叙述形容词两类,其位置不一定都放在名词前面:
1)直接说明事物的性质或特征的形容词是性质形容词,它有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语。例如:hot热的。
2)叙述形容词只能作表语,所以又称为表语形容词。这类形容词没有级的变化,也不可用程度副词修饰。
大多数以a开头的形容词都属于这一类。例如:
afraid害怕的。(错)Heisanillman. (对)Themanisill. (错)Sheisanafraidgirl. (对)Thegirlisafraid.
这类词还有:well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake等。
3)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后。例如:somethingnice
2、用形容词表示类别和整体:
1)某些形容词加上定冠词可以泛指一类人,与谓语动词的复数连接。如:the dead,the living,the rich,the poor,the blind,the hungry The poorarelosinghope.穷人失去了希望。
2)有关国家和民族的形容词加上定冠词指这个民族的整体,与动词的复数连用。如:the British,the English,the French,the Chinese. The English have wonderful senseofhumor.
以-ly结尾的形容词:
1)大部分形容词加-ly可构成副词。但friendly,deadly,lovely,lonely,likely,lively,ugly,brotherly,仍为形容词。改错:
如:(错)She sang lovely.
(错)He spoke to me very friendly.
(对)Her singing was lovely.
(对)He spoke to me in a very friendly way.
2)有些以-ly结尾既为形容词,也为副词。 daily,weekly,monthly,yearly,early .
如:The Times is a daily paper.
The Times is published daily.

副词的位置:
1)在动词之前。
2)在be动词、助动词之后。
3)多个助动词时,副词一般放在第一个助动词后。
注意:
a. 大多数方式副词位于句尾,但宾语过长,副词可以提前,以使句子平衡。
如:We could see very clearly a strange light ahead of us.
b. 方式副词well,badly糟、坏,hard等只放在句尾。
如:He speaks English well.
副词的排列顺序:
1)时间,地点副词,小单位的在前,大单位在后。

副词知识体系:
动词的定义:
表示动作中状态的词叫做动词。根据其在句中的功能,动词可分为行为动词、系动词、助动词和情态动词四类,有些动词是兼类词。
例如:We have lunch at 12. (have是行为动词)
We have been to NewYork. (have是助动词)
I am hungry. (am是系动词)
You need not have waited for me. (need是情态动词)
The door needs painting. (need是兼类词)
动词的分类:
1)表示动作中状态的词叫做动词。
2)根据其在句中的功能,动词可分为四类,分别是:
实义动词(Notional Verb)、系动词(Link Verb)、助动词(Auxiliary Verb)、情态动词(Modal Verb)。
说明:有些情况下,有些动词是兼类词。
例如:We are having a meeting. 我们正在开会。(having是实义动词。)
He has gone to NewYork.他已去纽约。(has是助动词。)
3)动词根据其后是否带有宾语,可分为两类,分别是:
及物动词(Transitive Verb)、不及物动词(Intransitive Verb),缩写形式分别为vt.和vi.。
说明:同一动词有时可用作及物动词,有时可用作不及物动词。
例如:She can dance and sing. 她能唱歌又能跳舞。(sing在此用作不及物动词。)
She can sing many English songs. 她能唱好多首英文歌曲。(sing用作及物动词。)
4)根据是否受主语的人称和数的限制,可分两类,分别是:
限定动词(Finite Verb)、非限定动词(Non-finite Verb)。
例如:She sings very well. 她唱得很好。(sing受主语she的限制,故用第三人称单数形式sings。)
She wants to learn English well. 她想学好英语。(to learn不受主语she的限制,没有词形变化,是非限定动词。
说明:英语中共有三种非限定动词,分别是:动词不定式(Infinitive)、动名词(Gerund)、分词(Participle)。
5)根据动词的组成形式,可分为三类,分别是:
单字词(One-Word Verb)、短语动词(Phrasal Verb)、动词短语(Verbal Phrase)
例如:The English language contains many phrasal verbs and verbal phrases. 英语里有许多短语动词和动词短语。(contains是单字动词。)
Students should learn to look up new words in dictionaries. 学生们学会查字典。(look up是短语动词。)
The young ought to take care of the old. 年轻人应照料老人。(takecareof是动词短语。)
6)动词有五种形态,分别是:
原形(OriginalForm)、第三人称单数形式(Singular From in Third Personal)、过去式(Past Form)、过去分词(Past Participle)、现在分词(Present Participle)。
动词知识体系:
动名词概念:
动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语,也能被副词修饰,动名词有时态和语态的变化。
现在分词和动名词用法比较:
动词的-ing形式包括现在分词和动名词两种形式。他们的句法功能如下:
动词的-ing形式如果作句子的主语或者宾语时,应该是动名词形式;如果作补语或者状语时,应该是现在分词形式。那么作表语或者定语的动名词和现在分词又该怎样区分呢?
1、动名词与现在分词作表语时的比较:
(1)动名词作表语说明主语的内容,回答what的问题;现在分词作表语相当于形容词作表语,说明主语的性质、特征等,回答how的问题。
如:One of the best exercises is swimming. 游泳是最好的运动项目之一。
What pleases him most is bathing in the sea. 最使他高兴的事是在海中沐浴。
The situation both at home and abroad is very in-spiring. 国内外的形势都很鼓舞人心。
The color is pleasing to the eye. 颜色悦目。
(2)动名词作表语,表语和主语几乎处于同等地位,可以互换位置,其句意不变;现在分词作表语,表语和主语则不能互换位置。
如:Our work is serving the people.
(=Serving the people is our work.)我们的工作是为人民服务。
The news was disappointing. 那消息令人失望。
(3)作表语的现在分词前可以用very,quite,rather,greatly等副词修饰,而动名词则不可以。
如:What he said was very encouraging. 他的话很鼓舞人心。
Our goal is realizing the four modernizations in the near future. 我们的目标是在不久的将来实现四个现代化。
(4)现在分词与形容词一样可以和more,the most构成形容词的比较级和最高级,而动名词则不可以。
如:The story is the most fascinating. 那个故事最迷人。
(5)作表语用的现在分词除了和be连用以外,还可以和其它的系动词连用;而作表语的动名词则通常只能和be连用。
如:His speech seems inspiring.他的演讲似乎很鼓舞人心。
His interest is writing for the news papers. 他的爱好是给报社写文章。
(6)有些用作表语的现在分词已经形容词化了。常见的有:exciting,moving,inspiring,missing,interesting,disappointing等。
2、动名词与现在分词作定语时的比较:
(1)动名词作定语时,表示它所修饰的名词的性能和用途,和它所修饰的名词在逻辑上没有主谓关系;
现在分词作定语时,表示它所修饰的名词正在进行的动作,和它所修饰的名词在逻辑上有主谓关系,常可以扩展成一个定语从句。
如:a swimming girl=a girl who is swimming 一个在游泳的姑娘
a walking stick=a stick that is used for walking 一根拐杖
(2)现在分词作定语有时可以后置,而动名词则通常只能放在它所修饰的名词之前。
如:The girl wearing glasses is one of his students. 戴眼镜的那个女孩是他的一个学生。
I bought some reading materials. 我买了一些阅读材料。
动名词的用法:
1、作主语:
例如:Fighting broke out between the South and the North. 南方与北方开战了。
2、作宾语:
a. 有些动词可以用动名词作宾语。
例如:admit承认 appreciate感激 avoid避免 complete完成 consider认为 delay耽误 deny否认 detest讨厌 endure忍受 enjoy喜欢 escape逃脱 fancy想象 finish完成 imagine想象 mind介意 miss想念 postpone推迟 practice训练 recall回忆 resent讨厌 resume继续 resist抵抗 risk冒险 suggest建议 face面对 include包括 stand忍受 understand理解 forgive宽恕 keep继续
例如:Would you mind turning down your radio a little, please? 你把收音机音量调小一点,好吗?
The squirrel was lucky that it just missed being caught. 这松鼠幸运得很,刚逃避了被逮住的厄运。
b. 有些结构后面可以用动名词作宾语或其他成分。
例如:admit to prefer...to burst out keep on insist on count on set about put off be good at take up give up be successful in be used to lead to devote oneself to object to stick to no good no use be fond of look forward to be proud of be busy can't help be tired of be capable of be afraid of think of
3、作表语,对主语说明、解释:
例如:Her job is washing, cleaning and taking care of the children. 她的工作是洗刷、清扫和照顾孩子。
比较:She is washing, cleaning and taking care of the children.
4、作定语,一般表示所修饰名词事物的用途:
例如:a writing desk=a desk for writing 写字台
a swimming pool=a pool swimming 游泳池
有些动名词作定语,与所修饰的名词关系比较复杂。
例如:boiling point=a temperature point at which something begins to boil 沸点
a walking tractor=a tractor which a driver can operate while he or she is walking behind it 手扶拖拉机
动名词知识体系:
动名词与不定式用法对比:
动词不定式的概念:
动词不定式指由to加上动词原形(而且只能是动词原形)所构成的一种非限定性动词,但在有些情况下to可以省略。动词不定式在语法功能上可作主语、宾语、宾语补足语、
表语、定语和状语。
不定式的特殊句型对比:
1、不定式的特殊句型too…to…:
1)too…to 太…以至于…。
例如:He is too excited to speak. 他太激动了,说不出话来。
—Can I help you? 需要我帮忙吗?
—Well, I'm afraid the box is too heavy for you to carryi t, but thank you all the same. 不用了。这箱子太重,恐怕你搬不动。谢谢。
2)如在too前有否定词,则整个句子用否定词表达肯定,too后那个词表达一种委婉含义,意为“不太”。
例如:It's never too late to mend. 改过不嫌晚。(谚语)
3)当too前面有only, all, but时,意思是:非常…等于very。
例如:I'm only too pleased to be able to help you. 能帮助你我非常高兴。
He was but too eager to get home. 他非常想回家。
2、不定式的特殊句型so as to:
1)表示目的:它的否定式是so as not to do。
例如:Tom kept quiet about the accident so as not to lose his job. 汤姆对事故保持沉默是为了不丢掉他的工作。
Go in quietly so as not to wake the baby. 轻点进去,别惊醒了婴儿。
2)表示结果:
例如:Would you be so kind as to tell me the time? 劳驾,现在几点了。
3、不定式的特殊句型:Why not:
“Whynot+动词原形”表达向某人提出建议,翻译为:为什么不……? 干吗不……?
例如:Why not take a holiday?
不定式的用法:
1、不定式作补语:
1)有些有动词+宾语+不定式的结构。
例如:advise allow cause challenge command compel drive驱使
enable encourage forbid force impel induce instruct invite like/love order permit make let have want get warn persuade request send tell train urge 等。
例如:Father will not allow us to play on the street. 父亲不让我们在街上玩耍。
The officer ordered his men to fire. 长官命令士兵开火。
注意:有些动词如make,have,get,want等可用不定式作做宾补,也可用分词作宾补。现在分词表达主动,也表达正在进行,过去分词表达被动。
2)有些有动词+宾语+不定式的结构,不定式的动词往往是be,不定式一般可以省去。
例如:consider find believe think declare(声称) appoint guess fancy(设想) guess judge imagine know 等。
例如:We believe him to be guilty. 我们相信他是有罪的。
We know him to be a fool. 我们知道他是个笨蛋。(tobe不能省去)
典型例题:Charles Babbage is generally considered___the first computer.
A. to invent
B. inventing
C. to have invented
D. having invented
答案:C. 一般没有consider+宾语+be以外不定式的结构,也没有consider+宾语+doing的结构,排除A、B、D。consider用动词be以外的不定式作宾补时,一般要求用不定式的完成式,故选C。 3)有些动词可以跟there+to be的结构。例如:believe expect intend like love mean prefer want wish understand 等。
例如:We didn't expect there to be so many people there. 我们没料到会有那么多人在那里。
You wouldn't want there to be another war. 你不至于想让另外一场战争发生吧。
2、不定式作主语:
不定式作主语,往往用it作形式主语,真正的主语不定式放至句子的后面。
例如:It's so nice to hear your voice. 听到你的声音真高兴。
It's necessary for you to lock the car when you do not use it. 不用车的时候,锁车是有必要的。
It's very kind of you to help us. 他帮助我们,他真好。
It seemed selfish of him not to give them anything. 他不给他们任何东西,这显得太自私了。
3、不定式作表语:
不定式可放在be动词后面,形成表语。
例如:My work is to clean the room every day. 我的工作是每天清扫房间。
His dream is to be a doctor. 他的梦想是成为一名医生。
4、不定式作定语:
不定式做定语通常要放在被修饰的词后,往往表示未发生的动作。
例如:I have a lot of work to do.我有许多事要做。
There was nothing to bring home that morning. 那天早上(他回家时)两手空空。
5、不定式作状语:
1)目的状语:常用结构为to do,only to do(仅仅为了), in order to do,so as to do,so(such)...asto…(如此…以便…)。
例如:He ran so fast as to catch the first bus. 他飞快地跑以便赶上第一班车。
I come here only to say good-bye to you. 我来仅仅是向你告别。
2)作结果状语,可以表示没有预料到的或事与愿违的结果,不定式要放在句子后面。
例如:I awoke to find my truck gone. 我醒来发现箱子不见了。
He searched the room only to find nothing. 他搜索了房间,没发现什么。
3)表原因:
例如:I'm glad to see you. 见到你很高兴。
She wept to see the sight. 她一看到这情形就哭了。
4)表示理由和条件:
例如:He must be a fool to say so.
You will do well to speak more carefully.
You will do well to speak more carefully.
不定式知识体系:
不定式用法拓展:
1、用作介词的to:
to可以用作介词,也可用作不定式的标示。下面的to都用作介词:admit to object to beaccus to med to beused to stick to turn to开始 look forward to be devoted to pay attention to contribute to apologize to devote oneself to
2、省去to的动词不定式:
1)情态动词(除ought外)后。
2)使役动词let,have,make后,感官动词see, watch, lookat, notice, observe, hear, listento, smell, feel, find等后。
注意:被动语态中不能省去to。
例如:I saw him dance. 我看见他跳舞。=He was seen to dance.
The boss made them work the whole night. 老板让他们整夜干活。 =They were made to work the whole night.
3)would rather,had better句型后:
4)Why…/why not…句型后:
5)help后可带to,也可不带to, help sb(to)do sth:
6)but和except后:
but前是实义动词do时,后面出现的不定式不带to。
比较:He wants to do nothing but go out. 他只想出去玩。
He wants to believe anything but to take the medicine. 除了吃这药,他什么都信。
7)由and, or和than连接的两个不定式,第二个to可以省去:
8)通常在discover, imagine, suppose, think等词后作宾补时,可以省去to be。
例如:He is supposed(to be)nice. 他应该是个好人。
3、动词不定式的否定式在不定式标志to前加上not。
例如:Tell him not to shut the window。让他别关窗。
She pretended not to see me when I passed by. 我走过的时候,她假装没看见。
4、It's for sb. 和It's of sb. 这样的句子中,由于表语形容词性质的不同,导致了不定式逻辑主语标志用for或of的区别。
1)for sb. 句型中的形容词一般为表示事物的特征特点,表示客观形式的形容词,如easy, hard, difficult, interesting, impossible等:
例如:It's very hard for him to study two languages. 对他来说学两门外语是很难的。
2)of sb句型中的形容词一般为表示性格,品德,心智能力,表示主观感情或态度的形容词,如good, kind, nice, clever, foolish, right。
例如:It's very nice of you to help me. 你来帮助我,你真是太好了。用for还是用of的另一种辨别方法:用介词for或of后面的逻辑主语作句子的主语,用介词前边的形容词作表语,造个句子。如果通顺用of,不通则用for。
例如:You are nice.(通顺,所以应用of)。
He is hard.(非所表达的意思,不通,因此用for。)
一般过去时的概念:
一般过去时表示过去某个时间里发生的动作或状态;过去习惯性、经常性的动作、行为;过去主语所具备的能力和性格。
一般过去时的用法:
1、表示过去发生的动作或存在的状态,常与表示过去时间的副词如:yesterday,last week,two hours ago等连用。
如:My family moved here five years ago. 我家五年前搬到了这里。
I was born in 1973. 我生于1973年。
2、表示过去一段时间经常或反复发生的动作。这时可与频度副词如:often,usually,always等连用。
如:He always worked in tonight those days. 那些日子他总是工作到深夜。
I often left on business in 1987. 1987年我经常出差。
注:表示“过去经常,而今不再”时,要用usedto.
如:I used to read newspaper after breakfast. 我过去经常早饭后看报纸。(意指现在已不是这样)
The children often swam in this river. 孩子们过去经常在这条河里游泳。
3、表示过去发生的一连串动作。
如:He put down the heavy box, took out the keys, and opened the door. 他放下这沉重的箱子,掏出钥匙开了房门。
注:过去发生的一连串动作,若用and,or,but等并列连词连接,则一律用过去式。
如:They moved the chairs to the table, sat down and began to have supper. 他们把椅子搬到桌边,坐下开始吃饭。
4、在时间和条件状语从句中,用一般过去时表示过去将来的动作。
如:He said that he would let me know as soon as he got the information. 他说他一得到消息就立即让我知道。
Mary told me that she would stay at home if it rained. 玛丽告诉我如果下雨她就呆在家里。
一般过去时的特别用法:
1、句型:It is time for sb. to do sth "到……时间了" "该……了"。
例如:It is time for you to go to bed.你该睡觉了。
It is time that sb.did sth. "时间已迟了" "早该……了"。
例如:It is time you went to bed. 你早该睡觉了。
2、would(had)rather sb.did sth. 表示'宁愿某人做某事'。
例如:I'd rather you came tomorrow. 还是明天来吧。
3、wish, wonder, think, hope等用过去时,作试探性的询问、请求、建议等,而一般过去时表示的动作或状态都已成为过去,现已不复存在。
例如:I thought you might have some. 我以为你想要一些。
比较:Christine was an invalid all her life.(含义:她已不在人间。)
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 any thing 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:Could you lend me your bike? 你的自行车,能借用一些吗?
it的概念:
it可用作人称代词、指示代词、先行词及引导词等。
it 的用法:
1、it可指天气、温度、时间、距离等 。
如:It is cold today, isn't it?
2、用作人称代词,代替前文提到过的事物。
如:The dog is not acold-blooded animals. It doesn't need to hibernate.
3、为避免重复,it可用来代替前面说过的短语或句子。
如:I tried to persuade my father to give up smoking, but found it impossible. (it=to persuade my father to give up smoking)
4、代替指示代词this,that。
如:—What's this?
—It's an album.
—Whose new bike is that?
—It's Mary's.
注:it与one,that的区别:
it=the(this, that)+名词,特指并且代替前面所提到的某特定事物。
如:He's bought a new car, so he drives it everywhere to show ito ff.
one=a+名词,one指前面提到的同类事物中的不同的另一个。
如:He needs a computer, but he can't afford one.
that=the+名词,that指代的名词与前面的名词属于同一类,但不属同一个。
如:The population of China is larger than that of Japan. that指代population,但其后有一个of短语作定语,以区别于the population of China。
注:it与that的异同:
it指同一事物,that指同类但并不是同一事物。
如:I like the climate of Kunming more than that of Beijing.
The climate of Kunming is mild, and I like it.
5、It/This/That+be+the first(second, third...) time+that-clause 这个句型表示截止到说话时为止的某人的一种经历,关键是注意time前有序数词,主句是一般现在时is时,从句要用现在完成时;如果主句用一般过去时was时,则从句须相应地用过去完成时。
如:This is the first time(that) these Europeans have visited the Great Wall.
It was the fifth time(that) I had paid a friendly visit to America.
6、在一些相对固定的词组中,没有特殊含义,经常不翻译。
如:He's never really made it as an actor. 作为演员,他从未获得过真正的成功。
It is my turn. 轮到我了。
强调句中的it:
可以用来改变句子结构,使句子的某一成分得到强调:
1)强调句的基本句型it's/was+被强调成分+that/who+其他成分
原句:I told Jim the news in our office yesterday.
强调主语:It was I that/who told Jim the news in our office yesterday.
强调宾语:It was Jim that I told the news in our office yesterday.
或:It was the news that I told Jim in our office yesterday.
强调地点状语:It was in our office that I told Jim the news yesterday.
强调时间状语:It was yesterday that I told Jim the news in our office.
2)强调句的一般疑问句型Is/Was+it+所强调部分+that/who...?
如:Was it you that told Jim the news in your office yesterday?
3)强调句的特殊疑问句型疑问词+is/was+it+that/who...?
如:Who was it that told Jim the news in your office yesterday?
【注】强调句与主语从句虽然在形式上很相似,即都含有it is(was)...that。但,区别在于:强调句去掉it is(was)…that之后,句子结构仍然完整,而主语从句却不能这样。
如:(It is)our hope(that) the two sides will work towards peace.
解析:去掉It is…that之后,句子是不成立的。由此得出该句不是强调句,而是一个简单的主语从句,it是形式主语,从句是真正的主语。
“it”的用法:
1、it 作形式主语:
it 在句中可作形式主语,而真正作主语的主语从句需要放在句子的末尾。主语从句后置常用以下几种结构:
1)It is/was+adj.+subject-clause可用于此句型的形容词有:
clear, certain, funny, good, impossible, likely, natural, obvious, possible, probable, strange, surprising, true, unusual, wonderful等。
如:It is obvious that going for sports will do a lot of good to your health.
2)It+be+adj./n.(forsb./ofsb.)+todosth. 该句型中的形容词通常表示事物的特点或特征的,如:
difficult, hard, easy, impossible, necessary, important等,此时用for;或表示人的性格特征或特点的,如:
nice, good, bad, kind, silly, foolish, wise, clever, careless, rude, brave, cruel, careful, grateful等,这时要用of 。
3)It is/was+名词词组+subject-clause可用于该结构的名词词组有:
a pity/duty, a good thing, no surprise, good news, an honor, a fact, a mystery, a shame, manners等。
如:It's a pity that I didn't attend the party.
4)It is/was+V-ed+subject-clause可用于该结构的动词的过去分词有:
said, reported, thought, supposed, believed, hoped, expected, known, decided, announced, arranged等。
如:It is said that something had been done to end the pollution.
注:本句还可改写为:Something is said to have been done to end the pollution.
5)It+vi.+subject-clause可用于该结构的动词有:appear, seem, happen, occur等。
如:It appeared to scientists that the stars had moved.
6)It doesn't matter(makes no difference,etc.) +连接代词或连接副词引起的从句作宾语。
如:It doesn't matter whether he'll join the army or not.
It makes no difference where we have the conference.
7)一些固定句型:
It takes sb. some time to do sth.
如:It will take you two days to get there on foot.
It costs sb. some money to do sth.
如:It costs 1,000 dollars to fly to America.
It is/was no use(useless) doing(做什么是没有用处的)
如:It's no use arguing with him.
It is/was no good doing(做什么是没有好处的)
8)以下句型结构中需要用虚拟语气
① It is/was important(necessary, strange) that...;
It is/was ordered(required, suggested, proposed) that...;
It is/was a pity(a shame) that...表示遗憾等感情的句子中,主语从句要用“should+动词原形”,should可以省略。
如:It's necessary that he(should) be operated on at once.
② It is (high)time that...结构中用should+动词原形(should不能省略)或动词过去式。
如:It is high time that you should make(made) full use of your time to go over your lessons.
2、it作形式宾语:
1)动词consider(feel, find, think等)+it+形容词(名词)+不定式(动词-ing形式,从句)。
如:She thinks it no use telling me.
2)主语+appreciate(enjoy,like,love,hate)+it+if(when)...结构
如:We would appreciate it if you could come to help us.
3)dependon, relyon, see to(负责/设法做到), takeforgranted(习以为常)等短语后跟that从句时,要以it作形式宾语。
如:We're depending on it that he will finish the job by Friday.
“it ”引起的几个易混淆的时间句型:
1)It be+时间+since-clause 这个句型表示从since从句谓语动作发生以后到现在或过去所经过的一段时间,意为“自从…以来已多久了”,主句多用一般现在时,从句用一般过去时,如果表示过去的情况,主句一般用过去时,从句用过去完成时,或主句用过去完成时,从句用一般过去时。
注:since引导时间状语从句时,从句若使用终止性动词,则表示该时间是主句时间段的终点(时间从现在算起);若从句使用延续性动词,则表示该动作状态的结束(时间从过去算起)。
如:It's five years since they got married. 他们结婚已经5年了。
It's five years since they were married. 他们离婚已经5年了。
It's ten years since his father was a worker. 他父亲不当工人已经10年了。
I haven't seen him since we were boys together. 我们长大以后再没有见过面。
2)It be+时间+before-clause 这个句型中的时间一般为表示一段时间的词语(如:long years, months, weeks, days, hours, minutes),主句中的谓语动词用肯定式,意为“过多长时间才…”。主句的谓语动词是否定式时,意为“没过多长时间就…”。主句的时态可用过去时was或将来时willbe;用was时,before从句的动词用一般过去时;用willbe时,before从句常用一般现在时。 如:It was not long before she learned those poems by heart. 她没过多久就背会了那些诗。
It was long before the police arrived. 过了很久警察才来。
It will be hours before he makes a decision. 要过好几个小时他才会作出决定。
It will not be hours before we meet again. 要不了几个小时我们还会再见面的
3)It be+时间+when-clause 这个句型中,it指时间,而且表示时间的词语前没有介词(时间一般是具体时间)。主句和从句中的谓语动词在时态上是一致的,主句是willbe,when从句用一般现在时代替将来时。
如:It was already 8 o'clock when we got home.
It will be late afternoon when they get there.
4)It be+时间+that-clause 这个句型是个强调句型。
如:It was at 5o'clock that he practiced playing the violin in the morning. (原句是:He practiced playing the violin at 5o'clock in the morning.)
比较:It was 5o'clock when he started in the morning.(5o'clock前没有介词,这个是定语从句)
5)It be+time+that-clause 这个句型属虚拟语气结构,不管主句中用的是is或was,that从句都须用动词的过去式或should+动词原形(但不及物动词通常用过去式),在time之前有时可以加上high 或about 以加强语气。
如:It is high time(that) he wrote a letter to his girl friend.
It is time(that) we made people's life a little easier.= It is time that we should make people's life a little easier.
