(1)程度副词主要用于修饰形容词和副词,有的还可修饰比较级(如much, rather等)和最高级(如quite, much, almost等):
如:Houses are much more expensive these days. 如今的房价贵多了。
        This is quite[much] the most expensive radio here. 这是这里最贵的收音机。
:quite有时也修饰比较级,但只用于quite better(身体康复)这一表达。

如:I quite agree with you. 我完全同意你的意见。(不用fairly, pretty, very)
如:We rather like the film. 我们很喜欢这部电影。(不用fairly, pretty, very)
注:much也可修饰动词,但这通常只限于否定句或疑问句,而不用于肯定陈述句,除非其前有very,too,so等之类的修饰语:
如:She doesn't like him much. 她不太喜欢他。
        Does she much like him?/ Does she like him much? 她很喜欢他吗?
        He likes the film very much. 他很喜欢这部电影。(不能说:He likes the film much.)没有very, too, so等修饰的much有时也可能在肯定句修饰动词,但这只限于regret, admire, prefer, appreciate等少数动词,且此时的much应置于句中,而不是句末:
如:We much appreciate your invitation. 我们非常感激你的邀请。
(3)个别的程度副词(主要是quite和rather)还可修饰名词(注意词序):

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。

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。

改错:(错)I very like English.
            (对)I like English very much.
注意:副词enough要放在形容词的后面,形容词enough放在名词前后都可。
如:I don't know him well enough. 
        There is enough food for everyone to eat.
        There is food enough for everyone to eat.

              Even father was deeply moved by the film.
4)high与highly:
      high表示空间高度;highly表示程度,相当于much。

              You may speak freely, say what you like.


副词知识体系:


介词和介词短语的概念:

介词是一种用来表示词与词、词与句之间的关系的虚词,在句中不能单独作句子成分。介词后面一般有名词、代词或相当于名词的其他词类,短语或从句作它的宾语。介词和它的宾语构成介词词组,在句中作状语,表语,补语或介词宾语。介词可以分为时间介词、地点介词、方式介词和其他介词。


误用介词的三种情况:

1、多用介词:
多用介词可能是受汉语意思的影响将及物动词误用作不及物动词,也可能是受相关结构的影响而用错:
误:We discussed about the plan.
正:We discussed the plan. 我们讨论了计划。
误:Did he mention about the accident?
正:Did he mention the accident? 他提到那次事故了吗?
误:I saw her enter into the bank.

误:We should serve for the people heart and soul.
正:We should serve the people heart and soul. 我们应该全心全意地为人民服务。
误:Who controls over the factory? (但名词control可接over)
正:Who controls the factory? 谁管理这个工厂?
误:He has a great many of friends here. (比较a great number of)
正:He has a great many friends here. 他在这儿有很多朋友。

2、漏用介词:
漏用介词可能是受汉语意思的影响将不及物动词误用作及物动词,或是受相关结构的影响的影响而用错等:
误:This matter is difficult to deal. (deal with=处理)
正:This matter is difficult to deal with. 这事很难处理。
误:He is not a man to be depended.
正:He is not a man to be depended on. 他不是个可靠的人。
误:He took a cup of tea, and went on the story.
正:He took a cup of tea, and wentonwiththestory.他喝了一口茶,又接着讲故事。
误:My mother still regards me a child. (比较consider…as中的as可省略)
正:My mother still regards me as a child. 我母亲还把我当小孩看。
误:They insisted sending a car over to fetch us.
正:They insisted on sending a car over to fetch us.他们坚持要派车来接我们。
误:What he says is worth listening.
正:What he said is worth listening to.他的话值得一听。

3、错用介词:
错用介词的情况比较复杂,可能是因受汉语意思的而错,也可能是因弄不清搭配关系而错,可能是混淆用法而错,也可能是受相关结构的影响而错,可能是忽略语境而错,也可能是想当然的用错:
误:She called on his office yesterday. (call on+人,call at+地点)
正:She called at his office yesterday. 她昨天去了他办公室拜访。
误:He is engaged with a nurse.
正:He is engaged to a nurse.他与一位护士订了婚。

误:We are familiar to his character.
正:We are familiar with his character.我们了解他的性格。
误:Help yourself with the fruit.
正:Help yourself to the fruit.吃点水果吧。


介词的宾语:

 1、名词或代词作介词宾语:
如:Are you interested in history? 你对历史感兴趣吗?
        Don't worry about it. 别为它担心。
注:若是人称代词用作介词宾语,要注意用宾格。
如:No one can sing like her. 没有人能像她那样唱歌。(不能用like she)
2、动名词作介词宾语:

:过去分词用作介词宾语通常只见于某些固定结构中,如上面第1句涉及regard…as(认为…是)结构,第2句涉及take sth for granted(认为某事属实)。在其他情况下,介词后通常不直接跟过去分词作宾语,若语义上需要接过去分词(表被动),可换用“being+过去分词”:
如:He went out without being seen by the others.他出去了,没有被其他人看见。
4、从句作介词宾语:
如:He was not satisfied with what she said. 他对她说的不满意。
        I'm worried about where he is. 我担心他上哪儿去了。

但有个别介词(如except)可接that从句。
比较:I know nothing about him except that he lives next door./I know nothing about him except for the fact that he lives next door. 我只知道他住在隔壁,其它的就不知道了。

       They did nothing but complain. 他们老是一个劲地抱怨。 
       He never did anything but watch TV. 除了看电视,他从不干任何事。
:(1)介词后接不定式的情形通常只见于but, except等极个别个词。该不定式有时带to,有时不带to,其区别是:若其前出现了动词do,其后的不定式通常不带to;
若其前没有出现动词do,则其后的不定式通常带to。 
(2)介词后虽然通常不直接跟不定式作宾语,但却可接“连接代词(副词)+不定式”结构:
如:He gave me some advice on how to do it. 对于如何做这事他给我提了些建议。
6、形容词作介词宾语:
如:Her pronunciation is far from perfect. 她的语音远不是完美的。
        In short, we must be prepared. 总而言之,我们要有准备。
        Things have gone from bad to worse. 事情越来越糟。
:(1)有些形容词用作介词宾语可视为其前省略了动名词being:
如:He regarded the situationas(being) serious. 他认为形势严重。
        His work is far from(being) satisfactory. 他的工作丝毫不令人满意。 
(2)有些“介词+形容词”的结构已构成固定搭配:in full全部地,全面地,无省略地; in private私下地,秘密地; in particular特别地;in general一般地,通常地,概括地; in brief 简言之;in short总之,简言之; in vain徒然地,徒劳无益地;for fee免费地,无偿地; for certain肯定地,确切地;for sure肯定地,确切地; for short为了简短,简称;atl arge自由自在地,逍遥法外; by far…得多
7、副词作介词宾语:
如:I can't stay for long. 我不能久呆。 
        It's too hot in here. 这里面太热了。
        I looked every where except there. 除了那儿,我到处都看过了。
8、数词作介词宾语:
如:The city has a population of four million. 这座城市有四百万人口。
        He was among the first to arrive. 他是第一批到的。
9、介词短语作介词宾语:
如:Choose a book from among these. 从这些书中选一本吧。
        I saw her from across the street. 我从街的对面望见了她。
:通常可后接介词短语作宾语的介词是from, till, until, since, except, instead of等。
比较:I took it from the bed. 我从床那儿(或床上)拿的。

        Health is above wealth. 健康胜过财富。
        This knife is for cutting bread. 这把小刀是用于切面包的。
:有些介词(如because of)引出的短语通常只用作状语,不用作表语:
误:His absence is because of the rain.
正:His absence is due to the rain. 他因雨未来。
但是,若主语是代词(不是名词),becauseof引出的短语可用作表语:
如:It is because of hard work. 那是因为辛苦工作的原因。
2、状语:
如:Don't touch it with your hands. 别用手去摸它。
        Did you do this by design or by accident? 你这样做是有意的还是无意的?

        This is the best way of doing it. 这是做此事最好的方法。
        My love for you is deeper than the sea. 我对你的爱比海深。
4、宾语补足语:
如:I found everythingin good condition. 我发现一切正常。
       Her illness kept her in bed for a week. 她因生病在床上躺了一星期。
:用作宾语补足语的介词短语在相应的被动语态中则为主语补足语:
如:He was regarded as a hero. 他被看成是英雄。
5、宾语:
如:A man stepped out from behind the wall. 一个人从墙后走出来。
        He cannot spare anytime except on Sunday. 除星期日外,他抽不出时间。
6、主语:
如:Between6 and 7 suits me. 六点到七点对我比较适合。
        After the exams is the time to relax. 考试后是轻松一下的时间。
:介词短语通常不用作主语,尽管有时也像上面这样用作主语,但通常可视为是在一定的上下文中有所省略:
如:—When are we going to have the next meeting? 我们下次什么时候见面?
        —On Tuesday may be convenient. 星期二可能比较方便。
此句中onTuesday虽用作主语,但可视为是其前省略了meeting一词:
即:Meeting during the vacation may be convenient.


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。)


过去进行时的概念:

过去进行时表示在过去某一时刻或某一段时间内进行或发生的动作。其形式为was /were + V-ing。
常与表示过去的时间状语连用,如:last night, last Saturday等;或者与when, while, as引导的过去时间状语连用。


过去进行时的基本用法:  

1、主要表示过去某一时间正在进行的动作:
如:He fell asleep when he was reading. 他看书时睡着了。  
        We were expecting you yesterday. 我们昨天一直在等你。  
        He was playing while I was studying. 我在做功课时他在玩。  
2、过去进行时表示现在:  
用过去进行时表示现在主要是为了使语气委婉、客气。
如:I was wondering if you could give me a lift. 我不知你能否让我搭一下车。  
       We were hoping you would stay with us. 我们很希望你能跟我们住在一起。      
        How much did you want to spend, sir? 先生,您打算花多少钱?  
【注】一般过去时也有类似用法,但比较而言,用过去进行时显得更客气,更不肯定。  
3、过去进行时表示感情色彩:  
      与现在进行时相似,过去进行时也可表示满意、称赞、惊讶、厌恶等感情色彩,也通常与always, forever, continually等副词连用。
如:They were always quarrelling. 他们老是吵架。  
        The boy was continually asking questions. 这个男孩子老是问东问西的。  
4、动词be的过去进行时:  
      动词be的进行时也可表示过去一时的表现或暂时的状态。
如:He was friendly. 他很友好。(指过去长期如此)   
        He was being friendly. 他当时显得很友好。(指当时一时的表现)


过去进行时与一般过去时的区别:

(1)过去进行时强调动作在过去某时刻正在进行或持续,而一般过去时表示动作的完成。
如:He was writing his composition last night. 他昨晚在写作文。(不一定写完)
        He wrote his composition last night. 他昨晚写了一篇作文。(已经写完)
(2)表示过去的状态、感觉及心理活动的静态动词(如be, like, love, hate, fear, own, hear, see, know, want, notice)可用于一般过去时,但通常不用于进行时。
如:I hated it when a man spoke with his mouth full of food. 我讨厌人们说话时口里含着食物。
(3)一般过去时与always, constantly, forever, continually等连用,表示“过去经常性、习惯性的动作”;
而过去进行时与always, constantly, forever, continually等连用,表示动作的重复,常带有感情的色彩。
如: He always got up at six. 他过去总是六点起床。
          He was always thinking of his work. 他总是一心想到工作。
(4)有时过去进行时可以用来替换一般过去时,但一般过去时表示主语的行为是经过认真考虑的;
而过去进行时表示一种较随便或没有进行仔细考虑的行为。
如:I thought that he would agree with us. 我原以为它会同意我们的。
        I was thinking of persuading him to follow my advice. 我想到了要说服他接受我们的建议。

:下面几种情况不用一般过去时而要用过去进行时:
1、表示过去某一阶段暂时性的习惯动作时。
如:Tom was getting up at six o'clock every day that week. 汤姆那一周里每天都是六点钟起床。
2、与always连用表示赞美,厌烦等感情色彩时。
如:John was always coming to school late. 约翰上学总是迟到。
        LeiFeng was always doing good deeds for the people. 雷锋总是为人民做好事。
3、用来描写故事发生的情景时。
如:It was a dark night. The wind was blowing hard and the rain was falling heavily. A PLA man suddenly appeared on the river bank. He wanted to cross the river.
       那是一个漆黑的夜晚,风刮得很厉害,雨下得很大,一个解放军战士突然出现在河岸上,他想过河去。
4、when作并列连词,表示“(这时)突然”之意时,第一个并列分句用过去进行时,when引导的并列分句用一般过去时。
如:I was taking a walk when I met him. 我正在散步,突然遇见了他。
       We were playing outside when it began to rain. 我们正在外边玩,这时下起雨来了。
5、go, come, leave, start, arrive等动词可用过去进行时表示过去将来的含义。
如:I was leaving for Wuhan that day. 那天我正要去武汉。
       She was coming later. 她随后就来。


现在完成时的概念:  

现在完成时用来表示之前已发生或完成的动作或状态,其结果的影响现在还存在;也可表示持续到现在的动作或状态。其构成:have(has)+过去分词。


现在完成时共有四种主要用法:   

一、现在完成时表示影响:
该用法的现在完成时表示一个过去发生的动作在过去已经完成,并且这个过去发生并完成的动作对现在有影响或结果,同时说话者强调的或感兴趣的就是这个影响或结果,如汉语说“他已离开这个城市了”,其中的“离开”肯定发生了,它对现在的影响或结果就是“他现在已不在这个城市了”;又如汉语说“有人把窗户打破了”,显然“打破窗户”这一动作发生在过去,并且在过去已经完成了,但说话人强调的重点是打破窗户对现在的影响—窗户现在仍是破的。
如:He has left the city. 他已离开这个城市。(结果:他不在这个城市。)   
        Someone has broken the window. 有人把窗户打破了。(结果:窗户仍破着。)   
        I have lost my pen. 我把钢笔丢了。(结果:我现在无钢笔用。)   
        He has finished his work. 他把工作做完了。(结果:他现在可以做其他的事了。)   

二、现在完成时表示持续:   
该用法的现在完成时表示一个过去发生的动作或开始的状语在过去并未完成或结束,而是一直持续到现在,并且有可能继续下去(也可能到此结束),如汉语说“他在我们学校教书已有30年了”,显然“他在我们学校教书”是从30年前开始,并且一直教到现在,已经持续了30年;又如汉语说“自上个星期以来他一直很忙”,显然“忙”是从上个星期开始的,并且这一“忙”就一直忙到现在。
如:He has taught in our school for 30years. 他在我们学校教书已有30年了。   
        He has been busy since last week. 自上个星期以来他一直很忙。   
        He has worked for us ever since he left school. 他离开学校以后就一直为我们工作。   

三、现在完成时表示重复:   
即表示从过去某个时间直到现在的这个时间范围内不断重复发生的动作或情况,并且这个不断重复的动作有可能继续下去,也有可能到现在就结束。
如:How often have you seen her? 你隔多少见她一次?   
        My father has always gone to work by bike. 我父亲一向骑车上班。   

四、现在完成时表示将来:   
同一般现在时可以表示将来一样,现在完成时也可以在时间状语从句里表示将来。
如:I'll wait until he has written his letter. 我愿等到他把信写完。   
        When you have rested, I'll show you the garden. 等你休息好之后,我领你看我们的花园。


现在完成时知识体系:

 


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, sofar, 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, in1960)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.


过去完成时的概念:

过去完成时既可表示过去某个时间或动作之前所发生的事情,也可表示过去某个时间或动作之 前所发生的动作一直持续到过去某个时间。过去完成时由“had+过去分词”构成。 
如:She had leant 2000 English words by the end of last month. 
  


过去完成时的应用:

 (1)与过去完成时连用的时间状语可以多种多样,使用它的主要依据是看其是否发生在“过去的过去”。
如:He had learnt some English before I went here. 在来这儿之前我学过一些英语。
        He had written three stories by last year.到去年他已经写了三篇故事。
        We had cleaned the room when he got there. 当他到那儿时,我们已经把房子弄干净了。
        He went there after he had finished his work. 他把事做完之后,就去哪儿了。
注意:当主句跟由before, after, as soon as所引导的时间从句的动作连接很紧密时,从句也可用一般过去时。
如:He went there after he read the letter. 他看了那封信后就去那儿了。
(2)过去完成时还经常用于主句为过去时的宾语从句中。
如:He said he had been a soldier. 他说他当过兵。
        They said they had seen the film. 他们说这幕电影他们看过。
(3)在hardly/scarcely…when…,nosooner…than…两个结构中的主句通常要用过去完成时。
如:Hardly had I told her the news when she began to cry out. 她一听到这一消息就大哭了起来。
        Scarcely had he finished his supper when he went out. 他已吃完晚饭就出去了。
        No sooner had he fallen asleep than he lay down on the bed. 他一躺倒床上就睡着了。
(4)动词expect, hope, suppose, think, want等的过去完成时可用来表示未实现的计划、打算或希望。
如:I had hoped to see you. 我本希望来看你。
        He had wanted to buy a house in Beijing. 他本想在北京买栋房子。


过去完成时与一般过去时:

(1)过去完成时表示以过去某时间为起点以前所发生的动作或存在的状态,即:过去完成时强调“过去的过去”,而一般过去时只表示以现在时间为起点以前所发生的事情或存在的状态。
如:He studied there two years ago. 他在那儿学习了两年。(离现在两年)
        He said he had studied there two years ago. 他说他在那儿学习了两年。(离他说话时两年)
(2)表示过去某个时间以前所连续发生的两个或两个以上的动作时,一般用and, then, but按照动作的先后顺序连接,此时通常用一般过去时而不用过去完成时。
如:He said he went the shop and bought some food. 他说他去商店买了一些食品。
(3)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。
如:When I heard the news, I was very excited.
(4)叙述历史事实,可不用过去完成时,而只用一般过去时。
如:Our teacher told us that Columbus discovered America in1492.


一般现在时的被动语态的概念:

表示的是一般现在时态和被动语态的叠合。构成:(am/is/are +done)
如:This shirt is washed once a week. 这件T恤一周洗一次。


主动语态变被动语态的方法:

1、把主动语态的宾语变为被动语态的主语。  
2、把谓语变成被动结构(be+过去分词),根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式。  
3、把主动语态中的主语放在介词by之后作宾语,将主格改为宾格。
例如:All the people laughed at him.=He was laughed at by all people.   
            They make the bikes in the factory.=The bikes are made by them in the factory.   
记忆歌诀:
宾变主,主变宾,by短语后面跟。
谓语动词变被动,be后“过分”来使用。  

含有情态动词的被动语态:

含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带to的情态动词变成被动语态后“to”仍要保留。  
记忆歌诀:
情态动词变动,情态加be加“过分”,原来带to要保留。
例如:We can repair this watch in two days.=This watch can be repaired in two days.   
            You ought to take it away.=It ought to be taken away.   
            They should do it at once.=It should be done at once.

被动语态的用法:
  
1、不知道或没有必要说明动作的执行者是谁。
例如:Some new computers were stolen last night.一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)   
            This book was published in1981.这 本书出版于1981年。  
2、强调动作的承受者,而不强调动作的执行者。
例如:This book was written by him. 这本书是他写的。  
            Eight hours per day for sleep must be guaranteed. 每天8小时睡眠必须得到保证。  
记忆歌诀:
谁做的动作不知道,说出谁做的没有必要;动作承受者需强调,被动语态运用到。


一般现在时的被动语态:

一、被动语态的结构:
主语(动作接受者)+is/am/are+动词的过去分词+(by+动作执行者)
如:Football is played in most countries in the world.
被动语态的句型总结如下:
1、肯定句:主语+be+过去分词+(by~~).
如:The boy is called Jack.
2、否定句:主语+be not+过去分词+(by~~).
如:The baby is not looked after by his father.
3、一般疑问句:Be+主语+过去分词+(by~~)?
如:Is KingLear written by Shakespeare?
4、特殊疑问句:特殊疑词+be+过去分词+(by~~)?
如:What is this kind of sweater made of?

二、被动语态的用法:
1、要表达“被…”、“受…”、“让…”、“遭…”之类的语义。
如:The teachers are well respected. 
        The child is well loved by people.
2、强调动作承受者。
如:He is known far and wide. 他远近闻名。
3、不知道式没有必要指出动作的执行者。
如: The room is cleaned every day. 房子每天都有人打扫。
4、为礼貌起见避免提及动作执行者。
如:I wonder if I was allowed to introduce myself? 我是否可以做自我介绍?
