据专家权威分析,试题“用所给动词的适当形式填空。1. The astronauts (take) good car..”主要考查你对  系动词,被动语态,不定式,分词,现在完成时  等考点的理解。关于这些考点的“档案”如下:

系动词被动语态不定式分词现在完成时

考点名称:系动词

  • 系动词
    亦称连系动词。作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语,亦称补语(形容词),构成系表结构说明主语的状况、性质、特征等情况。

  • 系动词的分类:
    1)状态系动词
    用来表示主语状态,只有be一词,例如:
    He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。)
    2)持续系动词
    用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如:
    He always kept silent at meeting. 他开会时总保持沉默。
    This matter rests a mystery. 此事仍是一个谜。
    3)表像系动词
    用来表示"看起来像"这一概念,主要有seem, appear, look, 例如:
    He looks tired. 他看起来很累。
    He seems (to be) very sad. 他看起来很伤心。
    4)感官系动词
    感官系动词主要有feel, smell, sound, taste, 例如:
    This kind of cloth feels very soft.
    这种布手感很软。
    This flower smells very sweet.
    这朵花闻起来很香。
    5)变化系动词
    这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall, get, go, come, run.
    例如:
    He became mad after that. 自那之后,他疯了。
    She grew rich within a short time. 她没多长时间就富了。
    6)终止系动词
    表示主语已终止动作,主要有prove, turn out, 表达"证实","变成"之意,例如:
    The rumor proved false. 这谣言证实有假。
    The search proved difficult. 搜查证实很难。
    His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果)

  • 系动词使用的注意事项:
    系动词本身有一定的词义,不能单独作谓语,后面必须与表语连用。复习系动词时,必须注意以下几个问题:<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />

    1.be是最重要的系动词,主语不同,be的形式也不同,且有时态的变化。

    a通常表示主语的特征、状态和身份等,后面接形容词、副词、名词、介词短语、不定式、v-ing、过去分词及表语从句作表语。

    b特别要注意be+过去分词所构成的系表结构与be+过去分词所构成的被动语态的区别。

    c前者侧重于表示主语的特征或所处的状态,通常没有由by引导的介词短语。

    如:The door was closed.

    后者侧重于强调主语是谓语动词所示动作的承受者,表示动作;句中可以用由by引导的介词短语。如:The door was closed by me.

    d还要注意be+ V-ing所构成的系表结构与be+ V-ing”所构成的进行时态的区别。

    前者侧重于说明主语具有的特征或存在的状态,也可说明主语是什么。如:My job is teaching English.

    后者侧重于强调主语正在做某事。如:Mr Wang is reading an evening paper now.


    2.
    要注意由行为动词转化成的系动词。

    a表示人体感官的系动词有soundtastelookfeelsmell等,后面接形容词;

    b表示主语从一种状态转变到另一种状态的系动词有becomegetgoturnrungrowcomefallprove等,后面接形容词、名词或 to be+形容词,become后面接单数名词时,名词前要用不定冠词,turn后面接单数名词时,名词前不用不定冠词;

    c表示主语继续或保持某种身份、特征或状态的系动词有continuekeepremainstaystand liereststay等,后面接表示状态的形容词;

    d表示判断的系动词有seemappear,后面接形容词、to be+名词或形容词、that-clause、不定式等。


    3.
    要注意系动词的固定搭配。常见的有come true, fall asleep, fall ill, go bad, come right, run wild, wear thin, turn nasty等。


    4.
    要特别注意某些动词既可以做系动词,又可以做实意动词的用法。

    系动词部分主要注意:
    其后要求接形容词,而不是副词做表语。遇到这种情况,只能先根据其意思判断清楚到底是前者还是后者,然后再对后面的词性和词义做出正确判断和选择。
    taste一词为例:

    The newly-invented soft drinking tastes quite unique.
    (这种新研制的软饮料尝起来挺独特的。
    注意:在这句话里,taste做系动词,不能使用进行时,后面接形容词。)

    The chef is tasting the fish carefully.
    (厨师长正在品尝这道鱼。
    注意:在这句话中,taste做实意动词,可以使用进行时,并且后面接副词做状语。)

  • 系动词用法点拨:
    1.系动词的进行时态应分情况讨论。
    一般地说,状态系动词无进行时态,而动态系动词有进行时态。
    但是在某些情况下,状态系动词也有进行时态,表示两个用途:
    一是表示一种短暂的、反常的状态。如:
    He is being kind.(一时而不能持久的性质)他装出和蔼可亲的样子。
    二是表示一种探询口气,使语言客气、生动、亲切。例如:
    I hope you are keeping well.(语气委婉)我希望你保持健康。
    Are you feeling any better?(语气亲切)你感觉好了些吗?
    试比较:
    Your hand feels cold.(无意识的静态性质。)你的手摸起来冰凉。
    不可以说:
    Your hand is feeling cold.(×)
    但可以说:
    The doctor is feeling her pulse.(有意识的动态动作)医生正在给她拿脉。
    The soup tastes good.(静态性质,无进行时)这汤的味道不错。
    The cook is tasting the soup.(动态动作,有进行时)厨师在尝汤的味道。

    总之,系动词有无进行时态应随系动词的意义或其语境变化而变化。
    我们在概述某一动词的进行时态时,不能笼统地说feel,smell无进行时,应指出其意义及其语用环境。
    例如smell的用法可见一斑。
    ①smell作“嗅觉”的能力时,虽是实义动词,但指的是一种性质的存在状态不能用于进行时态,常与can, could, be able to连用。
    The camels can smell the water a mile off.骆驼能嗅出一英里外有水。
    ②指“嗅、闻”的动作时,实义动词,可用于进行时态。
    The girl is smelling the flower.这姑娘正在闻那朵花。
    ③smell指“含有……气味”,“发出……气味”等事物性质时,半系动词,无进行时态。
    The dinner smells good.这饭菜闻起来真香。

    2.系动词的时态与形容词的比较级连用的问题。
    某些含有变化意义的动态系动词如get, become, grow, turn等的进行时态可与形容词的比较级连用,表示渐进过程,其意思是“越来越……”。例如:
    He is growing taller and taller.他长得越来越高了。
    Our life is getting better and better.我们的生活是越来越好了。
    The things are getting worse.情况是越来越糟了。

    3.所有半系动词的被动语态要分情况讨论。
    英语中某动词在作系动词用时,无被动语态,而作实义动词用时,才有被动语态,二者不可混为一谈。例如:
    不能说:
    The apple is tasted good.
    (因为taste此时是系动词,“尝起来”之意,指的是苹果的性质,无被动语态)
    但我们可以说:
    The apple is tasted by me.这苹果被我尝了一下。
    (taste此时指“尝一尝”这一动作,有被动语态)
    因此,在平时的英语教学和学习之 ,要有意注意半系动词在具体的语言环境中到底是系动词用法还是实义动词用法,要注意区分、识别。

    4.瞬间动态系动词能否与时间段连用的问题
    英语中某些表示瞬间意义的系动词不能与“for+时间段,since+时间点,how long until+时间,by + 时间,so far”等直接连用。例如:
    ①不能说:He has become a teacher for 2 years.
    应改为:He has been a teacher for 2 years.
    ②不能说:He has turned writer since 3 years ago.
    应改为:He has been a writer since 3 years ago.
    或It is three years since he turned writer.
    ③不能说:He got angry until his child came back home.
    应改为:He didn’t get angry until his child came back home.

    5.系动词能接几种表语(从句)
    系动词除了接adj.\n.\prep.短语,某些adv.以外,还可接以下几种表语形式:
    ①能接as if/as though表语从句的系动词有:look(看起来),smell(闻起来),sound(听起来),feel(觉得);appear(显得),seem(似乎)。例如:
    It looks as if we are going to have snow.看样子天要下雪了。
    He looked as if he had just stepped out of my book of fairy tales.
    他看来好像刚从我的童话故事中走出来似的。
    She seemed as if (though) she couldn’t understand why Laura was there.
    看来她好像不能理解为什么劳拉呆在那儿。
    It sounds to me as though there’s a tap running somewhere.
    我好像听到某处水龙头流水的声音。
    She felt as if her head were splitting.
    她仿佛觉得她的头要裂开了。
    The river appeared as if enveloped in smog.
    那条河好像笼罩在烟雾之中。
    It seems as if it were spring already.
    好像已是春天了。
    ②可用于“It+系动词+that从句”结构的有:seem, appear, 不可用be, look。如:
    It seemed that he had made some serious mistakes in his work.
    好像他在工作中犯了严重错误。
    It appeared that he was talking to himself.
    好像他在自言自语。
    ③能用不定式作表语的系动词有:be, seem, get, look, appear, prove, grow.
    Her job is to look after the children.
    她的工作是照料孩子们。
    He seems not to look after the children.
    他好像不是她的父亲。
    She looks to be a young girl of twenty year-old.
    她看起来像是一个20岁的年轻姑娘。
    He didn’t appear to dislike it.
    看不出他憎恨此事。
    My advice proved to be wrong.
    我的建议证明是错误的。
    He will grow to like this work gradually.
    他会逐渐喜欢这个工作的。
    ④能与there连用的系动词有:be, appear, seem.
    There appeared to be only one room.
    那儿好像只有一个房间。
    There seems(to be)no need to go.
    似乎没有必要走。

    6.能用两种否定形式的系动词有两个:seem, appear.
    举例说明:
    It doesn’t seem that we can get our money back.= It seems that we can’t get our money back.
    He seems not to be her father.= He doesn’t seem to be her father.
    The baby doesn’t appear to be awake.= The baby appears not to be awake.

    7.后接作表语的过去分词可构成系表结构
    能构成系表结构的系动词通常有两个:第一个是常见的be(is, am, was等);第二个是get,口语中常用。
    当二者作系动词用时,它们均表示一种存在状态,而不表示被动动作;当二者作助动词用时,后接作谓语的过去分词构成被动语态。
    Be + P.P常可以用get + P.P.来代替,但是并不是be系动词总是可以用get来代替。Get + P.P.系表结构常用于以下两种情况:
    1)表示偶然的、突发性的、意想不到的被动动作的结果或状态。
    Last night I got caught in the downpour.昨夜我被雨淋了(表示意想不到)
    The new car got scratched.新车给刮坏了。(表突发性)
    2)表示对自身所作的事。如get dressed, get lost等。
    John got injured while playing football last Saturday.约翰上周星期六踢足球时受了伤。
    They got married last month.他们上个月结婚了。
    另外,要注意区分系表结构与被动语态结构的用法。

考点名称:被动语态

  • 语态:
    是动词的一种形式,它表示主语和谓语的关系。
    语态有两种:主动语态和被动语态。
    如果主语是动作的执行者,或者是说动作是由主语完成的,要用主动语态;
    如果主语是动作的承受者,或者是说动作不是由主语而是由其他人完成的,则用被动语态。

  • 被动语态的构成:
    被动语态的基本结构:
    主语+be +过去分词(+by+动作的发出者)
    ① 一般现在时:am/is/are+过去分词
    如:Trees are planted every year.
    ② 现在进行时 am/is/are+ being +过去分词
    如:The road is being repaired. 
    ③ 现在完成时 have/has + been +过去分词
    如:The work has been finished.
    ④ 一般过去时 was/were + 过去分词
    如:The story was told by him.
    Many birds were killed last year.
    ⑤过去进行时 was/were+ being + 过去分词
    如: The new house was being painted when I got home.
    ⑥过去完成时 had +been+ 过去分词
    如: He told me that the work had been finished.
    ⑦一般将来时  will +be + 过去分词
    如:The problem will be discussed tomorrow.
    ⑧ 过去将来时 would/should +be +过去分词
    如: He said that the Christmas tree would be put up soon.
    ⑨情态动词的被动语态
    情态动词+ be +过去分词    
    如:The problem must be solved soon.
    Children should be taught to love animals.

  • 被动语态使用注意:
    1. 不及物动词无被动语态。 如:happen, break down, come out......
    What will happen in 100 years.
    The dinosaurs disappeared about 65 million years ago.
    2. 有些动词用主动形式表示被动意义。 如: write, sell, ride.....
    This pen writes well.
    This new book sells well.
    3. 感官动词或使役动词使用省略to的动词不定式,主动语态中不带“to”,但变为被动语态时,须加上“to”。
    例:make somebody do something→somebody+ be +made to do something
    see somebody do something→somebody +be +seen to do something
    A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.
    The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss.
    4. 如果是接双宾语的动词改为被动语态时,直接宾语(物)作主语,那么动词后要用介词,这个介词是由与其搭配的动词决定。
    He gave me a book.→A book was given to me by him.
    He showed me a ticket.→A ticket was shown to me by him.
    My father bought me a new bike. →A new bike was bought for me by my father.
    5. 一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词。
    We can’t laugh at him. →He can’t be laughed at by us.
    He listens to the radio every day. →The radio is listened to by him every day.
    The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.
    构成be+done.

  • 主动句变为被动句所遵循的4个步骤:
    ①把原主动句中的宾语变为被动句的主语
    ②把动词变为被动形式即be +过去分词,并注意其人称和数随主语的变化,而动词的时态则保持不变。
    ③原主动句的主语如需要则放在by后面以它的宾格形式出现(注代词的宾格),如不需要则可省略。
    ④其它的成分(定语、状语)不变。

    不用于被动语态的情形:
    ①不及物动词没有被动语态
    这类动词有take place, happen, come about, break out, appear, disappear, last,  arise等。
    例如:A fire broke out during the night.
    ②某些静态动词不用于被动语态
    这类动词有have, lack, fit, hold, suit, resemble等。 
    例如:My shoes do not fit me.
    ③宾语为相互代词和反身代词时不用于被动语态
    例如:We should help each other.

    关于主动形式表示被动意义:
    ①系动词(如look, sound, smell, feel, taste, prove等)要用主动表被动,因为系动词为不及物动词,它们没有被动语态形式。
    例如:The building looks very beautiful.
    ②当open, close, shut, lock, move, read, wash, clean, cook, cut, wear, carry 等用作不及物动词且表示主语的某种属性时,通常用主动形式表示被动意义。
    例如:The book sells well.
    ③有的动词本身含有被动意味,通常用主动形式来表示被动含义。
    例如:Her eyes filled with tears.
    ④不定式to blame, to let用作表语时,通常要用主动表被动。
    例如:Who is to blame?
    ⑤某些“be+形容词+to do”结构中的不定式通常要用主动形式表示被动意义。
    例如:The book is difficult to understand.
    ⑥不定式用于某些动词(如have, have got, get, want, need等)的宾语后作定语时,如果不定式的逻辑主语就是句子的主语,通常用主动形式表示被动意义。
    例如:Do you have time to help us?
    ⑦在too...to do sth.和...enough to do sth. 这两个结构中,若主语与其后不定式为to do sth.被动关系,则该不定式通常用主动形式表示被动意义(有时也可直接用 被动式)。
    例如:The writing is too faint to read.
    ⑧be worth后的动名词要用主动表被动。
    例如:This movie is worth seeing.
    ⑨在need, want, require等少数表示“需要”的动词后的动名词用主动形式表示被动意义。
    例如:The house needs cleaning.

    表示“据说”的三类被动句型:
    ①It is said that...句式
    例如:It is said that thirteen is an unlucky number.
    ②There is said that...句式 
    例如:There is said to be plenty of oil off our coast.
    ③sb./sth.is said that...句式
    例如:Mr. Brown is said to have died of liver cancer.

  • 被动语态各时态构成 :

    时态

    被动语态 

    一般现在时

    am/is/are+过去分词

    一般过去时

    was/were+过去分词

    现在进行时

    am/is/are being+过去分词

    过去进行时

    was/were being+过去分词

    一般将来时

    will be+过去分词

    过去将来时

    would be+过去分词

    现在完成时

    have/has been+过去分词

    过去完成时

    had been+过去分词

    情态动词

    情态动词be+过去分词

  • 情态动词的被动语态:
    一、理解含情态动词的被动语态的概念含情态动词的被动语态说明某个被动性动作所反映出的感情和态度。
    初中阶段可用于被动语态的情态动词有“can、may、must、need、should”等,
    分别表示“能够被……”,“可以被……”,“必须被……”,“需要被……“,应该被……”等。

    二、掌握含情态动词的被动语态的不同句式的变换方法含情态动词的被动语态的疑问句、否定句的变化均借助于情态动词完成。
    (一)一般疑问句直接将陈述句被动语态中的情态动词提前。如:
    Mustthisworkbedoneatonce?这项工作必须立即完成吗?
    Shouldyourhomeworkbefinishedbeforesix?你的家庭作业应在六点前完成吗?
    (二)特殊疑问句由疑问词加上一般疑问句被动语态构成。如:
    Whenmustthisworkbedone?这工作必须在什么时候完成?
    Wherecanthelostbookbefound?这本失踪的书能在什么地方被找到?
    (三)反意疑问句借助情态动词构成附加疑问部分。如:
    Thisbridgecanbebuiltnextyear,can'tit?这座桥明年能建成,是吗?
    Thisbookshouldn'tbetakenoutofthelibrary,shouldit?这本书不应被带出图书馆,是吗?
    (四)否定句在情态动词后面加上“not”或“never”即可,但“must”表“必要”时否定式为“needn't”。如:
    Thisworkneedn'tbedoneatonce.这项工作没必要立即做。Thisdustbinshouldn'tbeputhere.这个垃圾箱不应放在这儿。

    三、含情态动词的被动语态的一般疑问句的回答含情态动词的被动语态的一般疑问句的回答应保留原情态动词,
    但“must”表“必须”时,其否定回答应用“needn't”、“need”表“必要”时,其肯定回答应用“must”。如:
    —Shouldmyexercisesbefinishedtoday?我的作业应在今天完成吗?
    —Yes,theyshould.是的,应在今天完成。(No,theyshouldn't.不,不应在今天完成。)
    —Musthisexercisebookbehandedinatonce?他的练习本必须立即上交吗?
    —Yes,itmust.是的,必须立即上交。(No,itneedn't.不,不必立即上交。)
    —Needhebeoperatedonatonce?他必须立即手术吗?
    —Yes,hemust.是的,他必须。(No,heneedn't.不,他不必。)

考点名称:不定式

  • 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。

  • 动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性。
    动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出。
    这一使动者我们称之为逻辑主语,其形式如下:
    时态 主动形式  被动形式 
    一般式 (not) to do (not) to be done
    完成式 (not) to have done (not) to have been done
    进行式 (not) to be doing  
    完成进行式 (not) to have been doing  

  • 不定式的用法:
    1、不定式作主语
    例如:To remember this is very important.
    注意:为了避免头重脚轻,在许多情况下,通常都将作主语的不定式置于句子后部,而在句首主语位置使用形式主语it。
    例如:It is very important to remember this.
    2、不定式作表语
    例如:He seems to be ill.
    注意:不定式作表语主要有三种情况,一是用于seem, appear, prove等系动词之后的不 定式(尤其是to be),
    二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形,
    三是表示想法、约定、义务、命令、可能性、命运等,如: 
    You are to come when I call.
    3、不定式作宾语
    例如:I can not afford to buy a car.
    注意:
    ①不定式不仅用作动词的宾语,还可用作个别介词(but, except)的宾语。
    例如:I had no choice but to wait.
    ②当作宾语的不定式后跟有宾语补足语时,通常要用形式宾语it代替不定式,并将真正的宾语不定式置于宾语补足语之后
    例如:I find it difficult to learn Japanese well.
    4、不定式作宾语补足语
    例如:Who taught you to drive?
    5、不定式作定语
    例如:I have a question to ask you.
    注意:有的名词(如way, chance, right等)后用作不定式可换成of doing sth.
    如:It is the best way to do (of doing) it.
    但是以下名词后接不定式作定语时通常不能换成of doing sth.
    attempt  courage  decision  effort  fortune  failure  invitation  wish
    6、不定式作状语
    例如:I went to France to learn French.

考点名称:分词

  • 分词:
    就是具有动词及形容词二者特征的词;尤指以-ing或-ed,-d,-t,-en或-n结尾的英语动词性形容词,具有形容词功能,同时又表现各种动词性特点,
    如时态,语态、带状语性修饰语的性能及带宾语的性能。
    分词分为现在分词和过去分词两种,是一种非谓语动词形式。
    现在分词和过去分词主要差别在于:
    现在分词表示"主动和进行",过去分词表示"被动和完成"(不及物动词的过去分词不表示被动,只表示完成)。
    分词可以有自己的状语、宾语或逻辑主语等。

  • 现在分词构成形式:
    ①一般在动词原形末尾加ing,如do→doing、sing→singing、comfort→comforting
    ②以不发音的e、ue结尾的动词,先去e,再加ing,如dance→dancing、hike→hiking、write→writing、make→ making,take→taking
    ③以ee、oe、ye结尾的动词加ing,如see→seeing、toe→toeing、dye→dyeing
    ④以重读闭音节结尾的动词,并且末尾只有一个辅音字母,应双写这一字母,再加ing,如cut→cutting、swim→swimming
    注:结尾是x则不必双写,如relax→relaxing
    ⑤以ie结尾的动词,要把ie变成y再加ing,如die→dying,lie→lying.
    ⑥以ic结尾的动词,要把ic变成ick再加ing,如picnic→picnicking,traffic→trafficking

    过去分词构成形式:
    1.规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则:
    (1)、一般动词,在词尾直接加“ ed ”。(然而要注意的是,过去分词并不是过去式)
    work---worked---worked ,  visit---visited---visited
    (2)、以不发音的“ e ” 结尾的动词,只在词尾加“ d ”。
    live---lived---lived
    (3)、以“辅音字母 + y ”结尾的动词,将 "y" 变为 "i" ,再加“ ed ”。
    study---studied---studied,cry---cried---cried,try---tried---tried,fry---fried---fried.[1]
    (4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。
    stop---stopped---stopped  ,  drop---dropped--dropped
    (5)、以ic结尾的动词,要把ic变成ick再加ed,
    picnic→picnicked  ,traffic→trafficked
    2 、不规则动词:见不规则动词表

  • 分词用法:
    1、分词作状语   
    分词在句子中作状语,可以表示时间、条件、原因、结果、让步、伴随等。   
    分词(短语)作状语时,其逻辑主语应与句中主语相一致。
    当现在分词表示的动作发 生在谓语动词之前时, 则用现在分词的完成式,且所表示动作与谓语动作同时发生, 则用现在分词的一般式。
    完成或被动关系用过去分词。   
    ①现在分词:
    The students went out of the classroom, laughing and talking.   
    ②过去分词:
    Accompanied by his friend, he went to the railway station. 
    Given   better attention, the plants could grow better.   

    2、“while ( when, once, until, if , though等连词)+分词”结构   
    现在分词或过去分词作状语时,有时可以在分词前加while,when, once, although, until, if等连词。   
    ①现在分词:
    When leaving the airport, she waved again and again to us.
    While waiting for  the train, I had a long talk with my sister about her work……   
    ②过去分词:
    Once recovered, he threw himself into his work and made every effort to do it  well.   
    Although working very hard, he failed to pass the final exam. If translated word by word, the passage will be difficult to understand.   

    3、分词作定语   
    分词作定语时,单个的分词通常放在被修饰的名词之前,分词短语一般置于所修饰的中心词后面。
    现在分词修饰的是发出该动作的名词(即与名词有主谓关系),过去分词修饰承受该动作的名词(即与名词是动宾关系)。    
    We will go on with our experiment as soon as we get the added fund.    
    This is really an exhausting day to all of us!   
    We can see the part of the moon lighted by sunlight.   
    After a night spent in excitement and sleeplessness, I forced myself to take a long walk along the beach the next day.   
    More and more developing countries established strategic partnership with  developed countries   

    4、分词作宾语补足语   
    现在分词在see, watch, hear, observe, notice, feel, find, glimpse, glance等感官动词和look at, listen to等短语动词以及
    have, keep, get, catch, leave, set, start, send等使役动词后面与名词或代词构成复合宾语,作宾语补语的成分。
    例:I see him passing my house every day.
    I caught him stealing things in that shop.
    I smelt something burning.

    5、分词作表语
    分词作表语通常看作形容词来用。
    过去分词表示主语的感受或状态,主语多为人。现在分词表示主语的性质,而且主语多为物;
    ①过去分词:
    We were so bored that we couldn’t help yawning.
    She felt confused, and even frightened.
    ②现在分词:
    He was very amusing.
    That book was rather boring.
    很多动词的现在分词都可以作表语:
    exciting, interesting, encouraging, disappointing, confusing, touching, puzzling.

考点名称:现在完成时

  • 现在完成时:
    过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在的动作或状态。
    基本结构:主语+have/has+动词的过去分词
    句式:
    1. 否定句式:现在完成时的否定句式是“haven't (hasn't)+过去分词...”。
    如:I have not seen the movie yet. 我还没看这部电影。
    2. 一般疑问句:Have(Has)+主语+过去分词...? 如:
    —Have you finished the work?你已经做完这项工作了吗?
    —Yes, I have. 是的,我已经做完了。(No, I haven't. 不,我还没有做完。)
    3. 特殊疑问句:特殊疑问词+have(has)+主语+过去分词...?如:
    How many times have you been to the Great Wall?你去过长城几次?
    提示:肯定句中有some, already时,改为否定句或疑问句时通常要分别改为any, yet。如:
    I have already finished my homework. 我已经完成了我的作业。
    → I haven't finished my homework yet. (否定句)
    → Have you finished your homework yet? (一般疑问句)
    现在完成时常见两种句型:
    ①for短语
    ②It is+一段时间+ since从句

  • 现在完成时特点:
    1. 非持续性动词的完成时的肯定式不能与时间段连用,若要用时间段状语,则应换成相应的持续性动词或状态动词。
    例如:
    He has left.
    He has been away for an hour.
    2. have/has been to 表示曾经去过某地,但现在不在那;have/has gone to表示现在已去某地,现在不在这。
    例如:
    He has been to Canada, but now he is working in our company.
    Mr. Li in not at home. He has gone to Shanghai.
    3. 完成时的肯定式常用already,而否定式和疑问式常用yet,但若already用于疑问句时,表示一种出乎意外的惊讶。
    例如:Have you read it already?

  • 现在完成时和一般过去时区别:
    现在完成时和一般过去时都表示在过去完成的动作。
    但现在完成时强调的是这一动作与现在的关系。如对现在产生的结果或影响等,
    而一般过去时只表示动作在过去某一时刻发生,不表示和现在的关系。
    比较:
    I have lost my new book.  我把新书丢了。(现在还未找到)
    I lost my new book yesterday. 我昨天把新书丢了。(昨天丢的,现在找到与否没说明)

    have been(to)与have gone( to)的区别:
    have been(to)表示“去过某地(现在已经回来了)”,可用于各人称;
    have gone(to)表示“去某地了(说话时某人不在当地)”,常用于第三人称,
    前者可与once ,never,several times等连用,后者则不能。
    如:
    They have been to Beijing twice.他们去过北京两次。
    He has gone to Beijing .  他去北京了。

    现在完成时注意事项:
    1.如单纯表示一段时间,或强调一段时间,虽有since一词,也不必用完成时。如:
    It is two years since his father died. =His father has been dead for two years.他父亲去世已有三年了。

    2.终止性动词现在完成时的否定式,已变成一种可以延续的状态,因此可以和表示一段时间的状语连用。如:
    I haven't left here since 1997.自从1997年以来,我一直没有离开过这儿。

    3..现在完成时不能单独与准确时间连用,(如表示过去的时间状语)
    如:yesterday(morning、afternoon),last(morning、afternoon)等,除非与for,since连用.

    4.不能与when连用.

  • 现在完成时的用法:
    1.表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如:
    -Have you had lunch yet?    
    -Yes,I have. I've just had it.
    2.表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。
    常带有for和since等表示一段时间的状语。如:
    He has taught here since 1981
    他自1981年就在这儿教书。(可能还要继续教)
    I have't seen her for four years.
    我有四年没见到她了。
    3.表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”。
    常与twice,ever,never,three times等时间状语。 如:
    I have been to Beijing twice.我去过北京

    4. 现在完成时还往往可以同包括现在时间在内的时间状语连用,如:
    now,up to these few days/weeks/months/years,this morning/week/month/year,just,today,up to present,so far等:
    Peter has written six papers so far.
    Man has now learned to release energy from the nucleus of the atom.
    There has been too much rain in San Francisco this year.
    The friendly relations and cooperation between our two countries have been enhanced in the past few years.
    Up to the present everything has been successful.

    5.现在完成时往往同表示不确定的过去时间状语连用,如:
    already(肯定),yet(否定,疑问),just,before,recently,still,lately,never等:
    He has already obtained a scholarship.
    I haven't seen much of him recently (lately).
    We have seen that film before.
    Have they found the missing child yet?

    6.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?
    7.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)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: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。
    8.一段时间+has passed+since从句
    主语+have / has been+since短语
    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  
    9. 现在完成时常和短语 "up to now /till now","so far" (意思是从过去某一确定的时间一直延续到现在)连用。  
    Up to/till now he's read many story books. 至今他已读过好多故事书。
    I've been to New York three times so far. 至今我已到纽约去过三次。
    has gone (to),has been (to),has been (in) 的区别
    has gone to:去了没回
    has been to :去过
    has been in:呆了很久
