  初中英语人教版知识点总结:动 词

  一、联系动词

  (1)表示状态的词:

  be/seem/appear/look/sound/feel/taste/smell/keep/

  remain等。

  (2)表示状态变化的词:become/get/grow/turn/fall等。

  (3)联系动词后跟形容词或名词作表语。

  二、情态动词

  (1)can :能、会,表示能力,相当于be able to,可以,表示许可,相当于may.

  区别:can没有将来时和完成时。

  Be able to可用于将来时和完成时。

  (2)may:可以,可能,或许。

  注意:may be情态动词,在句中作谓语,意为可能是。

  May be副词,在句中作状语,意为很可能,大概。

  例如:

  You may be right. May be you are right.

  (3)must:必须,一定。Must be 表示肯定的推测,准是,一定是。

  区别:must表示说话人的主观看法,意为必须。

  Have to表示外界客观愿望,意为不得不。

  例如:

  Her mother is ill,she has to stay at home and take care of her.

  You must look after your mother.

  (4)could比can 语气更婉转,客气,并不表示过去时。

  例如:could you tell me the way to the bus station?

  (5)注意回答形式:

  May I …? Yes,you may./no,you can′t(mustn′t).

  Must I …? Yes,you must./no,you needn′t.

  (6)should表示应当,应该,与疑问句连用表示以外,惊奇。

  例如:what should I do ?

  (7)will,would在交际用语中,would更客气,表示邀请。

  Shall we …? Shall用于主语是第一和第三人称的疑问句中,表示请求。

  Will you …? Will用于主语是第二人称的疑问句中表示请求。

  三、助动词

  助动词有be/do/does/did/have/has/will/would等。

  (1)助动词be用于构成进行时态,被动语态。

  (2)助动词have用于构成完成时态。

  (3)助动词do用于构成疑问句和否定句。

  (4)do位于动词前,加强说话的语气。

  例如:do be quiet,children.孩子们,务必安静点。

  (5)do用于倒装句。

  例如:only then did I realize it.到那时我才意识到这一点。

  四、实义动词(行为动词)

  (1)不及物动词:不能直接跟宾语,常须加介词后方能加宾语。

  例如:look at(for,after) get to(on,off) hear of(from) point to(at,out) worry about.

  (2)及物动词:后面必须跟宾语,意义才完整。

  例如:we study english.

  注意:在及物动词+副词构成的动副词搭配时,代词应放在中间。

  例如:turn on the radio. Turn it on.

  (3)行为动词的几种变化形式:

  规则动词:

  Enjoy(原型)enjoys(第三人称单数)enjoyed(过去式)enjoyed(过去分词)enjoying(现在分词)

  Wear-wore-worn

  情态动词及助动词:can-could/may-might/shall-should/

  Will-would/

  (4)现在分词的变化方法

  直接在动词的后面加ing work-working do-doing

  以e结尾的去e加ing, write-writing like-liking

  重读闭音节双写最后的辅音字母加ing,swin-swimming

  Dig-digging hit-hitting

  注意:lie-lying die-dying

  1、在begin/hope/start/wish/want/decide等词之后一般用动词不定式作宾语,而在ask/tell/invite/order/help等词之后一般用动词不定式作补足语。Help后可省略to.

  2、在see/hear/watch/notice/let/make/have/feel等感观动词或使役动词后作宾语补足语的动词不定式,一般要省略to.

  例如:the boss made him do heavy work.

  注意:(1)上述动词用于被动语态时,to要还原。

  例如:he was made to do heavy work by the boss.

  (2)在上述动词的后面可用现在分词作宾补,但用现在分词和动词不定式所表示的意思不同。

  I saw the boy climb the wall.我看见小孩爬墙了。(强调爬墙这件事,动作结束了)。

  I saw the boy climb the wall.我看见小孩正在爬墙。(强调爬墙的情景)

  3、had better/why not +省略to 的动词不定式。

  He did not know when to start.

  We did not know how to get there.

  5、特殊结构:

  (1)would like/love to do 想要做某事

  注意:feel like+doing sth 想要做…

  (2)it is time (for sb.)to do sth.=it is time for sth是干某事的时候了

  (3)it takes sb.…to do sth.=sb.spend…(in)doing sth.花(时间)做某事

  (4)too…+形容词+to do sth 太…以至于不能…

  (5)have…to do 有……要做(动词不定式作定语)

  例如:I have a lot of homework to do

  (6)主语+be+(感情)形容词+to +动词原形

  例如:I am glad to see you.

  (7)it+be+(品行)形容词+of+人+to+动词原形

  例如:it is very kind/nice/good of you to do so.

  (8)形容词+enough+to+动词原形

  例如:he is strong enough to move the stone.

  六、动名词

  特点:(1)无人称和数的变化;(2)在句中不能作谓语。

  1、介词后面的动词形式必须是动名词。

  例如:he sat there without saying word.

  2、只能跟动名词作直接宾语的及物动词和短语有:

  Enjoy/finish/mind/practice/suggest/avoid/excuse/keep/can not help/feel like/give up/be used to/look forward to/be worth.

  3、既可跟不定式,也可跟动名词作宾语的动词有:

  A:stop/to do sth(停下来做某事)/doing sth(停止做某事)

  例如:

  We stopped talking when the teacher came in.老师进来的时候,我们停止说话。

  We stopped to hava rest after a long walk.走了很长的一段路,我们停下来休息一下。

  B:remember/to do sth(记得去做某事)/doing sth(记得做过某事)。

  例如:

  I remember taking the medicine at the right time.我记得已按时吃过药了。(吃过了)

  C:forget/to do sth(忘记去做某事)/doing sth(忘记做过某事)

  例如:

  I forgot to tell her about it.我忘了告诉她这件事。(没告诉)

  I forgot sending the letter.我忘了发错信了。(已发过了)

  D:try/to do sth(试图)/doing sth(试着干)

  例如:

  If you can not go to sleep,try to count from 1 to100.

  Have you ever tried cooking meat in this way?

  七、动词的时态

  1、根据时间状语确定谓语动词的时态。

  与不同时态连用的时间状语如下:

  (1)一般现在时:

  usually/often/always/sometimes/everyday/month.等。

  (2)现在进行时:

  now/these days/months/this week等。When,while引导状语从句。

  (3)一般将来时:

  Tomorrow/today,tonight/in……/soon等。

  (4)现在完成时:yet/already/just/recently/ever/never以及for+一般时间短语和由since引导的表示时间的短语及时间状语从句。

  (5)过去进行时:this time yesterday/at 8:00yesterday/just now/those days等。

  (6)过去完成时:by the end of last term/before that day以及由when/before/after/as soon as等引导的表示过去时间的状语从句。

  注意:在不同的语境中,同一时间状语可能与不同的时态连用。

  例如:

  (1)he was reading a novel yesterday afternoon.昨天下午他在看一部小说。

  (2)he read a novel yesterday afternoon.昨天下午他看了一篇小说。

  2、根据语境确定谓语动词的时态

  有时句子并未列出明确的时间状语,这就需要根据所表达的意思或者前后句的联系,来确定正确的时态。

  例如:be quiet!my brother is sleeping.(sleep)

  根据“be quiet”,可以确定其后的句子应为现在进行时。

  3、根据主从复合句的关系来确定从句谓语动词的时态。

  (1)在含有宾语从句的主从复合句中,当主句的谓语动词是一般现在时时,从句可以根据需要用任何时态;当主句的谓语动词是一般过去时时,从句只能用相应的某种过去时。但从句表示永恒的真理或客观存在的事实时,要用一般现在时。

  例如:

  The teacher said that tom had passed the exam.

  He said that light travels faster than sound.

  (2)当主句是祈使句或者主句的谓语动词是一般将来时时,在时间条件状语从句中,一般现在时代替一般将来时。

  例如:

  Let is go out if it dose not rain tomorrow.

  She will see you as soon as she has time next week.

  4、词语辨析

  (1)have gone与have been的区别。

  Have gone:表示主语已离开说话者所在的地点,并且在“去”的途中或者已经到达目的地。

  Have been:表示主语去过某地又回来了。

  例如:

  He has gone to london.他去伦敦了(目前不在这儿)

  He has been to london.他到过伦敦(目前回来了)

  (2)just/just now

  Just 刚才,意为only a very short time ago与现在完成时态连用。

  例如:I have just had my lunch.我刚吃过午饭。

  注意:在非正式美国英语中,just也常常与一般过去时连用。

  She just arrived.她刚到。

  Just now意为a moment ago,通常和一般过去式连用。

  I saw her just now.我刚才看到她了。

  (3)终止性动词和延续性动词的用法。

  终止性动词和延续性动词的相应转换形式如下:

  Borrow-keep buy-have come(go)-be begin-be on finish-be over open-be open jion-be in die-be away go to school-be a student/ be in school get up

  be up fall asleep-be asleep

  例如:the old man has been dead for three years.

  His brother has been in the army since two yeara ago.

  I have kept the book for a week.

  八、动词的语态

  1、被动语态的形式。

  被动语态由“助动词+实义动词的过去分词”构成,助动词be随着人称、数、时态和语气的不同而变化。

  含有情态动词的被动语态形式:can(may/must)+be+过去分词

  (1)主语+被动动词

  被:rice is grown in the south.

  主:people grow rice in the south.

  (2)主语+被动动词+宾语(或介词宾语)

  被:I was given a book.

  主:he gave me a book.

  2、主动语态变为被动语态时应注意的几个问题。

  (1)如果主语是疑问代词,变被动语时要加介词by.

  主:who cleaned the windows?

  被:who was the window cleaned by?

  (2)如果主语不是动作的执行者,而是表示“所使用的物质材料”的名词,变为被动语态时,表示“物质材料”的名词前要加介词with.

  主:smoke filled the room.

  被:the room was filled with smoke.

  (3)如果句子中含有双宾语,变为被动语态时可以将其中任何一个宾语变为主语,另一个不变,但是将直接宾语变为主语时,要在间接宾语前加介词to.

  主:she gave me an english book.

  被:I was given an english book.(by her)或an english book was given to me(by her).

  (4)在含有make/see/hear/watch/notice等感官动词或使役动词作谓语的主动语态句子中,动词不定式在这些动词后面作宾语时,常省略不定式符号to,但变为被动语态时,to不能省略(let除外)。

  主:the teacher let me have a rest.

  被:I was let have a rest by the teacher.

  (5)如果宾语有短语或从句修饰,变为被动语态时,修饰成分应与宾语一同提前。

  主:we clean the windows of our classroom once a week.

  被:the windows of our classroom are cleaned once a week.

  (6)如果宾语是从句,变为被动语态时,一般用it作形式主语,并放在句首。而宾语从句则变为主语从句,并放在句子的最后。

  主:mary said that she would come to see you.

  被:it was said that mary would come to see you.

  (7)表示静态的及物动词have/cost/hold/know/fit等作谓语时,主动词不能变为被动句。

  例:he has a new pen.

  (8)look/become/get/turn等作系动词用时,主动句不能变为被动句。

  例:he looks fine.

  (9)直接宾语是反身代词或相互代词时,不能变被动句。

  例:he can look after himself well.

  (10)宾语是表示处所的名词时,不能变被动句。

  例:he left beijing by bus yesterday.

  (11)宾语是动名词或动词不定式时,不能变被动句。

  例:he has finished reading the book.
