语法专项突破—动词分类 考点一实义动词 实义动词按照其后是否能跟宾语分为及物动词和不及物动词。 1.及物动词 及物动词就是后面必须跟宾语意义才完整的动词。如 love,need, want, ask, have, help, teach, make等。 如:We love our great motherland very much. 我们非常爱我们伟大的祖国。 My grandfather bought me a nice toy.我祖父给我买了一个漂亮的玩具。 Could you please keep the door open? 你开着门好吗? 2.不及物动词 (1)不及物动词本身意义完整,其后不必跟宾语。如 come, go, run, walk,travel,listen, swim,live,work等。 如:He works hard.他工作努力。 People often swim in the river.人们经常在这条河里游泳。 (2)如果不及物动词需要带宾语,则其后需要加适当的介词,之后才可以跟宾语。 如:The baby is smiling at us.这个小孩正对着我们微笑。 He died of hunger.他死于饥饿. 考点二 系动词 系动词的词义不完整,须与表语一起构成谓语。常用的系动词分类如下: 分类 例词 be 动词 am,is,are,was,were 感官类系动词 look(看起来),sound(听起来),smell(闻起来),taste(尝起来),feel(觉得) 变化类系动词 become,get.grow,go.turn 状态类系动词 keep,stay,remain 如:I'm an outgoing girl with short hair.我是一个留着短发的性格外向的女孩。 His plan sounds good.他的计划听起来很好。 Mr.Black’s face turned red.布莱克先生的脸变红了。 The shop stays open till8 pm.商店一直开门到晚上八点。 考点三 助动词 助动词本身没有词义,不能单独作谓语,只能和别的动词一起构成谓语动词,表示时态、语态、语气等特征,帮助构成否定、疑问、强调、省略等。主要的助动词有 be,do,have,shall,will等。 分类 作用 be am/is/are+现在分词现在进行时;was/were+现在分词过去进行时;be十过去分词 被动语态 do 形式有do,does,did.用于构成疑问句和否定句,或用在动词前加强语气 have have/has+过去分词 现在完成时;had+过去分词 过去完成时;have+been+现在分词 现在完成进行时 will/shall will/shall+动词原形 一般将来时;would/should+动词原形 过去将来时 注意:(1)will,would,shall,should 除了表示单纯的将来时以外,更多的是用作情态动词。 (2)shall,should用于第一人称表示单纯的将来时,在现代英语中常用will,would替代 考点四 情态动词 情态动词本身有一定的意义,但没有人称和数的变化,不能单独使用,须和动词一起构成句子的谓语,表示说话的情感态度和语气。 1.can 的用法 can 的基本意思是“能;会”,其过去式为 could。can的主要用法为: (1)表示请求、许可,常用于一般疑问句,相当于may。如:Can I speak 1o Mr.Li?请李先生接电话好吗? (2)表示能力。可以用 be able to 转换。如:He can speak English. 他会讲英语。 (3)表示怀疑、猜测,主要用于否定句和一般疑问句。如:He can't be at home.I saw him in the zoo this morning.他不可能在家,我今天上午在动物园看见他了。 2.may 的用法 may 意为“可以”,过去式为might。它的要用法为: (1)表示请求或许可。如:May I come in?我可以进来吗? (2)表示可能性不大的猜测,用于肯定句。如:Mr.Wang may be at home.王老师也许在家里。 (3)表示祝福和愿望。如:may表示祝愿时,常用于比较正规的场合或书面语中。如:May you be happy!祝您幸福! 注意:“May I...?”表示许可请求时,否定回答要用mustn't或can't,而不能用 may not。 如:—May I go out and play basketball? 我可以出去打篮球吗?—No,you mustn't/can't.不,不行。 3.must的用法 (1)must“必须;应该”,表示义务、命令或必要,其否定形式mustn't意为“不应该;不允许”,表示禁止做某事。如:You must be careful next time.下 次你一定要小心。 You mustn't take photos here.你不许在这儿拍照。 注意:must 的一般疑问句,肯定回答时用must或have to。否定回答时,则须用needn't 或don't/doesn't have to,而不能使用mustn’t。 如:—Must I finish the homework today?我今天必须完成作业吗? —No,you needn't/you don't have to.不,没有必要 (2)表语气较为肯定的推测。如: must be+表语 对现在情况的推测 must be十现在分词 对正在发生的情况的推测 must have+过去分词 对过去情况的推测 He must be in the room.他一定在房间里。 She must be working in the field.她一定还在地里干活。 He must have watched TV yesterday.他昨天一定看电视了。 4.have to的用法 have to意为“必须;不得不”。当主语是第三人称单数时要用 has to。 (1)have to侧重于强调客观条件需要做的事情。 It's raining,and I have to stay at home.外面在下雨,我不得不待在家里。 (2)have to 不能直接构成否定句或疑问句,需要借助于助动词。以一般现在时为例,需要借助于do或does。 如:What does she have to do? 她必须做什么? You don't have to help her with her homework你没有必要帮她做家庭作业。 5.need的用法 need 除可以作实义动词之外,还可以作情态动词意思为“需要;必须”,无人称、数、时态的变化, (1)need通常用于否定句中。 如:We needn't spend too much time on it. 我们没有必要花那么多时间在它上面。 (2)need 还可以用在一般疑问句中,肯定句用must,否定回答使用 needn't。 如:—Need I go there now?我需要现在去那儿吗?—Yes,you must.是的,你必须去。—No,you needn't.不,你不必去。 6.shall与 should 的用法 (1)shall 常用于主语是第一人称的疑问句中,表示 请求。对 Shall I...?作肯定回答时,用 Yes,please;否定回答用 No,thank you。 如:—Shall I turn on the light?要不要开灯?—Yes,please.是的,开吧!/No,thank you.不,谢谢! (2)对 Shall we...?作肯定回答时,如果不包括对方,用Yes,please;如果包括对方,则用Yes,let's. —Shall we have some bananas?我们可以吃点香蕉吗?—Yes,please.是的,请。(不包括对方) ②—It's getting late. Shall we go? 天晚了,咱们走吧?—Yes,let's go.好,咱们走吧。(包括对方) 考点五 动词短语分类 一些动词与介词或副词等组合在一起构成动词短语。多数动词短语在意义上相当于一个实义动词。 初中阶段常见的动词短语主要有以下四类: 1.动词介词 这类动词短语后跟宾语时,无论宾语是名词(词组)还是代词,都需置于介词之后。常见的这类短语有look for(寻找.寻求),wait for(等待),send for(派人去请),look after(照顾;照看),take after(与相像).come from(来自),hear from(收到..来...信).think about(思考),depend on(依靠)等。如:I have to look after her at home. 我不得不在家照看她。 He is thinking about this question. 他正在思考这个问题。 2.动词十副词 作及物动词的有 cheer up(使振奋),clean up(打扫干净),put up(建立;张贴),fix up(修理),work ou(制定出;算出),give out(发放),give away(赠送分发),think over(仔细考虑),hand in(交上)等。作不及物动词的有get up(起床), come back(回来),get down(下来),hold on(等一等;别挂断),look out(当心),run away(逃跑)等. 注意:作及物动词时,如果名词作宾语,可以放在动副词组的后边,也可放在中间。但人称代词作宾语时,人称代词要放在中间。 如:He took off his coat. = He took his coat off.他脱下他的大衣。I can cheer her up.我能让她高兴起来。 3.动词副词十介词 这类短语动词后跟宾语时,宾语置于介词之后,常见的这类短语有 add up to(合计达),catch up with(赶上), get along with(与相处),run out of(耗尽;用光),keep away from(避开;不接近),look forward to(期盼)等。 如:He is trying his best to catch up with the other students in the class.他正在竭尽全力赶上班里的其他同学。 4.动词名词介词 常见的有:make fun of(取笑),make use of(利用),pay attention to(注意),take care of(照顾)等。 5.动词+名词 常见的有:take place(发生),make friends(交朋友)等。 自我检测 1.This book be Jim's.His name is on it.
