1、-高中英语动词的时态和语态讲解-第 9 页动词的时态和语态用法详解 在英语中,不同时间里发生的动作或存在的状态需要用动词的不同形式表示出来,动词的这种不同形式就构成了动词的时态。英语中的时态按动作发生时间分为现在时态、过去时态、将来时态一、时态的分类和基本构成形式现在时一般现在时do/ does现在完成时have/has done现在进行时am/ is/ are doing现在完成进行时have/has been doing过去时一般过去时did过去完成时had done过去进行时was/were doing过去完成进行时had been doing将来时一般将来时will/ shall do

30、话时刻而言的,过去完成时则是相对过去某一时刻而言,强调“过去的过去”发生的动作对过去某一时间的影响或持续到过去某一时间为止。两种时态建立的时间参照点不同,对过去完成时来说,这个时间参照点十分重要,它是过去完成时概念赖以建立的基础,也是和一般过去时进行区别的重要标准。She looked well when I last saw her. (过去动作或状态)When I got there, the football match had already started. (对过去的影响或产生的结果)The train had waited there for half an hour by th
31、e time we arrived. (“过去的过去”动作持续到过去某一时刻为止)2. 一般过去时和现在完成时的区别这两个时态都是谈论已经发生的事情,但是二者的差别是,一般过去时只是单独谈论过去的事情,与现在没有联系,因此只要有过去时间状语的句子只能用过去时来表达;而现在完成时所表示的动作对现在有影响,或是与现在有关,或是谈论现在以前这一段时间里发生的事情。We bought the fruit and flowers in the supermarket just now.They havent seen the teacher today.IV 时态的一致问题在英语的复合句(尤其是宾语从句
32、)中,从句谓语动词的时态往往受主句谓语动词时态的限制或影响,即主句与从句时态基本一致。1. 名词性从句与主句时态在一些名词性从句中,如果主句谓语是现在时或将来时,则从句的谓语可根据所要表达的内容要求运用各种时态;若主句谓语用过去的某种时态,则从句的谓语时态要作相应的调整。1)主句是现在的某种时态或将来的某种时态时,宾语从句里的动词可按其所涉及的时间运用任何适当的时态。I think Molly went to the doctors yesterday.。2) 主句中的动词是过去时,宾语从句中的动词一般用过去的某种时态,但如果从句叙述的是某种真理、不变的事实或对现在或将来仍然有效的事情,则从句
33、用现在的某种时态。Alva told me that he had known the news already.。in his country children under 18 cannot buy alcohol.2. 状语从句与主句时态表示时间、原因、目的、条件、结果、让步等的状语从句一般要和主句的时态一致,即主句为现在(过去、将来)的某种时态,从句一般也为现在(过去、将来)的某种时态。Youll make progress if you keep working hard. 。3. 定语从句定语从句中的动词应依照动词本身所涉及的时间选用适当的时态,不受主句的约束和限制。This is
34、 the man I saw yesterday. 。动词的语态语态是动词的一种形式,表示主语和谓语动词之间的具体关系。语态分为主动语态和被动语态:主动语态表示主语是谓语动词所表示的动作的发出者和执行者;被动语态表示主语是谓语动词所表示的动作的承受者。注意:英语中的及物动词一般都有主动语态和被动语态两种形式。主动语态是无标记的,而被动语态则是有标记的。被动语态由助动词be加及物动词的过去分词构成。助动词be随着主语的人称、数、时态和语气的不同而变化。一、被动语态的各种形式 be+done被动语态的时态、人称和数的变化主要体现在be的变化上,其变化形式与系动词be的完全一样。1. 一般现在时:a
35、m/ is/ are + 过去分词Mary is loved by all her family.2. 一般过去时:was/ were + 过去分词The letter was written in Spanish. 。3. 一般将来时:will/ shall/ be going to/ be to be + 过去分词(shall主要用于第一人称;will可用于各人称)When will the work be finished?4. 现在进行时:am/ is/ are being + 过去分词The car accident is being looken into.5. 过去进行时:was
36、/ were being + 过去分词The library was being built last year. Im not sure if it is completed.6. 现在完成时:have/ has been + 过去分词All the work has been finished by now.。7. 过去完成时:had been + 过去分词The fire had been put out when the firefighters arrived.8. 将来完成时:will/ shall have been + 过去分词Will all the photos have
37、been developed by tomorrow?9. 过去将来时:would/ should be + 过去分词The headmaster said he would be met by the mayor.二、含情态动词的常用被动句式主语+ 情态动词+ be + 过去分词 +.The computer might be repaired by tomorrow.三、常用的被动语态句式结构1. get + 过去分词结构英语中get + 过去分词也构成被动语态。其中get 与be + 过去分词结构中的be一样,都起助动词的作用。但get多用于口语,并且其后不能跟by + 执行者,这种结构
38、常用于谈论突然发生的、出乎意料的事件,如get dressed, get killed等。He got/ was drunk for the first time in his life that night.2. 非谓语动词的被动形式高考重点考察动名词和不定式的被动形式。找准非谓语动词的逻辑主语是做题的关健。The girl is afraid of being scolded by her mother.(scold和它的逻辑主语the girl之间存在着被动关系)The book seems to have been published last year.(publish和它的逻辑主语
39、the book 之间存在被动关系)四、被动语态的用法1. 强调动作的承受者:当强调动作的承受者,将承受者作为谈话的中心时用被动语态。这类句子常有一个by引导的短语说明动作的执行者,有时也可没有。This poem was written by Whitman.2. 淡化动作的执行者:当动作的执行者是泛指时(如people, one等),常用被动语态。He is suspected robbing the bank.3. 动作的执行者是无生命的事物: He was seriously wounded by a rolling stone.4. 某些习惯用法:有些习惯用法常以被动语态的形式出现。
40、I am determined to do better than Mike.五 使用被动语态的注意事项主动形式表示被动意义1. 某些连系动词,如look, feel, sound, taste, smell, appear, seem, prove等,可用主动形式表示被动意义。The trip to the beautiful island this summer sounds really exciting. 。His plan proved (to be) practical.2. 有一类经常用作及物动词的词,如burn, wash, wear, close, read, write,
41、sell, open, lock, shut,clean, draw, cut, translate等, 用于强调事物本身的特点、特征、性能等,常用主动形式表被动含义。(to blame, to let等也用主动形式表被动含义)The pen writes smoothly.Officials believe that more than one person may be to blame for the fire.3. be worth后常接动名词的主动形式表被动意义。A lot of small towns in the area are definitely worth visitin
42、g.4. need, want, require, deserve等动词后用动名词的主动形式表被动意义。(句中主语是动名词意义上的宾语。若动名词是不及物的,其后应加相应的介词。Most house plants require regular watering.The boy is always ready to help others and deserves making friends with.5. 有些形容词后接不定式作状语时,常用主动形式表被动意义。此类形容词有easy, hard,difficult, cheap, expensive, fit, nice, good, funn
43、y, exciting, light, heavy, dangerous, comfortable,delicious等.若不定式动词是不及物的,其后要加相应多的介词。The man is difficult to deal with.6. 有些介词短语作表语,其主动形式含有被动意义。under construction 在施工中 beyond belief 令人难以置信beyond ones reach 鞭长莫及 beyond ones control 失控beyond our hope 我们始料不及 for sale 出售for rent 出租 in print 在印刷中The quest
44、ion is now under discussion.The rumor is beyond belief. ( cant be believed).注意:不用于被动语态的情形系动词、不及物动词(短语)无被动语态,常见的有appear, disappear, die, end (vi. 结束),fail, happen, take place, break out, occur, last, lie, remain, sit, spread, come true, fall asleep,keep silence, lose heart等。The meeting lasted five hours before it ended.被动形式表示主动意义,这些 done的形态的动词形容词性化。be seated, be lost, be drunk, be dressed, be devoted,be determined, be worried, be located, be exposed , be involved等表示状态
