e.g. Your shoes are too dirty. They need ________.(wash)You look tired. You need ________ a good rest. (have)

动词填空的解题思路

首先判断有无动词的固定搭配,比如:ask sb ________, finish ________

如果没有动词搭配,然后看是否有明显的时间状语标志,比如:看到now一般用________。

如果上面两者都没有,可以从上下文去推断该用什么时态。比如:Don’t make any noise. The baby ______ (sleep)

注意点:

看清单复数(尤其是一般现在时的三单式),主动还是被动语态,肯定还是否定

祈使句有两种形式,动词原形开头和don’t动词原形开头Come here./Don’t go there.

两种从句的不同,根据需要选用不同的时态。I’ll call you if I ________ there tomorrow. (get)They won’t begin the meeting until he ________. (come)Don’t write to him until he ________ there.(arrive)I don’t know if he ________ to Nanjing next month.(fly)I’m not sure when he ________ to Nanjing.(fly)

在宾语从句中

A.若主句用一般现在时,则从句可根据实际情况用各种时态。如:

The radio says the snow later in the day. (stop)I know who the fewest yesterday.(pick)

B.若主句用一般过去时,则宾语从句要依情况用过去的某种时态:一般过去时,过去将来时,过去进行时,过去完成时。如:

He said that they to the Great Wall. (be)

Mary told me that she for Paris the next day. (leave)

C.无论主句是什么时态,宾语从句中客观真理都用一般现在时。

The teacher said the earth around the sun.(move)

(5) 在完成时中,要注意瞬间动词与延续性动词的转换。如:

They borrowed the book two weeks ago. They have kept the books for 2 weeks.

buyhave, joinbe in / be a member of…, leavebe away, arrivebe here, beginbe on,

come back be back, die be dead, fall asleepbe asleep, get upbe up, finishbe over

Our classroom __________(clean) every day.

How often __________ your clothes ______________(wash)? Every two days.

英语16种时态详解

英语的16种时态 时态(Tense)是表示行为、动作和状态在各种时间条件下的动词形式。因此,当我们说时态结构的时候,指的是相应时态下的动词形式。 1. 一般现在时 英语时态分为16种:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时。 用法:A) 表示现在发生的动作、情况、状态和特征。 B) 习惯用语。

C) 经常性、习惯性动作。 例:He always helps others. (他总是帮助别人。) D) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现在时,则无法保持主句、从句时态一致。 E) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词)可以与表示未来时间的状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。 例:The next train leaves at 3 o'clock this afternoon. (下一趟火车今天下午3点开车。) How often does this shuttle bus run? (这班车多久一趟?) F) 在时间和条件状语从句里经常用一般现在(有时也用现在完成时)表示将来事情。 例:When you have finished the report, I will have waited for about 3 hours.(等你完成这份报告的时候,我就已经等了将近3个小时了。)2. 现在进行时(be doing) 用法:现在正在进行的动作。 3. 现在完成时(have done) 用法:A) 表示动作到现在为止已经完成或刚刚完成。 例:I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 B) 表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for加一段时间,或by加一个现在时间。 例:Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是:“虽然牛顿是个伟大的人物,但他的许多见解直到今天还在受到挑战,并且被现代科学家的工作所修正。”challenge是及物动词,在本句中应当是被动语态;其动作延续到今天,所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging 都是主动语态,不可能是答案。B) may be challenged虽然是被动语态,但意思与全句内容不合,所以不对。 C) 表示发生在过去,但对现在仍有影响的动作或情况。通常用点动词,如:arrive, begin, find, give, lose等。

初中英语八大时态总结

初中英语八大时态总结 一、一般现在时 具体情况(主要用于下面几情况) 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 在这种情景中,句子常带有表示频率的时间状语:always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等,以表示句中的动作或状态是习惯性的、经常性的。例如: They raise ducks as a sideline .他们以养鸭为副业。 It seldom rains here .这儿很少下雨。 2)仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态",其重点"不是强调动作发生的时间、或进行的状态"。例如: He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。 3) 陈述客观事实、客观真理。 顾名思义,客观的情况是"没有时间概念"的;也"不会在意动作进行的状态"。例如: The sun rises in the east .日出东方。 4) 根据英文语法规定,当主句的谓语动词是一般将来时,那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如: I'll tell him the news when he comes back. 他回来时,我将告诉他这个消息。 *【用于一般现在时的副词,除了上面提到的一些表示频率的以外,常见的还有:now, today , nowadays等等】 二、一般过去时 具体情况(主要用于下面几情况) 1.主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。 例:I was very thin in my childhood. 2.一般过去时由谓语动词的过去式表示,也就是说动词词末要加-ed(除不规则动词外)。常和一般过去时连用的过去时间状语有:last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。 例:Did you meet yesterday? He left just now. 3.使用一般过去时,在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。"过去"的时间概念有两层意思:一是指"现在某个时间"以前的时间;二是指"说话、写文章的那个时间点"以前的时间 He got his driving license last month. 他上个月拿到了驾照。
