2011年中考英语语法复习动词时态,英语的动词在表示不同时间里发生的行为或存在的状态时，要用不同的形式来表示，这种不同的形式叫做动词的时态。 英语常用的时态有八种，分别是：一般现在时、一般过去时,现在进行时、过去进行时,一般将来时、过去将来时,现在完成时和过去完成时。,一、一般现在时 一般现在时表示经常发生的动作（习惯性的动作）或存在的状态，句中常用always, usually, often, sometimes, seldom, never, every day等时间状语。,例如： 1、He goes to school at seven oclock everyday. 2、The sun rises in the east.,二、一般过去时 一般过去时主要用于表示过去时间，句中常有yesterday, ago, in 1989, once, last week (month, year), at that time, just now 等时间状语。,例如： 1、he was born in 1989. 2、I used to play football when I was young.,四、现在进行时 进行时表示现在时刻正在进行的动作或表示现阶段正在做的事情，句中常用now, at this moment 等时间状语连用。,例如： 1、The boy is playing video games. 2、His father is writing a novel these days.,六、过去进行时 过去进行时表示在过去某个时候正在进行的动作或过去某个阶段正在做的事情。,例如： 1、He was reading an interesting book this time yesterday. 2、When I came in, they were having supper.,三、一般将来时 英语动词表示将来时间有多种形式，其共同特点是句中常有表示见来时间的状语，如：tomorrow, next week, in a week。,例如： 1、We will visit the science museum next week. 2、We are going to discuss the problem tomorrow.,八、过去将来时 过去将来时表示从过去的观点来预计以后要发生的动作或存在的状态，这种时态常用于宾语从句当中，主句中的谓语动词一般是过去时。,例如： 1、He said that he would study harder than before. 2、He didnt tell me when he would go.,五、现在完成时 现在完成时表示从过去某一时刻开始一直延续到现在的动作或状态，或还要延续下去，句中常用：since, for, yet, already表示的一段时间状语连用。,例如： 1、Great changes have taken place in China since 1980. 2、I have finished my task.,七、过去完成时 表示在过去某个时刻前已经发生的动作，或者从过去某个时刻开始一直延续到过去另一时刻的动作和状态。,例如： 1、By the end of last year, we had learned more than 2,000 English words 2、My teacher had taught in that school for ten years before she came here.,动词时态例题选讲：,例1：Look, she (have) a bunch of flowers in her hand.,has,提示：尽管句中有look，但在英语中表示“有”，没有用进行时态，本句意思指“她手中有一束花”。,例2：John (make) much progress in his lessons since last term. He (study) harder later on. 答案：has made, will/is going to study。 提示：第一句中，since last term暗示了谓语动词要用现在完成时态。说明从上学期以来取得了很大进步，第二句中的later on要注意用一般将来时。,例3：Cherry arrived at school after the class (begin) yesterday.,提示：begin虽然也能作及物动词，但在表示某事开始时，一般以不及物动词出现，不用被动结构。,had begun,例4：If it (not rain) tomorrow, we (go) to the park.,提示：这是条件状语从句，主句是将来时，其时间或条件状语从句应用一般现在时。,doesnt rain,will go,例5:Great changes (take) place in Shanghai in the past ten years.,have taken place,提示：In the past ten years会造成过去时间感觉，但其意思是近十年中，与现在有关，要用现在完成时。,例6：It is said that they (hold) an English evening next week.,提示：主句It is said是现在时时态，从句要用将来时，不能用过去将来时。,will hold,动词时态注意的要点：,（1）将来时除了shall/will +v以外还有be going to +v，表示不久即将发生的事，be doing（用于某些动词，如leave, come, start,fly, reach,move等）；be +to +v，可带时间状语，表示“必须”； “打算”，be about +to +v，表示“即将”。例如： Hurry up! The bus is starting. We are leaving for Nanjing tomorrow.,（2）有些表示状态、感情、感觉的动词没有进行时。例如：be, have,like, want, love, hear, wash, hope。,（3）现在完成时与一般过去时都表示动作发生于过去，但现在完成时强调结果，一般过去时强调时间。例如： Have you been to the Great Wall? How long did you stay in Beijing last year?,课堂巩固练习题：用适当的动词形式填空。,1、She kept the radio when she _(do) homework. 2、She was reading newspapers.
