语法专题十、时态(必考) 时态,顾名思义,“时”就是时间,“态”就是状态或形态。注意时态是英语动词的一个语法概念。【拓展】汉语只有时没有态。例如:我正在学习;我昨天学习;我明天要学习。这三句话里的动作发生在不同时间即“正在”、“昨天”、“明天”。而三句话里的谓语动词都是“学习”,这个动词的形态一致,没有发生改变,故汉语里的动词没有态的概念。时态:说明一个动词的发生时间,每种时态对应一个时间段,谓语动词也要有相应的变化形式。初中阶段会遇到八大时态,要求我们必须掌握的有六种时态(过去将来时和过去完成时很少考):现就各种时态的概念(定义或用法)、时间状语标志词、基本结构、动词变化规则等方面进行详细讲解。 一、 一般现在时1.概念:①表示经常性、习惯性发生的动作或存在的状态。I like playing basketball. ②表示客观真理、科学原理、自然现象。The earth goes around the sun.③在复合从句中,若主句为一般将来时,时间和条件状从常用一般现在时表将来。 例:If it doesn’t rain, we will go to the zoo tomorrow.2.时间标志词:always, usually, often, sometimes, seldom, never, every day (week, month, year…), once a week, on Sundays, at weekends等等。3.基本结构:①主语+am/is/are ②主语+行为动词原形/动词三单形式(do/does)4.动词三单形式变化规则:一般在动词后+stalk-talks ,write-writes, run-runs以s, x, sh, ch结尾+esWash-washes, watch-watches, teach-teaches以辅音字母+o结尾+esgo-goes, do-does以辅音字母+y结尾,变y为i再加es,但是以“元音字母组合+y”结尾的词直接加sstudy-studies, try-tries, carry-carries, stays, says, plays 二、一般过去时1.概念①表示过去某个时间发生的动作或状态。 I saw him yesterday.②表示过去经常发生的动作。Did he often walk to school last term?2.时间标志词:three days ago, yesterday, the day before yesterday, last night (week, month, year…), in 1989, just now, at the age of 15, once upon a time, used to do sth(过去常常做某事)… 。3.基本结构:①主+was/were②主+行为动词过去时(did) 4.动词过去式(-ed)变化规则:一般在动词后+edanswer-answered, help-helped, played以不发音的字母e结尾+dmove-moved, use-used, notice-noticed以辅音字母+y结尾,变y为i再加edcarry-carried, reply-replied, study-studies重读闭音节以元音字母加一个辅音字母结尾,双写这个辅音字母,再加edstop-stopped, plan-planned, drop-dropped不规则动词过去式(外研版九上课本P159-P162) 三、一般将来时1.概念① 表示将要发生的动作或存在的状态,及计划、打算做某事。例 I am going to have a picnic this weekend. I will come to see you tomorrow.② 现在进行时(be+v-ing)表将来,常用于表示位置移动的动词,如,come, go, leave, start, arrive, fly等。例 I am leaving for Beijing tomorrow.2.时间标志词:in three days, tomorrow, the day after tomorrow, next day (week, month, year…), soon, in the future, in 2020等等。3.基本结构:主+am/is/are+going to+do主+will+do 四、过去将来时 概念:过去将来时,表示从过去某一时间来看将来要发生的动作或状态。结构:① 主语+was/were going to +动原② 主语+would+动原(对比一般将来时be going to do; will do,过去将来时就是把be动词和will变成过去式)例I didn’t know if he was going to come. 我不知道是否他会来。He said he would stay with us. 他说他会和我们待在一起。 五、现在进行时1.概念① 表示此时此刻或现阶段正在进行的动作。The girl is listening to music now.②句中出现Look! Listen! 后面句子用进行时。③ 表示位置移动的词,用进行时表将来,如,come, go, leave, start, arrive, fly等。Don’t worry. He is coming soon. Look! Peter is watching TV.2.时间标志词:now, at the moment, these days 等3.基本结构:主+am/is/are+doing4.动词-ing变化规则(现在分词)一般直接在词尾加ingplay-playing, sing-singing以不发音e结尾,去e再加ingtake-taking, make-making, have-having以“辅元辅”结尾的重读闭音节,双写末尾的这个辅音字母,再加ingstop-stopping,shop-shopping,drop-dropping, swim-swimming,run-running, begin-beginning特殊变化lie-lying, die-dying, tie-tying常考的双写加ing的动词:shop, stop, drop, run, get, sit, dig, put, begin, swim, chat, prefer等 六、过去进行时1.概念:表示过去某个时刻或某段时间正在进行或持续的动作。例 I was writing a letter to my friend at nine yesterday. My mom was cooking when I arrived home.2.时间标志词:at this time yesterday, at that time, at seven yesterday, just then, those days, when引导的谓语动词是一般过去时的时间状语。3.基本结构:主+was/were+doing 七、现在完成时1.概念:① 表示过去的动作对现在有影响:从过去开始,现在已完成或未完成;用次数表示经历或者表示到目前为止量的积累。例Tom has just finished his homework. I have never been to the Great Wall. I have been to the Great wall three times. We have learned 1,000 words so far.② 表示从过去开始,持续到现在的动作或状态,常与since, for 连用,动词用延续性动词。对since/for短语提问用how long(多久)。例 I have lived here since 2012. I have been here for 5 years.区别:since+时间点;for+时间段。since+过去某个时间点(自从……)I have lived here since 2012.since+时间段+ago I have lived here since 10 years ago.since+过去时从句 I have lived here since I moved here in 2012.注意:短暂性动词(瞬间动词;非延续动词)可以用于完成时,但是不能与延续性的for、since连用。补充:区分动词延续不延续,可以在前面加“一直”,说得通就是延续性动词,说不通就是非延续性动词。【拓展】常见的现在完成时非延续性性动词转延续性动词的规律如下:(1)、用意义相同或相近的延续性动词替代。如: borrow→keep, buy→have, become →be, get up→be up, fall ill →be ill, fall asleep→ be asleep, get/catch a cold→have a cold (2)、用“be+形容词”替代。如: die→be dead, open→be open, end/finish → be over, (3)、用“be+介词或副词”替代。如: leave→be away, begin/start→ be on, join→be in/be a member of, come→be in/here, go→be away/out/there, reach/arrive/get to→stay/be in , come back→be back , 等等。2.时间标志词 already(已经,肯), just(刚刚,肯), yet(“还没”,用在否定句和疑问句), ever(曾经), never(从不), before(以前), recently(最近), lately(近来),so far(到目前为止), in the past/last few years(在过去几年里)等。3.基本结构:主+have/has+done4.动词过去分词的变化规则:规则的同动词过去式,不规则的单独记(九上课本P159-P162)5.短语辨析have/has been in 在某地多久了(现在还在)He has been in Shanghai for ten years.他来上海十年了。have/has been to 曾去过某地(几次)(已经回来了)He has been to Shanghai three times.他曾去过上海三次。(现在说话的时候不在上海)have/has gone to 已经去了某地(还没回来)He has gone to Shanghai and hasn’t come back yet.他已经去上海了,现在还没回来。 八、过去完成时1.基本概念(1)表示在过去某一时刻或动作以前完成了的动作,即“过去的过去”。与现在没有关系。基本结构是“had+done”。就是把现在完成时的have/has变成had,再加动词过去分词(用done来表示)。By nine o’clock last night, we had got 200 pictures from the spaceship.到昨晚9点钟,我们已经收到200 张飞船发来的图片。(2)表示由过去的某一时刻开始,一直延续到过去另一时间的动作或状态,常和for, since构成的时间状语连用。和现在完成时延续性表达一样,此种表达中的谓语动词要用延续性动词。He said he had worked in that factory since 1949.他说自从1949年以来他就在那家工厂工作。2.基本结构:主语+had+done(过去分词)①肯定句:主语+had+过去分词+其他.②否定句:主语+had+not+过去分词+其他.③一般疑问句:Had+主语+过去分词+其他?肯定回答:Yes,主语+had否定回答:No,主语+hadn't④特殊疑问句:特殊疑问词或词组+一般疑问句?⑤被动语态:主语+had(hadn't)+been+过去分词+其他 中考中主要考查六大时态(除了过去将来时和过去完成时),判断时态,最重要的是结合时间状语以及语境准确判断所应使用的时态,然后确定相应时态的基本结构。 时态类型动词结构(肯定式)一般现在时主+be动词(am is are)主(非三单)+do(原形)主(三单)+does(三单形式)一般过去时主+was/were主+行为动词过去时(did)一般将来时主+am/is/are+going to+do主+will+do过去将来时主语+was/were going to +动原主语+would+动原现在进行时主+am/is/are+doing过去进行时主+was/were+doing现在完成时主+have/has+done过去完成时主语+had+done 中考语法—时态专项练习姓名____________ 成绩__________(共计50小题,每小题2分,总分100分)1.
