2019-2020年高考英语语法精讲精练精析-时态和语态时态 英语中不同时间和方式发生的动作或状态要用谓语动词的不同形式来表示，这种表示动作或状态发生时间和方式的动词形式称作动词时态。时间主要有四个主要部分，即现在、过去、将来和过去将来。动作方面也有四种，即一般、完成、进行和完成进行。中学课本中常见的时态有以下几种：时态构成用法一般现在时主语动词(单数第三人称 s或es)表示现在的特征、状态、经常性动作或客观事实等现在进行时主语 am (is，are)现在分词表示说话时正在进行的动作或现阶段正在进行的动作现在将来时(1)主语will(shall)动词原形(2)主语 am (is, are) going to 动词原形表示在现在看来将要发生的动作或存在的状态现在完成时主语have (has)过去分词(1)动作发生于过去，一直持续到现在，可以和表示持续性的时间状语连用。(2)动作发生于过去，已经完成，但这个动作对现在有影响，一般没有明显的时间状语，主要通过上下文来理解。时态构成用法一般过去时主语动词的过去式表示过去某时发生动作(包括过去习惯性的动作)或存在的状态过去进行时主语 was (were)现在分词表示过去某个时间正在进行的动作过去将来时主语 would 动词原形表示从过去某个时间看来将要发生的动作或存在的状态过去完成时主语 had 过去分词既可以表示在过去某一个时间或动作之前就发生或完成的动作，也可表示过去发生的某一动作一直持续到过去的另一个时间或动作。现在完成进行时主语have (has) been 现在分词现在完成进行时表示从过去某一时间开始一直延续到现在的动作。现在这个动作可能刚刚终止，也可能仍在进行。语态 语态是表示主语和动词之间语法关系及语义关系的动词形式，有主动语态和被动语态两种形式。 英语中的语态和时态是不可分割的，每种时态都有其相应的语态形式 语态构成例句一般现在时的被动语态主语am(is, are)过去分词The lion is considered the king of the forest as it is a symbol of courage and power.现在进行时的被动语态主语am(is, are)being过去分词My car is being repaired at present.现在将来时的被动语态主语 will(shall) be 过去分词/主语 am(is, are) going to be过去分词The new bridge will be pleted at the end of the year.现在完成时的被动语态主语 have(has) been 过去分词I am surprised that you should have been fooled by such a simple trick.一般过去时的被动语态主语 was (were)过去分词Marie Curie took little notice of the honors that were given to her in her later years.过去进行时的被动语态主语 was (were) being 过去分词I had the distinct impression that I was being followed.过去将来时的被动语态主语would be过去分词The workers scented changes that would be made in the pany.过去完成时的被动语态主语 had been 过去分词The new suspension bridge had been designed by the end of last month.一、时态 动词的时态是英语语法的重中之重，因为它们与句子结构、句子表达、语言逻辑紧密相连，无论是单选、完形、阅读还是书面表达都离不开时态。高考试题中常对以下几种情况进行考查。1.一般现在时与现在进行时的用法比较一般现在时主要表示现在的特征、状态、经常性动作或客观事实等；而现在进行时表示说话时正在进行的动作或现阶段正在进行的动作。His daughter is always shy in public and she never dares to make a speech to the public.Nick is looking for another job because he feels that nothing he does satisfies his boss. 注意：在时间状语从句和条件状语从句中，要用一般现在时表示将来意义，而不能直接用将来时态。If you run into any problems when you arrive at the airport, give me a ring.2一般将来时和过去将来时一般将来时主要用于表示在现在看来将要发生的动作或存在的状态；过去将来时主要用于表示从过去某个时间看来将要发生的动作或存在的状态。Will those teaching the children from abroad e to the headmasters office?He told me if I didnt follow his advice, something bad would happen.注意：“will (shall) do”和“be going to do” 都可表示意图。如果是事先考虑过的意图，要用 be going to；如果是说话时临时决定的，则用will。I am going to spend my holiday on Hainan Island this winter.I am sorry. I forgot to post the letter for you.Thats all right. I will post it myself.3一般过去时和现在完成时的用法比较一般过去时主要表示过去某时发生动作(包括过去习惯性的动作)或存在的状态，和现在没有任何关系，可以和表示过去的时间状语连用；而现在完成时有两种用法：(1)动作发生于过去，一直持续到现在，可以和表示持续性的时间状语连用。(2)动作发生于过去，已经完成，但这个动作对现在有影响，一般没有明显的时间状语，主要通过上下文来理解。We volunteered to collect money to help the victims of the earthquake.He is the only one of the students who has been a winner of scholarship for three years.4一般过去时和过去进行时的用法比较一般过去时表示动作已经完成或在某一时间段内发生了某事；而过去进行时则表示动作的持续性，侧重动作持续的长度。For the sake of her daughters health, she decided to move to a warm climate. I hear he was writing a book last year, but I dont know whether he has finished it.5一般过去时和过去完成时的用法比较过去完成时既可以表示在过去某一个时间或动作之前就发生或完成的动作，也可表示过去发生的某一动作一直持续到过去的另一个时间或动作。它和过去时的区别主要在于时间的参照点上。He began to learn English when he was fifteen.The little girl cried her heart out because she had lost her toy bear.6现在完成时和过去完成时的用法区别现在完成时和过去完成时都可和表示一段时间的状语连用，但现在完成时表示的是延续到现在；而过去完成时表示的是延续到过去某个时间。He had learned more than 5,000 English words when he entered the university at the age of 15.Many people have suffered much from the endless increasing price.7现在完成进行时现在完成进行时虽然不属于我们中学课本中常见的八种时态，但是在近几年的高考试题中频频出现，应该引起我们的注意。现在完成进行时表示从过去某一时间开始一直延续到现在的动作。现在这个动作可能刚刚终止，也可能仍在进行。Where have you been? We have been looking for you everywhere.二、语态在高考试题中，被动语态是重要考点之一。复习时，除了注意考查各种时态的被动语态外，还要注意以下几种情况：1短语动词的被动语态使用短语动词的被动语态时，切记不要漏掉构成短语动词的介词或副词。Children in New China are taken good care of.The sick boy is being operated on now.2“get 过去分词”形式“get 过去分词”也可表示被动语态，该结构较口语化。He got hurt when he fell off the bike last week.How do you get paid, by the day or by the hour?3主动形式表示被动意义一些表示开始、结束的动词(start, begin, close, end等)和表示主语某种属性特征的动词(read, write, sell, wear等)常用主动形式表示被动含义。The shop closes at 6 pm every day.This kind of apple tastes good and sells well.4非谓语动词的被动语态The building to be built is a new cinema.The car being repaired is mine. 高考试题探究(xx年)【xx全国卷,23】Planing so far ahead no senseso many things will have changed by next year.A.made B.is making C.makes D.has made【答案】C【考点】考查动词的时态。【解析】句意为“计划这么超前毫无意义到明年许多事情会发生变化的。”前句表示现在的情况make no sense，后句表示到将来会产生的后果will have changed。一般现在时表示主语的特征或状态。is making和has made表示具体的动作过程，故不选。因此选C。【xx全国卷,24】I wasnt sure if he was really interested or if he polite.A.was just being B.will just be C.had just been D.would just be【答案】A【考点】考查动词的时态。【解析】句意为“我不能确信他是真正感兴趣呢还是仅仅为了表示礼貌。”句前wasnt sure表明说话的起点是过去时，was really interested和was just being polite都是相一致的过去时。【xx全国卷,29】When Alice came to, she did not know how long she there.A.had been lying B.has been lying C.was lying D.has lain【答案】A【考点】考查动词的时态。【解析】句意为“当Alice苏醒过来时，她不知道她在那儿躺了多久了。”过去完成进行时主要表示持续到过去某时之前的动作。came to苏醒过来是过去时，苏醒前的情况是过去的过去，强调过去的过去里发生的事，故选A。【xx全国卷II,9】If you dont like the drink you just leave it and try a different one.
