一. 内容： 动词的时态语态专项练习 二. 重难点讲解： 动词的时态和语态 在接下来的时间里将给大家介绍一下动词的时态和语态。 到目前为止大家应该知道，动词共有16种时态和两种语态。 在时态方面，考题中主要涉及到其中的10种：一般现在时、一般过去时、一般将来时、现在进行时、现在完成时、过去将来时、过去进行时、过去完成时、将来进行时、将来完成时、现在完成进行时。 1. 一般现在时：通常有六种用法，其中最重要的考点是：在时间或条件状语从句中表示将来的动作；安排或计划好的将来发生的动作。 如：1>. The train for Shanghai leaves at 11a.m and arrives at 11p.m. 2>. As soon as the manager comes back, I will tell him about it. 2. 一般过去时： 关于该时态最主要请大家掌握它的概念：一个开始于过去结束于过去的动作，或存在的状态。记住这一点很重要，需要与现在完成时区分。 如：The other day she ran across an old friend in the street. 3. 一般将来时： 除了用will + 动词原形表示该时态外，还有： 1> Be going to do sth： She is going to go abroad next year. 2> Be about to do sth： Please fasten your safety belt, for the plane is about to take off. 3> Be to do sth： There is to be a class meeting this afternoon. 4. 现在进行时： 除了众所周知的表正在进行动作外，还有如下特殊用法： 预计一个将要发生的动作；常与某些副词连用，表示某种感情色彩，如赞叹、惊讶或不满。 如：1> How many of you are going to the party tonight. 2> The teacher is always criticizing us. 5. 现在完成时：这应该是五个基本时态中最令大家迷惑的一个。该时态分为已完成和未完成两种。常见的标志性的词有：since, for, already, so far, up to now, in the last few years, in the past three months etc. 如：1> He has lived here since he got married. 2> In the past two decades, research has expanded our knowledge about sleep and dreams. 3> In the last ten years great changes have taken place in China. 6. 过去将来时：只有一个考点：用于主句的谓语动词是过去时态的间接引语中，遵循时态呼应原则。 如：she said she would pay us a visit when she had enough time. 7. 过去进行时：表示在过去的某个时刻发生的动作或某段时间内一直进行的动作。 如：1> At nine o’clock last night, I was counting the stars in the sky. 2> When the girl came in, the two dogs were fighting for a bone. 3> While I was preparing for the exam, the power was cut off. 8. 过去完成时：别名“过去的过去。”考题中对该时态的使用有要求，只有当句中有一个动作是过去时，才有可能用过去完成。 如：1> The film had almost finished when I got to the cinema. 2> By the time he was ten, he had built himself a chemistry lab. 9. 将来完成时：该时态只有一个考点，请大家注意与过去完成的区别： 如：By the time he is ten, he will have built himself a chemistry lab. 10. 现在完成进行时：表示现在以前一直发生的动作，强调动作在进行过程中的不间断，常有背景句作为铺垫。 如：—You are all wet! —Yes, I have been playing basketball all the morning. 语态：主要考察被动语态的用法。基本公式：主语 + be + 动词的过去分词。 还有一个要点大家需记住：只有及物动词才有被动语态。 除了大家熟悉的基本用法外，被动语态还有一些特殊用法，比如用主动的形式表达被动的概念，顾名思义，看起来是主动，实则为被动。 下面，我们将英文中常见的主动形式表被动含义的情况总结一下： 1> 动词read, sell, last, wash, write, lock等带状语,如well, easily时. e.g.① This kind of cloth washes easily.（这种布好洗） ② The meeting lasted three hours.（会议持续了三个小时） ③ My new pen writes well. （我的新钢笔好写） 2> 感官动词feel, look, smell, sound, taste, prove等与形容词连用时. e.g. ①You look very well today. ② Your bedroom smelt so terrible. ③ My words proved right. 3> begin, end, stop, open, close等表示开，关，结束的含义时，及break out, take place, happen等动词表示爆发，发生概念时。 e.g. ① The library opens at ten. ② Class begins at half past eight. ③ An earthquake took place in Tang Shan in 1976. 4> 某些做表语的形容词后，用不定式的主动形式。 e.g. ① The question is easy to answer. ② His clothes are hard to wash. ③ The fish is not fit to eat. ④ He has an important meeting to attend. 【典型例题】 1.

B。根据主语与build之间的被动关系和now，可知要选现在进行时的被动语态；因工厂正在修建，花费一年半应指将来。 5. C。shouldn’ t have done 表示“过去本不应……”。You did lose your temper 是You lost your temper 的强调形式。 6. D。现在完成进行时表示从过去某时到现在一直在进行的动作。 7. B。句意为：他们（现在）不愿买新衣服，因为他们在攒钱买电视。由此可见，攒钱是现阶段正在进行的动作。 8. C。担心是从过去某时到说话时为止一直在进行的动作，用现在完成时；expect 是在过去某一段时间里（整个晚上）正在进行的动作，故用过去进行时。 9. B。论文已完成，花费一个月时间应指过去；某事花费某人多少时间用sth.takes sb.some time 结构。 10. D。交通现在已经好了，在此基础上正在变得更好。 11. A。题干没有构成“过去的过去”，不可选B。如选C、D则表示动作已完成，与have no idea相矛盾。过去进行时表示过去某段时间或某一时刻正在进行的动作，不涉及结果，正好附合题干语境。 12. C。by then 是指将来的时间状语，排除A。再由句意可知，meet指的是到了十点钟时将正在进行的动作。 13. B。问句问的是前天回来之前去了哪儿，故用过去完成时。注意had gone表示人未回来，与第一句相矛盾。 14. D。for＋时间段表示从过去某时延续至今的动作或状态，用现在完成时；meet发生在got to know 这一过去动作之前，用过去完成时。 15. D。用一般现在时表示现在的特征或状态。 16. B。come, go, leave, arrive, take 等动词常用进行时表砂将来。 17. D。表示过去没有做某事应用去时。又因句子没有“过去正在进行”之意，帮排除A。 18. B。问对方“去了哪里”，指的是从过去某时到现在为止的动作，用现在完成时；第二个空格是与过去事实相反的虚拟语气和主句，条件状语从句If I hadn’ t got stuck in the heavy traffic 被省略。 19. C。在一个国际会议上被介绍显然发生在过去。 20. B。此句为复杂特殊疑问句结构，即“疑问词＋do you think （believe, suppose, expect, imagine, say, consider, guess等）＋其它（陈述语序）?”。 21. D。由but 分句中的现在时和答语所提建议内容，可知应选现在完成时的被动语态。 22. C。always, often, constantly, forever, all the time 等副词与现在（过去）进行时连用，表示某种反复发生的动作，往往带有厌恶、不满、责备或赞扬等意味。 23. B。这种电视产于上海是客观事实，故用一般现在时。 24. C。C项是was to have joined us in our discussion 的省略形式。was／were ＋ to have done表示原来计划、安排要做的事，而实际上并没有做。 25. B。当时他在听收音机。 26. D。表示按时刻表或日程安排要发生的事,应用一般现在时。 27. D。从句用的是一般现在时，故主句要用将来时。将来进行时表示在将来某一时刻或某段时间内正在进行的动作。 28. A。Look at this!说明东西已找到。紧接着说是怎样找到的。 29. C。根据答语，问句中的meet是过去发生的动作，可排除A、D。但不能选B，因为没有构成“过去的过去”。答语中用过去完成时的被动语态表示在我到达（过去动作）之前他已被人用车接走。 30. D。“没听”发生在对方（过去）问问题时，故用过去进行时。 【模拟试题】 31. I used to drink a lot of tea but these days I coffee.
