()3)下列句型中常用现在完成时This/That/It is the first /secondtime that +完成时This/That/It is the only +that+完成时This/That/It is the best/finest/most interesting+that从句+完成时一般过去时与现在完成时的区别1.凡有过去时间的均用过去时态，不能用完成时态，如含有ago, last year, just now, the other day等，现在完成时通常与表示包括现在在内的时间状语连用2.现在完成时强调过去某事对现在造成的影响，主要是说明现在的情况，一般过去时只表示过去发生的事情本身，不涉及与现在的关系。六. 过去进行时were/was+doing1.表过去某一时刻或某一段时间正在进行的动作，这一特定时间往往须用时间状语表示e.g. What was your sister doing this time yesterday?She was reading a book when I come in.注：1）go, come, leave等的进行时，可表过去即将发生的动作 2）某些动词不能用进行时（见现在进行时）2.用于描述一件事发生的背景，一个长动作延续的时候，另一个短动作发生七.过去完成时“过去的过去”had+done 1. 在by, by the end, by the time, until, before, since后接表示过去某一时间的短语或从句以前发生的动作。e.g. By the end of last year, we had produced 20,000 cars, The train had left before we reached the station.2.表示未曾实现的希望，打算，意图，诺言等，常用had hoped /planned /meant /intended /thought /wanted/ expected 等e.g.His wife had hoped to catch the first train but she was too late.3.“时间名词+before”在句子中作状语，谓语动词用过去完成时；“时间名词+ago”在句子作状语，谓语动词用一般过去式。e.g. He said his first teacher had died at least 10 years before. Xiao Hua left school 3 years ago.4.表示“一就”的几个句型：Hardly/Scarcelywhen 主句用过去完成时 No sooner than 从句用一般过去时e.g. We had no sooner been seated than the bus started. =No sooner had we been seated than the bus started.注：当一个由before, after, as soon as等连词引导的从句所表示的动作和主句的动作紧接发生时，由于这些连词本身已说明两个动作的先后关系，因此两个动作均可用“一般过去时”e.g. The train started to move just before he reached the station.After he (had) left the room, the boss came in.We arrived home before it snowed.八.过去将来时 should/would+ do1.从过去某时看将要发生的动作e.g. They didnt expect that I would say so.2过去习惯的动作e.g. Every night he would study late.3.表“愿望”，“倾向性”e.g. It was raining hard but none of us would stop working.4.was/ were +going to do was/ were +going/coming/leaving was/ were +to do was/ were about + to do 九.现在完成进行时have/has been doing 从过去某一时刻开始一直延续到现在并可能将延续下去的动作。e.g. Tom has been watching TV since this morning.十.过去完成进行时 had been doinge.g. Nobody knew what Peter had doing these years.十一.将来进行时1. 表示将来某时进行的状态或动作，或按预测将来会发生的事情e.g. Shell be coming soon. 她会很快来的。Ill be meeting him sometime in the future.以后找时间我一定去会会他。注：将来进行时不用于表示“意志”，不能说Ill be having a talk with her. 2. 常用的时间状语有soon, tomorrow, this evening, on Sunday, by this time, tomorrow, in two days, tomorrow evening等e.g. By the time next year, Ill be lying on the beach. 明年这个时候，我正躺在沙滩上呢！时态呼应某些从句（主要是宾语从句）中谓语动作的时态常常受主句中谓语动词的影响，这叫做时态的呼应，也叫时态的一致。1主句中谓语动词为现在或将来时态时，从句中的谓语动词可以用任何所需要的时态。e.g. She says she is (was, will be)a teacher.Can you tell me when you left (are to leave)for Tibet?2.主句中谓语动词为过去时态时，从句的谓语动词的时态为一般过去时 从句谓语与主句谓语所表示的过去进行时 动作同时发生过去完成时 从句动作先于主句动作发生过去将来时 从句动作在主句动作之后发生 e.g. He told me he was ill. She said she was writing an article. He told me that she had caught up with the others. He said he would be a doctor when he left school.但：1）从句所说明的如果是普遍真理，则仍用现在时态e.g. The teacher told the children that the earth goes round the sun.2)从句有一表示具体时间的状语，其谓语动作先于主句发生，也不用完成时，而用一般现在时e.g. He said he was born in 1970. The teacher told the pupils the Peoples Republic of China was founded in 1949.另：主语从句，表语从句，同位语从句一般也要遵守时态呼应规则，而定语，状语从句一般不受主句谓语动词的影响，而是根据需要选用适当的时态。e.g. It seemed to me that I had met him before.(主语从句)That is what he wants.(表语从句)The fact that he studied hard was known to us all.(同位语从句)I found a very interesting book about physics, which I shall give you as soon as you come.(定语从句)She took part in the rebuilding of the machine as she wants to improve it. (状语从句)动词的语态主动，被动被动语态的构成方式：1.be +过去分词，口语中也有用 get/ become+过去分词表示2.情态动词+ be + 过去分词被动语态的基本用法：不知道或没必要提到的动作执行者是谁时，用被动语态，强调或突出动作的承受者常用被动语态（by短语有时可以省略）一. 使用被动语态时应注意的几个问题1. 主动变被动时双宾语的变化。e.g. My friend gave me an interesting book on my birthday.An interesting book was given to me(by my friend) on my birthday.I was given an interesting book (by my friend) on my birthday.2. 主动变被动时，宾补成主补（位置不变）：（作补语的）不定式前需加to.e.g. The boss made him work all day long.He was made to work all day long (by the boss).3. 短语动词变被动语态时，勿要掉“尾巴”.e.g. The children were taken good care of (by her). Your pronunciation and spelling should be paid attention to.4. 情态动词和be going to, be to, be sure to, used to, have to, had better等结构变被动语态，只需将它们后面的动词原形变为be+ 过去分词。e.g. He is sure to finish the article in an hour.=The article is sure to be finished in an hour.二. 不能用被动语态的几种情况1. 所有的不及物动词或不及物动词词组不能用于被动语态之中。2. 表示状态的谓语动词，如：last, hold, benefit, contain, equal, fit, join, mean, look like, consist of 等3. 表示归属的动词，如：have, own, belong to等4. 表示“希望，意图”的动词，如：wish, want, hope, like, love, hate等5. 宾语是反身代词或相互代词时谓语动词用主动语态，不能用被动语态6. 有些动词以其主动形式表示被动意义，特别是当主语是物时，常见的动词有sell, write, wash, open, lock 等三. 主动形式表被动意义1. 当feel, look, smell, taste, sound等后接形容词时，当cut, read, sell, wear, write, wash等带状语修饰语时，当动词表示“开始，结束，关，停，转，启动”等意义时e.g. This kind of cloth washes easily.These novels wont sell well.My pen writes smoothly.The door wont lock.The fish smells good.2. 当break out, take place, shut off, turn off, work out等动词表示“发生，关闭，制定”等意思时。 e.g. The plan worked out successfully.The lamps on the wall turn off.3. want, require, need后面的动名词用主动表示被动含义e.g. My watch wants repairing.4. be worth doing用主动形式表示被动含义5. 在“be+形容词+to do”中，不定式的逻辑宾语是句子的主语，用主动代被动e.g. This kind of water isnt fit to drink.The girl isnt easy to get along with. 四. 被动形式表主动意义的几种情况1. be seated 坐着e.g. He is seated on a bench. 他在凳子上坐下。 He seats himself on a bench.2. be hidden 隐藏e.g. He was hidden behind the door. 他躲在门后。 He hid himself behind the door.3. be lost 迷路，迷失于4. be drunk 喝醉5. be dressed 穿着e.g. The girl was dressed in a red short skirt.五. 被动语态与系表结构的区别被动语态强调动作，系表结构表主语的特点或状态e.g. The book was sold by a certain bookstore.（被动） The book is well sold. （系表结构）
