常考知识点条件、时间、让步状语从句中的“主将从现”；一般过去时、现在完成时和过去完成时的区别；将来完成时。一、一般现在时： 1、表示经常发生或是反复发生的动作或存在的状态： 常和always, usually, often ,sometimes, every day, every week等时间状语连用。 She visits her parents every day. 2、表示普遍的、永恒的真理。由于是众所周知的客观事实，所以一般不用时间状语。 The moon goes round the earth. Summer follows spring. 3、一般现在时常可表示按规定、时间表、计划或安排要发生的事情，通常都有一个表示未来时间的状语。 The show begins at seven and ends at ten. 4、在少数情况下，已发生的动作也可以用一般现在时来表示，但只限于少量动词，如hear, say, tell等。 I hear you’re moving. They tell me it’s a fascinating film. 5、在时间、条件从句中用一般现在时表示将来的动作，遵循“主将从现”的原则。常用连词有as soon as, when, until, if, unless.（1）"When are you going to visit your uncle in Chicago?" wb.yGfJ
"As soon as ______ our work for tomorrow." h vYRAQR:
A. we're complete B. we'd complete C. we‘ll complete D. we complete
"'z}oS

A. have finished B. finish C. finished D. was finishing（3）When the mixture ______, it will give off a powerful force. e(8hSVcl4
A. will heat B. will be heated C. is heated D. has heated 二、现在进行时1、表示此时此刻（说话时）正在进行的动作。在译成汉语时有时带有“（正）在”这类字样。 sv=U^xI
They’re talking; they’re not working. We’re having a meeting. 2、表示现在这个阶段正在进行的动作。（但说话的一刻不一定在进行） Lm 4`O %
We’re seeing the sights of the city. （说话时不一定在观光）3、现在进行时还可以用来表示按计划或安排要进行的动作，这时都有一个表示未来时间的状语： Mike is coming home on Thursday. They are having a party next week. 三、现在完成时现在完成时是一个把过去和现在联系起来的时态。谈得都是已经发生的事情，但和现在有某种关系，就是指从过去某时到现在，某事已经完成或是已经发生。1、表示动作刚刚发生（常和just, now, already, yet等词连用）；或表示动作的结果（一般不用时间状语）。 unFRf ec{
I have just had my lunch. I’ve already posted your letters. 2、表示过去某时开始的动作一直延续到现在，并且可能会继续延续下去（常用since引导的短语或从句，或由for 引导的短语连用）。She has been a dancer for ten years. 她已经当了十年的舞蹈演员了。（还有可能继续当下去）。 bh.&vp.kP
（1）He has _____ the army for ten years and is now an officer. ]:gW+6w"C
A. gone into B. joined in C. been in D. come into 3、 在since引起的从句中通常用一般一般过去时，而主句中的动词一般都用现在完成时。英语中有些动词不能延续（如meet, leave, arrive等），因此不能和表示延续的时间状语连用(如for ten years)： I have had a baby since I saw you last. 当主句表示“有多少时间”时，动词可用一般现在时： It is ten years since he left home and joined the army. 4、have （has）gone to和have（has）been to的差别：have（has ）been to：表示到过某个地方（表示某人的一种经历），人并不在那里， 可以和once，twice，often，never，ever 连have（has）gone to： 表示“到某地了”（表示某人已经离开此地，在去某地的路途上或已在某地），此句型不能与上述时间状语连用。 （1）He has gone to China. （2）He has been to China twice. 四、现在完成进行时表示从过去某时一直延续到现在的一个动作，这个动作一般会继续延续下去，或是到说话时结束， 但是强调到说话时为止一直在做的动作。 The ground is wet. It has been raining. 地是湿的。刚下雨来着。1、现在完成时常常有一个表示现在之前这一段时间的状语： I have been learning English for three years. 2、有时表示在持续的一段时间内动作的多次重复（而动作不一定在持续） Jim has been phoning Jenny every night for the past week. I _____ on the door for ten minutes now without an answer. /2?
CB\
A. was knocking B. am knocking C. knocking D. have been knocking 五、一般过去时：1、表示过去发生的动作或存在的状态：常和具体的过去时间状语连用，如just now, last week, when she was 18 years old等。即使在前一分钟发生的事情也要用过去时。 （1）I saw your sister a few days ago. （2）I met her a minute ago. 2、used to do sth：过去常常做…… I used to have a cup of milk in the morning. 3、it is high time（that），it is time (that)…句型中，谓语动词用过去时。 It is high time they arrived. （1）Let's finish our homework in a few seconds; it's time we __________. b{<? E };%
A. played football B. will play football C. play football D. are playing football （2） Don’t you think it is time you _____ smoking? B.; qvuM~
A. give up B. gave up C. would give up D. should give up （3）It’s high time we _____ something to stop traffic accident. T<B}Z11R
A. do B. will do C. did D. must do（4）You’ve already missed too many classes this term .You _____ two classes just last week. +Hu\b
& g
A. missed B. would miss C. had missed D. have missed六、过去进行时1、表示在过去某个时间正在进行的动作。相当于现在进行时的过去形式。常需用表示过去的时间状语或通过上下文来判断时间。 During the summer of 1999， she was traveling in China. 2、when 和while 的用法区别 2f[; U"
when 表示一个特定时间点，其所引导的句子用过去时，while 表示持续的一段时间，其所引导的句子用过去进行时。 （1）Edison was not a good student when he was a young boy. （2）While he was eating, I asked him to lend me $2. 3、过去进行时表示过去将来的动作。现在进行时可以表示将来的动作，同样，过去进行时也可以表示从过去某时间看将来要发生的动作。 He went to see Xiao Li. He was leaving early the next morning. kkjugm{D7
4、was going to表示“准备做某事”或“将要发生某事” She was going to buy him some shoes. （1）I fell and hurt myself while I _____tennis. >%t G[jb
A. was playing B. am playing C. play D. played（2）When you _____ this over with her, you should not see her any more. VM%g QOo<
A. talk B. talked C. will talk D. talking 七、过去完成时1、表示在过去某时之前已经完成了的动作（即过去的过去）。这个过去的某一时间可用by, before等介词或连词引导的短语或一个从句来表示。 （1）We had scarcely reached the school before it began to rain.我们刚到学校天就下雨了。 （2）By this time he had already made some friends. 2、表示从过去某一时间开始，一直持续到另一个过去的时间的动作。 When I got to the station the train had left. 3、在含有before, after, as soon as 等连词引导的状语从句的复合句中，由于连词本身可以明确表示动作发生的先后顺序，因此，主句和从句都可以用一般过去时表示，而不用过去完成时。 *S}@DoXS
I called him as soon as I arrived. 。4、过去完成时常用在 no sooner …than…, hardly/scarcely/barely…when…，一……就……。句型之中，句子倒装。（1）Hardly had I opened the door when he told me. 我刚开开门，他就告诉了我。（2）Scarcely had he opened the door when a gust of wind blew the candle out. &[[r|

A. had been on B. was on C. has been on D. would be on（4）No sooner had we sat down _____ we found it was time to go. w^0hVrws=,
A. than B. when C. as D. while八、一般将来时1、一般将来时表示将要发生的事情或是动作，在各种人称后都由will加动词原形构成，第一人称后可以用shall，常缩略为“’ll”： s`$}xukT
They say that it will rain. 2、be going to +动词原形：表示看来就要发生的事情或打算要做的事。 >`AK'K8{M

（2）George W. Bush is arriving in Shanghai tonight. 九、将来完成时将来完成时是这两年常考的语法点，基本结构是“will/shall + have done”，表示在将来某一时刻之前完成的动作。 I’ll have finished my work by five this afternoon. The snow will have disappeared before the end of March.(1) By next year he ______ in New York for five years. G!Brt&_'

2） 在条件句中的应用 xq((]5P
y
条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。 un 5r9

A. would come B. would have come C. had come D. came （答案：C）（1995年59题）二、if引导的虚拟条件句条件句指表示假定情况的句子，大都包含一个由if引导的条件从句。条件句有两种，一种表示可能成为现实的情况，即为真实条件句。 If you ask him, he will help you. 完全是假想，与现实不一样的或发生的可能性不大，就要用虚拟条件句。 If I were you , I’d go to night school. If she were younger, she would study computer science※如谓语包含were , had, should等词，这时候要用倒装语序， 即把这些词放到主语前面，省略if。 Were she in charge(=If she were in charge), she would do things differently. 如果是她负责，她会是另一种做法。 Should I be free tomorrow, I would come. 万一明天我有空我会来。（1）__________ the advice of his friends, he would not have suffered such a heavy loss in his business. : 6Nb,Hh~

A. If I realized B. Had I realized C. Did I have realized that D. As I realized三、含蓄虚拟条件句 在不少情况下，句子不一定包含一个条件从句，但意思却和条件句差不多，这时谓语仍可以用虚拟语气，这样的句子叫含蓄虚拟条件句。常用with，without，but for。 But for my brother's help, I would not have finished. Without your help, I couldn’t have achieved all this.（1）Without heat and sunlight, plants on the earth ______ well. 1O`V_d)

A. should have B. would have had C. would have D. will have had 四、以wish（that）引导的表示“愿望”的宾语从句这种从句有两类：一类表示现在或将来的愿望：基本形式是“主语＋wish ＋从句（主语＋过去时）”。 I wish we had a car. 要是我们有一辆车多好啊。 I wish I were 30 years younger. 我但愿自己能年轻三十岁。第二类表示一个过去没有实现的愿望：其形式是“主语＋wish +从句（主语＋过去完成时）”。这种情况表达的意思往往不能挽回，常常有懊悔的意思。 I wish that I had never met him. 但愿我从来没有见过他。 I wish you had let me know earlier. 你早些让我知道就好了。（1）I didn’t go to the party, but I do wish I _____ there. :XhF:c[.:

A. could study B. studied C. had studied D. would study五、would rather＋句子（过去时）在would rather后的宾语中，谓语常常用相当于过去式的形式表示现在或将来的情况，也可以用相当于过去完成时的形式表示过去的情况。来表示宁愿、宁可的意愿，语气比较婉转。 I would rather they left on an early train. 我更愿意他们坐早一点的火车走。（表现在） I’d rather he hadn’t told me about it. 我宁愿他没告诉我这事。（表过去）（1）I am too busy these days. I would rather all of you _____ next month for a dinner. n}UJ - \$
A. come B. would come C. came D. have come（2）I’d _____ you didn’t touch that, if you don’t mind. AAQ!8!
