(与现在事实相反)if i had been you then, i wouldnt have quarreled with him. (与过去事实相反)if i saw/ should see /were to see him tomorrow, i would be very happy. (与将来事实相反)二、错综时间条件句有时，条件从句的动作和主句的动作发生的时间不一致。例如: 一个是过去发生的，一个是现在发生的。这时主从句中的动词形式要根据所表示的时间作相应的调整。例如:1. if he had followed the doctors advice then, he would be quite all right now.2. tom would be alive today if the doctor had come sooner last night.三、(省if )倒装条件句如果条件句中有were, had（助动词）或should时，可使用倒装结构，但if必须省略。若条件从句为否定句，否定词not应置于主语之后，而不能与were，should，had等缩略成werent，shouldnt，hadnt置于句首。例如：1. had i seen him then, i would have been very happy.= if i had seen him then, i would have been very happy.2. should i have time, i would go with you. = if i should have time, i would go with you.3. were i not so busy, i would go with you. = if i were not so busy, i would go with you.四、含蓄条件句虚拟条件句中的条件从句有时不表现出来，只暗含在上下文中或用介词短语(without，but for) 或连词 (or, otherwise) 等来表示，这种句子叫做含蓄条件句。例如：bur for/ without your help, we wouldnt have succeeded. = if you had not helped usim really very busy, otherwise, i would certainly go there with you. = if i were not very busy四、典题训练 post-learning.consolidation一、单项选择1. thank you for all your hard work last week. i dont think we _ it without you. a. can manage b. could have managed c. could manage d. can have managed2. but for the help of my english teacher, i _ the first prize in the english writing competition. a. would not win b. would not have won c. would win d. would have won3. if the united states had built more homes for poor people in 1955，the housing problems now in some parts of this country _ so serious. a. wouldnt be b. will not have been c. wouldnt have been d. would have not been4. _ it rain tomorrow, we would have to put off the visit to the yangpu bridge. a. were b. should c. would d. will5. _ for the free tickets, i would not have gone to the films so often.a. if it is not b. were it not c. had it not been d. if they were not6the weather has been very hot and dry. yes. if it had rained even a drop, things would be much better now! and my vegetables . a. wouldnt die b. didnt die c. hadnt died d. wouldnt have died7. teachers recommend parents their children under 12 to ride bicycles to school for safety.a. not allow b. do not allow c. mustnt allow d. couldnt allow8. if he _my advice, he wouldnt have lost his job.a. followed b. should follow c. had followed d. would follow9. george is going to talk about the geography of his country, but id rather he_ more on its culture.a. focus b. focused c. would focus d. had focused10. if we _ the other road, we might have arrived here in time for the meeting. a. take b. had taken c. took d. have taken11. john went to the hospital alone.if he _ me about it, i would have gone with him.a. should tell b. tells c. told d. had told12. had i known about this computer program, a huge amount of time and energy _ . a. would have been saved b. had been saved c. will be saved d. was saved五、当堂检测task4. reading task (page 59)1. let the ss discuss the question: what do people usually do on april fools day?do you know any of the funny tricks people play on each other?2.ask the ss to read the passage abut the “noodle harvest” which is remembered as one of the best april fools jokes ever.3.have the ss read the passage again carefully and then fill in the chart.task4. read the passage again carefully and then fill in the chartna
