3、：如果不知道if条件句中时态的用法本题就会选错C项。如果没注意到it是单数,则会错选A项，或忽略了tomorrow,就可能错选D项。例3(典题回放)Mr.White_at 8:30 for the meeting but he didnt show up.A.should have arrivedB.should arriveC.should have hadD.should be arriving思路解析：从but he didnt show up中可知,Mr.White 没有到会,且时态是过去,因此Mr.White 到会是表示与过去事实相反的事,是一种虚拟。答案:A黑色陷阱：本题易把Mr.
4、White_at 8:30 for the meeting与条件句相混淆错选C项,或没有分清时态错选B项。例4(经典回放）How long are you staying?I dont know. _.A.Thats OKB.Never mindC.It dependsD.It doesnt matter思路解析：How long are you staying?提示“将待多久”,I dont know.提示“不知道,要看情况”。答案:C黑色陷阱：如果不知道“It depends.”的意思,这题就不容易选对。绿色通道：这种对话题关键还是要看具体的情景,也要对一些常用的用语比较熟悉。例5(经典回
5、放）It was necessary that he_here every Sunday.A.cameB.comeC.comesD.must come 思路解析：本题考查主语从句中虚拟语气的用法,从句中的谓语动词是should+动词原形,should可以省去。答案：B黑色陷阱：由于不知道主语从句中用虚拟语气,受it was 或every Sunday 的干扰而错选A或C项。绿色通道：在某些“It is+形容词+that.”句型中，如“It is necessary (important,strange,natural,pity) that.”，that所引导的主语从句中谓语动词均用动词原形或“
6、should+动词原形”表示虚拟语气。原创题例1Can I speak to Mr.Li,please?_A.Who are you?B.Im Li.C.Speaking.D.Are you Tom?思路解析：本题是电话用语,打电话时要用“Who is that?”代替“Who are you?”,用“Is that Tom?”代替“Are you Tom?”,用“This is Li.”代替“Im Li”所以排除A、B、C三项。答案:C绿色通道：这类题目是交际用语题,要求对交际用语比较了解,尤其是和母语的说话方式不同的地方。例2I think Mother would like to kno
7、w_Ive been up to so far,so I decide to send him a quick note.A.whichB.whyC.whatD.how思路解析：be up to 意为“做,从事”,这里的to是介词后面跟名词,本句中to 后面没有名词,因此提问的时候要用what。答案:C黑色陷阱：如果不知道be up to 的意思,将to so far连在一起理解成为直到现在,那么这题就会错选B、D项。绿色通道：做这类题目要牢记固定词组的意思,还要搞清楚哪些词组中的to是介词,如：look forward to,listen to中的to 也都是介词。例3Would you l
8、ike some more bread?_.Ive had enough.A.Yes,pleaseB.No,thank youC.NothingD.The more,the better思路解析：本题考查交际用语。对于“Would you like.?”的回答,如果表示愿意,可以说“Yes,please”,但如果不愿意,通常用“No,thank you”。答案:B黑色陷阱：本题有两处陷阱：一是忽略后边的补充信息“Ive had enough.”,误选A或D项；二是没有真正理解上面的提问,误选C项。绿色通道：要做好此类题,需要熟记Would you like.?句式的肯定回答和否定回答,即:肯定回答为:Yes,please.,否定回答为:No,thanks/thank you.巧学法园地锁定whether的用法主语从句用whether,宾语从句or not,不定式前介词后,取代if别条件。（不能取代引导条件句的if）高考资源网版权所有，侵权必究！
