1、【英语】北师大版 典题精讲Unit 4 Cyberspace典题精讲经典例题例1Professor Smith,along with his assistants, _on the project day and night to meet the deadline.A.work B.workingC.is working D.are working思路解析：along with连接两个名词作主语,动词要和前面的名词一致。此题的主语是Professor Smith,是单数,因此动词必须用第三人称单数形式。答案:C黑色陷阱：如果误把此题的主语看成是Professor Smith和his assi

2、stants,就可能错选A 或者是D项。如果误以为along是动词,就可能错选B项。绿色通道：做此类题目主要是要记住一些连词在连接两个名词作主语时的用法,这样的连词还有except,but,as well as,with 等。例2全国What would you do if it_tomorrow?We have to carry it on,since weve got everything ready.A.rainB.rainsC.will rainD.is raining思路解析：if引导的条件状语从句中用一般时代替将来时。答案:B黑色陷阱：如果不知道if条件句中时态的用法此题就会选错C

3、项。如果没注意到it是单数,那么会错选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：此题易把Mr.White_at 8:30 for the m

4、eeting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拟熟悉。例5(经典回放It was necessary that he_h

5、ere every Sunday.A.cameB eC esD.must come 思路解析：此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“should+动词原形表示虚拟语气。原创题例1Can I speak t

6、o Mr.Li,please?_A.Who are you?B.Im Li.C.Speaking.D.Are you Tom?思路解析：此题是 用语,打 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,要求对交际用语比拟了解,尤其是和母语的说话方式不同的地方。例2I think Mother would like to know_Ive been up to so far,so I decide to send h

7、im 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 like some more bread?_.Ive had enough.A.Yes,ple

8、aseB.No,thank youC.NothingD.The more,the better思路解析：此题考查交际用语。对于“Would you like.?的答复,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：此题有两处陷阱：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.?句式的肯定答复和否认答复,即:肯定答复为:Yes,please.,否认答复为: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
