Is that you had a few days off?（NMET 99）A、why B、when C、what D、where 析：（1）分清從句類型：從句“ you had a few days off”位于“is”之后，所以應(yīng)該是表語從句。 （2）劃分出表語從句：Is that（ you had a few days off）? v （3）看表語從句句意是否完整：從譯文“你請了幾天假”可以判斷句意完整，應(yīng)該缺連接副詞或不作成份的連詞。根據(jù)上下文含義，應(yīng)該選擇表示“原因”的“why”，所以最佳答案為（A）。4、Information has been put forword more middle school graduates will be admitted into universities.（2001年上海試題）A、while B、that C、when D、as析： （1）分清從句類型：根據(jù)句子結(jié)構(gòu)分析“more middle school graduates will be admitted into universities.”應(yīng)該修飾名詞“Information”，所以是同位語從句。（2）劃出同位語從句：Information has been put forword（ more nmiddle school graduates will be admitted into universities).（3）看同位語從句句意是否完整：根據(jù)從句含義“更多的中學(xué)生將被大學(xué)錄取”可以判斷，從句句意完整，所以可能缺連接副詞或不作成份的連詞。（A）、（D）答案不是名詞從句中的連詞，根據(jù)句子的含義，應(yīng)選一個不作成份的連詞，故最佳答案為（B）。請同學(xué)們根據(jù)“三步法”，試作以下高考題：1、（96） we cant get seems better than we have.A、What;what B、What;that C、That;that D、That;what2、（96） well go camping tomorrow depends on the weather.A、If B、Whether C、That D、Where3、（97）It is generally considered unwise to gaive a child he or she wants.A、however B、whatever C、whichever D、whenever 4、（98）Why do you want a new job youve got such a good one already?A、that B、where C、which D、when 5、（98） caused the accident is still a complete mystery.A、What B、That C、How D、Where6、（99） has helped to save the drowning girl is worth praising.A、Who B、The one C、Anyone D、Whoever7、（00） she couldnt understand was fewer and fewer students showed interest in her lessons.A、What;why B、That;what C、What;because D、Why;that8、（01）What the doctors really doubt is my mother will recover from the serious disease soon.A、when B、how C、whether D、why9、（03）There is a new problem involved in the popularity of private cars road conditions need .
