名詞性從句中連詞選擇“三步法”一下就會(huì)

1、名詞性從句中連詞選擇“三步法”在高考單項(xiàng)選擇中，名詞性從句中連詞的選擇往往是測(cè)試的熱點(diǎn)?？?生若不認(rèn)真分析，沒(méi)有一定的方法，常常造成判斷上的失誤，最終錯(cuò)選了 連詞。筆者認(rèn)為，如果考生能采取“一分二劃三看”三步法對(duì)試題加以分 析，則會(huì)收到良效。一、“一分”即分清從句類型：四種從句 主語(yǔ)從句（從句位于動(dòng)詞前作主語(yǔ)）賓語(yǔ)從句（從句位于動(dòng)詞后作賓語(yǔ)）表語(yǔ)從句（從句位于系動(dòng)詞之后作表語(yǔ)）同位語(yǔ)從句（從句位于特殊的名詞如idea,fact,news 等后補(bǔ)充說(shuō)明前面的名詞）二、“二劃”即劃分出從句（用括號(hào)表示從句）（1） （that the erath is round） is true.（主語(yǔ)從句）v（

2、2） do you know （where he lives ） ?（賓語(yǔ)從句）v、（3） my opinion is 3at you should not go alone）.（表語(yǔ)從句）v（4） i don't like the idea （that money is everything）.（同位語(yǔ)從句）n三、“三看”即看從句句意是否完整：1、句意不完整缺連接代詞人who,whoever （主語(yǔ)）whom,whomever（賓語(yǔ)）物what,whatever （主語(yǔ)、賓語(yǔ)） which,whichever （主語(yǔ)、賓語(yǔ)）2、句意完整(1)缺連接副詞：時(shí)間：when;地點(diǎn)：wher

3、e,wherever ;原因：why;方式：how。(2)缺不作成份的連詞 有含義：if 、wherther (是否)；無(wú)含義：that注：if 一般不用來(lái)引導(dǎo)主語(yǔ)從句；that只有在賓語(yǔ)從句中才可以省略。下面，我們以4道高考試題為例加以解析1、he said at the meeting astonished everybody present. (nmet 93,19)a、what b、that c 、the fact d 、the matter析：(1)分清從句類型：因?yàn)橹骶鋭?dòng)詞astonished前有一個(gè)從句，則一定 是主語(yǔ)從句。 戈世主語(yǔ)從句：( he said at the mee

4、ting ) astonishedeverybodyv present.(3)看主語(yǔ)從句句意是否完整：從句動(dòng)詞said后缺賓語(yǔ)，即句意不完整，則一定缺連接代詞。在四個(gè)選項(xiàng)中只有 what可以做said的 賓語(yǔ)，所以答案(a)正確。2、a computer can only do you have instructed it to do. (nmeti001, 31)a、how b、after c、what d 、when析：(1)分清從句類型：主句動(dòng)詞do后有一個(gè)從句，所以是賓語(yǔ)從句。(2)劃分出賓語(yǔ)從句： do_ ( you have instructedit to do.)v(3)看賓語(yǔ)從

5、句句意是否完整：不定式 to do后缺賓語(yǔ)，句意不完整， 應(yīng)缺少連接代詞，所以只有答案(c)正確。3、一 i drove to zhuhai for the air show last week.-is that you had a few days off?(nmet 99a、why b、when c、what d 、where析：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(yǔ)從句。(2)劃分出表語(yǔ)從句： 叵that(_you had a few days off ) ?v-(3)看表語(yǔ)從句句意是否完整：從譯文“你請(qǐng)了幾天假”可以判斷

6、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 beadmitted 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ainforma

7、tion "，所以是同位語(yǔ)從句。 戈岫同位語(yǔ)從句：information has been put forword ( more nmiddle school graduates will be admitted into universities).(3)看同位語(yǔ)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(gè)不作成份的連詞，故最佳答案為（b）。請(qǐng)同學(xué)們根據(jù)“三步法”，試作以下高考題：1、（ '96）we can 't get se
