1、 名詞性從句一直備受高考命題者的關(guān)注，近幾年來的高考題主要考查在具體語境中連接詞的選擇，尤其是連接詞what和that的辨析，以及whether 與if表示“是否”時(shí)的區(qū)別。因此，正確區(qū)分名詞性從句的類型，根據(jù)在從句中的作用和所表達(dá)的意義，確定恰當(dāng)?shù)倪B接詞是一輪復(fù)習(xí)的重點(diǎn)。此外，名詞性從句和定語從句的辨析，也是高考考查的重點(diǎn)。 一、認(rèn)識(shí)各種名詞性從句名詞性從句相當(dāng)于名詞，可分別作句子的主語、表語、賓語和同位語。因此，名詞性從句具體分為主語從句、表語從句、賓語從句和同位語從句。名詞性從句中的連接詞有連詞that / whether / if，連接代詞what / who(m)/ which /

2、whose / whatever / whoever / whomever / whichever，連接副詞where / when / why / how 。從名詞性從句在句中所起的作用來說，名詞性從句是句子不可缺少的一部分，和句子的其他成分之間也不會(huì)用逗號(hào)隔開。而定語從句和狀語從句是句子中的修飾成分，去掉之后不會(huì)影響句子主體結(jié)構(gòu)的完整性。這是判斷是否是名詞性從句最主要的特征。如：I wonder how much these shoes cost. (賓語從句，不可省去)He is the very man I look after. (定語從句，修飾the man)You may bor

3、row the book as long as you keep it clean. (狀語從句)1主語從句Who will go is not important. It doesnt matter so much whether you will come or not.

4、an get more people to help in the work. That is why the brothers wanted to make a bet. It looked as if it was going to rain. 3 .賓語從句I hope (that) everything is all right. 注意：(1)that在引導(dǎo)賓語從句時(shí)，常可省略，但如果有兩個(gè)以上的賓語從句時(shí)，最后一個(gè)從句的that不能省略。如：I know (that) he has just graduated from college and that he is looking

5、for a job. (2)如果動(dòng)詞賓語后又有補(bǔ)語，那么要使用it作形式賓語，然后把賓語從句放在補(bǔ)語之后。如：I make it known that well be invited to the ball. (3)如果主句的謂語動(dòng)詞的時(shí)態(tài)是一般過去時(shí)，那么從句的時(shí)態(tài)要采用相應(yīng)的與過去有關(guān)的時(shí)態(tài)，但如果從句描述的是客觀事實(shí)，從句時(shí)態(tài)不可調(diào)整“呼應(yīng)”。如：She remembered that she had left her wallet at the school gate. Our teacher said that light travels faster than sound. 4同位

6、語從句同位語從句在句中作某一名詞的同位語，一般位于該名詞(如：news, fact, idea, suggestion, promise等)之后，說明該名詞的具體內(nèi)容。如：I have no idea when he will be back.The fact that he had not said anything surprised everybody. 注意：在動(dòng)詞：一堅(jiān)持(insist)、二命令(order，command)、三建議(suggest，advise，recommend)、四要求(demand，require，request，ask)后的賓語從句和這些動(dòng)詞的過去分詞后的主

7、語從句，以及這些動(dòng)詞的名詞引出的表語從句和同位語從句中，謂語部分常用(should)do形式。如：He insisted that he (should) try once again. His advice is that everyone (should) do his best to help the poor girl.
