四六級(jí)語(yǔ)法練習(xí)題（含答案）：名詞性從句

1. ___ is a fact that English is being accepted as an international language. (NMET 1995)

A. There B. This C. That D. It

答案D。當(dāng)名詞從句在句中作主語(yǔ)時(shí)，為避免句子頭重腳輕，常用it作形式主語(yǔ)置于句首，而將真正的主語(yǔ)從句放在句尾。此時(shí)it只起先行引導(dǎo)作用，本身無(wú)實(shí)義。此句也可以改寫為：That English is being accepted as an international language is a fact.

2．A computer can only do ____ you have instructed it to do．（NMET2001）

A．how B．a(chǎn)fter C．what D．when

答案C。從句子結(jié)構(gòu)可知，句子的空白處應(yīng)該填引導(dǎo)賓語(yǔ)從句的連詞，做主句謂語(yǔ)動(dòng)詞do的賓語(yǔ)，同時(shí)該連接詞還是從句中的do的賓語(yǔ)，因此，此處的連接詞應(yīng)該用what。

3. He asked ____ for a violin．（MET1992）

A. did I pay how much B. I paid how much

C. how much did I pay D. how much I paid

答案：D。賓語(yǔ)從句相當(dāng)于特殊疑問(wèn)句，句子語(yǔ)序要用陳述語(yǔ)序。

4. What the doctors really doubt is ____ my mother will recover from the serious disease soon．（上海2001年春季招生）

A. when B. how C. whether D. why

答案C。這是一個(gè)表語(yǔ)從句。根據(jù) doubt一詞可知，所懷疑的應(yīng)是是否能治好病，所以要填whether。這句話的意思是“醫(yī)生真的懷疑我媽媽是否能很快從重病中恢復(fù)過(guò)來(lái)?！?/p>

5．It is generally considered unwise to give a child _____he or she wants. (NMET1997)

A. however B. whatever C. whichever D. whenever

答案B。根據(jù)句意“一般認(rèn)為孩子要什么就給什么是不好的?！笨梢钥闯龊竺娴膹木鋺?yīng)是一個(gè)賓語(yǔ)從句，而從句中wants缺少賓語(yǔ)，A. however 和D. whenever是不能作賓語(yǔ)的；排除A和D，whichever表示“無(wú)論哪一個(gè)，無(wú)論哪些”，應(yīng)表示一定范圍內(nèi)的人或物，此處沒(méi)有涉及事物的范圍，所以應(yīng)選 B．whatever，表示“無(wú)論什么”。

6. ______leaves the room last ought to turn off the lights. (MET1988)

A. Anyone B. The person C. Whoever D. Who

答案C。本題句子的意思是：無(wú)論誰(shuí)最后離開(kāi)房間一定要把燈關(guān)掉。本題考查連接代詞whoever引導(dǎo)的名詞性從句，連接代詞whoever可以引導(dǎo)名詞性從句，并在從句中作主語(yǔ)，相當(dāng)于any person who或The person who, 意為“一切……的人”。而anyone和the person均非連詞，不能引導(dǎo)從句，況who leaves the room last意為“某個(gè)最后離開(kāi)房間的人”，與題意不符，如果要選A. Anyone或B. The person，都必須在它們后面再加上引導(dǎo)定語(yǔ)從句的關(guān)系代詞who。如果要選D. Who就體現(xiàn)不出“無(wú)論誰(shuí)”的含義了。

7. Sarah hopes to become a friend of ______shares her interests. (Shanghai1995)

A. anyone B. whomever C. whoever D. no matter who

答案為C。本題句子的意思是：Sarah希望跟自己有共同愛(ài)好的人交朋友。疑問(wèn)詞+ever引導(dǎo)的名詞性從句與no matter+疑問(wèn)詞引導(dǎo)的從句的區(qū)別是：前者既可以引導(dǎo)名詞性從句也可以引導(dǎo)讓步狀語(yǔ)從句；后者只能引導(dǎo)讓步狀語(yǔ)從句。首先排除A和D，從句中需要的是主語(yǔ)，所以whomever也不行。

8. ---- I drove to Zhuhai for the air show last week.

---- Is that ______ you had a few days off ? ( NMET1999)

A. why B. what C. when D. where

答案A。根據(jù)語(yǔ)境，甲說(shuō)上周驅(qū)車去珠海觀看航模展覽。乙據(jù)此來(lái)詢問(wèn)甲這是否是請(qǐng)幾天假的原因，故答案是A。答案B,C, D均與該題語(yǔ)境不符。根據(jù)上句提供的語(yǔ)境，下句應(yīng)該問(wèn)“那就是你為什么離開(kāi)幾天的原因嗎？”

9. I still remember ______ this used to be a quiet village. ( NMET1993)

A. when B. how C. where D. what

答案A。根據(jù)從句中缺少的句子成分是狀語(yǔ)，排除D．what，而答案C, D均與題意不符，所以應(yīng)選A．when。used to be表示一種過(guò)去存在的狀態(tài)，本句的意思是“我仍然記得這里在什么時(shí)候是個(gè)寧?kù)o的地方?！?/p>

10．I read about it in some book or other，does it matter ____ it was ?（2001春季招生）

A．where B．what C．how D．which

答案D。這是一個(gè)主語(yǔ)從句。主語(yǔ)從句中缺少表語(yǔ)。從上句的意思分析，應(yīng)是哪本書(shū)，所以要填which，這句話的意思是“我在某本書(shū)中讀到過(guò)有關(guān)這方面的內(nèi)容，是哪一本書(shū)重要嗎？”。

11. Information has been put forward ____ more middle school graduates will be admitted into universities.

A. while B. that C. when D. as (2001年上海)

答案B。該題考查that引導(dǎo)的同位語(yǔ)從句。同位語(yǔ)從句通常由that引導(dǎo)，接在fact, news, promise, possibility, information, doubt, message名詞后，用來(lái)解釋或說(shuō)明名詞的內(nèi)容。

12. —I think it is going to be a big problem.

—Yes, it could be.

—I wonder ______ we can do about it. (北京 2002春季)

A. if B. how C. what D. that

答案C。本題考察名詞性從句的連接詞的用法。wonder后面應(yīng)跟賓語(yǔ)從句，而從句中的謂語(yǔ)動(dòng)詞do是及物動(dòng)詞，可見(jiàn)從句缺少一個(gè)代替賓語(yǔ)的成分，我們可以用排除法排除不作成分的if和that，再排除引導(dǎo)方式狀語(yǔ)的how，答案是C，句子的意思是“我們能就此做些什么”。
