急求30道高一名詞性從句的題目,要有答案和答案解釋~~~.
要有解釋,一定要有解釋,解釋越詳細越好.

解答：

1.____ we can’t get seems better than ____ we have.
A. What; what B. what; that C. That; that D. That; what
解析：本句包含一個主語從句和一個賓語從句,且兩個從句都缺乏賓語,可見兩個引導詞都必須充當成分,所以答案是A.引導主、賓、表語從句時,what要充當主語、賓語或表語等句子成分,that不作任何成
分,只在語法上起連接的作用
2____ caused the accident is still a complete mystery.
A. What B. That C. How D. Where
解析：該題答案是A,what在主語從句中作主語,即作謂語動詞caused的執行者.在下面的例句中,that不充當任何成份,只起語法連接作用（因爲句子本身不缺成分）：That the former Iraq president Saddam was captured has been proved
3____ the 2000 Olympic Games will be held in Beijing is not known yet.
A. Whenever B. If C. Whether D. That
解析：試題中的從句位於句首,不難知道這是一個主語從句,所以答案是C.但是當賓語或主語從句爲否定句時,只能用if引導,不能用whether引導.
4____ you don’t like him is none of my business.
A. What B. Who C. That D. Whether
答案是C,that不充當句子成分,只起連接作用.由於該主語從句是否定句,所以不能用whether引導.
5.No one can be sure ____ in a million years.
A. what man will look like B. what will man look like
C. man will look like what D. what look will man like
解析：由於從句不能倒裝,所以答案只能是A與別的從句一樣,名詞性從句必須用自然語序,即使在疑問句中,從句也不倒裝（而在主句上倒裝）.
6.You can’t imagine ____ when they received these nice Christmas presents.
A. how they were excited B. how excited they were
C. how excited were they D. they were how excited
解析：答案是B.同時還須注意,從句的引導詞必須始終置於句首,而且how和被修飾的詞excited不能分裂開.
7.____ is a fact that English is being accepted as an international language.
A. There B. This C. That D. It
解析：所需詞至於句首,同時後面有that-從句（邏輯主語）,可見這裡應該用形式主語it,所以答案是D.think, find, consider, believe, feel等動詞後常可以帶it作形式賓語.例如：
Many people think it possible that a trade war between EU and the States will happen.
8.It is generally considered unwise to give a child ____ he or she wants.
A. however B. whatever C. whichever D. whenever
解析：答案是B,whatever引導一個賓語從句,並且作wants的賓語.這裡的whatever不能改成what,因爲題意想表達的顯然是「無論孩子要什麼就給他/她什麼事不明智的」,具有泛指的概念.同時要注意,這裡whatever也不能改用no matter what,因爲後者只能引導狀語從句.
9____ has helped to save the drowning girl is worth praising.
A. Who B. The one C. Anyone D. Whoever
解析：答案是D,whoever意爲「無論誰」,表泛指.比較下例：
I can’t remember at the moment who has said the words. （這裡的who表特定的某人）
10.I drove to Zhuhai for the air show last week.
— Is that ____ you had a few days off?
A. why B. when C. that D. where
解析：答案是A,why引導的從句作表語,同時why在從句中作原因狀語.這裡之所以選why,而不是when或 where等,唯一的依據便是句子的邏輯含義,及語境.
11.Do you remember ____ he came?
—Yes, I do, he came by car.
A. How B. when C. that D. if
解析：答案是A,從答語 「he came by car」可知這裡問的是「he」來的方式,所以用how引導.
12.It was a matter of ____ would take the position.
A. who B. whoever C. whom D. whomever
解析：答案是A.這是一個含賓語從句的複合句,作介詞of賓語的,是後面的整個句子,而不是賓語從句的引導詞,由於這裡引導詞在從句中作主語,所以要用主格who（作賓語時自然要用whom）.
13.Our country has thousands of excellent scientists, most of (whom) have received higher education at home.
這是一個「介詞+關係代詞」引導的定語從句；引導定語從句的是「most of+關係代詞」而不只是這個關係代詞,同時這個引導詞又作介詞of的賓語,所以要用賓格whom.（注意與介詞後面的賓語從句的引導詞的用法進行比較和區別.）
14____ you have seen both fighters, ____ will win?
A. Since; do you think who B. As; who you think
C. When; whoever D. Since; who do you think
解析：根據上面的講解,不難知道答案是D.其中do you think是插入成分,其餘部分是賓語從句,作think的賓語；由於引導詞在從句中作主語,所以要用主格who（不用whom）.
15.China’s success in manned-spacecraft travel shows ____ our country has become one of the greatest powers in space research.
A. what B. which C. 不填 D. it that
解析：該句中的從句作shows的賓語,是賓語從句,又因爲從句中不缺主、賓語,所以只能用that引導；又因引導賓語從句時that可以省略,所以答案是C
16Then arose the question ____ we were to get so much money.
17This the house ____ the great man Mao Zedong was born 110 years ago.
A. where B. that C. about which D. in which
解析：答案分別是(1) A (2) A/D.先行詞與where, when概念一致時,是定語從句,（2）中的house與where同表地點,且這個關係副詞where或when可以用「介詞+which」的形式代替,所以答案A 和D都可以引導.（1）題中的question與where不表同一概念,可見是同位語從句,所以where不能改用「介詞+which」的形式.
18
It is generally considered unwise to give a child ____  he or she wants．
A．whatever B．no matter what
C．whenever D．no matter when
此題應選A.容易誤選B.選項C,D顯然是錯的,因爲句中的wants缺賓語,而C,D兩項不能作賓語.至於C,D的區別,可這樣描述：no matter what只能引導狀語從句,而不引導名詞性從句.而whatever既可引導名詞性從句（＝anything that）,也可引導狀語從句（＝no matter what）：
19I think ____ he needs is more practice．
—Yes． ____ he needs more practice is clear．
A．what, What B．that,That
C．what, That D．that, What
此題應選C.其餘三項均可能被誤選.What和that都可以引導名詞性從句,但有區別：
1．what引導名詞從句時,它在從句中要充當句子成分（主語、賓語等）,而that引導名詞從句時,它在從句中不能充當句子成分.
2．what引導名詞從句時,它有詞義（表示：什麼；所…的[東西]）；而that引導名詞從句時,它沒有詞義.
20.____ we'll go camping tomorrow depenps on the weather．
A．If B．Whether C．That            D．When
此題應選B.容易誤選A,C.
1．關於if與whether：兩者都可引導賓語從句,常可換用；但若引導主語從句,則用whether（不用if）,排除A.
21.he said at the meeting astonished everyone present．
A．What            B．That          C．If           D．Whether
此題應選A.選項C（if）顯然不能選,因爲if通常不能引導主語從句；選項B（that）和D（whether）雖然都可以引導主語從句,但兩者除了意思不合題意外,還有它們在主語從句中都不充當句子成分,而此句中的he said缺賓語.
22._______ we can't get seems better than _______ we have.
A. What; what B. What; that
C. That; that D. That; what
分析: (注:劃線的選項爲最佳答案,下同.)在名詞性從句中that與what的區別是:that在名詞性從句中不作句子成分,只起連接作用;而what在名詞性從句中不僅起連接作用,而且作句子成分.句子的意思是:我們不能得到的似乎比我們已經擁有的要好.此題考查了兩個名詞性從句:主語從句和賓語從句,what在這兩個名詞性從句中都作賓語.
23._______ is a fact that English is being accepted as an international language.
A. There B. This C. That D. It
分析:在這種名詞性從句中爲了保持句子的平衡,往往用先行詞it作形式主語或形式賓語,而把真正的主語或賓語放到後面,尤其是that引導的主語從句往往用先行詞it作形式主語.此句也可以改寫爲:That English is being accepted as an international language is a fact.
24. I hate _______ when people talk with their mouths full.
A. it B. that C. this D. them
分析:此題考查的是用先行詞it作形式賓語,而把真正的賓語從句放到後面.其他幾個詞均不能作形式賓語.
25.The photographs will show you _______ .
A. what does our village look like
B. what our village looks like
C. how does our village look like
D. how our village looks like
分析:在名詞性從句中,除了關聯詞要提到句首之外,一律要用陳述句語序.當關聯詞含疑問意義時,有的學生就會受習慣影響錯誤地使用疑問句語序.克服這種錯誤的關鍵是要找准從句中的主語和謂語.本題句子的意思是:這些照片會告訴你我們村子是什麼樣.本題中根據引導詞what要作介詞like的賓語,而副詞how不能作介詞like的賓語,所以首先排除C、D,而A項是疑問句語序,故只能選B
26.
_______ we'll go camping tomorrow depends on the weather.
A. If B. Whether C. That D. Where
分析:句子的意思是:我們明天是否去野營要視天氣而定. whether與if當"是否"講時的區別是:在引導賓語從句時兩者可以互換,但在引導主語從句、表語從句和同位語從句以及介詞後面的賓語從句或後面緊跟or not時通常只能用whether,而不能用if.
27.
What the doctors really doubt is _______ my mother will recover from the serious disease soon.
A. when B. how C. whether D. why
分析:本題句子的意思是:醫生真正懷疑的是我母親是否能很快從重病中恢復過來.whether引導的是表語從句.
28: It worried her a bit _______ her
A. while B. that C. if D. for
分析:本題句子的意思是:頭髮變白使她有點兒不安.It作形式主語,that引導的是主語從句.whether, if以及that引導的名詞性從句的區別是:whether與if(當"是否"講時)引導的名詞性從句含有疑問意義;而that引導的名詞性從句不含有疑問意義.
29She expressed the she would travel in Dalian again.
A.hope it B.whether C.hope D.hope that
答案是D
30.May I ask you a question we are to get the book needed?
A.what B.which C.where D.if
答案是C
