一、由that引導(dǎo)的名詞性從句

(Ⅰ) that 引導(dǎo)的主語從句：引導(dǎo)主語從句的 that 在從句中沒有任何具體意義，僅僅起引導(dǎo)詞作用，在從句中不充當(dāng)任何成份，但不可省略。

（1）____ fashion differs from country to country may reflect the cultural differences from one aspect. (02上海春季)

A. What B. That C. This D. Which

[解析]這是個(gè)主語從句。因?yàn)橹髡Z從句句意完整，只缺一個(gè)引導(dǎo)詞，所以用that。這句話的意思是“國與國之間的時(shí)裝差異可以從一個(gè)方面反映出其文化的差異”。故答案為[B]。

[注意] 但為了避免“頭重腳輕“， 特別是主語從句太長，常用形式主語it來保持句子平衡。

（2）It has been proved ____ eating vegetables in childhood helps to protect you against serious illnesses in later life? (08上海卷)

A. if B. because C. when D. that

[解析]it是形式主語，代替由that引導(dǎo)的主語從句，故答案為[D]。

(Ⅱ) that引導(dǎo)的賓語從句：引導(dǎo)的賓語從句的 that 在從句中沒有任何具體意義,僅僅起引導(dǎo)詞作用，常可省略（尤其是從句簡短時(shí)）；但如果賓語從句很復(fù)雜，句中有多個(gè)狀語時(shí)或者有多個(gè)并列的賓語從句時(shí)，賓語從句前的that一般不省略。

With his work completed, the businessman stepped back to his seat, feeling pleased ____ he was a man of action.(06湖南卷)

A. which B. that C. what D. whether

[解析]分詞feeling pleased后面缺少賓語，而這個(gè)賓語從句句意完整。故答案選[B]。

[注意] take/hide/see to/insist on/depend on/count on 等后接that引導(dǎo)的賓語從句時(shí), 其后必須冠以形式賓語it。

You may depend on ____ that all the goods will be shipped abroad in time.

A. it B. them C. this D. /

Key:[A]

(Ⅲ) that引導(dǎo)的表語從句：表語從句在句子中作表語,位于主句中的系動(dòng)詞之后。引導(dǎo)表語從句的 that 在從句中沒有任何具體意義 ，僅僅起引導(dǎo)詞的作用，that一般不省略。

The traditional view is ____ we sleep because our brain is “programmed” to make us do so. (07上海卷)

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

[解析]本題考查表語從句, 從句中句意完整, 故用that。所以答案為 [D]。

(Ⅳ)that 引導(dǎo)的同位語從句：同位語從句一般跟在某些抽象名詞后面, 對(duì)名詞作進(jìn)一步解釋,說明名詞所表示的具體內(nèi)容。常接同位語從句的名詞主要有：fact, idea, news, promise, decision, belief, condition, doubt, fear, hope, problem, proof, question, opinion, report, suggestion, thought, truth等。由that引導(dǎo)的同位語從句在從句中沒有任何具體意義,僅僅起引導(dǎo)詞的作用, 但that不可省略。

Along with the letter was his promise ____ he would visit me this coming Christmas. (04上海春)

A. which B. that C. what D. whether

[解析]此句是由that引導(dǎo)的從句作promise的同位語,解釋promise的具體內(nèi)容。而前面的主句又是一個(gè)倒裝句,這增加了試題的難度。故答案選[B]。

二、由what引導(dǎo)的名詞性從句

what引導(dǎo)名詞性從句既作連接代詞又在從句中充當(dāng)一定成分，在從句中可以充當(dāng)主語、表語或賓語；并且what不能省略，名詞性從句還要用陳述句的語序。

(Ⅰ)what 引導(dǎo)的主語從句：

____ he referred to in his article was unknown to the general reader. （07上海卷)

A. That B. What C. Whether D. Where

[解析]這是個(gè)主語從句。he referred to缺少賓語, what既引導(dǎo)主語從句,又作was unknown to the general reader的主語。故答案選[B]。

(Ⅱ)what 引導(dǎo)的表語從句：

Great changes have taken place in that school. It is no longer ____ it was 20 years ago, ____ it was so poorly equipped. (05安徽卷)

A. what; when B. that; which C. what; which D. which; that

[解析]第一空由what引導(dǎo)表語從句，what作is的表語且作was的表語; 第二空由when引導(dǎo)定語從句。故選［A］。

(Ⅲ)what引導(dǎo)的賓語從句：

The companies are working together to create ____ they hope will be the best means of transport in the 21st century.(08北京卷)

A. which B. that C. what D. who

[解析]這是一個(gè)賓語從句，what在句中引導(dǎo)賓語從句，what既作create的賓語，又作will be的主語；如用which則有一定的范圍。故答案為[C]。

(Ⅳ)連詞what和that引導(dǎo)名詞性從句的差異：

that在從句中無實(shí)際意義，也不充當(dāng)任何成分，只起連接主從句的作用；如果由that引導(dǎo)賓語從句，?？墒÷?；如引導(dǎo)主語從句、表語從句或同位語從句，that不能省略。what引導(dǎo)名詞性從句，具有雙重功能（既是連詞又在句中充當(dāng)成分），它既可指人，也可指物。用于指人時(shí)，what=the person(s) that,用于指物時(shí)，what=the thing(s) that。what可以引導(dǎo)主語從句、賓語從句或表語從句。

(1)Choosing the right dictionary depends on ____ you want to use it for.(07江蘇卷)

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

[解析]這是一個(gè)賓語從句，what在句中作介詞for的賓語。故答案為[A]。

(2)You can only be sure of ____ you have at present; you cannot be sure of something ____ you might get in the future.(07 安徽卷)

A. that; what B. what; / C. which; that D. /; that

[解析]第一空考查賓語從句，作從句的賓語，所以用what；第二空考查定語從句，在從句中作get的賓語，且先行詞是不定代詞something，所以只能用that引導(dǎo)或省略，故答案選[B]。

三、由which引導(dǎo)的名詞性從句

which在名詞性從句中充當(dāng)一定的成分，并且有實(shí)在意思，指代有一定范圍的人或物，不可省略。

(1)The question is which team will win the champion.

(2)I have no idea which class he is in.

四、由whether與if引導(dǎo)的名詞性從句

通常whether和if都可以引導(dǎo)賓語從句；但在引導(dǎo)主語從句、表語從句和同位語從句和介詞后面的賓語從句以及后面跟or not時(shí)只能用whether而不能用if。

(1)We havent settled the question of ____ it is necessary for him to study abroad. (06江蘇卷)

A. if B. where C. whether D. that

Key：[C]

(2)____ well go camping tomorrow depends on the weather.

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

Key：[C]

五、由whoever/whatever/whichever引導(dǎo)的名詞性從句

whoever, whatever和whichever 均可引導(dǎo)主語從句、賓語從句和表語從句, 且在句中充當(dāng)一定的成分。whoever=no matter who(anyone who); whatever=no matter what(anything that); whichever=no matter which(anything that/anyone who)。

(1)____ wants to stay in a hotel has to pay their own way.

(08 浙江卷)

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

[解析]這是由whoever引導(dǎo)的主語從句。whoever作wants的主語，又作has to pay的主語；anyone與the one作先行詞，關(guān)系代詞作主語不能省略，故答案選 [C]。

(2)Could I speak to ____ is in charge of International Sales, please? (07 山東卷)

A. anyone B. someone

C. whoever D. no matter who

[解析]這是由whoever引導(dǎo)的賓語從句。whoever作介詞to的賓語，又作is的主語；anyone與someone作先行詞，關(guān)系代詞作主語不能省略，no matter who只能引導(dǎo)讓步狀語從句，不能引導(dǎo)名詞性從句。故答案選[C]。

(3)The employers often give the job to ____ they believe have work experience with a strong sense of duty.

A. whoever B. whomever C. who D. those who

[解析]此句的意思是“雇主經(jīng)常把工作提供給他們認(rèn)為有工作經(jīng)驗(yàn)且有強(qiáng)烈責(zé)任感的人”而不是把工作提供給任何人。所以答案選 [D]。

(4)Here are all the books I have. You may borrow ____ you like.

A. that B. which C. however D. whichever

[解析]whichever所指代的對(duì)象有一定的范圍。根據(jù)句意“你可以借你喜歡的任何一本書”而不是某一本書。故答案選[D]。

六、考查其它的連接副詞

連接副詞在主語從句中起連詞作用，同時(shí)又在從句中充當(dāng)一定的句子成分。選用這些連接副詞的關(guān)鍵是：所選的這個(gè)詞必須符合句子的邏輯要求。

The last time we had great fun was ____ we were visiting the Water Park. (08天津卷)

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

[解析]由于從句主干成分齊備，只能選用狀語，由主句中The last time推測，應(yīng)用when引導(dǎo)表語從句，作時(shí)間狀語。故答案選[C]。
