8、at引導的主語從句。其中that一般不可省略，但若用it作形式主語， that從句后置時，則可省略。為避免頭重腳輕，我們傾向用it開頭，后接be，seem等。如果句子是疑問形式，就只能用帶it的結(jié)構(gòu)。That money doesnt grow on trees should be obvious.金錢不能從樹上長出來是顯而易見的。It is obvious（that）money doesnt grow on trees .顯而易見，金錢是不能從樹上長出來的。Has it been announced when the planes are to take off？飛機什么時候起飛宣布了沒有？

9、注意：1）選用what還是用that引導主語從句要根據(jù)關(guān)聯(lián)詞在從句中是否擔任成分而定。且what（以及whatever，whoever等）引導的主語從句一般不用it作形式主語。What he said is true.他說的是真的。（what在其引導的主語從句中作賓語。）That China is a great socialist country is well known.（=Its well known that）眾所周知，中國是一個偉大的社會主義國家。（that在其引導的主語從句中不作任何成分，也無詞義，只起連接作用。）2）it引導的強調(diào)句與it作形式主語的復合句不可混淆。it引導的強

10、調(diào)句是用來對句中某一成分加以強調(diào)，其結(jié)構(gòu)為：“It is（或was）+強調(diào)部分+that（或who）”強調(diào)句去掉It is（或was）that（或who）框架后，剩余部分為一個完整的句子。It was I that(who) met Mary in the street yesterday.是我昨天在街上遇見了瑪麗。(強調(diào)主語)3）常見的用it作形式主語的復合句結(jié)構(gòu)：*It is+形容詞（necessary，strange，important，wonderful，possible，likely，等）+that從句，從句中常用虛擬語氣。Its necessary that he write so

11、mething in English.他用英語寫點東西是必要的。Its strange that she did not go to school yesterday.奇怪的是她昨天沒去上學。*It is+名詞（a fact，a pity ，no wonder，good news，等）+that從句Its a pity that she should have said so.真遺憾她竟然會這么說。*It is+過去分詞（said，reported，decided，unknown等）+that從句Its said that our English teacher will go abroad

12、next week.據(jù)說我們英語老師下周要去出國。*It +不及物動詞（seems，appears，happens， matters等）+that從句It seems that she is in great need of help.看來她急幫忙。4）主語為從句時，一般要用單數(shù)謂語動詞形式；但如果引導的從句作主語、代表復數(shù)概念（?？蓮谋碚Z上看出）時，謂語動詞則常用復數(shù)形式：What we need is water. 我們需要的是水。What we need are useful books. 我們需要的是有用的書。三、由連接代詞或連接副詞（或if, whether）引導的主語從句。When

B 因謂語動詞depends on，說明go camping這件事尚未確定。主語從句在句首時，不用if，故用whether。2. A 本句兼考查主語從句與表語從句。3. C 此題中有兩個不是并列的動詞謂語，而Anyone和The person不是連接代詞，也不是關(guān)系代詞，所以先排除A和B；又whoever=the person who,故選C.4. A 本句考查“do what one can（do）”這一句型。用whatever代what語氣更強。5. C what引導主語從句，在從句中做主語，it是形式主語；that引導
