14、ed?woman?→?subject 3.?學(xué)習(xí)主語從句 一、由?what（whatever，whoever）等代詞引導(dǎo)的主語從句。 What?they?are?after?is?money. 他們追求的是金錢。 Whatever?was?said?here?must?be?kept?secret. 這里說的話都應(yīng)當(dāng)保密。 二、由連詞?that?引導(dǎo)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?i

15、t?的結(jié)構(gòu)。 That?money?doesn't?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?doesn't?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(jī)什么時候起 飛宣布了沒有？ 注意： 1）選用?what?還是用?that?引導(dǎo)主語從句要根據(jù)關(guān)聯(lián)詞在從句中是否擔(dān)任成分而 定。且?what（

16、以及?whatever，whoever?等）引導(dǎo)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(dǎo)的主語從句中作賓語。） That?China?is?a?great?socialist?country?is?well?known.（=It’s?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(dǎo)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(dǎo)的強調(diào)句與?it?作形式主語的復(fù)合句不可混淆。it?引導(dǎo)的強調(diào)句是用 來對

17、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(fù)合句結(jié)構(gòu)： *It?is+形容詞（nec?essary?，strange，important，wonderful，possible，likely， 等）+that?從句，從句中常用虛

18、擬語氣。 It’s?necessary?that?he?write?something?in?English.他用英語寫點東西是 必要的。 It’s?strange?that?she?did?not?go?to?school?yesterday.奇怪的是她昨天沒 去上學(xué)。 *It?is+名詞（a?fact，a?pity?，no wonder，good?news，等）+that?從句 It's?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

19、，unknown?等）+that?從句 Its?said?that?our?English?teacher?will?go?abroad?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(dǎo)的從句作主語、代 表復(fù)數(shù)概念（常可從表語上看出）時，謂語動詞則常用復(fù)數(shù)形式： What?we?nee

20、d?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(dǎo)的主語從句。 When?they?will?come?hasn't?been?made?public.他們什么時候回來還沒有宣布。 Whether?I’ll?attend?the?meeting?hasn’t?been?decided.=It?hasn’t?been decided?whether(if)?I’ll?attend?the?meeting.我是否參加會議還未決定。
