9、別引導(dǎo)詞說明從屬連詞that,whether兩者在從句中均不做成分,只起連接作用;that無實義,whether表示“是否”連接代詞who,what,which,whoever,whatever等在從句中做主語、賓語、表語、定語等成分類別引導(dǎo)詞說明連接副詞when,where,how,why等在從句中做時間、地點、方式、原因狀語等成分(1)由連詞that引導(dǎo)的主語從句:引導(dǎo)詞that無含義,在句中不做成分,不可以省略。That you will win the medal seems unlikely.你獲得獎牌看起來是不可能的。That you are so indifferent both

10、ers me.你如此冷淡使我很煩惱。(2)由連詞 whether引導(dǎo)的主語從句:whether表示“是否”,在句中不做成分,不可以省略。Whether she is coming is still unknown.她來不來還不知道。(3)由連接代詞who,whose,whom,which,what,whoever,whomever,whichever,whatever引導(dǎo)的主語從句:連接代詞在句中起名詞作用,充當(dāng)一定成分。What you need is more practice.你所需要的是更多的訓(xùn)練。Whatever we do is to serve the people.我們無論做什

11、么都是為人民服務(wù)。(4)由連接副詞when,where,why,how引導(dǎo)的主語從句:連接副詞有含義,在句中做狀語。When they will come hasnt been made public.他們什么時候來還沒有公之于眾。溫馨提示主語從句中連接詞的選擇技巧:在確定主語從句中連接詞的時候,可以根據(jù)連接詞在從句中所做的語法成分和連接詞在從句中的意義兩方面進行考慮。2.it做形式主語為了避免主語顯得過長,尤其是陳述句做主語從句時,可以用it做句子的形式主語,把主語從句移到句子的末尾。句型說明It +系動詞+形容詞+主語從句.常用于此句型的形容詞有important,(un)likely,p

12、ossible,necessary,natural,wrong等It+系動詞+名詞+主語從句.常用于此句型的名詞有fact,idea,honour,question,pity等句型說明It+系動詞+過去分詞+主語從句.常用于此句型的過去分詞有known,proved,said,decided,suggested,thought,reported等It+不及物動詞+主語從句.常用于此句型的動詞有appear,happen,seem,occur,matter等Its possible that he has been to Beijing.他有可能去過北京。Its a pity that you

13、didnt attend the meeting.你沒參加這次會議太可惜了。It is reported that a space station will be built on the moon in years to come.報道說未來幾年里月球上將建造空間站。It seems that it is going to rain.看起來好像要下雨。溫馨提示(1)在“It + 系動詞 + 形容詞 + 主語從句.”句型中,如果形容詞為necessary,important,strange,natural等時,從句謂語動詞常用“(should+)動詞原形”。It is important th

14、at he (should) know about this.他應(yīng)該知道此事是重要的。(2)在“It + 系動詞 + 過去分詞 + 主語從句.”句型中,如果過去分詞為suggested,advised,ordered,requested,required等時,從句謂語動詞使用“(should+)動詞原形”。It is suggested that the sports meeting(should) be put off.有人建議推遲舉行運動會。三、主語從句中應(yīng)注意的問題1.從句要用陳述語序How he succeeded finally is still a puzzle.他最后是如何成功的

15、仍然是個謎。2.主語為從句的主謂一致(1)主語為從句時,謂語動詞一般要用單數(shù)形式,但如果what引導(dǎo)的從句做主語,代表復(fù)數(shù)概念(?？蓮谋碚Z上看出)時,謂語動詞常用復(fù)數(shù)形式。What I need is your help.我所需要的是你的幫助。What the school needs most are books.這所學(xué)校最需要的是書。(2)如果由and連接兩個或兩個以上的主語從句做主語時,謂語動詞用復(fù)數(shù);由兩個或多個連接詞引導(dǎo)一個主語從句時,謂語動詞用單數(shù)。When they will start and where they will go have not been decided y

16、et.他們將在什么時候動身以及要去哪里還沒定下來。When and where they will hold the meeting is not clear.他們何時何地召開會議還不清楚。3.需要辨別以下幾組引導(dǎo)詞(1)whatever和whoeverwhatever和whoever可以引導(dǎo)主語從句,并在從句中做主語、賓語、表語等。此外,它們還可以引導(dǎo)讓步狀語從句,可以轉(zhuǎn)換成no matter what/who的形式。Whatever she did was right.她做的一切都是對的。(主語從句)Keep calm,whatever/no matter what happens.不管發(fā)

17、生什么事都要保持鎮(zhèn)靜。(讓步狀語從句)(2)what和thatwhat既有引導(dǎo)主語從句的作用,同時又在從句中做句子成分(主語、賓語、表語等)。這時what相當(dāng)于all that/everything that.,常譯成“的(東西、事情、話等)”;而that只起連接作用,本身無實際意義,在從句中也不擔(dān)當(dāng)任何句子成分。但that引導(dǎo)的主語從句放在句首時,不能省略that。What surprised me surprised him too.令我吃驚的是,他也很吃驚。(what做主語)That he is still alive is a wonder.他還活著,真是奇跡。即 學(xué) 即 練完成句子(

18、1)很可惜你不能來參加我的生日聚會。Its a pity that you cant attend my birthday party.(2)有人建議這位老人到鄉(xiāng)村休息一下。Its suggested that the old man should go to the countryside to have a rest.(3)在我看來你好像不贊成這個計劃。It seems to me that you disagree with the plan.(4)我們在哪兒開會都無所謂。Where we shall have the meeting makes no difference.(5)他拒絕
