9、別引導(dǎo)詞說(shuō)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(wú)實(shí)義,whether表示“是否”連接代詞who,what,which,whoever,whatever等在從句中做主語(yǔ)、賓語(yǔ)、表語(yǔ)、定語(yǔ)等成分類(lèi)別引導(dǎo)詞說(shuō)明連接副詞when,where,how,why等在從句中做時(shí)間、地點(diǎn)、方式、原因狀語(yǔ)等成分(1)由連詞that引導(dǎo)的主語(yǔ)從句:引導(dǎo)詞that無(wú)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(jiǎng)牌看起來(lái)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(yǔ)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(lái)不來(lái)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(yǔ)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(wú)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(yǔ)從句:連接副詞有含義,在句中做狀語(yǔ)。When they will come hasnt been made public.他們什么時(shí)候來(lái)還沒(méi)有公之于眾。溫馨提示主語(yǔ)從句中連接詞的選擇技巧:在確定主語(yǔ)從句中連接詞的時(shí)候,可以根據(jù)連接詞在從句中所做的語(yǔ)法成分和連接詞在從句中的意義兩方面進(jìn)行考慮。2.it做形式主語(yǔ)為了避免主語(yǔ)顯得過(guò)長(zhǎng),尤其是陳述句做主語(yǔ)從句時(shí),可以用it做句子的形式主語(yǔ),把主語(yǔ)從句移到句子的末尾。句型說(shuō)明It +系動(dòng)詞+形容詞+主語(yǔ)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(dòng)詞+名詞+主語(yǔ)從句.常用于此句型的名詞有fact,idea,honour,question,pity等句型說(shuō)明It+系動(dòng)詞+過(guò)去分詞+主語(yǔ)從句.常用于此句型的過(guò)去分詞有known,proved,said,decided,suggested,thought,reported等It+不及物動(dòng)詞+主語(yǔ)從句.常用于此句型的動(dòng)詞有appear,happen,seem,occur,matter等Its possible that he has been to Beijing.他有可能去過(guò)北京。Its a pity that you

13、didnt attend the meeting.你沒(méi)參加這次會(huì)議太可惜了。It is reported that a space station will be built on the moon in years to come.報(bào)道說(shuō)未來(lái)幾年里月球上將建造空間站。It seems that it is going to rain.看起來(lái)好像要下雨。溫馨提示(1)在“It + 系動(dòng)詞 + 形容詞 + 主語(yǔ)從句.”句型中,如果形容詞為necessary,important,strange,natural等時(shí),從句謂語(yǔ)動(dòng)詞常用“(should+)動(dòng)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(dòng)詞 + 過(guò)去分詞 + 主語(yǔ)從句.”句型中,如果過(guò)去分詞為suggested,advised,ordered,requested,required等時(shí),從句謂語(yǔ)動(dòng)詞使用“(should+)動(dòng)詞原形”。It is suggested that the sports meeting(should) be put off.有人建議推遲舉行運(yùn)動(dòng)會(huì)。三、主語(yǔ)從句中應(yīng)注意的問(wèn)題1.從句要用陳述語(yǔ)序How he succeeded finally is still a puzzle.他最后是如何成功的

15、仍然是個(gè)謎。2.主語(yǔ)為從句的主謂一致(1)主語(yǔ)為從句時(shí),謂語(yǔ)動(dòng)詞一般要用單數(shù)形式,但如果what引導(dǎo)的從句做主語(yǔ),代表復(fù)數(shù)概念(?？蓮谋碚Z(yǔ)上看出)時(shí),謂語(yǔ)動(dòng)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(shū)。(2)如果由and連接兩個(gè)或兩個(gè)以上的主語(yǔ)從句做主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用復(fù)數(shù);由兩個(gè)或多個(gè)連接詞引導(dǎo)一個(gè)主語(yǔ)從句時(shí),謂語(yǔ)動(dòng)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(shí)候動(dòng)身以及要去哪里還沒(méi)定下來(lái)。When and where they will hold the meeting is not clear.他們何時(shí)何地召開(kāi)會(huì)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(yǔ)從句,并在從句中做主語(yǔ)、賓語(yǔ)、表語(yǔ)等。此外,它們還可以引導(dǎo)讓步狀語(yǔ)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(duì)的。(主語(yǔ)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(yǔ)從句)(2)what和thatwhat既有引導(dǎo)主語(yǔ)從句的作用,同時(shí)又在從句中做句子成分(主語(yǔ)、賓語(yǔ)、表語(yǔ)等)。這時(shí)what相當(dāng)于all that/everything that.,常譯成“的(東西、事情、話(huà)等)”;而that只起連接作用,本身無(wú)實(shí)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(yǔ)從句放在句首時(shí),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(yǔ))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(lái)參加我的生日聚會(huì)。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(lái)你好像不贊成這個(gè)計(jì)劃。It seems to me that you disagree with the plan.(4)我們?cè)谀膬洪_(kāi)會(huì)都無(wú)所謂。Where we shall have the meeting makes no difference.(5)他拒絕
