高一名詞性從句專項(xiàng)練習(xí)

1、名詞性從句專項(xiàng)復(fù)習(xí)主語從句、表語從句、賓語從句、同位語從句，在整個(gè)句子中所起的作用，相當(dāng)于一個(gè)名詞因此，這四種從句通稱為名詞性從句。引導(dǎo)名詞性從句的連接詞可分為三類：連接詞that，whether, if （不充當(dāng)從句的任何成分）連接代詞：what, whatever, who, whoever, whom, whose, which. 連接副詞：when, where, how, why名詞性從句連接詞的選用(一) that 和 what的選用：that 和 what都可引導(dǎo)所有的名詞從句。但是，what除起連接作用外，還在名詞性從句中充當(dāng)成分，可做從句的主語、賓語、或表語。而that在名詞

2、性從句中不充當(dāng)任何成分，只起連接作用。that / what1._ he wants is a book.2. _ he wants to go there is obvious.3.The result is _ we won the game.4.This is _ we want to know.5.Is _ he told us true ?6.We should pay attention to _ the teacher is saying.7. I have no doubt _ he will come.8. I have no idea _ he did that after

3、noon.(二） if 和whether 的選用不能使用if 的情況：a. 主語從句b. 表語從句c. 同位語從句d. 介詞后的賓語從句e. whether to do 做動(dòng)詞賓語不能用if to do.f .whether or not 連在一起引導(dǎo)賓語從句時(shí)不用if.1. I asked her _ she had a bike.2._ we will hold a party in the open air tomorrow depends on the weather.3. Were worried about _ he is safe.4. I dont know _ he is w

4、ell or not.5. I dont know _ or not he is well.6. The question is _ he should do it.7.The doctor can hardly answer the question _ the old man will recover soon.8. I dont know _ to go.（三）其它連接代詞和副詞的連用 主要根據(jù)名詞性從句中的具體意義,正確的選擇who、which、when、where、why、how 等連接詞，這些連接詞既具有疑問含義，又起連接作用，同時(shí)在從句中充當(dāng)各種成分。我們何時(shí)舉行運(yùn)動(dòng)會(huì)還沒有決定

5、。_ we shall hold our sports meeting is not decided.我不知道昨天誰打破了玻璃。I dont know _ broke the glass yesterday.我不知道他長的什么樣子。I have no idea _ he looks like.這就是我忘記眼鏡的地方。This is _ I left my glasses.（四）引導(dǎo)詞that 的省略that 可省略的情況：單個(gè)賓語從句中的that可省略that不可省略的情況：a. 主語從句b.表語從句c.同位語從句d.用it做形式賓語的賓語從句e. 并列的賓語從句中的后幾個(gè)從句的,引導(dǎo)詞tha

7、句的引導(dǎo)和辨別1.同位語從句的格式：n.+ 連接詞 + 從句2.能接同位語從句的名詞有：fact、idea, news, information, order, belief, suggestion, advice等.3.連接詞通常是that,也可根據(jù)含義選用 whether, what, when, where 等來引導(dǎo)同位語從句.1. I have no idea _ he comes from.2. He cant answer the question _ he got the money.3.He gave us many suggestions _ we should get up

8、 earlier and take more exercise.4.I have no doubt _ he will win.5. I have some doubt _ he will win.（六） 同位語從句和定語從句的區(qū)別1.定語從句是先行詞的修飾語，它不涉及先行詞的具體內(nèi)容。定語從句中that不但起連接作用，而且在定語從句中充當(dāng)一個(gè)句子成分，充當(dāng)從句的賓語成分時(shí)可省略。2.同位語從句對(duì)中 心詞的內(nèi)容作進(jìn)一步的解釋和說明，表明中心詞的具體內(nèi)容。引導(dǎo)同位語從句的that 在同位語從句中不做任何成分,只起連接作用,無具體含義,且不可省略.1.We expressed the hope t

9、hat they had expressed.2. We expressed the hope that they would come to China again.1.The information has been announced that more middle school graduates will be admitted into university.2.The information that he revealed at the meeting is of great value.（七） 名詞demand, suggestion, proposal, advice等詞

10、后的同位語從句的語氣要用虛擬語氣,結(jié)構(gòu)為 should + do, should 可省略 He gave me a suggestion that I ( should ) be calm now.(八） 賓語從句的時(shí)態(tài)呼應(yīng)1. 如果主句時(shí)態(tài)是現(xiàn)在時(shí)或?qū)頃r(shí),從句謂語可根據(jù)句意需要而選用任一種時(shí)態(tài). a .他相信他的夢(mèng)想總有一天會(huì)實(shí)現(xiàn)的. He believes _ . b .請(qǐng)告訴我你昨天這個(gè)時(shí)候在干什么. Please tell me _.Practice: 1. It now appears _ they are in need of help.A. that B. which C. w
