2017初中英語(yǔ)語(yǔ)法:賓語(yǔ)從句
考察的三個(gè)要點(diǎn):語(yǔ)序,時(shí)態(tài),關(guān)聯(lián)詞。
1.定義:用作賓語(yǔ)的從句叫賓語(yǔ)從句。
2.構(gòu)成:關(guān)聯(lián)詞+簡(jiǎn)單句。
3賓語(yǔ)從句的語(yǔ)序一定是陳述句語(yǔ)序。(who 作主語(yǔ)的從句本身就是陳述句語(yǔ)序)
4賓語(yǔ)從句在復(fù)合句中作主句的賓語(yǔ),連接賓語(yǔ)從句的連詞有that(that在口語(yǔ)中常省略)。 whether,if,和連接代詞what, which, who, whom及連接副詞when, where, how, why。
He knew(that) he should study hard.
他知道他應(yīng)該努力學(xué)習(xí)。
Can you tell me which class you are in?
您能告訴我,您在哪一班嗎?
He asked me if he could come in,
他問(wèn)我他是否能進(jìn)來(lái)。
5.引導(dǎo)賓語(yǔ)從句的關(guān)聯(lián)詞有三類:
(1)從屬連詞that.如:一般那情況下可以省略。
He told us that he felt ill.
I know he has returned.
注: that在引導(dǎo)賓語(yǔ)從句時(shí)也并不是任何情況下都可以省略。在以下情況下,that不能省略。
1.Everybody could see what happened and that Tom was frightened.
(and連接兩個(gè)賓語(yǔ)從句,that賓語(yǔ)從句放在and的后面時(shí),that不能省略。)
2.I know nothing about him except that he is from the south.
(that引導(dǎo)的賓語(yǔ)從句作介詞賓語(yǔ)時(shí),that不能省略。)
3.That he ever said such a thing I simply don’t believe.(that從句位于句首時(shí),that不可省略。)
我簡(jiǎn)直不相信他曾說(shuō)過(guò)這樣的話。
(2)從屬連詞if/whether.如:
I doubt whether he will succeed.
I don’t know if you can help me.
(3)連接代詞who,whom,whose,what,which,whoever,whatever,
whichever
連接副詞 where,when,how,why.
Who or what he was,Martin never learned.
I wonder what he’s writing to me about.
I’ll tell you why I asked you to come.
注意
1.如果賓語(yǔ)從句后還有賓語(yǔ)補(bǔ)足語(yǔ),則用it作形式賓語(yǔ),而將賓語(yǔ)從句后置。
We thought it strange that Xiao Wang did not come yesterday.
He has made it clear that he will not give in.
2.某些形容詞或過(guò)去分詞后常接賓語(yǔ)從句,這類形容詞或過(guò)去分詞有sure,glad,certain,pleased,happy,afraid,surprised,satisfied等,連詞that可省略。
I am not sure what I ought to do.
I’m afraid you don’t understand what I said.
I’m surprised that I didn’t see all that before.
Mother was very pleased her daughter had passed the exams.
3.連詞whether (…or not)或if引導(dǎo)的賓語(yǔ)從句
if和whether引導(dǎo)的賓語(yǔ)從句可以互換使用,但whether常和or not連用,
if一般不與or not連用。如:
I wonder whether it is true or not.我不知它是真是假。
用if引導(dǎo)賓語(yǔ)從句如果會(huì)引起歧義,應(yīng)避免使用if而用wheter.試比較:
Please let me know if you want to go.
Please let me know whether you want to go.
if從句可理解為賓語(yǔ)從句,意為“請(qǐng)告訴我你是否想去”;此句又可理解為條件狀語(yǔ)從句意為“如果你想去的話,請(qǐng)告訴我一聲”。
4.賓語(yǔ)從句的否定轉(zhuǎn)移。在think,believe,suppose,expect等動(dòng)詞后的賓語(yǔ)從句,有時(shí)謂語(yǔ)盡管是否定意思,卻不用否定形式,而將think等動(dòng)詞變?yōu)榉穸ㄐ问?。如?/p>
I don’t think you are right.
I don’t believe they have finished their work yet.
I don’t suppose he cares,does he? 我想他不在意,是嗎?
5.賓語(yǔ)從句的時(shí)態(tài)變化規(guī)律:
主句 從句
一般現(xiàn)在時(shí) 可根據(jù)需要用任何時(shí)態(tài)。
一般過(guò)去時(shí) 過(guò)去的某種時(shí)態(tài),例如:一般過(guò)去,過(guò)去進(jìn)行,過(guò)去完成,過(guò)去將來(lái)等
注意:說(shuō)到自然現(xiàn)象和普遍真理時(shí),用一般現(xiàn)在時(shí)
