語法復(fù)習(xí)詳案名詞性從句

1、【語法復(fù)習(xí)詳案】 名詞性從句(Noun Clauses)考點梳理上大市北顏一、相關(guān)基礎(chǔ)知識1. 英語句子分為3大類：_、_、_。若句中含有插入語成分，此類句子通常被稱為_。2. 復(fù)合句是由1個_加個或幾個_復(fù)合而成的句子。從句只用作句子的一個成分，不能獨立存在。根據(jù)從句在句子中的作用，可以將從句分為3類：_、_、_。3. 名詞性從句包括4種_從句、_從句、_從句和_從句。4. 名詞性從句的時態(tài)問題(1) 由于以when引導(dǎo)的時間狀從和以if引導(dǎo)的條件狀從，要用一般現(xiàn)在時表示將來意義，而不能直接使用一般將來時態(tài)（即“主將從現(xiàn)/主現(xiàn)從現(xiàn)”原則），所以許多同學(xué)容易受此影響在when和if引導(dǎo)名詞性從

2、句時也用現(xiàn)在時表示將來意義。以如下幾題為例： I dont know if he _ or not tomorrow.A. come B. comes C. will comeD. is coming I dont know if she _, but if she _ I will let you know.A. comes, comesB. will come, will comeC. comes, will comeD. will come, comes“When he _ is not known yet.” “But when he _, he will be warmly welc

3、omed.”A. comes, comesB. will come, will come C. comes, will comeD. will come, comes(2)賓語從句中，當(dāng)主句為現(xiàn)在或?qū)頃r態(tài)時，賓語從句可以和主句的時態(tài)不一致，而是根據(jù)實際需要用不同的時態(tài)。我不在乎他是否會回來。(care)譯：我聽說?；@球隊前天贏得了決賽。(hear)譯：(3)賓語從句中，當(dāng)主句為一般過去時態(tài)時，賓語從句通常要用過去的某種時態(tài)（包括一過/過完/過進(jìn)/過將）與之呼應(yīng)，然而當(dāng)賓從表示客觀真理/普遍現(xiàn)象/諺語格言時，賓從只能用一般現(xiàn)在時。老師告訴我們他知道一切。譯：老師告訴我們光比聲音傳播得快。譯：(

4、4)名詞性從句若使用虛擬語氣，也會出現(xiàn)主句和從句時態(tài)不一致的現(xiàn)象。詳見“虛擬語氣”語法詳案，此處從略。5. 名詞性從句中的主謂一致（高頻考點）(1) 單個主語從句作主語，相當(dāng)于單數(shù)第三人稱作主語，謂語動詞用單數(shù);(2) 由and 連接兩個或兩個以上的主語從句作主語時，謂語動詞用復(fù)數(shù)；(3) 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)。如： When the meeting will begin _not been decided yet. （have）When they will start and where they go _not been decided yet. ( hav

5、e)When and where the meeting will begin _not been decided. （have）6. 名詞性從句的語序問題 名詞性從句總是用陳述句詞序，則不能使用疑問句詞序，尤其是當(dāng)名詞性從句由“疑問詞”引導(dǎo)時，不能受疑問句的影響而誤用疑問句詞序：誤：I didnt know where did he live.正：I didnt know where he lived. 我不知道他住哪兒。誤：Who will he marry remains unknown.正：Who he will marry remains unknown. 他同誰結(jié)婚還不知道。分享給

6、你的朋友吧：· i貼吧 · 新浪微博· 騰訊微博· QQ空間· 人人網(wǎng)· 豆瓣· MSN對我有幫助7. 名詞性從句的連接詞主要包括以下幾類：(1) 連接代詞：who, whom, whose, what, which。有詞義，在從句中擔(dān)任成分(如_)。例句助記： 我不知道她是誰。(who) ( _從句 )譯： 我忘了昨天遇到誰了。(whom) ( _從句 )譯： 告訴我這是誰的書。(whose) ( _從句 )譯： 她說的是對的。(what)( _從句 )譯： 告訴我你最近讀了什么書。(what) ( _從句 )譯： 哪個足

8、（表從），because（表從）。【切記】:that 無詞義，在從句中不擔(dān)任成分，表明從句內(nèi)容的_性，有時可省略。明年9月他將考入理想大學(xué)，這很明顯。(that)譯：相關(guān)真題（2009天津）:It is obvious to the students _ they should get well prepared for their future.A. as B. whichC. whetherD. thatwhether/if,有詞義(意為_)，在從句中不擔(dān)任成分，表明從句內(nèi)容的_性，不可省略。請告訴我他是否能考試及格。(whether)譯：是否我們能贏得決賽，還很難說。(whether)譯

9、：as if/though和because，有詞義，在名詞性從句中只能引導(dǎo)_，在從句中不擔(dān)任成分，也不可省略。她看上去似乎要哭了。(as if)譯：那是因為可能是練得太多了。(because)譯：此外，as if/though還可引導(dǎo)_狀從；because還可引導(dǎo)_狀從。她站在門邊，好像在等人。(as if)譯：因為生病，所以他沒能參加畢業(yè)典禮。(because)譯：(4)復(fù)合連接詞whoever, whichever, whatever（異常重要）既可引導(dǎo)名詞性從句，也可引導(dǎo)讓步狀從。具體為：引導(dǎo)名詞性從句引導(dǎo)讓步狀語從句whoever = _whoever = _whichever = _

10、whichever = _whatever = _whatever = _注意：whenever,wherever,however一般只引導(dǎo)讓步狀從，分別相當(dāng)于no matter when, no matter where, no matter how【知識梳理】1)whoever,whichever,whatever引導(dǎo)名從時，無疑問語義，且具有雙重功能：既在從句中充當(dāng)主/賓/定/表，也在主句中充當(dāng)主/賓/表（不可引導(dǎo)定從）。 無論誰先來都將得到這份禮物。(whoever，主從)譯： 班級里無論誰想要，都把這本書給他。(whoever,賓從)譯： 這是兩本詞典。無論你喜歡哪本都可以選。(wh

12、，有疑問語義，且功能單一，不能在主句中充當(dāng)某種成分，只能在所引導(dǎo)的從句中充當(dāng)主/賓/定/表。而whoever, whichever, whatever引導(dǎo)名詞性從句時，具有雙重功能，既在主句中充當(dāng)某種成分(主/賓/表)，同時又在所引導(dǎo)的從句中充當(dāng)主/賓/定/表。這是高考的一個熱點和難點，務(wù)必在理解的基礎(chǔ)上牢固掌握。試比較下列幾道真題： (1998上海高考真題)It was a matter of _ would take the position.A. who B. whoever C. whom D. whomever (1999上海高考真題)_ has helped to save the

That B. Those C. What D. Whether2. 多數(shù)情況下，為了保持句子平衡，避免出現(xiàn)“_”現(xiàn)象，從而違反英語的“_”原則，因此當(dāng)that引導(dǎo)主從時，往往由it作為_置于句首，而把真正的that主從放在句

27、atB. whereC. ifD. that 【相關(guān)知識歸納】(1) it作形式主語代替主語從句，主要是為了_，避免_且其關(guān)聯(lián)詞除_/_外，還包括_等It后的謂語若是be動詞，可以是be動詞的_形式。(2) it引導(dǎo)的強調(diào)句型，其關(guān)聯(lián)詞只能是_(強調(diào)人時可用_)此句型用于強調(diào)_語、_語和_語。It后必接be動詞，且只能是be動詞的2種形式：_和_?？傊瑥娬{(diào)句型的“金三點”（包括_、_、_）不可或缺，是強調(diào)句型的重要標(biāo)志。判斷一個句子是否強調(diào)句型的唯一方法就是：_試用強調(diào)句型對下列語句進(jìn)行強調(diào)：John might have bought a new book for Mary yesterd

29、uhan. 4）_從句、_從句中只能用whether。如： The question is whether they have so much money. We ought to discuss carefully the question whether we can do it or not. 5）whether常與or連用表示_，if不能這樣用。如：The question of whether they are male or female is not important. 【補充】whetheror還可引導(dǎo)狀從中的_。如：無論明天是否下雨，運動會都將按時舉行。(whether)譯

30、：_6）whether也可與_連用，但if不能。如： I have not decided whether to go or not. 7）_時用whether不用if。如： Thank you, but whether Ill be free Im not sure at the moment. 8）引導(dǎo)_從句時， 必須用if ，此時if不再表示“是否”，而意為“_”。If it rains tomorrow , we wont go to the Summer Palace .三、賓語從句(一) that引導(dǎo)的賓語從句1. that的省略情況(1)引導(dǎo)賓語從句的連詞that一般可省略。e.

31、g. I hope (that) everything is all right.(2) 然而，在以下幾種情況中that不能省略：A）當(dāng)that從句和主句謂語動詞之間有插入語，或者從句主語之間有插入語時，that不可省略。如：He judged that, because he was a child, he did not understand wine.B）當(dāng)that 從句與另一名詞性從句并列作賓語時，that不可省略。如：They believed that land did not belong to people but _ people belong to land.A. that

He often go to church on Sunday except that he is ill.2. that從句用作賓語，具體包括如下幾種形式：(1)動詞賓語。這里所說的動詞，包括了謂語動詞及非謂語動詞（非謂語動詞也能接賓語）

33、。各舉一例：I hear that they have gone to Beijing.Knowing that his father would come back, he tidied up his room.(2) 形容詞賓語。Im glad that you have recovered.Hes afraid that he will lose the chance.注意：其后常接that賓從的形容詞主要有sure, certain, happy, glad, afraid, aware, eager, anxious等。(3) 介詞賓語。that從句通常不能跟在介詞后而作賓語，但是在

34、介詞in、except、but、besides和save之后可以跟that從句，多已看作固定用法，須特別記憶：in that:except that:besides that:save that:but that:相關(guān)試題： He has not changed at all _ that he is no longer so talkative.A. but B. except C. despite D. apart The Chicago Buildings was different _ each of its stories was complete in itself.

41、se, guess, expect, fancy, imagine等，后接賓語從句，且主句的主語是_人稱時，賓從的否定詞須前移到主句中，即主句的謂動用否定式，而從句的謂動用肯定式。我想我并不認(rèn)識你。(think)譯：我相信他不回來。(believe)譯：我猜明天不會下雨。(guess)譯：切記：若謂語動詞為hope，賓語從句中的否定詞不能轉(zhuǎn)移。如下例：我想你沒有生病吧。(hope)譯：若謂語動詞為think, 也可以不用轉(zhuǎn)移。如下例：我認(rèn)為他不能完成這項重要且困難的工作。(think)譯：(2)賓語從句在出現(xiàn)否定轉(zhuǎn)移時，若構(gòu)成反義疑問句，需要注意哪些事項? 這種否定前移的復(fù)合句，在變成反意疑問

You dont believe you can get the first prize

43、, _?(二) wh-詞引導(dǎo)的賓語從句1. 作動詞賓語。這里的動詞包括謂語動詞和非謂語動詞（非謂也可接賓語）。我想知道你是否已經(jīng)遇到了他。(wonder)譯：我正在等著你告訴我這個項目將何時完成。(wait)譯：2作介詞賓語。關(guān)于他是怎樣通過駕駛考試的，他只字未提。(manage)譯：我不知道他所指的是什么。(aware)譯：我們都為他所做的感到驕傲。(proud)3. 作形容詞賓語。我不確定她為何拒絕了我們的邀請。(refuse)譯：(三) 含有插入語結(jié)構(gòu)的賓語從句We agreed to accept _ they thought was the best tourist guide.A.
