2019年高考英語一輪總復(fù)習(xí) 語法專項突破 考點精講 第九節(jié) 名詞性從句 考點一　名詞性從句連接詞的用法 1．連接詞的基本用法 (1)連接詞that在從句中沒有任何含義，只起連接作用，不作任何成分。 That he will e to the meeting made us excited. 他要來參加會議使我們大家很興奮。 (2)連接詞whether，if意為“是否”，只起連接作用，不作任何成分。若在兩者之間二選一，應(yīng)選擇whether。 Whether we will go there tomorrow depends on the weather. 我們明天是否去那里取決于天氣。 (3)連接代詞who，whom，whose，what，which，who(m)ever，whatever，whichever既起連接作用，同時又在從句中充當(dāng)主語、賓語、表語、定語等成分。 She didnt know what life in a foreign country would be like.她不知道外國的生活會是什么樣。 Whoever breaks the rule should be punished. 不論誰違反了規(guī)則都要受到懲罰。 (4)連接副詞when，where，why，how既起連接作用，同時又在從句中作狀語。 She has decided how she should settle the matter. 她已做出決定如何來解決這件事。 2．that與what的區(qū)別 that沒有詞義，也不作任何成分，當(dāng)從句意義完整，不缺任何成分時用that；what在從句中表示“……的(東西)”(有時候可以不譯)，在從句中充當(dāng)主語、賓語、表語、定語等成分。 That they need more oil is very clear. 很明顯，他們需要更多的油。 What they need is more oil. 他們需要的是更多的油。 3．who與whoever的區(qū)別 who在名詞性從句中表示“誰”；而whoever(謂語用單數(shù))＝anyone who，(謂語用單數(shù))＝those who(謂語用復(fù)數(shù))。 Who will be invited to the ceremony hasnt been decided. 邀請誰參加儀式還未定下來。 Give the dictionary to whoever(＝anyone who) needs it most. 把詞典給最需要的人。 考點二　主語從句 1．that引導(dǎo)的從句作主語時，常用it作形式主語，常見句式有。 (1)It＋系動詞＋形容詞(necessary/right/likely/unlikely/wrong/important/certain等)＋that從句。 It is necessary that a person should provide against a raining day. 一個人應(yīng)該居安思危、未雨綢繆。 (2)It＋ be＋名詞(短語)(a pity/a shame/no wonder等)＋that從句。 It is a pity that you cannot e to our party. 你不能來參加我們的聚會真是遺憾。 (3)It＋be＋過去分詞(said/told/reported/decided等)＋that從句。 It is reported that many people are homeless after floods. 據(jù)報道洪水過后很多人無家可歸。 (4)It＋特殊動詞(seem/appear/happen/occur/matter)＋that從句。 It seems that young people are more interested in pop music.年輕人似乎對流行音樂更感興趣。 2．其他連接詞引導(dǎo)主語從句時也可用it作形式主語。 If a person dose his best，it doesnt matter what people think of him.如果一個人盡了他最大的努力，那么人們?nèi)绾卧u價他并沒關(guān)系。 考點三　賓語從句 1．動詞find，feel，think，consider，make，believe等后有賓語補足語時，需要用it作形式賓語而將賓語從句后置。 I have made it a rule that I keep diaries. 我已把每天寫日記當(dāng)成了慣例。 2．有些動詞帶賓語從句時習(xí)慣上需要在賓語從句前加it，這類動詞有：hate，enjoy，like，love，dislike，appreciate，see to等。 I would appreciate it if you could send me a reply at your earliest convenience. 如果您能夠盡早給我回信的話，我將不勝感激。 3．一般情況下介詞后不跟that引導(dǎo)的賓語從句，但except，in，but等可跟that引導(dǎo)的賓語從句。其他介詞后面需要用that從句作賓語時，必須用it作形式賓語。 I know nothing about him except that he lives next door. 我對他一無所知，只知道他住在隔壁。 Yon may depend on it that they will support you. 你相信好了，他們會支持你的。 4．當(dāng)主句的主語是第一人稱單數(shù)時，think，believe，suppose，expect等動詞引導(dǎo)的賓語從句中的否定詞要轉(zhuǎn)移到主句中，即主句的謂語動詞用否定式，從句的謂語動詞用肯定式，這一現(xiàn)象稱為否定轉(zhuǎn)移。 I dont think that your suggestion will work. 我認(rèn)為你的建議行不通。 考點四　表語從句 1．表語從句還可由as if，as though，because等詞引導(dǎo)。 It looks as if we shall stay the night here after all. 看來我們不得不在這里過夜了。 2．當(dāng)主句的主語是reason時，表語從句一般用that而不用because引導(dǎo)，常用句型The reason ... is that ... The reason why he is absent from school is that he is sick. 他沒來上學(xué)的理由是他生病了。 考點五　同位語從句 1．同位語從句常放在fact，news，word(消息)，idea，truth，doubt，belief，thought，problem等詞的后面，對前面的名詞做進(jìn)一步解釋，說明前面名詞的具體含義。引導(dǎo)詞常用that，也可用其他連接詞引導(dǎo)。需注意的是，同位語從句有時不直接跟著它所說明的某個名詞后，而是被別的詞隔開。 We must face the fact that the war has killed many people. 我們必須正視戰(zhàn)爭已經(jīng)奪走了許多人的生命這一事實。 They are faced with the problem whether they should continue the work. 他們面臨著是否應(yīng)該繼續(xù)工作的難題。 Word came that our football team had won the match. 消息傳來，我們的足球隊贏了比賽。 2．同位語從句與定語從句的區(qū)別 同位語從句是對前面的名詞做進(jìn)一步解釋，引導(dǎo)詞只起引導(dǎo)作用，不可省略；定語從句是對前面的名詞進(jìn)行修飾、限制，在句子中作一定的成分。 The news that they had won the game soon spread over the whole school.他們贏得比賽的消息很快傳遍了整個校園。(同位語從句) The news (that) you told me yesterday was really disappointing.你昨天告訴我的那個消息真令人失望。(定語從句) (對應(yīng)學(xué)生用書第263頁) Ⅰ.用適當(dāng)?shù)倪B接詞填空 1．The man didnt know ________ it was that the thief broke into the house and stole all his valuable things. 2．—Have a nice trip! —Thanks.Ill telephone you from ________ I get tomorrow evening. 3．I dont quite understand ________ more women smoke than men in Britain. 4．They are discussing in the meeting room ________ will go to the conference on behalf of the manager. 5．Keep in mind ________ you must respect others first. 6．—Which can I take，Mr.Smith?
