.)that?It is suggested(requested, proposed, desired, etc.)that?表語從句在句中作表語的從句叫表語從句。引導表語從句的關聯(lián)詞與引導主語從句的關聯(lián)詞大致一樣,表語從句位于連系動詞后,有時用as if引導。其基本結(jié)構(gòu)為:主語 + 系動詞 + that從句。例如: The fact is that we have lost the is why he didn’t e to the looks as if it is going to ,當主語是reason時,表語從句要用that引導而不是because。例如: The reason why he was late was that he missed the train this morning賓語從句:動詞的賓語從句,第五篇:名詞性從句講解名詞性從句講解在復合句中起名詞作用的從句叫做名詞性從句。它包括主語從句、賓語從句、表語從句和同位語從句。歷屆高考試題名詞性從句考查的焦點主要有以下5個方面 語法要點剖析一、名詞性從句主語從句、表語從句、賓語從句、同位語從句,在整個句子中所起的作用,相當于一個名詞。因此,這四種從句通稱為名詞性從句。引導名詞性從句的連接詞可分為三類:連接詞:that, whether, if(不充當從句的任何成分)連接代詞:what, whatever, who, whoever, whom, whose, :when, where, how, why 作句子主語的從句叫主語從句。主語從句通常由從屬連詞that,whether,if和連接代詞what,who,which,whatever,whoever以及連接副詞how,when,where,why等詞引導。that在句中無詞義,只起連接作用;連接代詞和連接副詞在句中既保留自己的疑問含義、又起連接作用,在從句中充當從句的成分。例如: What he wants to tell us is not ,還不清楚。It is known to us how he became a 。Where the English evening will be held has not yet been ,還沒有宣布。有時為避免句子頭重腳輕,常用形式主語it代替主語從句作形式主語放于句首,而把主語從句置于句末。主語從句后的謂語動詞一般用單數(shù)形式。常用句型如下:(1)It + be + 名詞 + that從句(2)It + be + 形容詞 + that從句(3)It + be + 動詞的過去分詞 + that從句(4)It + 不及物動詞 + that從句 It is a pity(a shame, no wonder, etc.)that?It is necessary(important, natural, strange, etc.)that ? It is said(reported, believed, known, etc.)that? It does not matter(seems,appears etc)? 名詞句用作賓語的從句叫賓語從句。引導賓語從句的關聯(lián)詞與引導主語從句表語從句的關聯(lián)詞大致一樣,在句中可以作謂語動詞或介詞及非謂語動詞的賓語。由連接詞that引導賓語從句時,that在句中不擔任任何成分,在口語或非正式的文體中常被省去,但如從句是并列句時,第二個分句前的that不可略,且并列句之間由and連接。He has told me(that)he will go to Shanghai 。He found(that)he lost himself in the forest and that he had no way to dicide the right ,而他又無法確定正確的方向。注意:在demand、order、suggest、insist, desire,等表示要求、命令、建議、等意義的動詞后,賓語從句常用“(should)+ 動詞原形”。I insist that she(should)do her work 。,whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等關聯(lián)詞引導的賓語從句相當于特殊疑問句,應注意句子語序要用陳述語序。I want to know what he has told 。She always thinks of how she can work 。She will give whoever needs help a warm ,她都會給予熱情的支持。,其主語和謂語的順序也不能顛倒,仍保持陳述句語序。此外,whether與if 在作“是否”的意思講時在下列情況下一般只能用whether,不用if:;;;“or not”時;Whether there is life on the moon is an interesting 。Everything depends on whether we have enough 。,當主句動詞是現(xiàn)在時,從句根據(jù)自身的句子情況,而使用 不同時態(tài)。I know(that)he will study English next year.(從句用一般將來時)當主句動詞是過去時態(tài)(could, would除外),從句則要用相應的過去時態(tài),如一般過去時,過去進行時,過去將來時等;當從句表示的是客觀真理,科學原理,自然現(xiàn)象,則從句仍用現(xiàn)在時態(tài)。The teacher told us that Tom had left us for America. Our teacher told us that the earth runs around the sun, believe, imagine, suppose等等動詞引起的否定性賓語從句中,要把上述主句中的動詞變?yōu)榉穸ㄊ?。即將從句中的否定形式移到主句中。We don’t think you are 。I don’t believe he will do 。在句中作表語的從句叫表語從句。引導表語從句的關聯(lián)詞與引導主語從句的關聯(lián)詞大致一樣,表語從句位于連系動詞后,有時用as if引導。其基本結(jié)構(gòu)為:主語 + 系動詞 + that從句。The fact is that we have lost the 。That is why he didn’t e to the 。It looks as if it is going to 。需要注意的,當主語是reason時,表語從句要用that引導而不是because。例如: The reason why he was late was that he missed the train by one minute this morning 同位語從句說明其前面的名詞的具體內(nèi)容。同位語從句通常由that引導,可用于同位語從句的名詞有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如: The news that we won the game is 。I have no idea when he will e back 。同位語從句和定語從句的區(qū)別:that作為關系代詞,可以引導定語從句,充當句子成分,在從句中作賓語時可以省略; that引導同位語從句時,起連詞的作用,沒有實際意義,不充當句子成分,一般不能省略。試比較下面兩個例句:I had no idea that you were here.(that引導同位語從句,不能省略)Have you got the idea(that)this book gives you of life ?(that引導定語從句,作賓語,可以省略)
