名詞性從句講解練習

1、1名詞性從句一、名詞性從句的連接詞1從屬連詞 that， whether 和 if(1)that ，whether，if 在從句中不充當任何成分，只起到連接從句的功能。that 沒有實際意義，而 whether ，if 意為“是否”。(2)whether 與 if 的用法比較 二者均可作“是否”講，都可以引導名詞性從句，引導賓語從句時可以互換。I don t know whether/if he ll attend the meeting.在下列情況下，常用 whether，不用 if。1whether 引導從句可以放于句首。Whether he comes or not makes no d

2、ifference.2whether 可引導表語從句和同位語從句，if 不可。The question is whether it is worth trying.The question whether he should join the team has not been decided upon.3whether 可以作介詞賓語，if 則不可。I haven t settled the problem of whether I II lend him the money.4whether 后可以加不定式， if 不可。He didn t know whether to get marr

3、ied or to wait.5可以用 whether.or 引導讓步狀語從句，意為“無論，不論”，if 則不可。Whether it rains or snows ， I don t care.2連接代詞弓丨導名詞性從句的連接代詞有： who， whom， whose，what，which，whatever，whichever，whoever。連接代詞在句中既起連接作用，同時又充當主語、賓語、定語、表語等成分。3連接副詞引導名詞性從句的連接副詞有：when, where, how, why。連接副詞在句中既是連接詞，又作狀語。二、 主語從句1主語從句在復合句中充當主語，大多數(shù)主語從句都可以用

7、at I had been away when he called.注意：在It is necessary , important , strange , natural+ that 從句”結(jié)構(gòu)中，從句常用 “(should +)動詞原形”形式。 (2)在 It+ be+ suggested , advised , ordered , requested , insisted , required + that 從句” 結(jié)構(gòu)中,that 從句應用 “ (should )動詞原形 ”。三、 賓語從句1 .動詞的賓語從句(1) 大多數(shù)動詞(hope , tell, say 等)可以帶賓語從句。We

8、 all expect that they will win for members of their team are stronger.置。2I don t think you are right.I don t suppose he cares does he?(2) 動詞 find feel think consider make believe 等后有賓語補足語時 則需要 it 作形式賓語而將 that 賓語從句后I think it necessary that we take plenty of boiled water every day.有些動詞帶賓語從句時習慣上需要在賓語從

9、句前加it。這類動詞(詞組)有 hate, enjoy, like, love, dislike , see to等。I hate it when they talk with their mouths full.2 .一般情況下介詞后只能用wh-類連接詞引導賓語從句。We are talki ng about whether we admit stude nts into our club.注意：(1)where 引導的從句有時也可用作介詞的賓語。We could see the temple quite clearly from where we lived.(2)that 引導的從句作介

11、equest, requirement 等名詞時,表語從句的謂語應用虛擬語氣, 即“ (should+)動詞原形”的形式。His suggestion is that we (should) change our course.2.主語為名詞 reason 時，表語從句中的連接詞要用 that,而不用 why 或becauseThe reason for such a serious accident is that the driver was too careless and drank too much.3.because, as if, as though, as, like 等連接詞

12、也可引導表語從句。He has heart disease.

13、 , who)、連接副詞(when , where, why , how)或whether 引導。I have no idea what has happened to him.3.有時同位語從句不緊跟在它所說明的某個名詞后，而是被別的詞隔開。The story goes that William Tell did kill the king with that sword.六、 名詞性從句的幾個難點1.that 通常不可省略的四種情況：(1) 引導主語從句， that 置于句首時不可省略。That he failed in the exam made his parents disappoi

14、nted.(2) 當一個句子有兩個或多個并列的賓語從句時，引導第二個和以后幾個從句的that 不可省略。I wished (that) we could go sighting in Hangzhou this summer and that we could buy some books on our way back inShanghai.在由 it 作形式賓語，that 引導的賓語從句中，that 也不可省略。He has made it clear that he wouldn t agree to the plan. 引導表語從句和同位語從句時，that 也不可省略。2.what 與

15、 that 的區(qū)別：what 在從句中充當一定成分并且具有特定含義“的人(地方、東西)等”；that 只起引導作用，在主語從句中不充當任何成分并且也沒有含義。What he said was true.That he came late made the teacher angry.名詞性從句強化訓練1. Go and get your coat.
