1、語法復(fù)習(xí)三：,名詞性從句,語法復(fù)習(xí)三：名詞性從句 名詞性從句相當(dāng)于名詞，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句廳分為主語從句、表語從句、賓語從句和同位從句。 （一）引導(dǎo)名詞性從句的連接詞 1、連接代詞：who, whose, whom, what, which。有詞義，在從句中 擔(dān)任成分，如主語、表語、賓語、或定語等。 2、連接副詞：when, where, why, how。有詞義，在從句中擔(dān)任成 分，作狀語。 3、連接詞：that, whether, if, as if。that 無詞義，在從句中不 擔(dān)任成分，有時可省略；if (whether), as if雖有詞 義，

2、但在從句中不擔(dān)任成分。,注意： 連接代詞與連接副詞在句中不再是疑問句，因而從句中謂語不用疑問式。連接代詞與連接副詞在從句充當(dāng)句子成分，連接詞whether 和if（是否），as if（好象）在從句中不充當(dāng)句子成分，只起連接作用。根據(jù)句義，如果連接代詞與連接副詞，whether、if 和as if都用不上時，才用that作連接詞（that本身無任何含義）。 （二）主語從句 1、主語從句在復(fù)合句作主語。 e.g. Who will go is not important. 2、用it作形式主語，主語從句放在句末。 e.g. It doesnt matter so much whether you

3、will come or not. 3、that引導(dǎo)主語從句時，不能省略。 e.g. That he suddenly fell ill last week made us surprised.,三）表語從句 1、表語從句在復(fù)合句中作表語，位于系動詞之后。 e.g. The question was who could go there. 2、引導(dǎo)表語從句的連接詞that有時可省去。 e.g. My idea is (that) we can get more comrades to help in the work. （四）賓語從句 1、賓語從句在復(fù)合句中作賓語。引導(dǎo)賓語從句的連詞that一

4、般可省略。 e.g. I hope (that) everything is all right. 2、介詞之后的賓語從句，不可用which或if連接，要分別用what或 whether。 e.g. Im interested in whether youve finished the work. Im interested in what youve said.,3、whether與if都可以引導(dǎo)賓語從句，?？苫Q。但下面情況不能互換。 賓語從句是否定句時，只用if，不用whether。 e.g. I wonder if it doesnt rain. 用if 會引起誤解，就要用whethe

5、r。 e.g. Please let me know whether you want to go.（此句如果把 whether改成if，容易當(dāng)成條件句理解） 賓語從句中的whether 與or not直接連用，就不能換成if；不直接連 用，可換。 e.g. I dont know whether or not the report is true. I dont know whether/if the report is true or not. 介詞后的賓語從句要用whether引導(dǎo)。whether 可與不定式連用。 whether也可引導(dǎo)主語從句、表語從句、同位語從句，還可引導(dǎo)讓步 狀語

6、從句，以上均不能換成if。但引導(dǎo)條件從句時，只能用if，而不 能用whether。 e.g. It depends on whether we have enough time. They dont know whether to go there. Please come to see me if you have time.,（五）同位語從句 同位語從句在句中作某一名詞的同位語，一般位于該名詞（如：news, fact, idea, suggestion, promise等）之后，說明該名詞的具體內(nèi)容。 e.g. I have no idea when he will be back. T
