(完整版)表語從句用法

1、表語從用法1. 定義：用作表語的從句叫做表語從句2. 引導表語的從句的關聯(lián)詞的種類( 1)從屬連詞 that. The trouble is that I have lost his address.The reason was that he was late for school.(2) 從屬連詞 whether, as, as ifHe looked just as he had lookedten years before.The question is whether they will be able to help us.注：從屬連詞 if 一般不用來引導表語從句，但 as if

2、 卻可引導表語從句。All this was over twenty years ago, but it' as if it was only yesterday.The key is whether we can solve the problem.It looked as if it was going to rain.注：能跟表語從句的謂語動詞一般為系動詞be, seem, look, sou nc等He looked just as he had looked ten years before.It sounds as if someone is knocking at the

3、 door.(3) 連接代詞 who, whom, whose, what, which, whoever, whatever, whichever 在表語從句中做主語、賓語等。The problem is who we can get to replace her.That was what she did this morning on reaching the agreement.My question is who left.(4) 連接副詞 where, when, how, whyWhat I wonder is when he left. This is where they o

4、nce lived.That is why he didn't come here.The question is how he did it.（5）連詞 because 可引導表語從句。注意： because 可引導表語從句， 但與之同義的since, as, for等不用于引導表語從句。I think it is because you are doing too much.It's just because he does'ntknow her.That' because he did'understand me.（Tha' because

5、 強調(diào)原因）That's why he got angry with me.（Thafswhy強調(diào)結(jié)果） 注意：在一些表示“建議，勸說，命令”的名詞后面的表語從句中， 謂語動詞用虛擬語氣.Should+動詞原形表示，should可省略。My suggestion is that we （should） start early tomorrow.一堅持（in sisit）二命令（comma nd, order）三建議（suggest, advise, propose） 四要求（desire, dema nd, require, request 四注意事項（重點看）1. 表語從句要用陳述語

6、序。That is where the famous scientist was born.This is why she is so happy today.2. that和what在引導的表語從句that 本身沒有詞義，在句中只起連接作用，不充當句子成分； what 則表示“所的（人或事）”在表語從句中充當主語或賓語等。That facet is that more than seventy percent of the earth's surface is covered by water.What he told you was what had been discussed

7、at the meeting.3. if 與 whether 均意為“是否”引導的表語從句是，只能用 whether，不能用 if 。 The question is whether we can finish our work by tomorrow evening.4. 語氣(1) 主語為 advice, order, idea, notion, proposal, suggestion, requeS等 一些表示“建議，勸說，命令”的名詞，之后的表語從句中， 謂語動詞用虛擬語氣。Should+動詞原形表示，should可省略。My suggestion is that we (shoul

8、d) start early tomorrow.Our only request is that this should be settled as soon as possible.(2) as if / though 引導的表語從句時， 從句謂語多用虛擬語氣。 這是因 為從句中的情況與事實不相符。具體來說，如果從句表示與現(xiàn)在事實相反，謂語動詞用一般過去式；如果從句表示與過去事實相反，謂語動詞“had+d on£如果從句表示將來的可能性不大，用 would(might, could)+動詞原形。Li Lei is now in a new jacket he looks as if

9、 he were an American boy. The girl is giving us a vivid description of the moon.It seems as if she had been to the moon many times.但是，如果as if, as though引導的表語從句所表示的與事實相符，從 句則用陳述語氣。The clouds are gathering. It looks as if it is going to rain.5. 時態(tài) 不像賓語從句，在有表語從句的復合句中，主語時態(tài)和從 句時態(tài)可以不一致。The question is who

10、 will travel with me to Beijing tomorrow.The question is why he cried yesterday.系動詞分類：一 根據(jù)系動詞后所跟結(jié)構(gòu)，我們可以把英語系動詞分為兩大類：完全系動詞（其后只能跟表語動詞，如 be, seen）和半 系動詞（其后既跟表語作系動詞用法， 也可以跟賓語或狀語 作實義動詞用，如 look ）1）He looked sadly at the boy. 看（ 著，實義動詞用法 ）He looks a clever boy. （看起來，系動詞用法 ）2）He looks at a clever boy.看著，實義動詞
