表語從句講解及專項(xiàng)練習(xí)、答案(共5頁)

1、精選優(yōu)質(zhì)文檔-傾情為你奉上表語從句講解及專項(xiàng)練習(xí)概念： 表語從句是在復(fù)合句中作表語的名詞性從句。放在系動(dòng)詞之后,一般結(jié)構(gòu)是“主語+系動(dòng)詞+表語從句”可以接表語從句的連系動(dòng)詞有be, look, remain, seem等。 The trouble is that we are short of money.困難是我們資金短缺。 That is why stone walls are used instead of fences around New England fields.這就是為什么在新英格蘭用石頭墻而不用柵欄的原因。 At that time, it seemed as if I c

2、ouldn't think of the right word anyhow.當(dāng)時(shí),我似乎怎么也想不出一個(gè)恰當(dāng)?shù)淖盅蹃怼Ｒ龑?dǎo)表語從句的詞：從屬連詞that、whether、as though、 as if（That引導(dǎo)表語從句時(shí)，在口語中，間或可以省略。）關(guān)系代詞who, what, which, whom, whose, whatever, whoever, whomever, whichever等；關(guān)系副詞when, where, why, how, however, whenever, wherever等。 由從屬連詞that，whether引導(dǎo)的表語從句。that在引導(dǎo)表語從句

3、時(shí)無詞義，而whether有詞義，意為、“是否”。這時(shí)主句的主語常常是些抽象名詞，如question(問題)，trouble(麻煩)，problem(問題)，result(結(jié)果)，chance(可能性)，suggestion(建議)，idea(想法)，reason(理由)等。表語從句對主句主語進(jìn)行說明、解釋，使主語的內(nèi)容具體化。例如： The trouble is (that) she has lost his money. 麻煩的事是他丟了錢。 The question is whether we need more ice cream.問題是我們是否還需要一些冰淇淋。 The proble

4、m was that it was too valuable for everyday use.問題是它作為日常之用太貴重了。 What she couldnt understand was that fewer and fewer students showed interest in her lessons. 我們不能理解越來越少的學(xué)生對他的課不感興趣。 由關(guān)系代詞引導(dǎo)的表語從句。關(guān)系代詞who, what, which, whom, whose, whatever, whoever, whomever, whichever等引導(dǎo)表語從句，在句中作主語、賓語、表語，關(guān)系代詞不能省略。例如：

5、 The question is which of us should go.問題是我們哪一個(gè)應(yīng)該去。 The problem was who could do the work.問題是誰能做這項(xiàng)工作。 That's what he is worrying about.那就是他在擔(dān)心的事。 That's what we should do.那是我們應(yīng)該做的。由關(guān)系副詞引導(dǎo)的表語從句。關(guān)系副詞 when, where, how, why 除在句子起連接作用外，在從句中還充當(dāng)時(shí)間，地點(diǎn)，方式或原因狀語，本身具有詞義。例如：Go and get your coat. It's

6、 where you left it. 去把雨衣拿來。就在你原來放的地方。 I had neither a raincoat nor an umbrella. Thats why I got wet through. 我們既沒傘也沒雨衣，這是我們淋濕的原因。 That is how mice ruin many stores of grain every year.那就是老鼠是怎樣每年損害大量糧食的。 That is what he is worried about.那就是他所擔(dān)心的。 由連詞because，as if/as though等引導(dǎo)的表語從句。 It looked as if it

7、 was going to snow.看起來好像要下雪了。 That's because we never thought of it.這是因?yàn)槲覀儚奈聪脒^此事。 It seems as if he didnt know the answer.好像他不知道答案。 注意A. 表語從句一定要用陳述語序。False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B. 不可以用if，而用whether 連接表語從句(as if 例外）

8、。引導(dǎo)賓語從句時(shí)可以互換if/whether 位于介詞后要用whether位于句首時(shí)要用whether。引導(dǎo)表語從句，主語從句，同位語從句時(shí)要用whether。False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.C.不像賓語從句，在有表語從句的復(fù)合句中，主句時(shí)態(tài)和從句時(shí)態(tài)可以不一致。Right:

9、 The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D. that在表語從句中不可以省掉。基本用法表語從句只能置于主句之后，而主句的動(dòng)詞只能是聯(lián)系動(dòng)詞。名詞性從句在be等系動(dòng)詞后作表語時(shí)被稱為表語從句例如：The problem is how we can get the things we need.問題是我們怎樣能弄到我們需要的東西。 (how 在表語從句中充當(dāng)方式狀語) The scissors are not what I n
