表語從句注意事項(xiàng)

1、一、表語從句的引導(dǎo)詞引導(dǎo)表語從句的詞有連詞that, whether，連接代詞和連接副詞，關(guān)系代詞型what，以及as if, as though, because等連詞。1. 由that引導(dǎo)The fact is that he doesnt really try. 事實(shí)是他沒有做真正的努力。The trouble is that I have lost his address. 麻煩的是我把他的地址丟了。My suggestion is that we should tell him. 我的建議是我們應(yīng)該告訴他。His sole requirement was (is) that the

2、system work. 他唯一的要求是這個制度能起作用。My idea is that we should start making preparations right now. 我的意見是我們馬上就開始做準(zhǔn)備工作。2. 由whether引導(dǎo)The question is whether the film is worth seeing. 問題是這部電影是否值得看。【注意】whether 可引導(dǎo)表語從句，但與之同義的if卻通常不用于引導(dǎo)表語從句。3. 由連接代詞引導(dǎo)You are not who I thought you were. 你已不是我過去所想像的人。The problem is

3、 who we can get to replace her. 問題是我們能找到誰去替換她呢。The question is who (m) we should trust. 問題是我們應(yīng)當(dāng)相信誰。What I want to know is which road we should take. 我想知道的是我們應(yīng)走哪條路。4. 由連接副詞引導(dǎo)The problem is how we can find him. 問題是我們?nèi)绾握业剿?。That was when I was fifteen. 這是我15歲時發(fā)生的事。Thats where I first met her. 那就是我第一次遇見她

4、的地方。Thats why he didnt come. 這就是他沒有來的緣故。Thats why I object to the plan. 這就是我反對這個計(jì)劃的原因。Thats where you are wrong. 這就是你不對的地方。5. 由關(guān)系代詞型what引導(dǎo)Thats what I want to stress. 這是我想強(qiáng)調(diào)的。Thats what we are here for. 我們來這里就為了這個。Fame and personal gain is what theyre after. 他們追求的是名利。He is no longer what he was. 他已經(jīng)

5、不是以前的他了。6. 由as if / as though引導(dǎo)It isnt as if you were going away for ever. 又不是你離開不回來了。Now it was as though she had known Millie for years. 現(xiàn)在好像她認(rèn)識米莉已有好多年了似的。It is not as though we were poor. 又不是我們家里窮。 【注意】because 可引導(dǎo)表語從句，但與之同義的since, as, for等也不用于引導(dǎo)表語從句。二、連詞that的省略問題引導(dǎo)表語從句的that通常不省略，但在口語或非正式文體中有時也可省略

6、：My idea is (that) we should do it right away. 我的意見是我們應(yīng)該馬上干。The trouble is (that) he is ill. 糟糕的是他病。主語從句主語從句可以按其引導(dǎo)詞的不同分為三類： 第一類，用從屬連詞that引導(dǎo)的主語從句，例如： That we shall be late is certain. That the driver could not control his car was obvious. 這種結(jié)構(gòu)主要是對that從句的內(nèi)容進(jìn)行強(qiáng)調(diào)，屬正式文體，連詞that不可以省略；但是在一般情況下，往往使用先行it結(jié)構(gòu)，即用

7、it作形式主語，而把that從句放到后面，這時，在口語中，連詞that有時則可以省略。所以上述兩句可以改為： It is certain that we shall be late. It was obvious that the driver could not control his car. 如果整個句子是疑問形式，就只能用先行it結(jié)構(gòu)，例如： Is it true that he would take the risk？ Is it possible that they will come tomorrow？ 常使用先行it結(jié)構(gòu)，用that從句作主語的句子有下列幾個句型： 1、It +

8、 be + 形容詞 + that從句： It is clear that he was telling the truth. Its probable that well be a little late. 2、It + be + 名詞詞組 + that從句： Its a pity that you cant go with us. 3、It + 及物動詞 + 賓語 + that從句： It worried her a bit that her hair was turning grey. It shocked me that Peter didnt tell anybody where he was. 4、It + be + 過去分詞 + that從句： It is sa
