6、：My idea is (that) we should do it right away. 我的意見是我們應該馬上干。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詞的不同分為三類： 第一類，用從屬連詞that引導的主語從句，例如： That we shall be late is certain. That the driver could not control his car was obvious. 這種結構主要是對that從句的內容進行強調，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結構，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結構，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結構，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
