一、主语从句的概念与类型 主语从句在复合句中作主句的主语,引导主语从句的词有从属连词that, whether以及连接代词who, what, which, whoever, whatever, whichever和连接副词when, where, why, how等. 例如: That she was chosen made us very happy. 她当选了使我们很高兴. What caused the accident is a complete mystery. 是什么导致了这次事故还完全是一个谜. Whether she will come or not is still a question. 她是否来还是一个问题. Which team will win the match is still unknown. 哪个队会赢得这场比赛还不知道. Whoever comes to the party will receive a present. 参加聚会的每一个人都将收到一份礼物. When they will start has not been decided yet. 他们何时出发还没决定. 注意:上述例句中的主语从句都是放在句首,但有时为了使句子结构平衡,避免"头重脚轻",常用it作形式主语,而把从句放在后面. 例如: It is a pity that she has made such a mistake. 她犯了这样一个错误,真是遗憾. It depends on the climate whether they are going shopping today. 他们是否今天去购物还得看天气情况. 这样就构成了下面一些常用句型: 1)It is + adj. / n. +从句 It is a pity/shame that...遗憾的是…… It is possible that...很可能…… (责任编辑：admin) |
