名词性从句包括: 主语从句 表语从句 宾语从句 同位语从句 The question is who can complete the difficult task. He has no idea what a remarkable woman Mary is. That she was able to come made us very happy. He objected that it was impossible. 【注】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。 It depends on the climate whether they are going shopping today. 试试看:新产品销售得好不好取决于它的质量和价格。 (depend on) 形式主语常用结构 It+ be +形容词+ that从句 It is strange that he knows nothing about it. It+ be +名词+ that从句 It is a pity that they have failed in the match. It+动词+宾语+ that从句 It depends on its quality and price whether a new product sells well. It+动词的被动结构+ that从句 It is still unknown which team will win the match. 作文常用句式 It turned out that ... 结果是… It has been proved that ... 已经证明… It is well-known that ... 众所周知… It must be pointed out that ... 必须指出… 三、宾语从句 宾语从句在复合句中作主句的宾语,宾语从 句一般放在动词、介词或形容词后。 She explained that she was late because of the heavy traffic. ④ 在宾语从句中,引导词whether和if基本一样,但介词后的宾语 从句多用whether。 It all depends upon whether we can get their cooperation. ⑤ 动词doubt如用于肯定句,其后的宾语从句常用if/whether引导,如用于否定句或疑问句,则宾语从句用that引导。 I doubt if/whether our football team will win the match. I don’t doubt that I can defeat him in the contest. 引导宾语从句的连接词that通常不能省略的情况: 在动词agree, argue, assure, hold, indicate, maintain, inform, object, suggest等后接宾语从句时,that通常不省略。例如: I assure you that you’re mistaken. He objected that it was impossible. 主句谓语动词后接两个并列的宾语从句时,连接第二个宾语从句的that不可省略。例如: He said he couldn’t tell you right away and that you wouldn’t understand. I know you aren’t a doctor and that you want your son to become a doctor. 宾语从句作介词的宾语: A modem city has been set up in what was a wasteland ten years ago. The shopkeeper did not want to sell for what he thought was not enough. Mary wrote an article on why the team has failed to win the game. 介词后通常不跟由that引导的从句,但可以跟 the fact that从句结构作宾语。例如: He was held responsible for the fact that his dog had bitten his neighbor. He
