英语语法长难句与必背英语句型 英语长难句分析之基础语法 名词性从句之名词性从句 主语从句可以按其引导词的不同分为三类: 第一类,用从属连词that 引导的主语从句,例如: That we shall be late is certain. That the driver could not control his car was obvious. 这种结构主要是对that 从句的内容进行强调,属正式文体,连词 that 不可以省略;但是在一般情况下,往往使用先行it 结构,即用it 作形式主语,而把that 从句放到后面,这时,在口语中,连词that 有时 则可以省略.所以上述两句可以改为: It is certain that we shall be late. It was obvious that the driver could not control his car. 如果整个句子是疑问形式,就只能用先行it 结构,例如: Is it true that he would take the risk? Is it possible that they will come tomorrow?
