It 作形式主语和it引导强调句的比较
而强调句则不同，它的结构是： It+be+被强调部分+that+从句
强调主语：It is the times that produce their heroes. (时势造英雄) 强调宾语：It is English that Prof.Lin teaches us. 强调状语：It was in shanghai that I saw the film. 判断是否是强调句有一个方法，就是将that以后的“句 子的其余部分”拿出来单独看，看有没有缺成分，缺的 是什么成分，再把谓语动词后面that前面的那部分，带 到你认为缺成分的地方，如果放进去是一句完整的句子 了，那就说明是强调句。
It 作形式主语和it引导强调句的比较
为避免头重脚轻，常以形式主语 it引导从句。 It+形式主语谓语+从句。
例：It is known that... It is shown that... 用it 作形式主语的结构 (1) It is +名词+that从句 It is a fact that … 事实是…… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is +形容词+that从句 It is natural that… 很自然…… It is strange that… 奇怪的是…… (3) it +不及物动词+that从句 It seems that… 似乎…… It happened that… 碰巧…… (4) it is+过去分词+that从句 It is reported that… 据报道…… It has been proved that… 已证实……
