三个句型后都跟that从句,都是主语从句,it是形式主语,真正的主语是后面的that从句.现分述如下:
1.It is said +that从句,意思是“据说。。。,听说。。。”。如:It is said that Liu Dong did well in the final exam.(听说刘东期考考得好)
2.It is believed +that从句,表示一种众所周知的事实,意思是“人们相信。。。,我们相信。。。”。如: It is believed that China is the biggest country in the world in terms of population.(人们相信,中国是世界上人口最多的国家)
3. It is true +that从句,阐述一种客观事实,意思是“。。。是真的,我们知道,。。。”。如:It is true that the earth travels around the sun.(我们知道,地球是围着太阳转动的。)
