经典句式

But it is generally agreed，that he，more than anyone else in the history of films，understands the meaning of the word "entertainment"．

但是，人们普遍认为：他比电影史上的其他任何一个人更懂得"娱乐"二字的含义。

(1)句中it is generally agreed，that...意为"人们一致同意......，人们普遍认为......"，it是形式主语，真正的主语是that引导的从句。而且此处的it不可用其他词如this，that等来代替。在英语中，只有it可作形式主语。

(2)与此类似的结构还有：

It is said that...据说......

It is expected that...人们希望......

It is believed that...人们相信......

It is reported that...据报道......

It is proved that...据证实......

It is hoped that...人们希望......

It is suggested that...有人建议......

注意："It is＋过去分词＋that..."这个句型可以与"sb. be＋过去分词＋to do..."之间相互转换。
