高中英语语法内容繁多，又关联甚广，这种情况下及时梳理自己的语法体系很关键。以下是小编整理的关于高中英语语法:it is said that是什么从句的资料，希望对你有所帮助！

it是形式主语，指代后置的主语从句。如果用正常语序that is said，其实就是 “one says＋that引导的宾语从句” 的被动语态，未免主语部分太长，显得结构臃肿，所以就改用 it is said that句式。

it is said that是据说，据传言的意思

过去式，it was said that + 句子，【谓语用过去时】

将来时，it will be said that +句子【谓语用将来时】
