英语句子成分划分There are so many people in the hall that it's hard for me to find him

Answer 1

从语法上讲，这是一个倒装句。
主语是so many people, 谓语是are, in the hall 是地点状语。因为这是一个“哪里有什么”的句型，因此，句子的开头要使用there, 作为引导。在这个长长的句子中还有一个句型，即; so...that “如此...以至于”， 其中that it's hard for me to find him 是一个结果状语从句。全句的意思是：
礼堂里有如此多的人以至于我很难找到他。

There are 形式主语
so many people 真正主语
in the hall 地点状语
that 引导结果状语从句
it's 形式主语
hard for me 宾语
