请教一道英语练习题Being a public holiday,the beach was crowded with people.怎么改成正确的带有分词从句的句子?
It being a public holiday,the beach was crowded with people.
这里的It是逻辑主语,必须要加上,否则与the beach is a public holiday是不通的.
这是非谓语动词中的一个用法：主句的主语与非谓语动词无法构成主谓或动宾这样的逻辑关系时,需要特别加上非谓语动词的逻辑主语,构成独立主格结构.

本来句子就是对的，比如

1. The teacher who teaches English in our school is very attractive.

2. The teacher teaching English in our school is very attractive.

第二句就是分词从句

AS A PUBLC HOLIDAY,the beach was crowded with people
