cats eating mice is interesting 有语法错误吗

花素儿是错的。
Cats eat mice is interesting.也是不对的。因为主语的先行词在宾语从句中不能省略。
It is interesting that cats eat mice . 是对的。但如果你不要改变语序，你可以用Cats' eating mice is interesting.

可以用It is interesting that cats eat mice .

错误。！如果是cats eating mice is interesting就没有谓语了。

Cats eat mice is interesting. 是正确的。
Cats eat mice 是主语从句。没问题

错误的
