I think ___ (it) necessary for students to make an interest in all subjects .
问题描述:
I think ___ (it) necessary for students to make an interest in all subjects .
这里是不是有两个答案?1.it(作形式主语)2.It's(it作形式宾语)
答
恩,这两个答案都是可行的,但是句子结构就完全不同了
如果是用it,作形式主语
而用it's之后,后面就是一个宾语从句了
I think (that) it's necessary for students to make an interest in all subjects
it还是作后面宾语从句的形式主语
