it作形式主语和作形式宾语的区别
如：I find it necessary to take exercise every day.
I find it's necessary to take exercise every day.
I find that is necessary to take exercise every day.
这三句语法对吗?
it作形式主语和作形式宾语有什么区别呢?
老师讲宾语从句时说that可以做从句的主语

英语专业回答：三句都对.解析:第一句中的it是做宾语,第二句中的it是做形式主语,原句等于I find （that）it's necessary to take exercise every day.that可以省略,第三句也是正确的,原句等于I find （that）that is necessary to take exercise every day.that可以省略,第三句和第二句是一样的.it做形式主语,真正的主语是后面的不定式,it做形式宾语和正常的宾语一样,用在动词后面!
