@仇珠6018:it作形式宾语——find/think/belive+形容词/名词/for sb.+to do sth. -
郎码13228289265…… 很简单.我来告诉你. 1 I think that it is necessary to do exercises.---------这是宾语从句,that是宾语从句的连接词,think是主句的谓语动词.that后面的是从句部分. 2 we all think it necessary to do exercises.---------这是简单句,其中: we all(主语) think (谓语)it(形式宾语) necessary(宾语补足语) to do exercises(真正主语) 3 find/think/believe一般都是这样行为的. 现在你明白了吗?
