There's possibility/hope/no doubt.那么It's开头的后面可以跟什么?

首先要知道这是两个句式。1。there is + 抽象名词 + to do sth。有。。。做某事。There is no need to tell him he truth。2 A。it's+抽象名词/形容词 +(for sb。) to do sth。做某事是。。。如:It is useless to stop him。It is a duty for him to help others。B。it's + 名词+ doing sth。做某事是。。。如; It is no use/good telling him the news。3。it is +。。。可以构成很多句式不能一一列举,抱歉!
