what we should do is to talk about.what ...is to do sth.这句型肯定是对的,后一句我没看到过,也不好说
this subject mainly talks about...肯定对
sb is to do sth./sth.is to be done我都看到过
this subject is mainly to talk about...sth is to do sth应该有这种表达,如果没记错的话,这里是旨在做(相当于aim to),但我没有很大的把握
呵呵this subject is mainly talk about..这definitely是错的
