1)“am I”的否定形式是“aren’t I”，而不是“am not I”或“amn’t I”。例如： I am right, aren’t I? 2)everything和nothing作为陈述句的主语时是单数，因此反意疑问句中的主语要用 “it”。注意，nothing作为主语时，反意疑问句中的动词要用肯定形式。例如： Nothing is wrong, is it? 3)陈述句中的主语为everyone, everybody, anyone, nobody或no one时，反意疑问句 中的主语用they。注意，nobody和no one是否定词，因此反意疑问句应该用肯定的。例如： Nobody knows it, do they? 4)如果陈述句部分有no, never, hardly, scarcely, rarely, seldom等词，那么，陈述句本身就是否定的，所以要接一个肯定的反意疑问句。例如： He has never been there, has he? 5)如果陈述句中的动词是“wish”,那么反意疑问句中要用“may”。例如： I wish to go there with you, may I? 6)包括听话人在内时“let’s”的反意疑问句要用“shal l we”。反之，反意疑问句中要用“will you”。例如： Let’s go, shall we? Let us go, will you?
