1.当陈述句的主语为表示人的代词：anybody,anyone,everybody,everyone,somebody,someone,nobody,no one,these,those时,反意疑问句的主语用they.例如：Everybody knows what I said,don’t they?Nobody says a word a...nobody作主语是不是要看成否定，Nobody says a word about the incident, don’t they?应该为 Nobody says a word about the incident, do they?是的，刚才是笔误。很抱歉。
