语法 Grammar in use
否定疑问句
否定疑问句可以表示说话者惊异的情绪、责难的口吻或赞叹；也可表示说话者的某种建议、邀请、请求或看法等。请看下列疑问句的简略否定式：
(be:) Aren't you a student? 难道你不是学生吗？
Isn't it hot here? 这里难道不热吗？
(can:) Can't you wait a moment? 你不能等一会儿吗？
(have:) Haven't I asked you? 难道我没问过你吗？
(do:) Don't you want to stay with us? 你难道不愿意与我们呆在一起吗？
(did:) Didn't you see him yesterday? 难道你昨天没看见他吗？
回答这种问题时用简略回答。如果答语是肯定的，就用 Yes；如果答语是否定的，就用No。不过，这种答语的汉语译法有特殊之处。
一般否定疑问句有完全式和简略式之分，它们的词序是不同的。
完全式：Is she not a nurse? 她不是一位护士吗？（简略式：Isn't she a nurse? 她不是一位护士吗？）
