weather is! 转为陈述句时为: The weather is hot这时句子的开始单词为 the weather, 再来看感叹句在 the weather 前只有形容词,所以应用 how。至于是用 what a 还是 what 要看名词的具体情况而定,单数可数名词加 what a 其余的加用 what。
[误] We have to sing this, have we?
[误] We have to sing this, haven't we?

[析] 在反意疑问句中除了标准的一些常规外,有一些例外: Let's go home, shall we? Let us go home, will you? She had to leave, didn't she?
