第一時間為你提供正確答案：
因為第一個句子是現在完成時,主語復數they,所以用haven't you.
而第地個句子是一般現在時,主語三單,所以用doesn't he.
You must go home, needn't you? 為什么不能用mustn't you?呢語法就是這樣規(guī)定的There is no use to do/doing?
It is no use to do/doing?
It is useless to do/doing?
這些到底是to do 還是doing?第三個有這個說法？
They have stayed here for a few days,haven't you?為什么不能用 don't you?而Jane has to stay here all day,doesn't he?為什么不能用hasn't
They have stayed here for a few days,haven't you?為什么不能用 don't you?而Jane has to stay here all day,doesn't he?為什么不能用hasn't he?老師說那是因為has 沒有擁有的意思 那第一句的理由呢?
