Answer 1

1.Still beginners have to learn from their mistakes, ___they?
A. haven't B. mustn't C. don't D.aren't
C have to的疑问要用助动词
2.Your uncle told me that he overslept.
Oh,my uncle rarely used to oversleep, ___?
A.wasn't he B. was he C. didn't he D.did he
D rarely 否定意，像was这种一定是原句里有才能用，不可能由你加上去，used to do 过去常常做..
3.You have to water the vegetables every day, ___?
A.don't you B. haven't you C. have you D. do you
同第一题

Answer 2

1. 选 C ， have to 是行为动词作谓语，故助动词用 do , 且是“前肯后否”结构
2. 选 D 。 used to 是一般过去时， 是行为动词作谓语， 主动词用did； 句中 rarely 表示“否定意义”， 意为“很少，几乎不怎么”， 所以， 前面是否定结构， 故反义疑问部分要用“肯定疑问式” ， 即 did he。
3. 选择 A 。 have to 在句中是行为动词作谓语，故助动词要用 do , 前面陈述部分用了肯定结构， 故后边要用否定疑问式， 即 don't you .
