I don't imagine that he will come here if it rains,____.

a.will he b.won't he
答案是a，为什么不选b？

是a没错
在有imagine think believe这类词引导得从句中要否定芹氏亩转移，就是说don't imagine 实际上是“I imagine that he will not come here if it rains.”核芦
所以反意疑嫌森问句要用肯定式
这回懂了吧

这滑册里宽差实际上慎让皮是"I imagine that he won"t come here if it rains,____."
但是否定前置.
所以选A

这个句子的意思是我认谈链早为如果下雨了他不会来，不是唤戚吗？

类似I don't think/image等等，进含雀行反问时都是以这种形式反问。
eg. I don't think he will win the game,will he?

---

这是反义疑问句，自然是will he

---

否定在主句上
