用doesn't吗?能不能讲解一下啊?

应该是dosen't~
rain在这里作动词
又it是单数,所以用doesn't

rain这里是名词,雨天,所以用ISN‘T

We will have a picnic if it doesn't rain tomorrow.
或者 We will have a picnic if it ISN'T rainny tomorrow.

be rainy
rains(does rain)
是答案错了

【rain】n.雨, 下雨, 雨天 vi.下雨
“rain”作名词确实是可以的,但应该有冠词吧?它是可数的!还是用doesn't才对,要不然就要加冠词!

rain作为动词,助动词应该用do,第三人称单数,则用doesn,t
