doesn‘t而不用isn’t

if it doesn‘t rain 【not rain】 tomorrow,we will go for a picnic为什么用doesn‘t而不用isn’t
If引导的条件从句后面用一般现在时;
rain是动词,前面表否定加助动词,因为是第三人称,所以用doesn't;
如果用isn't ,后面的rain就应该用现在分词raining;但不符合条件从句的语法.

rain 为动词,下雨
不是形容词,故用doesn‘t而不用isn’t

因为rain‘下雨’是实义动词,变否定句时要加助动词,即doesn't (一般现在时)

if 表'如果"时,从句用一般现在时。
rain在这里是动词,表示下雨的意思

rain在这里是动词,表示下雨的意思,动词的否定要用doesn`t.名词或形容词的否定用isn`t

rain本身已经是行为动词,不能再用is,只能用助动词doesn't

rain是动词,如果要加is要加ing了。

rain 在此是行为动词,否定形式必须用doesn't

rain 是动词 下雨
因此其否定形式只能在前面加助动词的三单否定形式前面
如果用 is ,后面就要用raining
