If he enjoys concerts,why doesn't he come with us?为什么用 doesn't 用won't
不能用won't,if引导条件状语从句时,从句一般时,主句一般将来时,是通常的情况.句意为“如果他喜欢演唱会,为什么他不和我们来?”所陈述的是既定事实,他就是没来.用won't在逻辑上不合适.
再问： 谢谢你的回答 但是并不是所有的if语句都用主将从现啊，如果句意为“如果他喜欢音乐会，为什么不会和我们一起来？”也符合逻辑啊。
再答： why don't you的结构属于提建议的句型，并不表示疑问，这句话其实和if的关系不大。而且不知道这句话出自哪，一般建议都是why don't you do ...或者Why don't we do .. 第三人称建议的很少见
