Why not和Why don't都可以引导疑问句,表示一种建议的意味,它们的区别如下:
一、Why not引导一个疑问句,在这种疑问句中,Why not后面直接跟不带to的动词不定式形式,表示某种建议,如:
Why not do it right now?
Why not try again?
Why not have tea?
Why not have a cup of coffee?
二、Why don't也可以引导一个疑问句,但在Why don't的后面,需要加主语,主语之后再加动词原形,也表示某种建议,如:
Why don't you do it right now?
Why don't you try again?
Why don't you have tea?
Why don't you have a cup of coffee?
