571　Why not和Why don't能否換用

　Why not 和 Why don't 都表示“為什么不，為何不”，表示建議或責(zé)備，但結(jié)構(gòu)不同：

Why not+動(dòng)詞原形

Why don't +主語(yǔ)+謂語(yǔ)動(dòng)詞 （為特殊疑問(wèn)句 ）

Why not take a good rest in the shade? 是否應(yīng)在樹(shù)蔭下好好休息一下呢？

Why not have a drink? 為什么不喝一杯呢？

Why don't you look it up in the dictionary? 你為什么不查一下字典呢？

Why not try again? 為什么不再試一下呢 ?

Why don't you try again?

Why not do like that? 為什么不那樣做呢 ?

Why don't you do like that?

Why not ask him? 為什么不問(wèn)他呢 ?

Why don't you ask him?

提示

表示建議也可用what about +名詞或動(dòng)名詞，how about +名詞或動(dòng)名詞，參見(jiàn)有關(guān)部分。
