have you drink some

have you drink some
have you drink some

have you drink some
如果drink是一般式的时候,那这句话的意思就是,让你喝你一些水.（有点强迫和不礼貌的感觉）
如果drink是完成时（drunk）的话,这句的意思就是,你喝过水了吗?（出于关心问的.）

对，have sb do sth意思与let sb do sth相同，让某人做……

have you drunk some water
你喝过水吗

have you drink some water 让你喝点儿水
Have you drunk some water ? 你喝过水没？

Have sb do sth: have是使役动词,后接省略to的不定式; 表示“让某人做某事”。
have you drink some water 意为：让你喝点水

就是请你喝水的意思
