---Could I have some snacks between meals, mum?
---No, you __________.
A．couldn’tB．shouldn’tC．can’tD．might not
C

試題分析：can能，能夠。Could是can的過去式，用于一般現(xiàn)在時態(tài)表示委婉的請求建議等語氣。couldn't 是can`t的過去式和虛擬式。在實際應(yīng)用中，could`t是can`t的禮貌用法，含有不情愿的意思，加上有虛擬的含義，語氣較弱。表示否定時can't比couldn't的否定意味更重。shouldn’t不應(yīng)該； might not可能不。句意：我能在兩餐之間吃一些小食品嗎？媽媽。不，你不能。結(jié)合語境可知選C。
點評：情態(tài)動詞的考查是初中英語考查的重點，平時學(xué)習(xí)中一定要熟記這些詞的基本詞義及用法上的不同，注意其用法及在句子中表達(dá)語氣的不同�？荚囍薪Y(jié)合語境選擇合適答案。
