---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(guò)去式,用于一般現(xiàn)在時(shí)態(tài)表示委婉的請(qǐng)求建議等語(yǔ)氣。couldn't 是can`t的過(guò)去式和虛擬式。在實(shí)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(yǔ)氣較弱。表示否定時(shí)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(yǔ)境可知選C。
點(diǎn)評(píng):情態(tài)動(dòng)詞的考查是初中英語(yǔ)考查的重點(diǎn),平時(shí)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(yǔ)氣的不同。考試中結(jié)合語(yǔ)境選擇合適答案。
