We        have bought so much food now that Suzie won’t be with us for dinner.
A．may notB．needn’tC．can’tD．mustn’t
B
句意為：既然Suzie不會與我們共進(jìn)晚餐，那么我們沒必要買下這么多的食物。 全句表達(dá)對過去沒必要的事卻做了的一種遺憾。
【考點定位】now that 既然 指明顯的原因；needn’t have done (過去)本沒必要做（卻已經(jīng)做了）may not have done 可能沒做過…… Can’t have done 不可能已做過…… mustn’t have done (原先)一定沒做過……
