    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
    句意为：既然Suzie不会与我们共进晚餐，那么我们没必要买下这么多的食物。 全句表达对过去没必要的事却做了的一种遗憾。
    【考点定位】now that 既然 指明显的原因；needn’t have done (过去)本没必要做（却已经做了）may not have done 可能没做过…… Can’t have done 不可能已做过…… mustn’t have done (原先)一定没做过……
