问题描述：
73.Tom ___ the party as no one saw him there yesterday evening
A.can't attend
B.mustn't attend
C.won't have attended
D.couldn't have attend
请说下考点及解题思路,其他答案为什么不行?
答
严格地说本句无正确答案，首先是对过去的推测，选项A表示“不能参加”显然错误，选项B中mustn't表示“禁止”，若用he作主语，则应为mustn't be attend,C项为将来完成时，显然不合题意，D项错误，应为couldn't have attended则本句正确。
答
C won't have attended (无意参加)
.首先是对过去的推测，排除A, B
如果是 D, 则应是 couldn't have attended (attend要用过去分词)
唯一正确的是 C.
答
D
这是情态动词加完成时表示对过去的推测
首先是对过去的推测,排除AB,表推测是没有mustn't的用法的
tom（昨天）不可能在宴会上,因为昨天晚上没人看到他在那里
答
C won't have attended (无意参加)
.首先是对过去的推测，排除A, B
