Question

—Is Kate coming to the party this evening?
—No, she _________ be at the party. She________ to the UK.

A．mustn't; has gone	B．mustn't; has been
C．can't; has gone	D．can't; has been

Answer 1

C

解析试题分析：句意：凯特今天晚上来参加聚会吗？不，她不可能来参加聚会。她已经去了英国。Mustn’t禁止，不允许；can’t不可能。Been to去过，gone to去了，所以选C。
考点：考查情态动词。
