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

C

【解析】

试题分析：句意:今晚凯特要来参加聚会吗？不，她不可能参加。她去了英国了。mustn't一定不要，不许，表禁止；has been to去过……；can't不可能，表推测; has gone  to去了……（还没回来）。根据题意她去了英国还没回来，所以推测出她不可能来参加聚会。故选C。

考点：考查情态动词和现在完成时态。
