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

解析試題分析：句意：凱特今天晚上來參加聚會嗎？不，她不可能來參加聚會。她已經去了英國。Mustn’t禁止，不允許；can’t不可能。Been to去過，gone to去了，所以選C。
考點：考查情態動詞。
