问题补充：

—I saw Kate in the park this morning.

—It her. She moved to Canada last week.

A. can be

B. must be

C. can’t be

D. mustn’t be

答案：

A. can be

B. must be

(答案→)C. can’t be

D. mustn’t be

解析：can be 可能是；must be一定是；can’t be不可能是；mustn’t be禁止，不许。句意：今天上午我在公园看见凯特了。根据下文，她上周移居到加拿大了。可知前文指的是，不可能是她。故选Ｄ。
