问题补充：

--Who’s singing in the next room? Is it Lucy?

---Itbe her. She has gone to New York.

A. can’t

B. must

C. shouldn’t

D. can

答案：

(答案→)A. can’t

B. must

C. shouldn’t

D. can

解析：根据 She has gone to New York.“她去纽约了。”可知，本句应该是“它不可能是她。”故排除D；“不可能”是can’t。而shouldn’t表示“不应该”，must表示“必须或一定”故与题意不符。所以本题选A。
