A woman answered, but I didnt recognize her voice.Oh, it _ my aunt Jean.A. must beB. must have beenC. might beD. can have been剖析：对过去情况的肯定推测，宜用“情态动词 + 动词完成式”，再根据句意，可确定答案为B。注：can 表示推测通常不用于肯定句。答案：B（4） Is there a flight to London this evening?There _ be. Ill phone the airport and find it out.A. mustB. mightC. wouldD. can剖析：根据下文的 Ill phone the airport and find it out 可知，说话人对自己的推测没有很大把握，故选 might。若选A，语气太强，不合语境；若选D，不合语法习惯，因为can 表推测通常不用于肯定陈述句中。答案：B（5）When can I come for the photos?
