解析
试题分析:英语中有些情态动词,通过使用不同的时态形式,可以表示“推测”的含义。1. 情态动词 + 动词原形:must + 动词原形,表示对现在的事实进行非常有把握的推测,一般用于肯定句。如:There must be something wrong. 一定是出了什么差错。may / might / can / could + 动词原形,表示对现在、未来事情发生的可能性的推测。此时, might, could 不表示过去,只是表示推测的语气更加不肯定。一般情况下, may, might 用于肯定句中; can, could 用于否定句、疑问句中。根据语境可知此句的含义是只有Alice弹吉他因此这个吉他一定是她的,表示肯定,故选B。 点评:关于表示推测的情态动词后面所接动词形式,有下列三种情况:若对此刻正在发生的事,接“be +现在分词”;若对现在或未来情况的推测,接动词原形;若对过去情况的推测,接“have +过去分词”。 |
