辅导班的一道关于情态动词用法的题目:
Her birthday was a week ago, so it _______ (can't / be ) on the 25th.
A. can't be B. can't have been
我不太明白25日是说话之后的日子,还是之前,所以不知道应该用对过去的推测...
he students were dancing to_________ music happily when all of ______ sudden the recorder stopped.A./; a B. the;/ C./;/ D./; the答案为A,如果有一个答案为the; a 是否可以,课本中有短语 dance to the music。dance to the music 与dance to music 有什么区别?谢谢
