——your dress is so nice .___thanks.my mother( )it for me as a birthday present.A has bought B was bought C has bought D will buy 这道题应该是B还是C呢, 对不起,打错了,A应该是bought
选择C不是说瞬间动词不能用现在完成时,而是不能和表示延续一段时间的短语连用如:for... , since, how long 等.瞬间动词也有完成时:My mother has bought it. 但是如果是:How long has she bought it. 或者 She has bought it for three days. 就错了.
