【题目】He plays basketball very well. He_________ it a lot.
A.may practiseB.must practise
C.must have practisedD.should have practiced
在线课程【答案】C
【解析】
考查情态动词+have done的用法。句意：他篮球打得很好。他一定经常练习。根据He plays basketball very well.可知，此处是对过去行为的肯定推测，应使用must have done，意为“他过去一定经常练习”。 should have done sth.意为“应该做某事，而实际上没有做”，明显不符合语境。故选C。
