-–Mary knows the city quite well.
--She______ well have been there before.
A.needB.couldC.should D.may
D

试题分析:考查情态动词:A. need 需要B. could 能够C. should应该D. may可以,几个选项只有may可以用may well do sth的意思是“有足够/充分的理由去做某事”。 句意:玛丽很了解这个城市。--她很有可能去过那里。选D。
点评:情态动词要记住基本含义,还有情态动词的多种含义,象could表示:能够,也可以表示客观上有可能。May还可以构成词组:may as well do sth不妨做…,may well“有足够/充分的理由去做某事”,如: You may well not accept his apology.你有足够/充分的理由不接受他的道歉。
