3.几个情态动词常考的句型
    (1)may/might (just) as well“不妨，最好”，与had better相近。如：
    Since the flight was cancelled, you might as well go by train.
    (2)cannot/can’t…too… “越……越好，怎么也不过分”。注意这个句型的变体cannot…over…。如：
    You cannot be too careful when you drive a car.
    The final chapter covers organizational change and development. This subject cannot be overemphasized.
    (3)usedn’t或didn’t use to为used to (do)的否定式。
    (4)should 除了“应该”一层意思外，考研大纲还规定要掌握其“竟然”的意思。如：
    I didn’t expect that he should have behaved like that.
