　　幾個情態(tài)動詞常考的句型

　　(1)may/might (just) as well“不妨，最好”，與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，怎么也不過分”。注意這個句型的變體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為used to (do)的否定式。

　　(4)should 除了“應(yīng)該”一層意思外，大綱還規(guī)定要掌握其“竟然”的意思。如：I didn’t expect that he should have behaved like that.
