exercise单复数辨析（中考，高考）
You should do more______. Don't always sit at the desk busy doing your ______.
A. exercise; exercises
B. exercises; exercise
C. exercises; exercises
D. exercise; exercise

(1) 表示重复性动作时，为可数名词，对应含义为“练习题、早操、操练”，如do morning exercises（做早操）, do some English exercies（做英语练习题）
(2)表示抽象笼统的含义，为不可数名词， 对应含义为“锻炼”，A bit more exercise would do you good. 多些锻炼将对你有好处。
