当锻炼讲,exercise不可数
但是如果是具体的锻炼,如一节操,一道题,则exercise可数,就可以加s
exercise 一般用法: take exercise, do morning exercises
orning exercises
特殊用法: 表示体育锻炼时不可数;表示练习时可数
do exercise 是不可数名词,表示进行体育锻炼,或锻炼身体
do exercises是可数名词,表示做练习或作习题,比如学习上或优育上或音乐等方面的练习
如:He always does exercise in the morning. 他经常晨练。
He always does some exercises in the morning. 他经常早上作练习(习题)
