playing basketball is exercise 这句子合乎语法吗exercise 是可数还是不可数名词?
这句话有错误.
应为:playing basketball is an exercise
因为 exercise 是个名词,前面需要冠词,这里应用an

exercise是不可数名词

应该是
playing basketball is an exercise

应该是exercising

Playing basketball is one form of physical exercise. 打篮球是体育活动的一种形式

to exercise

有错误..an exercise..!打篮球是一项运动

Playing basketball is an exercise.
指一项运动时,用an exercise

指笼统的运动是不可数名词 如锻炼
指具体的运动是可数名词 如眼保健操
