Sam is very active and does exercises every day.这句话哪个地方出错了?

Sam is very active and exercises every day.作锻炼讲EXERCISE就是动词,不用DO EXERCISE了

exercises应为单数,这里不可数

1.改正:exercises → exercise.
2.固定短语do exercise意思是“锻炼”,其中的exercise是不可数名词.
而do exercises意思是“做练习题”.
3.如果是“做早操”则为:do morning exercises;
“做眼保健操”是do eye exercises.
