Question

一道英语单选题
My father ( ) every morning.But he did not take any ( ) yesterday because he was ill
A.exercises;exercise B.exercise;exercises C.exercises;exercises
D.exercise;exercise

Answer 1

选A,两个都是“锻炼”的意思,但前一处是动词单数第三人称,后一个是名词“锻炼”的意思.
区别一下用法：exercise 可以是动词“锻炼”,如 He exercises every day.此时,exercises 是 exercise 的单三形式.
exercise 也可以是名词.
（1）“练习”,“操”可数名词 如 There are many exercises in the book.
We should do eye exercises.
（2）“锻炼”,不可数名词 如 Let's take exercise.
