this is good exercise 为什么不是this is a good exercise ?
那这个exercise意思是“锻炼”了,所以不加a.
exercise主要分两种情况：
1.exercise泛指“锻炼”时,做不可数名词,如：take exercise 锻炼身体 take more exercise多锻炼.
这时候用：this is good exercise.
2.exercise表示“体操”或“练习（题）”时是可数名词,要用复数形式.
如：do morning exercises（做早操）.
这时候要用：
this is a good exercise.
这是一道好的习题.

Exercise(exercis) is (are ) good for our health.Exercise 作为锻炼讲,是不可数名词,后加is 还是are.有exercis这个单词么?如果有,放在这个句子中,需用is还是are. 问题三：如果有exercis 这个单词,那么它和exercise this is a good question1 This love is good for exercis very This is,this is definitely not good 怎么翻译 this dream is too good歌词 This a book is good 怎么改错 this dream is too good中文歌词!
