The first exercise should be done in class and the rest _________ at home.这里为什么填 are to be done
The first exercise should be done in class and the rest _________ at home.
这里为什么填 are to be done

The first exercise should be done in class and the rest _________ at home.这里为什么填 are to be done
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 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),do eye exercises(做眼保健操),do English exercises(做英语练习).
在这题当中,exercise 明显是练习题的意思,The first exercise should be done in class and the rest (exercises)___are to be done______ at home.
这里省略了exercises,是复数形式,所以谓语要用复数 are.
