Having____exercise every day will do great good to your heal

Having____exercise every day will do great good to your health
A.a great many B.plenty of C.a great deal D.a great number of

B
exercise钱一定要加of 排除A C
a great number of接可数名词复述,排除
而plenty of 绝对是什么都能接（所以一般不用它作为考题选项）
再问： a great many 、.a great deal 跟exercise可以不加the吧？
再答： 是的
再问： 那A.C为什么不行呢？麻烦了.......................
再答： the和of是不一样的呀 a great deal 一定要加of接宾语 a great many一定要加可数名词复数
