Question

you can't have him go to the party with you. he has __ things to do

A many B a good many
答案是B 如何解释不选择A 呢

Answer 1

a good many 是指相当大的量，比many所指的量大，也有强调的意思。
a good many：a fairly large number
many many/a great many: a very large number

另一点，既然是考试，应该是考比较高级的用语，a good many 比many 更适合做考点，用起来也更高级些。a good many, 也可用so many.

Answer 2

主要是看题意。

many，很多的。
a good many 非常多的。

两者程度不一样。根据题意，需要选B。

希望能帮到你。
