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.
