There's not much to do here ____

[A] in Sundays
[B] on Sundays

这题应该选择什么？
我记得in是泛指，按我的理解。。反正是泛指没特指是那个星期日
，只是泛泛指每个星期日。是不是in也可以呢？

这里我不太清楚应该用in还是on。。。

用例子总是会很直观，请看：
我出生在纽约。I was born in New York. (born + in + 出身地)
我出生在1984年。 I was born in 1984. (born + in + 年份)
我出生在1984年9月。I was born in 1984，Sept. (born + in + 年月)
我出生在1984年9月9日。I was born on Sept. 9th,1984.
(born + on+ 年月日)
我出生在一个雨天。I was born on a rainy day. (born + on+ 特殊日子）
在具体的日期或时间要用ON。

记住:凡在某天都用on.
on July 1st,
on Sunday,
甚至on Sunday morning
