---, darling. I haven never thought about it.
A. Take your time
B. You’ve got me there
C. Don’t be silly
D. Bad luck
答案：
A. Take your time
(答案→)B. You’ve got me there
C. Don’t be silly
D. Bad luck
解析：句意为：----爸爸，你能告诉我为什么这么多的学生在这么小的年纪就去国外学习呢？ ----太可惜了，我从来没想过这个问题。Take your time放松点儿；You’ve got me there 你把我难倒了（你难倒了我）；Don’t be silly 别傻了；Bad luck运气不佳。故答案应为B
