题目内容：

they didn't tell me where they will go for their holiday. ?
1.they didn't tell me where they will go for their holiday.
2.they didn't tell me where they would go for their holiday.
第一句和第二句只是will换成了would.为什么这里只能用would,而不能用will? 我以为用will好象也可以呀!
这是一个选择题里面的答案,我不明白,请行家指点.

很简单的,they didn't tell me是过去时,定语从句中当然也是过去时.
would是will的过去时
