请帮我用英语翻译下这句话

When I was young,my farther died.Once I asked my mother when was her birthday,but she didn't tell me,I had no idea about the reason why she didn't.
总觉得LS那个when is her birthday的时态有问题。。。。（一家之言，o(∩_∩)o...）

“在我很小的时候父亲就去世了，我曾经问过我妈妈的生日是什么时候，但是她都没告诉我，不知道为什么？”

"In my little time on the death of his father, I have asked my mother's birthday is when, but she told me no, I do not know why» "

机器翻译就算了吧... 什么叫 little time？？？？

My father died when I was young,I once ask my mother when her birthday is,but she didn't tell me.Idon't know why.

在我很小的时候父亲就去世了，我曾经问过我妈妈的生日是什么时候，但是她都没告诉我，不知道为什么
