the week before 和before this week的区别?各用在什么时态里?

the week before 过去的一周,用过去时(有时也用现在完成时)
before this week 在这周之前,这句意思不明,我觉得应该是before the end of this week或者before this weekend,用将来时.是这样一道题目,请帮我讲解一下哦,急急急
he told me that he had written a letter to his father___
A the last week B befor this week
cthe week before D the next week选C
前一周
A是最后一周B是要用于当前所说的,但是是引用语是过去,所以排除
D是下一周,根据句意已经完成,是前一周引语是过去的过去吧?非常感谢,我会及时采用您的答案是的,用的过去完成时
