《牛津英语语法》中的一个时态错误
在牛津英语语法（PEU第四版）的第31章，讲到词汇bathe的时候，作者给出了一个例句：
I always bathe before I got to bed.
请教老师，before从句用了一般过去时，主句的时态应该也是过去的某种时态吧，不管怎样，也不应该用一般现在时吧。因为是外研社出的书，印刷体还特别用红体字标识了“bathe”，所以拿不定主意，我试着改成一下几句，请老师帮助评判正误：
（过去时态）
1. I always bathed before I got to bed.
2.I had always bathed before I got to bed.
3.I always bathed before I had got to bed.
3.I would always bathe before I got to bed.
（现在及将来时态）
4.I always bathe before I get to bed.
5.I have always bathed before I get to bed.
6.I always bathe before I have got to bed.
6.I will always bathe before I get to bed.
