5. 翻译：你觉得我们去北京度假怎么样?
How do you find...?
=How do you like...?
=What do you think of/about...?
“你觉得/认为...怎么样/好不好?”,用来征求对方意见和看法.
6. D as
翻译：这三条路,我该走哪一条到村庄中去呢?
你愿意走的任意一条.
Any way as you please.
=You can take any way as you please (to take).
语法上的确是理解成：as代替先行词any way做定语从句中take的宾语.但此类句子非常口语化,经常出现省略情况.
如：I can do everything as I like/wish.
=I can do everything as I like/wish (to do).
我可以做任何我喜欢/想要做的任何事情.
