“有多远走多远”英语怎么说？如何用英语说这句话？这是旅游卫视的广告语，请翻译得漂亮，诗意一些。

先回答第二题
as far as , as long as 这里都是等同于 if only, on condition that
中文有时候就都译为“只要”!
其实这两句话实际上说的就是 if possible:
I'll help you as possible as I can. I'll do my best to help you.
We’ll help you as possible as it can be.
于是as far as 就是一个连接词而已.
1哪里远你去哪里
有一个俗语叫做“哪儿凉快哪儿呆着去”,可说：
【take a hike】【take a walk】
这个短语在美国韦氏词典里很明确的被解释为 [go away] and [leave]
直译的句子可用：
Go the farthest that you can.
还有你关心的问题,句子结构.定语从句若有 you can 那么can 后面基本上都可以省略.
从句逻辑 you can (go) [the farthest](即先行词)
当然你也可以说
Go, as far as you can.
Go as far as possible.
第一句的as far as 这里不是连接词了而是真正的比较用法与...一样,这里的as 是个介词,
后面接的其实是一个宾语从句,you can = where you can go.
其实you can这个句子总是可以直接当做宾语从句来用的的.

Go as far as possible
Go as far as you can
你的那个是错的,是机器翻译的吧
