Much as I like you,I couldn’t live with you. 我尽管很喜欢你,却不能和你在一起生活。

6、补充说明 1)这类倒装的让步状语从句可用 as, though 来引导,不能用 although 来引导;但是,未倒装的让步状语从句却可用 though, although 来引导,而不能用 as 来引导。也就是说, although 引导让步状语从句时不能倒装,as 引导让步状语从句时必须倒装,而 though 引导让步状语从句时可以倒装也可以不倒装。如:
虽然很晚了,但我们还是继续工作。 正:Late as [though] it was,we still went on working.

Cold as it was, we went out.=As cold as it was, we went out. 尽管天气冷,我们还是出去了。 .. .下载可编辑. Successful as he is, he is not proud.=As successful as he is, he is not proud. 他虽成功了,但不骄傲。
二、as 引导定语从句 as 的用法:(as 引导定语从句, 在定语从句中作主语、宾语、表语)
(一) 如为限制性的,多用于the same …as ; the same as;such …as …; as many/much as;so …as等结构中。如:
1. I have the same book as you (have). 我有一本和你的一样的书。
Her attitude to him was quite the same as it had always been. (关系代词as和指示代词same连用, 在从句中用作表语, 先行词是same.)
