He has proved doubters wrong by progressing himself as far as he has这里 as far as 后面怎么接he has

He has proved doubters wrong by progressing himself as far as he has这里 as far as 后面怎么接he has
【as far as he has】这里是起到一个强调作用,强调他做到了.
意思是把前一句的意思再重复了一遍.
句意：他应经通过自己的进步,证明那些怀疑他的人是错的,他尽自己的能力做到了（证明了）.

as far as 做连词。所以后面加句子。
As far as i know ,he is very poor .
