Disabled __ Liu Wei is,he can play the piano very well with

B.as
这是倒装句,相当于though Liu Wei is disabled
as / though引导的让步从句必须将表语或状语提前（形容词,副词,分词,实义动词提前）.但需注意：
1） 句首名词不能带任何冠词.
2） 句首是实义动词,其他助动词放在主语后.如果实义动词有宾语和状语,随实义动词一起放在主语之前.例如：
Try hard as he will,he never seems able to do the work satisfactorily.他工作很努力,但总不能让人满意.
