参考答案:B进入在线模考
【译文】简再笨也不可能做这种事。 
【解析】as引导让步状语从句的用法。as引导让步状语从句时,从句的补语(表语)或状语置于句首,则从句主谓倒装。补语若是名词,前置时不用限定词。如:Rich as he is,I don’t envy him.(尽管他是那么富有。我并不羡慕他。)Teacher as she is,she is not capable of teaching an subjects.(尽管她是老师,她也不可能会教所有的课程。)though与as有相同的用法,如:Clever though you may be,you cannot work out this problem.(虽然你很聪明,但也做不出这道题。)
