as引导的让步状语从句的确需要倒装,而while则不需要
adj+as sb be young as he is ,he can do a lot of things 尽管他很小
N+as sb be child as he is .尽管他是个孩子
ADV+as sb does well as he does 经管他做的很好.
首先,AS引导的让步状语从句的倒装说明as是必须要存在的,具体的三种情况如下：
形容词+as+sb+be/实意动词 译为：尽管某人是怎么样的或尽管某人看起来怎么样.当然sb可以换做sth,之所以这里还可以用实意动词,其实就是系动词,因为系动词也可以跟表语（形容词）,比如尽管某物闻起来怎么样,尝起来怎么样.
名词+as+sb+be 译为：尽管某人是什么,比如：尽管他是孩子,只能用be动词
副词+as+sb+实意动词 译为：尽管某人做的如何,因为是动作,所以要实意动词,并且是副词修饰.
其实很容易,比如原句though he is young ,根据第一个套法.young as he is
原句though he makes it well 根据第三种套法：well as he makes it
原句 though she is a girl 根据第二种套法：a girl as she is
再问： a girl as she is 这句应该改为girl as she is .名词前的冠词应去掉
再答： 应该不能去掉，还原后还应该是 a girl as she is
