as引导的让步状语如果倒装的是一个有冠词又有形容词修饰的名词时,冠词到底省不省~

这个问题我也很纠结,我之前有看过相关的参考书,上面写 如果名词前面有形容词修饰时,as引导的倒装句中要保留不定冠词 A bad-tempered man as he is ,=(Although he is a bad-tempered man),he loves me deeply可是也出现过相关的高考题 答案却不加 2005年重庆高考题中:
27._____,he talks a lot about his favorite singers after class.
A.A quiet student as he may be B.Quiet student as he may be
C.Be a quiet student as he may D.Quiet as he may be a student 答案是B所以我们就尽量往高考方向靠拢吧,毕竟高考出错的概率很小,或许是参考书写错了.
