请问这道题为什么不能选A，请详解下！

Answer 1

Quiet student as he may be，he talks a lot about his favorite singers after class.
翻译的话就是 尽管他是个安静的学生，他下课后谈论很多他所喜爱的歌手。

as引导让步状语从句时，状语表语及谓语动词的一部分置于as之前，且表语
中的冠词要省略。如：Try as we did we failed again.又如：Late as he
came he saw the famous man.而although则无此种用法，句中although应改为 as.

as引导让步状语从句时,常放在作表语,状语或谓语的一部分的形容词,名词,副词或动词原形之后.如果是单数名词或形容词的最高级作表语,不再用冠词.

however和as 引导让步状语从句时的区别：
however引导让步状语从句时，相当于no matter how,后面跟形容词或副词；as引导让步状语从句时，用倒装语序，即把作状语的副词或作表语的形容词或名词提前，而且如果作表语的是单数名词，前面不加冠词，也可以把谓语动词部分的实义动词提前。
〔误〕 As hard he works, he can’t catch up with his classmates.
〔正〕 However hard he works, he can’t catch up with his classmates.
〔析〕见上述说明。
〔误〕 A model worker he is, he remains modest.
〔正〕 Model worker as he is, he remains modest.
〔析〕as 引导让步状语从句，前面的单数名词前不加冠词.

Answer 2

这句话的意思是，“虽然他可能是个安静的学生，但在课后他也会谈论很多有关他最喜爱的歌星。”在这句话中，as引导让步状语从句，理解为“虽然”。as引导让步状语从句时，要用倒装形式，倒装的形式共有三种：表语提前，程度副词提前，还有就是动词原形提前。（表语如果是可数名词，要用零冠词）这道题中，a quiet student 是表语，要提前，而A多了一个冠词。

Answer 3

一个句子不能有两个主语。a中的前半句就是如此。

Answer 4

.A quiet student 没加S
