Peter is a good student,_his best subject.A.as English B.English as C.being English D.English being

问题描述:

Peter is a good student,_his best subject.A.as English B.English as C.being English D.English being
为什么选D?求详解,

D是一个独立主格结构,用作状语:English逻辑主语 being逻辑系动词 his best subject逻辑表语
C中being 和English 的位置错误;as 是“作为”,词义错误
