问题补充：

, he can speak three foreign languages fluently.

A. As he is a baby

B. As is he a baby

C. A baby as he is

D. Baby as he is

答案：

A. As he is a baby

B. As is he a baby

C. A baby as he is

(答案→)D. Baby as he is

解析：考查固定句式。固定句式：名词/形容词+ as/though+ 主语+be动词；表示让步状语。本题的Baby as he is=Although he is a baby;在变成倒装句的时候要省略系动词is。句意：尽管他是一个孩子，但是他却能流利地说三国外语。故D正确。
