Question

【题目】 At long last the child was found on top of ______ we call the museum of science and technology.

A. which B. that

C. what D. where

Answer 1

【答案】C

【解析】

试题分析：考查名词性从句。句意：最后，这个小孩在科技馆的顶上被发现了。On top of 在顶部。we call the museum of science and technology做of 的宾语，call sb sth，call缺少宾语，故用what 来引导，介词的宾语从句。
