问题补充：

A modern city has been set up in was a wasteland ten years ago.

A. where

B. which

C. when

D. what

答案：

A. where

B. which

C. when

(答案→)D. what

解析：考查名词从句连接代词what的运用。句意为“十年前是一片荒地的地方建起了一座现代化的城市”。该空所填词要作介词in的宾语，且作从句的主语，由此可以排除AC，因为where，when是关系副词，只能作状语。Which引导的是定语从句，连接代词what引导一个宾语从句，“是一个什么样的地方”。选D。
