问题补充：

In learning English they’ve reached a degreethey can read foreign newspapers and magazines in almost a free way.

A. but

B. what

C. which

D. where

答案：

A. but

B. what

C. which

(答案→)D. where

解析：句意：在英语学习中他们已经达到了一种几乎可以自由阅读英文报刊的程度。由句意可看出题干中空白处缺少一个引导定语从句的关系词，此处where引导一个表示抽象地点的定语从句，所以选D。

考点: 考查定语从句的用法。
