Question

【题目】Human facial expressions differ from those of animals in the degree ________ they can be controlled on purpose.
A.with which
B.to which
C.of which
D.for which

Answer 1

【答案】B
【解析】句意：在控制力方面，人类的脸部表情与动物的脸部表情不同。in the degree to which they can be controlled表示范围，是状语。其中 to which they can be controlled是定语从句，修饰degree，to a degree“在某种程度上”，所以答案是B。
