题目内容
【题目】Human facial expressions differ from those of animals in the degree ___ they can be controlled on purpose.
A. with which B. for which
C. of which D. to which
【答案】D
【解析】考查定语从句。句意:人类的面部表情与动物的面部表情不同,它们在某种程度上可以被故意控制。to some degree“某种程度上”是固定搭配。其中in the degree to which they can be controlled表示范围,是状语;to which they can be controlled是定语从句,修饰degree。故选D。
