Question

According to a study carried out by an American university, when you eat has ______ on your mood as ______ you eat.

A．much of as an effect; what                B．much of as an effect; which

C．as much of an effect; what                D．as much of an effect; which

Answer

C

【解析】

试题分析：句意：据一家美国大学的研究，吃饭的时间与你吃的东西一样，对心情都会产生同样的影响。这里have an effect on对……有影响。as……as其中第一个as后不可以直接接名词； what引导的名词性从句,这里不是定语从句，因此不可以选用which。故选C。

考点：考查形容词的比较等级的用法。
