Question

If you are travelling _______the customs are really foreign to your own, please do as the Romans do.

A．in which

B．what

C．when

D．where

Answer 1

D 

试题分析：考查地点状语从句：句意：如果你到文化风俗不熟悉的地方旅行，要入乡随俗。Where引导地点状语，相当于in the place where…,意思是：在…地方。选D。
点评：where引导地点状语从句相当于，先行词in the place where，不能和定语从句混用，这是在句中充当状语从句的，做题要分析句子成分。
