Question

When he came back from abroad, John told his parents about the cities and the people ____ he had visited.

A．who

B．which

C．where

D．that

Answer 1

D

试题分析：考查定语从句。本定语从句的先行词是the cities and the people先行词既有人又有物，使用that，在句中做visit的宾语；who只能之人； which只能指物。Where在句中做状语。故D正确。
点评：当先行词既有人又有物的时候，使用关系代词 that。
