Question

The old town has narrow streets and small houses ______ are built close to each other.

A．they

B．where

C．what

D．that

Answer 1

D

试题分析：考查定语从句：先行词是narrow streets and small houses，定语从句缺乏主语，定语从句用that引导，句意：这个古镇有狭窄的街道和小房子，彼此建的很近。选D。
点评：考查定语从句一要看先行词，而要看从句的成分，如果缺少主宾表，要用that或which如果缺少状语，要用关系副词where，when或why。关键的定语从句的动词。
