题型：不详难度：来源：

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

A．they

B．where

C．what

D．that

答案

D

解析

试题分析：考查定语从句，先行词是small houses，定语从句缺少主语，用关系代词that或which，但是不能省略，句意：古镇哟哟狭窄的街道和彼此挨得很近的小房子。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,缺少状语用关系副词，缺少定语用whose。
