单选题Thereason____hehadtolookafter

单选题 The reason ____he had to look after his mother at hospital was not the one ____he gave to us.A.why, whyB.that, whichC.why, thatD.that, why

C解析试题分析：在…he had to look after his mother at hospital定语从句中不缺主语和宾语，所以不用that，故排除BD；the one代替The reason避免重复，在…he gave to us定语从句中缺少gave的间接宾语，why不能作宾语，故排除A，所以应选C。考点：考查定语从句的用法。点评：本题难度适中。定语从句是高中阶段的重难点之一，也是高考的热点，需要考生有分析理解句子的结构的能力，牢记关系词的用法及区别。定语从句是英语语法中非常重要的内容，在阅读和理解过程中起着极其重要的作用。即学即练：Football is a game _____is liked by most boys.A. why B. when C. where D. that解析：D。句意：足球是大多数男孩都喜欢的游戏。
