题型：不详难度：来源：

The reason _______ he was late was _______ he missed the bus.

A．why, that	B．why, because
C．that, why	D．because, why

答案

A

解析

试题分析：句意：他迟到的原因是他没有赶上火车。第一空是why引导的定语从句，why在定语从句中状语，先行词是reason；第二空是that引导的表语从句，that在表语从句中不做成分。固定句式The reason why……be that…,故选A。
点评：本题难度适中。定语从句及表语从句是高中英语语法中非常重要的内容，对它们的考查关键在于分析从句的成分，需要考生有分析理解复杂的句子结构的能力。
即学即练：The reason ______ he told me for his absence did not sound believable.
A. why       B. because
C. that     D. whom
解析：C。句意：他告诉我他缺席的原因很难使人相信。
