Question

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

A．why, because

B．why, that

C．that, why

D．because, why

Answer 1

B

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，它在从句中作状语，that引导的表语从句，that在从句中不作成分，the reason why…be that…故选B。
点评：本题的难度适中。考查表语从句与定语从句放在一起，增加了试题的难度，考生容易误选A，提醒考生注意判断从句中的连词必须会分析句子成分。
即学即练：The point is not who said the words,_________they are true or not.
A. but whether            B. and whether
C. but how              D. and how
解析：A。此题涉及两个搭配：一是not ... but ...（不是……而是……）;二是 whether ...or not （是否）。根据句意，选A。
