Question

The reason ____he was late was ____he had taken a wrong bus.

A. why; becauseB. for; because ofC. why; thatD. for; that

Answer 1

答案C
试题分析：考查固定句型和短语从句。固定句型：The
reason
is/was
that…原因是…；that引导表语从句。第一空是定语从句why
he
was
late修饰先行词the
reason.句意：他迟到的原因是乘错了公交车。故C正确。
考点：考查固定句型和短语从句
点评：固定句型：The
reason
is/was
that…原因是…；that引导表语从句；另外当先行词是reason的死后，如果使用关系副词，要使用why。

Answer 2

c
试题分析：考查定语从句和表语从句。本题使用的是固定句型the
reason
why...is
that...“......的原因是......”。从句he
was
late不缺成分，先行词是the
reason，因此，定语从句用why引导，for不能引导定语从句，排除b、d；was后跟从句作表语，从句he
had
taken
a
wrong
bus是主谓宾结构，不缺成分，用that只起引导作用，排除a；故选c。
