The reason ______ he didn’t come was ______ he was injured. A．that; because B．why; that C．why; because D．that; that

Answer 1

B
试题分析：第一空考查
定语从句
，此处the
reason是
先行词
，其在定语从句中作原因状语，用why；第二空考查
表语从句
，he
was
injured是一个完整的句子，不缺成分，故用that；所以选B。句意：他为什么没来的原因是他受伤了。

Answer 2

填why
这一句是定语从句
the
reason是先行词
而从句he
was
ill
that
day非常完整。
所以用关系副词why
补充：若从句结构不完整，则用关系代词which或that
例如：the
reason
that/which
he
talked
about
is
good.
