The reason ____ she gave for not being present was ___ there was heavy traffic on her way here. A./,because B.why,because C./,that D.why , whether 答案是：C 为什么不是其它选项？尤其为什么不是C？ 请详细说明，谢谢！

Answer 1

答案应该是c吧,选b是因为你没有读懂句子的意思和结构！
主句是the
reason
was___“原因是什么”
很明显是表语从句，that引导(the
reason
was
because……绝对是错句！)
第一个空到was是reason的定语，还原为she
gave
(reason)for
not
being
present
……
可见，先行词reason在原句中做宾语，引导词可以省略
句子的意思是“她给出的没有到这的原因是来这的路上交通堵塞”
