The reason she failed in the exam was______.5.The reason she failed in the exam was______.A.that she hadn't worked hard B.because she hadn't worked hard C.why she hadn't woeked hard D.because she was too careless
选A
这是一个表语从句,表语从句的引导词有：that, what, who, when, where, which, why,
whether,how.
所以because开头的肯定不对
而选项C不能用在这里reason为主语的情形,假如用why 的话,要这么说：
This was why she failed in the exam.
否则句子的意思都不对了.
A.that she hadn't worked hard
be 动词后面的表语用that 从句
A 填that引导的从句
A
that引导表语从句
她没有通过考试的原因是她没有好好学习。
用because和why的话，前面已经有reason，意思也不符合。
A.这是一个表语从句,应用代词that,what等引导.因此这里选a.
