I dont know why he was late.这个句子里为什么用why不用that?
我打错了　是Idont know the reason why he was late

“I don‘t know the reason why he was late."
why 是修饰reason的,the reason why ,就好比the people who(whom),差不多算个固定搭配吧.定语从句
这里不能用that的.
"I dont know why he was late" 也好顺的喔.
可以看做把“the reason”省略了.
这里that也对的,就是意思不一样了.

I dont know why he was late.这个句子里为什么用why不用that? I dont know the reason why he was late 为什么不用that I dont know why he was late for school again. I dont know why he was late for school again.（同义句转换） why?I dont know! I DONT KNOW WHY YOU WERE LATE FOR SCHOOL AGAIN THE REASON WHY HE WAS LATE WAS THAT HE MISSED HIS TRAIN.为什么要 All people know why he was late 改为否定句】 This is reason ()he was late 括号里可以填why/ that 还是其他? why is he late?翻译成他为什么迟到了那why was he late 肿么译 that,he,for,school,is,why,was,late.快,加急有dont know why这个词组么,
