一道英语选择题，疑惑类

I'll never understand_____ it came about that you were late three times a week
A.when B.what C. how D.why
为什么填how不填why呢？

Answer 1

这里有很强的语气，相当于一个感叹句故用how.

Answer 2

I'll never understand_____ it came about that you were late three times a week
A.when B.what C. how D.why
为什么填how不填why呢？
答：因为：how it came about that=why
译1：我永远也不能理解这件事（it) 究竟是怎样发生的。（哪件事啊？你问）就是：你一周迟到三次这件事。
译2：你一周迟到三次，我永远也不理解这事是怎样发生（came about)的。
译3：我将永远也不理解你为什么会一周迟到三次。
我想口语中的how come就是由这个来的：
How come you were late three time a week?

Answer 3

选C
因为come about是发生的意思，这里的句意是我很难理解你一周迟到3次这种事是怎么能够发生的。。
that you were late three times a week
整个句子是前面it 的同位语从句，表示你迟到的这事儿

how it come about 这事儿是怎么发生的 how强调的是怎样
如果变成why it come about 意思就是 这事情为什么会发生
根据句子意思 想表达的应该是：我真的很难理解这种迟到行为是怎么可以这样的。
要用why 的话 其实直接 I'll never understand why you were late three times a week就好 表示我很难理解你迟到的原因

Answer 4

C
how it came 表示说话者不解的语气，实际包含了why啦

Answer 5

首先，把整句话分成大的两部份，I‘ll never understand主句和后半句从句。然后看后半句，如果用why则为why it came about that you werelate，句子结构不对。如果是how,句子为how it come about that you were late,it为形式主语，that从句是真正的主语，整句话就是你一周迟到第三次这件事怎么会发生，用了how it came about that的句型。你的问题主要在语法结构方面，多加强练习吧，不懂可以问我哦↖(^ω^)↗

Answer 6

"how it come about that..."是以固定句式，表示“...是怎么回事”，相当于why.
