he doesn't know ______about it he doesn't know ______about it 为什么答案是 to whom to talk为什么whom前用to

问题描述:

he doesn't know ______about it
he doesn't know ______about it
为什么答案是 to whom to talk
为什么whom前用to

to 前置了 本身是talk to 一个固定词组 表示 和XX谈天
talk to sb。about sth。是与XX(人)谈论某事

怎么说呢,想想啊。先翻译吧。他不知道和谁谈论这件事。
第一个to是don't know to do
第二个to是talk it to sb.
whom是宾语前置了
Understand?
不明白就百度HI一下

他不知道要向谁去说这个.
to whom(向谁)
to talk(去说)
