人们应当知道这个地方。

People shall know the place.

youdao

我问他们其中的一个人，‘你们怎么知道这个地方的？’

I asked one of them, 'How do you know about this place?'

youdao

“见鬼，”我插话道，“连我都知道这个地方为什么不能用断言。”

"Heck," I put in, "even I know why you don't use assert here."

youdao

Oh, I know this. I've been here before and I know this place very well,

哦，这个我知道，我去过那里，我对那个地方很熟悉。

出题者想要我找出一个函数,它在经过两次求导后得到数字a,我知道这里的某个地方,这个结论告诉我,我每求一次导,t就降一次幂
