英语翻译It's not ________ to______前面那个填for teenagers我会 就是这个often加哪里啊

为你解答。
经常熬夜对青少年不好。
It's not （good for teenagers） to （stay up late too often）.

It's not good for teenagers to often stay up late.

It‘s not good for teenagers to stay up too often.
亲,把它放最后,做副词就好啦!
如果没有这个框框限制,这么翻译会更好些：
Staying up too often will do no good to teenagers.
