翻译一句英语，请进

It's been locked up by me. Never let it out!

这个句子是口语化的，lock up比较合适，2楼的imprison太正式了
let it + out 就可以了，get有些多余

It is closed by me. Don't let it out.

It has been imprisoned by me. Never let it get out.

I put it behind bars, please don't set it free.

It was locked by me,don't let it out.
简单明了。
