be welcome to 

If someone is welcome to someone or something, they can have it or do it, especially because it is not wanted by anyone else.

可以隨便擁有，可以隨意做(尤指那些不被別人看重的東西或事)

You're welcome to it - I can never get it to work right. 

你盡管用——我就從沒能讓它正常運轉(zhuǎn)過。

If they want to change the rules, they are welcome to try. 

如果他們想改變規(guī)則，盡可以試試。
