请帮忙翻译：“这个杯子太贵了，我舍不得用”，

This cup is so expensive that I can't bear to use it.
比如：It's so beautiful that I can't bear to eat it.这盘鱼真美，我都舍不得吃它了。

This cup is extremely expensive. I will stint it.

查了一下汉英字典，可以用begrudge: 她舍不得穿那件新裙子。She begrudged wearing her new skirt.
I begrudged using this cup for it's too expensive.
或者This cup is so expensive that I begrudged using it.

As to me,this cup is too expensive to use.

这个杯子太贵了，我舍不得用

I am unwilling to use this cup because it is too expensive.

这样就可以了

This cup is so expensive that I can't bear to use it.
