How is your mother doing? Is she getting better?

你妈妈怎么样？病情有好转吗？

Yeah. Thanks to doctor’s help.My mother is as good as new.

嗯，多亏医生的帮助，我妈妈恢复得像原来一样。

重点讲解:

My mother recovered well.

My mother is as good as new.

用My mother recovered well.表达我妈妈恢复得像原来一样。语法上没错，但是这个表达似乎显得很平淡，口语在表达“恢复得像原来一样”常用习语as good as new,字面意思是跟新的一样，引申为状况良好。
