中文意思是你母亲去世了
Don't be so modest. When your mother died, you... You stepped right in and you became the mother. You took good care of Kevin and your Dad.别这么谦虚。*妈死的时候…你站了出来,你成了妈妈。你把你的父亲和凯文照顾得很好。
“Your mother died.”是一个一般过去时的肯定句,我们可以拆开看成分一个一个的翻译。your的意思是你的,mother的意思是妈妈,因此主语就是your mother,翻译过来就是你的妈妈,而died是动词die的过去式,所以your mother died的意思就是你的妈妈去世了。
