The woman with a pair of glasses is my mother对with a pair of glasses提问

Which woman is you mother?

which woman is your mother?
这里with a glasses 是做定语修饰woman的。故用which来问

您好，由我来回答您的问题。
提问如下：Which woman is your mother?
译文如下：哪一个是你的妈妈？
回答如下：The woman with a pair of glassses is my mother.
译文如下：那个戴着一副眼镜的女人是我的妈妈。

可以这样记，对主语后面的介词短语提问都用“which”
