问题描述：
—Who is the woman ___ is talking to our English teacher?—Our Chinese teachet .
划线上应该填什么（说明理由）
答
who.这是个定语从句,先行词是人.
答
—Who is the woman (that) is talking to our English teacher? —Our Chinese teachet .
这是一句定语从句，that is talking to our English teacher是来修饰the woman，翻译成和我们英语老师谈话的女士
因为这是一句问句，特殊疑问词是who，所以为了避免重复，后面括号内用that.
答
that 引导定语从句
