Question

英语语法问题-请从语法成分和时态方面帮我解析下这句话

下面说的是 定语从句中引导词只能用that的情况。

当先行词为主句的表语或者关系代词为从句的表语时。

例如：

This is the book that was bought yesterday.
这就是昨天买的书。

Our school is no longer the school that it used to be.
我们的学校不再是以前的学校了。

请问第二句里，Our school is no longer the school that it used to be. ，里的that是做的从句it used to be that 的表语？？？？

Answer 1

Our school is no longer the school that it used to be. 句子中的that 是引导定语从句it used to be 的，并且充当be 后面的表语。你的理解是对的。
