问题描述：
My former school is now very different from _ it was when I was there.
A.that
B.what
C.what
D.which
what指代的是什么呢?
答
what引导的是一个名词从句，from是个介词，后面需跟名词，只能用what，其他如that，which引导的定语从句，必须有先行词才行。what引导的句子表示我以前在学校时学校的样子。
答
what指代它在你还在那里时的样子
答
what 指以前的那个样子,what is was
这句话就是My former school is different from what it was.(when i was there)我的母校现在的样子已经和我在那个学校时的样子很不一样了
