问题描述：
our school has changed greatly in the past 3 years改同义句!
our school is —— different from —— it was in the past 3years。
答
Our school is 【quite】 different from【 what 】it was in the past 3 years.
我们学校与它三年前的模样截然不同了.
quite 与greatly 对应.不应该是 how it is 么？不可以。这里的what 引导宾语从句，并且在从句中充当表语，而how 是副词，不可以作表语。初中生听不懂啊！！就是没有how XX XX这个结构对么？
