关于as as的用法及解释
as是每个学习英语的人都需要掌握的，那么as...as作为它的固定搭配也是要求每个学生掌握。接下来小编在这里给大家带来as...as的用法及相关例句，我们一起来看看吧!
as as的用法
1. 基本用法
中间只能用形容词或副词的原级，不能用比较级或最高级。如果在第二个as之后使用独立的人称代词，一般说来用主格(较正式)或宾格(非正式)均可。如：
He’s as old as she [her]. 他年纪跟她一样大。
但是，若第二个as之后的人称代词跟有谓语动词，则该人称代词只能用主格。如：
He is as old as she is.
但是有时用主格或宾格含义差别很大：
You love him as much as I (=as I love him). 你爱他像我爱他一样。
You love him as much as me (=as you love me). 你爱他像爱我一样。
2. 用于否定句
在肯定句中用as…as, 在否定句中用not as…as或not so…as 均可。如：
He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。

你的房间与我的一样大。
