知识点拨
考点 01 as ... as ... 和……一样
It was as big as a room. 它和一间房间一样大。
It was as heavy as four elephants. 它和四头大象一样重。
▸ as + 形容词原级 + as，表示"和……一样……"。
解析：as ... as ... 是同级比较结构，中间的形容词用原级，不用比较级。
一、as + 形容词原级 + as
例句：The laptop is as small as a book. 这台笔记本电脑和一本书一样小。
例句：My schoolbag is as new as yours. 我的书包和你的一样新。
二、否定形式 not as ... as（不如……）
例句：The first computer is not as small as a laptop. 第一台电脑不像笔记本电脑那样小。
⚠ 易错提醒：as big as(√) as bigger as(✗) as ... as 中间的形容词用原级！
