二、(not) as…as 的用法
as……as 用于表示同级之间的比较, 中间可加形容词、副词原级和名词。意思是“和……一样……”。如：
同级比较的用法
His room is as big as mine.
He runs as fast as I do.
You should keep the room as clean as your brother’s.
请看as…as的其他用法：
as…as possible / sb can 尽可能……
We went there as soon as possible.
Listen to the teacher as carefully as
you can.
He went there as quickly as he could.
有些短语有几个意思：
as soon as 和……一样快；一……就……；
as much as 和……一样多；多达；
as long as 和……一样长；长达；只要；
as well as 和……一样好；和……一样；
as far as 远达
在否定句中也可说not so/as…as….
as…as 也可表示倍数:
This room is twice as big as that one.
这个房间是那个房间的两倍大。
同级比较用原形，as…as永不离；若是not so as，后强前弱不看齐。
同级比较 · 记忆口诀
同级比较一般用 as…as 表示“与……一样”，这时谁强谁弱不能比较出来，而not so…as则表示后者比前者强，翻译为“不如……”。

珍道具(Chindogu)，是一种奇特的发明形式。它的基本特点是在貌似解决一种问题的同时，又产生了一大箩筐，更多的麻烦，要不就干脆让人窘迫不堪，所以也就实在没什么实用价值。
珍道具从字面上讲，是稀奇（珍）+工具（道具）的结合，不过在英文被生生造出个Unuseless，倒是十分恰当。因为它宣称珍道具并非完全“无用”(useless)，可是实际又没办法使，也就算不上“有用”(useful)，于是只好被称作“并非无用”了。
