其基本意思为“与…一样”，其中的第一个as为副词，其后通常接形容词或副词(用原级)，第二个as可用作介词(后接名词或代词)或连词(后接从句)。
使用时应注意以下几点。
如：
(1) 在否定句中，第一个as 也可换成so。
如：
He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。
(2) 在该结构的两个as之间通常接形容词或副词的原级，但若涉及数量或程度，可用“as much+不可数名词+as”和“as many+复数名词+as”。
如：

也可说。
如：She is a teacher as good as her mother.
但不说。
如：She is as a good teacher as her mother. / They are as good teachers as us.

I gave him as much as he could eat. 他能吃多少，我就给了他多少。

(6) 在非正式场合(尤其是美国英语中)，有时可以省略第一个as。

另外，若意思明确，有时可省略第二个as及其后的相关词语。
如：

“as + 形容词或副词原级+ as…”意为“和……一样”，表示同级的比较，但要注意第一个as 为副词，第二个as 为连词。
根据比较对象和性质的不同又可以把此种结构分为三种：
（一）“ as … as …结构”用于表示不同人或物同一性质的比较，意为“……和……一样…… " 。
例如The tree is as tall as the building(is) ．
这棵树和那栋楼一样高。
注意此结构也常用于形象比喻中：as cool as cucumber 沉着的，as stubborn as a mule 非常顽强的，倔强的，as clear as crystal 非常透明的，as poor as a church mouse 非常贫困的，as busy as a bee 像蜜蜂一样忙碌，as easy as ABC 像ABC 一样容易，as deep as a well 像井一样深，as light as a feather 像羽毛一样轻，as soft as butter 像黄油一样软。
这些短语生动活泼，浅显易懂，记住这些短语可以提高学生的英语写作和口语能力。
（二）“ as … as …结构”用于表示同一个人或物不同性质的比较，意为“既……又……”。
例如：
This swimming pool is as wide as it is long.

需要注意的是：“as + 形容词或副词原级+ as…”结构的变体形式是“ as + 形容词+ a + 单数名词+ as 或as + many/much + 名词+ as ”。
意为“……和……一样…… " 。
例如：
I don't want as expensive a car as this. ＝I don't want a car as expensive as this ．
我不要这么贵的汽车。
This is as good an example as the other is.
这个例子和另外一个例子一样好。
