一个令人困惑的英语问题

要分开：

as soon as可以接从句引导时间状语：“一...就...”
I will tell her as soon as I see her. 我一看到她就告诉她。

as quickly as 要接名词：“和...一样快”
He runs as quickly as me. 他和我跑一样快。

as early as 可以接从句和名词：“当...的时候”、“和...一样早”
I began to go to school as early as I was 6.我6岁时开始上学。
He gets up as early as me.他和我起得一样早。

后跟adjective,表示尽..尽

不一定都是形容词，一般是as soon as ,as quickly as ,as early as后加“possible”，是“尽可能……”的意思。
但也可以这样使用“as soon as I can/we get there/you come back”后面加类似状态的短句

一般后跟副词或形容词，怎么说呢， 你看看下面的例句，仔细理解一下，你会发现他们的不同点，看多了，用多了，你的感觉就来了，呵呵

as soon as possible 尽可能的快

as quickly as possible 尽快，尽快地。。。

as early as possible 尽早的

大致上,就在于你把这些用在什么地方
比喻说:as soon as possible 就是越早越好,as quickly as possible 就是越快越好,as early as possible 就好像as soon as possible 一样.
也可以用 as qiuckly as you can

再比如说:as qiuckly as horse(这个语法有点错误)
as fast as a horse(就好像中文的比谕句)
=和马一样快

as ___as 的意思就是 像______一样
