感叹句口诀：
感叹句，并不难，what与how应在前。 形容词、副词跟着how, what后面名词连。
名词若是可数单，前带冠词a或an。
主语、谓语放后面，省略它们也常见。
定语从句中as的用法
As 属于关系代词，可以用来指代人，也可用来指代物；
既可以引导限制性定语从句，也可用来引导非限制定语从句。
“as” in the restrictive attributive clauses.
比较下列几组句子，总结as在限定定语从句用法。
He is a good teacher that/who/whom all the students like.
He is such a good teacher as all the students like.
You have to pay as much money as the victim requires.
You have to pay much money that the victim requires.
My father wants to buy the car that/which is on the stage.
My father wants to buy the same car as is on the stage.
“as” in restrictive attributive clauses
As 在限制性定语从句中常用于:
such… as…
the same…as…
as… as…
so… as…
attention
与 “so/such…that” 引导的结果状语从句的区别：
结构形式不同
表达句意不同
He is such a good teacher as all the students like.
He is such a good teacher that all the students like him.
Ⅱ. 有时用 the same限定先行词时，关系代词会用that来引导限制性定语从句，此时强调从句的关系代词和主句的先行词为同一个人或事物。而as则指同一类人或事物。
This is the same pen that I left on my desk yesterday.
This is the same pen as I left on my desk yesterday.
2. “as” in the non-restrictive attributive clauses.
比较下列几组句子：
Light travels faster than sound, which is known to all.
Light travels faster than sound, as is known
to all.
As is known to all, light travels faster than sound.
Light, as is known to all, travels faster than sound.
as引导的 从句位置十分灵活，
而which引导的从句只能位于主句后。
Summary
在限制性定语从句中：
在非限制性定语从句中:
such… as…
the same…as…
as… as…
so… as…
as引导的 从句位置十分灵活.
