问题描述
Such a clever girl as she can learn anything quickly. (as she是介词结构做后置定语，as不是连词)
老师答疑
刘老师：
▲ as she是定语从句，she之后省略is，as作is的表语。
▲ as 既不是介词，也不是连词，而是关系代词，指代girl。
▲ as引导的定语从句主要有以下两种情况：
引导限制性定语从句，它的先行词之前有as, so, such, the same等修饰；
引导非限制性定语从句，其先行词是整个主句，as指代整个主句的意思。
一、as引导限制性定语从句，先行词前有as, so, such, the same修饰
当先行词前有as, so, such, the same等修饰时，关系代词常用as，它在从句中作主语或宾语的。
Such people as have made great contributions to the world should be greatly respected.那些对世界做出巨大贡献的人应受到极大的尊重。（as作从句的主语）
You may take as many chairs as you need.你需要多少椅子就拿走多少椅子。（as作need的宾语）
My parents have not so much money as I want.我父母没有我需要的那么多钱。（as作want的宾语）
He made the same mistake as you made in the last exam. 在上次考试中，他犯了跟你相同的一个错误。（as作made的宾语）
【注意】
1.在so/such...that...引导的结果状语从句中，that不作任何成分，只起引导作用。要注意区别这两种不同的结构。如：
They had such a fierce dog that no one dared to go near their house.他们家有一条凶狗，没人敢靠近他们家。（that引导结果状语从句，在句中不作成分）
2. the same后有时用that，它表示“同一个，就是那一个”的意思，而as则表示“与……一样”，但不是同一个。如：
This is the same cell phone that I lost yesterday.这就是我昨天丢的那部手机。
This is the same cell phone as I lost yesterday.这是与我昨天丢的相同的一部手机。
二、as引导非限制性定语从句，其先行词是整个主句
as也可以引导非限制性定语从句，先行词就是整个主句，它在定语从句中作主语、宾语。它引导的从句可以位于主句前，也可以位于主句后，还可以位于主句中间。
As everybody knows, Shakespeare was a great English writer.众所周知，莎士比亚是伟大的英国作家。（从句在主句之前，as作从句的宾语）
Tom is a brave boy, as is described in the report.汤姆是一个勇敢的男孩，这正如在报道中描述的那样。（从句在主句之后，as作从句的主语）
The project, as we had expected, got along well.正如我们所预料的那样，工程进展顺利。（从句在主句中间，as作从句的宾语）
as引导非限制性定语从句时，常见的【固定表达】：
as we all know众所周知 as I can remember正如我所记得的
as often happens像经常发生的那样 as we expect正如我们预料的那样
as you see这一点你明白 as was expected正如预料的那样
as can be seen看得出来 as may be imagined正如可以想象的那样
as has been said above 如上所述 as we all can see 正如我们都能看到的那样
as is often the case 像常规那样 as everybody can do 正如人人都能做到的那样
