7、从句1. 关系代词as在限制性定语从句时，在从句里做宾语时，绝不能省略。2. 当先行词被 the same 所修饰时，关系词既可以用 as，也可以用 that。不过一般说来，表示同一种类多用 as，表示同一事物多用 that。但是表示抽象概念时，同种类和同一事物是没有绝对区别的，所以as和that可互换。3. as引导的非限制性定语从句位置较灵活,可以位于主句前面中间或后面,一般用逗号与主句隔开。4. as引导非限制性定语从句。as在定语从句中做主语、表语或宾语。as代指整个主句，而as引的这个定语从句是用来补充说明整个主句的，可以放在主句之前或者之后。5. as常用于be known/ ex
