（1）as...as..和（2）so...as..引导的定语从句分别怎么翻译？再举个例子？

as引导限制性定语从句详细用法讲解如下

as引导限制性定语从句时,通常和such,the same,as(so)等连用,构成such...as/such as,the same...as/the same as,as(so)...as等结构,即当先行词被以上词修饰/限定时，需要用关系代词引导定语从句并在定语从句充当主语,宾语和表语等成分。

(1)such...as/such as意为“...的那种...,像那样的”，such...as/such
 as引导限制性定语从句时,既可指人,也可指物。such用于名词之前时,具有形容词性质；such单独使用(即后面不接名词)时,具有代词性质。

(备注2：当定语从句省略谓语部分时，要用as。）

(3)as(so)...as意为“和...一样”,后接由many,much等修饰的名词或由形容词修饰的单数名词,注意其语序为as(so)+adj.+a+n+as。
