总结： 补充：as与which引导的定语从句的区别
在非限制性定语从句中，as 定语从句只可以指 代整个主句，位置可在_____、_______、______, as 本身有“正如。。。。”之意，常与之连用的 动词有know, see, expect, mention等词 2. which既可指代主句，也可指代主句中的具体词， 不过不可以位于______。“这一点，这件事” 1.
3.“whose+n.”引导定语从句修饰“物”时，可换 成“the + n. + of which”或“of which + the + n.”。 He lives in a big house ______ window faces the sea. He lives in a big house ______ faces the sea. He lives in a big house ______ faces the sea.

2. such...as...与such...that...的区别 such...as...中的 as 引导的是定语从句， 而such...that...中的that引导的是结果状语从句。 当as 引导定语从句时，as 在从句中一般作主语或宾语 。 而that引导结果状语从句时，that在从句中不作任何成 分，即从句是非常完整的句子。 This is such a difficult problem ______ all of us can’t work out.（从句中的work out缺少宾语，前面的as是关系代 词，用作work out的宾语。） This is such a difficult problem ______ all of us can’t work it out.（从句是完整的句子，前面的that只起引导从句 的作用，在从句中不作成分。）
