AS和Which引导非限制性定语从句
AS和Which引导非限制性定语从句关系代词as 与which引导非限制性定语从句可以用整个主句作为其先行词，指代上面或下文所说的一件事。
但何时用as，何时用which，时常出现差错。
现就as 与which在引导这种定语从句时所出现的不同词义和句法特点进行对比、分析如下。
一、as引导的从句表示说话人对话语的看法、态度、解释或评论。
一般有以下特点：1、此时的as仍具有“正如、象、由……而知、与……一致”等某些作连词时的语义。
翻译时有时可不必译出。
如：Shakespeare is a famous writer, as we all know. 莎士比亚是著名的作家，这众人皆知。
She is very patient, as is shown in her work. 她很耐心，正如她工作中所表现出来的一样。
2、在句法上，as常用作一些实意动词(如see, know, hear, watch, remember, say, tell, show, expect, guess等)的宾语，这类动词与as几乎成了一种固定搭配。
如：Einstein, as we know(=as is well known), is a famous scientist. 众所周知，爱因斯坦是一位著名的科学家。
There was a net bar around here, as I remember. 我记得这儿附近有一家网吧。
3、当从句的谓语动词是否定形式或从句谓语动词带的是一个复合宾语结构时，一般用which而不宜用as。
如：You pretended not to know me, which I didn’t understand. 他假装不认识我，我真不明白。
He admires everyone in the class, which I find quite strange. 他羡慕班里的每个学生，我认为太奇怪了。
as,which引导非限制性定语从句
3. as代表前面主句意思时，有“正如…； 就象……”之意，而which没有此意思， 从句中的动词常是expect, know, see, think, want, suppose等。
He won the match, as we had expected. He agreed to the plan, as was expected. The police were looking for him, as he thought.
1. as, which 都可引导非限制性定语 从句，指代整个主句的内容。 2. 非限制性定语从句位于句末、且 as 或 which 在从句中做主语、宾语、 表语，两者可以替换。
She failed in the exam, which / as was natural. (做主语） He is an honest boy, which / as anybody can see. (做宾语） The man seemed a German, which / as in fact he was. (做表语）
This kind of computer, as is wellknown, is out of date.
As we have seen, oceans cover more than 70% of the earth.
4. 当先行词为整个主句时，从句位 于主句之前或主句句中，只能用as。 如： As we know, smoking is harmful to one’s health. This kind of computer, as is wellknown, is out of date.
5. 当先行词为整个主句时，在从句 中作主语，谓语是主动语态，常用 which。如： He tore up my photo, which upset me. He said nothing, which made her angry.
2022年高考英语基础过关练 句法之as和which引导非限制性定语从句的区别(解析版)
2022年高考英语基础过关练20句法之as和which引导非限制性定语从句的区别1.My grandfather is fond of talking about the good old days, ___ is often the case with old people.A. whichB. whenC. asD. it【答案】C【解析】考查固定句型。
句意：就像老年人通常的情况那样，我的祖父喜欢谈论过去的美好时光。
as is often the case with...是一个固定句型（非限制性定语从句），意思是“就像/正如……情况一样”。
故选C。
2.Creating an atmosphere ________ employees feel part of a team is a big challenge.A. asB. whoseC. in whichD. at which【答案】C【解析】句意：创造一种雇员感觉是其中一员的氛围是一个大的挑战。
这是一个定语从句，in the atmosphere “在氛围中”是一个固定搭配。
此处也可以是where. 分析句子结构和结合四个选项，知道在这里面所需要填的是连词。
然后空格之前是一个名词，这种情况首先考虑的是定语从句。
然后分析之后的句子是具备完整的结构（有了主语employees和宾语part of a team）所以这应该是需要一个充当状语的连词，如where, when , why. 由于when用于时间，Why用于原因，剩下的使用where，所以这里填where。
但是答案没有这个选项，根据搭配介词+which="where" 及in atmosphere 是固定搭配，故选C。
【点睛】考查定语从句，本题涉及”in+关系代词which“引导的限制性定语从句。
3.The number of smokers, _____ is reported, has dropped by 17 percent in just one year.A. itB. whichC. whatD. as【答案】D【解析】句意：据报道，吸烟者人数仅（过去）一年就减少了17%。
