as 和 which 引导的非限制性定语从句的区别
先让我们看一道高考试题：
2004 年江苏英语高考题第 33 小题
＿＿＿is often the case, we h**e worked out the production plan.
． which ｂ．when ｃ．what ｄ．as
我们知道， as 可单独引导非限制性定语从句，作用相当于 which ，那么在非限性定语从句中究竟用 as 引导还是用 which 引导呢？现归纳如下：
．从 as ／ which 在句子中位置来区分
as 和 which 都可以指代主句中的一部分或整个句子的内容，有时可以互换，但 as 引导的非限制性定语从句位置比较灵活，可以位于主句前面，中间或后面，一般用逗号与主句隔开，而 which 所引导的非限制性定语从句只能放在主句之后。例如：
１） as is expected, our school team won the football match.
２） our team lost the game, as/ which was reported in the news*****.
３） mother was terrified, as/which i could see from her eyes.
．从 as ／ which 在句子中特定含义来区分
as 在引导非限性定语从句中有时有“正如”、“正像”之意，而 which 则无此意。常用句型有： as we all know, as is known to all, as everybody can see, as is expected 等。
如：１） as we all know, ***** was first made in china.
２） the earth runs around the sun, as is known by everyone.
３） as anybody can see, the elephant is like a snake. 或： the elephant, as anybody can see, is like a snake.
或： the elephant is like a snake, as anybody can see.
．从主从句意义匹配要求来区分
as 引导的从句在意义上不能与主句相抵触，而 which 则不受此限制。试比较：
１） she did the experiment successfully, as had been expected.
２） she failed in the experiment, which was unexpected. 由“位置”关系分析可知，上述高考题 as 是指后面“ we h**e worked out the production plan. ”整个句子的内容，故正确答案应选择ｄ。
as和which的区别
1. as通常和such, so或the same搭配，as引导的定语从句的谓语动词通常是see, expect, say, hope, happen, know等。如：
1）i wish to h**e such a radio as you said.我想有一台你说的那样的收音机。
2）i h**e the same opinion as you (h**e).我和你有相同的看法。
3）as often happens, he is late again.他又迟到了，这是常事。
4）the great wall, as is well known, is one of the wonders in the world.
众所周知，长城是世界上的奇迹之一。
5）tom is tall, as are his brothers.汤姆个子高，他的兄弟们也都是高个子。
6）frank is a fine athlete, as was his father before him.弗兰克是个优秀的运动员，在他之前，他父亲也一样是个优秀运动员。
7）i tr**el to london every day, as do most the people who live in this village.我每天乘车去伦敦，住在这个村子里的大部分人都是这样。
8) he is an englishman， as (=which) i know from his accent.他是个英国人，这一点我是从他的口音上得知的。
9) he was late for school, as is often the case. 他像往常一样上学迟到了。
10）as was usual with him, he went out for a walk after dinner.他又像往常一样，吃完饭出去散步了。
11）as is announced in today’s news*****, the steel workers of our country h**e fulfilled their production quota ahead of schedule.今天的报纸宣布，我国炼钢工人已经提前完成了生产指标。
12）as i was saying, we expect 2009 to be a good year.正如我刚才说的，我们期望2023年是个好年头。
13) as everyone knows, the farming industry is in serious difficulties.众所周知，农业面临严峻困难局面。
14）as i mentioned in my last letter, i’ll be back in ohio in june.正如我上一封信提到的，我将在六月份回到俄亥俄州。
．＿＿is known to everybody, the moon tr**els around the earth once every month. （nmet2001 ）
． it ｂ．as ｃ．that ｄ．what
解析］本题 as 引导从句的意思是“……事实，正如……”故 as 引导的非限定性定语从句修饰整个句子， as 在从句中充当主语，所以本题的答案是ｂ。
might be expected, a knowledge of psychology is essential for good advertisement.
a ． what ｂ．that ｃ．as ｄ．which
解析］虽然 as 和 which 都可引导非限制性的定语从句，代替整个句子或某个成分；但 which 引导的非限制性定语从句不可置于句首。故正确答案选择ｃ。
because of, due to, owing to, on account of和thanks to的用法比较：
这一组词都表示"由于"的意思，在使用时应该注意以下区别：
1．because of意为"由于，因为"，强调因果关系，在句中仅作状语，修饰句中的一部分，与其他成分不用逗号隔开。
如：we must not get discouraged because of such a minor setback．
我们决不可因为这样一个小小的挫折而灰心丧气。
2．owing to与because of一样，也强调因果关系，除作状语外，也可作表语。作状语时修饰整个句子，可在句首或句末，用逗号隔开。
如：they decided to cancel the flight，owing to the storm．
由于这场暴风雨，他们决定取消这个航班。
his death was owing to an accident．他死于一场事故。
