as, which 非限定性定语从句 篇一
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.
The sun heats the earth, which is very important to us.
典型例题
1)Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗号连接。况且选he句意不通。
2)The weather turned out to be very good, ___ was more than we could expect.
A. what B. which C. that D. it
答案B。which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。
3)It rained hard yesterday, ____ prevented me from going to the park.。
A. that B. which C. as D. it
答案B.
as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
（1） as 引导的定语从句可置于句首，而which不可。
（2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。
在本题中，prevent由于是行为动词，所以正确选项应为B。
As 的用法
例1. the same… as;such…as 中的as 是一种固定结构， 和……一样……。
I have got into the same trouble as he (has)。
例2. as可引导非限制性从句，常带有'正如'。
As we know, smoking is harmful to one's health.
As is know, smoking is harmful to one's health.
As是关系代词。例1中的as作know的宾语；例2中，它充当从句的主语，谓语动词know要用被动式。
英语定语从句语法解析 篇二
1、限定性定语从句和非限定性定语从句
定语从句就其与先行词的关系而言，可分为限定性定语从句和非限定性定语从句。限定性定语从句和先行词之间没有逗号，表示对先行词起修饰限制作用；而非限定性定语从句和先行词之间有逗号分开，是对先行词进行补充说明，相当于并列句。
如：He is the man who has a strong personality. 他是个个性很强的人。（限定性定语从句）
My brother, who works abroad, is coming next week. 我哥哥在国外工作，他下周将回来。（非限定性定语从句）
注：
1) 非限定性定语从句不能用that来引导，一般用which，as或who（指人）。用which或as引导时，既可以修饰主句的部分内容，也可修饰主句的全部内容。如：
He spoke confidently, which impressed me most. （which指代整个主句，在从句中作主语）
2) as引导的非限定性定语从句既可以放在主句之前，也可以放在主句之后，但which或who引导的非限定性定语从句不能放在主句之前。如：As we all know, the moon is a satellite of the earth.The large area is covered with thick snow, which affects people‘s life greatly.
3) 在限定性定语从句中，关系代词作宾语时可以省略；但在 非限定性定语从句中，关系代词作宾语时不能省略。如：
The film （which) I saw last night is about a young teacher. (which可以省去）
She introduced me to her husband, whom I hadn’t met before. （whom不能省去）
2、只用关系代词that，不用 which，who或whom的几种情况
1)当先行词是all, everything, nothing, something, anything, little, much, none, few等时。如：All that you want are here.
2) 当先行词被all, no, some, any, every, a few, a little, much, only, very等修饰时。如：There is no person that doesn’t make mistakes.
3)当先行词被序数词或形容词最高级修饰时。如：This is the best film that I have ever seen.
4)当出现两个或两个以上的先行词，并同时兼指人和物时。如： We are talking about the people and countries that we have
visited.
5) 当主句是以which 或 who 开头的特殊疑问句时。如： Who is the person that is standing over there?
6) 当定语从句为there be 句型时，关系代词只用that，
但经常可以省略。如： I know the difference (that) there is between you.
7)当关系代词在从句中作表语时，常用that。如：He does not seem to be the man that he was
他似乎和过去不一样了。
3、 as 与其他词连用引导的定语从句
as 引导定语从句时，可指人也可指物，通常与the same，such，so等连用，形式为：the same… as，such… as，as …as，so… as。As在定语从句中可作主语、宾语、表语等。如：
She knew he felt just the same as she did. 她知道他的感觉与她自己的一样。（as代替事，作宾语）
I lend you such books as will interest you. 我借给你使你感兴趣的书。（as代替物，作主语）
注：the same… as 和the same… that的用法不同。as引导的定语从句表示其内容与主句所讲的事物“相似”，指同类事物；that引导的定语从句表示其内容与主句所讲的`事物是“同一个”，指同一事物。如：
This is the same pen as I lost yesterday. 这和我昨天丢的笔一样。（类似的笔）
This is the same pen that I lost yesterday. 这支笔就是我昨天丢的那支。（同一支笔）
4、“介词+关系代词”引导的定语从句
在“介词+which/whom”结构中，介词的选择取决于3种情况：
1)定语从句中谓语动词或表语的搭配。如： This is the college in which I am studying. He is the man about whom we are talking.
2)先行词与介词的习惯搭配。如： The speed at which the machine operates is shown on the meter.
仪表上显示出这台机器运转的速度。
3)当定语从句为最高级时只能用of which; 否则用其他介词。如： I have five dictionaries of which Longman Dictionary is the best. I have five dictionaries among which Longman Dictionary is published in UK.
注：不可拆分的动词短语介词不能提前，如put up with;有的短语可能有不同的介词搭配，此时需要根据上下文来确定。如：be familiar with/to，compare with/to等。
有时为表意清楚，还可以在关系副词where/ when前加介词from, to等。如：
China is the birthplace of kites, from
where kite flying spreads to Japan, Korea, Thailand and India.
中国是风筝的故乡，从这里，放风筝的运动传到了日本、韩国、泰国和印度。
注 定语从句和同位语从句的区别
定语从句在复合句中的功能相当于形容词，它对先行词起修饰、描述或限制作用。而同位语从句则属于名词性从句，对与它有同位关系得名词作进一步解释，使其内容具体化。例如：
She felt very sad because of the news that her husband was killed in an aircraft crash. （同位语从句）
The fact that she told me made me very angry. （定语从句）
