非 限 制 性 定 語 從 句
非限制性定語從句和主句之間常用逗號隔開，它與主句的關(guān)系不十分密切，只對先行詞作補充或附加說明，如省略，也不影響主句意思的表達。如：water, which is a clear liquid, has many uses.上述例子作如下改動，句子意思仍然完整： water has many uses.
一、 關(guān)于引導(dǎo)非限制性定語從句的關(guān)系代詞，須注意以下三點：
1.引導(dǎo)非限制性定語從句的關(guān)系代詞在指物時，只能用which，而不能用that；關(guān)系代詞which既可指代先行詞，也可指代前面整個句子的內(nèi)容。
如：he lives in weifang, which is only an hour’s ride from here.
(關(guān)系代詞 which 在定語從句中作主語，指代主句中的 weifang。)
i have lost my pen, which i like very much.
(關(guān)系代詞which在定語從句中作賓語，指代主句中的pen。)
new concept english is intended for foreign students, which is known to all of us.
(關(guān)系代詞which 在定語從句中作主語，指代整個主句的內(nèi)容。)
2.關(guān)系代詞 which 和as 引導(dǎo)非限制性定語從句時的區(qū)別：as 有“正如……” 、“就像……” 的意思， 而which沒有；as 引導(dǎo)非限制性定語從句時，在定語從句中作主語或賓語，可以放在主句之前或之后；而which引導(dǎo)的非限制性定語從句只能放在主句之后。
如：as is known to all, he is the best student in our class.
(as 指代整個主句，在定語從句中作主語。)
he opposed the idea, as could be expected. (as指代整個主句，在定語從句中作主語。)
