例：They visited the city of Hangzhou，which is famous for its beautiful scene．他们参观了杭州城，它以风景秀丽而闻名。
非限定性从句中关系词指代整个句子时，用关系代词which。试比较：
①Big floods hit some parts of China in the summer of 1998,which caused a great damage to the country．1998年夏中国部分地区遭受特大洪灾，给国家带来了巨大损失。(指代整个句子)
②They got married on July 1，1997，when Hong Kong returned to our motherland．他们于1997年7月1日喜结良缘，香港在这一天回归祖国。(指代时间作状语)
学习中应注意的问题(一)
1)先行词为表示时间或地点的名词在从句中作主语或宾语时关系词的使用。当先行词为表示时间或地点的名词时，在从句中作主语或宾语时，应使用代词which或that，不能用副词when或where．
①a：I'll never forget the days which/that I spent in the country．(which作spent的宾语)
b：I'll never forget the days when I worked in the country．(when代替in the days作状语)
②a：They came to the small village，which was hundreds of miles from the city．(which在从句中作主语)
他们来到这个小村，小村与城市相距几百英里。
b：They came to the small village，where not more than l00 villagers lived．(where代替in the village作状语)他们来到这个小村庄，那里的村民不超过一百人。
2)the time，the way等为先行词时关系词的使用。
(1)先行词为time／moment等表示时间的名词时，用关系词when，that均可，且可省略。
例：By the time (when／that) they arrived，the house had been destroyed completely．等他们到达时，房子已完全烧毁了。
(2)the way用作先行词，关系代词作介词in的宾语时，通常介词与关系代词可以同时省略；如不使用"in"，则不能用关系代词。
例：He hated the ways(which／that)she talked (in)．他不喜欢她说话的方式。
3)关系代词只使用that，不使用which的情况。
(1) 关系代词前有形容词的最高级修饰时。
This is the funniest drama that I have seen.这是我看过的最滑稽的剧。
(2)先行词为不定代词。如：all，everything，nothing，anything，both．either，much，little，none。
例：①Everything that was taught in class seemed easy for him. 对他来说课堂上教的一切似乎很容易。
(3)先行词为only，very等词修饰肘。
例：①It was the only textbook that could be found．这是能够找到的仅有的一本课本。
②This is the very dictionary that I want to get．这正是我想得到的词典。
(4)定语从句中固定短语动词和短语中的介词不能前置。
例：It was the maths book that the boy was in search of．这是这个男孩正在寻找的数学书。
5)whose与of which/whom
(1)都可表所有关系。
(2)of which/whom还可表示"其中的……"(整体的部分)
例：He told us many stories about Long March，of which this is a good example.他给我们讲了许多关于长征的故事，这是其中一个很好的例子。
as和which引导的非限制性定语从句比较:
下面是近年高考题中关于定语从句的试题
1.The result of the experiment was very good, ____ we hadn't expected． (NMET2000，10)
2.Dorothy was always speaking highly of her role in the play，____,of course，made the others unhappy.
(NMET2000，17)
A.when B.which C.this D.what
3．Carol said the work would be done by October,____ personally I doubt very much．(NMET99，19)
A.it B.that C.then D.which
4.The weather turned out to be very good,____ was more than we could expect. (NMET94,39)
A.what B.which C.that D.it
它们的答案分别是C、B、D和B，都是用which引导一个非限制性定语从句，which代替逗号前整个主句的内容。
但有时关系代词as也可引导非限制性定语从句，as也是代替整个主句的意思。如:
As we all know，he never smokes. The foolish boy made the mistake again，as could be expected. ____ is mentioned above，the number of students in senior high school is increasing．('99上海，4)
A.Which B.As C.That D.It
关系代词as和which引导的非限制性定语从句区别究竟在哪里呢?
1．非限制性定语从句位于句末，而且as或which在从句中作主语、宾语或表语时可互换。如:
He is a farmer as/which is clear from his manners．(在从句中作主语)
This elephant is like a snake，as／which anybody can see．(在从句中作宾语)
2. which引导的非限制性定语从句一般放在句末，而as引导的非限制性定语从句可放在句末，也可放在句中、句首。置于句首时，不能用which替换。如：
Crusoe lost his dog, which made him very sad.
Taiwan is part of China, as/which is known to all.
As we have see
