GRAMMAR非限制性定语从句高考考点点拨考点一：关系代词引导的非限制性定语从句【考例】用适当的关系词填空。

设空处引导非限制性定语从句，补充说明先行词people，且在从句中作主语，故填who。
2. which。
设空处引导非限制性定语从句，补充说明先行词the book Sherlock Holmes，且由recommend sth. to sb.可知，关系词在从句中作宾语，故填which。
3. whose。
设空处引导非限制性定语从句，补充说明先行词books，且设空处在从句中作从covers的定语，故填whose。
Period Three Grammar，Speaking & Writing一、非限制性定语从句的用法非限制性定语从句与先行词的关系不十分密切，只是起补充说明作用，缺少也不会影响全句的理解。
在非限制性定语从句的前面往往有逗号与主句隔开，若将非限制性定语从句放在句子中间，前后都需要用逗号隔开。
常见的引导词有：who，whom，which，as，whose，when，where。
注意：that，why不用来引导非限制性定语从句。
The sun，which rises in the east，gives us heat and light.太阳从东方升起，带给我们光和热。
二、非限制性定语从句应注意的问题1．关系代词as和which(1)关系代词as既可引导限制性定语从句，也可引导非限制性定语从句，as在从句中作主语、宾语或表语。
as引导非限制性定语从句，既可在主句前，又可在主句后，有时还可插入主句中；而which引导的非限制性定语从句只能置于主句之后。
相同的是两者都可指代主句的整个内容。
As is known to everybody，the moon travels around the earth.众所周知，月亮绕着地球转。
The weather turned out to be very good，which was more than we could expect.出乎我们意料的是，天气变得非常好。
(2)当定语从句放在主句后面时，as也并非永远等于which。
①当定语从句是否定句或表示否定时只能用which。
He came here very late，which was unexpected.让人没想到的是，他到的非常晚。
②当as在从句中作主语时，后面常接动词的被动语态，如：be known，be said，be reported，be announced等。
如果从句中的动词是主动语态，一般用which作主语。

语法精讲精练非限制性定语从句选修7 unit 5【基本用法】定语从句有限制性和非限制性两种。
1）限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开。
例如：This is the house which we bought last month. 这是我们上个月买的那幢房子。
(限制性) The house, which we bought last month, is very nice.这幢房子很漂亮,是我们上个月买的。
(非限制性)2)当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的。
例如：Charles Smith, who was my former teacher, retired last year. 查理•史密斯去年退休了,他曾My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着This novel, which I have read three times, is very touching. 这本小说很动人,我已经读了三遍。
3)非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。
例如：He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思,这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发。
注：关系代词that和关系副词why不能引导非限制性定语从句。

例11.The settlement is home to nearly 1,000 people, many of left their village homes for a better life in the city. A．whom B．which C．them D．those【解析】由many之后的逗号和选项特征，此处是主从句关系，排除C、D项。

因此选择A。
