Section Ⅳ;非限制性定语从句;一、非限制性定语从句的概念 非限制性定语从句的作用是对所修饰的成分做进一步说明，通常和主句间用逗号隔开。;He often comes to school late, which makes his teacher angry. 他经常上课迟到，这使得他的老师很生气。 She eats too much, which makes her heavier and heavier. 她吃得太多，这使她越来越胖。;二、引导非限制性定语从句的关系代词有 as, which, whom, who, whose；关系副词有 when, where 等。 Yao Ming, as you know, is an excellent basketball player. 你知道，姚明是一名优秀的篮球运动员。 Mr. Smith, whose foot was badly hurt, was quickly sent to the local hospital. 史密斯先生的脚受了重伤，很快就被送到了当地医院。 Well graduate in July, when we will be free. 我们将于七月份毕业，到那时我们就自由了。;[考题印证1];1－2(2012·浙江高考)Ellen was a painter of birds and of nature, ________， for some reason, had withdrawn from all human society. A．which B．who C．where D．whom 解析：选　考查定语从句。分析句子结构可知，此处考查定语从句，定语从句的先行词是a painter，关系词在定语从句中作主语，应该用关系代词who。;1．as 与 which 引导非限制性定语从句时的区别;2．as 引导限制性定语从句，常与 the same, such, as 等连用， 在句中常作主语、宾语或表语。 3．as 引导非限制性定语从句，常用在一些固定结构中。 as is said above 如上所述 as is already mentioned above 就跟上边所提到的那样 as is known to all 众所周知 as is often the case 就跟经常的情况那样 as often happens 就跟经常发生的那样 as is reported 就跟所报道的那样 as you can see 就跟你看到的那样;[考题印证2];2－2(2012·安徽高考)A lot of language learning, ________ has been discovered, is happening in the first year of life, so parents should talk much to their children during that period. A．as B．it C．which D．this;解析：选　考查定语从句。句意：正如发现的那样，大量的语言学习是在出生后的第一年发生的，所以父母应当在那一时期多和孩子说话。分析句子结构可知，“________ has been discovered”，为非限制性定语从句，且位于先行词所指的“A lot of language learning is happening in the first year of life”整个句子之间，故用as。;三、“介词＋关系代词”引导的非限制性定语从句 1．“介词＋关系代词”可以引导限制性定语从句，也可以引导 非限制性定语从句。该结构中关系代词指人时用whom，指物时用which，不可用that；关系代词在从句中作定语时用whose。 I had told them the reason, for which I didnt attend the meeting. 我没有去开会，我已经把理由告诉他们了。 He bought the car for more than $20,000, with which his father was very angry. 他花两万多美元买了这辆车，他父亲对此很生气。;2．from where也可以引导定语从句。 We stood at the top of the hill, from where we can see the whole town. 我们站在山顶上，从那里可以看到整个城镇。;[考题印证3];3－2(2011·浙江高考)English is a language shared by several
