1、Unit 3Looking good,feeling goodNon-restrictive attributive clauses&Question tags1.定语从句(attributive clauses)通常由关系代词或关系副词引出。常见的关系代词有：which(指物)，that(既可指人又可指物)，who(指人，在定语从句中作主语或宾语)，whom(指人，在定语从句中作宾语)，whose(指人或物，作定语)等。关系副词有:when(指时间)，where(指地点)，why(指原因)等。2.定语从句分为限制性定语从句(restrictive)和非限制性定语从句(non-restrict
2、ive)两种。限制性定语从句紧跟先行词，与先行词之间一般不加逗号；非限制性定语从句与主句之间通常用逗号分开。1.My mother,who you met last year,keeps telling me not to take them because they are dangerous.2.Im taking weight-loss pills called Fat-Less,which are quite popular among young women here.Non-restrictive attributive clauses:3.My mother insisted o

6、类Conclusion 21.限制性定语从句与先行词关系密切，是先行词不可缺少的部分，如果去掉它，主句意思往往不明确。2.非限制性定语从句是对先行词的补充或说明，去掉它也不会影响主句的意思。1.This is the house(which/that)we bought last month.这是我们上个月买的那幢房子。2.The house,which we bought last month,is very nice.这房子很漂亮，是我们上个月买的。Example 3限制性定语从句非限制性定语从句3.He seems not to have grasped what I meant,whi
7、ch greatly upsets me.他似乎没领会我的意思，这使我心烦。非限制性定语从句Conclusion 31.限制性定语从句可以由关系代词，关系副词来引导，关系代词作宾语时可以省略。2.非限制性定语从句既可修饰先行词，又可修饰整个主句，不可用that引导且关系代词不可以省略。1.The famous basketball star,_ comes from America,will visit our school soon.2.In those days,she used to go to Mr black,with _ she had a wonderful time.3.I b

9、l know,he is good at English.Aswhich非限制性定语从句考点归纳：I.as和which引导非限制性定语从句，代替整个主句。1.As everyone knows,China is a country with a long history.众所周知，中国是一个历史悠久的国家。Example:2.She is a teacher,as is clear from her manner.她是个教师，这一点从她的举止可以清楚地看出。3.He missed the show,which was really a great pity.他错过了演出，这真是很大的遗憾。Co
10、nclusion1.as 和which在引导非限制性定语从句时，as和which可代替整个主句，相当于and this或and that。这两个关系代词都可指代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。2.as和which引导非限制性定语从句的不同之处在于：(1)as 引导的定语从句可置于句首，而which引导的定语从句不可放在句首。(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；若从句中的谓语为行为动词，则从句的关系代词只能用which。另外，as引导非限制性从句，常带有“正如”的意思。1.Alice received an invitation f

13、此时先行词在其后的定语从句中作介词的宾语，关系代词不可用that。如先行词指人则用whom，如先行词指物则用which引导从句。1.Many students in this school,some of which are not overweight,are going on diets.2.There are 54 students in my class and ten of whom come from US.whomCorrection:them3.Half a million pairs of shoes are produced by the workers here ever
