3、 same.as that of which the sth.such.as 2.关系副词 relative adverb when,where,why the way(_/that/in which)I didnt like the way(_/that/in which)he spoke.,连词（关系词）,关系代词引导的定语从句,1）who,whom,that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下：Ishethemanwho/thatwantstoseeyou?他就是你想见的人吗？（who/that在从句中作主语）Heisthemanwhom/thatIsawyeste

4、rday.他就是我昨天见的那个人。（whom/that在从句中作宾语）,2)Whose 用来指人或物，(只用作定语,若指物，它还可以同ofwhich互换）,例如：Theyrushedovertohelpthemanwhosecarhadbrokendown.那人车坏了，大家都跑过去帮忙。Pleasepassmethebookwhose(ofwhich)coverisgreen.请递给我那本绿皮的书。,3）which,that它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：Aprosperitywhich/thathadneverbeenseenbeforeappearsi

8、词则要求用关系副词。准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。,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：Thisisthehousewhichweboughtlastmonth.这是我们上个月买的那幢房子。（限制性）Thehouse,whichweboughtlastmonth,isverynice.这幢房子很漂亮，是我们上个月买的。（非限制性）,II.限制性和非限制性定语从句,2.当先行词是专有名词或物主代词和指示代词所
