28、swered the questions wassurprising.,I dont like the way(that/in which)you laugh at her.,（四）关系代词与关系副词的选择,用关系代词还是关系副词引导定语从句主要看关系词在定语从句中的作用（即所担当的成分）.,A.I know a place _we can have a picnic.,I know a place _is famous for its beautiful natural scenery.,Compare:,B.I will never forget the days _we spent ou

29、r holidays together.,I will never forget the days _ we spenttogether.,C.This is the reason _ he was dismissed.,This is the reason _ he explained to me forhis not attending the meeting.,（五）but 有时也用作关系词引导定语从句。,There are very few but admire his talents.,（but=who dont）,（六）定语从句与同位语从句的区别,1定语从句修饰限定先行词，它与先行

30、词是修饰关系；同位语从句说明先行词的具体内容，它与先行词是同位关系。,The plane that has just taken off is for Paris.,The fact that he has already died is quite clear.,2定语从句由关系代词或关系副词引导，关系词在从句中担当相应的句子成分，关系代词在从句中作宾语时经常可省略。,同位语从句主要由连词that引导，在从句中一般不担当成分；有时也由where,when,how,who,whether,what等连词引导，这些连词则在从句中担当成分。,The news that he told me is
