关系代词在从句中作主语或宾语，关系副词在句中作状语。在句子中作定语修饰名词或代词的从句，这种从句有关系代词或关系副词引导并作句子成分，定语从句从句还叫做嵌入句，因形容词定语，所以又称之为形容词性从句。定语从句的位置通常是在先行词后。  关系代词（that, who, whom, whose, which）所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。 1.Is he the man who/that wants to see you?（who / that在从句中作主语，指人） 2.He is the man whom/ that I saw yesterday.（whom / that在从句中作宾语，指人） 3.They rushed over to help the man whose car had broken down.（whose在句中作定语，指人） 4.Please pass me the book whose (of which) cover is green.（whose在句中作定语，指物。若指物，它还可以同of which互换） 5.The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作carry的宾语，指物） 关系副词（when, where, why, that）可代替的先行词是时间、地点或理由的名词，在从句中作状语。关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用。 6.Beijing is the place where (in which) I was born. 7.Is this the reason why (for which) he refused our offer? 8.His father died the year (that / when / in which) he was born. 9.He can’t find the place (that / where / in which) he lived forty years ago.
