一、 关系代词和关系副词的区别1、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。例 1. Is he the man who/that wants to see you?(who / that 在从句中作主语,指人)例 2. He is the man whom/ that I saw yesterday.(whom / that 在从句中作宾语,指人)例 3. They rushed over to help the man whose car had broken down。(whose 在句中作定语,指人)例 4. Please pass me the book whose cover is green。(whose 在句中作定语,指物。)2、关系副词(when, where, why,)可代替的先行词是时间、地点或原因的名词,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。例 5。 Beijing is the place where (in which ) I was born. 例 6。 Is this the reason why (for which ) he refused our offer? 例 7。 His father died the year (when / in which ) he was born。 例 8。 He can't find the place (where / in which ) he lived forty years ago。二、推断用关系代词和关系副词用关系代词,还是关系副词完全取决于从句中的谓语动词。缺少宾语,就必须要求用关系代词;不缺成分(作状语)用关系副词。(推断对错)1. This is the mountain village where I visited last year。2。 I will never forget the days when I spent in the countryside。例 9. This is the museum ____ the exhibition was held.
