判断关系代词与关系副词方法一: 用关系代词,还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语,就必须要 求用关系代词。例如:(错) This is the mountain village where I visited last year.(错) I will never forget the days when I spent in the countryside.(对) This is the mountain village (which) I visited last year.(对) I'll never forget the days (which) I spent in the countryside.习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。方法二: 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.先行词在从句中作主、定、宾语时,应选择关系代词;先行词在从句中作状语时,应选择关系副词。例如:(对)Is this the museum which you visited a few days ago?(对)Is this the museum where the exhibition was held?定语从句=先行词+关系词+从句指被定语从句修饰的名词、代词。一般先行词出现在定语从句的前面。关系词常有3个作用:①连接作用,连接主句和定语从句。②指代先行词。③在定语从句中担当成分。注:关系代词有主语、宾语、定语之分。一般who做主语或其宾格形式的whom做宾语(whom作宾语时可省略),whose作为定语(whose不可省略)。
