三 : 考查定语从句
定语从句一直是高考测试的重点和热点，关系词是用在定语从句中来代替先行词的,选择关系词的关键是看先行词在定语从句中作何成分。作主语、宾语或表语时,用关系代词,指人用who (宾格用whom)或that,指物用which或that;如果作状语,则选用关系副词,分别用when, where, why代替时间、地点、原因状语;如果先行词在定语从句中作定语,则不管指人还是指物,都可用whose。但这里特别需要注意两个问题：1.“介词＋关系代词”介词的选择，在教学中要引导学生如何找介词，告诉学生如何去找介词，而介词的选择涉及到介词与先行词之间的关系以及介词与动词的一些固定搭配，介词后面的关系代词只能用which或whom。当先行词是“物”时，介词后面的关系代词用which；当先行词是“人”时，介词后面的关系代词用whom。2.当先行词是时间、地点名词时，学生容易犯固定思维，一看到时间名词就选择when,一看到地点名词就选择where。我们首先必须判断要选择的关系代词在句子中到底作什么成分，如果是作状语，就选择when,where或“介词+关系代词” ；如果是作主语、表语或宾语，就应选择which，that .
