人教版英语高三上学期第二轮专题语法复习直击高考---定语从句一、知识扫描：在复合句中修饰某一名词或代词，用做定语的从句叫定语从句。定语从句可分为限制性定语从句和非限制性定语从句两种。定语从句是高考的热点之一，一般放在单选题和短文改错中。考试的重点在关系词的选择、非限制性定语从句、介词家关系代词等方面，并且常常是几个知识点放在一起考查。阅读理解中定语从句的理解也很关键。二、高考热点：1、关系代词 who(m)、which、that 的选用和省略。2、先行词是表示时间或地点的名词时，用关系副词 when，where 还是用关系副词 which ，that。3、介词+关系代词 which, whom 等，不能用 that, who。4、先行词是整个句子或句子的一部分时，用 as 或 which 引导的非限制性定语从句。5、用 Whose 或 of which 引导的定语从句。6、先行词是 the way 或 the reason 时，关系词的选择。7、先行词前有 So ，such， as ，same 等时，用 as 引导定语从句。三、核心解读核心解读一：1、1>关系代词的省略情况That , which, who, whom 做宾语、表语时可省略。He isn’t the man (that) he was.The man (man) I spoke to is my brother.The book (that/which) I borrowed yesterday is very interesting.关系代词在从句中做介词宾语，而介词不在关系代词前时可省略。This is the very book (that/ which) I have been looking for.That 可做关系副词，往往省略，先行词多为 way, day, time, moment 等。I don’t like the way (that=in which) he talks.This is the third time (that) he has been late this week.2>关系代词的选用情况。用于指代先行的名词或名词同等语并兼具连词功能引导从句与先行词之间关系的词叫关系代词.如果一个句子中缺成分<常常是选空后的句子缺主语、宾语或表语等>（一个简单的英语句子至少要有主语和谓语，谓语动词若是及物动词时则必须要有宾语），就要选择关系代词(that, which, as, who, whom, whose)。不缺成分就只能缺句子的壮语,所以就应选择关系副词(when, where, why)。I walked in the yard，____Tom and Jim were tying a big sign onto one of the trees.A. which B. when C. where D. that[点拨]：答案 C。选空后的句子，主语是 Tom and Jim。谓语是 were tying。宾语...
