13、s stands for what is right.热点语法定语从句是高中阶段的重要语法之一。定语从句在英语中的普遍运用，使得掌握其用法非常必要。本模块主要从以下几个方面复习了定语从句的用法：关系代词和关系副词引导定语从句的区别；介词前置的现象；非限制性定语从句。*关系代词和关系副词引导定语从句的区别 关系代词在定语从句中可充当主语、宾语或定语，而关系副词则只能充当状语，因此，判断定语从句中缺少何种成分，是决定选用关系代词或关系副词的重要依据。（1）a. He still remembers the days _ he spent with his grandparents in the d

14、istant village. b. He still remembers the days _ he worked with his grandparents in the distant village. A. which/that B. when 解析：上面a句中，定语从句中spent缺少宾语，因此应选择答案A；而b句中，定语从句中不缺主语或宾语成分，故选择B项，when 充当句中的时间状语。提示：决定定语从句由关系代词或关系副词引导的关键不在于先行词，而在于从句中缺少何种成分。 *介词前置的现象当定语从句中存在介词时，为了使定语从句与主句的联系更紧密，通常将介词提到引导词之前，即构成介

15、词前置。介词前置应注意的问题有：a. 一旦介词前置，关系代词只能由whom或which中选择：指人用whom；指物用which。不能使用that, 且关系代词也不能省略。如： Do you know the person to whom our teacher was just speaking? This is the very room in which Karl Marx was born.b. 若定语从句中的介词属于结构紧凑的固定搭配，则一般不能前置，以免引起歧义。如： Is this baby the one who you were looking after the whole

16、morning? 此句不可说成：Is this baby the one after whom you were looking the whole morning? c. “介词+关系代词”通常可与关系副词相互转化。如： This is the very room in which Karl Marx was born. = This is the very room where Karl Marx was born.提示：定语从句中介词的选择应取决于从句中的动词，或看介词与先行词的关系而定： *非限制性定语从句定语从句分为限制性定语从句和非限制性定语从句两种。非限制性定语从句与主句的关系较

17、限制性定语从句更松散，常表示并列的意思。其区别于限制性定语从句的标志是主句和从句之间有逗号分隔开，而限制性定语从句则无此标志。另外，在所有的限制性定语从句的引导词中，只有that不能引导非限制性定语从句，其他的均可。在考查非限制性定语从句时，常常考查的是which和as 的区别。请看： as引导非限制性定语从句时，从句既可放在主句之前，又可放在主句之后，而which引导非限制性定语的从句只能放在主句之后。如：As is known to all, the 2008 Olympic Games will be held in Beijing.The sports meeting was put off because of the heavy rain, which made us very disappointed. 在非限制性定语从句中，关系代词as作
