1、定语从句难点透视定语从句的引导词分为关系代词（who,whom,whose,which,that）和关系副词（where,when,why）两类，这些引导词在引导定语从句的同时均在从句中充当成分。关系代词可作主语、宾语和定语，作宾语时可省略；关系副词可作状语，一般不能省略。下面简单介绍一下定语从句的难点。一、介词（短语）+关系代词/副词 1.此处关系代词只能是which/whom/whose/where/when，而不能用who/that。如： Theyarrivedatanoldbuilding,inf

5、限制性定语从句。如： Heturnedouttobeagreatsuccessasadancer,whichwasmorethanwecouldexpect. Asisknowntoall,MadameCurieisthefirstwomanscientistintheworldtohavewontwoNobelPrizes. HaveyouboughtthesamedictionaryasIreferredtoyesterday?四、非地点名词作先行词时用where引导定语从句的特例 通常先行词是地点
6、名词，且定语从句的引导词在从句中作地点状语时，用where引导定语从句，但有时先行词是非地点名词时，也须用where引导定语从句，表示抽象意义的一种状态，此类词包括point,situation,case等。如： Thetreatmentwillcontinuetillthepatientreachthepointwherehecanwalkcorrectlyandsafely.(point意为“程度”) Canyouthinkofasituationwherethisidiomcanbeused?(situa
7、tion意为“情景”) There’realwayscaseswherenon?鄄nativeEnglishspeakerscan’tmakethemselvesunderstoodjustbecauseoftheirlackofculturebackgroundofthevisitedcountries.(case意为“情形，情况”)五、way和time作先行词时的情况 1.way作先行词，意为“方式、方法”时，引导词在从句中作状语，可用that/inwhich引导，也可省略；若引导词作从句的主语或宾语，用t
8、hat/which引导，引导词作宾语时可省略。如： I’vethoughtofagoodway(that/inwhich)wecanconducttheexperimentsuccessfully.Thewaythat/whichwillbeusedtocarryouttheoperationwassuggestedby
