如果定语从句中缺少主语、宾语，就应考虑使用关系代词。
1.I’llneverforgetthedays when IspentinNewYorkwithyou.（when应改为which或that，spent后面缺少宾语，故用关系代词。
）2.I’llneverforgetthedays which IvisitedNew Yorkwithyou.（which改为when，定语从句中有主语和宾语，故使用关系副词）3.Isthisthelibrary where youvisitedyesterday?（where改为that或which，也可省略，动词visit后缺少宾语，故用关系代词引导定从。
）易错点二：固定句式出差错?4.Maryissolovelyagirl as everybodyloves her.（as改为that;so…that为固定句式，that引导结果状语从句，该从句的成分是完整的，不缺少主语或宾语）5.Maryissolovelyagirl that everybodyloves.（that改为as.so…as是固定搭配，as引导定语从句，as在定语从句中作宾语或主语，类似的固定句式的定从还有thesame…as(that)，such…as，as…as）。
易错点三：主谓不一致?6.Tomisoneofthestudentswho likes swimming.（likes改为like;在“oneof+复数名词+定语从句”结构中，定语从句的先行词是复数名词，故关系代词who=students,是复数概念。
）7.Tomis the onlyoneofthestudentswho like swimming.（like改为likes.在“the(only)oneof+复数名词+定语从句”结构中，先行词是one，而不是复数名词，故关系代词who=one，是单数概念）易错点四：与强调句型及其他句型的混合?8.Wasitintheshop that youboughttherecorderthatyoulostyo urpen?（第一个that改为where，youboughttherecorder 为定语从句，其引导词应用where，后面第二个that才是强调句中的that，此句可还原为：Youlostyourpenintheshopwhereyouboughttherecorde r.）9.You’dbettermakeamark at whereyouhaveanyquestions.（去掉at，where引导地点状语从句）易错点五：特殊名词作先行词时关系词的选取错误?10.Idon’tliketheway which youspeaktoher.（在which前加in，或将which改为that，或去掉which.注意：way 作先行词时，其定从引导词可用that或inwhich或省略）11.Idon’tcareforpay.Ijustwanttogetajob that Icanbegreatlyv alued.（that改为where或inwhich.注意：case,club,job，occasion,point,position,situation，system,等作先行词时，定从常用where或inwhich,但最终决定答案的是看定从中是否缺少主语，宾语。
）易错点六：忽略as和which引导非限定性定语从句的区别?12.Hefailedintheexamagain，which wasexpected.（which 改为as）13.Hefailedintheexamagain，as wasnotwhathehadexpected.（as应改为which）as和which虽然都可引导非限制性定语从句，但仍有以下三点区别：(1)as有“正如;就像”之意，而which 没有;(2)as引导的非限制性定语从句可置于句首、句中或句末，而which只能置于句末;(3)如果非限制性定语从句是否定句时，只能用which引导。
易错点七：忽略that和which引导限制性定语从句的区别?14.Thisisthemostexcitingfootballgame which Ihaveeversee n.（which改为that）15.Herearethesamples that—hadIthoughtofit—youcouldh avetakenwithyouyesterday.（that改为which）析：当先行词被最高级、序数词修饰或先行词本身是不定代词(且指代物)时，只能用that来引导定语从句，当关系词后面有插入成分时，只能用which来引导定语从句易错点八：介词前置出差错?16.Thetwothings with whichMarxwasnotsurewerethegram marandsomeoftheidioms.（with改为about或of.在定语从句中前置的介词必须和后面的动词或形容词构成固定搭配）17.Tellhimallthethingstowhichheshouldpayattention.（把to移到attention的后面。
并不是所有的固定搭配中的介词都可前置）易错点九：which和whose的意义不明确?18.Thebook which coverisbrokenisofgreathelptoallofus.（which改为whose）19.Thebookof whose thecoverisbrokenisofgreathelptoallof us.（whose改为which）析：关系代词which不能在定语从句中作定语，但whose可作定语，“whose+n”相当于“the+n+ofwhich”或“ofwhich+the+n”。

如表时间的先行词不一定用when，表地点的先行词不一定用where，表原因的先行词不一定用why/forwhich等。
?①Isthisthereason________atthemeetingforhiscarelessnessinhiswork??A.heexplainedB.whatheexplained?C.howheexplainedD.whyheexplained?②Thisisjusttheplace________Iamlongingtovisittheseyears.?A.thatB.where?C.inwhichD.towhich?句①中reason作explain的宾语，可以省略引导词，所以选A，对原因进行解释的内容在句子后面forhiscarelessnessinhiswork。
句②中place作宾语从句的宾语，所以选A。
?2.因为句子中有插入语或先行词另有限定语等搞不清楚先行词而出错。
?①Heoftenhelpsthestudents________hethinksarenotquickattheirstudies.?A.whomB.whoC.whenD.because?②Sheisoneofthegirlswho________passedtheexam.Sheistheonlyoneofthegirlswho_ ________passedtheexam.?A.wasB.wereC.hasD.have?句①中hethinks作插入语，先行词是students,定语从句中缺少主语,所以B正确。
?句②中第一句中的who指代girls,是复数；而第二句中的who则指代theonlyone，所以是单数，所以正确答案分别为D，C。
