易混易错定语从句例析 有些定语从句方面的例题，如果不仔细审题、不弄清句意和句子结构，就很可能把一些似是而非的东西搞混，从而降低解题的准确性。要想解决这个问题就得从准确理解句意和理清句子结构入手。1Who lives in the house windows face south？ Who lives in the house the windows face south？Awhose Bwhich C of which Dthat解析：答案是AC。在句中 windows 前没有定冠词，它所缺的是定语形容词，而whose 的用法就是在定语从句中作定语且既可指人也可指物。在句中 windows 前有定冠词，所以要填的内容不能作前置定语，又因为“房子的窗户”用英语表达是“the windows of the house”，故可用 of which 引导定语从句。2Is this factory you visited last year？Is this the factory you visited last year？Athat B of which Cthe one D where解析：答案是CA。在句中 factory 前没有定冠词，这说明 this 是作它的定语。这样，句中就缺少表语，也就是说定语从句缺少先行词，故选 C（the one 后省略了 that）。在句中 this 作主语， the factory 作表语，其后带一个 that 引导的定语从句，故选 A。3John is the only one of the students whoFrenchJohn is one of the students who FrenchAknow Bknows C knowing D known解析：答案是BA。在句中的句意是“约翰是学生中唯一懂法语的那个学生”，其重心是 the only one 故从句谓语动词应与 one 一致。在句中的句意是“约翰是懂法语的学生中的一个”，也就是“ 懂法语的学生不止一个，约翰只是其中之一”，其重心是 the students，故从句中谓语动词应与 students 一致。4When I have trouble，he is the only one I can ask for helpWhen I have trouble，he is the only one I can go for helpAwhom Bto whom Cwhich Dto who解析：答案是AB。句中，在结构上所要添的内容在从句中作 ask 的宾语其句式是ask sbfor sth，故用 whom 引导定语从句。在句中， go 是不及物动词其句式是 go to sbfor sth，故用 to whom 引导定语从句。5This is the knife I usually cut my pencilThis is the knife I usually use to cut my pencilAwith which Bwhich Cby which Dwith that解析：答案是AB。在句中，定语从句的句式是 cut my pencil with the knife，故用with which 引导定语从句。在句中，定语从句的结构是 use the knife to cut my pencil，故用 which 引导定语从句。6Last summer he went to Beijing， he had visited twiceLast summer he went to Beijing， he visited a lot of places of interestAwhich Bwhere Cthat D there解析：答案是A 或 BB。在句中，所要填的内容在定语从句中应作 visited 的宾语，故应填关系代词 which 或 that。在句中，所要填的内容在定语从句中作地点状语，故应填关系副词 where。7He still remember the days we spent together He still remember the days we spent the summer holidays togetherAwhich Bwhen Cwhere Dthat解析：答案是AB。在句中，所要填的内容在定语从句中应作 spent 的宾语，故应填关系代词 which。在句中，所要填的内容在定语从句中作时间状语，故应填关系副词when。8The reason he gave us was that his car broke down on the wayThe reason he was late was thathis car broke down on the wayAwhy Bwhich Chow Dwhat解析：答案是BA。在句中，所要填的内容在定语从句中应作 gave 的宾语，故应填关系代词 which。在句中，所要填的内容在定语从句中作原因状语，故应填关系副词why。
