【正文】 a man who is talking happily．(誤)I have many collections of stamps, and some of which are my favorite．第一句中關系代詞as代替逗號后面的整個主句，因此主句是不需要連接詞的。　　易錯聚焦 (一)定語從句意識缺失1．關系代詞被普通代詞取代(誤)I have many collections of stamps, some of them are my favorite．(正)I have many collections of stamps, some of which are my favorite．2．關系代詞遺漏(誤)The last one leaves the classroom please close the windows．(正)The last one who leaves the classroom please close the windows．第一句從漢語意思角度是對的，但是漢語的干擾破壞了英語句式結構。但還要注意看定語從句是否缺主語、賓語或表語，如果不缺這三種句子成分，則不用as。6．如果先行詞指人，“介詞＋關系代詞”引導的定語從句中的關系詞用whom；如果先行詞指物，“介詞＋關系代詞”引導的定語從句中的關系詞用which。4．如果先行詞指時間或地點，定語從句中缺少時間狀語或地點狀語，定語從句中用when/where；如果從句中缺少的是主語或賓語，則用that/which。2．如果先行詞指人，定語從句中缺少賓語，限制性定語從句中用who/that/whom；非限制性定語從句中用whom；缺少表語，限制性定語從句用that；非限制性定語從句用who。clock．(when引導時間狀語從句)定語從句與狀語從句when，where和why在引導定語從句時可以用“介詞＋which”的結構來替換，在引導狀語從句時則不行 This is the school where(＝in which)I once worked．(where引導定語從句)Put back the book where it was．(where引導狀語從句)定語從句中的關系代詞在從句中充當某種句子成分，因此去掉之后從句成分不完整；而狀語從句中的連接詞在從句中不作任何成分，去掉后從句的成分仍然完整　　It is such an interesting book as we all like．(as引導定語從句，作動詞like的賓語)It is such an interesting book that we all like it．(that引導結果狀語從句，不充當從句的成分)定語從句與同位語從句定語從句在復合句中相當于形容詞，對先行詞起修飾或限制的作用，與先行詞之間有從屬關系。并列句中絕對不可再用引導定語從句的關系詞1．I have three cars，none of________ is in good condition．2．I have three cars，but none of ________ is in good condition．句1中cars后面是非限制性定語從句，空格中填關系代詞which；句2中有并列連詞but，題干是并列句，空格中填代詞them。 There was a time when/during which there were no radios or TV sets．曾經有一段時間既沒有收音機也沒有電視機。難點二　先行詞是time時，關系詞的選用先行詞是time時，如果time作“次數(shù)”講，應當用關系代詞that來引導定語從句；time作“時刻”“一段時間”講時，若關系詞在從句中作狀語，則用關系副詞when或at/in/during which，若關系詞在從句中作主語、賓語等，則用that/which。試比較：It must be the way(that/in which) you write that leads to your ugly handwriting．一定是你寫字的方式導致了你難看的書寫。He is one of the students who have made great progress．他是取得很大進步的學生之一。The recorder that has been given to me is homemade．給我的那臺錄音機是國產的。I would like to use the same tool that you used yesterday．我想用你昨天使用的那件工具。5．“the same．．．that．．．”表同一個人或物，而“the same．．．as．．．”表同種類的東西。4．“such/so．．．as．．．”表“像……這樣……”的意思，用來引導定語從句，as在從句中充當主語、賓語或表語等。as (it) often happens，as I remember，as is often the case，as is expected，as is known to us，as is shown等。s longheld dreams e true．莫言被授予2012年諾貝爾文學獎，這使中國人長久以來擁有的夢想之一變成現(xiàn)實。2．which引導定語從句代指前面整句話內容時，意為“這，這一點”。(from where相當于from out of the window，而不是from the window) 考點五as，which引導的定語從句1．as作關系代詞用來引導非限制性定語從句，代指整句話(或一部分)內容，意為“正如，正像”，as引導的句子可放在句首、句末或句中。3．有時“介詞＋where”可以引導定語從句，此時要和“介詞＋which”引導的定語從句從意思上加以區(qū)別。在some，any，few，none，all，both，neither，most，each等代詞或數(shù)詞的前、后可以用of which/whom。ll never forget the time during which I spent my childhood in the country．我永遠不會忘記孩童時代我在鄉(xiāng)村度過的時光。 考點四“介詞＋關系詞”引導的定語從句1．一般來說，確定關系代詞前的介詞，可以從以下三方面入手：①先行詞的意義；②從句中的動詞或形容詞與先行詞的固定搭配；③句子的意思。The reason why he didn39。3．關系副詞why引導的定語從句關系副詞why引導定語從句時，修飾表示原因的名詞。It39。(2)有時先行詞是表示抽象意義的地點名詞，像activity，business，career，case，job，point，position，race，stage，situation等，當從句中缺少狀語時，用關系副詞where。2．關系副詞where引導的定語從句(1)先行詞是表示地點的名詞時，從句中不缺少主語、賓語或表語，引導詞常用關系副詞where，where在從句中充當?shù)攸c狀語。The book was written in 1946，since when the education system has witnessed great changes．這本書寫于1946年。I still remember the day when I first came to this school．我還記得我第一次來這所學校的那天。What39。Do you know the things and persons that they are talking abou
