.Unit 9語法導(dǎo)學(xué)案:定語從句專題講解1、 基本概念:在復(fù)合句中,修飾某一名詞或代詞的從句叫定語從句。Doyouknowthemanwhospokeatthemeetingjustnow?Thatisthehousewherehelivedtenyearsago.定語從句所修飾的詞叫先行詞;定語從句一般用關(guān)系代詞或關(guān)系副詞來引導(dǎo),關(guān)系詞放在先行詞與定語從句之間起連接作用,同時又作從句中的一個成分。引導(dǎo)定語從句的關(guān)系代詞有:that,who,whom,whose,which,as關(guān)系副詞有:when,where,why.二、定語從句的關(guān)系詞 引導(dǎo)定語從句的關(guān)系詞有關(guān)系代詞和關(guān)系副詞,常見的關(guān)系代詞包括that,which,who(賓格whom,所有格whose)等,關(guān)系副詞包括where,when,why等。關(guān)系代詞和關(guān)系副詞放在先行詞及定語從句之間起連接作用,同時又作定語從句的重要成分。定語從句的謂語動詞由先行詞來決定。三、定語從句的分類 根據(jù)定語從句與先行詞的關(guān)系,定語從句可分為限制性定語從句及非限制性定語從句。限制性定語從句緊跟先行詞,主句與從句不用逗號分開,從句不可省去,非限制性定語從句主句與從句之間有逗號分開,起補充說明作用,如省去,意思仍完整。四、關(guān)系代詞的用法關(guān)系代詞指代在定語從句中的作用that既指人,也指物主語、賓語which指物(相當(dāng)于that)主語、賓語who指人(相當(dāng)于that)主語whom指人賓語whose既指人,也指物定語 1. that 既可以用于指人,也可以用于指物。在從句中作主語或賓語,作主語時不可省略,作賓語可省略。例如: Mary likes music that is quiet and gentle.瑪麗喜歡輕柔的音樂。(that作主語) The coat (that) I put on the desk is blue.我放在桌子上的那件外套是藍(lán)色的。(that作賓語) 2.which用于指物,在句中作主語或賓語,作主語不可省略,作賓語可省略。例如: The building which stands near the train station is a supermarket.位于火車站附近的那 座大樓是一家超市。(作主語) The film (which) we saw last night was wonderful. 我們昨天晚上看的那部電影很好看。(作賓語) 3.who,whom用于指人,who 用作主語,whom用作賓語。在口語中,有時可用who代替whom, 也可省略。例如: The girl who often helps me with my English is from England.經(jīng)常在英語方面幫助我的那個女孩是英國人。(作主語) Who is the teacher (whom) Li Ming is talking to?正在與李明談話的老師是誰?(作賓語)注意: (1)當(dāng)定語從句中含有介詞,介詞放在句末時,who,that,which可省略,但介詞在關(guān)系代詞前時,只能用“介詞+which/whom”結(jié)構(gòu)。例如: This is the house in which we lived last year.這是我們?nèi)ツ昃幼〉姆孔印?Please tell me from whom you borrowed the English novel.請告訴我你從誰那借的這本英文小說。 (2)含有介詞的固定動詞詞組中,介詞不可前置,只能放在原來的位置上。例如: This is the person whom you are looking for. 這就是你要找的那個人。 (3)that 作介詞的賓語時,介詞不能放它的前面,只能放在從句中動詞的后面。例如: The city that she lives in is very far away.她居住的城市非常遠(yuǎn)。 (4)關(guān)系詞只能用that的情況: a. 先行詞被序數(shù)詞或形容詞最高級所修飾,或本身是序數(shù)詞、基數(shù)詞、形容詞最高級時,只能用that,而不用which.例如: He was the first person that passed the exam. 他是第一個通過考試的人。 b.被修飾的先行詞為all, any, much, many, everything, anything, none, the one等不定代詞時,只能用that,而不用which.例如: Is there anything that you want to buy in the shop? 你在商店里有什么東西要買嗎? c.先行詞被the only, the very, the same, the last, little, few 等詞修飾時,只能用that,而不用which.例如: This is the same bike that I lost.這就是我丟的那輛自行車。 d. 先行詞里同時含有人或物時,只能用that, 而不用which.例如: I can remember well the persons and some pictures that I saw in the room.我能清楚記得我在那個房間所見到的人和一些照片。 e.以who或which引導(dǎo)的特殊疑問句,為避免重復(fù),只能用that.例如: Who is the girl that is crying? 正在哭泣的那個女孩是誰? f.主句是there be 結(jié)構(gòu),修飾主語的定語從句用that,而不用which.例如: There is a book on the desk that belongs to Tom. 桌子上那本書是湯姆的。 (5)關(guān)系詞只能用which,而不用that 的情況: a.先行詞為that, those時,用which, 而不用that.例如: Whats that which is under the desk? 在桌子底下的那些東西是什么? b.關(guān)系代詞前有介詞時,一般用which,而不用that.例如: This is the room in which he lives. 這是他居住的房間。 c.引導(dǎo)非限制性定語從句,用which, 而不用that.例如: Tom came back, which made us happy. 湯姆回來了,這使我們很高興。五、關(guān)系副詞的用法(1)when指時間,其先行詞表示時間,在句中作時間狀語。它的先行詞通常有:time,day,morning,night,week,year等例如:This was the time when he arrived.這是他到達(dá)的時間。(2)where指地點,其先行詞表示地點,在句中作地點狀語。它的先行詞常有:place,spot,street,house,room,city,town,country等。例如:This is place where he works.這是他工作的地點。注意:先行詞表示地點,不一定都用Where引導(dǎo)定語從句 一般來說,英語學(xué)習(xí)者的腦海中會形成這樣一個概念:在定語從句中,如果先行詞是表示地點的名詞(如place等),就用關(guān)系副詞where引導(dǎo)定語從句。這種想法是錯誤的。如果定語從句不缺少主語或賓語,而是缺少地點狀語,便用where來引導(dǎo);如果定語從句不缺少狀語,而是缺少主語或賓語,則要用關(guān)系代詞(which或that)來引導(dǎo),以補足定語從句中所缺失的主語或賓語如1.Inanhour,wecantraveltoplaces_wouldhavetakenourancestorsdaystoreach.A.whereB.whenC.whichD.what2.Thisisthetown_Iwantedtovisitmost.A.whereB.whenC.thatD.what3.Thisisthetown_Iwasborn.A.whereB.whenC.whichD.what4.Ive neverbeentoBeijing,butitstheplace_.A.whereIdliketovisit B.inwhichIdliketovisit C.Imostwanttovisit D.thatIwanttovisititmost(3)why 指原因,其先行詞是原因,起原因狀語作用。它的先行詞只有reason。例如:Nobody knows the reason why he is often late for school. 沒人知道他為什么上學(xué)總遲到。1這三個關(guān)系副詞在意義上都相當(dāng)于一定的介詞+which結(jié)構(gòu):when=on(in,at,during.)+which;where=in (at,o.)+which;why=forwhich.例如:IwasinBeijingonthedaywhen(=onwhich)hearrived.Theofficewhere(=inwhich)heworksisonthethirdfloor.Thisisthechief reasonwhy(=forwhich)wedidit.練習(xí)題I.單項填空1. -Do you know the man _is talking with your father? -Yes, hes our headmaster.
