【正文】 taken care 、關(guān)系副詞引導(dǎo)的定語從句*when：當(dāng)主句中的先行詞(即主句中被后面定語從句修飾的詞)是表示時(shí)間意義的名詞時(shí)，它只能作定語從句的時(shí)間狀語，放在定語從句句首。He did very well in the petition, which made his parents very happy.* 關(guān)系代詞 whom，which 在定語從句中作介詞賓語時(shí)，可以和介詞一起放于先行詞與定語從句之間，有時(shí)為了關(guān)系緊湊也可以將 whom 與 which 與先行詞緊挨著書寫，的工廠。（非限)There is somebody here who wants to speak to you這里有人要和你說話(限制性)* 4)which還有一種特殊用法，它可以引導(dǎo)從句修飾前面的整個(gè)主句，代替主句所表示的整體概念或部分概念。 necklace, which you gave me as a present, was lost has a daughter, who works in a hospital.* 3)先行詞本身是that時(shí)； clock is that which tells the time 非限定性定語從句的作用是對(duì)所修飾的成分作進(jìn)一步說明，通常是引導(dǎo)詞和先行詞之間用逗號(hào)隔開，將從句拿掉后其他部分仍可成立。例如： The writer and his novel that you have just talked about are really well 。* 4）當(dāng)主句以who或which開頭時(shí)，定語從句中引導(dǎo)詞用that ,不用which 或 who，以避免重復(fù)。例如： My necklace is not the only thing that39。The first thing that we should do is to get some 。* 2）當(dāng)先行詞被形容詞的最高級(jí)或序數(shù)詞修飾時(shí)。(1)The people that/who e to visit the city are all here.(在句子中做主語)(2)Where is the man（that/whom）I saw this morning?(在句子中做賓語)* ，也可指物，在定語從句中做定語(1)He has a friend whose father is a doctor.(2)I lived in a house whose roof has fallen ，常用以下結(jié)構(gòu)來代替(3)The classroom whose door is broken will soon be repaired.=The classroom the door of which is broken will soon be repaired.(4)Do you like the book whose color is yellow? =Do you like the book the color of which is yellow? * 具體使用時(shí)還要注意下列問題：只能使用that,不用which 的情況：* 1）當(dāng)先行詞是：all , any , anything , everything , nothing或被它們修飾時(shí)。(1) is the person(whom)you talked ：關(guān)系代詞whom在口語和非正式語體中常用who代替，可省略。如：1)The man who lives next to us is a )You must do everything that I ，叫先行詞，定語從句放在先行詞的后面。ll buy the same coat ________ you made another wonderful discovery, ________ of great importance to I think is I think it is I think it think is is known to everybody, the moon travels round the earth once every is the first time ________ he has been which don39。ve never heard so interesting a story ________ you told which which 39。s D that may have missed her train, in ____ case she won39。定語從句專項(xiàng)練習(xí) are three bedrooms in the house,_____ is Mary39。若定語從句中缺主語或賓語，用that/which引導(dǎo)定語從句,作賓語時(shí)可以省略。用that引導(dǎo)定語從句指同一物，而用as引導(dǎo)定語從句指同類事物。如： Tom was late for school again and again, which made his teacher very tables are made of metal, which made them very , so, the same修飾時(shí)，關(guān)系詞常用as。另外，as 常常有“正如、正像”的含義。 引導(dǎo)的非限制性定語從句可以放在主句之前、主句之后，甚至還可以分割主句。如： He married her, as / which was ，這是很自然的事。七、關(guān)系代詞as和which 引導(dǎo)的定語從句as 和which 引導(dǎo)非限制性定語從句時(shí)，其用法有相同之處，也有不同之處。ll never forget the days when I worked together with is the mountain village _______I visited last year.(which or where)I will never forget the days _______ I spent in the countryside.(which or when)方法二： 準(zhǔn)確判斷先行詞在定語從句中的成分(主、賓、定、狀)，也能正確選擇出關(guān)系代詞/關(guān)系副詞。不及物動(dòng)詞后面無賓語，就必須要求用關(guān)系副詞或者是介詞加關(guān)系代詞；而及物動(dòng)詞后接賓語，則要求用關(guān)系代詞。This is the cage that / which Polly lives in.= This is the cage in which(where)Polly clock is that which tells the 。They talked about the persons and things that they remembered at school 。Wang Hua is the only person in our school who will attend the ．當(dāng)先行詞前面有who, which等疑問代詞時(shí)。This is the best film that I have ever ．當(dāng)先行詞被the very, the only修飾時(shí)。Any man that / who has a sense of duty won?t do such a the guests that / who were invited to her wedding were important ．當(dāng)先行詞被序數(shù)詞修飾時(shí)。Have you taken down everything that said? There seems to be nothing that is impossible to him in the that can be done has been done.。關(guān)系詞的使用上：A．不可省略 B．不用that C．不可用who 代替whom另外，關(guān)系副詞when和where既可引導(dǎo)限制性定語從句，也可引導(dǎo)非限制性定語從句；但關(guān)系副詞why則只能引導(dǎo)限制性定語從句，不能引導(dǎo)非限制性定語從句。意義上：只是對(duì)先行詞的補(bǔ)充說明，如刪除，主句仍能表達(dá)完整的意思。意義上：是先行詞不可缺少的定語，如刪除，主句則失去意義或意思表達(dá)不完整。如：He loves his parents deeply, both of whom are very kind to the basket there are quite many apples, some of which have gone are forty students in our class in all, most of whom are from big to now, he has written ten stories, three of which are about country 、限制性定語從句和非限制性定語從句根據(jù)從句與主句的關(guān)系是否緊密來區(qū)分，定語從句可分為限制性定語從句和非限制性定語從句兩大類。This is the watch(which / that)I am looking for.(正)This is the watch for which I am looking.(誤)The babies(whom / who / that)the nurse is looking after are very healthy.(正)The babies after whom the nurse is looking are very healthy.（誤）２．若介詞放在關(guān)系代詞前，關(guān)系代詞指人時(shí)只可用whom，不可用who, that；關(guān)系代詞指物時(shí)只可用which，不可用that。The school(which / that)he once studied in is very school in which he once studied is very I?ll bring here the magazine(which / that)you asked I?ll bring here the magazine for which you is the boy(whom / who / that)I played tennis with is the boy with whom I played tennis with ?ll go to hear the famous singer(whom / who / that)we have often talked ?ll go to hear the famous singer about whom we have often manager whose pany I work in pays much attention to improving our working manager in whose pany I work pays much attention to improving our working ：１． 含有介詞的固定短語動(dòng)詞一般不拆開，介詞仍放在短語動(dòng)詞的后面。Please tell me the reason why you missed the don?t know the reason why he looks unhappy didn?t believe the reason(that/which)he explained to me注意：關(guān)系副詞引導(dǎo)的定語從句經(jīng)?？梢杂谩敖樵~+關(guān)系代詞”引導(dǎo)的定語從句來表示。若先行詞是reason, 且定語從句中缺原因狀語時(shí)，用why引導(dǎo)（why=for which）。若先行詞是表地點(diǎn)的名詞，定語從句中缺主語或賓語時(shí)，用that/which引導(dǎo)。She will never forget the day when(=on which)she was married I still remember the day when I first came to this time when we got together finally you remember the years when he lived in the countryside with his grandparent？ Do you remember the days（that/which）we spent together last year?
