第八節(jié)　定語從句

　　考點(diǎn)一

　　定語從句的基本用法

　　1．限制性和非限制性定語從句

　　限制性定語從句對先行詞起修飾限制作用；非限制性定語從句對先行詞起補(bǔ)充說明作用。非限制性定語從句與先行詞之間往往由逗號隔開。

　　He has two sons who work in the same company.他有兩個(gè)兒子在同一家公司上班。(Perhaps he has more than two sons.)

　　He has two sons，who work in the same company.他有兩個(gè)兒子，他們在同一家公司上班。(He has only two sons.)

　　2．關(guān)系代詞who，whom，whose，that，which，as引導(dǎo)的定語從句

　　(1)who指人，在定語從句中作主語，也可作賓語(限制性定語從句中可省略)。

　　My brother who works in the hospital often looks after the patients carefully.

　　我在醫(yī)院工作的哥哥經(jīng)常細(xì)心照看病人。

　　(2)whom指人，在定語從句中作賓語(限制性定語從句中可省略)。

　　That is the man (whom) I met at the school gate yesterday.

　　他就是我昨天在學(xué)校門口碰見的那個(gè)人。

　　My brother，whom you met the other day，has gone abroad.

　　前幾天你遇見過的我的那個(gè)兄弟出國了。

　　(3)whose指人和物，在定語從句中作定語。

　　She's the student whose handwriting is the best in my class.她就是我的班里書法最好的學(xué)生。

　　I live in a room whose windows face the south.

　　我住在一個(gè)窗戶朝南的屋子里。

　　(4)that指人和物，不引導(dǎo)非限制性定語從句，在定語從句中作主語、賓語(可省略)和表語。

　　These are the pictures (that) I took in China.

　　這些是我在中國拍的照片。

　　[名師點(diǎn)津]　as指人或物，在非限制性定語從句中可指整個(gè)句子，一般作主語、賓語和表語。

　　As is known to us all，China is a developing country.

　　眾所周知，中國是個(gè)發(fā)展中國家。

　　3．關(guān)系副詞when，where，why引導(dǎo)的定語從句

　　(1)when在定語從句中作時(shí)間狀語。

　　I still remember the days when we stayed in England.

　　我仍然記得我們在英國的那些日子。

　　(2)where在定語從句中作地點(diǎn)狀語。

　　This is the place where they used to take a walk after supper.

　　這就是他們過去在晚飯后經(jīng)常散步的地方。

　　(3)why在定語從句中作原因狀語。

　　The reason why he was late is that his mother was ill.

　　他遲到的理由是他母親病了。

　　考點(diǎn)二

　　三組重點(diǎn)關(guān)系詞的區(qū)別

　　1．關(guān)系代詞與關(guān)系副詞的區(qū)別

　　關(guān)系代詞與關(guān)系副詞的區(qū)別主要是在定語從句中的不同作用，關(guān)系代詞在從句中作主、賓、表和定語，而關(guān)系副詞在從句中作狀語。關(guān)系副詞有時(shí)可相當(dāng)于“介詞＋關(guān)系代詞”。

　　Do you still remember the days (that/which)we spent in Qingdao?

　　你還記得我們在青島度過的日子嗎？

　　Do you still remember the days when(＝in which) we spent the summer holidays in Qingdao?

　　你還記得我們在青島過暑假的日子嗎？

　　2．that與which的區(qū)別

　　(1)只用that不用which的情況

　　先行詞是all，much，little，something，everything，anything，nothing，none等不定代詞時(shí)。

　　All that can be done has been done well.

　　能做的都已經(jīng)做好了。

　　先行詞被only，any，few，no，very，little等修飾時(shí)。

　　This is the only thing that I can do now.

　　這是現(xiàn)在我僅能做的事。

　　先行詞是形容詞最高級或序數(shù)詞或被形容詞最高級、序數(shù)詞修飾時(shí)。

　　It is the last train that will go to Shanghai.

　　這是去上海的最后一趟火車。

　　先行詞為人、物并用時(shí)。

　　Do you know the things and persons that they are talking about？你知道他們正在談?wù)摰娜撕褪聠幔?/p>

　　當(dāng)先行詞在主句中作表語，而關(guān)系代詞也在從句中作表語時(shí)。

　　Shanghai is no longer the city that it used to be.

　　上海已不再是過去的那座城市了。

　　(2)只用which不用that的情況

　　引導(dǎo)非限制性定語從句時(shí)。

　　His jokes didn't even raise a smile，which was embarrassing.

　　聽了他講的笑話都沒人笑一下，真是太尷尬了。

　　關(guān)系代詞前有介詞時(shí)。

　　I bought a beautiful skirt，the price of which was very cheap.我買了件漂亮的裙子，其價(jià)格非常便宜。

　　3．which與as引導(dǎo)非限制性定語從句的區(qū)別

　　which as

　　位置上 只能放在先行詞的后面 位置靈活，可位于句前、句中，也可置于句后

　　搭配上 無動詞的限制 謂語動詞通常是表示感覺或心理活動的動詞，如see，hear，know，expect，remember，guess，hope等

　　句意上 意為“這一點(diǎn)” 表示“正如……，正像……的那樣”

　　The air quality in the city，as is shown in the report，has improved over the past two months.

　　正如報(bào)告所顯示的，在過去的兩個(gè)月里，這個(gè)城市的空氣質(zhì)量已有所改善。

　　After graduating from college，I took some time off to go travelling，which turned out to be a wise decision.

　　大學(xué)畢業(yè)后我抽出一部分時(shí)間去旅游，事實(shí)證明這是一個(gè)明智的選擇。

　　考點(diǎn)三

　　“介詞＋關(guān)系代詞”引導(dǎo)的定語從句

　　1．“介詞＋關(guān)系代詞”中介詞后的關(guān)系詞只能是which或whom

　　Do you know the man with whom Mr.Black talked just now?

　　你認(rèn)識剛才和布萊克先生談話的那個(gè)人嗎？

　　2．“介詞＋關(guān)系代詞”中介詞的確定

　　(1)與定語從句中的動詞構(gòu)成搭配，但需注意，有些固定短語中的介詞不能拆開移到關(guān)系代詞前。

　　We can't find the house in which we used to live.

　　我們找不到過去曾經(jīng)住過的房子。

　　This is the person (whom) you are looking for.

　　這就是你找的那個(gè)人。(for不能提前)

　　(2)與定語從句所修飾的先行詞構(gòu)成搭配。

　　The tool with which he is working is called a hammer.

　　他正在使用的那種工具叫作錘子。

　　(3)當(dāng)“復(fù)合介詞短語＋which”引導(dǎo)定語從句時(shí)，這種定語從句常與先行詞用逗號隔開，從句用倒裝語序。

　　He lives in a big house，in front of which stood a big tree.他住在一所大房子里，房前有棵大樹。

　　[名師點(diǎn)津]　“of＋which/whom”表示所屬關(guān)系。

　　Recently I bought an ancient vase，the price of which(＝whose price) was very reasonable.最近我買了個(gè)古代的花瓶，它的價(jià)錢很合理。

　　考點(diǎn)四

　　定語從句的其他要點(diǎn)

　　1．“介詞＋where”引導(dǎo)的定語從句

　　有時(shí)我們可以見到“介詞＋where”引導(dǎo)的定語從句，此時(shí)要與“介詞＋which”引導(dǎo)的定語從句加以比較。

　　He hid himself behind the door，from where he saw the man take a photo of something on the desk.

　　他躲在門后面，從那里他看見那個(gè)人拍攝了桌子上的什么東西。(from where 指from behind the door而不是from the door)

　　2．當(dāng)先行詞是case，condition，situation，position，point，stage等表示抽象意義的名詞時(shí)用關(guān)系副詞where引導(dǎo)定語從句。

　　They have reached the point where they have to finish the task in 5 days.

　　他們已經(jīng)到了不得不5天內(nèi)完成這項(xiàng)任務(wù)的地步了。

　　3．在定語從句中，the way在從句中充當(dāng)方式狀語時(shí)，其后的關(guān)系詞可以是in which，that或省略；但是當(dāng)它在從句中充當(dāng)主語、賓語等成分時(shí)，其后的關(guān)系詞就用that或which。

　　What surprised me was not what he said but the

　　wayhe said it.

　　讓我吃驚的不是他說的話，而是他說話的方式。

　　The way he explained to us was quite simple.

　　他向我們解釋的那種方法很簡單。

　　4．先行詞是time，若time作“次數(shù)”講時(shí)，應(yīng)用關(guān)系代詞that引導(dǎo)定語從句，that可省略；若time作“一段時(shí)間，時(shí)代”講且作狀語時(shí)，應(yīng)用關(guān)系副詞when或介詞at/during＋which引導(dǎo)定語從句。

　　This is the second time (that) the President has visited the country.

　　這是總統(tǒng)第二次訪問這個(gè)國家了。

　　This was a time when/during which there were no radios，no telephones or no TV sets.

　　這是一個(gè)沒有收音機(jī)、沒有電話，也沒有電視的時(shí)期。

　　5．whose和of which/whom引導(dǎo)的定語從句

　　whose和of which/whom可以相互代替，但順序不同，whose＋名詞＝the＋名詞＋of which/whom。

　　This is the scientist whose name(the name of whom)is known all over the world.

　　這就是那位世界聞名的科學(xué)家。

　　6．分隔式定語從句

　　定語從句有時(shí)不直接跟在先行詞之后，而是中間由一個(gè)定語、狀語或謂語隔開。

　　There is an expression in her eyes that I can't read.

　　我不能理解她眼神中表達(dá)的東西。

　　[名師點(diǎn)津]　定語從句中的謂語動詞與先行詞保持一致。

　　試比較：

　　He is one of the students who have passed the driving test.他是通過駕照考試的學(xué)生之一。

　　He is the only one of the students who has passed the driving test.

　　他是唯一一位通過駕照考試的學(xué)生。

　　[本節(jié)小結(jié)]

　　從歷年的高考試題來看，主要考查引導(dǎo)定語從句的關(guān)系代詞或關(guān)系副詞的選擇、關(guān)系代詞which和that的區(qū)別、“介詞＋關(guān)系代詞”引導(dǎo)的定語從句的用法、引導(dǎo)非限制性定語從句的關(guān)系代詞as和which的區(qū)別等方面。定語從句一般緊跟在先行詞的后面，但有時(shí)為了行文的需要，先行詞與定語從句直接也會被同位語、狀語、謂語等成分分開，解決這類題目的關(guān)鍵是把分隔部分去掉，并能夠正確查找先行詞。
