the用法歸納
歸納指歸攏并使有條理,也指一種推理方法,由一系列具體的事實概括出一般原理。下面是小編整理的the用法歸納,希望能夠幫助到大家。
the用法歸納1
一、根據主語辨析
雖然三者均可表示“花費”,但所用主語不同:take的主語可以是事或物(包括形式主語it),也可以是人;spend的主語只能是人,不能是事或物;cost的主語通常是事或物(包括形式主語it),不能是人。如:
It took me an hour to write the letter.我寫這封信花了一個小時。
I spent an hour writing the letter.(譯文同上)
The letter took me an hour (to write)(譯文同上)
The computer cost (me) $2000.這臺電腦花了(我) 2000美元。
It costs $1000 a year to run a car.使用一輛車每年要花1000美元。
I have spent all day looking for you.我花了一整天找你。
注:若cost不是表示“花費”,而是表示客觀地或被動地“耗費”,則也可用人作主語。如:Smokers cost them a lot of money every year.抽煙的`人每年要耗費他們不少錢。
二、根據賓語辨析
take的賓語通常是時間,cost的賓語通常是錢,而spend的賓語則可以是時間或錢。如:
It took her two hours to walk to the station.走路去車站花了她兩小時。
He spends much time (money) on books.他花了很多時間讀(錢買)書。
How much did it cost to build the bridge?建這座橋花了多少錢?
注:cost有時也用于時間,但通常只用于籠統時間(一般不用于具體明確的時間)。如:Making experiments like this costs much time and labour.做這樣的實驗要花很多時間和勞力。
按傳統語法,take的賓語通常是時間,但在現代英語中,用錢作其賓語的現象已很普遍。如:It takes a lot of money to buy a house.買一座房子要花一大筆錢。
三、根據句型辨析
從句型結構來看。三者的通常句型為:
it costs (sb) money to do sth做某事花某人多少錢。
sb spends time (money) on sth某人在某一方面花多少錢。
sth costs (sb) money某物花某人多少錢。
sb spends time (money) in [on] doing sth某人在做某事方面花多少錢。
it takes sb time (money) to do sth = it takes time (money) for sb to do sth做某事花某人多少時間或錢。
sth takes sb time (money) to do某事花某人多少時間或錢去做。
sb takes time (money) to do某人花多少時間或錢去做某事。
the用法歸納2
一、定義:
定語由一個句子來充當,那么這個句子就叫做定語從句。
eg: 其中劃線部分為定語從句。
二、分類:
分為限制性定語從句和非限制性定語從句,還有間隔性定語從句。 (限制性定語從句)(非限制性定語從句)(間隔性定語從句)
注:定語從句和非限制性定語從句的區別。
限制性定語從句無逗號隔開、不可缺少、起修飾限制作用;而非限制性定語從句有逗號隔開、可有可無、起補充說明作用。
三、構成:
定語從句有先行詞、引導詞和從句構成。
先行詞是定語從句所修飾限制的名詞或代詞。
引導詞是用來引導定語從句的關系代詞或關系副詞。
eg: The old town has narrow streets and small houses that are built close to each other.此句中先行詞為:narrow streets and small houses, 引導詞為:that, 定語從句為:that are built close to each other
四、基本原則
定語從句中不能出現與先行詞在意義上相一致的詞 與book指同一物,所以要去掉。)
五、定語從句中常見考點:
考點一.關系代詞和關系副詞的辨別
1.關系代詞that(人、物),which(物)、who(m)(人)、whose(某人的,某物的)、as。
2.關系副詞when(表時間)、where(表地點)、why(表原因)。
注:關系副詞可變為“介詞+關系代詞”結構(即:關系副詞=介詞+關系代詞)。eg:This is the mountain village where(=in which)I stayed last month.
3.怎樣選擇正確的關系代詞或關系副詞 方法一:找出先行詞和定語從句中動詞,看定從中動詞與先行詞能否構成習慣搭配。能,用關系代詞;不能,用關系副詞.
Eg.I will never forget the day定從中動詞spent 與先行詞
the day 構成spent the day ,所以用關系代詞that或which或省略)
系代詞。如不缺少,定語從句所表達意思相對完整,用關系副詞。
eg:
①This is the factory ____ made cars .(缺少主語,所以用關系代詞that 或which,作主語不能省略)
②This is the reason _______ he was late for school.(定語從句he was late for school 表
達意思相對完整,所以用關系副詞why 或介詞+關系代詞for which) 注意:當先行詞為case、position、point、situation、society、activity等抽象意義的名詞時,常用關系副詞where引導定語從句.
eg:He got himself into a dangerous situation where he may lose control of the plane .
考點二.定從中that 與which的區別
1.關系代詞只用that的情況。
(1)當先行詞為不定代詞(all、much、little、few、some、any、none、one、something、anything、everything等)或先行詞被不定形容詞(all、many、some、few、little等)修飾時。 that you want to say for yourself?
(2)當先行詞既有人又有物時。 that you are talking about.
(3)當先行詞含有序數詞或最高級時。
eg: ① will go to Beijing.
②(4)當先行詞被only、very、next、last等修飾時。
that I’m looking for.
(5)在who或which引導的特殊疑問句中。 that you lost?
(6)當關系代詞在定語從句中作表語時。 that it used to be.
2.關系代詞只用which的情況。
(1)引導非限制性定語從句時。
eg:He turned to be a very successful man,(2)在“介詞+關系代詞”結構中,關系代詞只用which。
eg:This is the question they have so much discussion in the past few weeks.
(3)當關系代詞后有插入成分時。
eg: Mary was much kinder to Jack than she was to the others, which, of course, made all the others upset.
3.指人時,關系代詞只用who(m)的情況。
(1)引導非限制性定語從句時。 (2)當“介詞+關系代詞(賓格形式)”結構引導定語從句時。 (3)當關系代詞后有插入成分時。
eg:This is my friend who,I think,is the best in our class..
(4)在There be句型結構中,先行詞指人時。
eg:There is a young lady who asks for you.
考點三:as的用法及as與which的區別
1.as引導的定語從句
(1)as常用于固定搭配中:the same...as,such…as,as/so…as
eg:①比較:Zhengzhou is such a wonderful city that everyone likes to visit it.
注意:第一句是定語從句,所以定從中沒有出現與先行詞city 意義上一致的詞,第二句是狀語從句,that 后應為完整句子,所以it 不能省略。
②同樣的但不是同一輛)
比較:Today he wears the same coat that he did yesterday .(同一件衣服)
(2)as常用于固定句型中:as we all / everyboby know(s), ,as is often the case,as we expect等。
eg:As we all know,Zhengzhou is an attractive city.
2.在非限制性定語從句中,as與which的區別
⑴指代整句話內容時,as可位于主句前面、中間或后面;而which一般位于主句后。另外,which還可指代一個名詞或一個短語。
eg①: As we all know,Tom is a good boy.
②:China,which was founded in 1949,is becoming more and more powerful.
③:She doesn't think she is wrong,which makes her teacher angry.(which指代上文整個句子)
⑵.aswhich沒有,
eg: ①He succeeded this time,as had been expected.
②She has made great progress,which makes her parents very happy.
③As we all know,knowledge changes life.
考點四.定從中所屬關系的表達
whose引導定語從句時必須和名詞放在一起。whose+n(s)=the+n(s)+of which/whom=of +which/whom+the+n(s)
考點五.定從中動詞形式與先行詞的一致
eg: ①②③
考點六.the way作先行詞引導定從時,關系詞可用in which/that/省略。
eg:I don’t like the way that/in which/省略he spoke to me.
考點七.介詞+關系代詞
在這種結構中,關系代詞表示人,只能用whom ;關系代詞表示物,只能用which。
怎樣選擇正確的介詞
1.根據定語從句中謂語動詞的習慣搭配來決定。如:
① This is the pen on which I spent 10 yuan.(spend money on sth.為固定搭配)
② This is the pen for which I paid 10 yuan.(pay money for sth.為固定搭配)
2.根據先行詞的搭配習慣來決定。如:
① I remember the day on which I graduated from high school.(強調在具體某一天要用介詞on)
② I remember the days during which I lived in Russia.(強調在某幾天時間內要用介詞during)
③ I remember the month in which I got along with Tom(在month前介詞要用in)
3.根據從句中動詞與先行詞的邏輯關系。
Is that the newspaper for which you often write articles?(write ...for the article)
4.根據從句中形容詞的習慣搭配。
①The secretary with whom the boss is not happy will be fired for her carelessness .( be happy with "對表示滿意") 老板對其不滿意的'那個秘書將由于她粗心而被解雇。
②He is a learned man with whom we are familiar.( be familiar with 對...熟悉)他是一位我們熟悉的有學識的人。
5.有些“動詞+介詞”的固定詞組不可拆開用
常見的動詞詞組有:look for,look after, care for,send for,hear of,hear from, deal with,
get through,pay attention to等。 Eg .This is the watch (which/that) I am looking for.這是我正在找的手表。 This is the watch for which I am looking.(錯誤)
6.“不定代詞both,some,any,many,(a)few,none,neither等 +of whom 或of which,表示整體與部分的關系或所屬關系
eg: ①(很多蘋果中有一些是紅色)
比較:I have many apples and some of them are bad .
②比較:He has three children but none of them is kind to him .
7.“介詞+which+to do”作定語的情況
介詞+which+to do作定語相當于介詞+which引導定語從句。其中定語從句主語與主句主語一致,且從句含有情態動詞。
eg:①Frank’s dream was to have a shop in which to produce the workings of his own hands.
(=Frank’s dream was to have a shop in which he could produce the workings of his ownhands.)
②He has no house in which to live.(=He has no house in which he can live.)
8.“介詞+where”引導的定語從句的情況
有時候,我們可以見到“介詞+where”引導定語從句的情況。此時,where代替的是表示地點的介詞短語。
eg:You can look out of the window,from where you get a good view.(其中where=out of thewindow)
考點八:定從句與短語的轉化
1.The girl (who is )dancing now just returned from Beijing.正在跳舞的女孩剛從北京回來。
2.I love the stories (which were) written by Mary .我喜歡瑪麗寫的故事。
