[析]a用于以輔音音素開始的單詞前,而an用于以元音音素開始的單詞前,而不是元音字母開頭的單詞前。university的第一個音素是[j],所以用a而不要用an。又如:There is a “n” in the word.是錯句,應(yīng)為:There is an “n”in the word.因字母n的發(fā)音的第一個音素是元音。要注意的還有hour因其第一個字母h不發(fā)音,所以應(yīng)該用an hour。例如:
I need an hour to finish the work.
It is a useful dictionary.
It is a European country.
I bought a used car.
[誤]I need a umbrella because it looks like raining.
[正]I need an umbrella because it looks like raining.
[析]因umbrella的第一個音素是元音,所以應(yīng)用an.常用的情況有:an old man, an English teacher, an elephant, an idea, an hour ago, an honest boy…。
[誤]“Can you help me” “Sorry, I'm in hurry.”
[正]“Can you help me” “Sorry. I'm in a hurry.”
[析]不定冠詞的主要用法如下:?
1. 用來表示一類人或事物,如:She is a teacher.
2. 指某一類人或事物中的一個,如:An elephant is bigger than a horse.
3. 泛指某一人或事物,如:A man is waiting for you at the school gate.
4. 相當(dāng)于“one”的概念,如:I just bought a new dictionary.
5. 其主要的難點是用在固定詞組中:
如:have a walk/a rest /a look
又如:in a hurry 匆匆忙忙
make a face 作鬼臉
do somebody a favour 幫某人忙
a number of =many
又如:have a good time (玩得好)
have a cold (感冒)
have a headache (頭痛)
have a break=have a rest
[誤]I bought the dictionary yesterday. A dictionary is very good.
[正]I bought a dictionary yesterday. The dictionary is very good.
[析]在文章中第一次提到某物時用不定冠詞,而第二次提到時用定冠詞。?

[正]There are nine planets around the sun.
[析]世上獨一無二的天體等名詞前應(yīng)加定冠詞,如:the earth, the moon, the sun, the sky, the sea.

[析]在河流名稱前應(yīng)加定冠詞,如:the Yellow River(黃河)。
[誤]Look, there are Alp.
[誤]Look, there are the Alp.
[正]Look, there are the Alps.
[析]具體的某一座山不加定冠詞,如:Mountain Tai.但在山名稱前加定冠詞后,其山名要加s,來表示山脈。the Alps即為阿爾卑斯山脈。如:The Alps are in the center of Europe.
[誤]Times is one of the oldest newspapers in the world.
[正]The Times is one of the oldest newspapers in the world.
[析]報刊名稱前應(yīng)加定冠詞。?
[誤]Rich are not always happy.
[正]The rich are not always happy.

[誤]Sometimes my parents come to school to see me.

[析]有些名詞被用作其本身原來所含目的時不加冠詞,如:go to school上學(xué),leave school(輟學(xué)),after school(放學(xué)),但如果當(dāng)建筑物講時應(yīng)加冠詞,如例句中其父母來校不是上學(xué),而是看望孩子,則要加定冠詞。又如,He was in hospital for two days.(他在醫(yī)院住院兩天了。)而:He went to the hospital to see his mother.他去醫(yī)院看望他的母親。
[誤]I bought a same dictionary as she bought.
[正]I bought the same dictionary as she bought.
[析]在慣用法the same, the only, the very前的定冠詞不可換為不定冠詞。
[誤]The police caught the thief by his arm.
[正]The police caught the thief by the arm.
[析]這是英文表達(dá)法與中文的明顯不同之處,也是初學(xué)者極易忽視之處。在英語中的某些動詞,如:catch(抓),take(拿),strike (打),pat(拍),hit(擊),hold(握),pull(拉)…動詞后應(yīng)加人,再加介詞on, by, in, with…之后要加定冠詞,再加人體的某一部位。這時的定冠詞千萬不要換作his, her, their, 等詞。
[誤]He was paid by hour.
[正]He was paid by the hour.
[析]by和計量單位之間要有定冠詞。這句話應(yīng)譯為:他的工資是按小時計算的。
[誤]I went to New York by his car.
[正]I went to New York by car.
[正]I went to New York in his car.
[析]by僅僅與交通工具相連表示應(yīng)用某種工具,而加了別的修飾詞后其前面的介詞也應(yīng)作相應(yīng)的轉(zhuǎn)換。如:by car (坐小汽車)by taxi (坐出租車)by bike (騎自行車)by water (乘船)by air (乘飛機)by sea (乘船)

[析]在樂器前要加定冠詞,而在球類游戲之前則不要加冠詞,如:They like to play bridge when they are free. (他們空閑時愛打橋牌)
[誤]The little boy wanted to go to cinema.
[正]The little boy wanted to go to the cinema.
[析]英語中雖有一些名詞與go to連用時不加定冠詞,以表示該名詞的內(nèi)涵,如:go to school (上學(xué)),go to bed(睡覺)等,但去看電影則例外,要用go to the cinema.這也是語言的一個特點。
[誤]I live at 105 the Lake street.
[正]I live at 105 Lake Street.
[析]街道名稱前不用冠詞。?
[誤]Next summer holiday I will go to country to live on a farm.
[正]Next summer holiday I will go to the country to live on a farm.
[析]country既作國家講也作鄉(xiāng)村講。作鄉(xiāng)村講時,一定要加定冠詞,而且只有單數(shù)形式,作國家講時則可有復(fù)數(shù)形式。如:Japan is a country .Japan, China, India are Asian countries.
[誤]The picture looks better at the distance.
[正]The picture looks better at a distance.
[析]at a distance意為“離開一定距離”。而in the distance為“遠(yuǎn)方,遠(yuǎn)處”。這樣常用的詞組有:
as a rule (照例)
in a hurry (匆忙)
in the morning/afternoon (上/下午)
in the sun (在陽光下)
in the rain (雨中)
in the same way (同樣)
in the shade (在陰涼處)
in the day time (白天)
in the end (最終)
on the other hand (換句話說)
on the contrary (相反)
[誤]The little boy and girl walk along the street a hand in a hand.
[正]The little boy and girl walk along the street hand in hand.
[誤]He and you should go to the library to return the books.
[正]You and he should go to the library to return the books.
[析]這主要是英語習(xí)慣上的用法。當(dāng)兩個以上的人稱代詞并列時其排列順序一般為you, he, she, I,而復(fù)數(shù)時為we, you, they:如男女并列時,應(yīng)先男后女,如:He and she …如果在表示不好意思,承擔(dān)責(zé)任時,單數(shù)時用,I, he, she, you, 復(fù)數(shù)時用They, you, we, 如:Tom and I are good friends.
You, he and I must go to play the game for our team this afternoon.
We, you and they have been there before.
I, he and you have to pay for it.
[誤]He or his brother is doing their homework.
[正]He or his brother is doing his homework.
[析]由either…or, neither…nor, or 連接兩個主語時,如果兩主語是單數(shù)時,用單數(shù)代詞,如兩主語是復(fù)數(shù)時,用復(fù)數(shù)代詞,如:Either teachers or students want to do their best to help the old man.如是一單一復(fù)兩名詞時,一般將單數(shù)名詞放在前,復(fù)數(shù)名詞放在后,要用復(fù)數(shù)代詞,如:The teacher or his students will clean their classroom together.
[誤]His brother is taller than him.
[正]His brother is taller than he.
[析]than是連詞,其后應(yīng)視為省略句,than he is.所以要注意區(qū)分其主格與賓格的用法。
I like you as much as she.
[正]I like you as much as her.
[析]as…as 其后也應(yīng)看作是省略句。應(yīng)為as I like her.所以應(yīng)用賓格。而第一句應(yīng)譯為我像她那樣喜歡你。兩句語法都是對的但含義不同。
[誤]Myself did it yesterday.
[正]I myself did it yesterday.
[正]I did it myself yesterday.
[析]反身代詞不可作主語,但可以用作主語的同位語。?
[誤]Take care of ourselves.
[正]Take care of yourselves .(yourself)
[析]祈始句的主語應(yīng)看作第二人稱you.
[誤]Please bring your daughter with yourself.
[正]Please bring your daughter with you.
[析]反身代詞不能作介詞賓語,除非是由不及物動詞與介詞組成的動詞短語,如: The old woman spoke to herself.
[誤]Make yourself home.
[正]Make yourself at home.
[析]這是英語中的習(xí)慣用法,意為“像在家里一樣”。這樣的用法還有:?
enjoy oneself 玩得開心make yourself at home 像在家中一樣
help yourself to something 自己拿某物lost oneself 迷路
seat oneself 就坐dress oneself 穿衣
[誤]— Who's this speaking.— That's Mary.
[正]— Who's that speaking.— This is Mary.
[析]在電話用語中,this指講話人自己,而that指對方。
[誤]The days in summer are longer than this in winter.
[正]The days in summer are longer than those in winter.
[析]在比較句中往往為了避免重復(fù),可以用that或those取代前面提到的事物,如是單數(shù)時用that,復(fù)數(shù)時用those,如:The weather in Beijing is hotter than that in Chang Chun.
[誤]It is so a good book that everyone likes to read.
[正]It is such a good book that everyone likes to read.
[正]It is so good a book that everyone likes to read.
[析]在可數(shù)名詞單數(shù)時可用so+形容詞+不定冠詞+名詞+that從句,也可用such+不定冠詞+形容詞+that從句。在不可數(shù)名詞或可數(shù)名詞復(fù)數(shù)時,只用such, 如:It is such good weather that I want to go swimming. They are such good books that I want to buy them all.在many, much, few, little這4個詞前僅能用so,如: She has so much money that she can buy everything she wants.而在so與that之間僅存形容詞時,則不能用such,如:She is so sweet that everyone likes her.
[誤]I want to buy a same dictionary as yours.
[正]I want to buy the same dictionary as yours.
[析]same與定冠詞the是固定搭配不可更改。這樣的用法還有all the same(仍然)。
[誤]— I hope she might pass the exam.— I don't hope so.
[正]— I hope she might pass the exam.— I hope not.
[析]在作肯定回答時,I think so. I hope so. I believe so.但作否定回答時為:I don't think so. I hope/believe not.
[析]one作代詞時,它的復(fù)數(shù)形式是ones,所有格形式是one's,反身代詞為oneself.如果講One should do one's best.則是對句。如果one與別的詞組成其他詞,如: someone, anyone, everyone或only one 則要用his/her,來作其所有格形式。
[誤]— Who won the game?— None.
[正]— Who won the game?— No one.
[析]由who提問的句子的否定回答中的簡略說法是no one,而由How many提問的句子的否定回答中的簡略語是None.如:How many books are there? None.
[誤]There are many trees on either sides of the street.
[正]There are many trees on either side of the street.
[正]There are many trees on both sides of the street.
[析]either作代詞時由兩個含意,其一是兩者中隨便哪一個,如:You can take either.其二是兩者中的每一個。但要注意的是either后要加單數(shù)名詞,如果作主語則謂語動詞也要用單數(shù)形式。
[誤]I have three sisters. Neither of them is a doctor.
[正]I have three sisters. None of them is a doctor.
[析]neither用于兩者中無一是,而none則用于多于兩者中的人或事物無一是。
[誤]He doesn't like Beijing opera. I don't like too.
[正]He doesn't like Beijing opera, I don't like either.
[析]either作為“也”講時,要用于否定句中,而too則用于肯定句中。
[誤]We like both this little boy.
[正]We both like this little boy.
[析]both作同位語時,它在句中的位置有:在be動詞之后,如:We are both students.在實意動詞之前,如:The parents both want to go to the cinema.用于第一助動詞之后,如:We have both read these English novels.使用時要注意以下句子的實際含意:Both of us are not right.應(yīng)譯為:我們倆不都對。Neither of us is right.才應(yīng)譯為:我倆都不對。又如:I can't give you both of the books.意為:兩本書我不能全給你,而I can't give you either of the books.才為:兩本書我全不能給你。
[誤]We each has a ticket for the concert.
[正]We each have a ticket for the concert.
[析]each作句子主語時其謂語動詞要用單數(shù)形式,如:Each of us wants to learn English well,但each作同位語時,則應(yīng)以原名詞的數(shù)為準(zhǔn)。
[誤]There are ten students here Where are the others students?
[正]There are ten students here.Where are the others?
[正]There are ten students here Where are the other students?
[析]the others=the other students.
[誤]The old man has two sons. One is a teacher, another is a doctor.
[正]The old man has two sons. One is a teacher, the other is a doctor.
[析]another用于泛指,如:Is it far from here to the station?I'm sorry. I have no idea. One may say it is quite near; another may say it is far from here.但在特指時則要用the other.它可以用作定語,the other one,也可以用作代詞the other,但the other用作代詞時它的含意一定是單數(shù)。如果指三者或者三者以上的情況時,則要用one…another…the other.或者one…a second…the third…
[誤]Some people like sports. The others like reading.
[誤]This room is enough large for the students to live in.
[正]This room is large enough for the students to live in.
[析]enough 可以用作代詞,如:There is enough of the food. 又如:Enough has been done for the work,但enough 還可以作形容詞來修飾名詞,這時enough可以放在名詞之前,也可放在名詞之后,如:money enough 與enough money都是對的。但當(dāng)enough作副詞修飾形容詞時,則只能置于形容詞之后了。
[誤]I want any books to read. Do you have any?
[正]I want some books to read. Do you have any?
[析]按照語法any用于疑問句和否定句,而some用于肯定句。
[誤]Would you like any thing to drink?
[正]Would you like something to drink?
[析]在由would you like發(fā)出的問句中,表達(dá)了說話者真心實意要為對方提供些飲料,或在說話者想得到對方的肯定答復(fù)時,在疑問句中要用some而不用any。
[誤]Someone want to meet you.
[正]Someone wants to meet you.
[析]不定代詞應(yīng)被看作單數(shù),即使用and連接兩個不定代詞,也要看作單數(shù),如:?Anyone and everyone has the right. 任何人,每一個人都有這樣的權(quán)力。
[誤]New York is much colder in winter than before.
[正]It is much colder in New York in winter than before.
It is very difficult to learn English well. (作形式主語)
We found it very difficult to answer the question. (作形式賓語)
[誤]Be careful. Don't drink too many.
[正]Be careful. Don't drink too much.
[析]這里much所代的應(yīng)是飲料或水,所以應(yīng)為不可數(shù)名詞。
(二)例題解析
1 These are ___books. Yours are over there.
A I B my C me D mine?
[答案]B.
[析]這里應(yīng)用形容詞性物主代詞。?
2 —___ is she?
— She is a teacher.
A What B How C Who D Where?
[答案]A.
[析]這里的四個疑問詞放在問句中全都成立,但其意義不同。What is she?應(yīng)譯為“她的工作是什么?”或“她是做什么的?”而How is she?應(yīng)譯為“她身體如何?”而Who is she?應(yīng)譯為“她是誰?”其答語應(yīng)為“她叫什么名字。”而Where is she?應(yīng)為“她在什么地方?”由答語決定了這道題的選擇。
