1、Lecture 4: Determiners,限定词(DETERMINER是在名词词组中对名词中心词起特指(SPECIFIC REFERENCE、类指(GENERIC REFERENCE以及表示确定数量(DEFINITE QUANTITY和非确定数量(INDEFINITE QUANTITY等限定作用的词类。名词词组除有词汇意义外,还有其所指意义(REFERENTIAL MEANING,是特指(即指特写的对象,还是类指(即泛指一类人或物;是有确定的数量,还是没有确定的数量。能在名词词组中表示这种所指意义的词类就是限定词。,英语的限定词包括: 定冠词(DEFINTITE ARTICLE,不定冠词(

5、r等物主限定词和名词属格(Johns, my friends等能与三类名词搭配。 例如: the book, my book, my friends book, Johns book, any book, some book, no book, the other book, whose book the books, my books, my friends book, Johns books, any books, some books, no books, the other books, whose books the money, my money, my friends money
6、, Johns money, any money, some money, no money, the other money, whose money.,2只能与单数名词搭配的限定词 有些限定词如a(n), one, another, each, every, either, neither, many a, such a 等只能与单数名词搭配。 例如: each worker, either book, an apple, another book, such a book, every student, neither sentence, one copy, many a book. 3
7、) 只能与复数名词搭配的限定词 有些限定词如both, two, three, another two / three, many, (a) few, several, these, those, a (great) number of等只能与复数名词搭配。 例如: both workers, several students, a number of essays, many students, (a) few words, these / those books, two / three visitors, another two / three students. 4) 只能与不可数名词
8、搭配的限定词 有些限定词如a (little) bit of, a great amount of, a great deal of, (a) little, much等只能与不可数名词搭配。 例如: a bit of water, a great amount of labour, a great deal of work, (a) little space, much noise .,5)能与单、复数名词搭配的限定词 有些限定词如the first, the second, the last, the next等既可与单数名词搭配,也可与复数名词搭配。 例如: the first rose
9、, the last man, the next meeting, the first roses, the last men, the next meetings. 6能与单数名词和不可数名词搭配的限定词 有些限定词如this, that, (the) least等能与单数名词和不可数名词搭配。 例如: (the) least sign (of prejudice), this / that job, (the) least knowledge, this / that work. 7能与复数名词和不可数名词搭配的限定词 还有些限定词如a lot of, lots of, enough, m
10、ore, most, such, other等可与复数名词和不可数名词搭配。 例如: a lot of books, a lot of money, lots of chickens, lots of food, plenty of chairs, plenty of water, enough copies, enough coal, more articles, more time, most people, most work, such men, such bread, other men, other bread. 不定量限定词less原先只与不可数名词搭配,但在现代英语中,less
11、既可与不可数名词也可与复数名词搭配。 例如: less money, less mistakes.,2 限定词与限定词的搭配关系 以上讲的是限定词与三类名词的搭配关系。除上述搭配关系外,限定词与限定词之间还存在着一定的搭配关系。在名词词组中心词之前如果有两个或两个以上限定词出现时,就会产生限定词的先后顺序问题。按其不同的搭配位置,限定词可分为:,1中位、前位、后位限定词 按照限定词与限定词之间不同搭配位置,限定词可分为中位限定词(CENTRAL DETERMINER、前位限定词(PREDETERMINER和后位限定词(POSTDETERMINER。 a) 中位限定词包括a(n), the, z
12、ero; this, that, these, those; my, your, etc; Merrys, my friends; some, any, no, every, each, either, neither, enough; what(ever), which(ever), whose等 b) 前位限定词包括all, both, half; double, twice, three times, etc; one-third, two-fifths, etc; what, such, (a / an)等 c) 后位限定词包括one, two, three, etc; first,
13、second, third, etc; next, last, other, another, etc; many, much, (a) few, (a) little, fewer, (the) fewest, less, (the) least, more, most; several, plenty of, a lot of, lots of, a great / large / good number of, a great / good deal of, a large / small amount of; such等,2) 三类限定词的搭配关系 如果一个名词词组带有上述三类限定词,
14、其搭配关系总是按照“前位中位后位”的顺序排列。 例如: all前the中four后teachers. all前your中three后books. all前these中last后few后days. 如果只有上述两类限定词,其搭配关系仍按上述顺序。 例如: half前his中lecture. those中last后few后months. several后hundred后guests. all前other后students. such前a中misfortune. some中such后alloy.,由上述诸例可以看出,中位限定词之间和前位限定词之间是互相排斥的,即一个名词中心词之前不可并用两个中位限定
15、词或两个前位限定词。 所以,“我的那本书”不是* my that book而是that book of mine,因为my和that同是中位限定词,不可同时并列。 但后位限定词的使用却不受此限。除上述those last few months, several hundred guests之外, these last two books, the first two chapters, three other girls, two more sheets, the next few weeks, many more copies, a few more samples, another twe
16、nty tons等都是后位限定词重叠使用的实例。 个别限定词有跨类现象,如such既属于前位限定词,又可归入后位限定词。由于它只是在such a.和such an.这样的搭配中属于前位限定词,而在与其他限定词(some, any, no, all, few, another, other, many, one, two, etc)搭配时,such则是后位限定词,一律放在上述这些限定词的后面,如some such, any such, no such, few such, one such等,因此通常把它归入后位限定词。,3 若干限定词用法比较 前两节介绍了限定词与三类名词以及限定词与限定词之间
17、的搭配关系。下面介绍一些限定词(包括相应的不定代词的某些习惯用法问题。,1many, much, a lot of, lots of, plenty of 表示“多”的意思,可用many, much, a lot of, lots of, plenty of等。但是many, much常用于否定句和疑问句,而a lot of等则常用于肯定句。 例如: I havent seen many English films. 多数英文电影我没看过。 many修饰可数名词 Have you seen many English films? 多数的英文电影你都看过吗? many修饰可数名词 I haven
18、t done much work today. 我还没有做多少活呢。 much修饰不可数名词 Have you done much work today? 今天你已经做了很多活吗? much修饰不可数名词 I have seen a lot of / lots of / plenty of / a great number of English films. 我已经看了多部英文电影。 number修饰可数名词 I have done a lot of / lots of / plenty of / a great amount of work today. 今天我已经做了很多活。amount修
19、饰不可数名词,many / much 既可作限定词,也可作不定代词(INDEFINITE PRONOUN,a lot 也可单独用作名词词组: Have you done all these exercises? -No, I havent done very many. Have you done much work today? -Yes, Ive done a lot. 当然,以上所讲many / much常用于否定句和疑问句并不是绝对的,尤其是在下列场合many / much也常用于肯定句:,a) 用于whether / if引导的宾语分句中。 例如: I doubt whether /
20、 if therell be many people at the show on this rainy day. 我怀疑在这个雨天里会有很多人看表演。 I wonder whether / if he has much information on this subject. 我想知道在这个题目上他是否知道很多消息。,b) 用于由“how / too / so / as many / much ( 中心词)” 构成的名词词组中。 例如: He took so many boxes with him that he had to call a taxi. 他身边带着太多的箱子,不得不叫计程车。
21、 Its really surprising that the child has so much strength at his age. 真是很惊奇,在这个年龄的孩子居然这么有力气。 You can take as many copies as you need. 你可以根据你的需要想拿多少张就拿多少张。 You can use as much oil as you need. 根据你的需要想用多少油就用多少。 I have (far) too many books on the shelf. Weve had too much rain this spring. 这个春天我们已经有太多雨
22、。 Id like to know how many copies are needed for the class. 我想要知道在这班需要多少张考贝。 I want to know how much money will be spent on the project. 我想知道将在这个计划花费多少钱。MUCH修饰不可数名词MONEY。,c) 用于在句首作主语以及在“存在句”中作实义主语的名词词组中。 例如: Many people would like to take holidays abroad. 许多人喜欢去国外渡假。 Much coal has been saved through
23、 the use of the new device. 通过用新的装置,很多煤被节省下来。 There are many girl students in my class. 在我的班级里有许多女学生。 There is much coal left in the mine. 在煤矿有很多的煤剩下。 同样地,a good / great many也可用于肯定句。 例如: I have read a great many English novels. 我已读过大量的英语小说。,2) (a) few, (a)little 表示“少”的意思,可用(a) few, (a) little, 既可用作限
24、定词,也可用作不定代词。a few, a little表示“少量”,带有肯定意义。 例如: Lets invite a few friends to come with us. 让我们来邀请几个朋友来和我们在一起。 Here are a few more books on this subject. 在他的课题上有少量的书。 There are only a very few left. 只有一点点剩下。 Im keeping the few that remain for tomorrow. 我保住剩下的一点点为明天。 I had a little difficulty in solving
25、 the problem. 在解决这个问题上我有一点困难。 Give me a little of that wine. 给我一点那种酒。 Im trying to use the little French I have just learnt. 我正在试用我刚学的一点法语。,few / little 若不与a 连用则表示否定意义,相当于not many / much, not enough。 例如: I have very few (chocolates) left. 我剩下不多的巧克力。 Few (children) were tired. 很少的学生累了。 I have very li
26、ttle (money) left. 我有为数不多的钱剩下。 I understood little of his speech. 他的演讲我懂一点点。 要注意,quite a few, a good few. not a few不表示少,而表示相当多的含义,相当于, a fair number (of)。 例如: Quite a few of us are getting worried. 我们相当多的人正在担心。 Youll have to wait a good few weeks. 你将不得不等上相当多个星期。 little 的比较级和最高级是less 和least, 通常只能用与不可
27、数名词搭配,但在当代英语中也有用less与复数搭配的。 例如: If only there were less holes in the roof. 如果房顶仅是少量洞。但这只见于非正式主体;在正式主体中仍用fewer为好。,3) some, any 要表示“一些”的意思,可用some, any。 some 是肯定词(ASSERTIVE WORD,常用于肯定句;any是非肯定词(NONASSERTIVE WORD,常用于否定句或疑问句。 例如: There are some letters for me. There arent any letters for me. Are there an
28、y letters for me? I seldom get any sleep these days.,any也常用于条件分句以及带有否定含义的句子中: If you have any trouble, please let me know. 如果你有任何麻烦,请让我知道。 I forgot to ask for any change. 我忘了要一些零钱。 当说话人期待肯定回答时,some也可用于疑问句, 比如当说话人期待来信时,他可以问道: Are there some letters for me? 当购物时向售货员提问或者主人向客人表示款待时,也可在疑问句中用some: Could I
29、 have some of these apples? Would you like some chocolate cake? 当some与单数可数名词搭配时, some相当于a certain(“某一”的含义;而any与单数可数名词搭配,则相当于 every(“任何一个”的含义。 例如: Some boy has broken a window. 有个男孩打破了窗户。 Any child could answer that question. 任何一个孩子都可以回答这个问题。,4) all, both, every, each, either, neither, any 这一类词,除ever
30、y只能作限定词外,都是既可作限定词,也可作不定代词。 例如: all (of) the boys. both (of) the boys, every boy / every one of the boys, each boy / each (one) of the boys, either boy / either (one) of the (two) boys, neither boy / neither (one) of the (two) boys, any boy / any (one) of the (three or more) boys, 由上述诸例可以看出,这一类的限定词和不
31、定代词在用法上有以下值得注意之处:,a) 表示“全体”,可用all 和both, 但all表示三个或三个以上人或物的“全体”,而both则表示两个人或物的“全体”。 例如: All the four applicants are below the average. 所有这四位申请者都在平均数以下。 All these last few days the farmers have been busy fighting drought. 在最后这几天里,农民曾经忙于抗旱。 Both his parents are against his going there alone. 他的父母两个人都反对
32、他单独去那儿。 The man was blind in both eyes. 这人的两眼都瞎了。,如果要表示全体都不的意思,当全体为三个或更多的人或物时,通常用none。 例如: None of the students failed the examination. 没有一个学生考试失败。 Ill have none of your stupid ideas. 我不能接受你的那些糊涂观念。 在上述第一例中,既可用none, 也可用no one: No one failed the examination. 但no one只能指人,不能指物。 如果要表示两个人或物都不,通常要用neither
33、: Neither of the students passed the exam. Neither (one) of the (two) cars was made in Japan. 两辆车没有一辆产自日本。,b) 表示全体中的每个,如果这个全体包含三个或更多的人或物,通常用every。 例如: Every student in the class took part in the performance. 这个班的每个学生都是这个表演的一部分。 His every action shows that he is a very determined young man. 他的每个行动都显示
34、了他是一个坚决的年轻人。 如果这个全体包含两个或两个以上的人或物,便可以用each。 例如: Each side of the street was crowded with people. 街道的两边都挤满了人。 在这里,不可以用every。 如果说广场的每一边都挤满了人,那就既可用each, 也可用every: Each / Every side of the square was crowded with people. 广场的边上挤满了人。,every 与each 的区别还在于every 指许多人或物中的“每个”,侧重在全体,近乎all的含义。 例如: Every student fa
35、iled the examination. = All the students failed the examination. 所有的学生都考试失败。 We want every child to succeed. = We want all the children to succeed. 我们相让每个孩子都成功。 而each则指许多人或物中“各人”,侧重在个别。 例如: Each child will find his own personal road to success. 每个孩子都发现自已的方法成功。 The Queen shook hands with each player
36、in turn after the game. 女王在比赛后与参赛手们轮流握手。,c) 表示全体中的任何一个,也要看这个全体是包含三个或更多,还是只包含两个。当全体包含三个或三个以上,要表示其中任何一个须用any。 例如: Any (= Every) child would know that. 每个孩子都知道这个。 Ask any man you meet. 你可以问任何一个人。 His gift was unknown to any (of them) except himself. 除了他自已没有一个人知道他的礼物是什么。 These are all free,take any (of
37、them) you like. 所有都是免费的,拿其中你最喜欢的。 当全体只包含两个时,要表示其中任何一个须用either。 例如: There are two flights for Beijing in the morning. You can take either (one). 只有两班早晨的飞机去北京,你可选其中一个。 We have two copies left. Keep either (copy) for the file. 我们有两份考贝剩下,为文件保持其中的一份。 但在on either side, on either end等固定词组中有时可以兼指两个。 例如: The
38、re are warehouses on either side of the river (= on both sides of the river). 在河的两边都有大货仓。 He got off the train with a bundle on either arm. 他带着两大包下火车。 There are stairways at either end of the corridor. 走廊的两头都有楼梯。,冠词,冠词(ARTICLE)是最典型的限定词。 1 类指和特指 冠词的表意功能可以归纳为二种,即类指(GENERIC REFERENCE)和特指(SPECIFIC REFER
39、ENCE)。冠词是虚词,本身不能单独使用,也没有词义,它用在名词的前面,帮助指明名词的含义。英语中的冠词有三种,一种是定冠词(the Definite Article)(定冠词the与指示代词this,that同源,有“那(这)个”的意思,但较弱,可以和一个名词连用,来表示某个或某些特定的人或东西。); 另一种是不定冠词(the Indefinite Article)(不定冠词a (an)与数词one 同源,是“一个”的意思。a用于辅音音素前,一般读作e,而an则用于元音音素前,一般读做en。); 零冠词(zero Article)。,1类指 类指是表示类别,也就是泛指一类人或物。不论是定冠词
40、还是不定冠词和零冠词都具有这种功能。 比如定冠词与单数可数名词搭配,往往可起类指的作用,常用于正式语体。 例如: Galileo claimed that he had invented the telescope. GALILEO声称他发明了望远镜。 The horse has been replaced by the railroad, the windship by the steamship. 铁路代替了马的作用,汽船代替了帆船。 定冠词与某些形容词或分词连用,表示类别或抽象概念,也是一种类指用法。 例如: the rich 富人; the living 生者。表示一类人。 The s
41、ick have been cured, the lost have been found, and the dead have been revived. 病被治逾,失去的被找回来了,死亡被挽救回来了。 The rich get richer, and the poor get children. 有钱的更有钱,穷人得了孩子。 The true, the good and the beautiful would not exist without the false, the evil and the ugly. 没有欺骗、邪恶、丑陋就没有真实、善良和美丽。,用不定冠词与单数可数名词搭配也可
42、表示类别。 例如: An ox is a useful animal. 公牛是一个有用的动物。 My brother William is planning to be a lawyer. 我的兄弟WILLIAM打算成为一名律师。 用零冠词与复数可数名词或不可数名词搭配,同样可以表示一类的人或物。 例如: Doctors are badly needed at the front. 在前线医生是非常地需要。 Carrots are my favorite vegetable. 胡罗卜是我最喜爱的蔬菜。 They are teachers, not students. Cats and tige
43、rs belong to the same family of mammals. 猫和老虎是在一个家族的动物。 Electricity is a form of energy. 电是能量的一种形态。 Unity is strength. 团结就是力量。,2特指 特指不同于类指,它不是泛指一类人或物,而是特指一类人或物中的具体对象。这里有两种情况: 一种是非常明确地指出何人或何物,这叫做“确定特指”(DEFINETE SPECIFIC REFERENCE。定冠词常作这种用法。 例如: He bought a house.Ive been to the house. 他买了幢房子。我去过那幢房子。
44、 指上文提到过的人或事。 We own a dog and a cat. The dog is brown, and the cat is white. 我们有一只猫和狗。狗是棕色的,猫是白色的。 特指上文提到过的狗和猫。 The dog and the cat are the same ones we had last year. 这狗和猫是我们去年就养了的。 特指去年就饲养了的狗和猫。,另一种情况是“非确定特指”(INDEFINITE SPECIFIC REFERENCE,这也是特指具体对象,但不很明确。不定冠词常作这种用法。 例如: I met an old man in the str
45、eet. 我在路上遇到一个老人。 虽未道出姓名但所指仍为某一特定的老人。 I have lost a button. 我丢了一只钮扣。 指失落一颗特定的钮扣,但未说出何种钮扣。 Theres a letter for you. 有一封信给你。 指一封特定的信件,但不明确是谁写来的。 零冠词也能有非确定特指的用法。 例如: The streets are clean and shaded with trees. 马路干净且有树的阴凉。 She put carrots in the stew. 她把胡罗卜放入炖汤里。,3后照应特指、前照应特指、语境特指 确定特指又可分为后照应特指(ANAPHORI
46、C SPECIFIC REFERENCE、前照应特指(CATAPHORIC SPECIFIC REFERENCE和语境特指(SITUATIONAL REFERENCE。 后照应特指即用定冠词表示上下文已经提到的人或物。第一次提及用不定冠词。第二次提及用定冠词。 例如: He ordered a book some time ago. The book has now arrived. 他以前某个时候定购的书,现已经到达。 前照应特指也是一种确定特指,只是照应对象不在上文,而在下文,或者更确切地说,定冠词的指定作用决定于名词中心词的后置修饰语。 例如: Please tell us the st
47、ory of Franklin. 请告诉我FRANKLIN的故事。 Is this the train for Shanghai? 去上海是这次火车吗? Here is the student I told you about. 这就是我告诉你的那个学生。,语境特指不是建立在上下文基础上的照应关系,而是建立在谈话双方共有的知识上。 比如主妇对丈夫说,Im just back from the market, 在这种语境中,听话人一定会理解the market指某个平时常去的市场。 又例如: Take the medicine.把药吃了。 特指双方都明白的人或物。 Whats in the pa
48、per(s) today? Shut the door, please. Hows the cough today? He turned on the radio. Whats on the radio? 能用于语境特指的冠词通常是定冠词,但是零冠词在一定上下文中也可表示确定特指含义,这也是一种语境特指。 例如: Mary asked, Why is father out of work? John was elected chairman of the studentsunion. JOHN被选作学生会主席。,2 冠词的习惯用法 我国学生对冠词用法之所以感到困难,不仅是由于汉语没有冠词,而且
49、冠词用法尽管有规律可循,例外却太多。有时,冠词的使用仅仅是个习惯用法问题,很难用几项语法条文加以概括。 例如radio和television两词用于类指时通常不带定冠词: Its easier to write plays for television than for radio. 写电视剧本要比写无线电广播剧本容易的多。 但要说listen to the radio, on the radio;而在television之前却又可以不用定冠词watch (the) television, on (the) television。 又例如,疾病通常是不可数名词,前面不用冠词: Shes had
50、 appendicitis. I think Ive got measles. 但有例外,比如说感冒要用冠词,Ive got a cold, 可是在catch (a) cold中,人们有时又不用冠词;在头痛前要用冠词,Ive got a headache,但在牙痛、耳痛前却又不用冠词,Ive got had toothache。 下面列举一些冠词的习惯搭配关系。,1习惯用定冠词 at the hands of; on the shoulder; by the way; on the spot当场; for the time being暂时; on the whole; in the case
