英语中的限定词
限定词的种类

限定词的种类限定词是英语中一类用来修饰名词或名词性短语的词汇,起到限制或具体化名词的作用。
在英语语法中,常见的限定词包括冠词、指示代词、形容词性物主代词、数量词、基数词、序数词、不定代词等。
本文将分别介绍并解释这些限定词的种类和用法。
一、冠词 (Articles)冠词是指用来限定名词范围的词语,分为定冠词和不定冠词两种。
1. 定冠词 (Definite Articles)定冠词包括"the",用于特指已提及或共知的人、事物或概念。
例如:- The book on the table is mine.(桌子上的那本书是我的。
)- The sun rises in the east.(太阳从东方升起。
)2. 不定冠词 (Indefinite Articles)不定冠词包括"a"和"an",用于泛指或表示名词是一个类别中的任意一个。
例如:- I saw a bird in the garden.(我在花园里看到一只鸟。
)- She wants to be an actress.(她想成为一名女演员。
)二、指示代词 (Demonstrative Pronouns)指示代词指代特定的人、事物或位置,并且根据离说话人的距离分为远指和近指两种。
1. 远指代词远指代词包括"that"和"those",用于指代离说话人较远的事物或人们。
例如:- That is a beautiful sunset.(那是一个美丽的日落。
)- Look at those flowers over there.(看看那边的花。
)2. 近指代词近指代词包括"this"和"these",用于指代离说话人较近的事物或人们。
例如:- This is my new car.(这是我的新车。
)- These are my friends.(这些是我的朋友。

several hundred guests 后 后 such a misfortune 前 中
all other students 前 后 some such alloy 中 后
有上述诸例可以看出,中位限定词和前位限定词之间是相互排 斥的,即一个名词中心词之前不可并用两个中位限定词或两个前位 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,不可并列。但后位限 定词的使用却不受此限制。例如: his 中 two 后 last two books 后 后 more sheets 后 the first two chapters 中 后 后
基数词(Cardinal Numeral)和序数词(Ordinal Number)
倍 数 词 ( Multiplicative Numeral ) 和 分 数 词 ( Fractional Numeral) 量词(Quantifier):a lot of,lots of,plenty of,a great/ good deal of , a large / small amount / quantity of , a great/large/good number of等。
(4)只能与不可数名词搭配的限定词
有些限定词如a (little) bit of,a large amount of,a great deal of,(a) little,much,less,(the) least等只能与不可数名词 搭配。 a bit of water (a) little space a large amount of money less oil much noise (the) least oil

疑问限定词( Interrogative Determiner ): what , which , whose
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等)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 此把它归入后位限定词。
基数词(Cardinal Numeral)和序数词(Ordinal Number)
倍 数 词 ( Multiplicative Numeral ) 和 分 数 词 ( Fractional Numeral) 量词(Quantifier):a lot of,lots of,plenty of,a great/ good deal of , a large / small amount / quantity of , a great/large/good number of等。
b) 前位限定词包括 all,both,half; double,twice,three times等; one-third,two-fifths等; what,such (a/ an) (跨类限定词)。
限定词

我们还应该注意这两种用法的意思区别。 ①I will stay here for another three days. 意思 是“我还要在这里再呆三天”。“another+数 词+名词复数”这一结构的基本意思是“在原 有基础上的一个延续”。 ②I am always busy from Monday to Thursday, but I can come on three other days. 意思是“我 其他三天(Friday, Saturday, and Sunday)能 来”。“数词+other+名词复数”这一结构只 是单纯地表示“其他的…,另外的…”。
3、不定限定词some, any
⑴ 从与名词搭配来看,some和any均可以与不可 数名词和可数名词复数连用,表示“一些”。 some一般用在肯定句中;而any一般用在否定 句中。例如: ①Clint is busy. He always has some work to do. But John is lazy. He never does any work. ②Last night I was very hungry and I wanted some food to eat. But now I am not hungry and I don’t want any food to eat. ③I need some medicine to cure my cough. ④I want to buy some computer books. ⑤I don’t have any friend here.
this, these, that, those 既可以是形容词,放在名 词或one,ones之前作定语;也可以是代词,代 替名词或名词短语;还可以作副词,表程度。 如: I don’t like this book, I like that one. I don’t like this, it’s too difficult. Yesterday I bought a water-melon, this big.

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,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.
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, more, 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既可与不可数名词也可与复数名词搭配。例如: less money, less mistakes.

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
按照限定词和限定词之间的不同搭配位置,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)。
several hundred guests all other students 后 后 前 后 such a misfortune some such alloy 前 中 中 后 有上述诸例可以看出,中位限定词和前位限定词之间是相互排 斥的,即一个名词中心词之前不可并用两个中位限定词或两个前位 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,不可并列。但后位限定词 的使用却不受此限制。例如: his last two books 中 后 后 two more sheets 后 后 the first two chapters 中 后 后
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等)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 此把它归入后位限定词。
(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等能与单数名词和不可数名词搭配。 例如: this/that job this/that work

它们分为两种,即定冠词和不定冠词。
定冠词是“the”,用于特定的人、事物或场合。
例如,“the sun”(太阳)、“the moon”(月亮)、“the United States”(美国)等等。
不定冠词则是“a”或“an”,用于泛指或未知的人、事物或数量。

冠词的使用可以帮助我们更准确地表达所需要的信息。
其次,指示代词是另一种常见的限定词。
它们用于指出特定的人或事物,它们分为两种,即近指代词和远指代词。
近指代词包括“this”和“these”,用于指出靠近说话者的人或事物,例如,“this book”(这本书)、“these apples”(这些苹果)等等。

限定词限定词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INDEFINITE ARTICLE〕,零冠词ZERO ARTICLE〕物主限定词POSSESSIVE DETERMINER〕,my, your, his, her, our, your, their, one's, its.名词属格GENITIVE NOUN〕,John's, my friend's.指示限定词DEMONSTRATIVE DETERMINER〕,this, that, these, those, such.关系限定词RELATIVE DETERRMINER〕,whose, which.疑问限定词INTERROGATIVE DETERMINER〕,what, which, whose.不定限定词INDEFINITE DETERMINER〕,no, some, any, each, every, enough, either, neither, all, both, half, several, many, much, a few, a little, other, another.基数词CARDINAL NUMERAL〕和序数词ORDINAL NUMERAL〕倍数词MULTIPLICATIVE NUMERAL〕和分数词FRACTIONAL NUMERAL〕量词QUANTIFIER〕a lot of, lots of, plenty of, a great of, a good deal of, a large of, a small amount of, a quantity of, a great of, a good number of等.限定词与名词词组中心词之间有着某种固定的搭配关系;如果名词之前带有两个或两个以上的限定词,则限定词与限定词之间也有某种固定的搭配关系.本讲主要解决这两种搭配关系问题.1 限定词与三类名词的搭配关系限定词的选择决定于随后的名词的类别,是单数名词、复数名词,还是不可数名词.1〕能与三类名词搭配的限定词有些限定词如the, some, any, no, other, whose以及my, your等物主限定词和名词属格John's, my friend's〕等能与三类名词搭配.例如:the book, my book, my friend's book, John's book, any book, some book, no book, the other book, whose book, the books,my books, my friend's book, John's books, any books, some books, no books, the other books, whose books, the money, my money, my friend's money, John's 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an, 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 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, 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, more, 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an, the, zero; this, that, these, those; my, your, etc; Merry's, my friend's; some, any, no, every, each, either, neither, enough; whatever, whichever, 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, 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,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拆的,即一个名词中心词之前不可并用两个中位限定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, this 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 twenty 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, nosuch, few such, one such等;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. 本节所讲的"不定代词"多属于"名词性替代词"NOMINAL SUBSTITUTE〕,参见37.11〕many, 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 haven't 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'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 haven't done very many.Have you done much work today----Yes, I've 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 / if there'll 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.It's 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.We've had too much rain this spring. 这个春天我们已经有太多的雨.I'd 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 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, alittle表示"少"的意思,可用a few, a little, 既可用作限定词,也可用作不定代词.a few, a little 表示"少量",带有肯定意义.例如:Let's 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.I'm 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 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.I'm 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 little 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.You'll 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较少,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 aren't any letters for me.Are there any letters for meI 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 have some of these applesWould 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every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他单独去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.I'll 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:Neither student / 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.Every student failed 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 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 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:There 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.。
