英语名词用法

英语名词用法 、英语名词可分专有名词和普通名词两大类: 1、专有名词是个别的人、地、物、团体、机构等的专用名称。 专有名词中实词的第一个字母要大写。 如:Beijing, Tom, the People?s Republic of China(中华人民共和国) 专有名词如果是含有普通名词的短语,则必须使用定冠词the。如:the Great Wall(长城) 姓氏名如果采用复数形式,则示该姓氏一家人(复数含义),如:the Greens( 格林一家人)。 2、普通名词是许多人或事物的共有名称。如:pupil, family, man, foot. 普通名词又分为可数名词和不可数名词。 ?可数名词是可以用简单的数词进行计数的名词,如: box, child, orange; ?不可数名词是不可以用简单的数词进行计数的名词。如:water, news, oil, population, information . 2、英语可数名词的单复数:英语可数名词有单数和复数两种形式。 1、名词由单数变复数的基本方法如下: ?在单数名词词尾加s。如:map ? maps,boy? boys,horse? horses, table? tables. ?s,o,x ,sh,ch结尾的词加es.如:class?classes, box?boxes, hero?heroes, dish?dishes, bench?benches. [注]:少数以o结尾的词,变复数时只加s。如:photo?photos, piano?pianos. ?以辅音字母加y结尾的名词,变y为i,再加es。如:family?families, city?cities, party?parties. ?以f或fe结尾的名词,变f或fe为v,再加es。如:shelf?shelves, wolf?wolves, life?lives, knife?knives. 2、不规则变化:man?men, woman?women, sheep?sheep,tooth?teeth, fish?fish, child?children, ox?oxen, goose?geese 不可数名词一般没有复数形式,说明其数量时,要用有关计量名词。如:a bag of rice?two bags of rice, a piece of paper?three pieces of paper, a bottle of milk?five bottles of milk. 3、名词所有格: 1、 名词所有格表示所属关系,相当于物主代词,在句中作定语、宾语或主语。其构成法如下: (1)表示人或其它有生命的东西的名词常在词尾加?s。如:Childern?s Day(儿童节), my sister?s book(我姐姐的) (2)以s或es结尾的复数名词。只在词尾加?。如:Teachers? Day(教师节) (3)有些表示时间、距离以及世界、国家、城镇等无生命的名词,也可在词尾加?s. 如: today?s newspaper(今天的报纸), ten minutes? break(十分钟的课间休息), China?s population(中国的人口). (4)无论表示有生命还是无生命的东西的名词,一般均可用介词of短语来表示所有关系。如: a fine daughter of the Party(党的好女儿). 2、[注解]: ? „s还可以表示某人的家或者某个店铺,如:my aunt?s(我阿姨家), the doctor?s(诊所) ? 两人共有某物时,可以采用 A and B?s 的形式,如:Lucy and Lily?s bedroom(露西和丽丽合住的卧室) ? “of+名词所有格/名词性物主代词”,称为双重所有格,如:a friend of my father?s(我父亲的一位朋友), a friend of mine(我的一位朋友) 4、名词或代词作主语时和谓语之间的单复数的一致问题: 1、谓语和谓语基本保持单复数的一致,即:主语是可数名词单数或不可数名词时,谓语动词用单数形式:如:The computer was a great invention.(计算机是个了不起的发明)The water in the glass is very cold.(玻璃杯里的水很冷) 2、集体名词(如family, class, team, group, row, police, school等)做句子主语时, ? 如果表示整体概念,则谓语用单数形式,如:Class Three is a very good class.(三班是好班) ? 如果表示其中的所有成员时,则谓语用复数形式,如:Class Three have a map of China.(三 班有张中国地图) 3、Chinese, Japanese, fish, sheep, people等表示单个时谓语用单数,表示许多时,谓语用复数。如:There is a sheep in the yard.(院子里有只绵羊) / There are some sheep in the yard.(院子里有一些绵羊) 4、maths, news等虽然有s结尾,但不是复数,因此谓语仍用单数:The news is very exciting. (这个消息令人兴奋) 5、glasses, shoes, socks, trousers, gloves等名词往往用复数形式,故谓语用复数。如: The trousers are very cheap and I want to take them.(裤子很便宜,我想买) 6、a lot of 后跟名词复数时谓语用复数形式,跟不可数名词时谓语用单数形式。如:A lot of students are playing baseball now.(现在有许多学生在打垒球) A lot of time was wasted on that work.(大量的时间花在了那个工作上)(被动句) 7、and 连接两个名词做主语时,谓语原则上用复数,但是两个名词若构成一个整体事物时,谓语则用单数。如:The teacher and his son are picking apples now.(老师和他的儿子在摘苹果) / Fish and chips is very famous food. (鱼和薯条是一种出名的食品) 8、 there be 句型中be的单复数一般由靠近的名词决定。如:There is a table and four chairs in the room.(房间里有一张桌子和四张椅子) 9、用both…and…连接两个事物做主语时,谓语一般用复数。如:Both you and I are required to be here tomorrow.(你和我明天要求都来) 10、主语中含有with的短语时,谓语单复数由with之前的人物决定。如:A woman with a 7-year-old child was standing at the side of the road. (一名妇女带着一个七岁的孩子(当时)就站在路边) 11、either…or…或者 neither…nor…连接两个人物做句子主语时,谓语采用就近原则。如:Either you or he is right.(要么是你对,要么是他对。/你和他有一个人是对的) / Neither you nor I am going there.(你和我都不打算去那里) 12、表示一段时间或长度概念的复数名词做主语时,谓语一般用单数。如:Two months is not a short time.(两个月不是个短时间)Two thousand kilometers is quite a long distance(距离).(两千千米是相当长的一段距离) 13、主语中含有half of… / (three quarters)of… / all (of) the ….等词语时,谓语的单复数由名词确定,如:Over three quarters of the information on the Internet is in English.(因特网上四分之三以上的信息是用英语写的) / A third of the students were playing near the lake.(学生的三分之一(当时)正在湖边玩耍) / All of the water in these rivers has been polluted.(这些河流中的水已经被污染了)(被动句) 但是,population一词又有特殊情况: What?s the population of China?(中国人口是多少,)(句子用单数) / Three quarters of the population in this city are Arabs(阿拉伯人).(这个城市四分之三的人口是阿拉伯人)(句子用复数) 5、部分名词用法辨析: 1、sport、game、match、race 的区别:sport通常指“户外运动”,以锻炼为主,概念较大;game意思是“运动、比赛”,不管户内户外还是脑力体力,指以胜负为主的运动;match意为“竞赛、比赛”,多指正式比赛;race主要表示“赛跑、赛马、赛车”。如:People all around the world enjoy sports.(全世界的人都喜爱运动) / The 2008 Olympic Games will be held in Beijing.(2008奥运会将在北京举行)(被动句) / Our school football team won the league match(联赛).(我们学校足球队取得了联赛冠军) / They were strong and won the boat race.(汤他们很棒,赢得了划艇比赛) 2、festival、holiday、vacation的区别:festival“节日”,指喜庆的日子或持续一段时间的文娱活动;holiday(假日、休息日),指法定假日或风俗习惯,复数可以表示一个较长的假期;vacation“假期”,指学习 或工作中一段长时间的休息。如:The Shanghai Television Festival will be held next month.(上海电视节将在下个月举行) / Sunday is a holiday and most people do not work.(星期天是个假日,多数人不工作) / What are you going to do during the summer vacation/holidays?(在暑期你打算做什么事情,) 3、journey、tour、trip、travel的区别:journey指在陆地上(或海上或空中)进行的长途旅行,不知终点,含有辛苦的意思;tour指途中作短期逗留的巡回旅行,强调游览多处,常用来指观光等;trip通常指往返定时的短途旅行,如出差度假等;travel多指长期或长途的观光旅行,尤其指到国外,没有明确目的地,也作不可数名词,指旅行这一行为。如:He made up his mind to make the journey to Dunhuang.(他拿定主意要去敦煌旅行)/ He has gone on a walking tour.(他步行观光去了) / He took several trips to Shanghai last yeaar.(去年他去了上海好几次) / Did you go to Santiago(圣地亚哥) during your travels?(旅行期间你去圣地亚哥了吗,) / Travelling through thick forests is dangerous.(在密林里边穿行是很危险的) 4、sound、noise、voice的区别:sound指各种声音;noise主要指“噪音”;voice指人的“嗓音”。如:The noise of the street kept me awake in the night.(街上的喧嚣声让我彻夜难眠) / All of a sudden there was the sound of shots and a cry.(突然间传来几声枪响和一声尖叫) / The singer has lost her ringing voice as a result of a bad cold.(因为感冒的缘故,这个歌唱家失去了她银铃般的嗓音) 5、fish的问题:指许多条鱼且不管种类时,用fish,单复数相同;fishes 指许多种类的鱼;fish指“鱼肉”时是不可数名词。如:There are many kinds of fishes in the pool. (池子里有很多种类的鱼)/ I prefer fish to meat.(与肉相比我更喜欢鱼)
