8、有名词中实词的第一个字母要大写。如：Beijing, Tom, the Peoples 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,则表示该姓氏一家人(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
9、：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：classclasses, boxboxes, heroheroes, dishdishes, benchbenches.注：少数以o结尾的词,变复数时只加s。如：photophotos, pianopianos.以辅音字母加y结尾的名词,变y为i,再加es
10、。如：familyfamilies, citycities, partyparties.以f或fe结尾的名词,变f或fe为v,再加es。如：shelfshelves, wolfwolves, lifelives2、不规则变化：manmen, womanwomen, sheepsheep,toothteeth, fishfish, childchildren, oxoxen, goosegeese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 ricetwo bags of rice, a piece of paperthree pieces of paper,
11、 a bottle of milkfive 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：Childerns Day(儿童节), my sisters book(我姐姐的书)(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：todays newspaper(今天的报纸), ten minutes break(十分钟的课间休息),Chinas

13、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. The water in the glass is very cold.2、集体名词(如family, class, team, group, row, police, school等)做句子主语时,1如果表示整体概念,则谓语用单数形式,如：Class Three is a very good class.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.3、Chi
14、nese, 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. / There are some sheep in the yard4、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. 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
15、.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. A lot of time was wasted on that work. (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./ Fish and chips is very famous food. 8、 there be 句型中be的单复数由靠近的名词决定。如
16、：There is a table and four chairs in the room.9、用bothand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.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. 11、eitheror或者 neithernor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
17、right. / Neither you nor I am going there.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. Two thousand kilometers is quite a long distance(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 Engli
18、sh / A third of the students were playing near the lake. 但是,population一词又有特殊情况： Whats the population of China? / Three quarters of the population in this city are Arabs(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”
19、,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、va

23、nging voice as a result of a bad cold. 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. / I prefer fish to meat.三、代词：1、代词的分类：英语中代词分为：人称代词、物主代词、反身代词、指示代词、关系代词、疑问代词、连接代词和不定代词等等。2、人称代词：人称代词代替人和事物的名称,分为主格和宾格两种形式。第一人称单数第二人称单数第三人称单数第一人称复数第二人称复
