谓语动词用单数的情况
1．动名词短语、不定式短语、名词性从句做主语，谓语用单数。如： Buying clothes is often a time-consuming job because those clothes that a person likes are rarely the cones that fit him or her. (1987年考研题) To understand the situation completely requires more thought than has been given thus far.
2．表示时间、距离、金额、重量、面积、体积、容积等度量的名词短语做主语时，谓语用单数。 Two weeks was too long Five times five makes twenty five 3．一般用and连接的两个单词或短语做主语时候，谓语用复数，但是下面用and
连接的主语表示一个概念，谓语用单数： law and order 法制 soap and water 肥皂水 a cup and saucer 茶杯碟子 fork and knife 刀叉 the needle and thread 针线 trial and error 反复尝试，不断摸索 horse and carriage 马车 time and tide 岁月 bread and butter 奶油面包 the ebb and flow 盛衰，潮涨潮落如： If law and order not preserved, neither the citizen nor his property is safe. A. is B. are C. was d. were 答案：A。
4．表示学科和某些疾病名称的名词是复数形式，作主语时候谓语动词用单数形式Linguistics is a branch of study on human language.
5．有些名词形式上是复数，意义上是单数，根据意义一致原则动词用单数 The chaos was stopped by the police The news is a great encouragement to us A series of debates between the lectures was scheduled for the next weekend.
6．用and 连接的成份表示一个单一概念时候，动词谓语用单数形式 Bread and butter is our daily food Time and tide waits for no man《和3同》
二．谓语用复数情况
1．由and, both …and, 连接的并列主语，和both ,a few, many ,several 等修饰语后面谓语动词通常用复数形式。 Few people know he and I were classmates when we were at college.
2．集体名词police, public, militia, cattle ,class ,youth后常用复数形式的动词 The Chinese people are brave and hardworking The cattle are grazing in the sunshine

三．谓语动词可用单数，也可以用复数的情况
1．就近一致原则这种情况下，谓语动词使用单数还是复数取决于最靠近该动词的主语的单复数，存在这种情况的主要由以下几种可能：
1）由连词either…or…; neither…nor…; whether… or…;not only…but (also) ;or 等连接的并列主语 Neither money nor fame has influence on me Not only you
but also he is wrong
2) 在倒装结构中，谓语动词与后面的第一个主语一致 Blocking the open-sided porch, framed by the enveloping fog, stands a tall grave-faced policeman. Just outside the ruins is a magnificent building surrounded by tall trees. Although a great number of houses in that area are still in need of repair, there has been improvement in the facili
2．主语带有（together/along）with, such as, accompanied by, as well as, no less than, except, besides, with, combined with, in addition to , including, together with 等等附加成分，谓语的数不受附加成分的影响仍然与主语保持一致Professor Taylor , with six of his students ,is attending a conference in Boston organized to compare current practice in the United States with those of other nations. The president of the college, together with the deans, is planning a conference for the purpose of laying down certain regulations. (1981年考研题) 3．关系代词做主语的定语从句中，谓语的数要与先行词一致。
如： Despite much research, there are still certain elements in the life cycle of the insect that are not fully understood. （1996年考研题） There are many valuable services which the public are willing to pay for, but which do not bring a return in money to the community. （1990年考研题）
4．一些表示数量的短语与名词连用时候，谓语动词的数取决于名词的数，名词是复数，谓语动词用复数，反之就用单数。这些短语包括：a lot of /lots of; plenty of/heaps of; half of; two-third (three-fourth…) of; eighty(ten, twenty…) percent; part of; rest of ; none of 等等 Two-thirds of people present are women Lots of damage was caused by the fire
5．集体名词作主语时，谓语动词的数取决于主语表示的意思和数，当表示整体时候，谓语动词就用单数，当强调集体中的个体时候，谓语动词就用复数。这些集体名词如：army, audience, band ,government ,group ,flock, police, public ,staff ,team ,troop. Crowd, firm, family 等等 The family is the basic unit of our society The family were watching the TV The audience was enormous The audience were greatly moved at the words
6．某些固定结构中主语与谓语的数：
第一组： a great many + 可数名词复数谓语用复数 a number of + 可数名词复数谓语用复数 the majority of + 可数名词复数谓语用复数
第二组； the number of + 可数名词复数谓语用单数 each/every + 可数名词复数谓语用单数 neither/either of + 可数名词复数谓语用单数 one and a half + 可数名词复数谓语用单数
第三组； more than one + 可数名词单数谓语用单数 many a + 可数名词单数谓语用单数
第四组； the greater part of a large proportion of 50% of one third of plenty of the rest of 谓语的数与of 后面的名词一致
第五组；(n)either…(n)or…. not only….. but also …… not …..but …… 谓语的数与主语的第二部分（即(n)or/ but also/ but引导的后面部分）一致.
注意比较： More students than one have been referred to
More than one student is going to buy this book
① Han Mei looks like her mother. 韩梅看起来像她的母亲。 般现在时中的第三人称单数形式 在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形 后加-s 或-es 。 （一） 什么是一般现在时？ 一般现在时的基本用法有哪些呢? 【一般现在时的功能】 1. 表示事物或人物的特征、状态。如： The sky is blue.天空是蓝色的。 2. 表示经常性或习惯性的动作。如： I get up at six every day.我每天六点起床。 标志词（时间状语）： always, every week (day, year, month …)， once a week, every …,sometimes, at …,on Sun day uauslly often,never,hardly __________________________________丿 3.表示客观现实。如： The earth goes around the sun.地球绕着太阳 （二）哪些主语是第三人称单数？现归纳总结如下: 单个人名、地名或称呼作主语；是第三人称单数。如 、人称代词 he, she, it He likes watch ing TV. he has lunch at twelve.

【发卷日期】2013年______月_______日 【学生姓名】__________________________ 一、如何把“单数句”变成“复数句”： 1、 “人称代词/物主代词/反身代词的单数形式”变成相应的“人称代词/物主代词/反身 代词的复数形式”。也就是说： 2、 be 动词变成相应的复数形式：am/is 变为___________，was 变为___________。 3、 不定冠词a/an 要________________________（去掉/保留），固定搭配除外。 例如：He is a boy.→They are boys. 4、 指示代词：this 变为__________________，that 变为__________________。 例如：This is a book.→These are books. 5、 man 和woman 作定语修饰可数名词时，要在"数"上与被修饰名词保持一致。也 就是说，当man 和woman 修饰可数名词．．．．时，在整个句子变成复数的情况下，它 们也变为复数形式：___________________________和___________________________。 例如：She is a woman teacher.→They are women teachers. 【注意】当名词修饰名词表“性质”时，不作变化。如：apple tree → apple trees 6、 单数句变复数句时，句中的形容词、副词、定冠词、特殊疑问词、介词短语和 感叹词等__________________________________________________（必须改变/保持不变）。 例如：Who is she? 她是谁？→ Who are they? 她们是谁？ 7、 有的英语单数句不可以变成复数句，必须根据题目的实际情况进行具体分析。 例如：My name is Kate. 我叫凯特。Three plus two is five. 三加二等于五。 8、 可数名词的单数形式要变为_______________形式。例如：It is a cat. → They are cats. book 书 → house 房子 → day 日子 → ruler 尺子 → bus 公共汽车 → waitress 女服务员 → dress 连衣裙 → glass 玻璃杯 → class 班 → box 盒子 → fox 狐狸 → dish 碟子 → brush 刷子 → watch 手表 → peach 桃子 → coach 教练 → 【注意】有些单词例外，它们本身就以字母s 结尾，如：news 新闻（不可数名词）
单数变复数专项练习 一、变化规则 1、一般情况下直接在词尾加s 例：book---books apple---apples orange---_________ tiger---_________ girl---__________ banana---_________ lemon---__________ pencil---_______ 2、以s,x,sh,ch结尾的单词，加es 例：bus---buses box---boxes fish---fishes beach---beaches class--- fox--- beach--- watch--- 3、以f或fe结尾的单词，把f或fe变成v加es 例：leaf---leaves knife--- (刀) wife--- （妻子） 4、以辅音字母加y结尾的单词，把y变i加es 例：fly---flies butterfly---_______ library---_______ baby---_____ puppy---______ 二、选择单词的适当形式填空，写在横线上。 1. It’s so hot. I want to eat an ________. Do you like ______?( ice-cream) 2.There are many_________(animal) in the zoo.I like .( giraffe) 3. ---Can I help you? ---Three _______ (doll),please. 4.

谓语动词单复数用法: 主谓一致是指： 1）语法形式上要一致，即单复数形式与谓语要一致。 2）意义上要一致，即主语意义上的单复数要与谓语的单复数形式一致。 3）就近原则，即谓语动词的单复形式取决于最靠近它的词语， 一般来说，不可数名词用动词单数，可数名词复数用动词复数。 There is much water in the thermos. 但当不可数名词前有表示数量的复数名词时，谓语动词用复数形式。 Ten thousand tons of coal were produced last year. 1 并列结构作主语时谓语用复数 Reading and writing are very important. 注意：当主语由and连结时，如果它表示一个单一的概念，即指同一人或同一物时，谓语动词用单数，and 此时连接的两个词前只有一个冠词。 The iron and steel industry is very important to our life. 2 主谓一致中的靠近原则 1）当there be 句型的主语是一系列事物时，谓语应与最邻近的主语保持一致。 There is a pen, a knife and several books on the desk.. There are twenty boy-students and twenty-three girl-students in the class. 2）当either… or… 与neither… nor，连接两个主语时，谓语动词与最邻近的主语保持一致。如果句子是由here, there引导，而主语又不止一个时，谓语通常也和最邻近的主语一致。 Either you or she is to go. Here is a pen, a few envelops and some paper for you. 3 谓语动词与前面的主语一致 当主语后面跟有with, together with, like, except, but, no less than, as well as 等词引起的短语时，谓语动词与前面的主语一致。The teacher together with some students is visiting the factory. He as well as I wants to go boating. 4 谓语需用单数 1）代词each和由every, some, no, any等构成的复合代词作主语，或主语中含有each, every, 谓语需用单数。 Each of us has a tape-recorder. There is something wrong with my watch. 2）当主语是一本书或一条格言时，谓语动词常用单数。 The Arabian Night is a book known to lovers of English. <<天方夜谭>>是英语爱好者熟悉的一本好书。 3）表示金钱，时间，价格或度量衡的复合名词作主语时，通常把这些名词看作一个整体，谓语一般用单数。(用复数也可，意思不变。) Three weeks was allowed for making the necessary preparations. Ten yuan is enough. 5 指代意义决定谓语的单复数
动词第三人称单数形式 主语有三单,动词也有三单,快点来习惯,体会在心里,一定要过关. 一、概念 动词第三人称单数：主语是第三人称单数，即谓语动词的发出者是it、she、he、可数名词单数、不可数名词等表示单数概念的词时，实义动词后面要加-s或-es。（注意：若主语不是第三人称单数形式，就直接用动词原形；若主语是三单，后有will等情态动词修饰时，动词也用原形。） 二、动词三单变化规则（只有一般现在时才有第三人称单数） 动词第三人称单数的变化规则及发音规律，同名词单数变复数大致相同，请认真观察。 1、大多数实义动词在词尾加“s”，在清辅音后发音为/ s / ，在浊辅音及元音因素后发音为 / z /。如：speak→speaks /s/ ; come→comes /z/ ; play→plays /z/ 2、以辅音字母加“y”结尾的动词，要先将“y”变为“i”，然后再加“es”，读/z/。 如：study→studies /z/ ; fly→flies /z/ 3、以“s，x，ch，sh”结尾的动词，在词尾加“es”，发音为/ iz / 。 如：teach→teaches /iz/ ; watch→watches /iz/ 4、以“o”结尾的动词,在词尾加“es”。 常出现的两个以“o”结尾的动词go和do后加“es”，读/z/ 。 如：go→goes /z/ ; do→does /z/ 5、记住最为特别的be的三单is ；have的三单是has。 [注意]（1）下面两个动词变三单时，原词的元音部分的发音发生了较大的变化，要记忆。 如：do/du:/ →does/d z/ ; say/sei/ →says /sez/ （2）以不发音字母“e”结尾的开音节词，如果尾音是[s]，[z]时，加“s”后字母“e”发音，与所加“s” 一起读做[iz]。如：close－closes [iz] 三、动词第三人称单数的句子结构。 1、肯定/否定句 三单+is +表语. 三单+动词第三人称单数+其他. 三单+is+not+表语 . 三单+doesn't +动词原形+其他. 2、一般疑问句 1）当谓语动词是be动词时，一般疑问句结构为“Is+三单+表语？”。它的肯定回答为：Yes, 三单+is. ;否定回答为：No，三单+isn't.。 2）当谓语动词是实义动词时，在肯定句句首加助动词does,即“Does+三单+动词原形+ 其他？”。它的肯定回答为：Yes，三单+does.;否定回答为：No，三单+doesn't.。 3、特殊疑问句 特殊疑问词+一般疑问句 四、要点 1）一定要看准句子的主语是第三人称而且还是单数； 2）经常与频率副词连用：always (一直，总是），usually（通常），often (经常），sometimes （有时），seldom (很少），hardly (几乎不），never (从不），once a day (一天一次），twice a week(一周两次），three times a month(一个月三次）。 如:I often speak Chinese. 我经常说汉语。
英语单词变复数规则 1.1 名词复数的规则变化 1.一般情况加 -s清辅音后读/s/ map-maps 浊辅音和元音后读 /z/ bag-bags /car-cars 2. 以s, sh, ch, x等结尾加 -es 读 /iz/ bus-buses/ watch-watches 3. 以ce, se, ze,等结尾加 -s 读 /iz/ license-licenses 4. 以辅音字母+y结尾变y 为i再加es 读 /z/ baby---babies 1.2 其它名词复数的规则变化 1）以y结尾的专有名词，或元音字母+y 结尾的名词变复数时，直接加s变复数。例如：two Marys the Henrys monkey---monkeys holiday---holidays 2）以o 结尾的名词，变复数时： a. 加s，如：photo---photos piano---pianos radio---radios zoo---zoos； b. 加es，如：potato--potatoes tomato--tomatoes c. 上述a和b两种方法均可，如zero---zeros / zeroes。 3）以f或fe 结尾的名词变复数时： a. 加s，如：belief---beliefs roof---roofs safe---safes gulf---gulfs； b. 去f,fe 加ves，如：half---halves knife---knives leaf---leaves wolf---wolves wife---wives life---lives thief---thieves； c. 上述a和b两种方法均可，如handkerchief: handkerchiefs / handkerchieves。 1.3 名词复数的不规则变化 1）child---children foot---feet tooth---teeth mouse---mice man---men woman---women 注意：由一个词加man 或woman构成的合成词，其复数形式也是-men 和-women，如an Englishman，two Englishmen。但German不是合成词，故复数形式为Germans；Bowman是姓，其复数是the Bowmans。 2）单复同形，如deer，sheep，fish，Chinese，Japanese ，li，jin，yuan，two li，three mu，four jin等。但除人民币的元、角、分外，美元、英镑、法郎等都有复数形式。如：a dollar, two dollars; a meter, two meters。 3）集体名词，以单数形式出现，但实为复数。例如： people police cattle 等本身就是复数，不能说a people，a police，a cattle，但可以说a person，a policeman，a head of cattle, the English，the British，the French，the Chinese，the Japanese，the Swiss 等名词，表示国民总称时，作复数用，如The Chinese are industries and brave.中国人民是勤劳勇敢的。 4）以s结尾，仍为单数的名词，如： a. maths，politics，physics等学科名词，一般是不可数名词，为单数。

谓语动词单复数的使用规则 一般every, each后用单数;all 后面的名词是复数. 1)名词性从句及不定式、动名词作主语时，谓语动词一般用单数形式。 【例如】 To finish the work in advance is what he wants. Smoking cigarettes is dangerous to your health What seems easy in theory is difficult in practice. What caused the accident is a complete mystery. 但是，what引导名词从句作主语时，其表语是复数形式时，系动词也可以是复数形式。 【例如】 What we badly need here are qualified teachers. 2)当主语是单数，后面跟着由including, with, together with, along with, like, in addition to, as well as, rather than, but, except, more than, accompanied by 等连接的短语时，谓语动词用单数。 【例如】 Mary as well as her sister likes listening to music. Doctor Richards, together with his wife and three children, is to arrive on the afternoon flight. My best friend rather than anyone else has got the first prize in the speech contest. 3) one, one of, every, everyone, everybody, each, many a, either, neither, no one, nobody, anyone, anybody, someone, somebody用作主语或修饰主语时，谓语动词用单数形式。 【例如】 Each man, woman and child has the same right. Many a student doesn’t like to do their homework. (many a student ＝many students) Either of students is going to compete for the president of the students’ union. More than one person was involved in the case. Neither of the young men who had applied for a position in the university ____. A) has been accepted B) have been accepted C) was accepted D) were accepted neither用作主语或修饰主语时，谓语动词用单数形式。此外，定语从句用过去完成时，主句应用一般过去时，故答案为C。
第三人称单数的动词在句子中的用法 动词，在英语众多词汇中堪称变脸的高手，遇到不同的人称、数和时态，它总会以不同的面孔登场。本期将重点向同学们介绍在一般现在时的句子中，当主语是第三人称单数时，英语动词的变化规则。 一般现在时的肯定句中，主语为第三人称单数的动词变化主要体现在词尾的变化上，其规律大体有三点： 1. 一般情况下，直接在动词词尾+s ，例如：get→gets; take→takes 2. 以s, sh, ch, x, o 结尾的动词，在词尾+ es，例如：tea ch→ teaches; fix→fixes; go→goes 3. 以辅音字母+ y 结尾的动词，变y 为i，再+ es，如：study→ studies; try→tries 除上述规律外，还应注意下面三点： 1. 动词have ，遇到主语是第三人称单数时，要用has；动词be 的第三人称单数形式是is。 2. 含有动词第三人称单数形式的句子变否定句时，要用doesn't + 动词原形，如：He goes to school at six in the morning. (变否定句)→ He doesn't go t o school at six in the morning. 3. 对含有动词第三人称单数形式的句子提问时，要用助动词does，如： She goes home at five every day. (对划线部分提问)→ When / What t ime does she go home every day? 综上所述，只要我们洞悉了英语动词第三人称单数形式的变化规则，在一般现在时的句子中，我们都能从容应对，客随主“变”了。 大家都知道，在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下： 一、人称代词he, she, it是第三人称单数。如： He likes watching TV. 他喜欢看电视。 She has lunch at twelve. 她十二点吃午餐。 It looks like a cat. 它看起来像只猫。
英语名词单数变复数的规则 1)单数名词加s: students, apples, bags, trees, books, brothers. 2)以s、x、sh、ch结尾的名词加es: glasses, boxes, brushes, matches. 3)以辅音字母加y结尾的名词，变y为i加es: cities, babies, enemies.4)以f或fe结尾的名词，多数变f为v加es: wives, knives.但有些词只加s: roofs, proof s, chiefs. 5)以o结尾的名词，有些加es: Negroes, heroes, tomatoes, potatoes.其它加s: radio s, zoos, pianos, photos. 6)不规则名词：foot→feet, goose→geese, tooth→teeth, child→children, man→me n, woman→women, sheep→sheep, deer→deer, mouse→mice. 7)某些外来词变复数：datum→data, medium→media, bacterium→bacteria, curriculum→curricula, criterion→criteria, phenomenon→phenomena. (um/on→a)analysis→analyses, basis→bases, crisis→crises, diagnosis→diagnoses.(is→es ) 8)复合名词变复数：以不可数名词结尾的复合名词无复数形式，如：homework.以man或woman为前缀的复合名词变复数，前后两个名词都变复数，如：manservant→mens ervants, woman student women students.其它复合名词变复数：grown up→grown ups,
