初三数词
中考对数词的考查主要集中在以下几个方面：
1、基数词与序数词的拼写、表达；
2、分数、小数、百分数、编号、时间、加减乘除运算等的表达；
3、数词加名词作主语时的主谓一致。
考查的主要形式是单项选择、语法选择。
二、基本概念
表示数目多少或顺序先后的词叫做数词。数词大概可以分为2类，一类表数目，称为基数词；一类表顺序―第几‖，称为序数词。
三、基础知识回顾
基数词
（1）基数词1-12是独立单词，需逐个记忆。
1 one
2 two
3 three
4 four
5 five
6 six
7 seven
8 eight
9 nine 10 ten 11 eleven 12 twelve
（2）13-19是由个位数加后缀―teen‖构成，注意其中13,15的拼写是thirteen和fifteen. （3）20-90的整十数字是由个位数加后缀―ty‖构成，注意其中20-50的拼写分别是twenty, thirty, forty 和fifty；80的拼写是eighty；
（4）其他非整十的两位数21-99是由整十位数加连字符―-‖，再加个位数构成，如：81 eighty-one；
（5）基数词三位以上的数词，在百位和十位数之间要用连词and。
如：691 six hundred and ninety-one 5,893 five thousand eight hundred
在基数词中只有表示―百‖―百万‖―千‖―千万‖的单位词，没有单独表示―万‖、―亿‖的单位词，而是用thousand（千）、million（百万）和billion（十亿）来表达:
如：100,100,100,100
thousand
million
billion
观察以下句子中关于数词的表达：
1)There are thousands of ants around the sugar.
2)There are about six billion people in the world.
表达概数用：hundreds/thousands/millions/billions of + n. ，译为：成百的/成千的/成万的…，表达精确的数用：one/two/three...+hundred/thousand/million/billion + n.

初中英语语法--数词
数词 （一）分类：数词有基数词和序数词两种。可以作句子的主语、宾语、表语和定语。 1、基数词：表示数目的词叫基数词。 常用的基数词有：
[注]：(1)百位与十位之间要加and；百位为0的话，就加在百位和个位之间。 108→one hundred and eight, 146→one hundred and forty-six, 500→five hundred , 1001→one thousand and one, 1813→one thousand eight hundred and thirteen. 一千：1000→one(a)thousand, 一万：10,000→ten thousand, 十万：100,000→one hundred thousand , 百万：1,000,000→one million, 千万：10,000,000→ten million, 亿：100,000,000→one hundred million, (2)英语用千、百万等单位计数，大数字从右向左看, 每隔三位划一逗号，倒数第一个逗号之前要用thousand，倒数第二个逗号之前要用million，倒数第三的逗号之前要用billion 表示。 3，456，789 three million four hundred and fifty- six thousand seven hundred and eighty-nine 6，004，001 six million four thousand and one (3) hundred、 thousand、 million表示确切的数时，不加s。如：five hundred(五百)，加S时表示不确定的数，后面必须要有of，前面可以加上some, many, several等词，翻译为：“成…上…”。hundreds of(成百上千的)，thousands of(成千上万的), millions of(成百万的) 2、序数词：表示顺序的数词叫序数词。 ①英语的序数词基本变法： (1) 一般在基数词后加th,(2)-ve结尾的改为-fth,(3)-ty结尾的改为-tieth,(4) 熟记特殊词。
数词用法讲解及练习
数词 I.定义与分类 数词是指表示数目多少或顺序先后的词。表示数目多少的数词叫基数词，如one, five, ten, thirty, sixty-five 等；表示顺序先后的数词叫序数词，如first, sixth, tenth, twenty-first 等。数词用法相当于名词和形容词，在句中可用作主语、宾语、表语、定语、同位语等。 II. 基数词 1. 英语中没有“万”这个读数单位，要表示汉语中的“万”，英语需借用thousand一词，如“一万”用“十个千”表示(ten thousand)，“十万”用“一百个千”表示(one hundred thousand)。 2. 用作基数词单位的hundred, thousand, million, billion 通常不带复数词尾-s，但若用于表示数百、数千、数百万这样的泛指，则用复数。如： About two thousand people died in the earthquake. 大约有两千人在地震中丧生。Thousands of people go to the seaside every year. 每年成千上万的人到海滨去。 3. 表示整十的基数词用复数形式可以表示人的大约岁数或年代。如： He is in his early twenties. 他才二十出头(from 。 This took place in the 1930s. 这事发生在20世纪30年代。 III. 序数词 1. 许多序数词是由相应的基数词后加词尾-th构成的，如four / fourth，six / sixth，ten / tenth，sixteen / sixteenth，但是nine变为序数词是ninth，而不是nineth。 2. twentieth, thirtieth, fortieth 等表示整十的序数词，由相应的基数词将词尾y改为ie，再加-th 构成。 3. first, second, third 通常可缩写为1st, 2nd, 3rd。凡是以th结尾的序数词可缩写为“基数词+th”：4th, 5th, 9th, 11th, 60th, 128th等。 4. 非整十的多位数，将个位数变成序数词即可：twenty-first(第21)，thirty-sixth(第36)，ninety-ninth(第99)，three hundred and sixty-fifth(第365)等。 5. hundred, thousand, million 等序数词形式为hundredth, thousandth, millionth 等。 6. 序数词前通常要用定冠词，但表示考试或比赛等的名次时，通常可省略其前的定冠词。如： My room is on the second floor and his on the third. 我的房间在三楼，他的房间在四楼。 He was (the) third in the exam. 他考试得了第三名。 注：有时序数词前不用定冠词，而用不定冠词，表示次第在原有基础上的增加。如：We’ll have to do it a second time. 我们得再做一次(from 。 序数词前用定冠词和不定冠词的区别在于：定冠词表特指，不定冠词表泛指，有类似another 的意思，但比another 的意思更明确。 IV. 分数、倍数、小数和百分数 1. 分数。 (1)分数由基数词和序数词构成：分子用基数词，分母用序数词，当分子超过“1”时，分母用复数。如： two thirds=2/3 three fifths=3/5 注：1/2 通常读作 a [one] half，一般不读作a second；1/4 可读作 a [one] fourth，也可读作 a [one] quarter。

2、序数词 [品味中考] 1．“When is your mother’s birthday, Tina?”“It’s On July the_________.” A．twenty B．ninth C．five (贵阳卷) 2．－We’ll be back for our school’s________ anniversary ceremony. (黄冈卷) －I see.

初中英语知识点归纳汇总
初中英语知识归纳总结 第一课时名词 一、概述 1、名词的属性：表示人或事物的名称抽象概念的词叫名词。 2、名词分普通名词和专有名词。普通名词是表示某一类人或事物，或某种物体或抽象概念的名称。如：teacher, desks, plates, milk, box等，专有名词表示某一特定的人、事物、地方团体、党派、国家机关、语言、节日等专用的名称。（运用）如：China, Chinese, Saturday, June, Green, Beijing, Olympic等。（专有名词的第一个字母要大写） 二、可数名词与不可数名词 1、可数名词是指表示人或事物，可以用数来计量的名词，有单复数之分。如：glass-----glasses; book---- books 2、不可数名词是指所表示的事物不能用数来计量。 如：paper, rice, water , milk, tea等。 3、有些名词在特定情况下由不可数变为可数名词。 Light travels faster than sound; (light：光线，不可数) The lights are on. (light：灯，可数) 4、不可数名词的量的表示 不可数名词一般无法用数来计算，前面不能用a或an或数词来表示数量，它的量往往借助于容器来表示。 如：a glass of milk ------ four glasses of milk a piece of paper ------two pieces of paper a bag of rice ------three bags of rice 三、可数名词的复数形式（识记、运用） 1、可数名词在应用时有单复数之分，单数变复数有规则变化和不规则变化两种。 规则变化 policeman---policemen; man---men; woman---women; tooth---teeth; foot---feet; sheep---sheep; deer---deer; Japanese--- Japanese; Chinese --- Chinese; fish --- fish 四、名词所有格（运用） 名词的所有格是表示所有关系的形式，它也有构成上的变化。 1、单数名词变所有格，只需在词尾加’ s; 2、复数名词的词尾已有s，只需加’即可； 3、复数名词的词尾若没有s ，则应加’ s ; 4、如果表示某人或物为两人所共有，则在第二个人后面加’ s ; 如：Da Mao and Xiao Mao’s room 如果不是两人共有，则在每个人后面都加’ s; 如：Li Lei’s and Tom’s mother 5、名词所有格结构通常用于表示有生命的名词，或表示时间、距离、地点等，而表示无生命名词的所有关系则用“of”表示。 如: the windows of house the picture of the family

初三英语下学期 中考英语 语法填空训练单元提优专项训练
初三英语下学期中考英语语法填空训练单元提优专项训练 一、英语语法填空汇编 1．语法填空 Chen Yujie studies at a boarding school in Ningbo, Zhejiang. She used to go back to her home in Cixi every week ________ （get） money from her parents. It was not a short ride home and the trips were tiring. Chen hoped her parents could put the money on a bank card, ________ she didn't have to travel so often. She decided to discuss ________ with her parents during TV time after dinner. "It's usually the most relaxing time for our family," said Chen. She ________ the right time. After a few turns of lobbying（游说）, her parents ________ agreed with Chen. For most teenagers like Chen, talking to parents can be difficult or even worrying. So they have to choose a right time. American magazine Highlight recently surveyed 1,521 ________ （kid）aged 6~12 in the country, asking questions like" When you want to talk to your parents about something important, when is ________ best time to do it?". Results show that American kids seem to know when their parents are most receptive（乐于接受的）. Mealtime is discovered to be their favourite time to talk to their parents. Bedtime comes ________ （two）, followed by time spent in the car. ________ （China）teenagers seem to have a similar tendency（倾向）towards the problem. A newspaper in Zhejiang did a survey ________ it. The result shows most teenagers in the city would choose mealtime to talk to their parents. So do you have anything to talk to your parents? Choose a good time. 【答案】 to get；so；it；chose；finally；kids；the；second；Chinese；of 【解析】【分析】本文介绍了青少年和父母交流的问题，对大多数青少年来说，与父母交谈可能很困难，甚至令人担忧。所以他们必须选择正确的时间。 （1）句意：她常常每周回到在慈溪的家为了从父母那里取钱。此处是不定式做目的状语，为了，故填to get。 （2）句意：陈希望她的父母可以把钱打到银行卡上，这样她不用经常回家了。根据put the money on a bank card和she didn't have to travel so often可知，把钱打到银行卡上的结果是这样她不用经常回家了，故此处是连词表示结果，so是连词，故填so。 （3）句意：她决定晚饭后看电视时和她的父母讨论这件事。discuss后缺少宾语，it指代把钱打到银行卡上这件事，故用it指代一件事，故填it。 （4）句意：她选择了正确时间。此处缺少谓语动词，根据下文choose mealtime to talk to their parents选择用餐时间和父母交谈，可知是选择时机，choose是动词，描述过去用一般过去时，choose的过去式是chose，故填chose。 （5）句意：在几次游说下，她的父母终于同意了陈的意见。副词修饰动词agreed，finally，终于，是副词，故填finally。 （6）句意：美国杂志最近重点调查了该国15216名6-12岁的儿童。基数词1521后是名词复数，故填kids。

初中英语语法之数词
初中英语语法-数词及练习 一、内容概述 表示数目和顺序的词叫数词。数词可分为基数词和序数词两类 二、重点知识归纳及讲解 (一）基数词 基数词用来表示数目，或者说表示数量的词叫基数词。最基本的基数词如下表所示。 1 one 11 eleven 100 a hundred 2 two 12 twelve 20 twenty 1000 a thousand 3 three 13 thirteen 30 thirty 1，000，000 a million 4 four 14 fourteen 40 forty 10，000，000 ten million 5 five 15 fifteen 50 fifty 100，000，000 a hundred million 6 six 16 sixteen 60 sixty 1，000，000，000 a billion 7 seven 17 seventeen 70 seventy 8 eight 18 eighteen 80 eighty 9 nine 19 nineteen 90 ninety 10 ten 说明： 1．13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen和fifteen。2．20—90由个位数加后缀-ty构成，注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。 3．其它非整十的两位数21—99是由整十位数加连字符“-”，再加个位数构成。如81 eighty-one。4．101—999的基数词先写百位数，后加and再写十位数和个位数.如691 six hundred and ninety-one。 5．1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。 如：5893 five thousand eight hundred and ninety-three。在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和million（百万）来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。 7．多位数的读法： 1）1000以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand（千），第二个间隔或逗号前是million（百万），第三个间隔或逗号前是a thousand million或a billion(十亿)。 2）每隔三位分段以后就都成了101—999。读的时候十位数（或个位数）的前面一般要加and。如：888，000，000读作：eight hundred and eighty-eight million。

初三英语知识点总结有哪些
初三英语知识点总结有哪些 ----WORD文档，下载后可编辑修改---- 下面是小编收集整理的范本，欢迎您借鉴参考阅读和下载，侵删。您的努力学习是为了更美好的未来！ 初三英语知识点总结英语名词分可数的和不可数两种。可数名词指一般动物和事物，如“Man/ friend/ driver/ student/ dog/ cat/ boat/ egg/ gun/ hand/ head/ lamp/ road/ table/ car ”等等。 可数名词有两个数，即单数和复数。单数名词可以和不定冠词“ a/ an”或其他名词限定词(determiners)连用;复数名词可以和数目词，如“many/ a few/ some/ a lot of”等连用。 不可数名词指物质名词(material nouns)和抽象名词( abstract nouns)，如：“air/ butter/ grass/ money/ sand/ water/ carefulness/ joy/ peace”等等。不可数名词可以和数量词，如“much/ a little/ little/ a great amount of”等连用。不可数名词只有单数，没有复数“-s”的形式。 有些人对名词数的概念不很清楚，对数目词(expressions of number)和数量词(expressions of quantity)也有些混乱，结果把数目词用在不可数名词之前或随意在不可数名词后面加上复数词尾“-s”，这些都是语法上的错误。例如： ① Our workshop has ordered some n ew equipments from Germany. 虽然有些人把 equipment(配备)当成可数名词，但是它是不可数的，不可有“-s”。 ② My teacher gave me some sound advices. 应该是“advice”。 ③ Do you have any special informations for me? “Information”才对。 ④ Most furnitures in my house are made of wood. 应该是“furniture......is......” ⑤ Today, I have many new works to do. 必须是“a lot of new work”才是。 ⑥ Don't walk on the grasses. 应该用“grass”。
