加减乘除表示法
❖ 1. “加”用plus，and或add表示； ❖ “等于”用is，make，equal等词表示。 ❖ 2+3= 可表示为：How much is two plus
❖ 在我们班她是第二名。（作表语）
序号表示法
（1）单纯的序号，可在基数词前加number,简写为No.。 如：No.1 第一号
（2）事物名词的序号表达法有所不同： ❖ ①对于一些小序号可用序数词也可用基数词表达，形式分别
为：the + 序数词 + 名词 / 名词 + 基数词。 ❖ 如：第一次世界大战可以表示为 ❖ the First World War = World War One, ❖ Lesson 8 = the eighth lesson ❖ ②对于一些大序号我们通常只用一种表达法， ❖ 即名词 + 数词。 ❖ 如：501号房间表示为 Room 501, ❖ 538路公共汽车表示为 Bus 538。 ❖ ③可用a / the + number + 基数词 + 名词。 ❖ 如：a No.5 bus一辆五路公共汽车， ❖ the No.8 bus那辆8路公共汽车。
They produced more products in 2001 than those in 2000 by twice.
The production of grain has been increased by four times this year.

知识讲解
序数词
把1－99的序数词也分为四个类： 1. 第一类 first (1st), second (2nd), third (3rd) 这类序数词只有三个，在整个序数词里面是特殊的，需要逐个地硬记下来。 在括号里的是缩写形式，均在阿拉伯数字后面加上相应序数词的最后两个字 母构成，以下各类与此相同。
知识讲解
基数词
4. 第四类： 这一类词可以看成是一种合成词，其结构方式是：用十位整数加上个位整数， 其间用连字符号“－”连接，表示“几十几”。这类基数词的变化是规则的。 twenty-one, forty-six, seventy-eight, ninety-five
知识讲解
基数词
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。 200 two hundred 3,200 three thousand and two hundred 1, 526,200 one million, five hundred and twenty-six thousand and two hundred thousands of billions of

基数词
把100以内的基数词分为四类： 1. 第一类：
one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve 这一类共计十二个单词，在结构上与其他的基数词相比较是特殊的，这些词 对学好其他的基数词和序数词都是及其重要的。
知识讲解
序数词
4. 第四类 thirty-first (31th)，sixty-second (62nd)，eighty-seventh (87th) 这类表示“第几十几”的序数词，十位数不变，仅把个位 上的基数词变成序数词就可以了。

初中英语语法专题复习之数词语法英语数词语法是英语学习中非常重要的一部分，它涉及到数字的读法、写法以及数词的分类和使用。

在学习英语数词语法时，我们需要掌握基本的数词分类、基数词和序数词的用法，以及数词的单位和表示数量的单词。

一、英语数词的分类英语数词可以分为基数词和序数词两类。

基数词:表示数目多少的数词叫基数词，例如:“one”、“two”、“three”等。

基数词一般是单数形式，但以下情况，常用复数:a、与of短语连用，表示概数，不能与详细数目连用，如scores of。

序数词:表示顺序的数词叫序数词，例如:“first”、“second”、“third”等。

序数词一般是以-th结尾的形容词或名词的形式，例如“first”就是“第一”，“second”就是“第二”。

需要注意的是，有些数词既可以作为基数词，也可以作为序数词使用，例如“ten”可以作为基数词“ten”和序数词“tenth”使用。

另外，有些数词既可以表示数量，也可以表示顺序，例如“three”既可以表示“三个”，也可以表示“第三天”。

二、英语数词的用法英语数词在使用时有以下用法:表示数量:基数词可以表示数量的多少，例如:“one”表示“一个”，“two”表示“两个”，“three”表示“三个”等。

表示顺序:序数词可以表示顺序，例如:“first”表示“第一”，“second”表示“第二”，“third”表示“第三”等。

表示倍数:可以用基数词的倍数形式来表示倍数，例如:“two times”表示“两倍”，“three times”表示“三倍”等。

表示约数:可以用基数词的约数形式来表示约数，例如:“ten”表示“十个”，“twenty”表示“二十个”等。

表示价格:可以用基数词来表示价格，例如:“one dollar”表示“一美元”。

表示距离:可以用序数词来表示距离，例如:“fifth floor”表示“第五层”。

表示时数:可以用序数词来表示小时数，例如:“sixth hour”表示“第六小时”。

四ห้องสมุดไป่ตู้年、月、日、年代的表达

• • • • • • •
4) 约数 a. 大约用about, nearly, some, around He is coming around five o’clock. b. 多于，超过 用over, more than The bridge is over 1500 meters long. c. 少于，不超过 用less than She is less than twenty years ago.
2）倍数的表达法 a. 倍数+ as...as • 倍数+as...as（意为“A是B的几倍”，多用于对 客观事物的比较。） • Asia is four times as large as Europe.亚洲有欧洲 的四倍大。 • This dictionary is twice as heavy as that one.这 本字典有那本字典的两倍重 b. 倍数+比较级形式+than • 倍数+（形容词/副词）比较级形式+than，意为“ 增加（多）几倍”。 • This type of car uses three times more petrol than that type does.这种汽车比那种汽车的耗油 多三倍。 • The house is twice larger than that one.这间房子 比那间大两倍。
