高考复习数词PPT课件

语法复习十六：数词高考重点要求：1．掌握基数词、序数词、分数词、倍数、百分数、年月日、钟点、年龄、序号的基本用法。

2．掌握不定数量词、约数词的表达方法。

数词在各个题项中，单选、阅读、听力、写作中发挥着很强的作用，往往用以说明事实的精确性和可信性。

数词是由两大部分构成的即基数词和序数词，而其他数字表示法如分数，小数等均由这两大部分的不同组合而构成。

高中高考英语数词在英语学习中，数词的使用是不可避免的一部分，尤其在高考英语中，数词的正确使用更是关键。

本文将探讨高考英语中数词的使用规则和注意事项。

一、数词的定义和分类数词是表示数量或顺序的词，可以分为基数词和序数词两类。

基数词表示数量，例如one, two, three等。

序数词表示顺序，例如first, second, third等。

二、基数词的使用1、21-99之间的数词，十位数和个位数之间用连字符连接，例如21twenty-one，35thirty-five。

2、100以上的数词，可以用hundred/thousand/million等词和连字符连接表示，例如150one hundred and fifty，2000two thousand。

3、表示不确定数量时，用some/many等词，例如There are some people in the room.三、序数词的使用1、1-19之间的序数词，在词尾加-th，例如sixth第六，nineteenth 第十九。

2、20-90之间的序数词，十位数和个位数之间用连字符连接，然后在词尾加-th，例如twenty-first第二十一点钟，sixty-sixth第六十六页。

3、100以上的序数词，可以用hundred/thousand/million等词和连字符连接表示，然后在词尾加-th，例如one hundred and first第一百零一点钟。

四、注意事项1、注意区分基数词和序数词，不要混淆使用。

2、注意使用正确的形式和语法结构来表示数量和顺序。

3、注意使用适当的词汇和表达方式来描述数量和顺序。

数词在高考英语中是非常重要的知识点之一，要想在高考英语中取得好成绩，必须熟练掌握数词的用法并灵活运用。

一、试卷概述本试卷为高中高考化学模拟试卷，旨在帮助学生了解和掌握高考化学的考试形式和内容，提高应试能力，为即将到来的高考做好准备。

试卷包含选择题、填空题、解答题等题型，涵盖了高中化学的基础知识、重点和难点内容，难度适中，符合高考化学的难度要求。

会考复习四数词一概念数词分为基数词和序数词。

二基数词表示数目的词为基数词。

千以上的数字，先从后向前数，每三位用一个“，”隔开，第一个“，”表示thousand千，第二个表示million百万，第三个表示billion亿，然后一节节再用几百几十几的方法表示。

在这类数词中hundred, thousand, million, billion等词一般都用单数形式。

2.基数词的用法1）在表示具体数目或several修饰时，hundred，thousand，million，billion等用单数；在表示“数百”“数千”“数百万”等不确定数目时，在hundreds，thousands，millions，billions 等后接“of+名词复数.five thousand students 五千个学生several hundred year's ago几百年前thousands of metres 数千米3）dozen和score的复数形式应注意以下几点：①dozen表示：一打，十二个，score表示：二十；②当dozen与数词，或many，several等连用时，不加“s”，所修饰的名词前常省去“of’；score则不然。

two dozen pencils两打铅笔two score of pencils四十支铅笔dozens of people=scores of people许多人③当后面的名词前有"these"，“those"，“them"，" us"等词时, dozen后应加"of "。

a dozen of these peopletwo dozen of themthree score and ten people中不加of(七十人)三序数词表示顺序的数词为序数词。

序数词前面一般加定冠词the，表示“第几”，加不定冠词，则意为“又一,再一”the two hundredth the eighteenthI like the film very much, so I want to see it a second time.四分数、小数和百分数的表达1. 分数由基数词和序数词合成，分子用基数词，分母用序数词，当分子大于1时，分母的序数词要用复数，表示几又几分之几，用and连接形式1/3：one(a)third 2/3：two thirds three-sevenths：七分之三特殊的表达①1/2：one(a)half 1/4：one(a)quarter／one(a)fourth 3/4：three quarters②分子与分母之间加in或out of,分子在前，分母在后，分子分母都用基数词one in ten：十分之一five in eight：八分之五one out of ten：十分之一five out of eight：八分之五2. 百分数的表示法表示百分数直接将数词放在单词percent前面即可twenty percent=20%百分之二十。
