高考 数词
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 people
two dozen of them
three 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 eighteenth
I 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 quarters
②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。
注意：分数和百分数后面不能直接接名词或代词，而用以下形式：
分数/百分数＋of +限定词+名词/代词，其谓语动词与of后的名词在人称和数上保持一致Two-thirds of the money was spent on food.
About seventy percent of the earth surface is covered by water.
3. 小数的表示法
小数的表示法，小数点前的总值发同其他数词一样，小数点用point,小数点后面的数读成个位数
9.65表示为nine point six five
218.39表示为two hundred and eighteen point three nine
注意：小数点读point，“零”读字母o的音或zero，小数点前就按基数词去读，小数点后的数字按个位基数词依次读出。
62.62读作sixty-two point six two 0.04 读作zero point zero four
五数词的其它表达式
1、序号表示法
1）单纯的序号，可在基数词前加number,简写为No.。
第一号No.1 第三中学No 3 Middle School
2）事物名词的序号表达法有什所不同：
①对于一些小序号可有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。
第一次世界大战the First World War或World War One
②对于一些大序号我们通常只用一种表达法，即名词+数词。
501号房间Room 501 538路公共汽车Bus 538
人民路153号153 Renmin Road
③可用a / the + number + 基数词+ 名词。
一辆五路公共汽车 a No.5 bus 那辆8路公共汽车the No.8 bus
2. 大约数的表示方法
1）用less than、under、below、almost、nearly、up to 等来表示小于或接近某数目。
He is good at English, so he can finish the paper in less than two hours.
2）用more than、over、above、beyond、or more等来表示超过或多于某个数目。
Peking University has a history of more than 100 years.
3）用or、or so、about、around、some、more or less等表示在某一数目左右。
About 50 people were present at that time.
4）用to、from …to…、between …and表示介于两数词。
His salary rises from 20 dollars a week to 35 dollars a week.
3. 钟点、日期、年龄的表达式
1）1）钟点两种读法：一是直接读数字，先读钟点数后读分钟数；二是用介词past表示几点过几分（分钟时间不超过半小时）或用to表示差几分就几点（分钟时间超过半小时，还差多少分钟到下一个钟点）这时先读分钟数再读钟点数。
正读法10：20：ten twenty 倒读法9：30：half past nine(九点半)
7：05：five past seven(七点过五分) 8：50：ten to nine (八点五十；差十分是九点)
表示整点8:00：eight o'clock (sharp)
2）日期
①年代用基数词，在某年要用介词in：He was born in l983.他出生于1983年。
②月份首字母要大写，在某月也用介词in，如果有年代出现，在月份名后加年代，中间用逗号：
It happened in January，2009．这事发生在2009年1月。
月日同时出现时可有两种表示法：
英国说法：顺序为先日后月：4(th)May(五月四日：the fourth of May)
美国说法：顺序为先月后日：May 4(th)(五月四日：May the fourth)
③表示在某月某日，不管用在前还是在后，都用介词on：
The meeting will be held on March 9(th)．
We'll leave for Shanghai on 8th June．
④年月日同时出现时，年代位于最后，其前加逗号：Mary was born on January 1st，1990.
⑤表示“在几十年代”用in+the+逢十的数词复数：in the 1990s／1990’s
3）年龄
①用基数词表示年龄。The baby is one year old．
②表示“在某人的几十岁”时，可用介词in+ one’s+整十位数的复数形式：
She is still in her twenties．她才二十几岁。
但表示十多岁时用：in one’s teens
表示“一个九岁的男孩”，可以有多种表达法
a boy of nine，a boy of nine years old，a boy of nine years of age，a nine-year-old boy
③用在习语中。in twos and threes三三两两地
4. 倍数的表达方式
一般情况下我们用以下三种倍数表达方式：
①A+be+倍数+as+形容词/副词（原级）+ as+B
This tree is three times as tall as that one. 这棵树是那棵的三倍高。
His father is twice as old as he. 他父亲的年纪有他两倍大。
②A+be+倍数+形容词或副词的比较级+than+B或by + 倍数用在比较级之后
The Yangtze River is almost twice longer than the Pearl River. 长江差不多比珠江长两倍。They produced more products in 2009 than those in 2008 by twice. 2009年产品是2008的两倍。
③倍数用在表示度量名词前，其基本结构为：倍数+ the + size / length / weight …+ of + 表示比较对象的名词，也可用于倍数+ what引导的从句中
This room is three times the size of that one.这房间是那房间的三倍大。
The college is twice what it was 5 years ago.这个学院是5年前的两倍。
