一、考点聚焦
1、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。如：第一次世界大战可以表示为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。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。
2、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：
（1）倍数用在as + 形容词 / 副词（原级）+ as结构之前。如：
They have three times as many cows as we do.
（2）倍数放在形容词或副词的比较级之前或by + 倍数用在比较级之后。如：
This rope is four times longer than that one.
They produced more products in 2001 than those in 2000 by twice.
（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。如：
This room is three times the size of that one.
The college is twice what it was 5 years age.
You can’t imagine that rats eat 40 to 50 times their weight.
3、大约数的表示方法
（1）用ten、dozen、score、hundred、thousand、million等数词的复数后加of短语来表示几十、几百、上千、成千上万等大约数概念。如：
The little boy buys dozens of pencils every term.
Thousands of people died in the earthquake.
Every year tens of thousands of people go to work in Guangdong Province.
（2）用、less than、under、below、almost、nearly、up to 等来表示小于或接近某数目。如：
He is good at English, so he can finish the paper in less than two hours.
（3）用more than、over、above、beyond、or more等来表示超过或多于某个数目。如：
Peking University has a history of more than 100 years.
（4）用or、or so、about、around、some、more or less等表示在某一数目左右。如：
About 50 people were present at that time.
（5）用to、from … to…、between … and表示介于两数词。如：
His salary rises from 20 dollars a week to 35 dollars a week.
（6）注意事项：dozen、score、hundred、thousand、million作数词表示确切数量时，不用复数。如：three score, five dozen, seven million等。
4、分数的表达方式
（1）分子用基数词，分母用序数词，分子大于1时，分母用复数。如：one-third三分之一，three-sevenths七分之三。
（2）分子与分母之间加in, 分子在前，分母在后，分子分母都用基数词。如：one in ten 十分之一，five in eight八分之五。
（3）分子与分母之间加out of , 分子在前，分母在后，分子分母都用基数词。如：one out of ten十分之一，five out of eight八分之五。
5、百分数的表示法
（1）表示百分数直接将数词放在单词percent前面即可，如：twenty percent百分之二十。
（2）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 + 冠词 / 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，如：
Two-thirds of the money was spent on food.
About seventy percent of the earth surface is covered by water.
6、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，如：9.65表示为nine point six five。218.39表示为two hundred and eighteen point three nine。
二、精典名题导解
选择填空
1. ____________ people in the world are sending information by E-mail every day.(2001年上海春季高考卷)
A.Several million B.Many millions
C.Several millions D.Many million
解析：答案为A。本题考查的是million表示确切数量的用法。million前需用数表确切数量，而不用many这类词，但可说many millions of（上百万的），故本题中用Several million。
2. The number of people invited __________ fifty, but a number of them __________ absent for different reasons.(NMET 96)
A.were ; was B.was ; was C.was ; were D.were ; were
解析：答案为C。本题考查的是the number of + 名词与a number of + 名词作主语时谓语的单复数问题。the number of是“……的数目”，作主语时谓语动词用单数，而a number of 后接可数名词的复数形式，作主语时谓语动词用复数形式，故此题最佳选项为C。
3. Shortly after the accident, two ___________ police were sent to the sport to keep order .(NMET 92)
A.dozens of B.dozens C.dozen D.dozen of
解析：答案为C。此题考查的是数词dozen表示确切数量时的用法，dozen表示确切数量时用其单数形式，当dozens的复数后接of时则表示不确切数量，本题答案为C。
