数词是表示数目多少或顺序多少的词,在英语的学习中数词的基本的用法大家了解吗?下面是我给大家带来的有关于数次的基本用法的介绍,希望能够帮助到大家。

1基数词

1. 基数词写法和读法: 345 three hundred and forty-five。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。

This took place in the 1930s. 这事发生在20世纪30年代。

4.基数词一般是单数形式,但下列情况,常用复数:

a. 与of 短语连用,表示概数,不能与具体数目连 用,如scores of people 指许多人;

b.在一些表示"一排"或"一组"的词组里;如:They arrived in twos and threes.

c. 表示"几十岁",如 in his thirties

d. 表示"年代",用 in +the +数词复数;如in the 1980s

e. 在乘法运算的一种表示法里,如:3 x 5 = 15 Three fives is (are) fifteen.

2序数词

序数词的缩写形式: first---1st second---2nd thirty-first---31st

3数词的用法

1)倍数表示法

a. 主语+谓语+倍数(或分数)+ as + adj. + as

I have three times as many as you.

b. 主语+谓语+倍数(分数)+ the size (amount,length…) of…

The earth is 49 times the size of the moon.

c. 主语+谓语+倍数(分数)+ 形容词(副词)比较级+ than…

The grain output is 8 percent higher this year than that of last year.

d. 还可以用by+倍数,表示增加多少倍

The production of grain has been increased by four times this year.

2)分数表示法

构成口诀:分子基数词,分母序数词。分子大于1,分母加-s:

1/3 one-third ; 3/37 three and three-sevenths

4常见考法

1. 序数词的不规则变法;2. 大概数的表达方法;3. 倍数的表达方法

5误区提醒

1.对基数词的形式掌握不清;2.对概数的表达词组掌握不清;3.倍数的表达行形式混淆不清。

典型例题

1.The tsunami killed ____ people in south and southeast Asia.

A.ten thousands B. ten thousands of

C. tens of thousand D. tens of thousands of

解析:错选B。当hundred, thousand, million, billon 等数量单位前有具体数字时不要用复数,表概数时其后加s且后加of。因此“几十万”的表达应为“tens of thousands of”,正确答案C。

2.At a rough estimate,Nigeriais ___Great Britain.

A. three times the size as B. the size three times of

C. three times as the size of D. three times the size of

解析:错选A。倍数的表达方法不再赘述,见上面讲解。正确答案D。

1常见考法

1.形容词的辨析;

2.复合形容词的构成;

3.形容词的句法功能;

4.多个形容词定语的排序;

5.形容词的比较等级。

形容词和副词

1.“as+形容词+(a/an)+名词+as”表示同级比较,注意中间的形容词和名词并列时各自所在的位置。

It is generally believed that teaching is as much an art as it is a science.

人们普遍认为,教学是一门科学,同时也是一门艺术。

2.“as+形容词/副词的原级+as”与“not as/so+形容词/副词的原级+as”表示同级比较,即两个或两部分人或物在性质上或程度上相同(不同)。

The work is not as/so difficult as you imagine.

这项工作不是像你想像的那么难。

3.“the+比较级+of the two +名词”表示“两者中较……的那个”。

The taller of the two boys is my brother.

两个男孩中较高的那位是我哥哥。

4.a+形容词比较级+n.……

After two years’ research,we have a far better understanding of the disease.

研究两年之后,现在我们对这种病有更好的理解。

We went to the USA in search of a better life.

为了寻找更美好的生活我们去了美国。

5.比较级的修饰语常见的有:rather,much,still,even,far,any(用于否定句或疑问句),a lot,a little,a great deal,by far,a bit 等。

The students study even harder than before.

学生们学习比以前更努力了。

目前正在建的那座桥是横跨黄河之上的桥当中最长的桥。

I’d like to buy the second most expensive camera.

我想买仅次于最贵的照相机。

(2)否定词+比较级=最高级。

There is no greater love than that of a man who lays down his life for his friends.

为朋友而放弃生命的人的爱是最伟大的爱。

—Are you satisfied with what he said at the meeting?

——你对他在会议上说的满意吗?

—No.It couldn’t have been worse.

——不,不能再差了。

7.表示倍数的句型:

(1)A is+倍数+比较级+than+B

(2)A is+倍数+as+原级+as+B

(3)A is+倍数+the+名词(size,length,height 等)+of+B

(4)A is+倍数+that+of+B

(5)A is+倍数+what 引导的名词性从句

①This building is three times higher than that one.

This building is three times as high as that one.

This building is three times the height of that one.

这个建筑物是那个建筑物的3倍高。

②The output of this year is 3 times that of 2008.

=The output of this year is 3 times what it was in 2008.

③After the new technique was introduced,the factory produced twice as many cars in 2008 as the year before.

自从新技术被引进以后,这家工厂2008年生产的小汽车是上一年的两倍。

8、形容词修饰名词,说明事物或人的性质或特征。

1)性质形容词有级的变化,可以用程度副词修饰,在句中可作定语、表语和补语。例如:hot

2)叙述形容词只能作表语,所以又称为表语形容词。这类形容词没有级的变化,也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如:afraid,

afraid,alike,alive,alone,asleep,awake, well,unwell,ill,faint等。

3)形容词作定语修饰名词时,要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时,要放在这些词之后,例如:something nice

9、以-ly结尾的形容词

1) 大部分形容词加-ly可构成副词。但 friendly,deadly,lovely,lonely,likely,lively,ugly,brotherly,仍为形容词。

2)有些以-ly 结尾既为形容词,也为副词。

daily,weekly,monthly,yearly,early

The Times is a daily paper.

The Times is published daily.

10、用形容词表示类别和整体

1) 某些形容词加上定冠词可以泛指一类人,与谓语动词的复数连接。如:the dead,the living,the rich,the poor,the blind,the hungry等。

The poor are losing hope.

2) 有关国家和民族的形容词加上定冠词指这个民族的整体,与动词的复数连用。

the British,the English,the French,the Chinese.

The English have wonderful sense of humor.

多个形容词修饰名词的顺序

11、多个形容词修饰名词时,其顺序为:

限定词+数量词(序前基后)+性状形容词+大小、长短、高低等形体+新旧+颜色+国籍+材料

those + three + beautiful + large + square+ old + brown + wood + table s

2误区提醒

1.形近、意近词的混用 2. 形容词的句法功能用错 3.复合形容词的构成不熟悉4.多个形容词作定语时排序不清 5.形容词的比较等级用错

【典型例题】:

1) One day they crossed the ____bridge behind the palace.

A. old Chinese stone B. Chinese old stone

C. old stone Chinese D. Chinese stone old

解析:错选B。 几个形容词修饰一个名词,他们的排列顺序是:年龄,形状,大小+颜色+来源+质地+用途+国家+名词。正确答案A.

2)It’s a relief for us to know that something _____ is being done to rebuild the schools destroyed in the quake.

A. competitive B. passive C. sensitive D. positive

解析:因形近形容词分辨不清而错选其他。根据题意,本句话表达“我们了解到,为了重建在地震中被破坏的学校,正在采取一些积极的措施”。空处应填“积极的”,正确答案为D。

3)--- Our women athletes achieved great success in the Vancouver Olympic Winter Games.

--- Yes. No one could have a_____ performance,I think.

A.well B. better C. best D. the best

解析:因形容词比较等级用法没掌握好而错选C. 此处应用比较级表最高级意思。正确答案为B。
