模块八:数词

(一)概说:

英语的数词可分为基数词和序数词两大类。基数词表示的是人或事物的个数,而序数词表示的是这些数目的顺序。

1

2

(二)数词的某些用法:

1、表示计量:表示事物的计量,即事物的长度、宽度、深度和高度,应采用基数词。

如:It is 50 metres/kilometers/miles long (wide, deep, high).它有50米/千米/英里长(宽、深、高)。

2、表示编号:编号的数字如果过小,可用序数词或基数词表示;如果数字较大,通常

用基数词表示。

如:The tenth lesson=Lesson Ten 第10课

Room 405 第405号房

Page 215 第215页

No.14 Middle School 第14中学

Telephone NO.5855806 电话:5855806

【重点】

3、表示不确切的数字:基数词后面直接加上复数名词表示精确的数字,而基数词复数形式加上“of” 表示不确切的数字。

如:five hundred students 500名学生

two thousand people 2000人

five dozen pencils 5打铅笔

hundreds of students 几百名学生

millions of workers 成千上万的工人

scores of chairs 几十张椅子

4、表示年龄和岁数

1)表示年龄的主要句式如下:

He is a boy of 10 yeas old. 他是个10岁的男孩子。

He is 10 yeas old. 他10 岁。

At the age of ten, he began to learn English. 他10岁开始学英语。

He is 10(years of age). 他10 岁。

He is a ten-year-old boy. 他是个10岁的男孩子。

2) 介词in+ one’s twenties (thirties…) 表示“在某人20多岁(30多岁……)”。

如:My father is in his fifties. 我爸爸50多岁。

When he was in his forties, he began to learn English. 当他40多岁时,他开始学

英语。

【难点】

5、表示年代:表示什么世纪,什么年代时,通常在数词后加s或’s,并在年代前加定

冠词the ,如1980’s

(20世纪80年代),读作:nineteen eighties.

如:His grandfather died in the 1970’s。他爷爷死于20世纪70年代。

【重点】

6、表示分数:分数的表达方式是:分子用基数词,分母用叙述词。分子是one时,分

母不必加s; 分

子大于one时,分母要加s.

如:a(=one) third 三分之一one fifth 五分之一

two thirds 三分之二three fourths 四分之三

Two thirds of the trees were cut down the years ago.10年前三分之二的树木被砍伐

了。

7、表示百分数:百分数的表达方式是:基数词+ percent(单数形式)+of+名词。

如:Thirty percent of the students in my class are from cities. 我班30%的学生来自城市。
