seventy-five 75
ninety-six 96
2、20—90等十位数
3、百、千、万
百 hundred 100 one hundred
200 two hundred
以此类推····
千 thousand 1 000 one thousand
2 000 two thousand·········
英语里没有“万”这一单位，万也用thousand
表示。如：
10 000 ten thousand 一万
20 000 twenty thousand 两万·····
4、十万、百万
十万的说法是：100,000 a (one) hundred thousand
200,000 two hundred thousand
million 百万 a (one) million 1 000 000
two million 2 000 000
········以此类推 ······

1）101~999的三位数由“百位数＋and+两位数组成”。 如：325—three hundred and twenty-five
102 one hundred and two
635 six hundred and thirty-five
多位基数词读法
2)三位数以上的数，从个位往前数，每三位数加一个逗号，从后往前数的第一个逗号代表thousand, 第二个逗号代表million, 第三个逗号是billion，注意这几个词不能用复数形式，后也不能加and。例如：
2,648
two thousand, six hundred and forty-eight
16,250,064
sixteen million, two hundred and fifty thousand, sixty-four
确切数目与不确切数目的表达：
hundred, thousand, million, billion等前面有
基数词，表示确切数目时，用单数，后直接
接复数名词；如：
three hundred books
one hundred people
five thousand students
seven million starts
表示不确切数目时，这类词后加-s且与of连
用。如：
hundreds of people
thousands of students
millions of birds
billions of lions
注意：这类短语中，名词前如有定冠词、指
示代词或形容词性物主代词时，可加of, 但
表示的是范围。如：two hundred of the
workers工人中的二百（人）

11 Work in pairs and discuss this question.
World population and water
With more and more people in the world, more and more water is used. In fact, water use is growing more than twice as fast as the world’s population! As a result, getting good, clean water is becoming a problem in many places. A lot of water is polluted and in many areas people have to walk a long way to get clean water for daily use. More than 3.4 million people die each year from drinking and washing with polluted water. So let’s do everything we can to stop the pollution and save water.
Choose a country or town which interests you. It could be your home town.

14 Write a paragraph to describe your graph.
In the graph, we can see how the population in the town changed between 1900 and 2000. we can see the population going up the vertical line and the years going across the horizontal line.

At first it increased very slowly, but after 1945 it increased much more quickly. From 1990 to 2000, the population even increased by one million. The town itself also grew in size during this time.
