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.
Decide the points of time you want to look at – for example, now, ten years ago and ten years from now.
Research the population of your place in those years. Write your notes carefully.
Work in groups. Prepare to make your graph.
Decide how you want to make your graph.
Draw it and color it. You can also make it on the computer.
Label it clearly.
Make your graph and present your graph to the class.
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. The graph shows the population increased by more than one hundred percent from two and a half million to
Possible answer
five million in one hundred years. 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.
拓展提升
一、数字的用法。
(一)基数词的表示方法：
1、1~12 的基数词：
one，two，three，four，five，six，seven，eight，nine，ten，eleven，twelve
2、13～19的基数词，在个位数上加后缀-teen构成，并有两个重音。如：
thirteen，fourteen，fifteen，sixteen，seventeen，eighteen，nineteen
3、20～90等十位数由2~9 加后缀-ty构成。如：
twenty，thirty，forty，fifty，sixty，seventy，eighty，ninety
4、21~29由十位数20加个位数1~9 构成，十位和个位之间加连字符号“-”，其他十位数以此类推。如：
21 twenty-one，44 forty-four，98 ninety-eight
5、多位数的读法：
①从后向前数，每三位数加一个“，”；第一个“，”号前为thousand (千)，第二个“，”号前为million(百万)……，然后再逐段表达。
②三位数数词要在百位和十位(若无十位则和个位)之间加and。
如：
45，632，798
读作 —— forty-five million，six hundred and thirty-two thousand，seven hundred and ninety-eight
(二)序数词的表示方法：
序数词 = 基数词+th，但以下几个特殊：
one—first two—second
three—third five—fifth eight—eighth
nine—ninth twelve—twelfth
twenty—twentieth
a hundred—a hundredth
(三)分子用基数词表示，分母用序数词表示，分子为2 以上时，分母(序数词)应变为复数。
三分之一one third/a third
五分之三three fifths
由“分数(或百分数)+of+名词”构成的名词词组作主语时，谓语动词的单复数由of 后面的名词来决定，名词为可数名词复数,
则谓语动词用复数；名词为不可数名词，谓语动词用单数。如：
A third of the land is covered by forests.
三分之一的陆地被森林覆盖着。
Two thirds of the workers are working hard.
三分之二的工人正认真地工作。
