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.
Around the world
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.
12. Work in groups. Prepare to make your graph.
Module task: Making a 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.
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. 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.
1. Beijing is a huge city.
北京是一个大都市。
huge 在这里表示“大的，巨大的”。
另外表示“大的”还有“ big, tall, vast, large, great” 等。
⑴说人、动物、树木等有生命的东西，主要用tall不用huge。
例如 a tall woman 一个高个子妇女
a tall horse 一个高大的马
关于“大的”的英文表达及其辨析
⑵说一个不与地面接触的人和物的高时，要用high，而不用tall。比如人站在桌子上时，飞机飞上天时。例如：
He is high up in the tree.
他高高地爬在树上。
The plane is so high in the sky.
飞机在空中这么高。
⑶ 指建筑物、山时要tall或high都可以，不过
high的程度比tall高。
⑷ high可作副词，tall不能。
⑸ tall的反义词为short, high的反义词为low。
e.g. Our factory is a big/large one.
我们的工厂很大。
（1）在表示物体重量、人的身高大或长大了时，只能用big。
e.g. The box is too big to carry.
这个盒子太大，拿不了。
（2）在表示数量时，用large, 不用big。
e.g. A large number of people came from all parts of the country to see the exhibition.
从全国各地来了很多人观看展览。
big 和large都可表示具体事物形体或面积的大小, 往往可以互换，但big较口语化。
E.g. There have been many great presidents in American history.
美国历史上有很多伟大的总统。
在表示抽象意思时, 有也可用big, 但great更为正式。
e.g.
Great/Big changes have taken place in our country in recent years.
近几年来我们国家发生了很大变化。
great 的意思是“大、伟大的”多用于抽象意思。
在修饰具体事物时?带有一定的感彩。
vast常用来指“广袤无垠的”、“面积广阔的”。
e.g. a vast forest, a vast sea, a vast desert, vast darkness等。
huge指“巨大的”，往往指体积。
e.g. a huge stone, a huge building等。
