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 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.12 Work in groups.

Then Present your graph to the class.Pair workBeijing is a huge city.
北京是一个大都市。
huge 在这里表示“大，巨大”。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high?
例如 a tall woman 一个高个子妇女
a tall horse 一个高大的马 Language points⑵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。 Exercises 用a, an, /, the 完成下列句子。1. ____ Knowledge is power.

Recite all the words and phrases of this unit.婴儿潮（baby boom），指的是在某一时期及特定地区，出生率大幅度提升的现象。历史上有记载的几次婴儿潮，通常是起因於有振奋人心的因素，像是农作物丰收、打赢战争及赢得体育竞赛等。但也有因为迷信的因素。在英文，形容婴儿潮时期出生的人为 baby boomer。 婴儿潮（baby boom）这个词的首次出现，主要是指美国第二次世界大战后的“4664”现象--从1946年至1964年，这18年间婴儿潮人口高达7800万人。在世界上大多数国家均有此现象。在日本，称呼此时期出生的人为“团块世代”団块の世代 。新中国成立后共出现过三次婴儿潮，值得注意的是：目前人口众多的“80后”一代也已长大，陆续成家立业。在21世纪的前15年，中国将迎来新一轮的“婴儿潮”。以此类推，每次“婴儿潮”平均都会有20-30年的周期。 撒哈拉沙漠(英文名为：Sahara Desert)世界上阳光最多的地方，也是世界上最大和自然条件最为严酷的沙漠。
撒哈拉沙漠是世界最大的沙漠，几乎占满非洲北部全部。东西约长4,800公里(3,000哩)，南北在1,300～1,900公里(800～1,200哩)之间，总面积约8,600,000平方公里(3,320,000平方哩)。撒哈拉沙漠西濒大西洋，北临阿特拉斯山脉和地中海，东为红海，南为萨赫勒一个半沙漠乾草原的过渡区。
撒哈拉沙漠是世界上除南极洲之外最大的荒漠，位于非洲北部，气候条件极其恶劣，是地球上最不适合生物生长的地方之一。阿拉伯语撒哈拉意即“大荒漠”。 1.世界最寒冷之极 南极洲的年平均气温在－28℃，大陆内部的年平均气温在－40～－60℃，
最低气温达－89.6℃
2.暴风雪最强之地 南极沿海地区的年平均风速为17～18米/秒，阵风可达40～50米/秒。最大风
速达到100米/秒，被喻为“世界的风极”，“风暴杀手”。
3.最干旱的大陆 南极大陆的年平均降水量为55毫米，随着大陆纬度的增加降水量明显减少，大陆
中部地区的年降水量仅有5毫米。在南极点附近，年降水量近于零，比非洲撒哈
拉大沙漠的降水量还稀少。所以，南极是世界上最干旱的地区。其主要原因是固
态的冰雪降落在大陆后形成巨大的冰盖，加之极端寒冷的气候和极少的日照量，
冰盖的累积量还略大于消融量，形成干燥的“白色沙漠”。
4.最荒凉孤寂的大陆 南极大陆是世界上至今唯一没有常住居民的大陆。只有一些南极考察国家的科学考察人员短期的在南极工作，每年约2000人左右。 Module?9?
