The first Earth Hour was held in 1977 in Sydney, where more than 2.2 million people switched off their lights.Today, more and more cities are taking part in the event, such as Beijing, London, Rome and New York, and landmarks like the Empire State Building and the Golden Gate Bridge will go dark.Module taskDiscussing what you can do about pollution10. Work in groups. Decide what kind of
pollution you want to talk about.● Choose a subject that you care about the most. It could be water pollution, air pollution, etc.
● Find out more information about your subject. Look it up on a website or in a book.11. Discuss your subject.● Take turns to say what you think about the problem and what can be done.
● Listen to what others say. If you agree with what they have said, say “I agree”, “That’s
true” or “That’s a good point”; if you do not agree with what someone says, say “I’m
sorry, but I don’t agree. I think that…”12. Present your group’s ideas to the whole class. Yes, I agree with you that air pollution is one of the most serious problems. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.Possible answer Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. At the same time, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment. However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed
seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution. Grammar1.合成词构词法英语中构成新词最基本的方法有三种：合成法，缩略法和词缀法。合成词构词法就是将两个独立的单词和在一起构成一个新的单词。常见的方法有：(1). 合成名词homework(家庭作业) home+work---space + ship---spaceship(宇宙飞船)after + noon---afternoon(下午)(2). 合成动词ill + treat---ill-treat(虐待)sight + see---sight-see(观光)(3). 合成形容词hard + working---hard-working(勤奋的)well + known---well-known(著名的)world + famous---world-famous(世界闻名的)(4). 合成副词down + stair---downstairs(在楼下)up + stairs---upstairs(在楼上)(5). 合成代词some +body---somebody(某人)any +one---anyone(任何人)(6). 合成介词with +in---within(在…之内)in +to---into(到…)在一个单词前或后加上一个词缀，就可以构成一个新词。 根据词缀的位置，分为前缀和后缀两种。掌握一些常见的词缀，对单词的记忆和理解有很大的帮助。比如：我们学会care, 就能掌握careful, careless, carefully, carelessly。下面我们来学习几个常见的前、后缀：2. 前缀，后缀构词法前缀：1. 常见名词后缀后缀：(1). –an: American (美国人),
