外研社英语课文：Module 6 Save our world

中考网

　　Hey, you guys! Guess what! We've just got an email from a reader of our New Standard!
        　　Great! What does it say?
        　　It's from Zhao Ming. He says,"I saw your enjoyable online magazine while I was doing my homework on favourite books."
        　　He read Mr Jackson's article!
        　　He says,"When are you going to write about environmental education? I'm at a green school in Dalian…"
        　　What's a green school?
        　　"…and everyone agrees we must be careful about the environment. In fact, there are thousands of green schools in China. It's wasteful to throw away glass, paper and metal, so every class collects reusable waste, sells it for recycling…"
        　　Nice idea!
        　　"…and raises money to help students in poor areas. But it's not just at school, it's also at home that we save energy and recycle…"
        　　Such as …
        　　"…such as turning lights off, so we don't waste electricity."And he finishes,"I'm hopeful that if everyone thinks about pollution and recycling, we can protect the air and the oceans, and help save our world. If we don't, the future is hopeless."
        　　Let's ask Zhao Ming to write something.
        　　How to be green
        　　How green are you ? Do you care about protecting the environment and saving evergy? Try these questions and see.
        　　Do you try to walk or ride a bike to school?
        　　Do you buy new clothes just because they are the latest fashions?
        　　Do you open a window instead of turning on air conditioning?
        　　Do you buy things produced locally instead of made abroad?
        　　Do you take your own cloth bag when shopping instead of using plastic bags.
        　　Do you sort the waste before throwing it away?
        　　We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.
        　　Remember these three words: reduce, reuse and recycle.
        　　Reduce
        　　Reduce means "use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary --- or maybe the old one will be just as good!When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
        　　Reuse
        　　Reuse means "use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china cup and a lunch box because you can use them again.
        　　Recycle
        　　Recycle means"change things into something else". Although it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials such as recycled paper, to help save trees.

        　　The Internet joins millions of computers all over the world, and today it's used by people all over the world. It was invented in the 1960s in the USA. The American government needed a network of computers for its army. Then in the 1970s scientists and businesspeople also wanted to use the Internet to send and receive messages. For some years, they weren't allowed to use the US network, and when they were allowed to, the messages were in very simple text without photos.
        　　The World Wide Web was invented by a British scientist named Tim Berners-Lee in 1989. He wanted to send documents to other scientists. So he developed the World Wide Web. This allowed him to send and receive scientific documents with text, drawings and photos (also called multimedia documents). In the 1990s, more and more people began to use the Internet and the World Wide Web.
        　　So what's the difference between the Internet and the World Wide Web? The Internet is the hardware. It allows us to communicate with other people. The World Wide Web is the software. It allows us to create, see and read multimedia documents.
        　　The web is made up of millions of documents called web pages. These pages are held in computers all over the world. Many people have a favourite website with a number of web pages on the same subject.
        　　Email is a way of using your computer to send and receive messages. It's cheaper and quicker to use email than send normal mail. New users call normal mail "snail mail" because it's so slow!
        　　It took 50 years for 100 million people to listen to the radio. It took 15 years for 100 million people to watch television. By the year 2000, it had taken only about three years for 100 million people to use the Internet. What will happen next on the Internet?
