    How green are you? Do you care about protecting the environment and saving energy? 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 produces if possible, and try not to buy too many things form abroad. It may cost a lot of money to bring them to us.
    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.
    小题1:Why is it better to choose local products if possible?
    A．Things from abroad do harm to our environment
    B．Local products are much cheaper
    C．To choose local products means that we love our country
    D．Things from abroad aren’t necessary
    小题2:According to the passage, when we find our clothes are out of fashion, what should we do?
    A．Throw them away
    B．If they are still suitable, keep them
    C．Clean the floor with them
    D．Give them to others and buy new ones
    小题3:What is the helpful activity in our daily life?
    A．To shop with plastic bags
    B．To use paper cups
    C．To collect old newspapers
    D．To burn fallen leaves
    小题4:According to the passage, which of the following is RIGHT?
    A．We should learn to grow vegetables
    B．People mustn’t produce waste any more
    C．Children are too young to do anything to save energy.
    D．The simplest everyday activities are important to protect our world.
    小题5:Which of the following is WRONG according to this passage?
    A．Always buy new things and throw away old ones
    B．Use china cups instead of paper cups
    C．Recycle something that can be recycled
    D．Think first when we want to buy something

    Many places in the world need more fresh water．Every country is trying to find ways to turn salt water into fresh water．

    Why aren’t there many factories like the Symi factory?

    In some places, the sun is not hot enough, or it does not shine every day．

    In such places, other ways of heating sea water can be used．These ways cost more money, but they work faster than the sun．By boiling sea water with high heat, a lot of fresh water can be made quickly．

    But heating is not the only way to get fresh water from salt water．Other ways are tried．

    One way is freezing (冷冻)．The fresh part of salt water freezes first．To get fresh water, the bits of ice are taken out．

    Which way is the best? The one that gives the most water for the least money．There may be a different way for each place．

    Symi’s way seems very good for small, hot places．It does not make very much water at a time．But the factory is easy to build and costs little．

    That is why people in many dry places talk about Symi．
