Computers are useful machines．They can help people a lot in their daily life ． For example，they can help people to save much time to do much work，and they can help people to work out many problems easily．Our country asks everyone to learn to use computers before the twenty-first century，except the old people．

    Today more and more families own computers ． Parents buy computers for their children．They hope computers can help them improve their studies in school．Yet，many of their children use computers to play games，to watch videos or to chat．Computers can not help children to study but make them fall behind．So computers are locked in boxes by parents．

    In some other countries，even some scientists also hate computers．They say computers let millions of people lose their jobs or bring them a lot of trouble．Will computers really bring trouble to people or can they bring people happiness? It will be decided by today's students themselves!

    When you go for a run outside, chances are that you'll find litter (垃圾) all around you. Do you just go past it, or do you stop and pick it up? If you choose the second, you're part of the latest popular sport in the West: plogging.

    The word "plogging" puts the Swedish phrase "plocka upp" (pick up) and the English word "jogging" (running slowly) together.

    What a plogger needs is a rubbish bag and a pair of gloves (手套)to protect your hands. While collecting rubbish, ploggers learn to classify (分类) and deal with it correctly, too.

    ①Plogging seems simple but it does a lot of good to both the environment'(环境) and your health. It can not only make the world greener, but also get you exercise, for example, a 30-minute plogging burns around 288 calories (卡路里),compared to 235 calories burned from just jogging.

    So next time you go out jogging, why not carry a rubbish bag and collect some litter along the way?②你的身体和环境会感谢你。
