【简答题】
Why do we like drinking water from plastic bottles? Some people think it is healthy and clean. Others drink bottled water because it’s easy — you can carry it around with you. In hot countries, like Greece, we often buy bottles of cold water in the summer. However, making lots of plastic is not a good idea for many reasons. First of all, we need a lot of oil for plastic products. We usually use oil as a source(资源) of energy. If we reduced the number of bottles we made, we wouldn’t need so much oil. Plastic bottles also pollute the environment. If we recycled all our plastic bottles, we wouldn’t need so much space for rubbish dumps. But in Greece, we don’t recycle much of the plastic we use. In 2006, Greeks recycled only about 10% of plastic waste. The rest became rubbish on land and in rivers and sees. So next time you want to throw away a plastic bottle in the litter bin, stop and think. If you recycled it, you would help the environment. But what can you do when there isn’t a recycling bin near you? Well, there are loes of useful ways that you can use your bottles again. For example, an empty bottle makes a great piggy bank for your pocket money, and if you cut a bottle in half, you will have a plant pot. Go green!
