题型：单项选择题 阅读理解。 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 to live green life. Remember these three words: reduce, reuse and recycle. Reduce means"use less". Don't waste things. This saves money and reduces pollution and waste goinginto the environment. Before we buy something new, think if it is really necessary or maybe the old one willbe just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad. Reuse means"use again". Use things for as long as possible. When we buy things, make sure that they lasta long time. We should take care of them so that they will last, and we should repair them if we can insteadof 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 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 yourneighborhood and take part in recycling programmes. We should also buy products made from recycledmaterials, such as recycled paper, to help save trees.
