Unit 1 Will people have robots? 读写综合 广东省教育厅教研室 阅读下面有关环保的短文，并归纳5R的要点。 It's important to learn about protecting our environment. Here is a 5R rule for us: 1. Reduce If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If people uses paper carelessly and throws it away, soon we will not have any trees left. Other tings are also being wasted, and people don't know what to do with waste in big cities. So it is necessary to reduce waste. 2. Reuse You should always think of reusing usable things before throwing them out. Give the clothes you do not use or the ones which are too small to the poor. Within a family, you can pass on such clothes to younger brothers or sisters. 3. Recycle Bottle, cans and paper can easily be recycled. By doing this we save lots of time and money. For example, coke cans can be sent to a factory, where they are smashed flat and melted and the metal can be made for new coke cans. 4. Recover When you buy a box of apples, there may be a few rotten apples. So you have two choices: one is to throw those apples away, or another is to cut off the rotten parts and use the good parts. In this way, you recover the eatable parts of the fruit. 5. Repair If one of the legs of your table is broken, you should repair it instead of throwing it away. However, if you want to change your furniture, it is better to sell old things or give them to other people who can use them after doing some repairs. It is true that North America is a "throw-away" society, but the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
