It’s important to learn about how to protect our environment. But do you know how to do it? The school has successfully held a discussion（讨论）. Here are five of the speeches.

Zhang Ming: Do you know what one-off chopsticks （一次性筷子）are made of? Yes, the wood. We should reduce waste. We should use things wisely. As everyone knows, a large number of trees are being cut down to make one-off chopsticks. If everyone uses one-off chopsticks, we would not have any trees left. Stop using one-off chopsticks.

Wang Dong: We should always think of reusing the used things before throwing them away. At school, when our reference（参考） books are used, we could give them to the younger boys or girls. Give your clothes you don’t wear or the ones which are too small to the poor. In a family, you may pass on such clothes to your younger brothers or sisters.

Liu Hang: Don’t throw away your bottles, cans and paper which you have used. They can easily be recycled. By doing so, we can save lots of time and money. For example, drink cans are sent to a factory, where they are smashed （使破碎）flat and melted and the metals are made into new drink cans.

Li Lei: When you buy a box of apples, there may be a few rotten （腐烂的）ones, you have two choices: one is to throw the whole apples away, the other is to cut off the rotten parts and eat the good parts.

Chen Hong: If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after doing some repair. 

     It is true that there are some “throw-away” places. But you see, if everyone tries his best to protect the environment and do as what the students say above, our world will become more and more beautiful.
