Plastic Pollution Plastic pollution is one of the biggest environmental problems today. Many people use plastic bags to carry their things and then throw them away. These bags end up in rivers and oceans, harming wildlife. Perhaps we should rethink about this and find a better way to use them. One way is to reuse them. After we bring our things home in a plastic bag, we can save it and use it again for something else. This is a great way to reduce the number of new plastic bags. By reusing plastic bags, we can cut down pollution and recreate a greener world. Many communities have renewed calls for reducing plastic use. Everyone can play a part in protecting the environment.

The Power of "Re-" The prefix "re-" means "again" or "back". It can be added to many words to create new meanings. For example, "use" becomes "reuse", which means to use again. "Cycle" becomes "recycle", which means to use materials again. "Build" becomes "rebuild", which means to build again after damage. "Think" becomes "rethink", which means to think about something again. These words are very useful when we talk about environmental protection. We need to rethink our habits, reuse things we have, recycle waste materials, and rebuild a better world. By doing so, we can reduce waste and protect our planet. The prefix "re-" reminds us that we can always try again and make things better. It gives us hope and encourages us to take action. ( )6. What does the prefix "re-" mean? A. Before. B. After. C. Again or back. D. Opposite. ( )7. What does "recycle" mean? A. To use again. B. To use materials again. C. To think again. D. To build again. ( )8. What does "rethink" mean? A. To use again. B.

When we use materials again. D. When we reduce waste. ( )10. What should we do to protect our planet according to the passage? A. Rethink, reuse, recycle and rebuild. B. Only recycle. C. Only reuse. D. Only think. C. Waste Sorting Experience Li Wei has kept sorting the waste at home for three years. He started after he attended a speech about environmental protection.

This creates a lot of waste. One good way to solve this problem is to reuse plastic bags. After we bring things home in a plastic bag, we can save it and use it for something else. For example, we can use it as a waste bag. By doing this, we can reduce the number of new plastic bags we use. Reusing plastic bags is a small action, but it can make a big difference. We should all rethink our habits and try to be more environmentally friendly. Part A: 判断正误（正确写 T，错误写 F） ( )1. Plastic bags are a small problem for our environment. ( )2.
