B.   A Week Without Plastic Last year, our school organised a "Plastic-Free Week" to raise awareness about plastic pollution. Every student was asked to avoid using any single-use plastic for seven days. I thought it would be easy, but I was wrong. On the first day, I realised that almost everything I used had plastic. My toothbrush, my water bottle, my snack wrappers—all plastic. I had to find alternatives quickly. I used a bamboo toothbrush, carried a metal bottle, and brought my own cloth bag for shopping. The hardest part was lunchtime. My sandwich was usually wrapped in plastic, but I started using a reusable container. By the third day, I got used to it. I even made my own juice instead of buying bottled drinks. My classmates also shared their tips. Some used glass jars, others used beeswax wraps. We all learned a lot. At the end of the week, we collected all the plastic we had avoided. It filled a huge bin! It made me realise how much plastic we waste every day. Now I try to keep these habits. It's not always convenient, but it's worth it. Every small change helps the planet. ( )6. What was the purpose of the "Plastic-Free Week"? A. To save money. B.

It was boring and useless. D. It was only for young children. C.   Should We Ban Plastic Packaging? Plastic packaging is everywhere. It wraps our food, drinks, and many other products. While it keeps things fresh and safe, it also creates a huge amount of waste. Many people argue that we should ban plastic packaging entirely. Others believe that a complete ban is unrealistic and that we should focus on better recycling. Supporters of a ban say that plastic packaging is the main source of ocean pollution. They point out that most plastic packaging is used once and then thrown away. It takes hundreds of years to break down, and during that time it harms wildlife. They believe that banning packaging would force companies to use biodegradable materials. However, opponents argue that plastic packaging is essential for preserving food and preventing waste. Without it, food would spoil faster, leading to even more waste. They also note that plastic is lightweight and cheap, which reduces transport costs and carbon emissions. They suggest that we should improve recycling systems instead of banning plastic. In my view, we don't need a total ban. Instead, we should reduce unnecessary packaging, use more recyclable materials, and encourage consumers to choose eco-friendly options. A balanced approach is the best way forward. ( )11. What is the main topic of the passage? A. The history of plastic packaging. B. Whether plastic packaging should be banned. C. The benefits of plastic packaging. D. How to make biodegradable materials. ( )12. Why do supporters of a ban think plastic packaging is harmful? A. It is too expensive. B. It causes ocean pollution and harms wildlife. C. It is not strong enough. D. It makes food taste bad. ( )13. According to opponents, what is one advantage of plastic packaging? A. It breaks down quickly. B. It helps preserve food and reduce waste. C. It is made from plants. D. It is cheaper than paper. ( )14. What does the author suggest as the best solution? A. A total ban on plastic packaging. B. Using more plastic packaging. C. A balanced approach with reduction and recycling. D. Ignoring the problem. ( )15. What is the author's attitude towards a total ban? A. Strongly supportive. B. Strongly opposed. C. Neutral but leaning towards a balanced approach. D. Unclear. 八、完形填空（阅读下面的短文，从每题所给的A、B、C、D四个选项中选出最佳选项） Plastic waste is one of the biggest threats to our oceans.
