But it takes hundreds of years to break down, causing serious pollution. Now, scientists have invented a new eco-friendly packaging material: mycelium packaging. Mycelium is the root structure of fungi (真菌). To make the packaging, scientists mix mycelium with agricultural waste like corn stalks. Then they put the mixture into molds (模具) of different shapes. After 5-7 days, the mycelium grows into a solid, lightweight material. Finally, they bake it to stop the growth. The new packaging is biodegradable—it can be broken down by nature in just 2 weeks. It’s also harmless to humans and animals. Unlike plastic, it doesn’t produce toxic smoke when burned. What’s more, it’s reusable: you can bury it in the soil as fertilizer after use. Many companies have started using mycelium packaging. A fruit company in Zhejiang uses it to pack apples, reducing plastic waste by 80%. “It’s a win-win for both business and the environment,” said the company manager. Of course, there are still challenges. The production cost is higher than plastic, and the material is not waterproof enough. But scientists are working to solve these problems. They believe mycelium packaging will become a mainstream choice in the future. 1. What is mycelium packaging made of?（不超过10个词） 2. How long does it take for mycelium packaging to break down?（不超过5个词） 3. What are the advantages of mycelium packaging?（列出两点，不超过20个词） 4. What challenge does mycelium packaging face?（不超过10个词） 5. What does the underlined word “biodegradable” mean in Chinese?（不超过5个词） 五、书面表达 假设你是李华，你校英语社团正在举办“Green Invention, Better Life”主题征文活动。请你写一篇80-100词的短文，介绍你的一项绿色小发明（如旧物改造的花盆、废纸做的笔记本等）。 要求： 1. 介绍发明的名称、制作材料（旧物）； 2. 说明发明的用途及环保意义； 3. 用到至少4个本单元所学的构词法词汇（如reusable, eco-friendly, biodegradable等）； 4. 开头已给出，不计入总词数。 My Green Invention I’m Li Hua.
