Unit 1 单元拓展阅读训练 2023—2024学年 牛津上海版（试用本） 英语九年级下册 一、阅读理解 How do you deal with plastic bags from the supermarket? Throw them away or recycle them? How about eating them? The bags are not harmful to the environment. Humans and animals can safely eat them. An Indian company EnviGreen has made a bag with natural materials. It looks and feels just like plastic, but it can be broken down(分解) easily. Ashwath Hedge who set up EnviGreen spent four years doing experiments with 12 natural materials. They included potatoes, corn, vegetable oil and bananas. He made the materials into liquid(液体) and used the liquid to make the bag. Although the EnviGreen bag is more expensive than a common plastic bag, it has many advantages. According to The Wall Street Journal, it takes 1,000 years for common plastic bags to be broken down. But an EnviGreen bag can naturally be broken down in less than 180 days. It is also broken down in less than a day in water, and in less than a minute in boiling water. Hedge was happy to show it in his interview. He put an EnviGreen bag in water and ate it with a smile. There are more than 15,000 tons of plastic waste in India every day.
