英語話題復習—Environmental Protection環境保護
一、整體設計思路及指導依據：
教師在進行初三總復習階段的話題教學時，要求學生把同一話題下的詞匯和功能句分類歸檔，形成網絡，以便于為下一步的書面表達做準備。所以在設計本課時根據《英語新課程標準》，本人主要運用任務型教學法及情景交際法，并采用多媒體課件進行教學。按照任務型教學的基本理念，課堂任務的設計選擇貼近學生實際生活的內容，提供符合真實生活的學習情景，通過自主、合作、探究提高學生的英語學習興趣，培養語言的綜合運用能力。

Step 6 Read and answer
① Every day, lots of plastic gets thrown away and ends up in places like the ocean, rivers, and on land. This is bad for natural ecosystems, wildlife, and even human health. ② The reason we have so much plastic pollution is that we use a lot of plastic items like bags, bottles, and straws. Because plastic does not break down（分解）easily, it stays around for a very long time. ③Everyone can help solve this problem. People are supposed to use less plastic by carrying a reusable water bottle, using cloth bags for shopping, and choosing products with less packaging（包裝）. When we do use plastic, we should recycle it, so it can be made into something new. ④The government is helping by making rules about plastic use. Some places have laws that say you can’t use certain plastic things, like straws or bags. It also encourages scientists to develop more materials that are less harmful to the environment. ⑤ Social groups are working hard too. They tell people about the problem and how to use less plastic. They call on people to clean up plastic from beaches and other places. Sometimes, they even pressure corporations(企業) to think up more environmentally-friendly ways. ⑥Plastic pollution is a serious problem that needs efforts from individuals, governments, and social groups. If we all work together, we can make less plastic pollution and save our planet.
