C 拓展思考（示例） Part 1 In my neighborhood, there is too much noise from cars and construction. The noise continues even at night. This makes it hard for me to sleep and study. It also makes my grandparents feel stressed. I think we should build more noise barriers and ask drivers not to honk loudly. If everyone tries a little, the problem can become better. Part 2 First, we should turn off lights when we leave a room because it saves energy. Second, we should use reusable bags instead of plastic bags because plastic causes land and water pollution. Third, we should plant trees because trees clean the air and give animals homes. These actions are small but every action helps. Part 3 I would write a song called “Clean Our World”. I would say: “Don’t throw rubbish on the ground, keep our planet safe and sound.” I think this theme is important because pollution is harming animals, people, and the earth. If everyone sings and remembers, they might act better. Our future depends on what we do today. So we must save the planet now. 1 学科网（北京）股份有限公司 $
