Last month, my class started an environmental project. Our goal was to learn how to live a “green life” and reduce waste. First, we did a survey about how we waste things at home. We found that most families use too many plastic bags and throw away paper that can be 16. So we decided to take action. We made 17 to tell students and their parents about recycling. We displayed them in the school hall and neighborhood. The posters said, “Recycle paper and plastic—save our resources!” We also gave a speech in class about the importance of saving power. We told everyone to 18 lights and TVs when they are not in use. Then, we started a “no plastic” day at school. We asked students to bring cloth bags instead of plastic ones. The school also 19 the use of plastic bottles—students had to bring their own water bottles. At first, some students thought it was inconvenient, but soon they got used to it. We also helped clean up the park near our school. We 20 holes to plant small trees and picked up rubbish. We separated the rubbish into different bins—paper, plastic, and food waste. A park worker told us that our small actions would 21 to the park’s environment. After a month, we saw a big difference. Less plastic was used at school, and more students started recycling.

Here are simple ways to do it at home: 1. Save Power - Turn off lights, TVs, and computers when you leave a room. Even small lights use power if they are left on. - Use energy-saving bulbs (灯泡). They use less power and last longer than regular bulbs. - Don’t leave the fridge door open for a long time. It makes the fridge work harder and uses more power. 2. Reduce Plastic Waste - Use cloth bags for shopping instead of plastic bags. Keep a cloth bag in your bag or car so you don’t forget. - Reuse plastic bottles and containers. Wash them and use them to store food or water. - Avoid buying food with too much plastic packaging (包装). Choose products with paper or glass packaging instead. 3. Recycle and Reuse - Separate your rubbish into different bins: paper, plastic, glass, and food waste. Many cities have recycling programs that collect these bins. - Reuse old clothes. You can turn them into rags (抹布) for cleaning or give them to charity. - Compost (堆肥) food waste. It turns into fertilizer that you can use for plants in your garden. 4. Save Water - Turn off the tap when you brush your teeth. You can save up to 5 liters of water every minute. - Fix leaky taps (漏水的水龙头) quickly. A leaky tap can waste 20 liters of water a day. Living a green life is easy and doesn’t cost much. Small changes can make a big difference to the environment. 26. What is a “green life” according to the passage? A. Living in a house with many plants. B. Protecting the environment by reducing waste and using resources wisely. C. Eating only green vegetables. D. Wearing green clothes every day. 27. How can we save power at home? A. Leave lights on when leaving a room. B. Use regular bulbs instead of energy-saving ones. C. Turn off the fridge door quickly. D. Keep the TV on all day. 28. What can we do to reduce plastic waste? A. Use cloth bags for shopping. B. Throw away plastic bottles after use. C. Buy food with lots of plastic packaging. D. Use plastic bags for storing food. 29. How much water can a leaky tap waste a day? A. 5 liters. B. 10 liters. C. 15 liters. D. 20 liters. 30. What is the main idea of the passage? A. How to grow plants at home. B. Simple ways to live a green life at home. C. How to recycle plastic bottles. D. Why we need to save water. （B） The Problem of Plastic Pollution Plastic pollution is one of the biggest environmental problems today. Plastic is cheap and useful, but it is also harmful to the planet. Most plastic doesn’t break down easily. It can stay in the environment for hundreds of years. Plastic waste pollutes the ocean—millions of sea animals like turtles and fish die every year because they eat plastic or get stuck in it. Plastic also pollutes soil—when it breaks into small pieces, it harms plants and animals that live in the soil. People use a lot of single-use plastic (一次性塑料), like plastic bags, bottles, and straws (吸管). These items are used for a short time but stay in the environment for a long time. For example, a plastic bag is used for about 15 minutes, but it can take over 200 years to break down. Many countries are taking action to stop plastic pollution. Some countries have banned (禁止) single-use plastic bags. Others have started recycling programs to collect and reuse plastic. Some cities also fine people who throw plastic rubbish in public places. We can also help stop plastic pollution. Here are some steps: - Bring your own cloth bag when shopping. - Use a reusable water bottle instead of plastic ones. - Say “no” to plastic straws when drinking. - Recycle plastic waste correctly. Plastic pollution is a serious problem, but we can solve it if we work together. Every small action counts. 31. Why is plastic harmful to the planet? A. It is expensive. B. It doesn’t break down easily and pollutes the environment. C. It is not useful. D. It can’t be recycled. 32. How long can a plastic bag take to break down? A. About 15 minutes. B. About 100 years. C.
