[2025 唐山一模改编]Plastic is a man-made material made from oil. It's long-lasting and found almost everywhere. From the paint on the walls to the keyboard we use, plastic is a big part of our everyday lives. It is truly a wonder material that has made lives easier.
However, plastic also causes some problems. First, plastic is made from fossil fuels (化石燃料), and its production gives out greenhouse gases. These gases keep heat in the air, causing the Earth's temperature to rise. Another problem is that plastic takes hundreds of years to break down. Around 400 million tons of plastic waste are produced worldwide each year. Plastic bags create rubbish that is dangerous to wildlife, as animals sometimes mistake plastic for food. Every year, thousands of animals die because of this.
So, how can we solve the problem? Many organizations are working to clean up plastic waste, especially in oceans and rivers where plastic pollution is the worst. But everyone can also do their part. For example, we can use reusable bags when shopping and avoid ordering takeout with lots of plastic materials. We can refill our water bottles rather than buy new ones. We can also keep our phones longer instead of always buying new ones. Remember, even small actions can make a big difference.
Let's make more changes to reduce plastic waste. If everyone helps, we can save our planet.
1. What is plastic made from?
A. Cotton. B. Wood. C. Oil. D. Waste.
2. What problem does plastic bring?

B. It does harm to some animals.
C. It makes the air become cold.
D. It causes people to waste money.
3. What can we do to reduce plastic pollution?
A. Avoid unhealthy food production.
B. Change new phones every year.
C. Set up animal protection organizations.
D. Take reusable bags when shopping.
4. How does the writer feel about reducing plastic waste?
A. Excited. B. Confident.
C. Doubtful. D. Disappointed.
