No-car day was first started by 35 cities in France on September 22nd, 1998. It was started to protect the environment. By now, more than 1,000 cities around the world have had a no-car day. In China, more and more people are taking part in the activity. The slogan(标语) for no-car day is, “If we drive for one less day, we can have one more nice day.” On a no-car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air. So remember: Walk, jump, ride bike or run! Use your legs! It's lots of fun! Turn off water! Do you know that some toilets could waste twenty to forty litres of water an hour? In a year, that will fill a small river!

When you sell your old products, which don't save much electricity, and buy new, greener ones, the government will give you some money back. For example, if you change your old fridge for a new, greener one that uses less electricity, you may get 300 to 800 yuan. The money makes new products cheaper for people. Since January 2025, the rules for it have been clear, so it's easy to get the money. This policy is good for everyone. For people, it saves money. For factories, it makes them want to make more green products. For the earth, reusing old products helps save resources and cut down waste. Old mobile phones and TVs can be taken apart, and their useful parts can be used again. Besides getting money back, there are more fun ways to shop now. Online and in-store sales events make shopping more interesting. Many people like to buy services, such as home cleaning, instead of just buying things. A shopper said, “This policy helps me to save much money. The new fridge also uses less electricity. It's good for my family and the earth.” With this policy, people's life is better, and our planet is greener. 1.What is the main purpose of the “trade-in for new” policy?
