Earth Hour
Earth hour started in Sydney at 7:30 pm on March 31,2007. The activity aims to save energy and improve climate. This year, more and more people all over the world took part in it on March 26. Some people had dinner with their family in the candlelight or chatted with their friends. At that time, my classmates and I were holding a party in the park, singing and dancing. Lots of people were walking in the park. And this year, Earth Hour not only asks people to turn off lights, but also calls on us to protect the environment in our daily life. We can do a lot of things. For example, we can use paper both sides. We should ride bikes or walk to school. What’s more, we’d better take our own shopping bags while shopping. Let’s do something now to help save our planet.解析:
