From 8:30pm to 9:30pm on Saturday,March 26th,2011,a great number of people around the world turned off the lights for Earth Hour.It is a bit like an environmental New Year,providing a chance to help care for our earth and make people around the world learn how important it is to do that. What can do during this hour?We can do lots of run things in the dark,such as planning a candlelight dinner for our family or a group of friends,telling stories and singing songs with the kids and neighbors. What did you do for Earth Hour this year?Let's share the Earth Hour stories. |
Emma I was on one of the mountains near the city and took photos of my city.It was great to watch the stars and the moon after a busy day so that I could enjoy this relaxing moment. |
Albert I work as a waiter in a restaurant.Our restaurant was still open even for Earth Hour as we got lots of reservations (預(yù)定) that night.So we spent the hour working by candlelight.And guess what?Our customers loved that and promised to come for next Earth Hour. |
Brandon I turned off the main power to my house and went for a walk for Earth Hour.It was a little strange to walk in the dark,but it was only for one hour.Just think of what it must have been like before the invention of the light bulb! |
