阅读短文,然后完成短文后的表格,每空一词。 From 8:30 pm to 9:30pm on Saturday, March 23 rd , 2013, 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 did you do for Earth Hour this year? Let’s share the Earth Hour stories. Emma 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 that she could enjoy this relaxing moment. Albert works as a waiter in a restaurant. Their restaurant was still open even for Earth Hour as they got lots of reservations(预定) that night. So they spent the hour working by candlelight. And guess what? Their customers loved that and promised to come for next Earth Hour. Brandon turned off the main power to his 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 light bulb! Mary invited her friends who know and support Earth Hour activities. They actually had a candlelight and they talked about the old happy days that they spent together in college.
