Background information
地球一小时(Earth Hour)是世界自然基金会(WWF)应对全球气候变化所提出的一项全球性节能活动,提倡于每年三月最后一个星期六的当地时间晚上20:30(2024年地球一小时时间为3月30日晚上20:30),家庭及商界用户关上不必要的电灯及耗电产品一小时,以此来表明他们对应对气候变化行动的支持。过量二氧化碳排放导致的气候变化已经极大地威胁到地球上人类的生存。所以公众只有通过改变全球民众对于二氧化碳排放的态度,才能减轻这一威胁对世界造成的影响。

Reading
节约用电的方法有很多,每年一次,人们会参加“地球一小时”活动,关灯一小时。让我们来了解一下这个活动。
What is Earth Hour
On the last Saturday night of March every year, people around the world turn their lights off for one hour. They do this because they care about climate change. They are trying to show that small changes can make a great difference to our planet.
How did it start
The World Wildlife Fund (WWF) started Earth Hour in 2007, in Sydney, Australia. More than 2.2 million homes and businesses joined in. Even the lights at the Sydney Opera House were out for an hour. This saved a lot of electricity. The same amount of electricity could power thousands of computers or television sets for an hour. When the lights were out, the stars were clearer in the sky.
  
Earth Hour
People in China liked this idea too. They started to take part in the event in 2008. Every year, many landmark buildings in Chinese cities turn off their lights for Earth Hour.

What can you do
You can take part in Earth Hour next March. Find out the date and time of the event on the Earth Hour website. When the time comes, turn off your lights and enjoy your special hour in the dark. It will be even more fun if you ask your friends, family and classmates to join as well.
“地球一小时”表明了我们对节约能源和保护地球的承诺。2023年“地球一小时”的口号是“为地球献出一小时”。
