Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圆木)，and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.

The first Earth Hour was held in 2007 in Sydney, Australia when 2.2 million individuals(个体) and more than two thousand businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had grown into a global event with more than 50 million people across 35 countries and territories（行政区）participating(参加). Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent(紧急) by the hour. In March 2009, millions of people took part in the third Earth Hour. Over 4000 cities in 88 countries and territories have promised their official support for the event. On Saturday 27 March, Earth Hour 2010 became the biggest Earth Hour. A record said 128 countries and territories joined the global display of climate action.
The event is organized by the World Wide Fund for Nature, also known as the WWF. The organizers say climate change is one of the greatest threats(威胁) facing wildlife and nature. They also say when it comes to save energy and money, big changes start with small steps like turning out the lights. Now people are all joining together in a global effort to show that it’s possible to work on global warming. Earth Hour has brought about some new changes to our lives. People join in activities such as candle-lit dinners and star-gazing parties as a response to the call for "going dark".

This year , Earth Hour is asking people to take the next step and go beyond one hour. So if you haven’t done so, next year, late half past eight to half past nine, let us turn off the lights for one hour for the environment! Earth Hour is a call to stand up, to take responsibility(责任) and to get involved(与……有关) in working towards a better future. Earth Hour is a message of hope and a message of action. Everyone can make a difference.
