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.

Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone.

And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it.

We believe, however, that some two thousand million years ago, another star wandering(漫游) through space, happened to come near our sun just as the sun and the moon raised its tides(潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal(潮汐的) wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space.

These small pieces have been going round the sun ever since. They are the planets.
