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.

Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere (大气).
The climate is changing. Many agreed that climate change may be one of the greatest threats (威胁) facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities (极端性) in weather patterns.
Is the Earth getting warmer? Yes! The Earth has warmed by about 1°F over the past 100 years. But why? Well, scientists are not exactly sure. The Earth could be getting warmer on its own, but many of the world’s leading climate scientists think that things people do are helping to make the Earth warmer.
Global Warming may be a big problem, but can you make a difference? Yes! There are several little things you can do to make a difference. Try carpooling. This will help reduce the amount of fossil fuels going into the atmosphere. Whenever you use electricity, you help put greenhouse gases into the air. Turn off lights, the television, and the computer when you are through with them. Also, planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air. Finally, don’t forget about recycling.

As many as 10 of the 17 kinds of penguins（企鹅）may be in danger of disappearing. The number of penguins have decreased(减少) by 30% since 1987.
　　Penguins are black and white birds that live in the southern part of the world. They are common in South America，New Zealand，Australia and South Africa. Many live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly，but they are fine swimmers. Penguins eat fish and krill(磷虾).
　　The warming of the earth is the decrease in penguin populations. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖).　 Besides，many adult penguins die of hunger.
　　Widespread(广泛的) fishing，exploration for oil and oil leaks(漏) also make penguins be in danger. Poisonous organisms(生物) in ocean water are another danger. Penguins also have their enemies，including wild dogs，sharks，seals and sea lions.
　　News about penguins is not all bad，however. Several years ago，oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild.　 Now these South African penguins are reproducing in higher numbers than before the oil leaking.
【小题1】Penguins ___________.

A．can swim better than fly	B．can be found near Oceania (大洋洲)
C．eat fish only冬腊月	D．live only in cold waters.

【小题2】Which of the following is NOT the cause of penguin's decrease in numbers?

A．Oil searching.	B．Widespread fishing.
C．Human's killing.	D．Warming of the oceans.

【小题3】 Why are the penguins in South Africa reproducing in higher numbers than before the oil leaking?

A．Because people removed the ship.

B．Because people sent a lot of penguins to the wild.

C．Because people helped the penguins.

D．Because people treated the penguins well.

BEIJING--Lights went out for an hour at some famous landmarks and homes all over the world on March 28 for Earth Hour 2010. It is a global event created by the WWF(World Wildlife Fund) to make people pay more attention to climate change.

From the Sydney Opera House and Harbor Bridge to the Eiffel Tower in Pari sand London's Houses of Parliament, lights went out to encourage people to cut energy use.

Organizers said the action showed that a great number of people wanted the government to take measures to fight global warming by the end of 2010. "We have been dreaming of a new climate deal for a long time," said Kim Carstensen, head of a global climate organization. "Now we're no longer alone with the dream. We're sharing it with all these people turning off their lights," he said.

Australia first held Earth Hour in 2007 and it went global in 2008, attracting 50 million people. WWF is hoping one billion people from 1,000 cities in nearly 90 countries will take part in the event.
