With almost 5 million supporters and a global network in over 100 countries, it's one of the world's largest and most respected independent conservation organizations. WWF's mission is to stop the degradation of the Earth's natural environment and build a future where people live in harmony with nature. Earth Hour started on March 31st, in 2007 in Sydney, Australia when 2.2 million individuals and more than 2,000 businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had become a global movement with more than 50 million people across 35 countries participating. 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 by the hour. In March 2009, hundreds of millions of people took part in the third Earth Hour. Over 4,000 cities in 88 countries officially switched off to pledge their support for the planet, making Earth Hour 2009 the world's largest movement to stop global climate change. On Saturday 27 March, Earth Hour 2010 became the biggest Earth Hour ever. A record 128 countries and territories joined the global display of climate action. Iconic buildings and landmarks from Asia Pacific to Europe and Africa to the Americas switched off. People across the world from all walks of life turned off their lights and came together in celebration and contemplation of the one thing we all have in common--our planet. Earth Hour will continue to be a call to action to every individual, a call to stand up, to take responsibility and lead the global journey to a sustainable future. Question: The purpose of the text is to _ . - tell us what WWF does - advise us to take part in Earth Hour - introduce the movement, Earth Hour, to us - persuade us to take action to stop climate change
introduce the movement, Earth Hour, to us

Read the following article and select the best answer. Article: The car was invented just a century ago. You may know all kinds of cars' names, but many people don't know who was the inventor of the first car. The first car was invented not by an Englishman, but by an American. His name was Henry Ford. Henry was born in a poor family, He was the eldest of the six children. When he was a boy, he became interested in watches and machines. When he was twelve years old, his mother died. Soon he had to work in a machine shop for two dollars and fifty cents a week. In the evenings, he repaired watches for another hour for another dollar a week. The hard life made him strong and able. At that time, there was another interest in the life of the young boy. He hoped to make a machine. It could run without horses. He overcame a lot of difficulties and in April, 1893, the "horseless carriage" was invented at last. It was the first car. Later, Henry Ford set up the Ford Motor Company. He was the really first inventor of car in the world. Question: From Henry Ford's example we can see that _ . - Poverty is good for us - Hard work leads to success - His car is of high quality - His car is popular all over the world
Hard work leads to success

Q: Read the following article and select the best answer. Article: Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have documented how ant colonies choose their next queen--the female whose job is to produce eggs rather than seek food for others. New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned. Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide. David Hu who is a mechanical engineer with the Georgia Institute of Technology, also known as Georgia Tech, says, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at maintaining this network." David Hu and other Georgia Tech researchers want to study ants and the secret of their engineering. They freeze ant rafts and then look at them with the help of computed technology, or CT, images. The pictures show that larger ants serve in central positions to which smaller ants hold. The larger ants form pockets of air that keep the insects afloat. Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal. Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen. Question: The duty of the queen ants is to . - seek food - keep organized - lay eggs - keep guard
A: lay eggs

Read the following article and select the best answer. Article: These days, if you still think the cellphone is just for talking, you will get laughed at. Yes, it's true, voice-only handsets have become out of date. Today's do-it-all mobiles have a lot in common with the computer. The only difference may be that they fit in your pocket and you pay by the minutes to use them. Some of the things a cellphone can do for you will be available this year: Surf at speed Cellpones that let you use the Web have been around for years. So, what's new? Well, faster third-generation(3G) net works let you surf at anywhere. This then allows a carrier to send video, music, and games to your phone. Possible choices are from LG Electronic VX 8000 and Motorola V 1150. Listen as you go The problem with most cellphone MP3 players is that they hold only a handful of songs. But, that's about to change. Sony Ericsson's new W800i can hold around 150 songs in its 500 MB memory. And Sumsung's SPH-V5400 even comes with a 1.5 GB hard drive. Mobile phones may eventually replace mini-MP3 players, especially for teens. Say cheese Camera cellphones are not new either. But, most of them have limitations: around 1-megapixel . But new technology has made 2-megapixel units more common and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K750i, offer limited zoom and focus controls. Others, like LG's recent MMA7110, can even capture 30 minutes of full- motion video. Portable TV You say you like "watching TV"? That's what Sumsung MM-A700 wants to give you. The new model lets users watch popular TV programs--for a fee. Other choices are Nokia's 6620, Sanyo's MM 7400 and NEC's N940.The NEC model lets you watch public TV--no fee. The above are just a handful of what you will see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator... So what is there that a cellphone can't do? Question: Which of the following statements is TRUE according to the passage? - All the functions of the models mentioned in the passage are completely new - Camera cellphones of 3-megapixel units will appear soon. - It is certain that a cellphone can do anything in the near future - Today's do-it-all mobiles have nothing in common with the computer
Camera cellphones of 3-megapixel units will appear soon.
