Iceland has energy to spare, and the small country has found a cutting-edge way to reduce its oil dependency. Volcanoes formed the island nation out of ash and lava , which heat huge underground lakes to the boiling point. The hot water is piped into cities providing heat for homes, businesses and even swimming pools. The water runs through turbines , providing all the country's electricity. prefix = st1 /Icelandwants to make plans to improve its cars, buses and trucks to run on renewable energy. Iceland has already started by turning water into fuel ----hydrogen fuel. Here's how it works: Electrodes change the water into hydrogen and oxygen molecules . Hydrogen electrons pass through a conductor that creates the current to power an electric engine. Hydrogen fuel now costs two to three times as much as gasoline, but gets up to three times the distance than gas, making the overall cost about the same. As an added benefit, there is no carbon ----only water steam. In the capital,Reykjavik, they are already testing three hydrogen-powered electric buses. The drivers are impressed. "I like these buses better because with hydrogen you get no pollution," said bus driver Rognvaldur Jonatanison. By the middle of this century, all Icelanders will be required to run their cars only on hydrogen fuel, meaning no more gasoline. "If we make hydrogen and use that as a fuel for transportation then we can run the whole society on our own local renewable energy sources,"said Marie Mack. Icelanders are showing the world that by making fuel from water, it is possible to kick the oil habit. The cars with hydrogen as fuel _ . A) are environmentally friendly B) are cheaper C) run much faster D) will make useful steam

Dear Customers, I love slipping into a comfortable chair for a long read--as I relax into the chair, I also relax into the author's words, stories and ideas. The physical book is so elegant that it disappears into the background, and what remains is the author's world. Today, we at Amazon are excited to announce Mindle, a wireless, portable reading device with instant access to more than 90,000 books, magazines and newspapers. We've been working on Mindle for more than three years. Our top design objective was for Mindle to disappear in your hands--to get out of the way--so you can enjoy your reading. We also wanted to go beyond the physical book. Mindle is wireless, so whether you're lying in bed or riding a train, you can think of a book, and have it in less than 60 seconds. No computer is needed--you do your reading directly from the device. We chose the same wireless technology used in advanced mobile phones. But unlike mobile phones, there are no monthly wireless bills, no service or data plans, and no yearly contracts. There is no software to install (,). We want you to get lost in your reading and not in the technology. Mindle uses a new kind of display called electronic paper. Sharp and natural with no strong light, reading on Mindle is nothing like reading from a computer screen. Mindle weighs only 10.3 ounces--less than paperback--but can carry two hundred books. Enjoy learning about Mindle and many thanks! Jeff Bezos Founder & CEO With the device, the reader is able to _ . A) enjoy reading when driving a car B) improve reading skills C) gain access to free software D) get rid of heavy books made of paper

Q: This is a true story about a boy who, the world might say, was a terrible underachiever. While in the eighth grade, he failed subjects repeatedly. High school wasn't much better; he _ Latin, algebra, English, and received a grade of zero in physics. The boy managed to make the school golf team, but he lost the most important golf match of the season. It's not that his peers disliked this boy; it's just that they never really seemed to notice him much. Even "Hellos" in the hall were a rarity. Out of all the failures in his life, there was something that did hold great importance to this boy, his love of drawing. Although in high school, the cartoons he submitted to the yearbook were rejected, once out of school, the boy was so sure of his artistic talent that he approached Walt Disney Studios with drawing works. I wish I could say the studios loved his work and immediately hired him, but such was not the case; another huge rejection. Despite his lack of successes, this boy did not give up. He then decided to write his own autobiography in cartoons, about a little boy who was regarded as a loser and a nobody. The name of this boy was Charles Schulz, the creator of the famous Charlie Brown and comic dog Snoopy. In life, it is sometimes easy to feel like a nobody. We pass hundreds of people on the street on our way to work, or walk through a faceless crowd in a mall, and no one seems to notice or care. Deep inside, we may know we are special and unique and have lots to offer, but unless someone takes the time to look our way and give us a chance, we may feel worthless, just like Charlie Brown who couldn't even manage to fly a kite or kick a football properly. Just as Charles Schulz had faith in his artistic talent, so too, we must realize that nobody is a nobody. We all have special gifts and talents, and every human being is deserving and capable of being loved and appreciated. When the boy suffered many defeats, he _ . A) gave up his dream finally B) wrote some articles in magazines C) he turned to others for help D) he wrote himself as a loser in cartoons

Q: Check out our tsunami facts and learn some interesting information related to these great walls of water that can cause so much destruction. Find out what causes tsunamis and read about some recent examples of tsunamis that have occurred around the globe. The Japanese word for tsunami means harbor wave. Tsunamis are sometimes called tidal waves but this term has fallen out of favour because tsunamis are not related to tides. Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions. As a tsunami approaches the shore, water may move back from the coast. If it is shallow enough the water may be pulled back hundreds of metres. If you are in the area, you can know that a tsunami is on the way when you see this phenomenon. Regions in tsunami danger zones often have warning systems in place to give people as much time as possible to move to a safe place. When tsunamis hit shallow water (often near the coast) they slow down but increase in height. An earthquake in the Indian Ocean off Indonesia in December 2004 caused a tsunami that killed over 200,000 people in 14 countries. In March 2011, the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15,000 people. The tsunami waves created by the Tohoku earthquake reached a height of over 40 metres in some areas, wiping out coastal towns and causing a number of nuclear accidents. How many causes of tsunamis are mentioned in the text? A) One. B) Three. C) Two. D) Four.
