The device spins and heats the material to remove the sweat, and then passes the vapor through a special membrane designed to only let water molecules get through. Since its Monday launch, its creators say more than 1,000 people have "drunk others' sweat(h)" in Gothenburg. They add the liquid is cleaner than local tap water. The device was built for the United Nation's child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water. The machine was designed and built by engineer Andreas Hammar, known locally for his appearances on TV tech show Mekatronik. He said the critical part of the sweat machine was a new water purification component developed by a company named HVR in collaboration with Sweden's Royal Institute of Technology. "It uses a technique called membrane distillation ," he told the BBC."We use a substance that's a bit like Gortex that only lets steam through but keeps bacteria, salts, clothing fibers and other substances out."They have something similar on the International Space Station to treat astronaut's urine - but our machine was cheaper to build. Volunteers have been sampling the treated sweat since the start of the week in Gothenburg ."The amount of water it produces depends on how sweaty the person is - but one person's T-shirt typically produces 10ml , roughly a mouthful." The equipment has been put on show at the Gothia Cup - the world's largest international youth football tournament. MattiasRonge, chief executive of Stockholm-based advertising agency Deportivo - which organized the stunt - said the machine had helped raise awareness for UNICEF, but in reality had its limitations. "People haven't produced as much sweat as we hoped - right now the weather in Gothenburg is lousy," he said."So we've installed exercise bikes alongside the machine and volunteers are cycling like crazy."Even so, the demand for... Question: What does Mattias Ronge think of the machine? _ Options: A: The machine can solve the severe water shortage in the world. B: People do not like the water the machine processes C: The machine should be used in rather hot areas in summer. D: The machine is not worth popularizing.

Natural resources are exhausted. That's what makes the Galapagos Islands so special--it's one of he few places on the Earth that nature can truly call its own. For people used to having wild animals run at the scent of humans, a visit to the Galapagos is a real eye-opening experience. Over 1,600 km west of Ecuador, the islands are home to a unique variety of animals that have absolutely no fear of people. Visitors can play on the beach with sea lions and giant sea turtles, swim with dolphins and whales, and get close enough to the penguins to count the eggs in their nests. The islands were declared a national park over 40 years ago, and the number of human visitors is tightly limited to avoid damaging he environment or putting stress on the animal. Tourists have to pay a $100 daily visitors fee, and can't step off the boat unless accompanied by an official guide. Once on the islands, you have to stay on the trail , but that seldom presents a problem: the animals are so curious about people that they'll usually come up to say hello. "It's a little like being in a zoo," said one traveler. "But instead of us looking at the animals, the animals, the animals are looking at us." Aside from the wildlife, one of the island' more unusual features is its post office. You can send postcards for free, but the problem is that there's no postman to collect them. Instead, travelers pick up mail addressed to people who live near them back home, and then hand-deliver the postcards when their trip is finished. Question: Which animal is NOT mentioned in the passage? Options: A: Whales. B: Sea lions. C: Goats. D: Dolphins.

Q: Read the article and select the best answer. Article: Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor and the type of home you have is another. Things like insulation , present energy costs, and the type of system you buy are added factors. Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. Sooner or later Mother Nature will say that's all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun. We won't have to worry about the sun's running out of energy for another several billion years or so. Besides, the sun doesn't offer as many problems as other energy sources. For example, fossil fuel adds to already high pollution levels. With solar energy, we will still need sources of energy, but we won't need as much. That means we can cut down on our pollution problems. With all these good points, why don't we use more solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy. All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed . Solar energy is now in its infancy . It could soon grow to become a major part of our nation's energy supply. Question: What's this passage mainly about? Options: A: Something about solar energy and pollution. B: Solar energy. C: Energy and pollution. D: Energy and money.
A: B
