A Solar-powered Plane---Lowcarbon Earlier this month, a solar-powered (太阳能动力的)plane called Lowcarbon took off to the sky for the first time. It has passed an important test on the way to travel around the world. Lowcarbon took off from an airport in Switzerland(瑞士)at 45 km an hour. It slowly rose into the sky. “There has never been an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project. During the 90-minute flight, Lowcarbon did several turns. It climbs nearly 1.6 km above the countryside. Engineers plan to test a night flight in July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012. “We want to fly it day and night with no fuel,” Piccard said. Piccard and pilot Andre Borschberg will take Lowcarbon around the world .They will make a few stops to change places and rest after a long time in the air----and to show off their aircraft. Lowcarbon flies at 70 kph on average(平均). That is faster than a bike and slower than a car. The pilots will keep it in the air for up to five days at a time.

For hundreds Of years, scientists have been trying to answer what things have an effect on people’s emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be influenced by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
