A solar-powered（太阳能动力的）plane has passed an important test on the way to travel around
the world. The plane took off from an airport in Switzerland at 45km an hour. It slowly rose above the
fields and into the sky. During the 90-minute flight, the plane did several turns. It climbed nearly l.6km
above the countryside.
"There has never been an airplane of that kind that could fly-never an airplane so big, so light, using so
little energy," said Bertrand Piccard, a leader of the project.
Engineers plan to test a night flight soon. They plan to travel around the world in that plane in 2012.
"We want to fly it day and night with no fuel (燃料). " Piccard said.
Piccard and the pilot Andre Borschberg will take the plane 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.
The plane flies at 70 kilometers per hour on average. That is faster than a bike. The pilots will keep the plane in the air for up to five days at a time.

| Do you know why different animals or pests have their special colors? Colors in them seem to be used mainly to protect themselves. Some birds like eating locusts (蝗虫) , but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of" crops. When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night. If you study the animal life, you"ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters.
