HAVE you ever thought of being able to fly around the world in a few hours though it is about 40,000 kilometers? Now, maybe you can. Last Saturday, the American X-43A airplane made its first flight. It reached a speed of 8,000 kilometers an hour. This makes it the fastest plane in the world. X-43A is only three to four meters long,but it's very heavy: it weights 1,270 kilos.      HOW old cart an insect be? 400 million years! Last Wednesday, scientists found the world's oldest insect fossil (化石) in Britain. The fossil shows that the body of the insect was as big as a piece of rice and had wings (翅膀). In the past, people thought the earliest insect was 380 million years old.     THERE will be a new "star" in the sky soon. China plans to send a satellite (卫星) into space by September 2009. It will stay in space for one year. It will go around the moon and take pictures. It must be very expensive, right? That's for sure-1.4 billion yuan!      Yuan Longping, the father of hybrid rice (杂交水稻), won the World Food Prize on Monday. Yuan developed the world's first popular and widely grown hybrid rice. Hybrid rice plants can make more rice than the ones people grew before.
