In China he’s known as “the Flying Fish”; in America they call him ‘the Baltimore Bullet’.
Whatever you call him, American swimmer Michael Phelps looks destined (命中注定) to become a household name across the world after breaking the Olympic record for most gold medals in a single Games.
Phelps’s total of eight gold medals in Beijing put him one ahead of Mark Spitz’s previous record set in 1972.
Now people are already calling him the greatest Olympian of all time. But whether he is or not, what is it that makes Michael Phelps so good?
A good place to start might be his physique. Phelps has the perfect body shape for a swimmer: his arm span is longer than his height, he has very flexible joints, huge lungs, and his incredibly large feet (size 14 in the US, size 49 in China) act like flippers in the water.
To feed his huge swimmer’s body, Phelps eats an astonishing 12,000 calories a day, six times the average for a man of his age.
He then owes it to a swimsuit which has been making waves in the world of swimming. Designed by NASA, the American space agency, the suit is made of a special material which is said to help athletes swim 2% faster.
Michael Phelps should spare a thought for his mum, who first pushed him into swimming as a way of making friends, and who believed in him when one teacher said he would never be a success.
Whatever the reason for his success, Phelps admits there was perhaps also a bit of luck involved in winning his eight medals.
“I guess eight is a lucky number for me, too, now. The opening ceremony started on 8/8/08. Maybe it was meant to be.” he said.

China_is_going_green. In order to reduce air pollution and oilshortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(车载的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
