     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.
