China is going green. In order to reduce air pollu?tion and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles(混合动力车辆)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 on a recharge?able battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 per cent of their power when the car is cruising(匀速行驶).A specially designed bat?tery 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 tradi?tional car. At this point, the car's gasoline engine is dormant(休目民).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 on-board (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 char?ges the batteries. Any time you use the brake, the elec?tric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a conse-qiience, the car's batteries will last for around 200,000 miles.

Both of Jessica's parents were lawyers and expected her to follow suit. So she went to law school, got a job at a great firm in Washington D. C. and worked as a lawyer for a decade. But her heart was never in it. "I had a big salary but no personal satisfaction," she said.

Jessica found pleasure in the same thing that had brought her joy since joining the church choir at the age of 12.

She would spend her savingsf stud-y music for a year, and then open a part-time law prac?tice so she could pursue her passion. Before her mother passed away two years later, she encouraged Jessica to follow her dream. Her song Live This Life was inspired by her mum, and her dad came to watch her perform at clubs.
