牋 A hybrid car is a combination of a regular car that runs on gas and an electric car that is battery powered. Some people tend to think that sinrce the hybrid car is partly electric, you have to plug it in to charge it. But that’s not how it works. Through the energy that is produced when the car’s brakes are used. This is referred to as “regenerative braking（再生制动）,” because it generates electricity.

　　Although the hybrid car still runs on gas most of the time, this helps it use less gas than a regular car. when a driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear（处于正常工作状态）and touches the gas pedal, the engine starts back up.

　　Have you ever ridden in a car with someone who ran out of gas? That probably would not happen if you were riding in a hybrid car. It flashed a warning reading: ?You are now out of gas!?Then the electric power supply energy in to let the driver travel a few more miles to a gas station.
