  After years of research and testing, the hybrid car was developed and put on the market.It’ san interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and conserve(保持)our natural resources.

  The quality of our air is affected by many different things.But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car's engine.The EPA has set national standards to help control the level of harmful pollutants sent off into the air ,and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

  A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered.Some people tend to think that since the hybrid car is partially electric, you have to plug(接通電源)it in to charge it.But that's not how it works.The 144-volt battery pack is actually recharged through the energy that is produced when the car's brakes are used.This is referred to as "regenerative braking", because it generates electricity.

  Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car.When the 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 and touches the gas pedal, the engine starts backup.

  Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car.It flashes a warning on its computer screen that says, "I am low on gas".When it completely runs out, the warning reads,"YOU ARE NOW OUT OFGAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

  To extinguish(熄)different kinds of fires, several types of fire extinguishers(滅火器)have been invented.They must be ready for immediate use when fire breaks out.Most portable(手提式的)kinds operate for less than a minute, so they are useful only on small fires.The law requires ships, trains, buses and planes to carry extinguishers.

  Since fuel, oxygen(氧氣)and heat must be present for fire to exist, one or more of these things must be removed or reduced to extinguish a fire.If the heat is reduced by cooling the material below a certain temperature, the fire goes out.Water is the best cooling material because it is low in cost and easy to get.

  Another method of extinguishing fire is by cutting off the oxygen.This is usually done by covering the fire with sand, steam or some other things.A blanket(毯子)may be used to cover a small fire.

  A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.

  The method that is used to put out a fire depends on the type of fire.Fires have been divided into three classes.Fires in wood, paper, cloth and the like are called C1ass A fires.These materials usually help keep the fire on.Such fires can be stopped most easily by cooling with water.
