After years of research and testing, the hybrid car was developed and put on the market. It’s an 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 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 are 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 it in to charge it. But that’s not how it works. The 144 volt battery pack is actually recharged( 充电 ) 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 ( 自动地;机械地 )shuts off to save fuel. Then, as soon as the driver puts the car in gear 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 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 OF GAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

1.According to the passage, the word “hybrid” refers to ________.

A. a high tech discovery B. energy saving

C. a new invention D. a combination of two things

2.“Regenerative braking” is an important process of the hybrid car because ________.

A. it allows the car to come to a quick stop

B. it gives the driver a smoother ride

C. it produces energy to charge the battery

D. it can control the speed of the car

3.Which of the following is right about the EPA?

A. They designed hybrid cars.

B. They outlawed (宣布……为不合法) the burning of fossil fuels.

C. They set important guidelines that help control pollution.

D. Their main purpose is to protect endangered plants and animals.

4.Which of the following is the reason for developing hybrid cars?

A. They use less gas than regular cars.

B. They’re safer to drive than most cars.

C. They’re more modern than other cars.

D. They cost less than regular cars

About nine million people like rock climbing in America. Millions more take part in the activity around the world. Some do it just for fun. Others compete.

Climbing takes strength, control and good balance. Climbers have to pull themselves straight up the face of very high rocks or walls. So they have to be strong enough to carry their own weight. And climbers sometimes have to hold onto rocks by only their fingers or toes.

There are several kinds of rock climbing. Traditional rock climbing is done outside. Climbers wear ropes and tie equipment to the rocks as they climb many hundreds of meters up. They also connect their ropes to the equipment. If a climber slips, a rope can stop him from falling.

Sport climbing is similar. However, in it the protective equipment is placed in the rock all the time. There is also indoor climbing. Rock walls made of wood have places for the climber’s hands and feet.

Ice climbing is exactly as it sounds. People climb glaciers or frozen waterfalls instead of rocks. They use special equipment for the ice.

And then there is bouldering-climbing rocks (巨石攀岩) between three and seven meters high. It is quicker and stronger climbing. Many climbers like bouldering because they can use less equipment. Climbers often need only special shoes and chalk (防滑粉). All climbers use chalk to keep their hands dry.

Most rocks have cracks and holes and parts that stick out. Climbers use these for foot-holds and handholds. Climbers use their legs to climb. They try not to pull themselves up with their hands or arms. Arms and hands are for position and balance.

People almost always climb in groups of two or more. Climbing alone is very dangerous. Expert rock climbers say only the very best in the sport should do it.
