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.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 |
“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 |

| C．They set important guidelines that help control pollution. |
| D．Their main purpose is to protect endangered plants and animals. |

Mr Smith was the manager of a hotel in Springfield. One weekend all of the hotels in the city were full because there was a large meeting. Late in the evening three men came into the hotel and asked for rooms. Mr Smith explained that because of the meeting, there were no rooms ready for use. The men were very unhappy because they had no place to stay in.
Mr Smith wanted to help them. He remembered that Room 414, a very small room, was empty. He asked them if they would share a room. The three men agreed. Mr Smith told them that the room would cost $30: $10 for each. Each of them gave Mr Smith $10, and they went up to the room.

Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”(燃料). Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein, like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you will feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (个性). Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise makes the body strong and and prevents you from putting on weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on, are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

There is an English saying:“ laughter is the best medicine.” Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter had similar effects to physical exercise. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial .
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain .
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.Doctors have proved the following EXCEPT that____ .
| A．smiling does good to health |
| B．laughter can be tolerated |
| C．there is a way to reduce pain |
| D．laughter can work the muscles in the feet |
.The main idea of the passage is .
| A．laughter and physical exercise have similar effects on the human body |
| B．smile can produce the same effects as laughter |
| C．pain can be reduced by laughter |
| D．laughter is the best medicine |
The students who___ tolerated the pain for the longest time .
| A．listened to different radio programs |
| B．slept in the room |
| C．don’t have stress of pain |
| D．listened to a funny program |
The underlined word “diminish” is similar to_____ .
