Since January 2013, many cities in China have seen a lot of foggy days. In Beijing, only five days in January were free of smog (雾霾). What’s the difference between fog and smog?
According to scientists, fog is made up of tiny (微小的) drops of water and also ice particles (颗粒) during very cold conditions. Smog is dirty air that looks like a mixture of smoke and fog, caused mainly by smoke from cars and factories in cities.
An official for the Ministry of Environmental Protection told Beijing News that PM2.5 pollution is the main problem with air pollution. PM 2.5 refers to pollution with small particles 2.5 micrometers or less in diameter (直径).
According to the Chinese Academy of Sciences, two main factors that cause PM 2.5 are motor vehicles and the burning of coal.
Poor air has done harm to people’s health. Children and the elderly are more at risk. A report from Beijing Children’s Hospital shows that from January 5 to January 11, 2013, half of the patients in the hospital came for respiratory (呼吸道的) problems.
To respond to the air problem, the Chinese government and many Chinese people have started to take action.
Beijing announced a plan to use clean fuel in government vehicles and plant trees. It asked citizens to set off fewer fireworks for the Spring Festival celebration. They suggested that cars with large emissions (排放) should be banned and factories should be closely watched.
Three students from No. 4 High School in Beijing wrote a report to advise to fight the air pollution. “We hope more people will join us to protect our environment. With all our efforts, the blue skies will certainly return soon,” said Shi Yucong, 15, one of the three students.The underlined phrase “were free of” means ____________.

Seeing a volcano erupt (喷发) is a wonderful experience, and you can really feel the heat by climbing to the summit of Pacaya for a close-up view. There are guided tours every day up this highly active volcano from Antigua. Giving travelers a chance to see Mother Nature at her most powerful (强大的).
Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won’t miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2,560 metres high and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb, you hear the sounds of eruptions high above. Smoke, hot remains from recent eruptions begin to line the path as you near the active summit: the McKenney Cone (火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the safety of the old, inactive summit.
Many tours are timed so that you arrive at the cone of the volcano in plenty of time for sunset and the full scene of the erupting red lava (熔岩) in the darkening sky. On a good day the view from the summit is really exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot streams up to 100 metres into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night, the burning lava quietly falls down the side of the volcano. For you, too, it is time to get down.
| A．get down the mountain in time when night falls |
| B．avoid the smell from the upwind direction of the cone |
| C．enjoy the fantastic eruption against the darkening sky |
| D．appreciate the beauty of the 2,560-metre-high mountain |
| A．remained, cooled rocks along the path |
| B．loud sound and terrible smell in the air |
| C．the most exciting happening in a place |
| D．the top point of a mountain or hill |
| A．To have more tourists come to Pacaya. |
| B．To describe the beauty of Pacaya. |
| C．To introduce guided tours to Pacaya. |
| D．To explain the power of nature at Pacaya. |
You are watching a film in which two men are having a fight. They hit one another hard. At the start they only fight with their hands. But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes (撞击) through a window and falls thirty feet to the ground below. He is dead！Of course he isn't really dead. With any luck he isn't even hurt. Why? Because the men who fall out of high windows or jump from fast moving trains, who crash cars of even catch fire, are well trained. They do this for a living. These men are called stuntmen. That is to say, they perform tricks (花招，手段). Here are two sides to their work. They do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress (床垫). Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar! But although their work depends on trick of this sort, it also requires a high degree of skill and training. Often a stuntmen’s success depends on careful timing. For example, when he is "blown up" in a battle scene, he has to jump out of the way of the explosion just at the right moment.
Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously hurt, and sometimes killed. A Norwegian stuntman, for example, flew over the edge of a cliff (悬崖) a thousand feet high. His parachute (降落伞) failed to open, and he was killed. Although it is full of deadly dangers, this is no longer the work for men only. Men no longer dress up as women when actresses have to perform some dangerous actions. For nowadays there are stuntwomen too！ (357)
| A．often dress up as famous actors |
| B．prefer to lead dangerous lives |
| C．often perform dangerous actions |
| D．often fight each other for their lives |
A stuntman should _______.
| A．crash bravely though a window made of sugar |

| D．have got a high degree of skill and training |
| A．Fights in the Movies. | B．Crashing Out of the Window. |
| C．Exciting Films Today. | D．Most Dangerous Work. |
In the big cities of Europe and America — London, Paris, New York, people are moving out of the city. They are usually rich families with much money, and they want to live a quieter life.

They want a house with a garden, and clean air that is not polluted.
