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.

But it’s not enough for a man to learn some kind of work. He should put his heart and soul (精力) into his work, and not waste his free time. “Work while you work and play while you play” is as good rule for young people as old.
There is no better to help to diligence than the habit of early rising, and this, just like all other good habits, is most easily formed in youth (青年). There is an English say “Lost time never returns.” This means that everybody must be diligent, and make good use of time. One must study hard when one is young so that one can make great progress, succeed in life and become useful to one’s country. So we can say that diligence is the mother of success.

| A．惜时 | B．勤奋 | C．失败 | D．智慧 |
| A．learn some useful work |

Hundreds of years ago, life was much harder than it is today. People didn’t have modern machines. There were no modern machines, either. Life today has brought new problems. One of the biggest is pollution. Water pollution has made our rivers and lakes dirty. It kills fish and affects(影响) our drinking water. Noise pollution makes us talk louder and louder. Air pollution is the most serious kind of pollution. It affects every living thing in the world.
The world is not only hungry, but it is also thirsty for water. Only if we take steps to deal with this problem now can we avoid(避免) a serious worldwide water shortage later on. We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways of reusing it. But even if we purified(净化) and reused the water, we still would not have enough. All we’d have to do is to make use of the vast reserves(储备) of sea water in the world is to remove the salt.
Paper comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchiefs(手帕) and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper bag, we can save it and reuse it later.

New traffic laws (交通法) say that if people cross the street when the light is red, they can be fined as much as 50 yuan.
Traffic accidents killed more than 104,000 people in China last year. Chinese cities have more cars than ever. Drivers and pedestrians (行人) must work together to make the streets safer.
The law has new rules for drivers and pedestrians. Drivers have to slow down when they are close to crosswalks. If people are in a crosswalk, cars must stop to let them pass.
There are rules for bus drivers, too. If bus drivers smoke, drink or make phone calls while driving, they can be fined. Buses that carry too many people are also against the law.
Pedestrians will have to walk more safely under the new law. They must cross streets at crosswalks. Also, they shouldn’t climb over the fences (栅栏) along streets.
Do you bike to school? It’s not a good idea to carry classmates on the back. You could be fined 50 yuan.
And stay in the bike lane (慢车道) when you’re riding. The big roads are for cars and buses.
Do you like to ride your uncle’s motorbike? When you put on your helmet (头盔), ask him to put one on, too. People on motorbikes must wear helmets, the new law says. If they don’t, they’ll have to pay 200 yuan.
Do you ride in cars often? Don’t forget to put on your seat belt (安全带), even if you’re going for a short taxi ride. It could save your life.
If you see a hit-and –run (肇事逃逸), tell the police. They may give you a reward (奖赏). And don’t be afraid to help people to the hospital if they are hurt in an accident. Don’t worry about money. The new law says that doctors must take care of them even if they can’t pay right away.
