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 (霧霾). 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 (顆粒) 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 (直徑).
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.

You want to run across the street to catch the bus which is leaving soon? But wait! You’d better not. If a policeman sees you, you’ll have to pay a fine (罰款).
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 (柵欄) 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 (慢車道) 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 (頭盔), 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 (安全帶), 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 (獎賞). 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.

In one way, it may be thought that failure(失。﹊s a part of life. In another, failure may be regarded as a step towards success.
The "spider-story" is often told as an example of this. Robert Bruce, leader of the Scots in the 13th century, was hiding in a hole on a hill from the English. He watched a spider(蜘蛛) making a web. Bruce is said to have got confidence from this and to have gone on to beat the English. Edison, too, the inventor of the light bulb(電燈泡) , made hundreds of models that failed before he found the right way to make one.
So what? First, always think about your failure. What caused it? Were you in high spir¬it then? What can you change so that things will go right the next time?
Second, is the goal(目標(biāo)) you are trying to reach the right one? Try to do some thinking about what your real goals may be. Think about this question: "If I am successful in this, where will it get me?" This may help to prevent failure in the things you shouldn't be doing anyway.
The third thing to remember about failure is that it's a part of life. Learn to "live with yourself” even though you may have failed. Remember, "You can't win them all. “
小題1:Robert Bruce was mentioned in the passage to show that        .
A.people who fail are not lonely
B.a(chǎn)nimals can help people sometimes

小題2:Edison's example shows us that        .
A.he liked to do other kinds of work
B.he invented many kinds of light bulbs
C.failure may be a way towards success
D.he was a man of many important inventions
小題3:If you are not sure about what success will get you, you'd better         .
A.change your goalB.go on with your goal
C.not care for thatD.work even harder on your goal
小題4:It can be learned from the passage that        .
A.one should try not to fail
B. one's failure is another's success
C.one should take failures seriously
D.one should learn lessons from failures

Lost Cat Returned To Owner 12 Years Later

April 3, 2014 – Linda Edwards of Las Vegas, Nevada is full of happiness because her long lost cat Spaz has been returned to her – 12 years after he first went missing!
Spaz first went missing in 2002 and Edwards looked for him every day for three months. She searched all around her town and even wrote letters to some newspapers for help and was never able to find him. At the end of the three months, on New Year’s Eve of 2002 her searching stopped.
But someone recently discovered a dirty, thin stray cat (流浪貓) and took him into a West Flamingo Animal Hospital. The people working in the hospital checked the cat and were sure enough that his name was Spaz and he belonged to Edwards!
“An old lady found a kitty on Sunday and brought him here. We scanned (掃描) him for a microchip (微芯片) and we were able to find out his owner. The kitty, whose name is Spaz, has been missing for 12 years!” the animal hospital wrote on their Facebook page early last week.
Microchipping pets is a way to recognize if a stray animal belongs to anyone who could be missing them. Microchipping pets allows animal services to learn if they have a family waiting for them. Microchips are only about the size of a grain of rice and can only be removed by operation.
Edwards is very thankful she had Spaz microchipped and was so excited to get him back!
“I feel like I have a second chance,” she said. “This would have never happened if it weren’t for microchips.”
小題1:The cat got lost ______.
A.three months agoB.12 years ago
C.on April 3, 2014D.on New Year’s Eve, 2002
小題2:After the hospital checked the cat, they knew ______.
A.its feelingB.its hobbyC.its stray lifeD.its owner’s name
小題3:______ make(s) it possible for owners to find their lost pets.
A.The microchip B.Animal hospitals
C.The newspaper D.Family members
