Smog is a big problem in many Chinese cities. But it seems that besides wearing a mask (口罩), few of us know what has caused the smog and what to do to beat it. Chai Jing, former news anchor with Chinese Central Television, discussed the questions in her documentary Under the Dome (穹顶之下).
The 103-minute film was released on major Chinese video-sharing websites on Feb 28. In the film, Chai visits polluted places and talks to officials and scientists. She concludes that burning too much coal and oil are the main causes of PM2.5 and smog.
To make things worse, according to Chai, the coal and oil we are burning is of poor quality and doesn’t meet the standards (标准) for environmental protection. Therefore Chai says more harmful gas and particles (颗粒) have been produced to pollute the air. To solve the problem, Chai suggests that we should clean our coal and oil or replace(代替) them with cleaner energy such as natural gas.
In her film, Chai also suggested that we should do something to help control smog too. For example, she says we can live a greener life by using more public transportation. Or if we see things that harm the environment, we will try to stop it. In one scene from the film, Chai saw a dirt mound in a building site exposed in the air, she asked the person in charge to cover it. When she saw a restaurant cooking without any suitable filter facilities (过滤设备), she called the hotline 12369. The restaurant installed the filter a week later.
Chen Jining, the new minister of environmental protection, praised Chai. “This film encourages ordinary people to care for the environment. This is what we need in the future.”
Many people in China know the causes of smog, don’t they?
How long does the film Under the Dome last ?
What are the main causes of PM2.5 and smog?
Why does Chai say more harmful gas and particles have been produced to pollute the air ?

What do you think of Chai’s film? How should we control smog as an ordinary person? (at least two suggestions)

When I was growing up in America, I was ashamed of (感到难为情) my mother’s Chinese English. Because of her Chinese English, she was often treated unfairly. People in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.
My mother realized that she was poor at English. When I was fifteen, she used to have me call people on phone to pretend I was she. I was made to ask for information or even to shout at people who had been rude to her. One time I had to call her stockbroker(股票经纪人). I said in an adolescent(青少年的) voice that was not very certain, “This is Mrs. Tan.” My mother was standing beside me saying, “Why he doesn’t send me check, already two weeks late.” And then, in perfect English I said: “I’m getting rather worried. You agreed to send the check two weeks ago, but it hasn’t arrived.” My mother then talked more loudly. “What he want? I come to New York to tell him in front of his boss.” And so I turned to the stockbroker again, “I can’t accept any more excuse. If I don’t receive the check immediately, I am going to have to speak to your manager when I am in New York next week.”
The next week we ended up in New York. While I was sitting there red-faced, my mother, the real Mrs. Tan, was shouting to his boss in her broken English.
When I was a teenager, my mother’s broken English embarrassed(令人尴尬) me. But now, I see it differently. To me, my mother’s English is perfectly clear, perfectly natural. It is my mother tongue. Her language, as I hear it, is vivid, direct, and full of observation and wisdom. It was the language that helped me see things, express ideas, and make sense of the world.

I am a professor of sports and exercise so I often deal with nervousness in my research with sports people．Actually, most people experience nervousness at some time or another．
If you are feeling anxious, my advice is to first find the cause or causes．Make s list of those things that are making you nervous and work out which ones you can do something about．Focus all of your efforts on managing the causes that you can control．
Most people cannot tell the difference between controllable（可控制的） and uncontrollable causes, so things they can’t control become a big reason for nervousness．Dealing with this is very important if people want to keep a healthy mind．
Simply try to accept the uncontrollable causes of nervousness．You might be worried about the weather on a big day, an accident or an attack on the train, or perhaps just things that other people are doing at work．The results may be very important but there is still no use worrying because you can’t control any of these things．Accept that you can’t control everything．Once you understand this, it becomes easier not to worry．
If a situation, such as swimming, is causing you to be anxious, try to face it as often as possible so that you can get used to it．
It can often help to think about yourself doing the thing that make s you nervous—then close your eyes and imagine it going well．Imagine how the flight or job interview is going to happen so that you can get used to it．This will help you understand that the thing you fear most is probably not going to happen．

Taking away a city’s rubbish is a big job． Every day trucks come into a city to collect it．Most rubbish is made up of things we can’t eat or use．If we kept these things, we would soon have a mountain of rubbish．
In some cities the rubbish is collected and taken outside of city to a dump．Often the city dump is placed where the ground is low or there is a big hole．The kitchen rubbish is broken into small pieces and sent into the sewage system．The sewage system takes away the used water from toilets, bathtubs and other places．
To keep mice and flies away, some earth is used to cover the newly dumped rubbish．Later, grass may be planted on the rubbish-filled land．Finally , a house or a school may be built there, and then you’d never know that this had once been an old rubbish dump．
In other cities the rubbish is burnt in special places．The fire burns everything but the metal．Sometimes the metal can be used again in factories where things are made of metal．The food parts of rubbish are put in special piles where they slowly change into something called humus, which looks like black earth．It is rich with kinds of things that feed plants and help make them grow．

We were standing at the top of a church tower．My father had brought me to this high tower in a small town not far from our home in Rome．I wondered why．
“Look down, Elsa," Father said．I gathered all my courage and looked down．I saw the square in the center of the village．And I saw several streets leading to the square．“See, my dear,”Father said gently．“There is more than one way to the square．Life is like that．If you can't get to the place where you want to go by one road, try another．"
Now I understood why I was there．Earlier that day I had begged my mother to do something about the bad lunches that were served at school．But she refused because she could not believe the lunches were as bad as I said．
When I turned to Father for help, he would not help．Instead, he brought me to this high tower to give me a lesson．By the time we reached home, I had a plan．
At school the next day, I poured my lunch soup into a bottle and brought it home．Then I asked our cook to serve it to Mother at dinner．The plan worked perfectly．She tried one spoonful and sputtered．“The cook must have gone mad!” Quickly I told what I had done, and Mother promised that she would take up the matter of lunches at school the next day!
In the years that followed I often remembered the lesson Father taught me．I began to work as a fashion designer two years ago．I wouldn’t stop working until I tried every possible way．Father’s wise words always remind me that there is more than one way to the square．
