A recently study found people's lives are made shorter in North China. It is showed the life expectancy(平均寿命) had been cut down by 5.5 years there. Researchers think that the heavy air pollution in China should be to blame. It's really the truth. Our government has already done something. However, it doesn't seem to work so well.

“Air pollution in China is doing harm to people's health. The harm is much more serious than we can imagine,” said Chen Yuyu of Beijing University, one of researchers of this study.

Dirty air brings serious problems in North China. In January this year, the air pollution was worse than that in other places. That was caused by rising temperature and waste gas from coal heating.

Chinese government should strongly fight against air pollution. They should think of more proper ways to deal with the problem. People should be encouraged to take buses, ride bicycles or walk, instead of driving cars. The factories that pollute heavily should be closed.

“We need to improve our environment, although it might be expensive. Protecting our environment means protecting ourselves,” Li Hongbin, another researcher of the study said.

（1）、The passage above may come from an advertisement.

（2）、The study showed the life expectancy had been cut down by 5.5 years in North China.

（3）、Air pollution is very harmful to people.

（4）、People shouldn't be encouraged to take more transportation .

（5）、People need to make pollution less, although it might cost a lot.

    For hundreds Of years, scientists have been trying to answer what things have an effect on people's emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don't know your emotions can be influenced by the weather as well.
    People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
    The weather can also affect people's emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.

   People cannot reach an agreement on the use of science and technology. For example, will radiation from electronic equipment destroy the environment? Should medical scientists change gene structures to prevent genetic disease or to create “more perfect” human beings? While people are arguing about these and others, technology continues to influence our everyday lives—the home, health and education, entertainment and communication, and so on.
   Some people carry on active social lives with computers —their own or the ones in public places like cafes, social centers, libraries, and so on. Communicating with others in chat rooms, computer users can get to know people they might never meet in traditional ways. With live online video connections, two people with cameras in their computers can see and talk to each other from separate places.
   With modern telephone technology, most people stopped writing lettters—especially personal letters and notes. But now, writing to communicate has returned in electronic form, or e-mail, which is a way of sending messages from one computer to another. For some computer users, the wish to communicate intelligently or creatively with others makes them want to write better.
   Computer technology has also made it possible to run a house electronically. From turning lights on and off to starting the coffee and cooking the hot meal, computers are taking care of people at home. Many modern machines have computer chips that allow their owners to program them. For instance, you can “instruct” a microwave oven how to cook a dish. Most entertainment equipment operates with computer technology too. Computers can even start cars automatically so that on cold winter mornings you can get into a warmed-up vehicle and drive off.
   Although much of the technology in our everyday lives has good effects, there are some uses that raise questions. For example, are interactive media ( i.e., a combination of television, telephone, and computer) going to control minds, cause people to forget about family life and personal relationships? What effects will the genentic engineering of food have on people's health? High-tech medical treatments can make a person live a much longer life, but can they improve the health and happiness of human beings? Only time will tell, but, in the meantime, science and technology will continue to move forward.

    Steve Jobs, co-founder and former CEO of US technology giant Apple, has died at the age of 56. Mr Jobs had announced he was suffering from cancer in 2004. Apple said he had been "the source of countless innovations（创新）that enrich and improve all of our lives" and had made the world "immeasurably（无法衡量的）better".
    Tributes(赞美之辞) have been made by technology company bosses and world leaders, with US President Barack Obama saying the world had "lost a visionary（有远见卓识的人）". "Steve was among the greatest of American innovators —— brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it," said Mr Obama.
    A statement from Mr Jobs's family said they were with him when he died peacefully on Wednesday. "In his public life, Steve was known as a visionary; in his private life, he loved his family deeply," they said, requesting privacy and thanking those who had "shared their wishes and prayers" during his final year.
    Apple said the company had "lost a visionary and creative genius(天才) and the world have lost an amazing human being". Tim Cook, who was made Apple's CEO after Mr Jobs stood down in August, said his predecessor had left behind "a company that only he could have built, and his spirit will forever be the foundation of Apple". Flags are being flown at half mast outside the Apple headquarters（总部） in Cupertino, California, while fans of the company have left tributes outside Apple shops around the world.
    The heads of other leading technology companies have also paid tribute, including Microsoft boss Bill Gates, who said "For those of us lucky enough to get to work with him, it's been a great honour. I will miss Steve very much."
    Facebook founder Mark Zuckerberg thanks Mr Jobs for "showing that what you build can change the world" while Sony Corp president and CEO Howard Stringer said: "The digital age has lost its leading light." South Korea's Samsung, which is involved in a case with Apple over patents(专利), admired Mr Jobs for his "Completely new and different changes to the IT industry".

    Many animals do strange things before an earthquake (地震). This news may be important. Earthquakes can kill people and knock down homes. The animals may help to save lives.
    Some animals make a lot of noise before an earthquake. Farmers have told about this. Dogs that are usually quiet have started to howl(吠). Horses on farms have run around in circles. Mice have left their holes and run away. Cows have given less milk.
    In a town in Italy, cats raced down the street in a group. That happened only a few hours before an earthquake. In San Francisco, a man kept tiny pet frogs. One Sunday, the frogs jumped around more than ever. They made loud noises, like bigger frogs. That night, an earthquake struck the city.
    People want to know when an earthquake is coming. Then they could get away safely. Right now, there is no sure way to know ahead of time. Maybe the best way is to watch the animals.

Carbon monoxide poisoning (一氧化碳中毒) causes death and injuries around the world. This gas is a problem in all parts of the world that experience cold weather. A few years ago, America's Centers for Disease Control (C. D. C.) studied deaths linked (联系) with carbon monoxide poisoning. It found that the number of carbon monoxide deaths in the United States was greatest in January. The C.D.C. also found that carbon monoxide kills more than four hundred Americans each year. And, it said more than twenty thousand people are taken to hospital for treatment of health problems linked with the gas.
Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color, no taste and no smell. It does not cause burning eyes. And it does not cause people to cough. Yet, carbon monoxide gas is very deadly (致命的). It steals the body's ability to use oxygen.
Carbon monoxide makes it difficult for the blood to carry oxygen to body tissues (血管). It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage (损害) to the body can begin very quickly from large amounts (数量) of carbon monoxide.
How quickly this can happen depend on how long a person is breathing the gas and how much gas he or she breathes in.
Carbon monoxide poisoning has warning signs(标志). But people have to be awake to realize them. Small amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. Their stomachs may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly.
People develop serious headache as the amount of the gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomachache.
Doctors say carbon monoxide influences people differently. For example a small child will experience health problems or die much sooner than an adult. The general health of the person or his or her age can also be important

My dear boys and girls, good morning. Today I'm going to talk to you about my suggestions about how to become stronger.

As the high school entrance examination is coming soon, you might feel a bit worried or nervous. These feelings may make you stressed out and fail to focus on your studies. But think about it. Would your favorite superhero have these same feelings?

Scientists have been studying what they call the "Spider-Man Effect" (蜘蛛侠效应) in children. They've found that if kids imagine themselves as a powerful person—such as a super hero like Spider-Man, they won't feel so nervous and will be able to focus on their work.

For example, if you feel nervous during an exam, try to imagine that you are a Spider-Man. You may find that you can "remove" the stress from this situation and feel more confident. This can help keep you fight off bad feelings and focus on your task, just like a superhero would. Pretending to be a superhero makes us feel powerful and that will have an influence on how we act in real life.

But you don't have to always choose a superhero like Spider-man. Anyone you admire can encourage you to get through hard times, or remind you of how you should act in certain situations. Favorite stars, famous painters, even our own parents—anyone can be our "Spider-Man". For example, when it comes to how I communicate with others, I like to look toward my mom for inspiration. She is a middle school teacher who is always kind, thoughtful and brave. I try to act the same way like her.

Thanks for your listening. I hope you can find your own strength to deal with the difficulties in your life.
