Many people once thought that air pollution had a bad influence upon only the area immediately around large cities with factories and heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is nearly worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of factories and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide( 二氧化碳) in the air resulting from the burning of fossil fuels (coal and oil) is creating a“greenhouse effect” － holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another opinion, less widely held, is that increasing tiny substances in the atmosphere are blocking sunlight and lowering the earth’s temperature－a result that would be equally disastrous.A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will make up for each other and the world’s temperature will stay about the same as it is now.

Most people who travel from China to the US find that, despite having studied English for years, they have to “re-learn” it upon arriving.
Words that we learned in English classes are not pronounced the same way here. To truly be part of the “melting pot”, fluency in English is not enough. You need an accent to stand out.
When I first came to the US for graduate school, I was a nervous foreigner. I felt so out of place that I wanted to hide everything about me that was “different”. To talk like an American became one of my goals.
During my first term as a teaching assistant (TA), my students complained they could not understand me. I learned later from a study that this complaint was common among US students with an international TA．It is called the “Oh, no!” syndrome (情绪、举动): “Oh，no! Not another international TA, and not that accent again!’’
So I imitated（模仿）the way native speakers talk and, over time, I made such good progress that American friends started to praise my English as having “almost no accent’’. I took this as a sign of my success. Ever since, people have often mistaken me for someone from many places: the Midwest, the West Coast, China, Japan, South Korea. Most frequently, people think I am from California.
Suddenly, conformity ( 一致) was no longer a praise: If I talk like an American ， am I still Chinese? If I lose my Chinese accent, do I also lose my cultural identity? Am I denying my past by being absorbed into a new culture?
Now I realize that a person’s accent is a permanent record of their past cultural experience and it is amark of one’s experience and exposure to different cultures.
As a fourth-year student in the US，I am no longer a nervous foreigner. My nervousness has been replaced by a desire to hold on to my cultural origins. Now I consciously add some Chinese“accent” when I speak．I do not wish to speak “perfect” English because I am proud of who I am.

Several days ago, our school decided to prevent students bringing their cell phones to school if they don’t pass all exams from the previously semester. Students don’t welcome this decision.They believe the cell phone is one of the greatest invention in the 20th century, that have become an important part of modern life. Therefore it is also headache for school leaders. Because many students ignore our studies and spend too much time play games, texting and using social network apps such as Wenxin or Wechat. So the leaders have to deal with the serious problem by this way.They don’t expect that something even worse.
