Section A: Smog in My City
.
Smog is a type of air pollution that occurs when smoke or other pollutants in the air mixes with fog. The word “smog,” a blend of “smoke” and “fog,” was first coined in the early 20th century to describe the smoky fog that hung over London and some other large cities at that time. Unfortunately though, more than one hundred years later, smog remains a familiar sight in many places around the world, especially in big cities with a lot of industry and traffic.

Suggested answer:
Too many cars have caused a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol.

Suggested answer:
Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. Thus, the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.
B. Reduce the amount of coal and gas we burn C. Exercise tougher control on factories and
companies D. Use energy-efficient cars E. Reduce and recycle the waste we create F. Cut down on chemicals in farming G. Treat sewage before it enters rivers H. Educate people to avoid littering

Pollution is a major problem in the world today. It damages the environment and is harmful to humans, animals and plants. Although pollution can be a result of natural disasters such as earthquakes and forest fires, it is mostly caused by human activity. With the increase of population and the development of technology, pollution in our modern-day world has reached dangerous levels. Clean and fresh air is now a luxury in many big cities and the water in many of our rivers and lakes are too polluted to drink and swim in. The environment is our life support system—the only one that we have. We should do our best to save it before it’s too late.
