　　Car and Air Pollution
　　Too many cars have created 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. All the time， they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful， causing disease and even death. 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 the petrol. But it may take decades for the new models of clean cars completely replace the traditional ones. 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. And 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.

　　Fast Food
　　Fast food is becoming more and more popular in China， especially among children and teenagers. Today， nothing is more representative of the fast pace of modern society than fast food. There are several reasons for its popularity. First， it is quick and convenient. Go into a fast food restaurant， and your food will be ready in a minute. You can satisfy your hunger instantly. Precious time won't be wasted in waiting-in-line to order or waiting at your table for your food to arrive. Second， its popularity is also attributed to the clean food， the excellent service and the comfortable environment of the fast food restaurant.
　　However， I think that fast food isn't healthy enough because it does not compose a balanced diet and is low in nutrition. Doctors suggest that people should avoid eating too much fast food. Although home cooking is time-consuming and following washing-u p tiresome， it offers healthy and delicious meals your body likes and needs. Fast food I s only a good choice when you are in a hurry and we should turn to it only once in awhile.
