　　擁有私家車

　　as we can learn from the graph, the ownership of private cars varies from year to year. in the year of 1990, there are only two cars among 100 families, but in the year of 1995, it is 10, and it goes up dramatically to 30 in 2000. generally speaking, it involves an upward trend.

　　there are three reasons for the change. to begin with, peoples income has been improved, more and more families can afford cars; in addition to it, the price of cars has been brought down sharply; last but not the least, various measures to stimulate consumption taken by our government cant be ignored. all these factors result in the rapid change in the ownership of private cars.

　　to sum up, with the further development of our economy, there is no doubt that more and more families will have their own cars.
