Changes in the Ownership of Houses
第一段：描写图表段
According to the chart，we can see clearly that in the past decade the ownership of houses in this city has changed greatly.In 1995，the proportion of state-owned houses is far higher than that of private houses，taking up respectively 75%and 25%.However，5 years later，the proportion of private-owned houses rose to 40%，and by 2000，it has reached 80%.It is obvious that more and more individuals have owned their private houses.
第二段：说明原因段
The following three reasons can account for the rapid growth of private housing ownership.Firstly，state subsidies for public housing are gradually eliminated.That is to say，without the housing subsidy，people are encouraged to buy their own private houses.Secondly，with the rapid development of economy，people’s income has risen significantly.Thirdly，various forms of mortgage loans with reasonable interest permit people to improve their housing condition in advance.As a result，people gradually have a strong desire to own a house of their own.
第三段：说明影响段
The change of the ownership of houses exerts a positive influence on the society.For one thing，this market-driven housing policy can lead to better resource allocation.For another，since more and more citizens are using mortgage and installments to buy their apartments，they form a new industry，broad the business of banks，and promote the whole economy.
