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 20xx. Generally speaking, it involves an upward trend.
There are three reasons for the change. To begin with, people’s 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 can’t 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.
我們可以從圖中得知，私家車的所有權每年都在變化。在1990年，有100間家庭只有兩輛車，但在1995年，它是10，它在20xx年會大幅上升至30。一般來說，它處於一個上升的趨勢。
這個改變有三個原因。首先，人們的收入得到了提高，越來越多的家庭能夠買得起汽車;另外，汽車的價格大幅下降;最後但並非最不重要的，我們政府採取的各種刺激消費的措施是不容忽視的。所有這些因素導致私家車的所有權的快速變化。
綜上所述，隨著我國經濟的進一步發展，越來越多的家庭將擁有自己的汽車，這是毫無疑問的。
