　　[例子]The graph below shows the changes of consumer price index in a certain country from the year 1929 to 1975. Write a short composition of about 120 words to describe the changes and offer your own reasons for the changes.

　　[范文]This graph gives information about the changes in consumer price index from the year 1929 to 1975. After studying the information in the graph we may conclude that prices increased greatly over the time span despite fluctuations. Although the consumer price index reached its bottom in 1933, the index almost tripled from 1929 to 1975, growing from 50 to 150.

　　The most possible reason for the rise of prices was economic development. As is known by everyone, when one economy becomes prosperous, it usually needs a larger amount of circulating money. And since the overall economic development of most countries between 1929 and 1977, including the country in question, was for the better, it was understandable that more and more bank notes had been added to circulation, and this almost inevitably caused inflation, which brought about the rise in prices.
