首段：改写题目

The bar char reveals that the population was witnessed and the table displays the average ages of people in three countries in 1995,2000 and 2025.

第二段：图一

As can be seen from the bar chart，the population with approximately 400 million in 1950 increased significantly to 1100 million in 2000，reaching an astonishing over 1400 million in China in 2025. In contrast，the population of US is much less than that of China，which is that the number with roughly 200 million was almost similar in the United States in 1950 and in 2000 but it is projected that the change will soar to 760 million people in 2025. Obviously，the smallest population of Spain was seen among three countries，whose number by 200 million indicates the changes between the growth and the decline over a span of 100 years from 1950 to 2050.

第三段：图二

According to the table，the average ages of people in China and Spain illustrate a substantial rise during 1950 and 2050  when the lowest with 65 and 70 years in 1950 experience an upward trend with 83 and 77 years in 2050 respectively. However，73 years of the average ages in 1950 grew slightly by 2 years in 2000 and then the decrease will be demonstrated at 74 years in the United States in 2050.

结尾段：总结概括（对比不比较）--写出最明显或最突出的地方【不能再有数据出现】

To sum up，not only does the trend of population in general ascend，but also the senior citizens will be a considerably large and have a shrinking number of young people in China，US and Spain from 1950 to 2000 and even the foretelling of 2050.
