【答案解析】These two graphs describe respectively the development tendency of infant mortality and life expectancy in a developing country. As is shown in the graphs, there has been a marked decrease in the infant mortality rate between the year 1959 and 2012, whereas the life expectancy zoomed from 130 in the year 1959 to 250 in 2012. In the year 1959, the infant mortality rate was about 200 in 1000, as compared to about 50 in the year 2012.
There are multiple reasons for the decrease in infant mortality rate, the most important of which, I would propose, is the development of medical care for children and expecting mothers. The increase in life expectancy is due to several reasons. Better chances for personal development, better education and better economic environment which the development of the country has provided are all contributing factors, in addition to the development of medicine, which greatly reduced the chances of dying from diseases.
On the basis of the analysis above, it is safe to conclude that certain exciting changes have taken place in this country. I believe that this trend will be going on for a better direction.
