　　The bar chart below shows the tendencies of infant mortality and people’s life expectancy in a developing country. Look at the graph and write a composition of about 120 words making reference to the following points.

　　1. The changing tendencies in infant mortality and life expectancy.

　　2. Possible reasons for the changes.

　　[范文]These two graphs describe respectively the development tendency of infant mortality and life expectancy in a developing country. As is show in the graphs, there has been a marked decrease in the infant mortality rate between the year 1960 and 1990, whereas the life expectancy zoomed from 40 in the year 1960 to 90 years in 1990. In the year 1960, the infant mortality rate was about 225 in 1000, as compared to about 100 in the year 1990.

　　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.
