英语四级高分作文：发展中的国家
It can be seen from the chart that there have been dramatic changes in lifeexpectancy and infant mortality in developing countries in the past decades. As
the chart shows, people’s life expectancy soared from 40 years old to 60 years
old from 1960 to 1990. Meanwhile, infant mortality declined from 200 to 150
deaths per thousand births.
The change in the chart may be attributed to a number of factors, but the
following are the most critical ones. First, developing countries’ economy has
been developing at a considerably high speed in the past decades. Therefore,
people have more extra money to improve their health. Secondly, the advances in
medical sciences and boom of medical industry provide citizens with more
opportunities to cure their diseases. Last but not least, people have attached
greater importance to their quality of life, thus they have spent more money and
time to build up their bodies.
In a word, this chart is a perfect indicator of developing nations’ fast
expanding economy and people’s rising standard of life. Although a series of
problems have arisen in the process, it is reasonable for us to believe that
they can be solved in the near future with effective measures taken by both the
government and the public.
(或If this trend continues, developing countries will soon approach the
developed countries in terms of health care. People will live longer and
healthier lives. The result of this will be happier and more productive
populations
