发展中国家的保健(Health Gains in Developing Countries)

　　Remember to write it neatly

　　A study in 1991 showed that the life expectancy had increased and the infant mortality had decreased in developing countries since 1960.

　　As you may see from the diagram, the life expectancy in 1960 was 40 years old and it was about 60 in 1990. And we can see from the diagram, the infant mortality was about 200 deaths per 1,000 births in 1960, and it was approximately just below 100 in 1990.

　　The reasons that mused changes are diverse. On the one hand, the medical service is better than before. The new statistical data show that a good doctor can save 1,000 peo ple's lives in his whole life. And in developing couuntries more and more good doctors are heginning to serve the people. On the other hand, our foods are much better than before. A social investigation shows that people spend more mid more money on food instead of on clothing. That helps to make our bodies stronger.

　　From all the faet given above,we can see that developing countrles are becoming better and better, and people can gain health in developing countries.
