Health Gains in Developing Countries
From the graph we can see the health gains in developing cotmtries. In l960, the average life span or life expectancy was only 40 years old. In 1990, after thirty years, the life expectancy rose to 60. At the same time, with the life expectancy going up, the infant mortality is coming down. In 1960 the infant mortality was 200 deaths per 1000 births. That is, about 200 infants died at birth among 1000 babies born. In 1990, the infant mortality declined to 100 deaths per 1000 births.
What are the reasons for this situation? I think it lies in three respects. First, economy is developing as time progresses. People am better off than before. Second, education plays an important role. People are better educated and more civilized. They are more aware that good health ensures success in life and work, Third, the government pays more attention to the protection of the environment. More measures are being taken to deal with the problem of pollution. That is why life expectancy is on the rise and infant mortality on the decline.
发展中国家健康状况上升
从表中可以看出，发展中国家健康状况正在上升。1960年，平均寿命或期望寿命仅为40岁。30年后的1990年，增长到60岁。同时，随着期望寿命的增长，婴儿死亡率下降了。1960年的娶儿死亡率为千分之二百，就是说，在l000个新生儿中有200个死亡。1990年的婴儿死亡率已降到千分之一百。
这种状况说明了什么?我认为有3个方面。首先，随着时间的推移，经济在发展，人民比以前富裕了。其次，教育起着重要的作用。人民受到更好的教育，更文明，意识到良好的健康状况是生活、工作成功的保证。第三，政府更加重视保护环境，采取更多措施治理污染问题。这就是期望寿命上升、婴儿死亡率下降的原因。
