Question:

Why modern people are living longer?Use specific reason and examples to develop your essay.


My answer:


In modern society,people are living longer and longer due to advancement in medical care, sufficient foods provided by highly developed farming technologies.

Advancements in medical care system and techniques elongate people's lives significantly.New medicines are invented and applied to fight against diseases almost every month,some of which are impossible to stand a chance to heal in the past.For example, I read from newspaper last month -scientists in England reported that they have found a new medicine to treat a certain Kidney disease.This advancement could increase the possibility of the patients' survival and would elongate patients' lives by five to ten years.Furthermore,in modern society,people can tremendously benefit from the promotion of medical insurance system launched by government.Take China for instance,with the development of robust economy,more and more farmers in the countryside can join into the medical insurance system which significantly  enhance their abilities to fight against diseases and improve their living quality.

In addition, by applying high techniques in farming, the stability and quantity of the foods are largely increased.In most area of the world, famine ,usually caused shortage of foods, is the first factor that causes people to die in the past fifty years. However, nowadays this situation has been changed significantly by applying  high techniques into farming system,which in turn can improve the foods quality and increase the stability of food provision.For instance,in some poor area in China,in the past, all the farming work was done by the farmer manually,since the government introduced automated mechanical farming system, the efficiency of farming has been improved, resulting in stable provision of food to the resident in the city.

In conclusion,the promotion of medical care system in combination of the stable food provision have contributed to the elongation of people's lives.The former helps to enhance the ability to fight against diseases that have caused death of patient in the past, while the latter prevent people living modern society from famine and starvation.
