I hope this is helpful,Please help me to correct my essay. Thanks very much in advance.
In general, people are living longer now. Discuss the cause of this phenomenon. Use specific reasons and details to develop your essay.
People in the world are now living much longer. For example, in Japan the average life expectancy now 86.05 years for women and 79.29 years for men. The number is much greater than that of the last few years. [Do you have any support for this statement?]
One of the causes
that life expectancy is increasingof increased life expectancy is theagricultural. In the past, many people starved to death. They didn't have enough to eat, but now with the development of technology, there is more and more food, therefore that means there arefar fewer people die of hunger. [Here is a good place to give at least one example of the technological advances you cite as a cause.] Take people in my country, Vietnam, for instance. In 1945, there weretwo million people starved to death. However, nowadays the number of people dying of hunger is much lower. [Support? Do you have a number?]
Another cause is that people know better what affects health. For instance, they know that taking exercise
sis good for them. A national campaign called "Exercise is Medicine" was recently held in the United States to educate doctors and their patients on the importance of regular physical activity for preventing disease and increasing longevity. Since then, more and more people take exercise everyday to stay more active and healthier. [Again, do you have any supporting evidence for this statement?]
also theof most importance [or, 'most important'], is the evolution of medical science.
A lot of new chemicals ['chemicals' or treatments or medicines?] are now discovered. The technology is improved so there are machines that cure disease such as cancer, which used to result almost inevitably in death. [For every statement you make in an essay like this, you must provide some support. What chemicals? What technologies? What are the statistics on cancer death rates?]
In conclusion, improvement in agriculture, increasing awareness in healthy living and advancement in medicine are key factors
to have athat result in longer lives. In the coming years, we may hope to see an even greater increase in life expectancy.
