Wow, nice work!  Very good English!  One mistake you made consistently was on "rural area/urban area."  When you are speaking generally, you use the plural:  

"Rural areas are more peaceful" or "This will improve urban areas"

When you are talking about a specific place, it may be singular:  

"I am from an urban area." or "The building was in a rural area."

But really you are doing good work!  

IELTS writing task 2. New technologies or free education?

Improving the quality of life for people in developing countries is a crucial social issue.  
It is a crucial social issue in terms of how to improve the life quality of people who are living in developing countries. Some scientists suggest that governments should import new technologies while some educators educationalists believe reckon that providing free education for the public is should be a better way. I personally tend to agree that both advice sounds reasonable but the former one seems to be more viable and practical. ("advice" cannot be plural.  "both sides' advice sounds reasonable" or "both positions sound reasonable")

People’s daily life invariably benefits from new technologies. For example, governments could import modern public transport systems like urban rail transit and rapid bus transit to provide cheaper and more comfortable seats for city commuters, and thus tackle traffic jams in the urban areas. For those who live are living in rural areas area, the local communities and governments may introduce modern agricultural techniques such as fertilizers and irrigation systems to help farmers produce much more crops and grains. This would contribute to reducing the living cost in the rural areas area. In addition, new clean and sustainable energy technologies like nuclear energy and solar energy should be adopted to reduce the consumption of coal and petroleum, serving to solve the increasingly growingly severe air pollution problems in developing countries.

Providing free education for the public would also help. One can expect that Expectedly, an individual who has been well trained and holds a higher degree would have more chance to find a better job. However, given the limited budget in developing countries, this policy seems to be less realistic.

In conclusion, although free education for the public seems to be useful to improve the literacy level in developing countries, innovative (spelling!) innoviative technologies could directly prompt the development of developing in cities and rural countries, which would increase the people's life quality of people.(281 words)
