4、o the problem of poverty? Why or why not?Food aid is a short-term solution, as it gives food immediately to people who are very hungry, but it does not provide them food for the future.What does this picture show?This picture shows vegetables growing in a greenhouse.What do you think of growing vege

7、ed into towns or cities.Do you prefer living in the city or in the country? Why?What problems may rapid development cause?Rapid development can harm the natural environment.

What will it look like in twenty years time?In my opinion, compared to the old city several years ago, my home town, Nanjing, is developing at a fast rate and is taking on
11、 a new look. As the capital city of east Chinas Jiangsu Province, Nanjing has experienced great changes. Many buildings and motorways have been built, polluted rivers have been cleaned, and more trees and flowers have been planted. With the continued development of the city, there is no doubt that i
12、t will develop into a modern, international city in twenty years time. 2. Do you think that giving food and money to poor people will solve all their problems? Why or why not?I do not think giving food and money to poor people will solve all their problems. Food aid is merely a short-term solution t
13、o a long-term problem. Giving food and money will solve the immediate problem of hunger and food shortages, yet the problem will still exist after the food has been eaten and the money has been used up. There are many causes of poverty. In order to solve the problem, we need to identify what causes
14、poverty and then try to combat it.As I see it, development brings both opportunities and challenges. Without correct policies and strategies, it may be bad for a country. To begin with, it might do harm to our natural environment. For example, many trees have been cut down in order to build factories, roads and bridges. Natural resources may also be used up in development. Do you think that development may be bad for a country in some ways? Why or why not?
