describe a change that will improve your local area.
you should say:
what the change is,
how the change works,
what kinds of problems the change will solve,
and how you feel about the change.
the change i want to talk about today is to plant more trees to improve the environment in the local area. on the one hand, the government should increase the budget on the environmental protection（增加在环境保护方面的预算）, in which case more workers can be employed to plant more trees on both sides of the road; on the other hand, the teacher should teach our younger generation that it is every citizen’s obligation（每一位公民的义务）to protect the environment. as far as i am concerned, this change will help to solve many problems. firstly, the air will be purified(空气将会被净化). trees are beneficial to the environment, since they absorb the carbon dioxide（吸收二氧化碳） and give off the oxygen（释放氧气）. in today’s society, the pollution is becoming even more serious, so it is the government’s top priority（当务之急） to encourage more people to plant trees in order to purify the air as well as to protect our common home. secondly, the change will preserve the soil and the water（保持水土） in my hometown. my hometown is located in the north-western part of china, which has serious desertification problem（严重的荒漠化问题）. in this case, planting more trees can improve the environment of the city as well as prevent the soil erosion（预防水土流失）. as for my feelings about the change, firstly, i have to say, this change will definitely improve the air quality as well as strengthen citizens’ sense of environmental protection（增强市民的环保意识）. secondly, it will set a good example to the rest of the country, and even to the rest of the world. i think there will be an increasingly number of people to join in the team of alleviating the pollution（缓解污染问题） as well as protecting the earth. based on the reasons mentioned above, i think this improvement is really beneficial to the local area.
