• Discuss Kelly's viewpoint on prioritizing essential services like hospitals Body Paragraph 2

• Discuss Claire's viewpoint on incorporating green spaces into existing structures Conclusion

• Summarize your opinion considering both perspectives

5. Grammar

I believe that a city needs the foundations to create a society that is convenient for people whilst keeping their health scales up. To accomplish this, there will be some problems that we need to sort out, and some infrastructure that we need to input.

Talking about convenience, lots of green spaces inside a crowded living area may not be that efficient for the citizens, because most of the time, people are more willing to go to a supermarket rather than a park at the same distance because they need the supermarket to provide them with goods to replenish themselves and intake nutrients, while a park cannot eliminate their hunger. This shows that convenience-wise, a park is not the best choice for taking up the urban space that we need to use for more important infrastructure.

For the health of the citizens, a hospital is needed, but it can be located a bit far away from the urban areas, because even if there is an emergency, ambulances can quickly fetch the patient and make sure that he or she will have enough time to be saved. However, if people want to exercise and keep up their health scales by themselves, a park is a very good choice. It can help prevent some diseases and elevate fitness of the whole community. So through this comparison, we have come to a conclusion that a park can work more for people's health rates rather than a hospital, which can still function well even if it is not in the center of the urban area where people live.

Display title: 6 Revised Essay

Balancing urban development with the well-being of citizens is a crucial aspect of city planning. In order to achieve this, it is essential to address various challenges and prioritize the necessary infrastructure.

In terms of convenience, allocating large amounts of green space within densely populated areas may not be the most efficient use of limited urban land. Often, people prioritize visiting supermarkets over parks due to their immediate needs for sustenance and essential goods. Supermarkets contribute significantly to the daily lives of citizens by providing them with necessary resources. Consequently, it is evident that in terms of practicality, urban spaces should prioritize essential infrastructure over recreational areas such as parks.

However, when considering public health, green spaces can play a vital role in promoting overall well-being and fitness within communities. Parks provide an accessible space for exercise and leisure activities that can help prevent certain diseases and improve the quality of life for residents. In contrast, hospitals are undoubtedly crucial for addressing medical emergencies but do not necessarily need to be located within the heart of urban areas. With efficient emergency services such as ambulances, patients can still receive timely care even if hospitals are situated at a distance from residential zones.

In conclusion, while parks contribute positively to public health, it is essential to strike a balance between providing necessary infrastructure and recreational spaces in urban areas. Allocating land for essential services like supermarkets should take precedence over creating green spaces; however, incorporating innovative solutions such as rooftop gardens or integrating greenery into new building designs can help ensure that both aspects are adequately addressed in city planning.

Title: 6 文章修订

I concur with Claire's perspective on creatively utilizing limited urban space to establish green areas without hindering the construction of essential facilities.

To illustrate this point, I would like to mention Singapore as an exemplary case. Despite being a relatively small city-state in Southeast Asia, it has experienced rapid urbanization, leading to the construction of numerous high-rise buildings and skyscrapers. Simultaneously, Singapore has earned the reputation of being a garden city. Urban planners have ingeniously capitalized on every possible location for greenery, such as street corner gardens, along highways, and atop buildings. Presently, Singapore is not only one of the most developed countries globally but also one of the most eco-friendly nations. This achievement demonstrates that urban green spaces and facility construction can coexist and progress simultaneously. (130 words)

I disagree with Kelly and Claire, and I insist using a piece of available land as a green space is useful both for people's mental health and the beauty of the city. To begin with, a beautiful park is a good place for people to relax and connect to the nature. If people want to keep mental healthy, they need some places for them to enjoy the quiet and beauty of the nature and forget the problems and pressure in their lives. Especially for the people with children, green space could create a good environment for these families to have fun. With these green spaces and the good experience made there, people may have less need to the hospitals.

I respectfully disagree with both Kelly and Claire, as I firmly believe that allocating available land for green spaces is highly beneficial for individuals' mental well-being and the overall aesthetic appeal of urban areas. Firstly, well-designed parks provide a serene environment for people to unwind and reconnect with nature. To maintain optimal mental health, individuals require tranquil spaces where they can momentarily escape life's stressors and pressures. This is particularly important for families with children, as green spaces offer an ideal setting for leisure activities and bonding experiences. Consequently, the availability of such spaces may reduce the need for medical interventions related to stress-induced ailments. Furthermore, expansive parks significantly enhance a city's visual appeal, an effect that cannot be replicated merely by incorporating small patches of greenery within urban landscapes. (134 words)

It is undeniable that transforming available land into shopping centers or manufacturing plants can yield significant economic benefits. However, I contend that designating such spaces for green areas, replete with trees and plants, would be a more advantageous choice.
