(The following is a sample essay response tailored to Vietnamese students learning English.) The city of Hanoi is facing many problems nowadays. One of the major concerns is the traffic congestion. With the increasing number of vehicles on the road, the city's infrastructure is unable to handle the demand. As a result, commuters often spend hours stuck in traffic, wasting time and fuel. To address this issue, the city can invest in public transportation systems such as buses and metro lines. This will encourage people to leave their private vehicles at home and use public transport instead. Additionally, the city can also implement car-sharing schemes, where people can share rides with others going in the same direction. Another pressing problem is the pollution in the city. With the rapid industrialization and urbanization, the city is facing severe environmental degradation. The air quality is poor, and the waterways are polluted. To combat this, the city can implement stricter regulations on industries to reduce their carbon footprint. The government can also launch campaigns to raise awareness about the importance of environmental conservation and encourage citizens to participate in clean-up drives. Furthermore, the city can also focus on creating more green spaces. By building parks and gardens, the city can not only improve the air quality but also provide citizens with recreational areas. This can be achieved by converting abandoned or underutilized spaces into green zones. Lastly, the city can also address the issue of waste management. By implementing a proper waste collection and disposal system, the city can reduce the amount of waste that ends up in landfills and oceans. The government can also encourage citizens to adopt sustainable practices such as recycling and composting. In conclusion, the city of Hanoi is facing numerous challenges, but with the right solutions and a collaborative effort from citizens and the government, these problems can be addressed. By investing in public transportation, reducing pollution, creating green spaces, and improving waste management, the city can become a cleaner, greener, and more livable place for its citizens.
