I once visited a city where the air was not very clean. The sky was not blue, but instead, it looked a bit gray. There was a lot of dust and tiny particles in the air, making it difficult to see far away.

I could feel the pollution in the air, and it made me cough a little. The smell was not fresh like in a park, but more like something not very pleasant. People were wearing masks to protect themselves from breathing in the dirty air.

It was a bit sad because I like places with clean air, and I could tell that the pollution was not good for the environment. I hope that in the future, we can find ways to make the air cleaner for everyone to enjoy.

Vậy chủ đề là gì vậy bạn?

- urban sprawl       - air pollution

- noise                   - bad weather

- high cost of living -crime

- traffic jams           overcrowding

    Traffic congestion is the biggest problem in our city. As the number of private cars has increased recently, the city is becoming full of vehicles. . Congestion has many consequences including wasting people's time, frustrating them and seriously affecting the air, leading to reduced work quality and reduced labor productivity. So what can we do to solve this problem. First, the government should complete the transport system quickly to accommodate the increase in the number of cars and motorbikes. The public transport system needs to be upgraded to meet the needs of students, the elderly and low-income people. In short, congestion is a big problem, affecting people's lives, but this problem needs to be solved in the long run.
