Nam: Hi, Mark!
Mark: Hi, Nam! Sorry I'm late. I got lost because your neighbourhood has changed a lot.
Nam: Yeah. It's been three years since your last visit. Anyway, do you want to go for a walk? I'll show you around.
Mark: Fresh air and a walk sound nice. Let's go!
Mark: Nam, there used to be a rice field opposite your house, right?
Nam: Exactly, Mark. But now they have built several high-rise buildings. The city is getting bigger and bigger.
Mark: Yes, more and more people want to live in urban areas nowadays. This is part of the process of urbanisation.
Nam: That's true. There are also new public parks and people can enjoy more leisure activities. In addition to the big shopping centre, there is a convenience store on every corner. And look at our new electric buses! Do you want to go for a ride?
Mark: Sure, Nam... Wow! The bus is so quiet and comfortable! It's the first time I've been on an electric bus. Getting around is probably becoming more and more convenient for local residents.
Nam: Not really. The more crowded the area becomes, the worse traffic jams get, especially during rush hour. The cost of living is also going up. These are the changes that I don't like.
Mark: That's true, Nam. I guess urbanisation can also cause problems.
