Script:

Trung: What do you think about the traffic in Ho Chi Minh City, Alisa?

Alisa:Well, honestly, it has a few problems. As an exchange student living here for half a year, I’m not used to travelling in the streets.

Trung: Could you explain it clearly?

Alisa:You know, there are a huge number of vehicles running so fast every minute, so I find it dangerous to go cycling or cross the streets in the rush hour.

Trung: Yes, I also think that traffic congestion here is a complicated problem, especially in the rainy season.

Alisa:I totally agree. Although I can take a bus to school, it usually takes me a lot of time to wait for it, so it’s really uncomfortable to get wet at the bus stop when it rains hard.

Trung: Oh, I see. Do you have any suggestions to solve this issue?

Alisa:It’s hard to say, but I think the city authorities should widen the streets as well as build a modern underground system.

Trung: Couldn't agree more!
