🎙️ Now it's time for your 2-minute talk!
Describe a place in a city where you go to cool down or to relax in hot weather.
You should say:
- where it is
- how you get there
- what you do there
and explain why it feels cooler or calmer than other places.
Record your response (90–120 seconds):
[Bài tập luyện nói]
Well, to be honest, whenever summer gets sweltering in the city, there's one small public courtyard near my apartment that I always head to. It's tucked away behind an old library, just a short walk from my place, so I usually just stroll over on foot.
When I get there, um, I usually find a shaded wooden bench near the central fountain. I like to sit under the big trees, listen to the trickling water, and sip on an iced tea while reading a book or just relaxing.
The main reason it feels so much calmer than the rest of the neighborhood is all the greenery. The surrounding concrete streets get really hot, but this spot has thick moss, leafy trees, and water features that keep the area cool. It really feels like a breath of fresh air when the rest of the city gets stuffy and warm. I'd much rather rest there than stay inside with the aircon running all afternoon.
Useful Phrases & Plain Notes:
- head to: go to a place. A very common way to say it.
- tucked away: hidden in a quiet spot.
- so much calmer than: a natural way to compare two places.
- a breath of fresh air: something that feels fresh and pleasant.
💬 Let's discuss deeper urban weather questions!
Do you think air conditioning is the best way to deal with hot weather in a city?
Record your spoken answer:
[Bài tập luyện nói]
Well, to be honest, I don't think it's the best way. Aircon gives quick relief indoors, but, um, in my flat it's noisy and the bill is always high. In my view, relying only on aircon is just a quick fix. Cities should look at long-term ideas too, like planting trees and building green roofs. For me, a shady street feels much nicer than a cold room. That way, we can cool down whole neighborhoods naturally instead of just hiding inside with the fan on.
Useful Phrases & Plain Notes:
- In my view: a common way to give your opinion.
- a quick fix: a fast answer that does not solve the real problem.
- cool down: become cooler, or make a place cooler.
Who should pay for plants and trees in a city, the council or the people who live there?
Record your spoken answer:
[Bài tập luyện nói]
Personally, I'd say the council should pay for most of it, because everyone uses the parks and trees. After all, a tree on my street makes everyone's walk home nicer. However, um, residents can play a part too, for example by looking after small plants near their own apartments. So, in my opinion, it works best as a shared job. The council can pay for the big parks, while residents help out with everyday care for the places near their homes.
Useful Phrases & Plain Notes:
- play a part: take an active role in something.
- in my opinion: a simple way to say what you think.
- help out: give some help. A simple everyday phrase.
How might cities look different in thirty years if summers get hotter?
Record your spoken answer:
[Bài tập luyện nói]
If summer temperatures keep rising, I reckon our cities will look quite different. For one thing, we'll probably see far more green roofs and gardens on tall buildings instead of plain concrete. Um, architects might also design narrower streets to make shade, or build covers over the walkways. I've always felt that cities will have to adapt to the weather, so adding more plants will just become normal. Overall, I think cities will look much greener, and people will spend more time outside in the evenings.
Useful Phrases & Plain Notes:
- I reckon: a casual way to say I think.
- for one thing: a natural way to give your first reason.
- adapt to: change so that you can live with new conditions.
Would you like a garden on the roof of the building where you live? Why, or why not?
Record your spoken answer:
[Bài tập luyện nói]
Oh, absolutely! I'd love to have a rooftop garden in my building. For me, it would be a fantastic place to unwind after work and get some fresh air without traveling to a distant park. Plus, on hot summer days, having soil and plants right above us would help keep the top floors cool, which is a huge bonus. Um, it would also be great for chatting with neighbors. So yeah, I've always felt that rooftop gardens make city apartment living much more enjoyable and peaceful.
Useful Phrases & Plain Notes:
- unwind after work: relax after a busy day.
- a huge bonus: a very good extra thing.
- I've always felt: a natural way to start a personal opinion.
