IELTS 리스닝 섹션 1 연습 문제

Tutor: So, Lewis, let's hear what you're doing for your next project.

Lewis: I've decided to design a rain garden for Highfield Primary School.

Tutor: A rain garden. Is that the school you mentioned before?

Lewis: Yes. My mother teaches there, so I know the site quite well. They have a persistent problem with water collecting on the playground after heavy rain, especially along the main route to the dining hall.

Tutor: So the garden would help manage the surface water?

Lewis: Exactly. It would also provide an outdoor teaching space, which the science staff are very keen on.

Tutor: Okay. If the school is your client, what might make them hesitate?

Lewis: I first assumed the building cost would be the main thing they worried about. But in this case the parent teacher association has already been raising money for an outdoor project, so the cost of construction is not the problem I need to focus on.

Tutor: What about disruption while it is being installed?

Lewis: I checked that with the head teacher. If the work is done during the summer holiday, there is a six week period when the playground is clear, so installation time should be manageable. However, the groundskeeper already manages two school sites, and he is not going to welcome another planted area that needs weeding and checking.

Tutor: A fair point. A rain garden can fail quite quickly.

Lewis: So, my idea is to involve the school eco club. They meet weekly with the science teacher, and they already do things like composting and feeding birds.

Tutor: Right.

Lewis: [hesitant] Yes, with adults handling any heavy work. I am still not sure about the location though. The garden would sit beside the main path between the classrooms and the playground, and at break time hundreds of children use that route.

Tutor: [sighs] Hmm.

Lewis: If they walk through it, they will compact the soil, and then the drainage function is lost. I am thinking of a low timber edge, enough to show the boundary without making it look defensive.

Tutor: That sounds sensible. And the depth of the planting bed?

Lewis: That is covered by the sustainable drainage guidance, so I do not think it will be controversial.

Tutor: Good. Have you also looked into recent developments in rain garden construction?

Lewis: I have, though I am still separating genuine developments from things that are just being advertised as new.

Tutor: What have you found so far?

Lewis: Native seed mixes are mentioned in a lot of brochures.

Tutor: Useful, but not really recent. Those mixes have been standard for years.

Lewis: I wondered about rubberised edging strips too.

Tutor: They are being promoted, but for this project ordinary timber would do the job perfectly well. I would not present rubber edging as a significant development.

Lewis: I found a case study using an overflow regulator valve as well. Should I include that?

Tutor: Mention it if you need to, but it is conventional technology. It is important, but I would not highlight it as new.

Lewis: There is also this modular gravel sleeve I have been reading about. Instead of filling a trench with loose gravel and levelling it by hand, you put in a sleeve already packed to the correct depth.

Tutor: That is worth mentioning. It speeds up construction and gives a more even drainage layer.

Lewis: I was also looking at soil moisture monitoring sensors. Small probes buried in the planting layer can send readings to a tablet, so the school would know when the soil is too dry or too wet.

Tutor: That is a much better educational link for the science staff.

Lewis: And it would help maintenance too, because staff could respond before the plants begin to fail.

Tutor: Good. Just be careful to distinguish those from older standard practices when you write it up. Now, you said you had a section drawing?

Lewis: I do. It is rough, but it shows the wall on the left, the planted depression in the middle, and the drainage outlet on the right.

Tutor: Good. Let's talk through it. First, where does the rainwater enter the garden?

Lewis: It comes from the roof downpipe beside the building wall. From there it runs through the short sloping inlet channel on the left, just above ground level, before reaching the planted depression.

Tutor: And the strip along the front edge?

Lewis: That is the low timber kerb. It sits between the path and the planted depression, so it marks the edge without making the area feel fenced off.

Tutor: Under the planted area I can see a grey layer.

Lewis: That is the pre formed gravel sleeve. It is below the soil and spreads the water evenly through the base of the garden.

Tutor: So the brown layer above that is the growing medium?

Lewis: Yes, that is the soil layer where the seed mix and the plants would go.

Tutor: There is also a small object in the soil with a line running back to the box.

Lewis: That is the monitoring sensor. The probe is buried in the soil, and its cable runs to the maintenance box on the surface.

Tutor: And what happens during a heavy storm if the garden fills up?

Lewis: Excess water leaves through the overflow pipe on the right hand side. That pipe takes water back into the surface drainage system so the path does not flood.

Tutor: Good. I think the section is much clearer now. Next week I would like proper references and a costed schedule.

Lewis: I thought you might say that.

Tutor: [laughing] Good. Then I am becoming predictable.

Lewis: [laughing] Only in a useful way.
