쉐도잉 연습: IELTS listening part 3 Product development presentation: mosquito net - 영상으로 영어 말하기 배우기
레슨 만드는 중...
1
Part 3.
2
You will hear a business studies student called Edward talking to his tutor about some research he is doing on product development.
3
First, you have some time to look at questions 21 to 25.
4
Now listen carefully and answer questions 21 to 25.
5
Hello, Edward.
6
Sit down.
7
Thanks.
8
I need some advice on my presentation about product development.
9
Right.
10
Have you decided what to focus on?
11
Yes.
12
The product I've chosen is a particular type of mosquito net.
13
Any reason for choosing that?
14
Hmm.
15
I spent last summer travelling round Africa with a friend.
16
He's studying medicine, so when we were in a region where mosquitoes cause malaria, we visited a medical centre.
17
I chatted to an administrator while my friend talked to one of the doctors,
18
and I found out they've had far fewer cases of malaria since these mosquito nets became available locally.
19
That made me interested in them.
20
Hmm, OK.
21
Mosquito nets have quite a long history, don't they?
22
I believe they'd been used in Japan for centuries.
23
That's right.
24
Though apparently Queen Cleopatra slept under one in ancient Egypt.
25
That was probably where they were invented.
26
And much later nets were used in China, so perhaps they were invented there independently.
27
Originally they were made of silk, but later cotton was used, and nowadays they're mainly synthetic.
28
It wasn't until the middle of the 20th century that they developed nets treated with insecticides for use by the military, and that was a major step forward.
29
They used an insecticide called DDT, but it was later found that this could be harmful to people as well as mosquitoes.
30
Is that still a problem with modern nets?
31
Oh, no. The chemicals used nowadays are safe, even if people sleep under them every night.
32
And the nets work, and they're odour-free.
33
But they have to be treated fairly often with the chemical, which the owners need to do themselves.
34
Hmm.
35
Presumably distribution of the chemical can be a problem in remote areas?
36
I mean, people may not be able to get hold of it easily.
37
That's right.
38
Hmm.
39
OK, tell me about this net you're going to talk about.
40
Well, the brand name is Olliset, and the product was invented by a Japanese company.
41
These nets are an improvement on the alternatives because the insecticide is contained inside the fibre and released gradually.
42
It's not coated on the outside as with ordinary nets.
43
So the chemicals don't have to be replaced?
44
Right.
45
And Oli-set nets are also tougher and don't tear as easily.
46
They give protection for at least five years compared with a year or two for other nets.
47
Well, it sounds interesting.
48
But for your seminar presentation, will you provide the bigger picture as well?
49
Yes.
50
It'll be a case study of product development.
51
Before you hear the rest of the discussion, you have some time to look at questions 26 to 30.
52
Now listen and answer questions 26 to 30.
53
I thought I'd introduce my presentation by describing the background to the new product, the general context.
54
You mean the business context?
55
Where the investment's coming from and that sort of thing?
56
Well, I was thinking I'd talk first about insect-borne diseases, particularly malaria
57
and why there's such an urgent need for new ways of fighting it.
58
Some people might not know much about it.
59
Yes, that's a good idea.
60
I've got some statistics about the numbers of people worldwide who get the disease each year.
61
I thought I'd show those.
62
They're quite staggering.
63
I can imagine.
64
It's one of the world's biggest health problems, after all.
65
It'd also be useful if you could find some statistical information on how malaria affects countries' economic output and present that too.
66
OK, I'm sure I can find something.
67
After that, I'll talk about mosquito nets.
68
First, the historical development, just briefly, and then I'll introduce the Ollyset mosquito net.
69
Yes, keep it simple.
70
You could just present a bulleted list of its characteristics, the things that make it different from other types of net, and talk that through.
71
Right.
72
Then I thought I'd outline the production process.
73
Fine.
74
Should I give some information about where the money for the project has come from?
75
There are lots of government and private sponsors.
76
Definitely.
77
That's a very important aspect of any product development.
78
Where are the nets being manufactured, by the way?
79
Oh, over half are made in Tanzania by a company called A-Z.
80
They got an interest-free loan to buy in the necessary machinery.
81
Well, I'd say a bit about the company profile as well, and then present figures about numbers of staff and the kinds of people they're employing on the Ollyset project,
82
if you can find the details.
83
Hmm, OK.
84
I haven't included any information about marketing.
85
I've got a lot of notes about it, but I'm not sure how to present them.
86
I wouldn't mention that if I were you.
87
You've only got a short time for your presentation and you've got quite a lot of material here already.
88
But you should provide some figures about output.
89
Have you found out from the company's website how many nets they actually produce?
90
Yes, it's over 30 million a year.
91
Right.
92
Then I'm not sure how to finish off.
93
What do you think about including something on potential...
94
That is the end of part three.
95
You now have 30 seconds to check your answers to part three.
96
Thank you.

이 비디오는 누구를 위한 것인가요?
IELTS 리스닝 파트 3 준비를 하거나, 비즈니스 스터디 관련 대화 실력을 키우고 싶은 중급 이상 학습자에게 완벽한 영상입니다. 특히 제품 개발과 관련된 주제를 다루는 대화에서 나타나는 전문 용어와 논리적인 대화 흐름을 익히고 싶다면, 이 영상을 통해 실제 시험 환경과 유사한 리스닝 연습을 할 수 있어요. shadow speech나 shadow speak를 통해 발음과 리듬을 연습하려는 분들도 이 대화의 자연스러운 흐름에서 큰 도움을 받을 수 있답니다.
빼놓을 수 없는 단어와 표현
영상 속 대화에서 유용한 표현들을 모았어요. mosquito net(모기장), insecticide(살충제), fibre(섬유) 등 제품 개발 관련 전문 용어는 물론, contained inside(안에 포함되어), released gradually(점진적으로 방출된다)와 같은 구문도 실제 의사소통에서 자주 쓰입니다. major step forward(큰 진전)나 bigger picture(전체적인 관점)도 비즈니스 대화에서 필수적인 표현이니 꼭 외워두세요!
발음을 제대로 잡는 방법
이 영상의 화자는 자연스러운 영어 발음을 사용하며, 특히 insecticide와 synthetic와 같은 긴 단어에서 강세를 잘 두고 발음합니다. shadowing site를 이용해 반복 연습할 때는 단어 사이의 연결음(linking)과 강세 위치를 주의깊게 살펴보세요. 예를 들어 "treated with"에서 "t"와 "w"가 연결될 때의 발음을 따라하거나, "Olliset"와 같은 브랜드 이름의 발음을 정확히 익히면, 실제 대화에서 더 자연스러운 발음을 구사할 수 있습니다. 유튜브 영어 공부를 할 때 이런 세부적인 발음 요소를 놓치지 마세요!
shadow speech 연습 팁
- 영상을 5초씩 멈추며 화자의 발음과 리듬을 따라하세요. shadowspeaks처럼 빠르게 따라하지 말고, 정확한 발음을 우선으로 합니다.
- 제품 개발 관련 내용은 논리적인 흐름이 중요하므로, 대화의 구조를 따라가며 말하기 연습을 하면, 말하기의 체계性도 향상됩니다.
- 자주 등장하는 전문 용어는 반복해서 발음해보고, 자신의 말로 재구성해보세요. 이렇게 하면 shadow speak 연습이 더 효과적입니다.
이 영상을 통해 유튜브 영어 공부를 하면, IELTS 리스닝 뿐만 아니라 실제 의사소통 능력도 크게 향상될 거예요. 지금부터 shadowing 연습을 시작해보세요!
이 영상의 문법
화자가 가장 많이 쓰는 문형을 영상 속 실제 표현과 함께 정리했습니다.
| 문형 | 영상 속 표현 |
|---|---|
| 수동태 be + 과거분사 — 누가 하는지보다 무슨 일이 일어나는지에 초점 | were invented · were made · be treated |
| 현재완료 have/has + 과거분사 — 과거의 일이 지금도 관련이 있을 때 | I've chosen · has come · haven't included |
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
