Shadowing Practice: IELTS listening part 3 Product development presentation: mosquito net - Learn English Speaking with Video

Ders oluşturuluyor...
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.

  3. Kendinizi kaydedin ve orijinaliyle karşılaştırın; mosquito, malaria, insecticide gibi kelimelere özellikle dikkat edin.

Gölgeleme Tekniği Nedir?

Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
