現在請仔細聽並回答第21至25題。
5
Hello, Edward.
你好，愛德華。
6
Sit down.
請坐。
7
Thanks.
謝謝。
8
I need some advice on my presentation about product development.
我需要一些關於我產品開發主題簡報的建議。
9
Right.
對。
10
Have you decided what to focus on?
你決定好要專注於什麼了嗎？
11
Yes.
是的。
12
The product I've chosen is a particular type of mosquito net.
我選的產品是一種特定型別的蚊帳。
13
Any reason for choosing that?
選這個是有什麼原因嗎？
14
Hmm.
嗯。
15
I spent last summer travelling round Africa with a friend.
去年夏天我和一個朋友環遊了非洲。
16
He's studying medicine, so when we were in a region where mosquitoes cause malaria, we visited a medical centre.
他正在攻讀醫學專業，所以當我們身處一個蚊子會傳播瘧疾的地區時，我們參觀了一家醫療中心。
17
I chatted to an administrator while my friend talked to one of the doctors,
我和一位行政人員聊了聊，而我的朋友則和其中一位醫生交談。
18
and I found out they've had far fewer cases of malaria since these mosquito nets became available locally.
我發現自從當地開始供應這些蚊帳後，瘧疾的病例數量大幅減少了。
19
That made me interested in them.
那讓我對它們產生了興趣。
20
Hmm, OK.
嗯，好的。
21
Mosquito nets have quite a long history, don't they?
蚊帳的歷史可真夠悠久的，對吧？
22
I believe they'd been used in Japan for centuries.
我相信它們在日本已經被使用了好幾個世紀。
23
That's right.
沒錯。
24
Though apparently Queen Cleopatra slept under one in ancient Egypt.
儘管據說古埃及的克利奧帕特拉女王曾睡在它下面。
25
That was probably where they were invented.
它們很可能就是在那裡被髮明的。
26
And much later nets were used in China, so perhaps they were invented there independently.
很久以後中國也出現了漁網，因此漁網或許是在中國獨立發明的。
27
Originally they were made of silk, but later cotton was used, and nowadays they're mainly synthetic.
它們最初由絲綢製成，後來改用棉花，如今則主要使用合成材料。
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.
直到20世紀中葉，他們才研發出經殺蟲劑處理的軍用蚊帳，這是一項重大的進步。
29
They used an insecticide called DDT, but it was later found that this could be harmful to people as well as mosquitoes.
他們曾使用一種名為DDT的殺蟲劑，但後來發現這種物質不僅對蚊子有害，對人類也可能造成危害。
30
Is that still a problem with modern nets?
現代的網還存在這個問題嗎？
31
Oh, no. The chemicals used nowadays are safe, even if people sleep under them every night.
不會的，現在使用的這些化學物質是安全的，就算人們每晚都睡在它們下面也沒問題。
32
And the nets work, and they're odour-free.
而且這些網好用，還沒有異味。
33
But they have to be treated fairly often with the chemical, which the owners need to do themselves.
但這類裝置需要經常用化學藥劑進行處理，而這項工作必須由裝置所有者自行完成。
34
Hmm.
嗯。
35
Presumably distribution of the chemical can be a problem in remote areas?
想必在偏遠地區，這種化學品的配送可能會是個問題？
36
I mean, people may not be able to get hold of it easily.
我的意思是，人們可能不太容易弄到它。
37
That's right.
沒錯。
38
Hmm.
嗯。
39
OK, tell me about this net you're going to talk about.
好，跟我說說你要講的這個網路吧。
40
Well, the brand name is Olliset, and the product was invented by a Japanese company.
嗯，品牌名稱是Olliset，這款產品是由一家日本公司發明的。
41
These nets are an improvement on the alternatives because the insecticide is contained inside the fibre and released gradually.
這些蚊帳是對現有替代產品的改進，因為殺蟲劑被封存在纖維內部並會逐漸釋放。
42
It's not coated on the outside as with ordinary nets.
它不像普通網那樣在外部有塗層。
43
So the chemicals don't have to be replaced?
所以這些化學藥劑不需要更換嗎？
44
Right.
對。
45
And Oli-set nets are also tougher and don't tear as easily.
而且Oli-set漁網也更結實，不容易撕破。
46
They give protection for at least five years compared with a year or two for other nets.
與其他蚊帳一到兩年的使用壽命相比，這種蚊帳的防護期至少可達五年。
47
Well, it sounds interesting.
嗯，聽起來挺有意思的。
48
But for your seminar presentation, will you provide the bigger picture as well?
不過關於你這次的研討會報告，你會不會也講一下整體的大背景情況？
49
Yes.
是的。
50
It'll be a case study of product development.
這將是一個產品開發的案例研究。
51
Before you hear the rest of the discussion, you have some time to look at questions 26 to 30.
在聽取剩餘討論內容之前，你有一些時間檢視第26至30題。
52
Now listen and answer questions 26 to 30.
現在請聽錄音並回答第26至30題。
53
I thought I'd introduce my presentation by describing the background to the new product, the general context.
我想先介紹一下這款新產品的背景和整體情況，以此作為我演示的開場。
54
You mean the business context?
你是指商務語境嗎？
55
Where the investment's coming from and that sort of thing?
投資資金從何而來之類的問題？
56
Well, I was thinking I'd talk first about insect-borne diseases, particularly malaria
嗯，我想先談談蟲媒傳染病，特別是瘧疾。
57
and why there's such an urgent need for new ways of fighting it.
以及為何我們如此迫切需要找到對抗它的新方法。
58
Some people might not know much about it.
有些人可能對此瞭解不多。
59
Yes, that's a good idea.
對，這是個好主意。
60
I've got some statistics about the numbers of people worldwide who get the disease each year.
我掌握了一些關於全球每年患該疾病人數的統計資料。
61
I thought I'd show those.
我想我該把那些展示一下。
62
They're quite staggering.
它們著實令人震驚。
63
I can imagine.
我能想像。
64
It's one of the world's biggest health problems, after all.
畢竟，這是全球最嚴峻的健康問題之一。
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.

對話背景與情境
這段影片展示了雅思聽力第三部分的典型場景：商科學生愛德華與導師討論他關於“蚊帳產品開發”的研究報告。對話圍繞蚊帳的歷史、改進及實際應用展開，涵蓋了產品研發、跨文化背景等內容，不僅能幫助學習者熟悉雅思聽力的學術討論場景，也是看YouTube學英語的優質素材，適合用於雅思口語練習和日常表達積累。
日常交流高頻短語5則
- get hold of：意為“獲得，找到”。如對話中“人們可能難以輕易獲得殺蟲劑”，可用於表達獲取某物的困難。
- a major step forward：“重大進展”。描述產品升級或技術突破時可用，如“蚊帳新增殺蟲劑是一大進步”。
- compared with：“與……相比”。用於對比事物差異，是口語中常用的邏輯連線短語。
- the bigger picture：“更宏觀的視角”。導師提醒愛德華在報告中涵蓋整體背景，可引申為“全域性觀”。
- case study：“案例研究”。學術討論中常用，指對具體例項的分析，適用於英語口語練習中的話題展開。
分步影子跟讀指南
針對影片中學術對話的特點，採用shadowspeak技巧可有效提升聽力和口語能力：
1. 先完整聽一遍對話，關注整體邏輯（如愛德華選擇蚊帳的原因、產品改進點），建立內容框架。
2. 逐句跟讀，重點模仿連讀（如“travelling round”）和語調（導師提問時的升調），提高英語發音的自然度。
3. 暫停影片，用自己的話複述關鍵資訊（如“Olliset蚊帳的優勢”），強化語言輸出能力。
4. 針對複雜句式（如“直到20世紀中葉才研發出殺蟲劑處理的蚊帳”），拆分結構並反覆練習，提升口語表達的流暢性。
影片中的語法
說話人最常用的結構，並附上影片中的原話：
| 結構 | 影片中的用法 |
|---|---|
| 被動語態 be + 過去分詞 — 強調發生了什麼，而不是誰做的 | were invented · were made · be treated |
| 現在完成時 have/has + 過去分詞 — 過去發生但與現在仍有關聯的事 | Have you decided · I've chosen · they've had |
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
