Sit down. 00:00:59,660 Thanks. I need some advice on my presentation about product development. 00:01:04,620 Right. Have you decided what to focus on? 00:01:07,680 Yes. The product I've chosen is a particular type of mosquito net. 00:01:12,040 Any reason for choosing that? 00:01:13,540 Hmm. I spent last summer traveling around Africa with a friend. He's studying medicine, so when we were in a region where mosquitoes cause malaria, we visited a medical center. 00:01:23,960 Mm-hmm. 00:01:24,600 I chatted to an administrator while my friend talked to one of the doctors, and I found out they've had far fewer cases of malaria since these mosquito nets became available locally. That made me interested in them. 00:01:37,500 Hmm, okay. Mosquito nets have quite a long history, don't they? 00:01:42,140 Mm. 00:01:42,640 I believe they've been used in Japan for centuries. 00:01:45,340 That's right. Though apparently, Queen Cleopatra slept under one in ancient Egypt. [laughs] 00:01:50,990 That was probably where they were invented. 00:01:53,060 Right. 00:01:53,540 And much later, nets were used in China, so perhaps they were invented there independently. 00:01:59,020 Mm-hmm. 00:01:59,800 Originally, they were made of silk, but later cotton was used, and nowadays, they're mainly synthetic. 00:02:05,360 Mm. 00:02:06,100 It wasn't until the middle of the twentieth century that they developed nets treated with insecticides for use by the military, and that was a major step forward. They used an insecticide called DDT, but it was later found that this could be harmful to people as well as mosquitoes. 00:02:22,260 Hmm. Is that still a problem with modern nets? 00:02:25,440 Oh, no. The chemicals used nowadays are safe, even if people sleep under them every night. And the nets work, and they're odor-free. But they have to be treated fairly often with the chemical, which the owners need to do themselves. 00:02:39,040 Hmm. Uh, presumably, distribution of the chemical can be a problem in remote areas. I-I mean, people may not be able to get hold of it easily. 00:02:48,180 That's right. 00:02:49,380 Hmm. Okay, tell me about this net you're going to talk about. 00:02:53,500 Hmm. Well, the brand name is Olyset, and the product was invented by a Japanese company. These nets are an improvement on the alternatives because the insecticide is contained inside the fiber and released gradually. It's not coated on the outside as with ordinary nets. 00:03:10,220 So the chemicals don't have to be replaced? 00:03:12,680 Right. And Olyset nets are also tougher and don't tear as easily. They give protection for at least five years, compared with a year or two for other nets. 00:03:22,480 Hmm. Well, it sounds interesting. 00:03:26,329 Hmm. 00:03:26,360 But for your seminar presentation, will you provide the bigger picture as well? 00:03:30,600 Yes. It'll be a case study of product development. 00:03:35,300 Now listen and answer questions twenty-six to thirty. 00:03:42,420 I thought I'd introduce my presentation by describing the background to the new product, uh, the general context. 00:03:49,140 You mean the business context? Where the investment's coming from and that sort of thing? 00:03:54,300 Hmm. Well, I was thinking I'd talk first about insect-borne diseases, particularly malaria, and why there's such an urgent need for new ways of fighting it. Some people might not know much about it. 00:04:05,900 Yes, that's a good idea. 00:04:07,660 I've got some statistics about the numbers of people worldwide who get the disease each year. I thought I'd show those. Hmm, they're quite staggering. 00:04:15,960 I can imagine. It's one of the world's biggest health problems after all. It'd also be useful if you could find some statistical information on how malaria affects countries' economic output and present that too. 00:04:30,760 Hmm, okay. I'm sure I can find something. After that, I'll talk about mosquito nets. First, the historical development, just briefly, and then I'll introduce the Olyset mosquito net. 00:04:42,840 Hmm. Yes. Keep it simple. You could just present a bulleted list of its characteristics, the things that make it different from other types of net- 00:04:51,240 Mm. 00:04:51,250 -and talk that through. 00:04:52,460 Right. Then I thought I'd outline the production process. 00:04:55,800 Fine. 00:04:56,740 Should I give some information about where the money for the project has come from? There are lots of government and private sponsors. 00:05:03,500 Hmm, definitely. That's a very important aspect of any product development. Where are the nets being manufactured, by the way? 00:05:11,020 Oh, over half are made in Tanzania by a company called A to Z. They got an interest-free loan to buy in the necessary machinery. 00:05:19,360 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 Olyset project, if you can find the details. 00:05:30,620 Hmm, okay. I haven't included any information about marketing. I've got a lot of notes about it, but I'm not sure how to present them. 00:05:38,900 Hmm. I wouldn't mention that if I were you. You've only got a short time for your presentation, and you've got quite a lot of material here already. But you should provide some figures about output. Have you found out from the company's website how many nets they actually produce? 00:05:54,980 Yes. It's over thirty million a year. 00:05:57,260 Hmm, right. 00:05:58,620 Then I'm not sure how to finish off. What do you think about including something on potential invest- 00:06:07,469 That is the end of part three. You now have thirty seconds to check your answers to part three. ## 题目与答案 ### 21. 21 Edward heard about a type of mosquito net from 21 Edward heard about a type of mosquito net from - an administrator - a doctor - a friend **答案**：an administrator 原文定位：I chatted to an administrator while my friend talked to one of the doctors, and I found out they've had far fewer cases of malaria since these mosquito nets became available locally 同义替换：「heard about」↔「found out」 ### 22. 22 Edward believes that mosquito nets were first used in 22 Edward believes that mosquito nets were first used in - China - Japan - Egypt **答案**：Egypt 原文定位：I believe they've been used in Japan for centuries;That's right.
