Thanks for coming around. 00:01:05,640 Hi, Fran. No problem. We need to try and get this presentation finished. 00:01:10,480 Mark, let's start with the way dolphins make sounds. 00:01:14,060 Well, we all know that dolphins make clicking noises to communicate. 00:01:17,940 Yes. They have tongues and larynxes as humans do, but what's really strange about the dolphin is that the sounds are focused through an extraordinary organ called the melon, which most other sea mammals don't have. 00:01:31,440 So shall I take over from there and speak about the different dolphin types? 00:01:36,780 I want to share what we found out about those rare dolphins that are special just to New Zealand in particular. 00:01:43,180 Yeah. Great. Put the emphasis on them. The rarest of all is the Hector's dolphin, isn't it? They are endangered, aren't they? I think that's mainly because so many of them get tangled up in fishing gear, especially gill nets, and die. I know that some conservationists are worried about the impact of the tourism industry on dolphin numbers, but I don't think that's a problem yet here. 00:02:07,320 Also, remember that this species has a very long reproductive cycle, so their numbers don't get replenished quickly. 00:02:15,000 Yeah, that's really sad, but at least the New Zealand government established a sanctuary for them, didn't it? The fishing industry was against it, but I remember reading that the general public were very supportive of the decision. It was a consequence of a study done by some marine biologists. Having a protected breeding area has made a big difference to the dolphin population already. 00:02:38,780 Yeah. I think their numbers have swelled to over seven thousand in total, with a tiny group of just eighty-nine living down off Southland, nearly two thousand living near Christchurch on the east coast, and the biggest group surviving off the west coast. It's pretty wild country over there, so I guess there aren't as many tourists and fishermen to disturb them. 00:03:01,020 Before you hear the rest of the discussion, you have some time to look at questions twenty-five to thirty on page six. 00:03:39,480 Now listen and answer questions twenty-five to thirty. 00:03:47,020 Okay. So how do you suggest I structure my part of the talk? 00:03:51,540 Well, you could start with the common dolphin, which inhabits the whole of the sea around New Zealand, and once you've covered everything to do with them, feeding and so on, you could go on to the more unusual types. The dusky dolphin is especially interesting because you know how all the dolphins travel in small social groups called pods? Well, the dusky dolphins travel in pods as big as eight hundred members. 00:04:15,220 And I think the duskies like to travel along beside fishing and tourist boats, don't they? Whereas the Hector's dolphins are different in that they prefer to go in the wake of boats. That is coming along in the rear. 00:04:29,200 Yeah, they do. But they also dive down deep to avoid fast boats. 00:04:34,400 Oh, let's not forget the Maui, because they are endangered too, aren't they? There are only a hundred and fifty of them left, and they inhabit only the western coastal waters off the North Island of New Zealand. 00:04:47,300 Yeah, it's a pity. They also face problems because of their tiny size. Hmm. Now, the orca is actually a dolphin too, right? 00:04:55,440 Yes, surprisingly. So I'll include that in my talk. People call them killer whales, but in fact, they're not whales. They're a huge and very fierce type of dolphin. In New Zealand, Kaikoura in the South Island is the best place to spot orcas swimming by. So people mistakenly think that's where they live, but actually orcas cover vast distances. 00:05:18,880 Let's not forget to mention the bottlenose. It's bigger than nearly all the other dolphins, even the common dolphin. 00:05:25,380 Oh, but still not as big as the orca, right? 00:05:28,020 That's right. Well, I think that's our presentation done now. 00:05:34,860 That is the end of section three. You now have half a minute to check your answers. ## 题目与答案 ### 21. 21 What is the students' purpose in mentioning the way dolphins make sounds? 21 What is the students' purpose in mentioning the way dolphins make sounds? - to show comparison with human speech - to show the unusual anatomy of a dolphin's head - to show recent developments in understanding the meaning of the sounds **答案**：to show the unusual anatomy of a dolphin's head 原文定位：They have tongues and larynxes as humans do, but what's really strange about the dolphin is that the sounds are focused through an extraordinary organ called the melon, which most other sea mammals don't have 同义替换：「the way dolphins make sounds」↔「the sounds are focused through an extraordinary organ」；「unusual」↔「really strange;extraordinary」；「anatomy of a dolphin's head」↔「an extraordinary organ called the melon」 ### 22. 22 According to Fran, Hector's dolphins are unaffected by 22 According to Fran, Hector's dolphins are unaffected by - tourist numbers. - the threat from fishing nets. - their slow breeding rate. **答案**：tourist numbers. 原文定位：I know that some conservationists are worried about the impact of the tourism industry on dolphin numbers, but I don't think that's a problem yet here 同义替换：「Hector's dolphins」↔「dolphin」；「are unaffected by」↔「that's not a problem yet;no impact」；「tourist numbers」↔「the tourism industry」 ### 23. 23 The New Zealand Government set up a marine sanctuary 23 The New Zealand Government set up a marine sanctuary - because of public pressure. - as a result of scientific research. - to protect a dolphin feeding ground. **答案**：because of public pressure. 原文定位：Yeah, that's really sad, but at least the New Zealand government established a sanctuary for them, didn't it?
