Now listen carefully and answer questions 21 to 26.

现在请仔细听，并回答第21至第26题。

TUTOR: Thanks for coming along, Nadia and Fergus. So this is a chance for you to give us some feedback about different aspects of your course. What would you like to begin with?

导师：感谢你们过来，纳迪亚和弗格斯。这是一个机会让你们对课程的不同方面给我们一些反馈，你们想从哪方面开始？

NADIA: I've enjoyed the sessions on food safety. There was some information there that I found really surprising, although some was stuff I knew already, like the rise in rates of obesity.

纳迪亚：我很喜欢食品安全方面的课程。其中有些信息让我非常惊讶，尽管有些是我已经知道的，比如肥胖率的上升。

FERGUS: Yeah, that's been in the news a lot. But I hadn't realised that unsafe food causes more than 200 different diseases.

弗格斯：是的，这在新闻中报道了很多。但我没有意识到不安全的食物会导致200多种不同的疾病。

NADIA: No, I'd no idea it was that many. And speaking of diseases, I knew resistance to antibiotics is on the increase, but I didn't know why...

纳迪亚：不，我完全不知道有那么多。说到疾病，我知道抗生素耐药性在增加，但我不知道为什么……

FERGUS: …that it's partly because when animals are treated with antibiotics then consumed by humans, the antibiotics get into the food chain. I had no idea about that either.

弗格斯：……这部分是因为当动物接受抗生素治疗后被人类食用，抗生素就进入了食物链。我也对此一无所知。

NADIA: Then the sessions provided a lot of information about plastic pollution from food packaging in the ocean, but I think that most of us were already aware of that.

纳迪亚：然后课程提供了大量关于食品包装海洋塑料污染的信息，但我认为我们大多数人已经知道这一点了。

FERGUS: Yeah. But I thought we could have done more on how much food is thrown away unnecessarily through fear of it being out of date, that was only mentioned in passing.

弗格斯：是的。但我认为我们本可以更多地讨论由于担心过期而不必要地丢弃了多少食物，这只是顺带提到了一下。

TUTOR: OK, I'll bear that in mind. What did you think about the sessions from visiting lecturers, Fergus?

导师：好的，我会记住这点的。弗格斯，你觉得客座讲师的课程怎么样？

FERGUS: For me the most interesting one was about that project to prevent companies giving incorrect information to consumers about food.

弗格斯：对我来说最有趣的是关于阻止公司向消费者提供关于食品不实信息的项目。

TUTOR: Ah, food fraud, yes.

导师：啊，食品欺诈，是的。

FERGUS: I thought it was really good to address a problem that's faced by so many different groups – people with special religious rules, as well as vegetarians and vegans.

弗格斯：我认为解决如此多不同群体面临的问题真的很好——有特殊宗教规定的人，以及素食者和纯素食者。

NADIA: And those with allergies.

纳迪亚：还有过敏人群。

FERGUS: Yeah. And another thing, we've had effective ways of analysing DNA for some time now and these can easily be applied to analysing food.

弗格斯：是的。另外，我们已经有了分析DNA的有效方法，这些方法可以很容易地应用于食品分析。

But what the researchers succeeded in doing was to ensure that these tests were carried out at different stages in the food's journey from the producer to the consumer.

但研究人员成功做到的是确保这些测试在食品从生产者到消费者的旅程的不同阶段进行。

NADIA: So they knew that the food actually came from the place it was supposed to, and had the ingredients it was meant to.

纳迪亚：这样他们就知道食物实际上来自应该来自的地方，并含有应该含有的成分。

FERGUS: Exactly. So customers can be confident about what they buy.

弗格斯：正是如此，所以顾客可以对他们购买的东西有信心。

NADIA: And the researchers had a good system for publicising their findings too.

纳迪亚：研究人员也有一套很好的系统来公布他们的发现。

FERGUS: Well, I thought there were some problems with that, actually.

弗格斯：嗯，我认为实际上那方面存在一些问题。

TUTOR: OK. And do you have any recommendations for new topics that we could include in the course?

导师：好的，你们对可以纳入课程的新主题有什么建议吗？

NADIA: Well, I'm interested in how crop yields can be increased without damaging the environment.

纳迪亚：嗯，我对如何在不损害环境的情况下提高作物产量感兴趣。

FERGUS: But we've already done quite a bit on that – but not so much on the seafood industry, where stocks are in danger of being overexploited as a food source unless we can find ways of keeping stocks up.

弗格斯：但我们已经涉及了相当多这方面的内容——但在海鲜行业方面涉及不多，该行业的储量面临被过度开发作为食物来源的危险，除非我们能找到维持储量的方法。

NADIA: Yes, that'd be a good topic. And I'm interested in the idea of a personalised approach to diet, now we have the technology to analyse exactly what individuals need.

纳迪亚：是的，那将是个好主题。我对个性化饮食方法的想法感兴趣，现在我们有技术可以准确分析个人需要什么。

FERGUS: That sounds more like a medical topic than food science.

弗格斯：那听起来更像是医学主题而非食品科学。

NADIA: OK. What about sessions on the variety of food and eating habits around the world? That's very relevant nowadays.

纳迪亚：好的，那么关于世界各地食物多样性和饮食习惯的课程怎么样？这在当今非常相关。

FERGUS: Yes, I think the whole class would be interested in that.

弗格斯：是的，我认为全班同学都会对此感兴趣。

NADIA: Then there's technological stuff, things like 3D printing of food and smart packaging.

纳迪亚：然后还有技术方面的内容，比如食品3D打印和智能包装。

FERGUS: Mmm – maybe too specialist.

弗格斯：嗯——也许太专业了。
