Now listen carefully and answer questions 21 to 24.

现在请仔细听，并回答第21至第24题。

PHIL: That lecture from the visiting speaker yesterday was good, wasn't it?

菲尔：昨天客座讲师的讲座很精彩，不是吗？

LUCY: Yeah. I learned a lot from her about ocean biodiversity. I've already done some reading on it, and I did an assignment on some of the problems associated with it last year, but I especially liked the way her lecture focused on more long-term issues.

露西：是的，我从她那里学到了很多关于海洋生物多样性的知识。我之前已经读了一些相关资料，去年还做了一篇关于相关问题的作业，但我特别喜欢她的讲座聚焦于更长远问题这一点。

PHIL: Yes, things that aren't currently receiving widespread attention but are likely to be important in the future. That impressed me too. It wasn't exactly a feel-good conclusion because it's hard to see any real solution for a lot of the problems.

菲尔：是的，那些目前还没有得到广泛关注但将来可能很重要的事情。这也让我印象深刻。结论并不令人振奋，因为很多问题很难看到真正的解决方案。

LUCY: No, though she did point to where policy changes could be made to protect our marine and coastal environments.

露西：确实，不过她确实指出了可以在哪些方面进行政策变革来保护我们的海洋和沿海环境。

PHIL: Mm. But that's just at a national level. The examples she gave were at a more global level, and they really made it clear to me just how wide-ranging the threats to ocean biodiversity are.

菲尔：嗯，但那只是在国家层面。她举的例子更具全球性，让我真正清楚地认识到对海洋生物多样性的威胁是多么广泛。

LUCY: Yes, me too.

露西：是的，我也是。

PHIL: The research project she described was impressive, wasn't it? I'd have thought it was quite unusual to have so many experts working together.

菲尔：她描述的研究项目令人印象深刻，不是吗？我本以为有这么多专家合作是相当罕见的。

LUCY: Yeah, and from such different backgrounds. Must have been a really exciting team to work with. I'd heard of a couple of them before – they were involved in research way back in 2009 warning about the dangers of ocean pollution.

露西：是的，而且来自如此不同的背景，与这样的团队合作一定非常令人兴奋。我之前听说过其中几位——他们早在2009年就参与了关于海洋污染危害的研究警告。

PHIL: But now people are much more aware of that, aren't they?

菲尔：但现在人们对此更加了解了，不是吗？

LUCY: I suppose so.

露西：我想是的。

PHIL: Another thing about the research is that the team members came from all round the world. Though I suppose that's not unusual nowadays, now everyone can work remotely.

菲尔：关于这项研究的另一点是，团队成员来自世界各地。不过我想如今这并不罕见，现在大家都可以远程工作了。

LUCY: Right. I liked the way she didn't bombard us with figures – I mean, they were available, but she focused more on the general points they indicated.

露西：对。我喜欢她没有用大量数据轰炸我们——我是说，数据是有的，但她更专注于数据所揭示的总体要点。

PHIL: Mm. And the description of improvements in systems used for tracking marine animals and things like robots were really interesting.

菲尔：嗯，关于用于追踪海洋动物的系统改进以及机器人等内容的描述真的很有趣。

LUCY: Yes, and her description of how robotics can be used to investigate threats to biodiversity.

露西：是的，还有她关于如何利用机器人技术调查生物多样性威胁的描述。

PHIL: Absolutely.

菲尔：完全同意。
