Part 3.
2
You will hear two marine biology students discussing a lecture on marine biodiversity and conservation from a visiting speaker.
3
First, you have some time to look at questions 21, to 24.
4
Now listen carefully and answer questions 21 to 24.
5
That lecture from the visiting speaker yesterday was good, wasn't it?
6
Yeah, I learned a lot from her about ocean biodiversity.
7
i've already done some reading on it
8
and i did an assignment on some of the problems associated with it last year
9
But I especially liked the way her lecture focused on more long -term issues.
10
Yes, things that aren't currently receiving widespread attention, but are likely to be important in the future.
11
That impressed me too.
12
It wasn't exactly a feel -good conclusion because it's hard to see any real solution for a lot of the problems.
13
No. Though she did point to where policy changes could be made to protect our marine and coastal environments.
14
Hmm, but that's just at a national level.
15
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.
16
Yes, me too.
17
The research project she described was impressive, wasn't it?
18
I'd have thought it was quite unusual to have so many experts working together.
19
Yeah, and from such different backgrounds.
20
Must have been a really exciting team to work with.
21
I'd heard of a couple of them before.
22
They were involved in research way back in 2009, warning about the dangers of ocean pollution.
23
But now people are much more aware of that, aren't they?
24
I suppose so.
25
Another thing about the research is that the team members came from all round the world.
26
Though I suppose that's not unusual nowadays.
27
Now everyone can work remotely.
28
Right.
29
I like the way she didn't bombard us with figures.
30
I mean, they were available, but she focused more on the general points they indicated.
31
Hmm.
32
And the description of improvements in systems used for tracking marine animals and things like robots were really interesting.
33
Yes.
34
And her description of how robotics can be used to investigate threats to biodiversity.
35
Absolutely.
36
Before you hear the rest of the discussion, you have some time to look at questions 25 to 30.
37
Now listen and answer questions 25 to 30.
38
While you're here, can we talk about the list of resources we have to evaluate for the seminar tomorrow?
39
I've had a look at them all, but it's been a bit of a rush.
40
Yeah.
41
What did you think of that article on invasive lionfish?
42
the one claiming they were expanding their habitat throughout the Mediterranean Sea.
43
Well, the writer went on about how dangerous they were in environmental terms,
44
which is probably true, But he didn't really provide much information to explain why.
45
I know what you mean.
46
I watched the documentary on microplastics, at least I started to, but then I found it was made ten years ago, so I gave up.
47
I watched to the end, but you're right, it was showing its age.
48
People had hardly heard of microplastics then, whereas now everyone knows about them and how dangerous they are.
49
Yeah.
50
Did you listen to the podcast on ocean pollution?
51
Hmm.
52
I didn't get anything out of it, though.
53
Most of it was stating the obvious.
54
Yes.
55
It mentioned pesticides and plastic and things, and it clearly made the point that they were a bad thing.
56
But everybody knows that anyway.
57
Did you read that book on coastal ecosystems?
58
The one by John Harper?
59
Yes, I found it hard going at first.
60
It went into a lot of detail about things like the effects of offshore wind farms and fish farms, but actually...
61
I ended up with a much better understanding of the issues.
62
Yes, I agree, and I thought it was a well -written summary of those.
63
And the diagrams helped a lot too.
64
The article on metal toxicity was way above my head.
65
I didn't know anything about how metals from industrial emissions react in the ocean, and I still don't understand it.
66
I gave up reading after the first chapter.
67
I just couldn't follow it.
68
That podcast on floating marine cities was interesting, though it presented a rather one -sided picture, I thought.
69
Yes, it focused on how this would benefit people and ignored the effects on the environment.
70
But anyway, shall we talk about...
71
That is the end of part three.
72
You now have 30 seconds to check your answers to part three.

为什么要通过这个视频练习口语？

通过观看和聆听这段有关海洋生物多样性和保护的讨论，您可以为自己创造一个真实的交流环境。这种情境提供了丰富的语境，使您能够更好地了解如何在实际对话中应用您的英语技能。与其它视频相比，看YouTube学英语 的优势在于，视频内容不仅生动且富有教育意义，可以帮助您提高英语发音。

语法与表达在语境中的应用

  • 疑问句的应用：视频中频繁使用疑问句，例如“那场讲座昨天很棒，对吧？”这些疑问句不仅推动了对话的进行，还使得交谈显得更为自然。
  • 过去完成时的使用：谈话者提到“我去年做了一项有关它的作业”，展示了如何用过去完成时描述过去的事件，从而提供了更多的背景信息。
  • 强调句：例如，“我尤其喜欢她的讲座关注长期问题。”这里使用了强调结构，让说话者的观点更加突出。

常见发音难点

在视频中，某些单词的发音对学习者来说可能会有所挑战。尤其是“biodiversity” (生物多样性) 和 “conservation” (保护) 这些学术性词汇，需特别注意其准确发音。建议在学习中利用 英语影子跟读 的方法来模仿视频中的发音，帮助您克服这些发音难点。注意讲者的语调和重音，以提高您的 提高英语发音 能力，确保更流利的沟通。

将这些交流技巧与 shadowspeak 相结合，能帮助您在实际环境中更有效地运用英语。在利用网络资源的同时，记得多做实践，您将会发现自己在日常对话中的表现大大提升。

视频中的语法

说话人最常用的结构，并附上视频中的原话：

结构视频中的用法
被动语态 be + 过去分词 — 强调发生了什么，而不是谁做的could be made · were involved · was made
现在完成时 have/has + 过去分词 — 过去发生但与现在仍有关联的事i've already done · have thought

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
