英国新闻听力 英国鲸鱼和英国鲨鱼（在线收听）

Have a listen to this. That is a short extract from Ali Harrison’s upcoming documentary Britain's Whales and Britain's Sharks. In it, the body of a nine-metre humpback whale drowned and washed up on a coast is returned to the ocean to review how its death can sustain ocean life. And it resulted in the largest gathering of sharks ever recorded in UK waters. She spoke to the BBC.

There was two sides to me. The night before when my co-presenter had the opportunity to dive first when there were just a few blue sharks on our whale. And then it was my turn. It’s sort of six o’clock next morning. Conditions change quite a lot overnight, you know. Every single way you turned, there were blue sharks coming out from the darkness. Every single way you turned. It was incredible.

Two hundred blue sharks. You didn’t sound scared in that clip. But I understand that one of the divers who was with you actually got a bit of a nip from one of the sharks?

Yes, yeah that’s right. They’ve been there for a little while, so we had our cameraman and a really experienced dive crew who were supporting all of our activities. Things sort of change. Once I got in the water, I think what happened was there was a lot more talking. And it sends out a lot of electrical signals into the water which started to change the behavior of the sharks. And I think once all that activities started, one of them got a little bit excitable and gave him a nip, which he was actually delighted about it. This is quite a badge of honour to have.

I bet. He was trying to be polite to the shark. But let’s talk about the whale. Tell us about that. I mean, you’d never done this before obviously. And this has been the biggest number of sharks all together. What was that like? Describe it first.

It was incredibly difficult. It took us three years just to get to this stage because we have people on watchout waiting for the right size. It has to be not too big and not too small. And eventually we got this humpback who tragically died. But the logistics of getting a whale, it took the permissions of fifteen different government agencies and then freezing experts to get this whale back out into the sea. It hadn’t been done before, so it’s the first ever study of its type.

And tell us what did it tell you.

We knew that there were sharks in our waters. We knew that we had about thirty different species of sharks in our waters, but we’ve never expected that to be the numbers. Seeing that number of blue sharks together has given a lot of academics a lot of behaviour that they are able to write up about and not really knowing that they could congregate in numbers this big, that was probably our biggest finding.

听一下这个。这是阿里?哈里森即将发行的纪录片《英国鲸鱼和英国鲨鱼》中的一小段。在这个片段中，人们在海岸上冲洗了一只淹死的身长9米的座头鲸然后放回海洋，看它的死亡如何维持海洋生命，结果引发英国水域有记录以来最大规模的鲨鱼聚集。她接受了BBC的采访。

对我来说有两个方面。前一天晚上，我的合伙人抓住机会率先潜水，当时我们的鲸鱼身上只有几只大青鲨。然后就轮到我了。大概早上6点，情况一夜之间变了很多。你每一次转身，都有大青鲨从黑暗处游出。每转一次身都有，简直不可思议。

二百只大青鲨。视频里听不出来你害怕。但据我了解，和你一起的潜水员被鲨鱼咬了一下。

对，没错。他们在里面有一会儿了，所以我们让摄影师和提供活动支持的经验丰富的潜水队下去了。情况有点变化。我一下水就明白了，话说的有点多了，向水中发出许多电信号，改变了鲨鱼的行为。我认为那种活动一开始就激怒了一条鲨鱼，咬了他一下，他还挺高兴，像是得了一枚荣誉勋章。

那肯定。他是尽量对那条鲨鱼客气。我们先聊聊那头鲸鱼吧，跟我们讲讲。很显然您以前从来没有做过这个事，而且这是有史以来最大数量的鲨鱼聚在一起，那是怎样的场面？先描述一下。

实在太难了。我们花了三年时间才到这个阶段，因为得让人一直观察，等待适合的大小，不能太大也不能太小。最后，我们等到了这头死得很惨的座头鲸。但为了获取一头鲸鱼，需要15个政府机构的批准以及冻结专家，才能把鲸鱼运回海里。这个以前从来没人做过，所以是史上第一次这一类型研究。

跟我们讲讲你们收到了什么信息。

我们当时知道英国海域有鲨鱼，大概有30种鲨鱼，但是想不到数量有那么多。看到那么多大青鲨，给了专业学者很多可以记载的素材，也没想到那么多鲨鱼可以聚集，这或许是我们最大的发现。
