1.听写包答案：

I've been looking at ocean biodiversity, that's the diversity of species that live in the world's oceans.

About 20 years ago biologists developed the idea of what they called 'biodiversity hotspots'.
These are the areas which have the greatest mixture of species, so one example is Madagascar.
These hotspots are significant because they allow us to locate key areas for focusing efforts at conservation.
Biologists can identify hotspots on land, fairly easily,
but until recently, very little was known about species distribution and diversity in the oceans,
and no one even knew if hotspots existed there.
Then a Canadian biologist called Boris Worm did some research in 2005 on data on ocean species that he got from the fishing industry.
Worm located five hotspots for large ocean predators like sharks, and looked at what they had in common.
The main thing he'd expected to find was that they had very high concentrations of food
but to his surprise that was only true for four of the hotspots — the remaining hotspot was quite badly off in that regard.
But what he did find was that in all cases,
the water at the surface of the ocean had relatively high temperatures even when it was cool at greater depths,
so this seemed to be a factor in supporting a diverse range of these large predators.
However, this wasn't enough on its own, because he also found that the water needed to have enough oxygen in it
so these two factors seemed necessary to support the high metabolic rate of these large fish.
A couple of years later, in 2007, a researcher called Lisa Ballance, who was working in California,
also started looking for ocean hotspots, but not for fish
what she was interested in was marine mammals things like seals.
And she found three places in the oceans which were hotspots,
and what these had in common was that these hotspots were all located at boundaries between ocean currents,
and this seems to be the sort of place that has lots of the plankton that some of these species feed on.
So now people who want to protect the species that are endangered need to get as much information as possible.
For example, there's an international project called the Census of Marine Life.
They've been surveying oceans all over the world, including the Arctic.
One thing they found there which stunned other researchers was that there were large numbers of species which live below the ice
sometimes under a layer up to 20 meters thick.
Some of these species had never been seen before.
They've even found species of octopus living in these conditions.
And other scientists working on the same project,
but researching very different habitats on the ocean floor,
have found large numbers of species congregating around volcanoes, attracted to them by the warmth and nutrients there.
我最近一直在关注海洋生物多样性，也就是生活在世界海洋中的生物的多样性。
大约20年前，生物学家提出了他们称为“生物多样性热点地区”的概念。
这些地区拥有最大的混合物种群体，其中一个例子就是马达加斯加。
这些热点地区至关重要，因为它们给了我们锁定关键地区集中力量进行生物保护的机会。
生物学家们能够相当轻易地辨认出陆地上的热点地区，
但是直到最近之前，人们对海洋中的生物分布和多样性都知之甚少，
甚至没人知道海洋中是否存在这样的热点地区。
接着在2005年，一个叫Boris Worm的加拿大生物学家从捕鱼业中获得了关于海洋物种的数据，并对其进行了研究。
Worm锁定了海洋中像鲨鱼这样的大型食肉动物生活的五个热点地区，然后研究了它们的共同点。
他预计会出现的主要共同点是，在这些地区都有高度集中的食物来源，
但是令他感到意外的是，这一观点只适用于其中四个热点地区，剩下的那个地区在这方面境况十分不佳。
不过他在所有案例中都发现了的一件事是，
即使那些海域深处的水温较低，但它们表层水温都相对较高。
这一点似乎能够成为支持大型海洋食肉动物多样化分布的因素。
但是只有这一点还远远不够，因为他还发现海水中需要饱含足够的氧气，
于是这两个因素一起便足够证明这些大型鱼类的高代谢率观点了。
两年之后，在2007年，一位在加利福尼亚州工作的研究人员，Lisa Ballance，
也开始寻找海洋热点地区。不过她感兴趣的不是鱼类，
而是海洋哺乳动物，比如海豹。
她在海洋中找到了三个热点地区，
它们的共同之处在于，所有的这些热点地区都位于洋流的交界处。
这些海域中似乎拥有大量的浮游生物可供海洋哺乳动物食用。
如今人们想要保护濒危物种的话，就要尽可能多地获取相关信息。
举个例子来说，有一个国际工程叫做Census of Marine Life。
他们调查了世界上所有的海洋，包括北极地区的海洋。
他们在那儿发现了令其他研究人员瞠目结舌的一件事，那就是冰层之下生活着大量的生物物种，
有些甚至生活在20米厚的冰层之下。
这些物种中有些人们之前从未见过。
他们甚至还发现一种章鱼也生活在这种环境中。
其他科学家也从事同样的研究，
但他们研究的是海底的一些非常与众不同的栖息地。
他们发现有大量生物聚集在海底火山周围，吸引它们过来的是那里温暖的海水和丰富的营养物质。

这些研究人员已经力图证实他们的工作不仅可以成为科学而且还是历史的宝贵工具，为了解普通人的日常生活提供崭新的观点，否则这些普通人的生存状态不可能被记载得这么好。

3.写作包答案：

Thanks to the power of the Internet, Chinese Wuxia series are becoming increasingly popular in the West. Wuxia is a genre of Chinese fiction related to martial artists. It appears in various forms of media, from video games to movies. Many westerners cannot understand Chinese at all, but they don't mind reading the translated English words on the screen. The lack of promotion and basic knowledge of Wuxia are among the reasons why the genre previously spread slowly in the West.
