So a body called the Global Marine Species Assessment is now creating a list of endangered species on land.
So they consider things like the size of the population — how many members of one species there are in a particular place
and then they look at their distribution in geographical terms.
Although this is quite difficult when you're looking at fish, because they're so mobile,
and then thirdly the calculate the rate at which the decline of the species is happening.
So far only 1,500 species have been assessed, but they want to increase this figure to 20,000.
For each one they assess, they use the data they collect on that species to produce a map showing its distribution.
Ultimately they will be able to use these to figure out not only where most species are located but also where they are most threatened.
So finally, what can be done to retain the diversity of species in the world's oceans?
Firstly, we need to set up more reserves in our oceans, places where marine species are protected.
We have some, but not enough.
In addition, to preserve species such as leatherback turtles,
which live out in the high seas but have their nesting sites on the American coast,
we need to create corridors for migration, so they can get from one area to another safely.
As well as this, action needs to be taken to lower the levels of fishing quotas to prevent overfishing of endangered species.
And finally, there's the problem of 'by-catch'.
This refers to the catching of unwanted fish by fishing boats — they're returned to the sea, but they're often dead or dying.
If these commercial fishing boats used equipment which was more selective,
so that only the fish wanted for consumption were caught, this problem could be overcome.
OK. So does anyone have any questions...
但是，生物学家仍不知道每种生物的生存受到的威胁有多么严重。
于是现在一个名叫Global Marine Species Assessment 的组织正在编写一份陆地上濒危物种的名单。
他们考虑的是像族群规模（特定地区内某一生物的数量有多少）这样的因素，
然后，他们便着眼于这些生物在地理上的分布。
不过这一点在观察鱼类的时候相当困难，因为它们流动性太大了。
第三步是计算这种生物数量减少的比率。
到目前为止，他们只评估了1500种生物，不过他们希望将这一数字增加到20000。
他们在评估每一种生物时，都会用他们收集到的关于这种生物的数据来绘制一幅地图，显示它们的分布。
最终，他们将不仅可以通过这些地图发现大部分生物生活的地点，还能弄清楚它们在哪里受到的威胁最大。
那么，要保持世界海洋中的生物多样性，我们能做些什么呢？
首先，我们要在海洋中设置更多自然保护区，在保护区内海洋生物可以受到保护。
目前海洋中已经有了一些保护区，但是还远远不够。
另外，还有一些生物比如棱皮龟，
它们生活在外海中，但是筑巢点却在美国海岸，为了保护它们，
我们需要建立一些迁徙廊道，这样它们就能从一个地区安全地到达另一个地区了。
除此之外，我们还需要采取行动降低捕鱼限额，以防止濒危物种被过度捕捞。
最后，还存在“副渔获”的问题。
“副渔获”指的是渔船会捕捞到不想要的鱼类，他们通常会把这些鱼放回大海，但是放生时这些鱼一般已经死了或者命不久矣。
如果这些商业捕渔船能够使用挑选更加仔细的设备，
以便只捕捞想要消费的鱼类，那么这个问题就能得以解决了。
好了，有人想要问我问题吗...
2.阅读包答案：
传说在内战(1861--1865)快结束的某个时候，一列载着牛群的政府的火车在穿过怀俄明州东部的北部平原时遇到了暴风雪，因此不得不被遗弃。
3.写作包答案：
About 10 years has passed since China first sent a man into space. Yang Liwei orbited the Earth 14 times during his complete 21-hour flight with the Shenzhou 5 spacecraft in 2003. More than 40 years after Yuri Gagarin’s groundbreaking journey, China has become the third country after the former Soviet Union and the US to carry out an independent manned space flight. And China has successfully launched its first target spacecraft and space laboratory, Tiangong-1.
