Ocean Research剑桥雅思7-听力原文翻译及答案解析

一、Ocean Research听力原文：

SIMON:Thanks to all of you for coming along today to hear about how the robotic float project is helping with ocean research.

Well,first of all we’ll look at what a robotic float does and its use.

So let's start with the device itself.

It looks a bit like a cigar and it's about one and a half metres long.

More importantly it's full of equipment that’s designed to collect data.

So,it can help us in building up a profile of different factors which work together within the world's oceans.

STUDENT 1:Sounds like a big project-isn't it too big for one country to undertake?

SIMON:That's quite true but this project is a really good example of international co-operation.

Over the last five years scientists from thirteen countries have been taking part in the project and launching floats in their area of ocean control.

And next year this number will rise to fourteen when Indonesia joins the project.

STUDENT 2:That’s impressive.

SIMON:But let’s move onto how floats work.

SIMON:The operational cycle goes like this.

Each of the floats is dropped in the ocean from a boat at a set point and activated from a satellite.

Then the float immediately sinks about 2,000 metres...

that's two whole kilometres down in the water.

It stays at this depth for about 10 days and is carried around by the currents which operate in the ocean at this level.

During this time it’s possible for it to cover quite large distances but the average is fifty kilometres.

STUDENT 2:So what is it actually recording?

SIMON:Well at this stage nothing,but as it rises to the surface it collects all sorts of data,most importantly variations in salinity,that's salt levels,and the changes in temperature,a bit like underwater weather balloons.

Then when it gets back to the surface all the data it’s collected is beamed up to the satellite.

After about five hours on the surface the float automatically sinks,beginning the whole process again.

STUDENT 1:What happens to the data?

SIMON:Well the information is transferred direct to onshore meteorological stations...

like our one in Hobart...

and within four hours the findings can be on computers and they can be mapped and analysed.

STUDENT 2:You say you’re building models of the world's ocean systems but how*re they going to be used,and more importantly,when?

SIMON:Some of the data has already helped in completing projects For example,our understanding of the underlying causes of El Niflo events is being confirmed by float data.

Another way we're using float data is to help us to understand the mechanics of climate change,like global warming and ozone depletion.

That’s part of an ongoing variability study but the results are still a long way off.

However,this is not the case with our ocean weather forecasting.

Because we know from the floats what the prevailing weather conditions will be in certain parts of the ocean,we can advise the navy on search and rescue missions.

That's happening right now and many yachtsmen owe their lives to the success of this project.

In addition,the float data can help us to look at the biological implications of ocean processes.

STUDENT 1:Would that help with preserving fish stocks?

SIMON:Yes,and advising governments on fisheries legislation.

We're well on the way to completing a project on this.

We hope it will help to bring about more sustainable fishing practices.

We’ll be seeing the results of that quite soon.

STUDENT 2:It sounds like the data from floats has lots of applications.

SIMON:Yes it does.

It’s also a powerful agricultural tool.

If we were aware of what the weather would be like,say,next year,we could make sure that the farmers planted appropriate grain varieties to produce the best yield from the available rainfall.

STUDENT 1:That sounds a bit like science fiction,especially when now we can’t even tell them when a drought will break.

SIMON:I agree that this concept is still a long way in the future,but it will come eventually and the float data will have made a contribution.

二、Ocean Research听力中文翻译：

西蒙：感谢大家今天来到这里，了解机器人浮子项目是如何帮助海洋研究的。

首先，我们来看看机器人浮子的功能和用途。

让我们从设备本身开始。

它看起来有点像雪茄，大约一米半长。

更重要的是，它装满了用来收集数据的设备。

因此，它可以帮助我们建立世界海洋中共同作用的不同因素的概况。

学生1：听起来像是一个大项目——对一个国家来说是不是太大了？

西蒙：没错，但这个项目是国际合作的一个很好的例子。

过去五年来，来自13个国家的科学家一直在参与该项目，并在其海洋控制区内发射浮标。

明年，当印尼加入该项目时，这个数字将上升到14个。

学生2：真令人印象深刻。

西蒙：但让我们来看看浮子是如何工作的。

西蒙：运作周期是这样的。

每一个浮标都是在设定点从船上掉落到海洋中，并由卫星激活。

然后浮子立即下沉约2000米。。。

水下有整整两公里。

它在这个深度停留了大约10天，并被在这个高度的洋流所携带。

在这段时间内，它可以覆盖相当长的距离，但平均距离为50公里。

学生2：那么它实际上记录了什么？

西蒙：在这个阶段什么都没有，但当它上升到水面时，它收集了各种数据，最重要的是盐度的变化，也就是盐含量和温度的变化，有点像水下气象气球。

然后，当它返回地面时，它收集的所有数据都被传送到卫星上。

浮子在水面上停留大约五个小时后自动下沉，整个过程再次开始。

学生1：数据会发生什么变化？

西蒙：信息直接传送到陆上气象站。。。

就像我们在霍巴特的那个。。。

在四个小时内，这些发现就可以在计算机上进行绘制和分析。

学生2：你说你正在建立世界海洋系统的模型，但它们将如何使用，更重要的是，何时使用？

西蒙：一些数据已经有助于完成项目，例如，我们对厄尔尼诺事件潜在原因的理解正在通过浮动数据得到证实。

我们使用浮动数据的另一种方式是帮助我们了解气候变化的机制，如全球变暖和臭氧消耗。

这是一项正在进行的变异性研究的一部分，但其结果还有很长的路要走。

然而，我们的海洋天气预报并非如此。

因为我们从浮标上知道海洋某些地区的主要天气状况，所以我们可以就搜索和救援任务向海军提供建议。

这件事现在正在发生，许多游艇驾驶员将他们的生命归功于这个项目的成功。

此外，浮标数据可以帮助我们了解海洋过程的生物学意义。

学生1：这有助于保护鱼类资源吗？

西蒙：是的，还就渔业立法向政府提供咨询。

我们正在顺利完成这方面的一个项目。

我们希望这将有助于实现更可持续的捕鱼做法。

我们很快就会看到结果。

学生2：听起来来自float的数据有很多应用程序。

西蒙：是的。

它也是一种强大的农业工具。

如果我们知道天气会是什么样子，比如说明年，我们可以确保农民种植适当的谷物品种，以利用现有的降雨量获得最佳产量。

学生1：这听起来有点像科幻小说，尤其是现在我们甚至不能告诉他们干旱何时会结束。

西蒙：我同意这个概念在未来还有很长的路要走，但它最终会到来，浮动数据将做出贡献。

五、Ocean Research听力答案解析

21.cigar此题关键词为shaped like a，录音中用It looks like a cigar...，所以cigar为正确答案。考的是单词拼写，还有就是区分scar和cigar。

22.13(different)countries女生首先提出问题...isn’t it too big for one country to undertake?，这就是第22题的问题。所以只要听取接下来老师的回答就能找出正确答案。但是，该题的题干有一个时间陷阱：题干的时态是完成时。考生还能听到14的时候，时间是next year，所以不是正确答案。

23.activated从此题开始是一组流程图题。考生需要读图，该图的标题the operational cycle为指示词，而本题的另一个指示词为satellite。考生只要抓好这两点，就能听到答案。根据dropped可以判断and连接两个动词的过去分词，所以第二句话的activated使用被动形式，即为答案。

24.50 km(s)本题的题干关键词为average distance。考生需要认真听取关键词的出现。答案在转折词but以后出现。

25.temperature当听到录音中女生问...what is it actually recording?，考生应意识到第25题答案即将到来，salinity是定位词，已经在题干中给出来，根据语法规则判断此处and连接两个名词单数。所以当考生听到...and the changes in temperature.，就能确定答案了。

26.A当考生听到女生问...but how’re they going to be used，and more importantly,when?，考生应该意识到第26题的到来。El Niño是这道题的关键指示词。所以当考生听到...has already helped...for example...El Niño...就能确定答案。本题对时态要求较高，需要考生注意。题眼是现在完成时态，也是表达现在的概念，和at present是同义替换。

27.C当考生听到录音中出现...climate change...，意味着第27题答案即将到来，后面出现了转折...but the results are still a long way off.。一般情况下，转折后都有考点出现，所以可以确定答案。同义替换a long way off=in the long-term future。

28.A当听到录音中男老师提到...we can advise the navy on search and rescue missions...，对应题目中的naval rescues，考生应意识到第28题答案即将到来。...that’s happening right now...提示正确答案。同义替换right now=at present。

29.B考生可以清楚地听到录音出现完整的题干...sustainable fishing practices.。正确答案紧随其后，We’ll be seeing the results of that quite soon.。quite soon提示答案。同义替换：quite soon=in the near future。

30.C考生听到...agricultural tool...grain varieties...时，应该意识到答案的出现。本题需要考生耐心。因为正确答案一直到最后才出现...a long way in the future...。同义替换：a long way in the future=in the long-term future。
