Ocean Research劍橋雅思7-聽力原文翻譯及答案解析

一、Ocean Research聽力原文：

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聽力中文翻譯：

西蒙：感謝大家今天來到這里，了解機器人浮子項目是如何幫助海洋研究的。

首先，我們來看看機器人浮子的功能和用途。

讓我們從設(shè)備本身開始。

它看起來有點像雪茄，大約一米半長。

更重要的是，它裝滿了用來收集數(shù)據(jù)的設(shè)備。

因此，它可以幫助我們建立世界海洋中共同作用的不同因素的概況。

學(xué)生1：聽起來像是一個大項目——對一個國家來說是不是太大了？

西蒙：沒錯，但這個項目是國際合作的一個很好的例子。

過去五年來，來自13個國家的科學(xué)家一直在參與該項目，并在其海洋控制區(qū)內(nèi)發(fā)射浮標。

明年，當印尼加入該項目時，這個數(shù)字將上升到14個。

學(xué)生2：真令人印象深刻。

西蒙：但讓我們來看看浮子是如何工作的。

西蒙：運作周期是這樣的。

每一個浮標都是在設(shè)定點從船上掉落到海洋中，并由衛(wèi)星激活。

然后浮子立即下沉約2000米。。。

水下有整整兩公里。

它在這個深度停留了大約10天，并被在這個高度的洋流所攜帶。

在這段時間內(nèi)，它可以覆蓋相當長的距離，但平均距離為50公里。

學(xué)生2：那么它實際上記錄了什么？

西蒙：在這個階段什么都沒有，但當它上升到水面時，它收集了各種數(shù)據(jù)，最重要的是鹽度的變化，也就是鹽含量和溫度的變化，有點像水下氣象氣球。

然后，當它返回地面時，它收集的所有數(shù)據(jù)都被傳送到衛(wèi)星上。

浮子在水面上停留大約五個小時后自動下沉，整個過程再次開始。

學(xué)生1：數(shù)據(jù)會發(fā)生什么變化？

西蒙：信息直接傳送到陸上氣象站。。。

就像我們在霍巴特的那個。。。

在四個小時內(nèi)，這些發(fā)現(xiàn)就可以在計算機上進行繪制和分析。

學(xué)生2：你說你正在建立世界海洋系統(tǒng)的模型，但它們將如何使用，更重要的是，何時使用？

西蒙：一些數(shù)據(jù)已經(jīng)有助于完成項目，例如，我們對厄爾尼諾事件潛在原因的理解正在通過浮動數(shù)據(jù)得到證實。

我們使用浮動數(shù)據(jù)的另一種方式是幫助我們了解氣候變化的機制，如全球變暖和臭氧消耗。

這是一項正在進行的變異性研究的一部分，但其結(jié)果還有很長的路要走。

然而，我們的海洋天氣預(yù)報并非如此。

因為我們從浮標上知道海洋某些地區(qū)的主要天氣狀況，所以我們可以就搜索和救援任務(wù)向海軍提供建議。

這件事現(xiàn)在正在發(fā)生，許多游艇駕駛員將他們的生命歸功于這個項目的成功。

此外，浮標數(shù)據(jù)可以幫助我們了解海洋過程的生物學(xué)意義。

學(xué)生1：這有助于保護魚類資源嗎？

西蒙：是的，還就漁業(yè)立法向政府提供咨詢。

我們正在順利完成這方面的一個項目。

我們希望這將有助于實現(xiàn)更可持續(xù)的捕魚做法。

我們很快就會看到結(jié)果。

學(xué)生2：聽起來來自float的數(shù)據(jù)有很多應(yīng)用程序。

西蒙：是的。

它也是一種強大的農(nóng)業(yè)工具。

如果我們知道天氣會是什么樣子，比如說明年，我們可以確保農(nóng)民種植適當?shù)墓任锲贩N，以利用現(xiàn)有的降雨量獲得最佳產(chǎn)量。

學(xué)生1：這聽起來有點像科幻小說，尤其是現(xiàn)在我們甚至不能告訴他們干旱何時會結(jié)束。

西蒙：我同意這個概念在未來還有很長的路要走，但它最終會到來，浮動數(shù)據(jù)將做出貢獻。

28.A

29.B

30.C

五、Ocean Research聽力答案解析

21.cigar此題關(guān)鍵詞為shaped like a，錄音中用It looks like a cigar...，所以cigar為正確答案?？嫉氖菃卧~拼寫，還有就是區(qū)分scar和cigar。

22.13(different)countries女生首先提出問題...isn’t it too big for one country to undertake?，這就是第22題的問題。所以只要聽取接下來老師的回答就能找出正確答案。但是，該題的題干有一個時間陷阱：題干的時態(tài)是完成時?？忌€能聽到14的時候，時間是next year，所以不是正確答案。

23.activated從此題開始是一組流程圖題?？忌枰x圖，該圖的標題the operational cycle為指示詞，而本題的另一個指示詞為satellite?？忌灰ズ眠@兩點，就能聽到答案。根據(jù)dropped可以判斷and連接兩個動詞的過去分詞，所以第二句話的activated使用被動形式，即為答案。

24.50 km(s)本題的題干關(guān)鍵詞為average distance?？忌枰J真聽取關(guān)鍵詞的出現(xiàn)。答案在轉(zhuǎn)折詞but以后出現(xiàn)。

25.temperature當聽到錄音中女生問...what is it actually recording?，考生應(yīng)意識到第25題答案即將到來，salinity是定位詞，已經(jīng)在題干中給出來，根據(jù)語法規(guī)則判斷此處and連接兩個名詞單數(shù)。所以當考生聽到...and the changes in temperature.，就能確定答案了。

26.A當考生聽到女生問...but how’re they going to be used，and more importantly,when?，考生應(yīng)該意識到第26題的到來。El Ni?o是這道題的關(guān)鍵指示詞。所以當考生聽到...has already helped...for example...El Ni?o...就能確定答案。本題對時態(tài)要求較高，需要考生注意。題眼是現(xiàn)在完成時態(tài)，也是表達現(xiàn)在的概念，和at present是同義替換。

27.C當考生聽到錄音中出現(xiàn)...climate change...，意味著第27題答案即將到來，后面出現(xiàn)了轉(zhuǎn)折...but the results are still a long way off.。一般情況下，轉(zhuǎn)折后都有考點出現(xiàn)，所以可以確定答案。同義替換a long way off=in the long-term future。

28.A當聽到錄音中男老師提到...we can advise the navy on search and rescue missions...，對應(yīng)題目中的naval rescues，考生應(yīng)意識到第28題答案即將到來。...that’s happening right now...提示正確答案。同義替換right now=at present。

29.B考生可以清楚地聽到錄音出現(xiàn)完整的題干...sustainable fishing practices.。正確答案緊隨其后，We’ll be seeing the results of that quite soon.。quite soon提示答案。同義替換：quite soon=in the near future。

30.C考生聽到...agricultural tool...grain varieties...時，應(yīng)該意識到答案的出現(xiàn)。本題需要考生耐心。因為正確答案一直到最后才出現(xiàn)...a long way in the future...。同義替換：a long way in the future=in the long-term future。
