Honey Bees劍橋雅思8-聽力原文翻譯及答案解析

一、Honey Bees聽力原文：

PROFESSOR:Good morning everyone.

In today's seminar.

Grant Freeman,a biologist who specialises in identifying insects,and who works for the AustralianQuarantine Service,has come to talk to us about his current research work.

Right,well,over to you.

Grant.

GRANT:Good morning,everyone.

I'm sure that you know that the quarantine service regulates all food brought into Australia.

Well,obviously they want to protect Australia from diseases that might come in with imported goods,but they also want to prevent insect pests from being introduced into the country,and that’s where I have a part to play.

Anyway,my current research involves trying to find a particular type of bee,the Asian Honey Bee,and finding out whether there are any of them around in various states of Australia.

We discovered a few of them in Queensland once and eradicated them.

Now,we're pretty keen to make sure that there aren't any more getting in,particularly to New South Wales and other states.

STUDENT 1:What's wrong with Asian Honey Bees?

Are they so different from Australian bees?

GRANT:Well,in fact,they look almost the same,but they are infested with mites-microscopic creatures which live on them,and which can seriously damage our own home-grown bees,or could even wipe them out.

PROFESSOR:Well,what would happen if Australian bees died out?

GRANT:Well,the honey from Australian bees is of excellent quality,much better than the stuff the Asian bees produce.

In fact,Australia exports native Queen Bees to a large number of countries because of this.

When the European Honey Bee was first discovered out in the bush,we found they made really unpleasant honey and they were also too big to pollinate many of our native flowers here in Australia.

STUDENT 2:That must have had a devastating effect on the natural flora.

Did you lose any species?

GRANT:No,we managed to get them under control before that happened but if Asian bees got in there could be other consequences.

We could lose a lot of money because you might not be aware,but it’s estimated that native bees'pollination of flower and vegetable crops is worth 1.2 billion dollars a year.

So in a way they're the farmers'friend.

Oh,and another thing is,if you’re stung by an Asian Honey Bee,it can produce an allergic reaction in some people;

so they’re much more dangerous than native bees.

PROFESSOR:How will you know if Asian bees have entered Australia?

GRANT:We're looking at the diet of the bird called the Rainbow Bee Eater.

The Bee Eater doesn't care what it eats,as long as they’ve insects.

But the interesting thing about this bird is that we are able to analyse exactly what it eats and that’s really helpful if we’re looking for introduced insects.

PROFESSOR:How come?

GRANT:Because insects have their skeletons outside their bodies,so the Bee Eaters digest the meat from the inside.

Then they bring up all the indigestible bits of skeleton and,of course,the wings in a pellet-a small ball of waste material which they cough up.

PROFESSOR:That sounds a bit unpleasant.

So,how do you go about it?

GRANT:In the field we track down the Bee Eaters and find their favourite feeding spots,you know,the places where the birds usually feed.

It's here that we can find the pellets.

We collect them up and take them back to the laboratory to examine the contents.

PROFESSOR:How do you do that?

GRANT:The pellets are really hard,especially if they have been out in the sun for a few days so,first of all,we treat them by adding water to moisten them and make them softer.

Then we pull them apart under the microscope.

Everything's all scrunched up but we’re looking for wings so we just pull them all out and straighten them.

Then we identify them to see if we can find any Asian bee wings.

PROFESSOR:And how many have you found?

GRANT:So far our research shows that Asian bees have not entered Australia in any number-it's a good result and much more reliable than trying to find live ones as evidence of introduced insects.

PROFESSOR:Well,that's fascinating!

Thank you,Grant,for those insights.

I hope that you might inspire some of our students here to conduct some similar experiments.

二、Honey Bees聽力中文翻譯：

教授：大家早上好。

在今天的研討會上。

格蘭特·弗里曼（GrantFreeman）是一位專門鑒定昆蟲的生物學(xué)家，他為澳大利亞檢疫局工作，他來向我們介紹他目前的研究工作。

好吧，好吧，交給你吧。

授予

格蘭特：大家早上好。

我相信你知道檢疫局監(jiān)管所有帶入澳大利亞的食品。

很明顯，他們想保護(hù)澳大利亞免受進(jìn)口商品帶來的疾病，但他們也想防止害蟲傳入澳大利亞，這就是我要發(fā)揮的作用。

無論如何，我目前的研究涉及到尋找一種特殊類型的蜜蜂，亞洲蜜蜂，并找出澳大利亞各州是否有這種蜜蜂。

我們曾經(jīng)在昆士蘭發(fā)現(xiàn)了一些，并根除了它們。

現(xiàn)在，我們非?？释_保不再有人進(jìn)入，特別是新南威爾士州和其他州。

學(xué)生1：亞洲蜜蜂怎么了？

它們和澳大利亞蜜蜂有這么大的不同嗎？

格蘭特：嗯，事實(shí)上，它們看起來幾乎一樣，但它們布滿了螨蟲——寄生在它們身上的微小生物，可能會嚴(yán)重?fù)p害我們自己的本土蜜蜂，甚至可能將它們消滅。

教授：如果澳大利亞蜜蜂滅絕了會發(fā)生什么？

格蘭特：嗯，澳大利亞蜜蜂產(chǎn)的蜂蜜質(zhì)量很好，比亞洲蜜蜂產(chǎn)的蜂蜜好得多。

事實(shí)上，澳大利亞因此向許多國家出口本土蜂王。

當(dāng)歐洲蜜蜂第一次在灌木叢中被發(fā)現(xiàn)時(shí)，我們發(fā)現(xiàn)它們產(chǎn)的蜂蜜非常難聞，而且它們太大了，無法為澳大利亞的許多本土花朵授粉。

學(xué)生2：那一定對自然植物群產(chǎn)生了毀滅性的影響。

你失去過什么物種嗎？

格蘭特：不，在那之前我們設(shè)法控制住了它們，但如果亞洲蜜蜂進(jìn)入，可能會有其他后果。

我們可能會損失很多錢，因?yàn)槟憧赡懿恢?，但?jù)估計(jì)，本土蜜蜂為花卉和蔬菜作物授粉每年價(jià)值12億美元。

所以在某種程度上，他們是農(nóng)民的朋友。

哦，還有一件事，如果你被亞洲蜜蜂蜇了，它會對一些人產(chǎn)生過敏反應(yīng)；

所以它們比本地蜜蜂更危險(xiǎn)。

教授：你怎么知道亞洲蜜蜂是否已經(jīng)進(jìn)入澳大利亞？

格蘭特：我們正在研究彩虹食蜂鳥的飲食。

吃蜜蜂的人不在乎吃什么，只要他們有昆蟲就行。

但這種鳥的有趣之處在于，我們能夠準(zhǔn)確地分析它吃什么，如果我們在尋找引入的昆蟲，這真的很有幫助。

教授：怎么會呢？

格蘭特：因?yàn)槔ハx的骨架在體外，所以食蜂人從體內(nèi)消化肉。

然后他們拿出所有無法消化的骨骼碎片，當(dāng)然還有一個小球中的翅膀——一個他們咳出的廢料小球。

教授：聽起來有點(diǎn)不舒服。

那么，你是怎么做的？

格蘭特：在野外，我們追蹤食蜂人，找到他們最喜歡的覓食點(diǎn)，你知道，就是鳥類通常覓食的地方。

我們可以在這里找到小球。

我們把它們收集起來，帶回實(shí)驗(yàn)室檢查內(nèi)容物。

教授：你是怎么做到的？

格蘭特：這些小球真的很硬，特別是如果它們已經(jīng)在陽光下曬了幾天的話，所以，首先，我們給它們加水濕潤，讓它們更柔軟。

然后我們在顯微鏡下把它們分開。

所有的東西都蜷縮起來了，但我們正在尋找翅膀，所以我們只是把它們?nèi)坷鰜?，然后把它們拉直?/p>

然后我們識別它們，看看是否能找到亞洲蜜蜂的翅膀。

教授：你找到了多少？

格蘭特：到目前為止，我們的研究表明，亞洲蜜蜂還沒有進(jìn)入澳大利亞，這是一個很好的結(jié)果，比試圖尋找活蜜蜂作為引入昆蟲的證據(jù)要可靠得多。

教授：好吧，那太迷人了！

格蘭特，謝謝你的見解。

我希望你能啟發(fā)我們這里的一些學(xué)生進(jìn)行一些類似的實(shí)驗(yàn)。

Write ONE WORD ONLY for each answer.Looking for Asian honey bees

Birds called Rainbow Bee Eaters eat only and cough up small bits of skeleton and other products in a pellet.

Researchers go to the locations the bee eaters like to use for.

They collect the pellets and take them to a for analysis.

Hereis used to soften them,and the researchers look for the of Asian bees in the pellets.

The benefit of this research is that the result is more than searching for live Asian bees.

五、Honey Bees聽力答案解析

21.A原文中提到We discovered a few of them in Queensland once and eradicated them.的意思是我們曾在昆士蘭發(fā)現(xiàn)過亞洲蜜蜂，并且已經(jīng)完全消滅了它們。

22.B...but they are infested with mites...and which can seriously damage our home-grown bees...的意思是但是這些亞洲蜜蜂被大量的小蟲包圍，這些小蟲可以嚴(yán)重影響我們本土蜜蜂。而題干中的parasites的意思是寄生蟲，因而答案應(yīng)該選擇B。

23.C在in fact,as a matter of fact,actually等強(qiáng)烈轉(zhuǎn)折詞之后出現(xiàn)的詞組和句子是正確答案。

24.A原文We could lose a lot of money...的意思是我們會損失很多錢，和選項(xiàng)A the country’s economy would be affected（國家的經(jīng)濟(jì)將會受到影響）表達(dá)同樣的意思。

25.insects總結(jié)填空題的關(guān)鍵就是找好定位詞，此題的定位詞是專有名詞Rainbow Bee Eaters。找準(zhǔn)定位詞之后根據(jù)語法判斷出此題的答案應(yīng)該是名詞，那么出現(xiàn)在定位詞之后的句子中所包含的名詞只有insects。

26.feeding/eating原文中的Spot和題干中的locations都表示地點(diǎn)。

27.laboratory pellet是定位詞，另外，原文中的examine the contents.和題干中的analysis表達(dá)同樣的意思。

28.water原文...adding water to moisten them and make them softer的意思是加入水使這些東西變得潮濕并且更加柔軟。

29.wings Asian bee wings和the wings of Asian bees是語法上簡單的轉(zhuǎn)換。

30.reliable/accurate...it is a good result and much more reliable than trying to find live ones as evidence of introduced insects.的意思是這是一個很好的結(jié)果，并且比試圖去尋找活著的亞洲蜜蜂作為引進(jìn)昆蟲的證據(jù)更加可信。
