Cape Cod托福聽(tīng)力原文翻譯及問(wèn)題答案

一、Cape Cod托福聽(tīng)力原文：

NARRATOR:Listen to part of a lecture in an environmental conservation class.

FEMALE PROFESSOR:Next I want to talk about the collapse of the North American cod population. 

Let’s look at Cape Cod,in the northeastern United States…The area was named Cape Cod because there were so many cod fish in the waters just off its shores,so many that the first Europeans who fished there in the seventeenth century reported it was better than in Newfoundland,Canada.At the time,Newfoundland's cod fishery was so rich that people said it was possible just to lower a bucket in the water,pull it out,and it'd be full of cod.But Cape Cod was even better.So the fishing industry there did great until,after the 1940s.

uh,there were simply too many fishing vessels—sophisticated vessels—competing for fewer and fewer fish.In the 1940s,there were still about 400 million pounds of fish caught at Cape Cod every year.Just 50 years later,though—by the 1990s—commercial cod fishing there had become unprofitable;the annual catch had gone down to about five percent of its 1940s level.

And here's what's so fascinating.As more and more fishing vessels with better and better fishing technology were competing for cod,this competition was causing changes to the biology of the fish…and these changes were making it more and more difficult for the cod population to sustain itself.

FEMALE STUDENT:Changes to the biology of the fish?

FEMALE PROFESSOR:Well,if a cod fish could reproduce earlier than usual,it'd have a better chance of passing on its genes to the next generation before being caught,right?And sure enough,biologists noticed that around Cape Cod,the cod were beginning to mature at an earlier age than normal.

Prior to the population collapse,cod usually took about 8 to 10 years to fully mature,to start to reproduce,uh,and they lived around 40 years total.So cod had about 30 years of active reproductive life.

But now cod were beginning to reproduce at a younger age—at 3 to 4 years old.And they were living shorter lives because they were being caught,so they had fewer years within which to reproduce.

Additionally,even though some fish in the population were maturing at an earlier age,none was actually growing faster.No cod has a way of speeding up its rate of growth.So the younger reproductive age actually meant that smaller fish were reproducing.And,when you are a small cod reproducing,you produce fewer eggs than a large cod…the smaller cod simply don’t have the body mass to produce as many eggs.The overfishing pressure on the cod population was pushing the cod into an evolutionary corner—they were having a harder and harder time surviving.

MALE STUDENT:But what can be done to prevent other scenarios like this?I mean,obviously we need a better way to manage environmental resources.

FEMALE PROFESSOR:Well,what do you guys suggest?Carol?

MALE STUDENT:Hmm…uh,maybe privatize the resource? A private owner would want to manage the resource efficiently…in a sustainable way.

FEMALE PROFESSOR:OK,but the problem is,privatization doesn't necessarily result in better management of an environmental resource…Any ideas why it wouldn’t?

MALE STUDENT:Well,an individual owner might not properly assess the limits of the resource…so they could be just as prone to overexploiting that resource as a group,where lots of people have access to it.

FEMALE PROFESSOR:Yes.Well—like in the 1970s,when it was already clear the North American cod population was declining dramatically.The U.S.and Canada declared a 200-mile exclusive economic zone in the waters around Cape Cod.By declaring an exclusive economic zone,you see,these two countries were trying to extend their territorial waters.Basically,it was as if they were saying,“We’re the private owners—we own these waters,so we own the rights to the fish in them too.”Essentially,the two countries told fishing vessels—trawlers—from all other nations to get out of the cod-fishing area.

You'd think that'd be good news for the cod because there'd be less fishing.However,the U.S.and Canada wanted to expel foreign trawlers only in order to increase the numbers of their own fishing fleets.The total number of fishing trawlers actually increased.

Another possible solution—pass laws that regulate use of the resource.But for regulation to be effective,penalties for breaking the law have to be large enough to deter violators.

二、Cape Cod托福聽(tīng)力中文翻譯：

旁白：請(qǐng)聽(tīng)一節(jié)環(huán)境保護(hù)課上的講座。

女教授：接下來(lái)我想談?wù)劚泵厉L魚(yú)種群的崩潰；

讓我們看看美國(guó)東北部的鱈魚(yú)角…該地區(qū)被命名為鱈魚(yú)角，因?yàn)樵谄浜０陡浇乃蛑杏腥绱硕嗟镊L魚(yú)，以至于17世紀(jì)在那里捕魚(yú)的第一批歐洲人報(bào)告說(shuō)，這里比加拿大紐芬蘭更好。當(dāng)時(shí)，紐芬蘭的鱈魚(yú)漁場(chǎng)非常豐富，以至于人們說(shuō)，只要把一只水桶放到水中，把它拉出來(lái)，就會(huì)裝滿鱈魚(yú)。但科德角更好。因此，那里的漁業(yè)在20世紀(jì)40年代之后一直表現(xiàn)出色。

呃,漁船太多了,老練的漁船在爭(zhēng)奪越來(lái)越少的魚(yú)。在20世紀(jì)40年代，鱈魚(yú)角每年仍有大約4億磅的魚(yú)被捕獲。僅僅50年后，盡管到了20世紀(jì)90年代，那里的商業(yè)鱈魚(yú)捕撈變得無(wú)利可圖；年捕獲量已下降到20世紀(jì)40年代水平的5%左右。

這就是最吸引人的地方。隨著越來(lái)越多擁有更好捕魚(yú)技術(shù)的漁船爭(zhēng)奪鱈魚(yú)，這種競(jìng)爭(zhēng)導(dǎo)致了魚(yú)類(lèi)生物學(xué)的變化……這些變化使鱈魚(yú)種群越來(lái)越難以維持。

女學(xué)生：魚(yú)類(lèi)生物學(xué)的變化？

女教授：好吧，如果鱈魚(yú)能比平常更早繁殖，它在被捕獲之前就有更好的機(jī)會(huì)將其基因傳給下一代，對(duì)嗎？果不其然，生物學(xué)家注意到，在鱈魚(yú)角附近，鱈魚(yú)開(kāi)始比正常年齡更早成熟。

在種群崩潰之前，鱈魚(yú)通常需要8到10年才能完全成熟，開(kāi)始繁殖，呃，它們總共活了40年左右。所以鱈魚(yú)有大約30年的活躍繁殖壽命。

但現(xiàn)在鱈魚(yú)在3到4歲時(shí)開(kāi)始繁殖。它們的壽命更短，因?yàn)樗鼈儽徊东@，所以它們的繁殖期更短。

此外，盡管種群中的一些魚(yú)類(lèi)成熟較早，但實(shí)際上沒(méi)有一種魚(yú)類(lèi)生長(zhǎng)得更快。沒(méi)有一種鱈魚(yú)能加速其生長(zhǎng)速度。因此，較年輕的生殖年齡實(shí)際上意味著較小的魚(yú)類(lèi)正在繁殖。而且，當(dāng)你是一條小鱈魚(yú)繁殖時(shí)，你產(chǎn)生的卵比大鱈魚(yú)少……小鱈魚(yú)根本沒(méi)有產(chǎn)生那么多卵的體重。對(duì)鱈魚(yú)種群的過(guò)度捕撈壓力正將鱈魚(yú)推向進(jìn)化的角落，它們的生存越來(lái)越困難。

男學(xué)生：但是我們能做些什么來(lái)防止其他類(lèi)似的情況呢？我的意思是，顯然我們需要更好的方式來(lái)管理環(huán)境資源。

女教授：你們有什么建議嗎？頌歌

男學(xué)生：嗯……嗯，也許把資源私有化&nbsp；私人所有者希望以可持續(xù)的方式有效地管理資源。

女教授：好吧，但問(wèn)題是，私有化不一定會(huì)導(dǎo)致更好的環(huán)境資源管理……有什么想法為什么不會(huì)呢？

男學(xué)生：嗯，個(gè)體所有者可能無(wú)法正確評(píng)估資源的限制……因此他們可能會(huì)像一個(gè)群體一樣，過(guò)度開(kāi)發(fā)資源，因?yàn)楹芏嗳硕伎梢允褂谩?/p>

女教授：是的。就像上世紀(jì)70年代一樣，當(dāng)時(shí)北美鱈魚(yú)的數(shù)量已經(jīng)明顯下降。美國(guó)和加拿大宣布在科德角附近水域設(shè)立200英里專(zhuān)屬經(jīng)濟(jì)區(qū)。你看，通過(guò)宣布專(zhuān)屬經(jīng)濟(jì)區(qū)，這兩個(gè)國(guó)家試圖擴(kuò)大其領(lǐng)海。基本上，這就像他們?cè)谡f(shuō)，“我們是這些水域的私人所有者，所以我們也擁有這些水域中的魚(yú)的權(quán)利?！睆谋举|(zhì)上說(shuō)，兩國(guó)告訴所有其他國(guó)家的漁船和拖網(wǎng)漁船離開(kāi)鱈魚(yú)捕撈區(qū)。

你會(huì)認(rèn)為這對(duì)鱈魚(yú)來(lái)說(shuō)是個(gè)好消息，因?yàn)椴遏~(yú)會(huì)減少。然而，美國(guó)和加拿大想要驅(qū)逐外國(guó)拖網(wǎng)漁船，只是為了增加本國(guó)漁船隊(duì)的數(shù)量。拖網(wǎng)漁船的總數(shù)實(shí)際上有所增加。

另一個(gè)可能的解決方案是通過(guò)法律來(lái)規(guī)范資源的使用。但為了使監(jiān)管有效，對(duì)違法者的懲罰必須足夠大，以遏制違法者。
