Blue whale numbers increase 南喬治亞島藍(lán)鯨數(shù)量有所增長
科學(xué)家們稱，他們在亞南極地區(qū)的英屬南喬治亞島的沿海水域看到了數(shù)量驚人的藍(lán)鯨。他們在歷時23天的調(diào)查中統(tǒng)計了55頭藍(lán)鯨，這是自商業(yè)捕鯨活動結(jié)束后，幾十年來前所未有的。
Whale experts have described the number of sightings as astonishing and say it's a positive sign that Antarctic Blues are making a solid recovery from their catastrophic collapse.
鯨魚專家們稱看到這么多鯨魚令人震驚，并表示這是一個積極的跡象，表明了南極藍(lán)鯨正從災(zāi)難性的毀滅中穩(wěn)步恢復(fù)。
When the whaling industry set up business in South Georgia in the early 1900s, it’s estimated there might have been nearly a quarter of a million of these majestic animals in the Southern Ocean. But within just a few decades, butchery on an industrial scale had reduced their numbers to a few hundred.
20世紀(jì)初，當(dāng)捕鯨業(yè)在南喬治亞開展業(yè)務(wù)時，南冰洋中估計有近25萬頭這種大型動物。但在短短幾十年里，大規(guī)模的殘殺活動使它們的數(shù)量減少到了幾百頭。
South Georgia's waters teem with the shrimp-like krill that whales love to eat, so Blues really ought to be returning to this productive feeding ground, and after 50 years of protection this seems finally to be the case. The last assessment of Antarctic Blue whale numbers was done in 1997 and estimated the abundance at just over 2,000. The next assessment will come out in a couple of years and may indicate that there are now up to 10,000.
南喬治亞的水域生產(chǎn)像磷蝦等鯨魚愛吃的蝦類，所以藍(lán)鯨確實應(yīng)該回到這片物產(chǎn)豐富的覓食地。經(jīng)過50年的保護，這似乎終于成為現(xiàn)實。上一次對南極藍(lán)鯨的評估是在1997年進(jìn)行的，當(dāng)時估計的數(shù)量剛剛超過2000頭。下一次的評估數(shù)量將在幾年后公布，可能會顯示藍(lán)鯨的數(shù)量近萬。

答案
1. Which industry led to the decline in the number of blue whales?
The whaling industry led to butchery on an industrial scale and reduced the numbers of blue whales.
2. What has caused experts to say the recovery of blue whale numbers is a positive sign?
Whale experts have described the number of sightings as astonishing and say it's a positive sign that Antarctic Blues are making a solid recovery from their catastrophic collapse.
3. Other than blue whales, what else can be found in the waters around South Georgia?
South Georgia's waters teem with the shrimp-like krill that whales love to eat.
4. True or false? The next assessment will probably show that the number of blue whales has increased.
True.The next assessment will come out in a couple of years and may indicate that there are now up to 10,000 blue whales – so an increase.
