Starting in the 1960s and continuing until the 1980s, sailors in Russia submarines patrolling the North Atlantic and Arctic Ocean would occasionally hear strange sounds. These underwater noise reminded the submarine crews of frog croaks, so they called the sound “quackers”(from the Russian word for frog sounds). The sources of the sound seemed to be moving with great speed and agility; however, the submarines’ sonar (a method of detecting objects underwater) was unable to detect any solid moving objects in the area. There are several theories about what might have caused the odd sounds.

  开始于20世纪60年代,一直持续到了20世界80年代,在北大西洋和北冰洋巡逻的俄罗斯潜水艇船员们偶尔会听见奇怪的声音。这些水下的声音使船员们想到了蛙叫,所以他们给这个声音取名叫“quackers”(来自于俄语,表示青蛙的叫声)。这些声音的来源似乎正在高速且灵敏的移动。然而,潜水艇的声纳(一种检测水下物体的方法)却不能在这个地区发现任何移动的物体。有几个理论关于到底是什么产生了这个奇怪的声音。

  The first theory suggests that the strange noises were actually the calls of male and female ocra whales during a courtship ritual. Orca whales are known to inhabit the areas where the submarines were picking up the bizarre noises. Orcas have been studied extensively, and the sounds they make when trying to attract a male are similar to those that the submarines were detecting.

  第一条理论说,这个奇怪的声音实上是某种雄性或雌性食人鲸在求偶中的叫声。所据人们所知,食人鲸生活在潜水艇发现奇怪声音的地区。人们对已经很广泛的研究了这种鲸鱼,而且他们吸引配偶所发出声音和潜水艇所发现的声音是很类似的。

  A second idea is that the sounds were caused by giant squid. Giant squids are giant marine invertebrates that live deep in the ocean and prey on large fish. They are difficult to detect by sonar because they have soft bodies with no skeleton. Not much is known about giant squid behavior, but their complex brains suggest they are intelligent animals. It is possible they have the ability to emit sound, and perhaps they approached the submarines out of curiosity.

  第二种想法是这种声音是由巨型乌贼所发现的。巨型乌贼是大型的海洋无脊椎动物,生活在海洋深处,吃大型的鱼类。巨型乌贼很难被声纳发现因为它们有柔软的身体而且没有骨骼。虽然人们并不太了解巨型乌贼的行为,但是它们复杂的大脑表明它们是有智商的动物。很有可能他们有能力发现声音,也许它们因为好奇接近潜水艇。

  A third theory suggests the Russian were picking up strange sounds from some military technology, like another country’s submarines that were secretly patrolling the area. Perhaps the foreign submarines did not register on sonar because they were using a kind of technology specifically designed to make the undetectable by sonar. The strange froglike sounds may have been emitted by the foreign submarines unintentionally.

  第三种理论说俄罗斯般员听到的奇怪声音是军事科技,比如别国在此区域秘密巡逻的潜水艇。也许别国的潜水艇没被声纳发现,是因为它们在使用一种特殊的技术,使得它们不能被声纳发现。奇怪的蛙叫般的声音有可能是别国潜水艇无意发现的。


听力原文

Quackers are certainly a very strange phenomenon. Experts still debate what the source of the sound was. No one can be sure exactly what caused them. But these experts cite certain problems with all of the theories that you just read about. Here are a few of the arguments that they make.

  “蛙叫声”肯定是奇怪的现像。专家还在争论此声音的来源是什么,但没有人可以确定。但是专家们表达了很多问题对于刚才你所读的理论。下面是他们所说的争论。

  First, the idea that the sounds were caused by Ocra whales seems plausible at first, but is ultimately highly unlikely. It’s true there are Orca populations in the general areas that the Russian submarines were patrolling. But Ocra whales mostly live near the surface of the water. The submarines typically remained deep in the ocean and should not have been able to hear the whale sounds from near the surface. Also the Ocra whales would have been detected by the Russian sonar if they were nearby.

  首先,食人鲸鱼发出这个奇怪的声音,开始听起来似乎有道理,但实际并不是。确实,在俄罗斯巡逻的地区有食人鲸,但是食人鲸多生活在水表面。潜水艇在海洋深处并不会听见表面鲸鱼的声音。而且,如果食人鲸接近潜水艇,声纳会发现他们。

  Giant squid may be a better candidate but one critical fact speaks against this squid theory as well. Russian submarines first detected the quackers sounds in the 1960s and reports of them continued for about two decades. But the sounds disappeared entirely by the 1980s. However, as far as we know, squid have always lived in the ocean where the submarines were patrolling and continue to live there today. If these were squid sound, there would be no reason to suddenly start hearing them in one decade and then suddenly stop hearing them twenty years later.

  巨型乌贼也许是更好的备选,但是有明显的事实与此相驳。俄罗斯的潜水艇起初发现蛙叫声在20世纪60年代,持续大约20年,到20世纪80年代声音完全消失。然而,据我们所知,巨型乌贼一直住在潜水艇巡逻的地方,直至今天。如果是巨型乌贼发出的声音,没有理由去解释突然听见叫声然后又突然在20年后叫声消失。

  Third, the idea that the quackers were caused by a secret submarine from another country does not hold up. The sources of the sounds appear to move around and change direction very quickly. Submarines cannot move or change direction that quickly. Also all submarines make some engine noise. But no such noise accompanied the quackers. Even today, we don’t have the technology to build submarines that are that fast and have engines that are that silent.

  第三,蛙叫声来自别国潜水艇的想法也是站不住脚的。奇怪声音的来源移动的很快,改变方向也很快。潜水艇不能移动转向如此的快。此外,所有的潜水艇都会发现引擎的声音,而且没有并引擎的声音随着蛙叫声。即使在今天,我们也没有这样的技术去修建移动如此之快而且如此安静的潜水艇。


例文:

The passage mentions three theories to explain the cause of the strange sound detected by the Russian sailors. However, the speaker insists these three theories are not convincing.

  First, the passage states the sound was caused by the ocra whales when they were attracting a mate. Yet, the speaker claims since the whales live at the surface of the ocean, they could not be heard by the submarine which was deep in the ocean. Also, if the whales approached the submarine, they would be detected by the sonar.

  Second, the passage expresses the sound was from the giant squids. It is studied that the squids were intelligent to emit sound. Because they were invertebrates, they could not detected by the sonar. Nevertheless, the speaker reckons the sound stated at 1960s and stopped at 1980s. The squids live at that area even today, so the squids theory is not plausible.

  Third, the passage points out the sound was emitted by submarines from another country, using a special technology which made it undetected by sonar. Conversely, the speaker says even today, we do not have the technology to make the submarines move so fast and the engines so silent.
