英语听力小短文走遍全世界03: Is Life Existing Somewhere Else Besides Earth? 地球之外有生命吗?(双语+mp3下载)

摘要:外星人是人类对地球以外智慧生物的统称。古今中外一直有关于“外星人”的假想,在各国史书中也有不少疑似“外星人”的记载,但现今人类还无法确定是否有外星生命,甚至是“外星人”的存在。

英语听力原文:

Since early times, people have been fascinated with the idea of life existing somewhere else besides earth. Until recently, scientists believed that life on other planets was just a hopeful dream. But now they are beginning to locate places where life could form.
很久以来,人们就被地球以外存在生命的观点强烈地吸引。直到近期,科学家们都坚信外星生命的想法只不过是个有希望的梦想。但是现在他们开始定位外星生命形成的位置。

In 1997, they saw evidence of planets near other stars like the sun. But scientists now think that life could be even nearer in our own solar system. One place scientists are studying very closely is Europa, a moon of Jupiter.
在1997年,他们在像太阳这类其他恒星的行星上发现了证据。可是,现在科学家认为外星生命甚至更接近我们,就存在于我们太阳系中。科学家们正在仔细研究的这个地方是欧罗巴,是木星的卫星。

Space probes have provided evidence that Europa has a large ocean under its surface. The probes have also made scientists think that under its surface Europa has a rocky core giving off volcanic heat. Water and heat from volcanic activity are two basic conditions needed for life to form.
太空探索提供的证据表明在欧罗巴的表层下蕴藏着一个巨大的海洋。太空探索还使科学家们相信在欧罗巴的表层下有一个岩层核心,释放出火山般的热量。火山活动的水和热是生命形式所需的两个基本条件。

A third is certain basic chemicals such as carbon, oxygen and nitrogen. Scientists believe there might be such chemicals lie at the bottom of Europa's ocean.They may have already created life or may be about to. You may wonder if light is also needed for life to form. Until recently, scientists thought that light was essential.
第三个条件是某些基本的化学元素,如:碳、氧、氮。科学家相信在欧罗巴的海底可能存在这些物质。它们或许已经创造了生命,也许将来会产生生命。你或许想知道光对于生命的形成是否必要。直到最近,他们都认为光是必须的。

But now, places have been found on earth that are in total blackness such as caves several miles beneath the surface. And bacteria, primitive forms of life have been seen there. So the lack of light in Europa's sub-surface ocean doesn't automatically rule out life forming.
但是,现在地球上完全黑暗的地方也有生命,如在地表下数公里的洞穴中。生命原始形式的细菌就存在于那儿。因此,在欧罗巴表层以下缺少阳光的海洋中无法自动排除生命存在的可能。
