【美国国家地理】第一集：海洋是个百宝箱

　　英文版本

　　Do you know what our Earth looks like from space? Why is its main part covered in blue? Earth looks like a beautiful blue marble. Over 70 percent of its surface is the ocean. Scientists divide the ocean into five sections. From biggest to smallest, they are The Pacific, the Atlantic, the Indian, the Antarctic, and the Arctic Oceans. Oceans are deep and wide. The largest mammal in the ocean is the blue whale. It is big and heavy. It can grow up to 30 meters long, as long as two school buses. The adult whale can weigh 200 tons. About the weight of 15 school buses Some of the smallest animals also live in the ocean, such as…Zooplankton. We can only see them with a microscope. In the ocean, there are about one million species of animals. Now we’ve explored a small of part of it. Maybe you’ll be the next to discover a new species of fish. Well, young explorers, thanks for listening! See you next time.

　　中文版本

　　设想我们从宇宙中遥望地球，地球看上去像什么呢？为什么它的大部分都被蓝色所覆盖呢？地球看起来就像一颗美丽的蓝色弹珠。海洋面积占地球面积的70%。科学家们将海洋分成五个部分。从大到小，它们依次为:太平洋、大西洋、印度洋、南冰洋和北冰洋。海洋浩瀚无垠。超级大的哺乳动物—蓝鲸，就生活在这里。蓝鲸又大又重。一头成年的蓝鲸长达30米，堪比两辆校车的长度。它能长到重达200吨。如同15辆校车的重量。海洋中还有一些世界上特别小的动物，比如……浮游动物。只有借助显微镜才能发现它们。海洋还是100多万动物共同的家园。我们目前只是探索了其中的一部分。也许下个发现鱼类新物种的人就是你。
