11、极洲:最后(一块被发现)的大陆南极洲是地球上最冷的地方,同时也是最干燥的地方。南极洲年降雨量几乎为零,严格来说该区域就是一片荒漠。南极洲覆盖了南极圈周围约1 400万平方公里的面积,是世界第五大洲。一座高耸的山脉横穿南极洲,从东到西将南极洲分成两半。南极洲也有火山,但不活跃。世界上90%的冰都在南极洲,当然南极洲的大部分(70%)淡水也都处于一种冰冻状态。南极洲98%的地表永久地被冰覆盖。冰层平均厚度为2 000米,但某些地方厚度可达5 000米。受地球重力影响,会有暴风从极地吹向海岸,同时也有其他方向吹来的风。很难想象地球上还有比南极洲条件更为恶劣的地方了。助读讲解With annual r
12、ainfall close to zero为“with宾语形容词(短语)”构成的with复合结构,在此处作原因状语。Covering about .the South Pole为现在分词短语作状语。cutting the continent in two为现在分词短语作结果状语。driven by gravity为过去分词短语作后置定语。Yet Antarctica is full of wildlife, which has adapted to its extreme conditions.There are different types of penguins, flying bird
13、s, seals, and whales.But the long Antarctic winter night, which lasts for 182 days (the longest period of continuous darkness on earth), as well as the extreme cold and lack of rainfall, means that few types of plants can survive there.Only two types of flowering plants are found, whilethere are no
14、trees on the large continent.The rest of the plants are made up of mosses(苔藓), algae(藻类) and lichen(地衣)Some forms of algae have adapted(适应) to grow on ice.但南极洲仍然栖息着很多野生生物,它们已经适应了那里极其恶劣的条件。这里有不同种类的企鹅、飞禽、海豹以及鲸鱼。但是南极洲冬天的夜晚长达182天(地球上持续时间最长的黑暗时期),气候极度寒冷,降水量极少,这意味着很少有植物能够在那里生存。这里仅发现了两种开花类植物,而这片大陆上什么树都没有。其
15、他的植物也就是一些苔藓、藻类以及地衣。有些藻类已经适应了在冰上生长。助读讲解此处which引导非限制性定语从句,修饰先行词wildlife。此处while意为“而,然而”,作并列连词,表示对比。Most of the ice has been there for thousands of years.As a result, it has become a window on the past, and can give researchers lots of useful information.Gases and minerals, in the form of volcanic dust

17、ic rocks are dark in colour, they stand out against the white background and are easy to identify and collect.南极洲大部分的冰已经有几千年历史了。因此,它已经变成人们了解过去的窗口,可为研究者提供大量有用的信息。这些以火山灰的形式封冻进冰层里的气体和矿物质可以告诉我们很多关于远古时期全球气候的状况。南极洲的岩石对于研究来说也很重要。它们大部分是来自外太空的陨石。其中有一块叫作“外星”的岩石,或许能够证明地球以外生命的存在。南极洲的大多数岩石是深色的,它们在白色冰雪的映衬下格外显眼,也就
18、易于识别和搜集。助读讲解trapped in the ice为过去分词短语作后置定语,相当于一个限制性定语从句。此处what引导的宾语从句作介词about的宾语。known as the “Alien” rock为过去分词短语作后置定语,相当于一个非限制性定语从句。此处since引导原因状语从句。Antarctica was the last continent to be discovered.But more than two thousand years ago Greek geographers believed that there was a large land mass in

21、d Amundsen.南极洲是最后一个被发现的大陆。但是两千多年以前,古希腊的地理学家就相信地球南边会有一大块陆地来与北边的陆地保持平衡。他们称之为AntiArktikos或者Antarctica,意为“与北极相反的”。在15世纪欧洲人发现了美洲以后,大探险时代也随之开始了。然而,到达南极洲的步伐却始终非常慢。直到18世纪末,英国探险家詹姆斯库克才穿越了南极圈,但他却从未发现任何陆地。后来到了1895年,一个叫卡斯腾博克格雷温克的挪威人成为第一个踏上南极大陆的人。奔赴南极点的竞赛开始了。最终一名挪威人罗尔德阿蒙森于1911年12月11日到达南极。助读讲解to be discovered为动词不
