第二册第一单元关注猎豹(cheetahs in focus)猎豹有着在三秒内从零突然加速(sprint)到80千米/小时的惊人能力,它是世界上最快的陆地动物。

全速奔跑时,它的速度可达到接近100千米/小时,这时没有动物可以逃脱。

不幸的是,这种美丽腼腆的动物正处于濒临灭绝(becoming extinct)的境地。

为了帮助这种动物,国家地理杂志派了一支队伍深入到位于博茨瓦纳(Botswana)的莫雷米野生动物保护区(Moremi Wildlife Reserve)。

他们的目的是通过拍纪录片的形式来拯救这种华丽的(magnificent)动物。

南非的约翰内斯堡(Johannesburg)是最后一站,之后队伍就会进入非洲的野外开展他们的旅程。

这次探险的领队是Chris Johns,他是一个有着25年经验的摄影师。

Chris已经计划这次旅程很久了,陪伴他的是导游Dave Hamman。

Dave已经在南非生活大半生了,他对这里很熟悉,他的知识将会非常有用,因为他们要向北走800多公里进入博茨瓦纳和美丽的奥卡万戈三角洲(Okavango Delta)。

莫雷米野生动物保护区真是一个奇幻的(magic)的地方,似乎非洲所有的动物都在这里定居,坑坑洼洼的路上到处可见斑马(zebras)、水牛(buffaloes)和大象(elephants),就连长颈鹿(giraffe)也要出来露个面。

到了晚上,Dave和Chris 仍继续向前开,他们需要深入到野生动物区开展他们的任务。

第二天,他们早早起床,开始寻找猎豹。

不是说你一去到那里就可以看见猎豹的,这种机会很少,你要知道这种搜寻可能会花几天,甚至几个星期。

但是意想不到的事情发生了:一只雌性猎豹和她的五只幼崽。

Dave以前在灌木林的几年里,从未试过这么快遇到这么多的猎豹,这也是他一直期待的。

这一发现对Chris来说尤其有希望(promising)。

Chris :“猎豹是非洲保护问题的象征(metaphor)。

These rocks are formed from particles of mud and sand, typically when they settle to the bottom of a body of water. Fossils of organisms with hard body parts don’t appear in sedimentary rock old er than about 600 million years, but the Earth is estimated to be 4.6billion years old.To find the oldest life, paleontologists looked for it in the oldest sedimentary rock they could find. Sedimentaryrocks dating back to Earth’s earliest days are rar e. Some of the oldest known are about three and a half billion years old.StromatolitesIn these very old rocks, paleontologists have found something that looked familiar. Certain communities of microbes can form layered, rock-like mounds called stromatolites. Stromatolites grow in shallow bodies of water in many places around the world. In the 1980′s paleontologists found the remains of ancient stromatolites in 3.5 billion year old sedimentary rocks.Besides stromatolites, possible microscopic fossils have been found in rocks up to 3.5 billion years old. While the origin of these tiny structures is still intensely debated, many scientists are convinced that they are the remains of microorganisms. It appears that by at least 3.5 billion years ago, the oceans were teeming with life, and that the land was also colonized by microbes very early in Earth’s你有没有想过为什么科学家会认为地球已经有数十亿年的历史了?沉积化石理由之一便是研究人员在研究岩石特别是沉积岩中保存着的生物遗骸时找到了证据。

听力文章:关于计数的知识

听力文章:关于计数的知识

听力文章:关于计数的知识News That CountsA new number was discovered by a team of German mathematicians in January of this year. The previously unknown integer lies in the relatively unexplored region between the numbers 88,000,002,999 and 88,000,003,000. This unexpected integer has been provis ionally named “S,” for “Surprise,” until the mathematical community has determined its exact location and value.The existence of undiscovered whole numbers in the space between known integers has long been recognized as a possibility, according to theoretical mathematician and team leader Angela Zifferling at the Institute for Polynomial Advance in Töttingen, Germany.Crunching NumbersIt is largely because we are only used to counting up to a thousand or so in our everyday lives that we fail to notice the presence of so-called “inter-integral” numbers and other strange phenomena that lie in the incredibly distant regions of the number line.As Zifferling explains:“It’s as if you only made observations from here to the moon, and concluded that there isn’t anything much in outer space. We really have no idea what may exist in the remoter regions of the number line, because the simple fact is that the area beyond around one hundred billion is still almost completely unexplored.”If confirmed, the existence of number S would make calculations involving numbers in its region much more difficult, as it will probably be found to be exerting a kind of pressure on the whole numbers on either side of it in order to fit in. Mathematicians refer to this pressure as “integral crowding,” and say that it may increasingly be a problem as we move farther and farther from zero.mathematician n. 数学家integer n.

英语听力材料下载:格陵兰岛神奇的计数法How People In Greenland Learn How To Count
Kids learn to count on their fingers, because they’re so, well, handy! And it makes sense–most number systems
originally developed as people counted using their fingers.
The counting system of native Greenlanders not only uses
all ten fingers, but all ten toes as well! Here’s how it works. The Greenlandic word for the number seven translates as, “second hand, two.” That means you count five on the
first hand and add two from the second, to make seven. After you run out of fingers, go for the toes. Thirteen translates
as “first foot, three.” That means you add all ten fingers plus three toes.
The counting system we use has a base of ten. Larger numbers are simply multiples of ten. For example, ten tens make one hundred. We’re so used to our base ten system that
it may seem like the only possibility. But the Greenlandic number system has a base of twenty, and others have a base of five. Of all the number systems ever invented, five, ten, and twenty are the most common bases.
It’s no coincidence that these bases match the number of fingers on one hand, or two hands, or all of our fingers and toes. The connection between fingers and counting is so close that several languages have just one word that means both “hand” and the number five. Even in English, the word digit describes either a number or a finger. So if anyone teases
you for counting on your fingers, just tell them you find
your digits quite handy!
格陵兰岛人是怎样学会计数的?
小孩通过数手指来学习计数,因为这样确实非常方便。

由此,最
初的数字系统是从人们以手指计数发展而来也就变得合乎情理了。

古代格陵兰岛人的计数系统不但要用到十个手指,甚至连十个脚
趾都用上了!以下就是这种计数方式的工作原理。

格陵兰语中,数字7翻译出来就是“第二只手,两根手指。

”意思是说你数完第一只手的
五个手指,再加上第二只手的两根手指得到数字七。

如果手指不够用,那就再用脚趾。

数字13翻译出来是“第一只脚,三只脚趾。

”说明
你数完了所有十个手指,再数三个脚趾就得到数字十三。

我们使用的计数系统是十进制的。

较大的数字就是用10来倍乘。

比如,10个10就是100.我们非常习惯使用十进制计数,以至于认为
世上只有这个种计数系统。

但是格陵兰岛的计数系统是二十进制的,
也有一些地方采用五进制。

在所有发明的计数系统中,五进制、十进
制和二十进制是最为常见的。

这些计数的基数和我们的一只手的手指数、两只手的手指数,以
及所有的手指和脚趾的数目吻合并非巧合。

手指和计数之间的联系如
此紧密以至于很多语言里都只有一个词用来同时表示“手”和数字“五”。

甚至在英语里也有这样的情况,单词digit既可表示数字也
可表示手指。

所以,如果有人因为你用手指数数而取笑你的话,你只
需告诉他你觉得使用手指计算很方便就行了!。
