南极——终年冰封的不毛之地
8．The Antarctic，a Dert of Ice All Year Round
The antarctic is actually a dert．It is the only continent on the earth without a river or a lake．
The antarctic is all ice all year round．The warmest temperature ever recorded there is zero，at the South Pole．Explorers ud to think that a place so cold would have a heavy snow－fall．But less than ten inches of snow falls each year．That is less than half an inch of water．Ten times that much moisture falls in parts of the Sahara．
The little snow that falls in Antarctica never melts．It continues to pile up deeper and deeper year after year and century after century．When the snow gets to be about eighty feet deep it is turned to ice by the weight of the snow above it．
8．南极——终年冰封的不毛之地
南极地区实际上是一片不毛之地，它是地球上唯一没有河流也没有湖泊的大陆。
南极地区终年冰封。那儿历史上的最高气温纪录是零度，那还是在南极点。探险家们过去总认为，如此寒冷的地方可能会有纷飞的大雪，但是，那儿每年的降雪却不足10英寸厚，还没有半英寸水多。撒哈拉沙漠一些地区的降雨量还是那儿的10倍呢！
降于南极洲的微量的雪从不融化，年复一年，一个世纪又一个世纪地越积越厚。当积雪达80英尺的时候，受上层重压的雪就会凝结成冰。

12．How the Falls of Iguassu Was Discovered
In 1542，Alvar Cabeza de Vaca and his small band of soldiers guided their boats down a jungle river．It was the Iguassu，which now marks the boundary between Brazil and Argentina．Never had the explorers en a river so beautiful．
At one point the men heard a strange rumble in the distance．It grew louder as they went on．Puzzled and afraid，they rounded a bend．Directly ahead of them the river vanished，plunging with a roar over the brink of a great chasm．
The men fought the swift current and managed to reach shore just in time to keep from being swept over the brink．Then they crept out on the wet rocks and looked into the churning caldron below．They had discovered the greatest waterfall that had ever been en by white men－the falls of Iguassu．
12．伊瓜苏瀑布是怎样被发现的
1542年，阿尔瓦·卡维萨·迪·威卡和他的一小队士兵驾船来到一条丛林河的下游，这就是伊瓜苏河——现在巴西和阿根廷之间的边界河。这些探险家们从未看到过这样美丽的河流。
这时，士兵们听到远处传来一种奇怪的隆隆声，越往前走，响声越大。士兵们感到迷惑和恐惧，于是转弯绕行。就在他们的正前方，那条河却越过一个巨大断层的边缘，咆哮着急降而下，消失不见了。
士兵们与激流搏斗，及时到达了岸边，从而免遭被冲刷出断层边缘的厄运。然后他们爬到湿漉漉的岩石上，看着下面那口奔突翻滚的“大锅”。他们终于发现了白人从未见过的最大瀑布——伊瓜苏瀑布。

10．加利福尼亚近海的海獭
生活在加利福尼亚近海的海獭，其取食方法很不寻常，它们潜入海底去寻找它们喜欢的甲壳动物。
当海獭把一只甲壳动物挟持到水面时，就背朝下浮在水面上，把甲壳动物抱在胸前，然后用牙把肉从壳中剔出。
海獭尤喜食长有坚壳的甲壳动物。当海獭把这样一只甲壳动物带到水面时，同时也带上来一块石头。它把石头放在胸前，用前爪抓住这只甲壳动物。它大幅度地摆动一下身体，对着石头猛击坚硬的甲壳，然后，取壳中肉就没有麻烦了。

9．The Small Black Ants，Nature's Clean—up Crew
The small black ants that we e running back and forth in the grass are the same ants th
at annoy us by coming to our picnics uninvited．They are not trying to make pests of them－lves，but are only doing the houkeeping job they were made for．They are nature's clean－upcrew．

When the beetle is dead，the ants carry it away to their underground burrows．The efficient ants leave nothing in the grass but the empty shell．
9．小黑蚁——大自然的清道夫
我们在草地上见到的那些爬来爬去的小黑蚁，与不邀自来，扰乱我们进行野餐的蚂蚁是同类。但是，它们并不是要搞破坏或捣乱，只不过是在履行管理家务的天职罢了。它们是一批大自然的'清道夫呢！
这些蚂蚁中的一员，在草地里侦察，发现了一只负伤的甲虫的踪迹。消息便以某种不可思议的方式传播开来。不久就出现了两只蚂蚁，接着又出现了几只。然后便有一打或更多的蚂蚁在甲虫的周围奔忙，最后，大量的蚂蚁会赶来置这只甲虫于死地。
甲虫死后，蚂蚁就把它抬到它们地下的洞穴中。草地上除了那只甲虫的空壳以外，办事利索的蚂蚁们什么也没给留下。
