　　03-A. The Atlantic Ocean

　　The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americas from being discovered by the people of Europe.

　　Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to "the edge of the world." Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.

　　The Atlantic Ocean is only half as big as the Pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2, 000 miles (3,200 km) wide. This narrowest place is between the bulge of south America and the bulge of Africa.

　　Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands. Also, it is the world's saltiest ocean.

　　There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more water was brought to it by rivers. It would take the ocean about 4,000 years to dry up. On the average the water is a little more than two miles (3.2 km) deep, but in places it is much deeper. The deepest spot is near Puerto Rico. This "deep" 30, 246 feet - almost six miles (9.6 km).

　　One of the longest mountain ranges of the world rises the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range.

　　Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels the crew were afraid they would be becalmed here. Sometimes they were.

　　Ocean currents are sometime called "rivers in the sea." One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water. Another is the Labrador Current - cold water coming down from the Arctic. Ocean currents affect the climates of the lands near which they flow.

　　The Atlantic furnishes much food for the people on its shores. One of its most famous fishing regions, the Grand Banks, is near Newfoundland.

　　Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.

　　We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!

　　大西洋

　　大西洋是将欧洲和美洲分隔开的海洋之一。它使南北美洲长达几个世纪之久都未被人发现。

　　人们对大西洋有许多误解，这使得早期的海员不愿意远航驶入大西洋。一种想法是大西洋远抵“世界的边缘”，海员们担心他们会一直航行到地球边上掉落下去。另一个想法是在赤道处，大西洋的海水是滚烫的。

　　大西洋的面积只是太平洋的一半，但也非常辽阔。哥伦布穿越过的地方宽达4000多英里(6000公里)。即使最窄的地方宽度也有大约2000英里(3200公里)，这是一片位于南美洲最东端与非洲最西端之间的水域。

　　大西洋有两点非同寻常。其一是在如此辽阔的海洋里少有岛屿。另外，大西洋是世界上含盐量最高的海洋。

　　大西洋海水量很大，人们无法想像到底有多少水。但如果假设不再有降雨和河水注入，则需4000年大西洋才会干涸。大西洋平均水深有2英里(3.2公里)多一点，但有些地方要深得多。最深处在波多黎各岛附近，深达30246英尺——约6英里(9.6公里)。

　　世界上最长的山脉之一从大西洋海底隆起，这条山脉沿海底中部向南北延伸，几座山峰露出海面，形成岛屿。亚速尔群岛就是大西洋中部山脉露出水面的几座山峰。

　　佛罗里达州向东几百英里有一处海域叫马尾藻海，这里由于很少刮风，海面很平静。在使用帆船的时代，船员们担心他们会因无风而在此处无法航行。有时他们确实会遇到这种情况。

　　海流有时被称作“海洋中的河流”。大西洋有一条这种“河流”，叫做墨西哥湾流，这是一股暖水流；另外一条是拉布拉多海流——这是来自北冰洋的冷水流。洋流对流域附近大陆的气候有影响。

　　大西洋为两岸的人们提供了丰富的食物。大浅滩是最著名的捕鱼区之一，位于纽芬兰附近。

　　今天，大西洋是一条重要的航路，这条航路并不总是风平浪静，毫无危险。暴风雨会掠过洋面，堆起大浪。从北冰洋漂来的冰山也会横穿航道。

　　我们现在有快捷的旅行方式，这个大洋似乎也变小了。哥伦布横越大西洋用了两个多月的时间，一艘现代化快轮不到4天就可完成这一航程，而乘飞机从纽约到伦敦只用8小时，从南美到非洲只用4小时。

　　04-A. Improving Your Memory

　　Psychological research has focused on a number of basic principles that help memory: meaningfulness, organization, association, and visualization. It is useful to know how these principles work.

　　Meaningfulness affects memory at all levels. Information that does not make any sense to you is difficult to remember. There are several ways in which we can make material more meaningful. Many people, for instance, learn a rhyme to help them remember. Do you know the rhyme “Thirty days has September, April, June, and November…? ” It helps many people remember which months of the year have 30 days.

　　Organization also makes a difference in our ability to remember. How useful would a library be if the books were kept in random order? Material that is organized is better remembered than jumbled information. One example of organization is chunking. Chunking consists of grouping separate bits of information. For example, the number 4671363 is more easily remembered if it is chunked as 467,13,63. Categorizing is another means of organization. Suppose you are asked to remember the following list of words: man, bench, dog, desk, woman, horse, child, cat, chair. Many people will group the words into similar categories and remember them as follows: man, woman, child; cat, dog, horse; bench, chair, desk. Needless to say, the second list can be remembered more easily than the first one.

　　Association refers to taking the material we want to remember and relating it to something we remember accurately. In memorizing a number, you might try to associate it with familiar numbers or events. For example, the height of Mount Fuji in Japan - 12, 389 feet - might be remembered using the following associations: 12 is the number of months in the year, and 389 is the number of days in a year (365) added to the number of months twice (24).

　　The last principle is visualization. Research has shown striking improvements in many types of memory tasks when people are asked to visualize the items to be remembered. In one study, subjects in one group were asked to learn some words using imagery, while the second group used repetition to learn the words. Those using imagery remembered 80 to 90 percent of the words, compared with 30 to 40 percent of the words for those who memorized by repetition. Thus forming an integrated image with all the information placed in a single mental picture can help us to preserve a memory.

　　改善你的记忆力

　　心理研究集中在有助于记忆力的几个基本原则，即富有意义、组织、联想和想像。知道这些原则如何发挥作用是非常有益的。

　　富有意义从各个方面影响记记力。你很难记住对你毫无意义的信息，我们可以用几种办法使材料变得更有意义。例如，很多人学会用韵音来帮助他们记忆。你知道“九、四、六、十一有30天……”这首押韵诗吗?它帮助人们记住一年中哪些月份有30天。

　　信息的组织也对我们的记忆能力造成差异。图书馆的书如果陈列得杂乱无章对我们还会有什么帮助吗?组织过的材料比混杂的信息更容易记住。组织信息的一个例子就是组块。组块是将一个个单独的信息组织成信息块。例如，4671363这组数字如果被组块成467 13 63就更容易记住。分类是另一种组织方法。假定要求你记住一组词：男人、凳子、狗、书桌、女人、马、孩子、猫、椅子。很多人会将这些词分成相似种类的几组，即男人、女人、孩子；猫、狗、马；凳子、椅子、书桌。不用说第二种排列比第一种排列更容易记忆。

　　联想指将我们要记忆的材料和我们已准确记住的信息联系起来。在记忆数字时，可以将这一数字与我们所熟悉的数字或事件联系起来，例如，日本富士山的高度为12，389英尺，这一数字可以用下面的联想法记住：12是一年中的月份数，389是一年的天数(365)加月数的两倍(24)。

　　最后一个基本原则是想像。研究表明，如果人们把需要记忆的东西进行想像，各种记忆能力都会有显著的提高。在一项研究中，一组受试者被要求使用想像法学习一些生词，而另外一组用重复法学习生词。用想像法记忆单词的一组记住了80%～90%的生词，相比之下，用重复法记忆单词的一组只记住了30%～40%的生词。因此，将所有的信息放在一幅内心的图画里，从而形成一个整体形象，可以帮助我们保存记忆。
