snowflakes怎么读

篇一：2014年职称英语 阅读理解(22) -Snowflakes

第二十二篇 Snowflakes

You’ve probably heard that no two snowflakes are alike. Of course, nobody has ever confirmed that statement by examining every one of the estim

ated one septillion snowflakes that drift to Earth each year. Still, Kenneth Libbrecht, a professor at the California Institute of Technology, is confident that the statement is true.

Snowflakes aren’t flaky, says Libbrecht. At their basic level, they’re crystalline. The lattice of every snowflake is six-sided in shape. The simplest snow crystals are six-sided flat plates and six-sided columns. Such crystals are common in places where the air is extremely cold and dry. Snow crystals acquire their special beauty when their simple six-sided symmetry blossoms. Under the right conditions, each of the six corners of a crystal sprouts what is called an arm. In a matter of minutes, the arms can become highly ornate and give the crystal a star like appearance.

Several factors in the environment affect the shape and growth rate of a snow crystal. One factor is humidity. Crystals grow faster and in more intricate shape as humidity increases. A second factor is air temperature. A snowflake is born when several molecules of water vapor in a cloud land on a speck of dust and freeze to form a simple crystal. As the young crystal bops around in the cloud, it passes through air pockets of varying temperatures. If the crystal passes through a pocket of air that is, say, -15 degrees Celsius, it will grow quickly and sprout six arms says Libbrecht. If the crystal is then tossed into a warmer pocket, one about -10C, the arms tips will stop growing quickly and form six-sided plates. If the crystal then drifts into an even warmer pocket of about -5C, its top and bottom will grow more quickly than its sides and become more column like in shape.

In the course of its life span, a snow-crystal might flutter through many warmer and colder pockets, acquiring a complicated and unique growth history. Such a history will give rise to a snowflake that is unlike any other. Each arm on the snowflake will look exactly like every other one, but the crystal itself will be one of a kind.

Using his cooling tanks, Libbrecht has learned how to create snow crystals of different shapes - plates, columns, needles, etc. Libbrecht has even refined his techniques so that he can make crystals that look highly similar to one another. Still, he lacks the control to manufacture identical twin snowflakes. A slight difference in humidity and temperature can upset the growth profileof a crystal.

答案与题解 :

1. A第一段的第一句说，没有两片雪花是同样的，昀后一句说 Libbrecht … is confident that the statement is true。这里的 statement指的就是“ no two snowflakes are alike”这句话。所以 A是正确选项。

2. D 第二段的第二句、第三句提供了答案。

3. A第三段第二句和第四句中提到了 One factor is humidity … A second factor is air temperature。所以 A是正确的答案。

4. A第二段描述雪花的形成过程时，用了好几个赞美的词语和句子，如 special beauty, six-sided symmetry blossoms，highly ornate等。所以，选项 A是恰当的。

5. C 昀后一段告诉我们， Libbrecht可以制造不同形状的雪花。他还改进了制造技术，能制造出极为相似的雪花，但还制造不出完全相同的雪花。所以 C是正确答案。

第二十二篇雪花

你可能听说过没有两片雪花是完全相同的。当然，没有人曾经检查过每年飘落到地球上的数以万亿计的雪花来证实这一说法。然而，加州理工大学的 Kenneth Libbrecht教授仍相信这一说法的真实性。

Libbrecht说，雪花并不是片状的。它们在基础阶段是结晶状的。每一片雪花的晶格部是六边形的。昀简单的雪晶体是六边的扁平碟状和六边的柱状。这种晶体在极寒极干的地方十分普遍。当这种简单的六边对称形状发生变化时，雪晶体就拥有了它们独特的美丽之处。在适当的条件下，结晶体的每个角都向外伸长，形成臂状物。在大约几分钟的时间内，这些臂状物变得非常华美，结晶体也变得像星星般闪闪发亮。 环境中的几个因素影响了雪晶体的形状及形成速度，其中之一是湿度。当湿度增加时，晶体变化得更快并且形成更为复杂的形状。另一个因素是气温。云里的水蒸气分子集结在尘埃上，冷凝形成简单的晶体，此时，雪花就诞生了。初形成的晶体在云里四处碰撞，穿过不同温度的空气团。 Libbrecht说，当这些晶体遇到大约 -15℃的空气团时，它们就会快速变化，长出六个臂状物。这时，如果晶体遇到一个温度更高的空气团（比如 -10℃），这些臂状物的尖端就会很快停止伸长，形成碟状的六边形。这时，如果遇到温度更高的空气团（比如 -5℃），它的顶部和底部会比两边更快地停止伸长，从而在形状上更像一个柱形。 在雪花的一生中，雪晶体可能遇到许多温度更高或更低的空气团，形成独特而又复杂的生长史，这使得雪花不尽相同。雪花的每一个臂状物行起来那十分相像。但晶体本身却是一片一种样子。

利用冷却槽 Libbrecht发现了如何制造各种形状的雪晶体，如碟状的、柱状的、针状的等。 Libbrecht还改

进了他的技术，使得晶体之间更加相像。然而，他仍然无法制造两片完全相同的雪花。湿度与温度的细微差别就会改变晶体的形成过程。

雪花(Snowflakes)

雪花

One day in winter holidays, it was cloudy. After a while, white snowflakes began to fall quietly.

Snowflakes, like feathers, fell everywhere quietly.

Snowflakes, as light as smoke, as white as silver, kissed the land tenderly.

Snowflakes, as naughty as butterflies sometimes fell on the roofs, sometimes on the branches, and sometimes fell on people's faces.

The trees in the street were covered with snow, just like in the white clothes.

The land was all wh!te. The walls in the gardens were full of snow, like a silver snake.

The snowflakes are the thick quilts for the wheat. The hardworking farmers will say happily, "There will be a big harvest next year. 雪花

寒假的一天，天空阴云密布，不一会儿，白色的雪花悄悄地落了下来。 雪花好像洁白的羽毛，悄悄地落着。

雪花宛如一缕青烟，一丝白银，亲吻着大地。

雪花又似嬉戏的蝴蝶，有时飘落屋顶，有时撒落枝头，有时纷飞到人们的脸上。

街上的树木被雪裹着，好像穿上了白色的衣襟。

大地一片白茫茫，花园的墙壁被洁雪覆盖着，恰似二条银色的暴蛇-。 雪花是冬小麦的厚厚棉被。勤劳的农民会由衷地赞叹："来年又是一个丰收年。"

第二部分 阅读理解（ 1 ）

Passage 1

Snowflakes look like white stars falling from the sky. But there have been times when snow has looked red, green, yellow, or black. There have been snowflakes of almost every color. Think how it would seem to have colored snowflakes coming down all around you.

Black snow fell in France one year. Another year grey snow fell in Japan.It was found that the snow was mixed with ashes. This made it look dark. Red snow had come down in other countries. When this happened, the snow was mixed with red dust.

Most snow looks white, but it is really the color of ice. Snow is ice that comes from snow cloud. Each snowflake begins with a small drop of frozen water. More water forms around this drop. The way the water freezes gives the snowflakes its shape.

No two snowflakes are ever just the same size or shape. Sometimes the snowflakes are broken when they come down. Otber snowflakes melt as they fall. All snowflakes are flat and have six sides, if they are not broken or melted. When the air is cold and dry，the falling snowflakes are small and hard. If the air is wet and warm, the snowflakes are big and soft.

Would you be surprised to see snowflakes as big as your head falling from the sky？It happened once in the United States. It could happen again.

雪花看起水像从天上掉下白色星星，但有好几次雪看起来是红的，绿的，或黑的，几乎有所有颜色的雪花。想想看似乎着了色的雪花在围绕着你飘落。

有一年法国覆盖了黑色大雪，有一年日本下了灰色大雪。检验雪发现雪混合了灰烬，这使它看起来发黑。红色的雪也已降临在其他国家，之所以这样是因为雪混合了红色尘土。 大多数雪看起来是白色的，但它其实是无色的。雪是由冰水转化的。每一个雪花是由下落的水结冻所构成的。水结冰时的方式赋予了雪花的形状。

没有两个雪花是永远一样的大小或形状。因为有的雪花在下落的时候就被破坏或是被融化。所有的雪花是平的，有六个面，如果它们没被损坏或融化。当空气寒冷干燥，下落的雪花小而且硬。如果空气温暖潮湿，雪花又大又软。

像头一样大的雪花从天上掉落会让你觉得惊讶吗？它发生在美国，并且可能再次发生。

Passage 2

A guide dog is a dog especially trained to guide a blind person. Dogs chosen for such training must show good disposition, intelligence, physical fitness and sense of responsibility.

At the age of fourteen months, a guide dog begins an intensive course that lasts three to five months. It becomes accustomed to the leather harness anl stiff leather handle it will wear when guiding its blind owner. The dog learns to watch the triffic and to cross the street safely. It also learns to obey such commands as "forward"，¨left¨，¨right" and “sit” and to disobey any command that might lead its owner into danger.

The most important part of the training course is a fourweek program in which the dog and its future owner learn to work together. However, many blind people are unsuited by personality to work with dogs. Only a tenth of the blind find a guide dog useful,

导盲犬训练是将一只狗经过特别训练后用于引导盲人。这种训练选择的狗必须表现出良好的性格、智力、体能和责任感。

在十四个月大，导盲犬的密集课程就开始了、为期二至五个月。它变得习惯于皮革吊带和僵硬的皮革处理时，它将服务于其盲目的主人。狗学会看交通和安全地过马路。它也学会了服从为“前进”， “左??， “右??和“坐??这样的命令和不服从任何将可能导致主人危险的命令。

培训课程最重要的部分是“fourweek”方案，其中狗和它的未来主人学会一起工作。然而，许多盲人的性格不适合与狗合作，只有十分之一的盲人找到一只对自己有用的导盲犬。

Passage 3

We are busy talking about and using the Internet，but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer network didn?t work well.If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It sbould be good enough to be used by many different computers. If part of the network was not working, information could be sent through anotber part. In this way computer network system would keep on working on the time.

At first, the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" in the Internet more convenient. Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.

The Internet has now become one of the most important parts of people's life.

我们都在谈论和使用互联网，但是有多少人知道网络的历史。

很多人得知网络建立于20世纪60年代时，都很吃惊。那时候电脑很大，也很贵。网络常常断线，如果网络中的一台电脑坏了，那整个网络都得停了。所以必须建立一个新的网络，这个网络应该能让很多台电脑使用，如果网络的一部分不能工作了，信息应该可以通过网络的另一部分传递出。通过这种方式，电脑网络系统可以及时的工作

一开始，只有政府使用网络，但在20世纪70年代，大学，医院和银行也被许可运行网络。然而电脑还是很昂贵，也不太好用，到90年代，电脑便宜了也好用了。科学家也丌发了软件，使网上冲浪更便利了。

Passage 5

These days, children often think of superheroes（超级英雄）as cute（漂亮的），cool and strong supermen. A poor, short and thin boy wearing glasses may not interest the kids today. Yet in less than 4 years, Harry Potter has taken the world by the storm. J.K.Rowling, the writer of Harry Potter, was a British single mother out of work and living on money given to her by the government. One day, when she was on a long train trip, she had the idea for this book. She wrote the first book of the seven in the cafe with her baby daughter sleeping beside her. Last year, the fans welcomed the birth of the fourth by lining outside the bookstores. Today these books are still popular among people. Harry Potter is something more than fantasy（幻想）．Rowling tries to tell the readers how things are not always what they seem to be. However, milhons of the fans don?t care about such a lesson. They would like to spend many sleepless nights waiting in line for the fifth, the sixth and the seventh to come. For them, surprising stories of the little boy are what they want.

Mr.White lived in a small village. His parents hadn't enough monev to send him to school. He had to help them to do something in the fields. But he didn?t like to live in the poor place. When he was sixteen, he got to the town and found work in a factory. Three years later he became tall and strong. So he was sent to Africa as a soldier. He stayed there for five years and got some money. Then he came back to England and bought a shop in a small town. No people in the town went to Africa except him. And he hoped they tbought he was a famous man and that they could respect him. The children often asked him to tell them some stories and his life in Africa.

One day a few children asked him to tell them something about the animals in Africa. He told them how he fought with the tigers and elephants. His stories surprised them all and some policemen and workers went to listen to him. It made him happier. Just a man who taught geography in a middle school passed there. He stopped to listen to him for a while and then said, "Could you please tell us a rare animal, sir?"

¨Certainly," said Mr. Turner. "One day I met a rhinoceros（犀牛）by a river---"

¨Please wait a minute, sir," said the man. "There aren?t any rhinoceros in Africa at alll" ¨It's rare just because there aren?t any！¨
