短文 2

Why does nature create patterns?

大自然为什么会形成各种图案？

The reason patterns often appear in nature is simple: the same basic physical or chemical processes occur in many pattern substances and organisms as they form.

自然界频繁出现图案的原因很简单：许多能够形成图案的物质与生物在成型时，都会发生相同的基础物理或化学反应。

Whether in plants and animals or rocks, foams and ice crystals, the intricate patterns that happen in nature come down to what’s happening at the level of atoms and molecules.

无论是动植物、岩石、泡沫还是冰晶，自然界复杂的图案归根结底都源于原子与分子层面的活动。

A pattern in nature is any regularly repeated arrangement of shapes or colors.

自然界的图案，指形状或色彩规律重复排布的任何结构。

Some of the most striking examples include the six-sided arrays of rocks at Giant’s Causeway in the United Kingdom and the colorful stripes and spots on tropical fish.

最鲜明的例子有英国巨人堤道上呈六边形排布的岩石，以及热带鱼身上色彩斑斓的条纹与斑点。

Patterns like these begin to form at a small scale when materials undergo processes like drying, freezing, wrinkling, diffusing, and reacting.

材料经历干燥、冻结、起皱、扩散、化学反应等过程时，这类图案会先在微观尺度开始形成。

Those changes then give rise to complex patterns at a larger scale that people can see.

这些变化继而形成肉眼可见的、更大尺度的复杂图案。

Imagine delicate frozen crystals on a window during winter.

试想冬日窗户上精致的冰花冰晶。

What creates that pattern?

是什么造就了这种图案？

When water freezes, its molecules begin clustering together.

水结冰时，水分子会聚集在一起。

Water molecules have a particular bent shape that causes them to stack into clusters as they freeze.

水分子拥有特殊的弯折形态，结冰时会堆叠聚拢成分子团。

As the cluster grows, many outside factors, including humidity and temperature, begin to affect its overall shape.

分子团不断变大的过程中，湿度、温度等诸多外界因素会开始影响它的整体形态。

If the water is freezing on a window, for example, random imperfections on the glass surface affect the stacking and create the larger pattern.

举例来说，倘若水在玻璃窗上结冰，玻璃表面随机存在的细微瑕疵会改变水分子堆叠方式，最终形成大面积冰花纹路。

But scientists do not always know the purpose of a pattern, or even if there is one.

但科学家并非总能弄清一种图案存在的作用，甚至无法确定它是否具备某种作用。

The molecular processes involved are simple enough that they might generate a pattern by coincidence.

相关的分子变化过程十分简单，因此图案的形成有可能只是偶然现象。

Questions 12 to 15 are based on the passage you have just heard.
