您要查找的是不是：
- The shape of a snow crystal may change from one form to another as the crystal passes through levels of air with different temperatures. 当他们通过不同温度的大气时,雪晶的形状会从一种形状变为另一种形状。
- By applying high voltage to a growing snow crystal in the lab, Libbrecht is able to analyze unique growth mechanisms, especially on very small scales. 而在较为温暖的气候中，比如纽约州或邻近地区，就不太会出现好看的结晶。近几年，我一直访问北部寒冷的地区，在那里等待下雪。目前正在安大略的北部。”

- Actually, the term snowflake refers to an individual snow crystal, while snow falling from the sky are called snowballs which include hundreds or even thousands of small snowflakes stuck together. 事实上,雪花一词是指个别的雪晶,而从天空降下来的雪称为雪球,它聚集了数百甚至数千个细小雪花黏在一起。
- When snow crystals stick together, they produce snowflakes. Snowflakes come in different sizes. 当雪晶粘在一起时,他们会形成雪花。雪花会有不同的大小。
- All snow crystals have six sides, but they grow in different shapes. The shape depends mainly on the temperature and water levels in the air. 所有的雪晶都有六个边,但是他们会长成不同的形状。形状主要是由温度和空气中的水量决定的。
- In their most basic form, snow crystals are hexagonal prisms like the sample, above, but other, more complex forms are famously possible. 雪花的最基本结构中，雪晶属于六角晶系，如上图样本。但其他更复杂的结构也是极为常见的。
- When melting snow crystals or raindrops fall through very cold air, they freeze to form small particles of ice, called sleet. 当融化的雪晶或雨滴落下时穿过非常冷的空气，它们会冰冻成很小的冰粒子，称作冰雨。
- Rime -- Super cooled tiny water droplets (typically in a fog), that quickly freeze onto whatever they hit. An example of this is the small droplets of rime on large snow crystals. 雪晶-独立的单个冰晶，一般为六重对称形状。雪晶由空气中的冷凝水蒸汽直接包裹着尘埃或者别的外来物质为核心凝华而成。

- He trudge three hour in the snow to get back home. 他在雪中跋涉三个钟点才回到家。
- Snow scattered unequally over the mountainside. 雪不均匀地散落在山腰上。
- This set of crystal wine cups is very expensive. 这套水晶玻璃酒杯非常昂贵。
- Bentley was so enraptured by what he saw that he went on to devote his life to photographing thousands of snow crystals, and did much to persuade the world that they are all different. 本特利对显微镜下看到的景象欣喜若狂，于是倾毕生的心血拍摄了成千上万种雪晶，并做了大量的工作说服世人雪花的形状都是不重样的。
- The snow has frozen hard on the road. 路上的雪已经冻得很硬了。
- I lost my crystal necklace at the party. 我在晚会上丢失了水晶项链。
- The compacted snow on the pavement turned to ice. 人行道上被踩实的雪已变成了冰。
- She made her meaning crystal clear. 她把她的意思解释得清清楚楚。
- Children love to ball snow up in their hands. 小孩子们喜欢将雪在手里做成球儿。
- Dark clouds are a sign of rain or snow. 乌云是雨或雪将至的预兆。
