Children like snow because they can play snowballs or make snowmen with snow. But do you know how snow is formed? Cold air is necessary to make snow. A cloud is just water vapor . It contains many tiny water drops. These water drops freeze below the freezing point of water. But absolutely pure water does not freeze by itself. Instead, the water drops need to stick to something else such as dust . Then water drops begin to freeze and other water drops stick to these new ice crystals . These ice crystals grow larger and finally turn into snowflakes . Each snowflake has six sides. It might contain up to 200 crystals. And each snowflake is different and beautiful.
-contain [kən'teɪn ] vt. 包含,容纳
-absolutely ['æbsəlu:tli ] adv. 绝对地,完全地

雪
孩子们喜欢雪,因为他们可以玩雪球、堆雪人。但你知道雪是怎么形成的吗?要形成雪,冷空气是必不可少的。一朵云其实就是一团水蒸气,其中包含许许多多细小的水珠。这些水珠在温度降到零下的时候会凝结。但完全纯净的水滴是没法凝结的,相反,它们需要吸附在别的东西上才行,比如微尘颗粒。然后,水珠开始凝结成冰晶,其他的水珠也会聚拢到这个冰晶上。冰晶越变越大,最后就会变成雪花。每一片雪花都是六边形的,一片雪花可能包含多达200个冰晶。每片雪花都各不相同,但每一片都非常美丽。
Falling Snow
Amy Lowell
The snow whispers around me
And my wooden clogs
Leave holes behind me in the snow.
But no one will pass this way
Seeking my footsteps,
And when the temple bell rings again
They will be covered and gone.
1919
飘雪
埃米·罗厄尔
雪在我耳边低语,
我的木屐
在我身后留下印痕。
谁也不打这路上来
追寻我的足迹,
当寺钟又敲响,这些脚印
就会盖没,就会消失。
1919

落雪
艾米·洛威尔
雪在我周围低声絮语,
木屐
在身后的雪地踩出一串小坑。
可没有人会经过这里
寻我的脚印,
当寺钟再次敲响
脚印会被掩埋消失。
