He watched snowflakes(雪花)on his glove, on the vast farm fields, and on the dark metal handle of the barn(谷仓) door. He said snow was the blessings of Nature. However, he could not share snowflakes because he could not save them. Later, when his mother gave him an old microscope,he mainly used it to look at snow. While kids of his neighbors chased hens and had snowball fights, Willie was catching snowflakes. Day after stormy day he studied the icy crystals(冰晶). Their delicate patterns were even more beautiful than he had imagined.Willie decided he must find a way to save snowflakes so others could see their wonderful designs.For three winters he tried drawing snow crystals.They always melted in the black tray(托盘) that he used to catch them before he could finish the drawings. When he was sixteen, Willie read of a camera with its own microscope. "If I had that camera I could photograph snowflakes,” he told his mother. Willie's mother knew that he would not be happy until he could share what he had seen. “Spending time on snow is just foolishness,” his mother said. Still, she loved his son. When Willie was seventeen his parents spent their savings and bought the camera.It cost as much as ten cows.Willie was sure it was the best of all cameras. Even so,his first pictures were failures—no better than shadows.Yet he would not quit. Mistake by mistake, snowflake by snowflake, Willie worked through every storm. Winter ended, the snow melted, and he had no good pictures.He waited for another season of snow. One day, in the second winter,he tried a new experiment. And it worked! Willie had figured out how to photograph snowflakes! "Now everyone can see the great beauty in a tiny crystal," he said. Nevertheless, in those days no one cared.... Despite the new-found fame, Snowflake Bentley simply made up his mind to produce a perfect photo.... No two snowflakes are alike.But you might not know the man who discovered it. Actually, it can be traced back to Wilson Bentley, a farmer from Vermont,the USA, who in 1885 became the first person to successfully photograph an individual snow crystal —the ice that makes up snowflakes. After years of trial and error,Bentley was able to capture the intricate details of snow crystals by using a compound microscope attached to his bellows camera.He went on to photograph more than 5,000 of these "ice flowers" during his lifetime — never finding any duplicates — and the images still shine to this day. 故事解读 在那个人们只是农耕土种、饲养家畜的时代，美国佛蒙特州的人们对自然现象的美丽和奥秘并不感兴趣，更不用说去欣赏那些微不足道的雪花了。然而，对于威利·本特利来说，雪花的美丽和独特性却是无 ... ...
