Anton's Great Discovery Anton Van Leeuwenhoek was a Dutch cloth merchant. His life began to change after he got his first microscope in 1653. It was a very simple microscope. It had a lens in an upright stand. It could make small things look large. It was handy for looking closely at cloth. Soon, Anton felt a longing to build a more powerful microscope. He dreamed of using it to make an important scientific discovery. He wanted to become famous. Three decades later, he did. For many years, Anton experimented with microscopes and lenses. Eventually, he constructed a very powerful microscope. If he had sold the concept to others, it would have made him very rich. However, Anton refrained from surrendering his secret to anyone. Instead, he wanted to use it to become famous. So he used his secret microscope to study the natural world. One day, he was looking at saliva from his mouth with the microscope. In the saliva, he saw numerous tiny particles. Some of them were moving! He thought that the particles were tiny organisms. So he isolated them from each other and studied each one carefully. Then he classified them into different categories. Some were round. Others were long and had tails. All were alive. Anton was so excited. He knew he could become famous now. He was the first person to see these tiny organisms. So he drew diagrams of the organisms and sent them to a group of scientists in London. The scientists were sophisticated men who did not believe tiny, animate organisms could live in our mouths. Anton made a plea for them to come to Holland to see the organisms with their own eyes. The men took a ferry to Holland and met Anton. They performed a careful review of his work, and they conceded that he had made a worthwhile discovery. Anton Van Leeuwenhoek had discovered bacteria. After decades of hard work, he had become famous.

安东的伟大发现安东·范·列文虎克是一位荷兰布商。 1653年，他得到了第一台显微镜，从此他的生活开始改变。 这是一个非常简单的显微镜。 它有一个直立的镜头。 它可以让小东西看起来很大。 它便于近距离观察布料。 很快，安东就渴望制造一台更强大的显微镜。 他梦想着用它来做出一个重要的科学发现。 他想出名。 三十年后，他做到了。 安东用显微镜和镜头做了许多年的实验。 最后，他造出了一台非常强大的显微镜。 如果他把这个概念卖给别人，他就会非常富有。 然而，安东没有向任何人泄露他的秘密。 相反，他想用它来成名。 于是他用他的秘密显微镜来研究自然世界。 一天，他正在用显微镜观察自己嘴里的唾液。 在唾液中，他看到了许多微小的颗粒。 他们中的一些人在动！他认为这些粒子是微小的有机体。 所以他把它们分开，仔细研究每一个。 然后他把它们分成不同的类别。 有些是圆的。还有一些长着尾巴。 所有人都还活着。安东很兴奋。 他知道他现在可以成名了。 他是第一个看到这些微小有机体的人。 于是，他画了这些生物的图表，并把它们寄给了伦敦的一组科学家。 这些科学家都是老道的人，他们不相信微小的、有生命的有机体能在我们的嘴里生存。 安东请求他们来荷兰亲眼看看这些生物。 他们乘渡轮去了荷兰，遇到了安东。 他们对他的工作进行了仔细的审查，承认他有了一个有价值的发现。 安东·范·列文虎克发现了细菌。 经过几十年的努力，他已经出名了。
