路易斯·巴斯德
Louis Pasteur was born in Dole, France on December 27, 1822.
路易斯·巴斯德于1822年12月27日出生于法国多尔。
His family was poor, and during his early education ,Pasteur was an ordinary student who enjoyed art and singing.
他家境贫寒，在他早期的教育中，巴斯德是一个喜欢艺术和唱歌的普通学生。
However, when Pasteur was exposed to science as a teenager, he knew he had found his career.
然而，在巴斯德十几岁时接触科学后，他知道自己找到了自己的事业。
In 1838, Pasteur went to college to become a science teacher. He then became a chemistry professor at the University of Strasbourg.
1838年，巴斯德成为了一名大学科学教师，后来成为了斯特拉斯堡大学的化学教授。
He got married in 1849 and had five children. However, three died young from typhoid fever（伤寒症）. It was the deaths of his children that drove Pasteur to investigate the infectious（传染的） disease in order to find a cure.
1849年，他结了婚，有了五个孩子。然而，其中三个孩子小时候就死于伤寒。正是孩子的离世驱使巴斯德去研究这种传染病，以找到治疗方法。
During Pasteur's time, people believed that bacteria（细菌） appeared due to "spontaneous generation（自然发生）." They thought that the bacteria just appeared out of nowhere.
在巴斯德生活的时期，人们认为细菌的出现是由于“自发产生”，他们认为细菌只是凭空出现的。
Pasteur carried out experiments to see if this was true. Through his experiments, he proved that germs were living things（生物） that came from other living things. They didn't just spontaneously（自发地） appear.
巴斯德做了实验来验证这是否正确。通过实验，他证明了细菌是来自其他生物的一种生物，它们并不是自发产生的。
This was a major discovery in the study of biology and earned Pasteur the title of Father of Germ Theory.
这是生物学研究中的一项重大发现，因此，巴斯德获得了“细菌理论之父”的称号。
As Pasteur learned more about bacteria, he began to think they may be the cause of diseases in humans.
随着巴斯德对细菌了解的越来越多，他开始认为细菌可能是引发人类疾病的起因。
When the French silk market was threatened by a disease to silkworms（蚕）, Pasteur decided to investigate. He discovered that this disease was caused by germs.

By killing them from the silkworm farms, he was able to cease the disease and save the French silk business.
他通过在养蚕场杀死细菌，阻止了病害的扩散，挽救了法国丝绸业。
Today Louis Pasteur is known as one of the most important scientists in history. His discoveries led to an understanding of bacteria and diseases that has helped save millions of lives.
今天，路易斯·巴斯德被认为是历史上最重要的科学家之一。他的发现推进了对细菌和疾病的理解，拯救了数百万人的生命。
