“I spent my whole life doing one thing，” Gu Fangzhou once said. Known as “the father of sugar pills(糖丸)”， Gu passed away on January 2， 2019. Eight months later， he received a national honorarytitle(荣誉称号) “the People's Scientist” for his polio(脊髓灰质炎) research.
Gu Fangzhou， a famous medical scientist， was born in June，1926. Gu's family faced a difficult time with the sudden death of his father. He studied hard and finally entered Peking University as a medical student in 1944. After graduation， Gu made the decision to work to help improve public health.
In 1955， polio broke out in Nantong，Jiangsu Province. It paralyzed(使瘫痪) 1，680 people，mostly children aged below seven. It spread to neighboring areas and resulted in 466 deaths. Gu was asked to lead polio research in 1957. “At that time the only way to prevent polio was to invent a vaccine(疫苗)，” said Gu.
In 1959 Gu succeeded in developing the first polio live vaccine. Later， he developed the “sugarcoated pill” vaccine in the early 1960s. It not only tasted better but was more affordable and easier to keep. To test the vaccine， Gu tried the vaccine in person and later his one-month-old son was vaccinated. This inspired his team to vaccinate their kids. They became the first group of people in China to try a polio vaccine. “If we don't believe in what we produce，how can others believe in it？” said Gu.
Gradually，the sugarcoated polio vaccine was made available in China. It saved millions of people，especially kids，from being disabled. In 2000，the World Health Organization (WHO) announced that China was already a polio-free country. “We feel satisfied. I can tell people that I tried my best， and your kids will no longer get polio，” said Gu. “That's all we hoped for.”

My Favorite Traditional Chinese Invention
Good morning， everyone！
I am very happy to be here to make a speech today. The topic of my speech is my favorite traditional Chinese inventions.Sky lanterns are my favorite traditional Chinese art form，for they are colorful and beautiful.
Sky lanterns are made of bamboo or metal covered by cloth or paper with pictures of different characters from Chinese fairy tales. On the nights of the Lantern Festival and other celebrations，lanterns of different shapes are lit，and they slowly rise into the air like small hotair balloons. They are regarded as symbols of happiness and good wishes.
According to Chinese history， sky lanterns were first invented by Zhuge Kongming， and they're still popular. They remind us that with the development of society， culture keeps changing， but something will remain unchanged.
We should protect and pass down traditional Chinese culture.
That's all. Thank you！
