"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 honorary-title (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 "sugar-coated 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 sugar-coated 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. "
① Gu Fangzhou himself. ② Gu Fangzhou's partners' kids.
③ Gu Fangzhou's parents. ④ Gu Fangzhou's son.
Juice tastes good. But is it wise and healthy to drink juice? We asked three experts for their ideas.
Bec Reynolds, a nutritionist(营养学家) Drinking water is the best choice. However, if you don't like it and cannot drink milk, then it's better to drink juice than to have drinks that are "worse," like soft drinks. Both juice and soft drinks are sugary, but juice often have some vitamins, so you'd better not drink them. It would be better to drink juice that is made from many different vegetables. Few children eat enough vegetables. But vegetables are very important for the growth of your body. |
David Manton, a ____ There are two main reasons for not drinking juice. First, the sugar in it feeds the bacteria(细菌)on your teeth. In Australia, nearly half of all six-year-olds have at least one hole in their teeth. Drinks like fruit juice are part of the reason for this. Second, the acid(酸) in many different fruit juices can destroy the hard outer coating of your teeth. Once it's gone, it can't grow back. |
Sandro Demaio, a doctor Fruits like oranges and apples have fiber(纤维素). Fiber is very important. First, it slows down our eating. Second, it makes us feel full for longer. And third, it helps prevent the sugars going into our blood. Then we have fewer chances of getting weight, which can lead to many health problems. When we tum apples into apple juice, we remove most of the fiber. Sometimes, even the vitamins are lost. What we don't lose, though, is the sugar. So try not to drink juice. |
