湖南省长沙市华益中学2023-2024学年九年级上学期第三次月考英语试题
Haman Bekele, now 14, moved to Virginia, the US when he was 4 years old. But he still cares about his birthplace: Ethiopia(埃塞俄比亚).
"Skin cancer(皮肤癌) is a big problem in developing countries," Bekele told USA Today. But it's expensive for people to treat it. That made Bekele feel sad. He wanted to find a better way. So Bekele learned about skin cancer. He learned that dendritic cells(树突细胞) help protect skin. Then he made skin cancer-treating soap with the cells. Doing it taught him how important it is not to give up, Bekele said. One big challenge was to make sure the soap didn't break into pieces. He tried many different ways. Finally, he succeeded.
"It was so difficult to get a bar of soap to not just melt immediately(立即融化掉)," Bekele said, adding that he tried many different ways. "Keeping trying is a very important part of the scientific process."
Bekele's invention won him 25,000 dollars (about 178,000 yuan) as prize money in the 2023 3M Young Scientist Challenge. It's a competition in the US that encourages kids to think of new ways to solve everyday problems. "I'm going to use this prize money to continue research within the science field," Bekele told NPR.
