课时作业
Ⅰ.阅读理解(每小题2.5分,共10分)
(2024·山东济南质检)A rising star from Virginia has secured the title of “America’s Top Young Scientist” for his groundbreaking creation—a bar of soap designed to battle against skin cancer.At just 14 years old, Heman Bekele emerged as the victor of the 2023 3M Young Scientist Challenge, standing out among the ten finalists with his innovative creation known as the Skin Cancer Treating Soap (SCTS).
Bekele’s brilliant concept centers on the development of a soap that is not only affordable, but also has the potential to reactivate the body’s natural defenders of the skin to stop skin cancer.In Bekele’s own words,“Curing cancer, one bar of soap at a time.” He always has endless passion for biology and technology, and the 3M Young Scientist Challenge just provided him with the perfect platform to display his ideas.Reflecting on his inspiration, Bekele shared that his childhood played a significant role in shaping his innovative thinking.Having witnessed people work tirelessly under the sun, he couldn’t help but wonder how many were aware of the risks associated with constant sun exposure.
“I wanted to make my idea not only scientifically exceptional but also accessible to a broad audience,”Bekele expressed during an interview with the media.He received invaluable guidance from Deborah Isabelle, a product engineering specialist, who connected him with other scientists to aid him in reaching his ambitious plans.
During his presentation, Bekele passionately expressed his vision of turning the soap into “a symbol of hope, accessibility, and a world where skin cancer treatment is within reach for all”.
Over the coming five years, Bekele longs to perfect his invention and establish a nonprofit organization devoted to distributing his innovative creation to more places including undeveloped communities, offering hope and a practical solution in the fight against skin cancer.
