答案

16. F 上文提及Heman在2023年获得了3M的青年科学家挑战赛奖项,此处顺承表示:2024年,他被《时代》杂志评为“年度儿童”。
17. D 由“在很多炎热国家,由于人们无法承担费用,得了皮肤癌,很少有人能幸存。”可知,此处对应表示:目前的皮肤癌治疗方法费用高昂。
18. E 由“我七岁生日前不久得到了我的第一套化学实验套装”可知,此处表示:那时我开始更多地思考如何为世界做些贡献。
19. B 下文表示结果“所以我必须找到一种方法让抗癌物质留在皮肤上”,此处表示原因:大多数肥皂在使用后会从皮肤上洗掉。
20. A 下文提及“然后还得获得美国食品药品监督管理局(FDA)的批准”,此处对应表示:这款肥皂还需要进行大量的测试。
