中国药学家屠呦呦因发现青蒿素治疗疟疾新方法而获得2015年诺贝尔生理学或医学奖。这是中国本土培养的科学家首次获诺贝尔奖。

疟疾是威胁人类生命的一大顽疾，困扰了人类几千年。20世纪60年代末，治疗疟疾的常用药物——氯喹或奎宁的药效已经减弱，疟疾的发病率再次升高。为了找到新型抗疟药物，中国政府启动了研制治疗疟疾药物的“523项目”，中医研究院成立以屠呦呦为组长的科研组参加研究工作。在极为艰苦的条件下，屠呦呦小组与全国7个省市、30多个单位的科研人员协同合作，经过数百次试验、无数次失败，并从《肘后备急方》等传统中草药文献中获得灵感、汲取智慧，最终使用乙醚从青蒿中提取了疗效高的青蒿素，开创了治疗疟疾新方法，挽救了全球数百万人的生命。世界卫生组织将青蒿素和相关药剂列入其基本药品目录，以青蒿素为基础的复方药物已经成为疟疾的标准治疗药物。

屠呦呦说，获得诺贝尔生理学或医学奖，是中医中药走向世界的一项荣誉。它属于科研团队中的每一个人，属于中国科学家群体。用现代科学手段不断认识中医药，是我们一代代科研工作者的责任。

    Early in the morning, at noon, or in the evening in big cities and in the countryside, all over the United States, you can see Americans running—men and women, young and old. People run1 — along the beaches of California, 2 Central Park in New York, down quiet streets in small towns or at the gym. Some people even run in 3 living rooms.

    Running wasn't so popular in the past. In the 1960s, runners were mostly athletes and healthy strong people. When people saw a runner, they used4, "Hey, what's the hurry for?" or they might say to 5 , "Is he crazy?" At that time, women almost never ran. If they did, they might be laughed at. But today all these have6. Men and women of all 7 enjoy running.

    Doctors say many of the health problems in the United States 8these bad habits: eating too much, smoking cigarettes, and taking 9 exercise. Doctors tell us, "Eat less, don't smoke, and exercise more." Running is good exercise10 it helps build strong hearts and lungs. It also helps most people lose weight.
