    Mr Jackson was blind from birth. He owned a fruit 1 on a very busy street. 2 he was visually disabled, he ran his business pretty handsomely. He could see nothing and he could only 3 the things within his reach. 4 he was able to handle it and was content with everything he had.

    One day his son came to him. He told Mr Jackson in 5 that he read in the newspaper of a 6 who could operate on his eyes and allow him to see. The father and son traveled to the doctor and paid for the 7.

    After the operation, the doctor asked Mr Jackson, “What is the first thing you are 8 to see when I take the bandages off?” He replied, “I really want to see my beautiful 9 on my stand!”

    The doctor and the son 10 Mr Jackson down to the busy street where his fruit stand had been located for so many years. The doctor 11 unwrapped the bandages 12 he could lay his eyes on the beautiful fruit! Mr Jackson was so full of 13 that he could finally see his life's work—taking care of his fruit! After a few hours of 14 his beautiful fruit stand, he looked down the street both ways and saw there were quite a few fruit stands in both directions. He looked 15 the street and saw many other fruit stands. He spent so much time looking at other people's fruit stands and 16 the competition. Soon his own business 17.

    From Mr Jackson's failure, we should know that everyone is a 18 individual with different fingerprints, DNA and thinking. What we need to do is just be ourselves and 19 everyone else to be who they are. Mind our own business and we should never be afraid of 20.

“青蒿素是传统中医药送给世界人民的礼物，……由此获奖是中国科学事业、中医中药走向世界的一个荣誉。”这是10月5日摘取2015年诺贝尔生理学或医学奖的中国女药学家屠呦呦向外界表达的获奖感言。

在上世纪60年代末，常用治疗疟疾的药物奎宁已经失效，但疟疾患者却在持续增加。屠呦呦团队与中国其他机构合作，将目光转向了传统中草药学，发现了植物青蒿中的提取物有疗效。历经380多次实验，青蒿提取物对疟疾的抑制率只有12％—40％。她重新翻查古代文献，东晋葛洪《肘后备急方》中的“青蒿一握，以水二升渍，绞取汁，尽服之”吸引了她的目光，很有可能在高温的情况下，青蒿的有效成分就被破坏掉了。她立即改用沸点较低的乙醚进行实验，经过艰苦卓绝的努力，从12%到100%，终于发现了青蒿素，全球数亿人因这种“中国神药”而受益。

提起艰苦岁月和付出的牺牲，屠呦呦一直没有抱怨，反倒是充满怀恋。从事科学是十分辛苦的，要有信仰有毅力，但也永远不要忽视环境的影响。科学研究充满着魅力也充满着偶然，有的科学家终其一生，只是证明了“此路不通”，而有些科学家则是幸运地站到了苹果树下。
