徐立平是中国航天科技集团公司高级技师，一直为导弹固体燃料发动机的火药进行微整形。

    在火药上动刀，稍有不慎蹭出火花，就可能引起燃燒爆炸。目前，火药整形在全世界都是一个难题，无法完全用机器代替。下刀的力道，完全要靠工人自己判断，药面精度是否合格，直接决定导弹的精准射程。0.5毫米是固体发动机药面精度允许的最大误差，而经徐立平之手雕刻出的火药药面误差不超过0.2毫米，堪称完美。为了杜绝安全隐患，徐立平自己设计发明了20多种药面整形刀具，有两种获得国家专利。由于长年一个姿势雕刻火药，以及火药中毒后遗症，徐立平的身体变得向一边倾斜，头发也掉了大半。28年来，他冒着巨大的危险雕刻火药，被人们誉为“大国工匠”。

   George liked flying a plane. Once he bought a small plane and learned how to fly it. He soon became so good that he could make his plane do all kinds of tricks（技巧）.
   George had a friend. His name was Peter. One day George said to his friend, “ Peter, would you like to have a trip in my plane?” Peter thought, “ I’ve traveled in a big plane several times, but I’ve never been in a small one, so I’ll go.”
   They went up, and George flew around for half an hour and did all kinds of tricks in a shaken voice（颤抖的声音）, “ Well, George, thank you very much for these two trips in your plane.”
   George was very surprised and asked, “ Two trips? ”
   “Yes, my first and my last.” Answered Peter.
