　1.The World's Greatest Swordsman (n. 剑客, 击剑手) 　　At an exhibition of the world's best swordsman, the third-place(排名第三的) fencer(n.剑客，击剑者)took the stage. A fly was released, and with an arc(n.弧) of his sword(n.剑，刀) he cut the fly in half. The crowd cheered. Then the second-place man sliced(slice n.薄片vt.削) a fly into quarters. A hush fell in anticipation of the world's greatest swordsman. 　　His blade came down in a mighty arc - but the insect continued on its way! The crowd was aghast. The greatest swordsman had missed his target completely, yet he continued to smile. 　　"Why are you so happy?" someone yelled. "You missed!" 　　"Ah," replied the swordsman, "you weren't watching very carefully. They fly lives, yes - but he will never be a father." 　　stage [n.舞台 take the world stage登上舞台 　　exhibition ]n.展览(会)release ]vt./ n.释(排)放;放开 　　hush v.(使)安静下来 n.安静，寂静 　　anticipation n.预期;预料 in anticipation of 期待着 　　blade ]n.刀刃，刀片 mighty [a.强大的 　　insect ]n.昆虫，虫 aghast ]a.惊骇的
