20世纪30年代,一位年轻的旅人到法国的阿尔卑斯山一带探险。他来到一片广袤的荒地。那里荒凉、险恶、丑陋,是那种人们避之不及的地方。突然,旅人的脚步突然停了下来。他看见在广袤的荒地间,有位老人躬身背着一袋橡子,手持一根四英尺长的铁管。老人正用铁管在地里刨坑,再从袋中取出橡子投到坑里。后来,老人告诉旅人,“我种了十万多颗橡子,恐怕只有十分之一能成活。”老人 In the 1930s, a young traveler explored the French Alps. He came to a vast wasteland. There desolate, sinister, ugly, is that people can not avoid the place. Suddenly, the traveler’s foot stopped suddenly. He saw an old man bowing with a bag of acorns in the vast wasteland and holding a four-foot iron pipe. The elderly are using iron pipe in the ground planing pit, then remove the acorns from the bag into the pit. Later, the old man told the traveler, “I planted more than 100,000 acorns and I am afraid that only one-tenth will survive.”
