听力原文： Robert Bruce was a famous Scottish general. In the early fourteenth century he tried to drive the English out of Scotland, but he was not successful because the English were too strong. Finally, Bruce had to run away and hide in a cave.
One day, he lay in his cave thinking of the sad state of Scotland. A spider began to make a web above his head. Simply to pass the time, Bruce broke the web. Immediately the spider began to make a new one. Six times Bruce broke the web and six times the spider made a new one. Bruce was surprised at this. He told himself that he would break the web a seventh time. If the spider made a new ones it would be a good lesson to him, for like the spider, he had been defeated six times. Bruce then broke the web. Again the spider made a new one.
From this simple fact, Bruce became encouraged. He again got an army together. This time he was successful and drove the English out of Scotland.
