练习材料：
As the man tried to swing the speed-boat round, the steering-wheel came away in his hands. He waved desperately to his companion, who had been water-skiing for the last fifteen minutes. Both men had hardly had time to realize what was happening when they were thrown violent1y into the sea. The speed-boat had struck a buoy, but it continued to move very quickly across the water. Both men had just begun to swim towards the shore. when they noticed with dismay that the speed-boat was moving in a circle. It now came straight towards them at tremendous speed. In less than a minute, it roared past them only a few feet away. After it had passed, they swam on as quickly as they could because they knew that the boat would soon return. They had just had enough time to swim out of danger when the boat again completed a circle. On this occasion, however, it had slowed down considerably. The petrol had nearly all been used up. Before long, the noise dropped completely and the boat began to drift gently across the water.

练习感悟：
今天终于结束考试了！还好自己比较幸运，抽到的题目不算难，讲的还可以，就是考试前心理压力太大了，总觉得自己没准备好，所以很遭罪。
还是那句话，不要打无准备之仗。今天考完试有点得意忘形了，打游戏打了一个多小时，看综艺也看了一个多小时，作业留到最后才做。
现在自己的时间慢慢多了起来，要好好的开始看看书了。希望自己不要白遭罪，要学到经验教训，下次要改进，不然自己失眠的那些夜晚，紧张的那种煎熬，全白费了。就算吃亏，也要有价值。
