The word horsepower was first use two hundred years ago. James Watt had made the world’s first widely used steam engine. He had no way of telling people exactly how powerful it was, for at that time there were no units for measuring power.
   Watt decided to find out how much work one strong horse could do in one minute. He called that unit one horsepower. With this unit he could measure the work his steam engine could do.
   He discovered that a horse lift a 3300-pound weight 10 feet in one minute. Because his engine did ten times as much as the horse, Watt called it a ten-horsepower engine.
选项
答案3300-pound
解析 该题既测试听清表示重量的词组的能力，也测试考生听清楚数字并迅速反应出来的能力。关键词是weight一词。在weight“重量”的前面常常可用数量修饰语。听写数字的方法是集中注意力。另外，单位词pound“磅”也可根据后面的名词weight“重量”进行判断。
