Physical labor[听力原文]We re now witnessing the emergence of an advanced economy based on information and knowledge. Physical labor, raw materials, and capital are no longer the key ingredients in the creation of wealth. Now, the vitalraw material in our economy is knowledge. Tomorrow s wealth depends on the development and exchange of knowledge. And individualsentering the workforce offer their knowledge, not their muscles. Knowledge workers get paid for their education and their ability to learn. Knowledge workers engage inmind work. They deal with symbols, words, figures and data.What does all this mean for you As a future knowledge worker, you can expect to be generating, processing, as well as exchanging information. Currently, three out of four jobs involve some form of mind work, and that number will increase sharply in the future. Management and employees alike will be making decisionsin such areas as product development, quality control and customer satisfaction.In the new world of work, you can look forward tobeing in constant training to acquire new skills that will help you keep up with improved technologies and procedures. You can also expect to be taking greater control of your career. Gone are the nine-to-five jobs, lifetime security, predictable promotions, and even the conventionalworkplace, as you are familiar with. Don t expect the companies will provide you with a clearly defined career path. And don t wait for someone to empower you. You have to empower yourself.[解析] 并列关系题。此处缺少名词作句子的主语，并与raw materials和capital并列。结合录音填入Physical labor，意为“劳动力”。
