Technology is the application (应用) of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has extended our life span via (通过) medical technology.
Will mankind continue to live longer and have a higher quality of life? In large measure the answer depends on technology and our ability to use it wisely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends upon research and development, and the latest statistics (统计) show that the United States is continuing to pump billions of dollars annually (每年) into such efforts. So while we are running out of some scarce resources (少的资源) we may well find technological substitutes (代用品) for many of them through our research programs.
Therefore, in the final analysis the three major factors of production (land, labor and capital) are all influenced by technology. When we need new skills, on techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.

技术是知识在生产上的应用.由于我们的先进的科技,我们才能够大大的提高我们的工作效率.新的机器和新的方法让我们在提高总体产量的同时缩短了时间,减少了开销.这些意味着更高的产量和更高标准的生活.对于我们大多数美国人来说,现代的科技被看成是我们能够拥有汽车和电视的远远.然而,现代科技业是我们拥有足够的食物,通过现代的机械化农场和动物繁殖技术,而且我们生命的跨度也提高了通过现代的医疗技术.
人们将会继续获得更长并且有一个高水平的生活质量吗?在大的方面这个答案将取决于科技和我们有智慧的使用它.如果我们继续取得进步就像过去的50里,那答案将是毫无疑问的会.先进的科学技术依赖于研究和发展,最新的统计显示美国持续的在以每年数以百亿的美元投入在这方面的努力上.所以当我们耗尽一些稀少的资源的时候,我们会通过我们的科研项目寻找一些科技上的替代品.
因此,总之对于生产的三个最主要的因素（土地,劳动,资本）都会受到科技的影响.当我们需要新的在医学方面的科技时,人门会发展新的技术区满足他们的需要,当一个设备被证明是功能有限或者是没有多大效果的时候,新的仪器将会被发明来取代他.科技就是对我们的需要作出回应然后来帮助我们来维持我们生活的标准.
大意是讲科技对人类特别是对生产的影响.
