     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 widely. 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 (稀有资源) we may well find technological

substitutes (代用品) for many of them through our re- search 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.
