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 (可供食用的) 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 (稀缺资源) 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. How does "technology" increase the amount of food available to us
A. By means of modem farming machinery and animal breeding techniques.
By means of modem computer science.
C. By means of producing more food.
D. By means of more new furniture.

"Get out of the classroom into a job," it said, and Ron obeyed. His father, supporting the decision, found a place for him in a supermarket. "You’re lucky, Ron," he said. "For every boy with a job these days, there’s a dozen without." So Ron joined the working world at twenty pounds a week. For a year he spent his days filling shelves with tins of food. By the end of that time he was looking back on his school-days as a time of great variety (多样性) and satisfaction. He searched for an interest in his work, with little success. One fine day instead of going to work Ron got a lift on a lorry going south. With nine pounds in his pocket, a full heart and a great longing for the sea, he set out to make a better way for himself. That evening, in Bournemouth, he had a sandwich and a drink in a café run by an elderly man and his wife. Before he had finished the sandwich, the woman had taken him on for the rest of the summer, at twenty pounds a week, a room upstairs and three meals a day. The ease and speed of it rather took Ron’s breath away. At quiet times Ron had to check the old man’s arithmetic in the records of the business. At the end of the season, he stayed on the coast.
