Unit 6;Text A: Engineering;[1] Engineering is the profession that puts scientific knowledge to practical use. Engineers use principles of science to design structures, machines, and products of all kinds. They look for better ways to use existing resources and often develop new materials. Engineers have had a direct role in the creation of most of modern technology—the tools, materials, techniques, and power sources that make our lives easier.;[1]工程学是一门将科学知识适用于实践的专业．工程师运用科学原理设计建筑物、机器以及各种各样的产品．他们寻找更好的方法来使用理存的资源，同时也经常开发新材料．在大部分使我们生活得更加容易的现代科技的创新方面，比如：工具、材料、技术以及能源等，工程师都发挥了直接作用．;[2] The field of engineering includes a wide variety of activities. For example, engineering projects range from the construction of huge dams to the design of tiny electronic circuits. Engineers may help produce guided missiles, industrial robots, or artificial limbs for the physically handicapped. They develop complex scientific equipment to explore the reaches of outer space and the depths of the oceans. ;[2]工程学领域包括有各种不同的活动，比如，工程项目涵盖内容可大到水坝的建设，小到细微的电子线路的设计。工程师可以帮助生产导弹、工业用机器人或为身体有残疾的人生产假肢。他们开发复杂的科学设备来勘探外层空间的范围和海洋的深度。;[2] Engineers also plan our electric power and water supply systems, and do research to improve automobiles, television sets, and other consumer products. They may work to reduce environmental pollution, increase the worlds food supply, and make transportation faster and safer. ;[2] 工程师还为我们规划电力和供水系统，研究改善汽车，电视机以及其他消费晶。他们致力于减少环境污染，增加世界粮食的供应，以及使运输更加快捷和安全。;[3] The history of engineering is the record of human ingenuity through the ages. Even in prehistoric times, people adapted to basic engineering techniques from things that were available in nature. For example, sturdy sticks became levers to lift large rocks, and logs were used as rollers to move heavy loads. The development of agriculture and the growth of civilization brought about a new wave of engineering efforts. ;[3]工程学的历史即是人类世世代代独具匠心的记录．甚至是在史前时期，人们就利用自然里可获得的事物作为原始的工程手段．例如，结实的棍子用作撬起巨大岩石的杠杆，原木用作移动重物的滚筒。农业的发展和文明的进步带来了工程学研究的新浪潮
