Introduction （文化背景知识介绍） Science is knowledge of facts, laws and relationships that is obtained through systematic observation and experimentation. When we think of science we normally think of exact sciences like biology, chemistry and physics. But many other branches of sciences have developed over the past century. Sociology and psychology, for example, are not exact sciences although their findings are based on the principles of scientific investigation. Since most people in society do not work as scientists, they tend to perceive science as it affects them in their daily lives. In other words, they see the practical and the applied aspects of science. Scientific knowledge applied to practical uses is normally referred to as technology. Robotics, for instance, is a branch of technology involving the study and production of manlike machines capable of performing human tasks. For many years, robots belonged to the realm of science fiction but now they are used in various manufacturing sector including the auto industry. Robots have become increasingly complex and sophisticated. So people predict that, in the not too distant future, robots will be capable of feeling the same emotions as humans. It is hard to imagine an emotionally independent machine, but many of the things we take for granted now were once considered to be ridiculous dreams. The technological changes that took place in the 20th century revolutionized virtually every aspect of life from communication to material comfort. In the space of two or three generations, people witnessed major advances in medical research, nuclear energy and space exploration. In some cases, they have made life more convenient and more enjoyable. In other cases, however, they have resulted in a serious erosion of our privacy. Information and activities that we consider private are now readily available to public and private agencies. Whether we like it or not, we are being watched and monitored on a regular basis.

Whether we like it now not, e are being watched or monitored on a regular basis. Despite the negative reactions which many technological inventions have generated in recent years, some people still regard science in a positive light and look forward to waking up in the distant future. Such is the case for people who believe that liquid nitrogen holds the key to the long-term preservation of the body. These people often believe that death is merely an illness, which science will eventually be able to cure. Their hopes seem strange today. But who knows what the future will bring?
