[单项选择]Passage Four

Science is an enterprise concerned with gaining information about causality, or the relationship between cause and effect. A simple example of a cause is the movement of a paddle as it strikes a ping-pong ball; the effect is the movement of the ball through the air. In psychology and other sciences, the word "cause" is often replaced by the term "independent variable". This term implies that the experimenter is often "free" to vary the independent variable as he or she desires (for example, the experimenter can control the speed of the paddle as it strikes the ball). The term "dependent variable" replaces the word "effect", and this term is used because the effect depends on some characteristic of the independent variable (the flight of the ball depends on the speed of the paddle). The conventions of science demand that both the in A. predict variations in a person’s performance B. indicate a hard nut to crack in physics C. prove a common feature most theories have D. show the negligibility of intervening variables 查看答案 更多"Passage Four Science is a"的相关试题: [单项选择]Passage Four Science is an enterprise concerned with gaining information about causality, or the relationship between cause and effect.

The conventions of science demand that both the in A. cause and effect can be independent of each other B. there is hardly anything that happens without a cause C. dependent and independent variables affect each other D. cause and effect may vary respectively in most events 查看答案 [单项选择]Passage Four In science the meaning of the word "explain" suffers with civilization’s every step in search of reality. Science can not really explain electricity, magnetism, and gravitation; their effects can be measured and predicted, but of their nature no more is known to the modem scientist than to Thales who first speculated on the electrification of amber. Most contemporary physicists reject the notion that man can ever discover what these mysterious forces "really" are. Electricity, Bertrand Russell says, "is not a thing, like St. Paul’s Cathedral; it is a way in which things behave." When we have told how things behave when they are electrified, we have told all there is to tell. Until recently scientists would have disapproved of such an idea. Aristotle, for example, whose natural science dominated Western thought for two thousand A. to explain why things happen B. to explain how things happen C. to describe self-evident principles D. to support Aristotelian science 查看答案 [单项选择] Passage Four The remarkable progress of science and technology in the 20th century has brought enormous benefits to humankind. Long and healthy lives, economic prosperity and a pleasant and convenient living environment have resulted from technological progress based on advances in scientific knowledge. This progress will continue or may even accelerate in the future, because both the number of scientists and their activities are expanding throughout the world. We may expect, therefore, that science and technology will continue to contribute to the development of human society. At the same time, rapid scientific advances may raise some difficult problems. First of all, the disparity in scientific knowledge between those in scientific and technical professions and those in other areas will continuously expand. This may create a communications gap between the two groups that could affect obtaining public consent on important issues, such as the use of genetic A. may cause the lack of scientists throughout the world in the century to come B. is mainly due to the explosion of scientific information C. may increase the communications gap between young people and scientists D. may hinder the development of human society 查看答案 [单项选择]Passage Four 　　　　　　　　　　　　　　　　　　　　　　　　　　Software Systems Specialist Work Schedule: Full Time Salary: $ 62,500- $ 92,000* Location: Washington, DC metropolitan area * Employees within the organization have opportunities for additional salary advancement to the Expert level.
