单选题
What is the discussion mainly about?
【正确答案】
B
【答案解析】[解析] 12-17
W1: In our last meeting we discussed how science is a process. Science involves formation of a hypothesis and the testing of that hypothesis through observation and experimentation. We use this process to answer our questions about nature. Today we"ll focus on science and technology. Technology, especially in the form of new instruments, can extend our ability to observe and measure natural phenomena. Technology enables us to work on questions that were previously unapproachable. In turn, technology often applies the discoveries of science. Can anyone think of an example of technology that applies scientific knowledge? Yes, Rosa?
W2: The electron microscope. The people who invented the electron microscope used electromagnetic theory from physics.
W1: Yes. The electron microscope is an excellent example of applied science. What else is there?
M1: Well, there are all sorts of computer models, and there"s DNA technology, which is used in forensic science, and there"s genetic engineering used in agriculture. Computer models and genetic engineering are applied science.
W1: Yes, those are all good examples of technology that applies scientific knowledge. A lot of technology was developed as a direct result of the scientific process. On the other hand, not all technology can be described as applied science. In fact, technology came before science in human prehistory. In prehistoric times, technology was driven by inventive humans who built tools, made pottery, designed musical instruments, and so on, all without science-- that is, without people necessarily understanding why their inventions worked.
M2: Technology might not be scientific, but I think technology mostly helps us. It helps us cure diseases so people can live longer. It lets us produce more food than ever before. We can go places and build in places where we never could before.
W1: But look at the environmental consequences, like acid rain and pollution.
M1: Not to mention nuclear accidents, toxic waste, global warming, and extinction of species--technology can"t save us from ourselves.
W1 : You"re all raising some very important issues. Technology has improved our standard of living in many ways. It"s kept us healthier and enabled us to live longer lives. It"s enabled the human population to grow by a factor of ten in just a few centuries. But technology is a double-edged sword. You"ve just mentioned some of the environmental repercussions. Technology does have to be watched closely, monitored, and even criticized. Science and technology are partners. Science can help us identify problems and provide insight about what course of action may prevent further damage. But solutions to these problems have as much to do with politics, economics, and culture as they do with science and technology.
M1: I think scientists have a responsibility to educate politicians and the public about the consequences of certain technologies--such as genetic engineering. This is why I"m a science major now, but I"ve decided to get a master"s degree in public policy.
W1: And a decision like that is important. Scientists should try to influence how technology applies the discoveries of science. The relationship between science and technology is very important. It"s a relationship that is crucial to our study of life.
The speakers mainly discuss how science and technology are connected. The professor says:Today we "ll focus on science and technology; ... technology often applies the discoveries of science; Science and technology are partners; The relationship between science and technology is very important.
