答案 The main topic of the passage is "research and development". The lecturer wants to tell us how the interrelationship of science, technology and industry has developed and the multidirectional tendency of the development.
    By the middle of the nineteenth century, the public had been aware that the advance of science would lead to economic benefits. And then people had the common pattern assumption of science-industry. The progress was a linear one which started from basic science to technology and then to industrial use.
    In a modern society, basic research is conducted in practical ways. And new developed sciences can help us to solve specific technical or economic problems.
