Hi, teachers and friends. I have some questions about the paragraph: “Government bureaucracies and large corporations account for most of the global expenditures on research and development, and they have the resources to take innovations from the laboratory bench through the testing stage and into widespread use. They are thus the prime actors in the development and application of new technologies. Public influence over this process is exercised chiefly through purchasing power in the marketplace-which is itself shaped by the advertising budgets of the industries that develop new technologies—and through political pressures in the halls of government. Usually however, public influence is limited to attempts to curb the use of technologies that are already well along the path to development, such as nuclear power or supersonic transportation; there is little opportunity for individuals to have much impact on the processes that lead to the generation of new technologies. My questions are: 1. Are there any differences between market and marketplace? 2. In “…which is itself shaped...", is the word “itself” correctly positioned? 3. Why the line in “marketplace-which” is shorter than that in “technologies—and”? 4. Is “the halls of government” a meeting room in the government’s office building where officials discuss big issues, or sth else? Is it a proper noun? I used to watch a movie entitled The City Hall (I guess so, if I don’t remember wrongly), which talks about the affairs of the New York’s political circle and stars Al Pacino (the godfather), the hall is kind of a figurative term…. 5. In “already well along the path”, I know both “already” and “well” are intended to emphasize “along the path”, but do they work well together here? Ha.. 6. Is “nuclear power” here related to any military purpose? Ha, many small questions, it’s gonna take my teachers’ time, but, I’m your student, ha. Thank you in advance.
