听力原文：M: Hi, would you like some help？
W: Well, I'm looking for something I saw at a friend's house a few days ago. He said he bought here in your store. It's a bright metal shelf, almost a yard long and two feet high. It can be attached to a cabinet or refrigerator. I'm a biologist and I want to use it for my slides and samples.
M: You're in the right department. But I'm sorry to tell you that we don't have it in stock now. It seems that quite a few people are in need of it.
W: Oh, that's too bad. Are you going to get more？ When is it possible for me to come again to buy it？
M: They are on order now. They will arrive in about several days. I will inform. you as soon as it is available. But what I should tell you is that the price has gone up a little.
W: Just my luck. Anyhow I don't mind the price because it is what I'm looking for.
M: Right! When you really need something and find it useful, price is second in consideration.
W: Would you tell me something about the price change？
M: Originally they were $12.50. But the new ones will almost three dollars more. Stop in next week. We should have them by then.
Where is the conversation most likely taking place？

Economists are only now realizing the full extent to which the communications revolution has affected the world economy. Information technology allows the extension of trade across geographical and industrial boundaries, and transnational corporations take full advantage of it. Terms of trade, exchange and interest rates and money movements are more important than the production of goods. The electronic economy made possible by information technology allows the haves to increase their control on global markets--with destructive impact on the have-nots.
For them the result is instability. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine. As "futures" are traded on computer screens, developing countries simply have less and less control of their destinies.
So what are the options for regaining control？ One alternative is for developing countries to buy the latest computers and telecommunications themselves—so-called "development communications" modernization. Yet this leads to long-term dependency and perhaps permanent constraints on developing countries' economies.
Communications technology is generally exported from the U. S., Europe or Japan; the patents, skills and ability to manufacture remain in the hands of a few industrialized countries. It is also expensive, and imported products and services must therefore be bought on credit--credit usually provided by the very countries whose companies stand to gain.
Furthermore. when new technology is introduced there is often too low a level of expertise to exploit it for native development. This means that while local elites, foreign communities and subsidiaries of transnational corporations may benefit, those whose lives depend on access to the information denied it.
From the passage we know that the development of high technology is mostly in the interests of ______.
