根据以下材料回答下面的题目:Benefited or HurtFor the most part, it seems, workers in rich countries have little to fear from globalization, and a lot to gain. But is the same thing true for workers in poor countries? The answer is that they are even more likely than their rich country counterparts to benefit, because they have less to lose and more to gain. Orthodox economics takes an optimistic line on integration and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labor have already been used up. If pool countries lower their barriers to trade and investment, the theory goes: rich foreigners wilt want to send over some of their capital.If this inflow of resources arrives in the form of loans or portfolio investment, it will supplement domestic savings and loosen the financial constraint on additional investment by local companies. If it arrives in the form of new foreign controlled operations, FDI, so much the better: this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investmentought to push incomes up, partly by raising the demand for labor and partly by making labor more productive. This why workers in FDI receiving countries should be in an even better position to profit from integration than workers in FDI sending countries. Also, with or without inflows of foreign capital, the same static and dynamic gains from trade should apply in developing countries as in rich ones. This gain from trade logic often arouses suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets though trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory, trade is a positive sum game. In all these transactions, sides exporters and importers, borrowers and lenders, shareholders and workers can gain.According to the passage, who may be reasonably afraid of the globalization?
回答下面的题目: The Supercomputer Network1. Recently ten laboratories run by governments in different parts of the world have become linked. Their computers have been connected so they can "talk" to each other. This may not seem very dramatic news, but it is the beginning of a development that will increase the power of the Internet tremendously.2. The Internet is an interconnected ( 互联 ) system of networks that connects computers round the world and facilitates the transmission and exchange of information. The way that you use the lnternet is by accessing this network. This depends on the power that your system allows you to use. The power of your computer is responsible for how fast you can download ( 下载 ) files, how much data you can store, etc. If your computer is old and slow, accessing the information can be very difficult.3. The new development in information technology has been called "the grid" (网络技术), and it will be a network of computers that are linked together. The "grid" will work in a different way from the Internet, enabling you to get the power of the biggest computers in the world on your computer. Accessing the information will no longer depend on the power of your computer. The idea is that while you accessinformation, you will also have access to the power of the bigger computer stations.4. One advantage of this revolutionary idea is that geographical location will become irrelevant. The "grid" will decide which are the best parts of a worldwide network to do the job you want. This means that you may be accessing a computer in Japan to solve a problem in Alaska.5. The "grid" can be compared to having an efficient personal assistant. You can give your assistant a task and "he" will do it for you. The assistant will do the preliminary research, collect the data, compare them and decide on the best course of action by accessing any of the computer centres in the "grid" that happen to have the relevant information. All you have to do is assign the task, sit back and wait.6. At present, possible applications of the "grid" in scientific research are being explored. While it has taken about fifteen years for Internet use to become widespread, experts believe that the "grid" could be up and running for private individuals far more quickly. Scientists working on "grid" projects are convinced that it will be as widely used as the web in the next ten years.Paragraph 2__________
