I. Read the following passage and then finish the task International Trade Every time we walk into a store, restaurant, theater or any other place of business to buy something, we trade. Basically, international trade does not differ from trade with other people in our country. The key to understanding trade is to remember why it takes place. The reason people trade, regardless of where they live, is that they believe they will be better off by trading. When we consider the alternative—each of us producing everything for ourselves—trade simply makes more sense. The process of importing and exporting creates a greater variety of goods and services because it permits countries to specialize in what they do best. By specializing in the goods it can produce most efficiently, a country can increase production and have the opportunity to make more sales and profits. Profits can turn into increased wages for the work force and additional investment in plants and equipment. The process also provides consumers with more goods at lower prices. The process of importing and exporting creates a greater variety of goods and services because it permits countries to specialize in what they do best. By specializing in the goods it can produce most efficiently, a country can increase production and have the opportunity to make more sales and profits. Profits can turn into increased wages for the work force and additional investment in plants and equipment. The process also provides consumers with more goods at lower prices. The benefits of trade can be explained using the economic principles of absolute and comparative advantage. For example, suppose there are a lawyer and a legal assistant. If it takes the lawyer less time to prepare briefs or to type letters than it does the assistant, in economic language, the lawyer has an “absolute advantage” both in preparing legal briefs and in typing letters. If we stopped here, we might be inclined to say that the lawyer should produce both, because the lawyer is better at both. According to comparative advantage, the lawyer should specialize in his or her strongest skill—the law, and the legal assistant—typing letters. If they do, they actually will produce more than if each of them had tried to do both tasks alone. Specializing in what they do best and then trading their products for the other things they need will make both parties better off. Through international trade, countries exchange goods they produce most efficiently for goods other countries produce most efficiently. The more consumers there are in the market, the greater the ability of each country to specialize in what it does best. It is important to note that both the lawyer and the legal assistant would benefit from specialization and trade. Likewise, international trade is a win-win situation for all countries that participate. Task 1 Decide whether the statements are true (T) or False(F) according to the passage.Please fill F or T in the bracket. (____) 1. Trading often takes place in our daily life. (____) 2. A country has the opportunity to make moreprofits if it decreases wages for the work force and                   investment in plants and equipment. (____) 3. If a ctry specializes in what it produces best, itwould make feweounr profits because it loses the opportunity to sell other goods. (____) 4. According to comparative advantage, peopleshould specialize in what they do best and then trade their products for the things they need. (____)5. A win-win situation means that both the country and its consumers can benefit from                                    international trade.
