Luckily. the orange grower and the shirt manufacturer are willing to accept U.S. dollars for their expenses. Trade can be carried on in dollars. Economic transactions within a country are relatively simple. If I want to buy a British bicycle, however, matters become more complicated. I must ultimately pay in British money, or British pounds,” rather than in dollars. Similarly, if the British want to buy U.S. merchandise, they must obtain U. S. dollars. And the requirement to obtain foreign currencies bolds for other countries as well.We see, then, that international trade introduces a new element: the foreign exchange rate, which denotes the price of a foreign countrys currency in terms of our own.Here are some examples: The U. S. dollar price of a British pound was recently $ I. 80; for a British resident wanting to buy U. S. goods, the price of a dollar was 1/$1.80= 0.56. There is also a foreign exchange rate between U. S. dollars and the currency of each and every country, In mid1988, the foreign exchange rate was 60 cents for a German mark, 18 cents for a French franc, 80 cents for a Canadian dollar, and 0. 8 cent for a Japanese yen. For foreigners desiring to buy dollars, the reciprocal prices were 1. 67 German marks. 5. 56 French francs, 1.25 Canadian dollars, or 125 Japanese yen for each U.S. dollar.Given the foreign exchange rate, it is now possible for me to buy my English bicycle. Suppose its quoted price is , 100（i.e. , 100 British pounds）. All I have to do is look in the newspaper for the foreign exchange rate for pounds. If this is $1.80 per pound, I simply go to a bank with $180 and ask that the money be used to pay the English bicycle exporter. Pay with what? The bank pays with pounds, of course, the kind of money the exporter needs.You should be able to show what British importers of American grain have to do if they want to buy, say a $ 36,000 shipment from an American exporter. Here pounds must be converted into dollars. You will see that, when the foreign exchange rate is $1.80 per pound, the grain shipment costs them 20,000.Businesses and tourists do not have to know anything more than this for their import or export transactions. But the true economics of foreign exchange rates cannot be grasped until we find out why the foreign exchange rate is at a given level.1. It can be inferred that the writer is .A. British. B. American. C. Chinese. D. French.2. What is meant by the third paragraph?A. The foreign exchange rate is an element coming with international trade dealing with foreign countries currency.B. International trade introduces the clement of the foreign exchange rate indicating a foreign currency at our own priceC. The foreign exchange rate is a new element in international trade indicating the price of a countrys currency in terms of the price of another countrys currency. D. The foreign exchange rate is an element introduced to denote the price of a foreign currency in terms of the price of another foreign currency.3. In mid1988, how much dollars did one have to have in order to exchange for 10,000,000 Japanese yen?A. 8,000,000 B. 80,000 C. 800,000 D. 80,000,0004. What do British importers have to do if they want to buy $ 36,000 worth of grain from an American exporter?A. They have to pay British pounds directly.B. They have to pay French francs.C. They have to convert 36,000 U.S. dollars into 20,000 British pounds.D. They have to convert 20,000 British pounds into 36,000 U.S. dollars.5. The last paragraph implies that businesses and touristsA. do not have to know the true economies of foreign exchange rates.B. do not have to know more the true economics of foreign exchange rates.C. have to know nothing more than economics of foreign exchange rates.D. do not have to grasp the true economics of foreign exchange rates at a given level.【试题答案】一. 单项选择：1.
