12.由图6中人民币价格由E到E'的走势可以判断出①人民币对英镑汇率下降,英镑在贬值②英镑对人民币汇率下降,人民币升值③中国出口到英国的商品竞争力会增强④英国留学生在中国留学的费用会增加A.①③B.①④C.②③D.②④【答案】D【考点定位】汇率变动的影响【知识拓展】汇率(又称外汇利率,外汇汇率或外汇行市)两种货币之间的对换的比率,亦可视为一个国家的货币对另一种货币的价值。
汇率又是各个国家为了达到其政治目的的金融手段。
汇率会因为利率,通货膨胀,国家的政治和每个国家的经济等原因而变动。
而汇率是由外汇市场决定。
外汇市场开放予不同类型的买家和卖家以作广泛及连续的货币交易(外汇交易除周末外每天24小时进行,即从GMT时间周日8:15至GMT时间周五22:00。
即期汇率是指于当前的汇率,而远期汇率则指于当日报价及交易,但于未来特定日期支付的汇率)。
一国外汇行市的升降,对进出口贸易和经济结构、生产布局等会产生影响。
汇率是国际贸易中最重要的调节杠杆,汇率下降,能起到促进进出口、抑制进口的作用。
例如,一件价值100元人民币的商品,如果人民币对美元的汇率为0.1502(间接标价法),则这件商品在美国的价格就是15.02 美元。
如果人民币对美元汇率降到0.1429,也就是说美元升值,人民币贬值,用更少的美元可买此商品,这件商品在美国的价格就是14.29美元。
所以该商品在美国市场上的价格会变低。
商品的价格降低,竞争力变高,便宜好卖。
反之,如果人民币对美元汇率升到0.1667,也就是说美元贬值,人民币升值,则这件商品在美国市场上的价格就是16.67美元,此商品的美元价格变贵,买的就少了。
13.国企改革将是“十三五”规划的重中之重,国务院印发的《关于国有企业发展混合所有制经济的意见》指出,发展混合所有制经济,是深化国有企业改革的重要举措。
国有企业的混合所有制改革旨在①巩固国有经济在国民经济中的主体地位②实现不同所有制经济在社会主义经济中的平等地位③放大国有资本功能,实现国有资产保值增值,提高竞争力④有利于实现国有企业投资主体多元化和公有制实现形式多样化A.①②B.③④C.②③D.①④【答案】B【考点定位】我国的基本经济制度【易错易混】正确区分我国基本经济制度的几组易混概念(1)公有制的主体地位与国有经济的主导作用。

AOne of the odd things about some business organizations is that they spend so much money attracting new customers but spend so little keeping them. It just doesn’t make sense. However, taking customers for granted is a routine in some business organizations.Loyal customers are an organization's only protection against bankruptcy(破产), and losing them because of neglect or indifference is really wrong. Not only do satisfied customers continue to buy by themselves, but they often encourage others to buy. This is advertising that doesn't cost a penny. Although there are always problems in giving good service to customers, maintaining their business isn't all that difficult. It's a matter of attitude, of believing that everyone who buys from you is entitled to the best treatment you can deliver. Plus giving just a little more than you have to.There are always problems in giving good service to customers. The reason, of course, is that no organization is perfect, and there's many a slip: unreasonable delays in filling orders, shipping the wrong goods, failing to answer letters promptly, and so on. Sometimes these errors or failures can't be helped. For example, if you can't get parts because of material shortages or a transportation strike, customers may be denied the goods they've ordered.No matter who is at fault, customers whom you value highly should generally benaturally, get more attention than those who buy infrequently and have to be badgered to pay what they owe. However, you have to make the assumption that all customers are good unless proved otherwise.1. From the second paragraph, we can know that ____________.A. satisfied customers should always be well servicedB. devoted customers are lifelines of business organizationsC. companies can employ customers to advertise their productsD. it is hard for organizations to offer good services to their customers2. Which of the following statements might the author agree with?A. Only regular customers deserve good treatmentsB. New customers are treated well in large organizationsC. Some errors and failures in business are unavoidableD. Both an organization and their customers are responsible for certain errors3. What does the author imply by saying “all customers should be treated alike isa myth”?A. I t’s not true that all customers are treated equallyB. It is an old story that customers receive equal treatmentC. It is possible that customers should enjoy the same treatmentD. It’s a rule that customers should share equal and fair rights4. The main idea of the passage is best summarized as “_________”.A. new customers are kings for business organizationsB. taking customers for granted is regulation in business organizationsC. maintaining customers is the most important thing to business organizationsD. business organizations need spend so much money attracting new customersBThink about the longest elevator ride that you’ve ever taken. Whether you rose five or 100 floors, it probably took less than a few minutes. Now imagine riding in an elevator higher and higher as it climbs for nearly a day. When you reach the top floor, prepare for views that are really out of this world. You’ll be in space!Space elevators might sound like a crazy idea, but they’re something scientists have been working on for decades.At the moment, riding in a capsule is the only way ordinary people can get to and from space. But those rides are very expensive---about $ 25 million per person per flight. Now scientists are making efforts to reduce the expense of those rides.Researchers are still figuring out the details about how a space elevator might work. One idea is stretching a very long cable —more than 37,000 kilometers —up to space from the earth’s equator (赤道). Objects in space above the equator orbit (绕……的轨道飞行) the earth at the same speed that our planet turns. A weight on the end of the cable would stretch it tight. An elevator tied to the cable could use it to climb up and down.The only problem is that besides being long, this cable must also be very strong. Storms, including hurricanes might break it. One way to solve this problem is to stretch the cable from the moon instead of from the earth. Airplanes designed to climb higher than a typical jet might take off from the earth and link up with the cable, which would be held in place by the pull of gravity from the earth. An elevator car waiting there would then take riders the rest of the way to the moon. Fueled by solar power, the elevator could transport people and materials without much expense or effort per ride.5. The first paragraph is presented by _____.A. asking questionsB. analyzing causesC. giving an exampleD. making a comparison6. Why have scientists been working on space elevators?A. To make trips to space cheaper.B. To help astronauts do research in space.C. To find a more convenient way to the moon.D. To prove an assumption which seems crazy.7. The underlined word “it”in Paragraph 3 refers to _____.A. the weightB. the cableC. an object in spaceD. the equator8. What may make the cable stay in place on the moon?A. The elevator car on the moon.B. The elevator fastened to the cable.C. The pull of gravity from the earth.D. The speed of the moon orbiting the earth.CChildLife Liquid Calcium with Magnesium(镁) provides these two essential minerals combined with Vitamin D and Zinc in a balanced, absorbable, great tasting formula.

The World Economic Forum founder Klaus Schwab reminded Africa that 18 million jobs will have to be created every yearWhat is also required is great investment in both education and employment, so that the young can start building businesses and developing the technologies to provide opportunities for the coming boom generation. They deserve the chance to live without the chaos and conflict that once haunt the continent for years.12. What is the main idea of the first two paragraphs?A.

Born in West Virginia, Nash displayed a keenness for mathematics early in life,independently proving Femret's little theorem(定理)before graduating from high school. By the time he turned 30 in 1958,he was an unquestionable academic celebrity. At Princeton, Nash published a 27-page thesis that led to applications to economics,international politics, and evolutionary biology His signature solution-known as a "Nash Equilibrium(纳什均衡)”-found that competition among two opponents,not necessarily governed by zero-sum logic. Two opponents can, for instance,each achieve their maximum objectives through cooperating with the other, or gain nothing at all by refusing to cooperate. It is now regarded as one of the most important social science ideas in the 20th century. In the late 1950s, Nash began a slide into mental illness. By the time Nash was awarded the Nobel Prize in Economics in 1994, he hadn't published a paper in 36 years. But like a child cured of a nightmare by the switch of a light, Nash recovered from his illness seemingly by choosing not to be sick anymore. He continued to work, travel,and speak at conferences for the rest of his life. In 2001,the release of the film A Beautiful Mind,based an Sylvia Nasar’s 1998 book of the same name,introduced Nash's unusual life story to an international audience 21. John Nash passed away because of__________ A. a mental illness B. overwork C. a traffic accident D. starvation 22. According to“Nash Equilibrium",what will happen if two opponents refuse to cooperate? A. They will get nothing at all. B.They will get what they really want C. 'They will lose the support from each other D. They will achieve their maximum objectives. 23. Which of the following can be the best title for the text? A. John Nash's Sudden Death B. John Nash's Extraordinary life C. John Nash's Equilibrium D. John Nash's Mental illness. 【答案】 21.C 22.A 23.B
