13、 sources of clean energy needs to be 2 line with their interests. Clean energy has been given greater prominence than ever before; it is seen as a new industrial 3 and 4 of economic growth for the new century. The time for clean energy has come. In China, clean energy is moving ahead at full speed.

14、Take wind power as an example: by the end of last year, China had 5 wind power generating capacity of 12.21 GW, making China the largest wind power generator in Asia and first in the world. But according to the research, one-third of wind power capacity is running 6 due to an inability to get the po

Spain and Ireland are in trouble even if the percentage of their publ

21、ic debt in gross domestic product is much smaller than that of Germany. Italy, also in the financial markets“ crosshairs, has high public debt but a lower deficit than the eurozone“s average. The root of these countries“ problems is that their prices and wages have risen much faster than those of ot

22、her eurozone members. There are two ways to mitigate the pain. First, to adopt temporarily more expansionary fiscal policies for a while. Or, more powerfully, the wider euro area could adopt more expansionary monetary policies for several years. As to the second option, the “inflation fundamentalist

23、s“ will have none of it. This elite consisting of central bankers, top economic officials, politicians, academics and journalists insists that it is unacceptable to allow inflation to climb above two percent. Hyper-inflation in Germany in the 1930s and stagflation in industrial countries in the 1970

24、s and 1980s support their view. It“s true that moderate inflation can creep up to become high inflation. But inflation fundamentalism can also hurt. There is little if any empirical evidence that moderate inflation hurts growth. In most countries, cutting actual wages is politically difficult if not

25、 impossible. But, to regain competitiveness and balance the books, real wage adjustments are sometimes in- evitable. A slightly higher level of inflation allows for this painful adjustment with a lower level of political conflict. On the other hand, ultra-low inflation, in a recession, can easily be

26、come deflation. Falling prices encourage people to defer spending, which makes things worse and erodes tax payments, impairing a government“ s ability to pay debt. That in turn increases the debt“s size and costs. In addition, a single-minded focus on inflation makes it easy for policymakers to lose

27、 sight of the broader picture-asset prices, growth and employment. Policy can become too tight or too loose-as in the run-up to the crisis in the U.S. when low inflation was seen as a comforting sign that things were in order. In a recession, ultra-low inflation also reduces the effectiveness of mon

28、etary policy since interest rates cannot go below zero. The crisis in the euro area highlights the need for a more openminded discussion of the merits and costs of ultra-low inflation.（分数：5.00）(1).In the author“s opinion, the second way to mitigate the pain is _.（分数：1.00）A.cutting the spendingB.cont

29、rolling inflation within two percentC.ultra-low inflationD.moderate inflation(2).Which of the following inflation might be accepted by the author?（分数：1.00）A.2%.B.1%.C.4%.D.8%.(3).We can learn from the fourth paragraph that _.（分数：1.00）A.moderate inflation hurts growthB.it is unnecessary to cut actual

30、 wagesC.the author opposes moderate inflationD.the author opposes inflation fundamentalism(4).The word “books“ ( line 5, paragraph 4) means _.（分数：1.00）A.ticketsB.accountsC.worksD.stamps(5).What is the text mainly about?（分数：1.00）A.The core of Greece“s trouble.B.Two ways to solve the problems of Greec

31、e, Spain, Ireland and Italy.C.The merits of inflation fundamentalism.D.The shortcomings of inflation fundamentalism.九、Text 2(总题数：1，分数：25.00)Slavery has played a significant role in the history of the U.S. It existed in all the English mainland colonies and most of the Founding Fathers also had slave

32、s, as did eight of the first 12 presidents. Dutch traders brought 20 Africans to Jamestown, Virginia, as early as 1619, however, throughout the 17th century the number of Africans in the English mainland colonies grew very slowly. At that time, colonists used two other sources of unfree labor: Nativ

33、e American slaves and European indentured servants. During those years, every colony had some Native American slaves, but their number was limited. Indian men avoided performing agricultural labor, because they viewed it as women“s work, and colonists complained that they were too “haughty“. The mor

34、e important was that the settlers found it more convenient to sell Native Americans captured in war to planters in the Caribbean than to turn them into slaves, because they often resisted and it was not hard for the slaves to escape. Later, the policy of killing Indians or driving them away from whi

35、te settlements was proposed and it contradicted with their widespread employment as slaves. The other form of labor was the white indentured servitude. Most indentured servants consisted of poor Europeans. Desiring to escape tough conditions in Europe and take advantage of fabled opportunities in Am

36、erica, they traded three to seven years of their labor in exchange for the transatlantic passage. At first, it was mainly English who were the white indentured servitude but later increasingly Irish, Welsh, and German joined. They were essentially temporary slaves and most of them served as agricult

37、ural workers although some, especially in the North, were taught skilled trades. During the 17th century, they performed most of heavy labor in the Southern colonies and also consisted of the bulk of immigrants to those colonies. At the end of the 17th century, in order to meet the labor need, lando

38、wners in America turned to African slaves. During the late 17th and 18th centuries, thanks to the dominant position of England in terms of naval superiority, English traders ( some of whom lived in English America) transported millions of Africans across the Atlantic. And the transatlantic slave tra

39、de produced one of the largest forced migrations in history, blacks ( the great majority of whom were slaves) increasing from about 7 percent of the American population in 1680 to more than 40 percent by the middle of the 18th century.（分数：25.00）(1).Which of the following was true of the slavery in A

40、merica?（分数：5.00）A.The colonists sold African Americans to planters in the Caribbean.B.Native American slaves performed agricultural labor.C.During the 17th century, the white indentured servitude was the main labor in the Southern colonies.D.It was at the end of the 17th century that African people

41、began to be brought to America.(2).We can infer from the sentence “Later, the policy of killing Indians or.contradicted with their widespread employment as slaves“ that _.（分数：5.00）A.many Indians were killed by White settlersB.many Indians were drove away from white settlementsC.the Indians were slav

42、es in a wide-spread wayD.white settlers had to find other sources of labor(3).In the third paragraph, the author mainly argues that _.（分数：5.00）A.the number of Native American slaves was very smallB.the colonists thought that the Native American slaves were very haughtyC.the Native American slaves ha

43、d been treated cruellyD.the Native American slaves always resisted(4).Which of the following wasn“t the opinion of the colonists towards the Native American slaves?（分数：5.00）A.The Native American slaves were very haughty.B.The Native American slaves were very lazy.C.The Native American slaves were ha

44、rd to control.D.The Native American slaves always found ways to escape.(5).The relation between the second paragraph and the next following two paragraphs is that in the next following two paragraphs the author _.（分数：5.00）A.further elaborates the issue discussed in the second paragraphB.modifies the

45、 point of view in the second paragraphC.changes the view expressed in the second paragraphD.offers the reason to support the viewpoint in the second paragraph十、Text 3(总题数：1，分数：25.00)U.S. health officials are increasing surveillance measures at doctors“ offices and international borders to guard agai

46、nst the spread of swine flu. Washington also has begun dispersing medicine from a federal stockpile. The Centers for Disease Control and Prevention says there have been only mild cases of swine flu in the United States, but experts remain on guard. Acting agency director, Richard Besser, says the ep

47、idemic in Mexico prompted U.S. doctors to begin monitoring actively for possible infections. “We are asking doctors when they see someone who has flu-like illness who has traveled to an affected region, to do a culture, take a swab in the nose and send it to the lab so we can see: is it influenza, i

48、s it this type?“ he said. Speaking Sunday at the White House, Besser said the extra detection efforts have enabled officials to find more infections than under normal circumstances. He also says he expects the number of infections will rise and the illness will spread to other U.S. regions, as docto

49、rs continue to monitor the problem. The Centers for Disease Control and Prevention says it does not recommend people travel to Mexico, where the outbreak of swine flu is centered and more than 100 deaths have been reported. But officials have not ordered a travel ban to the country. Homeland Security Secretary Janet Napolitano says, instead, airlines have the option of screening passengers on flights from Mexico. “We are letting air carriers and our employees at the gates on those flights make sure that they are
