3Yet for all the trouble procrastination may incur, delay can often inspire and revive a creative soul. Jean Kerr, author of many successful novels and plays, says that she reads every soup-can and jamjar label in her kitchen before settling down to her typewriter. Many a writer focuses on almost anything but his task—for example, on the Coast and Geodetic Survey of Maine'sFrenchmanBays imagination with names like Googins Ledge, Blunts Pond, Hio Hill and Burnt Porcupine, Long Porcupine, Sheep Porcupine and Bald Porcupine islands.

It is available following the application “Policy Coordination Failureand the Collapse of Fixed Exchange Rates: The Cases of Bretton Woods and the EMS” in thisinstructor’s manual and provides graphs showing the value of the yuan against the dollar andthe yenF) A new appendix, Appendix 13.A, provides a worked-out numerical exercise for the open-economy IS-LM model280 Abel/Bernanke/Croushore • Macroeconomics, Sixth EditionTeaching NotesI. Exchange Rates (Sec. 13.1)A. Nominal exchange rates1. The nominal exchange rate tells you how much foreign currency you can obtain with oneunit of the domestic currencya. For example, if the nominal exchange rate is 110 yen per dollar, one dollar can beexchanged for 110 yenb. Transactions between currencies take place in the foreign exchange marketc. Denote the nominal exchange rate (or simply, exchange rate) as e nom in units of the foreign currency per unit of domestic currency2. Under a flexible-exchange-rate system or floating-exchange-rate system, exchange rates aredetermined by supply and demand and may change every day; this is the current system formajor currencies3. In the past, many currencies operated under a fixed-exchange-rate system, in whichgovernments determined exchange ratesa. The exchange rates were fixed because the central banks in those countries offered tobuy or sell the currencies at the fixed exchange rateb. Examples include the gold standard, which operated in the late 1800s and early 1900s,and the Bretton Woods system, which was in place from 1944 until the early 1970sc. Even today, though major currencies are in a flexible-exchange-rate system, somesmaller countries fix their exchange ratesB) Real exchange rates1. The real exchange rate tells you how much of a foreign good you can get in exchange forone unit of a domestic good2. If the nominal exchange rate is 110 yen per dollar, and it costs 1100 yen to buy a hamburgerin Tokyo compared to 2 dollars in New York, the price of a U.S. hamburger relative to aJapanese hamburger is 0.2 Japanese hamburgers per U.S. hamburger3. The real exchange rate is the price of domestic goods relative to foreign goods, ore = e nom P/P For (13.1)4. To simplify matters, we’ll assume that each country produces a unique good5. In reality, countries produce many goods, so we must use price indexes to get P and P For6. If a country’s real exchange rate is rising, its goods are becoming more expensive relative tothe goods of the other countryC) Appreciation and depreciation1. In a flexible-exchange-rate system, when e nom falls, the domestic currency has undergone a nominal depreciation (or it has become weaker); when e nom rises, the domestic currency has become stronger and has undergone a nominal appreciation2. In a fixed-exchange-rate system, a weakening of the currency is called a devaluation, astrengthening is called a revaluation3. We also use the terms real appreciation and real depreciation to refer to changes in the realexchange rate Numerical Problem 1 is a simple example of appreciation and depreciation.Chapter 13 Exchange Rates, Business Cycles, and Macroeconomic Policy in the Open Economy 281D) Purchasing power parity1. To examine the relationship between the nominal exchange rate and the real exchange rate,think first about a simple case in which all countries produce the same goods, which arefreely tradeda. If there were no transportation costs, the real exchange rate would have to be e= 1, orelse everyone would buy goods where they were cheaperb. Setting e= 1 in Eq. (13.1) givesP=PFor /enom(13.2)c. This means that similar goods have the same price in terms of the same currency, aconcept known as purchasing power parity, or PPPd. Empirical evidence shows that purchasing power parity holds in the long run but not inthe short run because in reality, countries produce different goods, because some goods aren’t traded, and because there are transportation costs and legal barriers to trade2. When PPP doesn’t hold, using Eq. (13.1), we can decompose changes in the real exchangerate into parts∆e/e=∆enom /enom+∆P/P – ∆PFor/PFor3. This can be rearranged as∆enom /enom=∆e/e+πFor– π (13.3)4. Thus a nominal appreciation is due to a real appreciation or a lower rate of inflation thanin the foreign country5. In the special case in which the real exchange rate doesn’t change, so that ∆e/e= 0, theresulting equation in Eq. (13.3) is called relative purchasing power parity, since nominalexchange rate movements reflect only changes in inflationa. Relative purchasing power parity works well as a description of exchange-ratemovements in high-inflation countries, since in those countries, movements in relativeinflation rates are much larger than movements in real exchange rates6. Box 13.1: McParitya. As a test of the PPP hypothesis, the Economist magazine periodically reports on theprices of Big Mac hamburgers in different countriesb. The prices, when translated into dollar terms using the nominal exchange rate, rangefrom just over $1 in China to over $4 in Switzerland (using 2003 data), so PPP definitelydoesn’t holdc. The hamburger price data forecasts movements in exchange rates(1) Hamburger prices might be expected to converge, so countries in which Big Macsare expensive may have a depreciation, while countries in which Big Macs are cheapmay have an appreciationE) The real exchange rate and net exports1. The real exchange rate (also called the terms of trade) is important because it represents therate at which domestic goods and services can be traded for those produced abroada. An increase in the real exchange rate means people in a country can get more foreigngoods for a given amount of domestic goods2. The real exchange rate also affects a country’s net exports (exports minus imports)a. Changes in net exports have a direct impact on export and import industries in thecountryb. Changes in net exports affect overall economic activity and are a primary channelthrough which business cycles and macroeconomic policy changes are transmittedinternationally282 Abel/Bernanke/Croushore • Macroeconomics, Sixth Edition3. The real exchange rate affects net exports through its effect on the demand for goodsa. A high real exchange rate makes foreign goods cheap relative to domestic goods, sothere’s a high demand for foreign goods (in both countries)b. With demand for foreign goods high, net exports declinec. Thus the higher the real exchange rate, the lower a country’s net exportsData ApplicationHow sensitive are U.S. manufacturing firms to changes in the value of the dollar? LindaGoldberg and Keith Crockett provide an interesting overview of the data in their article “TheDollar and U.S. Manufacturing” in the Federal Reserve Bank of New York’s Current Issues inEconomics and Finance, November 1998.4. The J curvea. The effect of a change in the real exchange rate may be weak in the short run and caneven go the “wrong” wayb. Although a rise in the real exchange rate will reduce net exports in the long run, in theshort run it may be difficult to quickly change imports and exportsc. As a result, a country will import and export the same amount of goods for a time, withlower relative prices on the foreign goods, thus increasing net exportsd. Similarly, a real depreciation will lead to a decline in net exports in the short run and arise in the long rune. This pattern of net exports is known as the J curve (Figure 13.1)Figure 13.15. The analysis in this chapter assumes a time period long enough that the movements alongthe J curve are complete, so that a real depreciation raises net exports and a real appreciationreduces net exportsNumerical Problem 2 gives an example of how a real depreciation can cause net exports to fall.Chapter 13 Exchange Rates, Business Cycles, and Macroeconomic Policy in the Open Economy 283F) Application: The value of the dollar and U.S. net exports1. Our theory suggests that the value of the dollar and U.S. net exports should be inverselyrelated2. Looking at data since the early 1970s, when the world switched to floating exchange rates,confirms the theory, at least in the 1980s (text Figure 13.2)a. From 1980 to 1985 the dollar appreciated and net exports declined sharplyb. The dollar began depreciating in 1985, but it wasn’t until late 1987 that net exportsbegan to rise(1) Initially, economists relied on the J curve to explain the continued decline in netexports with the decline of the dollar(2) But two and one-half years is a long time for the J curve to be in effect(3) A possible explanation for this long lag in the J curve is a change in competitiveness(a) The strength of the dollar for such a long period in the first half of the 1980smeant U.S. firms lost many foreign customers(b) Foreign firms made many inroads into the United States(c) This is known as the “beachhead effect,” because it allowed foreign producersto establish beachheads in the U.S. economy(4) The U.S. real exchange rate and net exports moved in opposite directions from1997 to 2001(a) The strong dollar reduced net exports(b) But a bigger factor was weak growth in foreign economiesII. How Exchange Rates Are Determined: A Supply-and-Demand Analysis (Sec. 13.2)A) What causes changes in the exchange rate?1. To analyze this, we’ll use supply-and-demand analysis, assuming a fixed price level2. Holding prices fixed means that changes in the real exchange rate are matched by changesin the nominal exchange rate3. The nominal exchange rate is determined in the foreign exchange market by supply anddemand for the currency4. Demand and supply are plotted against the nominal exchange rate, just like demand andsupply for any good (Figure 13.2; like text Figure 13.3)Figure 13.2284 Abel/Bernanke/Croushore • Macroeconomics, Sixth Editiona. Supplying dollars means offering dollars in exchange for the foreign currencyb. The supply curve slopes upward, because if people can get more units of foreigncurrency for a dollar, they’ll supply more dollarsc. Demanding dollars means wanting to buy dollars in exchange for the foreign currencyd. The demand curve slopes downward, because if people need to give up a greater amountof foreign currency to obtain one dollar, they’ll demand fewer dollars5. Why do people demand or supply dollars?a. People need dollars for two reasons:(1) To be able to buy U.S. goods and services (U.S. exports)(2) To be able to buy U.S. real and financial assets (U.S. financial inflows)b. These transactions are the two main categories in the balance of payments accounts: thecurrent account and the capital and financial accountc. People want to sell dollars for two reasons:(1) To be able to buy foreign goods and services (U.S. imports)(2) To be able to buy foreign real and financial assets (U.S. financial outflows)6. Factors that increase demand for U.S. exports and assets will increase demand for dollars,shifting the demand curve to the right and increasing the nominal exchange ratea. For example, an increase in the quality of U.S. goods relative to foreign goods will leadto an appreciation of the dollar (Figure 13.3; like text Figure 13.4)Figure 13.3B) In touch with the macroeconomy: Exchange rates1. Trading in currencies occurs around-the-clock, since some market is open in some countryany time of day2. The spot rate is the rate at which one currency can be traded for another immediately3. The forward rate is the rate at which one currency can be traded for another at a fixed datein the future (for example, 30, 90, or 180 days from now)4. A pattern of rising forward rates suggests that people expect the spot rate to be rising in thefutureChapter 13 Exchange Rates, Business Cycles, and Macroeconomic Policy in the Open Economy 285C) Macroeconomic determinants of the exchange rate and net export demand1. Look at how changes in real output or the real interest rate are linked to the exchange rateand net exports, to develop an open-economy IS-LM model2. Effects of changes in output (income)a. A rise in domestic output (income) raises demand for goods and services, includingimports, so net exports declineData ApplicationHow do movements in the value of the dollar affect U.S. firms’ ability to compete internationally?Data and analysis of this issue are provided by Thomas Klitgaard and James Orr in their article“Evaluating the Price Competitiveness of U.S. Exports,” Federal Reserve Bank of New York,Current Issues in Economics and Finance, February 1998.Analytical Problem 4 looks at the effects of a supply shock on net exports.b. To increase purchases of imports, people must sell the domestic currency to buy foreigncurrency, increasing the supply of foreign currency, which reduces the exchange ratec. The opposite occurs if foreign output (income) rises(1) Domestic net exports rise(2) The exchange rate appreciates3. Effects of changes in real interest ratesa. A rise in the domestic real interest rate (with the foreign real interest rate held constant)causes foreigners to want to buy domestic assets, increasing the demand for domesticcurrency and raising the exchange rateb. The rise in the exchange rate leads to a decline in net exportsc. The opposite occurs if the foreign real interest rate rises(1) Domestic net exports rise(2) The exchange rate depreciatesD) Summary Table 16: Determinants of the exchange rate (real or nominal)1. A rise in domestic output (income) or the foreign real interest rate causes the exchange rateto fall2. A rise in foreign output (income), the domestic real interest rate, or the world demand fordomestic goods causes the exchange rate to riseE) Summary Table 17: Determinants of net exports1. A rise in domestic output (income) or the domestic real interest rate causes net exportsto fall2. A rise in foreign output (income), the foreign real interest rate, or the world demand fordomestic goods causes net exports to riseIII. The IS-LM Model for an Open Economy (Sec. 13.3)A) Only the IS curve is affected by having an open economy instead of a closed economy; the LMcurve and FE line are the same1. Note that we don’t use the AD-AS model because we need to know what happens to the realinterest rate, which has an important impact on the exchange rate2. The IS curve is affected because net exports are part of the demand for goods3. The IS curve remains downward sloping4. Any factor that shifts the closed-economy IS curve shifts the open-economy IS curve in thesame way286 Abel/Bernanke/Croushore • Macroeconomics, Sixth Edition5. Factors that change net exports (given domestic output and the domestic real interest rate)shift the IS curvea. Factors that increase net exports shift the IS curve up and to the rightb. Factors that decrease net exports shift the IS curve down and to the leftB) The open-economy IS curve1. The goods-market equilibrium condition isS d – I d=NX (13.4)a. This means that desired foreign lending must equal foreign borrowingb. Equivalently,Y =C d+I d+G + NX (13.5)c. This means the supply of goods equals the demand for goods and is derived using thedefinition of national saving, S d=Y – C d – G2. Plotting S d – I d and NX illustrates goods-market equilibrium (Figure 13.4; like text Figure 13.5)Figure 13.4a. Net exports can be positive or negativeb. The net export curve slopes downward, because a rise in the real interest rate increasesthe real exchange rate and thus reduces net exportsc. The S – I curve slopes upward, because a rise in the real interest rate increases desirednational saving and reduces desired investmentd. Equilibrium occurs where the curves intersectChapter 13 Exchange Rates, Business Cycles, and Macroeconomic Policy in the Open Economy 2873. To get the open-economy IS curve, we need to see what happens when domestic outputchanges (Figure 13.5; like text Figure 13.6)Figure 13.5a. Higher output increases saving, so the S – I curve shifts to the rightb. Higher output reduces net exports, so the NX curve shifts to the leftc. The new equilibrium occurs at a lower real interest rate, so the IS curve is downwardslopingC) Factors that shift the open-economy IS curve1. Any factor that raises the real interest rate that clears the goods market at a constant level ofoutput shifts the IS curve up and to the righta. An example is a temporary increase in government purchases (Figure 13.6; like textFigure 13.7)Figure 13.6b. The rise in government purchases reduces desired national saving, shifting the S – Icurve to the left, shifting the IS curve up and to the rightc. Anything that reduces desired national saving relative to investment shifts the IS curveup and to the right288 Abel/Bernanke/Croushore • Macroeconomics, Sixth Edition2. Anything that raises a country’s net exports, given domestic output and the domestic realinterest rate, will shift the open-economy IS curve up and to the right (Figure 13.7; like textFigure 13.8)Figure 13.7a. The increase in net exports is shown as a shift to the right in the NX curveb. This raises the real interest rate for a fixed level of output, shifting the IS curve up and tothe rightc. Three things could increase net exports for a given level of output and real interest rate(1) An increase in foreign output, which increases foreigners’ demand for domesticexports(2) An increase in the foreign real interest rate, which makes people want to buy foreignassets, causing the exchange rate to depreciate, which in turn causes net exports to rise(3) A shift in worldwide demand toward the domestic country’s goods, for example, asoccurs if the quality of domestic goods improvesAnalytical Problem 1 looks at the effect of trade barriers that reduce imports.3. Summary Table 18: International factors that shift the IS curvea. An increase in foreign output, the foreign real interest rate, or the demand for domesticgoods relative to foreign goods all shift the IS curve up and to the rightD) The international transmission of business cycles1. The impact of foreign economic conditions on the real exchange rate and net exports is oneof the principal ways by which cycles are transmitted internationally2. What would be the effect on Japan of a recession in the United States?a. The decline in U.S. output would reduce demand for Japanese exports, shifting theJapanese IS curve down and to the leftb. In a Keynesian model, or in the classical misperceptions model, this leads to recession inJapanc. In a classical (RBC) model, the decline in net exports wouldn’t affect Japanese output3. A similar effect could occur because of a shift in preferences (or trade restrictions) forJapanese goodsIV. Macroeconomic Policy in an Open Economy with Flexible Exchange Rates (Sec. 13.4)A) Two key questions1. How do fiscal and monetary policies affect a country’s real exchange rate and net exports?2. How do the macroeconomic policies of one country affect the economies of other countries?B) Three steps in analyzing these questions1. Use the domestic economy’s IS-LM diagram to see the effects on domestic output and thedomestic real interest rate2. See how changes in the domestic real interest rate and output affect the exchange rate andnet exports3. Use the foreign economy’s IS-LM diagram to see the effects of domestic policy on foreignoutput and the foreign real interest rateC) A fiscal expansion1. Look at a temporary increase in domestic government purchases using the classical (RBC)modela. The rise in government purchases shifts the IS curve up and to the right and the FE lineto the right (Figure 13.8; like text Figure 13.9)Figure 13.8b. The LM curve shifts up and to the left to restore equilibrium as the price level risesc. Both the real interest rate and output rise in the domestic countryd. Higher output reduces the exchange rate, while a higher real interest rate increases theexchange rate, so the effect on the exchange rate is ambiguouse. Higher output and a higher real interest rate both reduce net exports, supporting the twindeficits ideaNumerical Problems 3 and 4 illustrate the effects of an increase in government purchases on the exchange rate and net exports.2. How do these changes affect a foreign country’s economy?a. The decline in net exports for the domestic economy means a rise in net exports for theforeign country, so the foreign country’s IS curve shifts up and to the rightb. In the classical model, the LM curve shifts up and to the left as the price level rises to restoreequilibrium, thus raising the foreign real interest rate, but foreign output is unchangedc. In a Keynesian model, the shift of the IS curve would give the foreign country higheroutput temporarily3. In either the classical or Keynesian model, a temporary increase in domestic governmentpurchases raises domestic income (temporarily) and the domestic real interest rate, as in aclosed economya. It also reduces domestic net exports, so government spending crowds out bothinvestment and net exportsb. The effect on the exchange rate is ambiguousc. The foreign real interest rate and price level rised. In the Keynesian model, foreign output rises temporarilyD) A monetary contraction1. Look at a reduction in the domestic money supply in a Keynesian model2. Short-run effects on the domestic and foreign economies (Figure 13.9; like text Figure 13.10)Figure 13.9a. The domestic LM curve shifts up and to the leftb. In the short run, domestic output is lower and the real interest rate is higherc. The exchange rate appreciates, because lower output reduces demand for imports, thusreducing the supply of the domestic currency to the foreign exchange market, andbecause a higher real interest rate increases demand for the domestic currencyd. How are net exports affected?(1) The decline in domestic income reduces domestic demand for foreign goods,tending to increase net exports(2) The rise in the real interest rate leads to an appreciation of the domestic currency andtends to reduce net exports(3) Following the J curve analysis, assume the latter effect is weak in the short run, sothat net exports increasee. How is the foreign country affected?(1) Since domestic net exports increase, foreign net exports must decrease, shifting theforeign IS curve down and to the left(2) Output and the real interest rate in the foreign country decline(3) So a domestic monetary contraction leads to recession abroad3. Long-run effects on the domestic and foreign economiesa. In the long run, wages and prices in the domestic economy decline and the LM curvereturns to its original positionb. All real variables, including net exports and the real exchange rate, return to theiroriginal levelsc. As a result, the foreign IS curve returns to its original level as welld. Thus there is no long-run effect on any real variables, either domestically or abroade. This result holds in the long run in the Keynesian model, but it holds immediately inthe classical (RBC) model; monetary contraction affects only the price level even in the short runf. Though a monetary contraction doesn’t affect the real exchange rate, it does affect thenominal exchange rate because of the change in the domestic price levelg. Since enom =ePFor/P, the decline in P raises the nominal exchange rate by the samepercentage as the decline in the price level and the money supplyAnalytical Problem 2 uses a classical model to show what happens to capital flows in a classical model with circumstances similar to those of the United States in the 1980s.V. Fixed Exchange Rates (Sec. 13.5)A) Fixed-exchange-rate systems are important historically1. The United States has been on a flexible-exchange-rate system since the early 1970s2. But fixed exchange rates are still used by many countries3. There are two key questions we’d like to answera. How does the use of a fixed-exchange-rate system affect an economy andmacroeconomic policy?b. Which is the better system, flexible or fixed exchange rates?B) Fixing the exchange rate1. The government sets the exchange rate, perhaps in agreement with other countries2. What happens if the official rate differs from the rate determined by supply and demand?a. Supply and demand determine the fundamental value of the exchange rate (Figure 13.10;like text Figure 13.11)Figure 13.10b. When the official rate is above its fundamental value, the currency is said to beovervaluedc. The country could devalue the currency, reducing the official rate to the fundamentalvalued. The country could restrict international transactions to reduce the supply of its currencyto the foreign exchange market, thus raising the fundamental value of the exchange rate(1) If a country prohibits people from trading the currency at all, the currency is said tobe inconvertiblee. The government can supply or demand the currency to make the fundamental valueequal to the official rate(1) If the currency is overvalued, the government can buy its own currency(a) This is done by the nation’s central bank using its official reserve assets to buythe domestic currency in the foreign exchange market(b) Official reserve assets include gold, foreign bank deposits, and special assetscreated by agencies like the International Monetary Fund(c) The decline in official reserve assets is equal to a country’s balance of paymentsdeficitData ApplicationAn interesting examination of intervention by the U.S. government in the foreign exchange market is reported by Michael T. Belongia, “Foreign Exchange Intervention by the United States: A Review and Assessment of 1985–89,” Federal Reserve Bank of St. Louis Review,May/June 1992, pp. 32–51. Intervention appears to be more successful (there’s a larger changein the exchange rate) when both the Federal Reserve and a foreign central bank intervene on the same day.。

II.B. (P.125)
• 1. The first paragraph functions as a general introduction to the whole passage, through which we can get a glimpse of the great American writer, MarkTwain, who was not only adventurous,patriotic,romantic,and humorous,but also cynical,bitter and unhappy.
• 2. His experience immensely enriched his writing and helped him depict various characters successfully in his works.
II. (P. 124) A
• 3 The Celebrated Jumping Frog of Calaveras County. ’’
II. (P. 124) A
• 6. According to Twain, Americans should keep their daring and pioneering spirit by relaxing, resting,or staying away from the crazy struggle for success occasionally and keep their edges sharp.
• The author first makes the readers travel with Mark Twain to Nevada's Washoe region,where he succumbed to the epidemic of gold and silver fever,and accepted the job as a newspaper reporter due to his mining failure. From then on,he began working hard to gain regional fame as a newspaper reporter and humorist. Then the author makes the readers board with Mark Twain for San Francisco, then and now a hotbed of hopeful young writers.But because of some scathing columns he wrote, Mark Twain fled to the goldfields in the Sacramento Valley. There in Angels Camp he kept a notebook from which his first successful short story “The Celebrated Jumping Frog of Calaveras County” was born. Mark Twain’s national reputation was then well established as “the wild humorist of the Pacific slope. ”

课后阅读训练八Unit 2Period 4Ⅰ. 阅读理解AHarperCollins Publishers will translate mathematics textbooks from Chinese schools and publish them in Britain, according to its agreement with Shanghai Century Publishing Group.Under the agreement signed at the ongoing London Book Fair, some primary schools in Britain will use 36 books, including math textbooks, supplementary textbooks and teacher’s textbooks from Shanghai primary schools starting in September, sources with the Shanghai Municipal Education Commission said Wednesday. The textbooks will be translated from Chinese into English to deliver a complete math program for primary school students. Apart from publishing textbooks, Britain will also spread the Shanghai Teaching for Mastery Programme in the country. It is a four-year program backed by 41 million British pounds in funding announced by the British Department for Education in July 2016. “The collaboration can make a significant contribution to raising young people’s mathematics performance—which is essential to their future success in learning and in life, ”said Colin Hughes, Managing Director of Collins Learning.Shanghai students achieved good performance in reading, math andscience in the Programme for International Student Assessment in 2009 and 2012, drawing global attention to education in the Chinese city. A Shanghai-England teacher exchange started in 2014. In September 2014, 73 teachers and educational administrators from 45 English primary schools and relevant departments visited schools in Shanghai. Between November 2014 and March 2015, 61 mathematics teachers and researchers from Shanghai visited 48 English primary schools and performed teaching demonstrations. Communication between Chinese and British math teachers is conducive to sharing teaching experience and enhancing their teaching abilities, said Prof. Zhang Minxuan from Shanghai Normal University.In July 2016, Britain announced it would continue the exchange project and urged 8, 000 middle and primary schools in the country to lear n from Shanghai’s math education.【语篇概述】本文主要讲述英国部分小学将使用上海的数学教材。

Lessen 21. But these marks of wild country called to may father like the legendary siren song. Though the place was not pleasant or disagreeable, my father was deeply attracted to it precisely because of its unexplored, uncultivated natural state, and the challenge.2. "I'm afraid the day's going to catch us," I explained, wondering what great disaster might befall us if it did.As a little girl, I believed my father's words, and was genuinely afraid of the possible disaster--if we didn't hurry up, the day would catch us and terrible things might happen.3. ..from time to time he was halfheartedly sought for trial, though few crimes seemed to lead directly to his door.In this place, though the police wound make some effort without real earnest to investigate Watson and bring him to court, there seemed to be little concrete evidence to prove that he was responsible for certain illegal activities.4. The stranglehold Watson had over this section of Florida was not dissimilar to the unscrupulous activities of certain lawmen, other legal crooks, and even governors that our state was to suffer through its history.The control Watson had over this part of Florida was much similar to the dishonest or illegal activities of the law-enforcing officials and governors which Florida witnessed in the 20th century.5. There was the little shack, not the most gracious of living quarters, and there was a murderer for our nearest and only neighbor, about thirty miles away.Before the family built their own house, they lived in a shabby cabin at Gopher Key, close to the merciless Watson.6. King Richard in his gluttony never sat at a table more sumptuous than ours was three times a day...We had abundant food on the island, and even the meals enjoyed by King Ric hard, who was famous for his love of food, couldn’t possibly compare with ours.7. Despite the unrelenting heat, we were happy to be let off from our hours of school indoors, sessions which our mother kept every day, rain or shine.Although it was very hot outside in the sun, we were happy to be dismissed from my mother's sessions indoors. we would have to read and write with her every day no matter what the weather was like.Phrases1.in the line of Sherman’s march在谢尔曼将军的行军路线上2.a folding cot apiece每人一张轻便的帆布折叠床3.to replenish our food stock补充我们的食品4.as an added treat作为特别的款待5.free-roaming cattle自由放牧的牛群6.an infamous outlaw一个臭名昭著的亡命之徒7.business as usual一切照常8.to make regular runs to and fro定期往来运输9.a weather-boarded shack由隔板搭成的简陋的小屋10.under the care and interest of our entire family在我们全家人的悉心照料下Sentence1. It was an idyllic life ,and we lived close to our family and to the comforts and safety a small town could afford这是一种田园式的生活，我们和亲戚住的很近，享受着小镇生活所能给予我们的舒服和安全2. But papa was a man of enterprise; he realized that the untouched Ten Thousand Islands off the southwest coast of the sate were rich in soil for crops and in game for food但父亲是一个很有上进心的人，他知道佛罗里达州西南海岸的万岛群岛还没有被开发，那儿土壤肥沃，适于耕种，而且猎物充足，不必担心食物来源3. This third day out, and the days to come, found us in the unsettled wilds of Florida 出发后的第三天以及以后的日子里，我们都在佛罗里达无人居住的荒野中穿行4. Its underwater grasses looked like green ribbons, constantly unrolling, and the trees held thick sprays of wild orchids水里的水草就像绿色的丝带不断地伸展开来，野兰花一簇一簇地挂满了枝头5. The burly arms of oaks were huge with ferns and blooming bromeliads. Redbirds, tanagers and painted buntings flew back and forth across the trail, leaving a child with the impression that the woods were tossing with jewels以前这里经常发水的河滩岸边一丛丛地长满了乔叶栎，那些地面上铺着一层绿色的蕨类植物，乔叶栎粗壮的枝干上也覆盖着蕨类植物，俯生的凤梨科植物正在盛开。

第六课：Getting Along with NatureKeyComprehensionA 1. The similarity is in that the defenders of nature and wilderness and the defendersof industrialization base their arguments on the assumption that there are two distinct conditions, one natural and the other industrial. The dissimilarity is that the former opposes human encroachment and the latter want to make human encroachment complete.2. It means “unmixed” , “mere” and “unchanged”, respectively.3. Because pure nature cannot offer all the things that allow humans to livecomfortable and pleasantly.4. It implies that people are now suffering from such problems as pollution and thediminishing wilderness.5. He wants to exemplify that all creatures depend on nature and they all change it.6. Nature supplies us with what we need and at the same time, imposes restrictionon how much, and for how long we can get it.7. a. She makes and regulates natural laws.b. She deals out equal justice to all creatures.c. She joins all creatures and tri es to m ake th em live in h arm ony.8. The principle of justice.9. Y es. (1) the population (e.g. of woodpeckers) that an area can support, and (2)the maximum amount that can be contained (in the lynx’s stomach).10. No, because the author uses the words “we hope”.11. No. The author illustrates the complexity and adversary relationship man haswith nature as well as the need to better it.12. N.
