16、 有些不認(rèn)識(shí)的或無法確定的， 如 N) worth(adj./n.) ，可先擱置，不要過度糾纏。綜合解題將選項(xiàng)分類之后， 就得從文章中來尋找對(duì)應(yīng)的線索了。選項(xiàng)與文章匹配的因素有兩個(gè)，第一是詞性，第二是詞義。所以在讀文章時(shí)，要通過各種手段來確定空格的詞性與意義。(一) 確定詞性，確定選項(xiàng)的選擇范圍1) 關(guān)于動(dòng)詞的判斷前后都是名詞短語，中間是動(dòng)詞 。根據(jù)一句 (包括從句 )有且只有一個(gè)謂動(dòng)的原則，其它地方如無謂語動(dòng)詞，則需要謂語動(dòng)詞 ;反之則不需要謂語動(dòng)詞。學(xué)習(xí)資料學(xué)習(xí)資料收集于網(wǎng)絡(luò)，僅供參考Nowadays, weather experts are able to forecast when a

21、一看搭配：主謂賓、主系表與修飾 詞直接的搭配關(guān)系決定著詞的意義。所以先看它被誰修飾， 與誰形成主謂賓關(guān)系。 看一種關(guān)系不行就看另一個(gè)， 靈活處之。This strange 47 happens every five to eight years.strange 修飾 47 ，也許看不出來是什么， 再看 47 與 happen 形成主謂關(guān)系，能夠發(fā)生的是什么最好的當(dāng)然是現(xiàn)象。47.

22、the Peru current flowing in from the east to warm up by as much as 5 °C.此句有一個(gè)狀語從句， as 表示的時(shí)間或因果關(guān)系，是重要的解題線索。風(fēng)的什么減少，溫度就上升，當(dāng)然是風(fēng)的速度或風(fēng)力。48.

On that day, for fifteen million dollars, the United States purchased from France 875,000 square miles of territory. After Robert R. Livingston, an American who repres

34、ented President Jefferson in France, signed his name to the treaty, he rose, shook hands with James Monroe and Marbois, the Frenchman representing Napoleon and remarked, "We have lived long, but this is the noblest work of our lives. " As we glance backward upon this important event in his

35、tory, we must agree that the signing of the treaty for the purchase of Louisiana was probably the most important event in Thomas Jefferson's administration. Without the acquisition of this territory, the United States would most probably have not developed into the powerful nation which it is to

36、day.What Causes Led to Purchase of the Louisiana Territory Until 1763, Louisiana had been a possession of France, but inthat year it was given to Spain to repay an old debt. Twenty years later in Paris, the treaty ending the American Revolution was signed between the United States and Great Britain.

37、 One of the terms of this treaty was that the western border of the United States was to stretch to the Mississippi River. Immediately settlers and pioneers crossed westward over the Allegheny Mountains to clear the territory and establish farms. Since roads were scarce and difficult to travel, the

38、products of these farmers had to be shipped on the waterways leading to the Mississippi River and then down this great stream to New Orleans. At this port city, the produce was transferred to larger ocean-going vessels and transported to markets on the Eastern Seaboard or to Europe. However, Spain&#

39、39;s ownership of both shores of the river for at least two hundred miles north of New Orleans permitted this foreign nation to control the trademoving on the Mississippi. As a monarchy ( 君主政體 ) ，the Spanish government distrusted the rising spirit of democracy in the United States, especially the mu

40、ch freer expression of democracy that existed among學(xué)習(xí)資料學(xué)習(xí)資料收集于網(wǎng)絡(luò)，僅供參考the western farmers. This distrust of democracy resulted in the desire ofthe Spanish to deny the use of the great river to any Americans. Thereaction was instantaneous (瞬間的) and furious, western farmers raisedtheir voices to protes

41、t and the United states sent John Jay to Madrid todiscuss this matter. In 1795 this conflict was settled. Spain consented toallow citizens of the United States the right to use the lower MississippiRiver and also the "right of deposit" at New Orleans, the right of depositpermitted American

42、 farmers, without a duty charge, to remove theirproducts from smaller boats at New Orleans after having navigated down the Mississippi, and then to transfer the agricultural commodities to larger ocean-going vessels.For the succeeding five years this agreement was observed and little conflict existe

43、d. On October 1, 1800, however, Spain signed a treaty giving the ownership of the Louisiana territory back to France. The news of this treaty did not reach Jefferson until May of the following year. As soon as he became aware of the change in ownership of the territory, Jefferson realized that this

44、was part of a plan by which Napoleon hoped to establish France as a great power in the New World. Although Napoleon still permitted Spain to remain in control of the port of New Orleans, the future threat to the navigation rights of the western farmers still remained. At any moment, Napoleon might s

45、end troops to the "Gateway" and forbid Americans to use it for navigation. This would affect almost forty per cent of the total export trade of the United States. By April 1802 Jefferson's concerns in this matter became even more intense. Napoleon had shipped armed forces to Santo Domi

46、ngo to suppress the uprising. Once this had been accomplished, the troops were under orders to take possession of Louisiana with its key port city of New Orleans. On the eighteenth of that month the President wrote his now-famous letter to the American Minister to France, Robert R. Livingston.There

47、is one place on the globe, one single spot, the possessor of which is our natural and habitual enemy. It is New Orleans through which the produce of three eighths of our territory must pass to學(xué)習(xí)資料學(xué)習(xí)資料收集于網(wǎng)絡(luò)，僅供參考market. . . it seals the union of two nations who in conjunction can maintain exclusive po

48、ssession of the ocean. From that moment we must marry ourselves to the British fleet and nation.Seven months later Jefferson learned that the Spanish officials at New Orleans had suspended( 暫不實(shí)行 ) the right of deposit. Immediately westernfarmers protested. Many demanded immediate action. Others pres

49、sed for a declaration of war. The Federalists in the East who opposed Jefferson sided with those who wished to declare war, in order to split the ranks of his followers. In January 1803, Congress appropriated twomillion dollars "to defray (支付 ) expenses to help improve relationsbetween the Unit

50、ed States and foreign nations. " Jefferson asked JamesMonroe to sail for France to resolve the difficulty. Monroe was instructedto negotiate for the purchase of New Orleans and Florida. He waspermitted to offer 50,000,000 francs for this concession of territory. Ifthis offer were refused, then

51、an alternative offer of 37,500,000 francs wasto be made for New Orleans alone. A third alternative to be used in thenegotiation was to insist upon the permanent right of deposit at NewOrleans and navigation along the lower Mississippi. If all three offerswere rejected by Napoleon, Monroe and Livings

52、ton were instructed tonegotiate an alliance with the British Government "not to make anypeace with France. "Why Napoleon Sold LouisianaEvents favored the United States. Napoleon had transported 35,000 troops to wipe out the rebellion in Santo Domingo, but yellow fever and the rebels did aw

53、ay with most of the French troops. With this disaster Napoleon's visions of expanding in the mainland at New Orleans vanished. He also recognized he inevitability of a conflict with Great Britain. How could he hope to keep Louisiana, thousands of miles away across the Atlantic, as long as Britain was "Empress of the Seas"? The revenue that the sale of Louisiana would bring toFrance was a temptation to Napoleon, whose treasury was almost depleted ( 消耗 ).
