During his administr

2、ation he immeasurably enlarged the power of the presidency. “The President is the direct representative of the American people,“ he lectured the Senate when it opposed him. “He was elected by the people, and is responsible to them. “ With this declaration, Jackson redefined the character of the pres

3、idential office and its relationship to the people.During Jacksons second term, his opponents had gradually come together to form the Whig party.

21、ature, each of which permits a precise measurement, are in concurrent use: the Fahrenheit, Celsius, and Kelvin scales. These three different temperature scales were each developed by different people and have come to be used in different situations.The scale that is most widely used by the general p

22、ublic in the United States is the Fahrenheit scale. In 1714, Daniel Gabriel Fahrenheit, a German physicist who was living in Holland and operating an instrument business, developed a mercury-in-glass thermometer and the temperature scale that still carries his name. His original scale had two fixed

23、points: 0 was the lowest temperature that he could achieve in a solution of ice, water, and salt, and 96 was what he believed was the normal temperature of the human body (though this was later determined to be 98.6). Based on this scale, he calculated that the freezing point (or ice point) of water

24、 was 32; in later studies, it was determined that the boiling point of water (the steam point) was 212. The Fahrenheit scale came to be accepted as the standard measure of temperature in a number of countries, including Great Britain, and from there it was spread to British colonies throughout the w

25、orld. Today, however, the United States is the only major country in the world that still uses the Fahrenheit scale.The scale that is in use in many other countries is the Celsius scale. Anders Celsius (1701-1744), a Swedish astronomer, developed a thermometer in 1741 that based temperatures on the

26、freezing and boiling temperatures of water. On the thermometer that Celsius developed, however, 0 was used to indicate the boiling temperature of water, and 100 was used to indicate the freezing temperature of water. After his death, the scale was reversed by a friend, the biologist Carl yon Linne(1

27、707-1748), who achieved acclaim for his development of the Linnean classification system for plants and animals. On the new scale after the reversal by yon Linne, 0 indicated the freezing temperature of water, and 100 indicated the boiling temperature of water. At around the same time that Celsius a

28、nd yon Linne were working on their thermometer in Sweden, a similar thermometer was being developed in France. After the French Revolution, the scale developed in France was adopted as part of the metric system in that country under the name centigrade, which means “a hundred units“ and from there i

29、t spread worldwide. In 1948, an international agreement was made to rename the centigrade scale the Celsius scale in honor of the scientist who was first known to use a 100-degree scale, though it should be remembered that the scale that Celsius actually used himself was the reverse of todays scale.

31、indicated the temperature at which water freezes.(2).The word “fixed“ in paragraph 2 is closest in meaning to _.（分数：1.00）A.orderedB.repairedC.establishedD.attache(3).What is stated in the passage about the temperature scale developed by Fahrenheit? _（分数：1.00）A.On it, 0 was the freezing point of wate

32、r.B.It was based on the lowest and highest temperatures that he could achieve with a mixture of salt and water.C.On it, 100 was the boiling point of water.D.It was based on an inaccurate understanding of the normal temperature of the human body.(4).The word “it“ in paragraph 2 refers to _.（分数：1.00）A

33、.the Fahrenheit scaleB.temperatureC.a number of countriesD.the world(5).The author refers to “many other countries“ in paragraph 3 in order to _.（分数：1.00）A.introduce a discussion of the areas of the world where the Celsius scale is usedB.argue for the need for a standard measure of temperature throu

41、perature of a solution of saltwater and ice.（分数：1.00）填空项 1:_三、Passage 3(总题数：1，分数：13.00)Migration from AsiaThe Asian migration hypothesis is today supported by most of the scientific evidence. The first “hard“ data linking American Indians with Asians appeared in the 1980s with the finding that India

42、ns and northeast Asians share a common and distinctive pattern in the arrangement of the teeth. But perhaps the most compelling support for the hypothesis comes from genetic research. Studies comparing the DNA variation of populations- around the world consistently demonstrate the close genetic rela

43、tionship of the two populations, and recently geneticists studying a virus sequestered in the kidneys of all humans found that the strain of virus carried by Navajos and Japanese is nearly identical, while that carried by Europeans and Africans is quite different.The migration could have begun over

44、a land bridge connecting the continents. During the last Ice Age 70,000 to 10,000 years ago, huge glaciers locked up massive volumes of water and sea levels were as much as 300 feet lower than today. Asia and North America were joined by a huge subcontinent of ice-free, treeless grassland,750 miles

45、wide. Geologists have named this area Beringia, from the Bering Straits. Summers there were warm, winters were cold, dry and almost snow-free. This was a perfect environment for large mammals-mammoth and mastodon, bison, horse, reindeer, camel, and saiga (a goatlike antelope). Small bands of Stone A

46、ge hunter-gatherers were attracted by these animal populations, which provided them not only with food but with hides for clothing and shelter, dung for fuel, and bones for tools and weapons. Accompanied by a husky-like species of dog, hunting bands gradually moved as far east as the Yukon River bas

47、in of northern Canada, where field excavations have uncovered the fossilized jawbones of several dogs and bone tools estimated to be about 27,000 years old.Other evidence suggests that the migration from Asia began about 30,000 years ago-around the same time that Japan and Scandinavia were being set

48、tled. This evidence is based on blood type. The vast majority of modern native Americans have type O blood and a few have type A, but almost none have type B. Because modern Asian populations include all three blood types, however, the migrations must have begun before the evolution of type B, which

49、 geneticists believe occurred about 30,000 years ago.By 25,000 years ago human communities were established in western Beringia, which is present-day Alask a. But access to the south was blocked by a huge glacial sheet covering much of what is today Canada. How did the hunters get over those 2,000 miles of deep ice? The argument
