托福（TOEFL）考试阅读模拟试题（4） Questions 11-20 Philosophy in the second half of the 19th century was based more on biology and history than on mathematics and physics. Revolutionary thought drifted away from metaphysics and epistemology and shifted more towards ideologies in science, politics, and sociology. Pragmatism became the most vigorous school of thought in American philosophy during this time, and it continued the empiricist tradition of grounding knowledge on experience and stressing the inductive procedures of experimental science. The three most important pragmatists of this period were the American philosophers Charles Peirce (1839-1914), considered to be the first of the American pragmatists, William James (1842-1910), the first great American psychologist, and John Dewey (1859-1952), who further developed the pragmatic principles of Peirce and James into a comprehensive system of thought that he called “experimental naturalism”, or “instrumentalism”. Pragmatism was generally critical of traditional western philosophy, especially the notion that there are absolute truths and absolute values. In contrast, Josiah Royce (1855-1916), was a leading American exponent of idealism at this time, who believed in an absolute truth and held that human thought and the external world were unified. Pragmatism called for ideas and theories to be tested in practice, assessing whether they produced desirable or undesirable results. Although pragmatism was popular for a time in Europe, most agree that it epitomized the American faith in know-how and practicality, and the equally American distrust of abstract theories and ideologies. Pragmatism is best understood in its historical and cultural context. It arose during a period of rapid scientific advancement, industrialization, and material progress; a time when the theory of evolution suggested to many thinkers that humanity and society are in a perpetual state of progress. This period also saw a decline in traditional religious beliefs and values. As a result, it became necessary to rethink fundamental ideas about values, religion, science, community, and individuality. Pragmatists regarded all theories and institutions as tentative hypotheses and solutions.
2020年托福阅读模拟试题及答案（卷九） 托福阅读文本： The Native American peoples of the north Pacific Coast created a highly complex maritime culture as they invented modes of production unique to their special environment. In addition to their sophisticated technical culture, they also attained one of the most complex social organizations of any nonagricultural people in the world. In a division of labor similar to that of the hunting peoples in the interior and among foraging peoples throughout the world, the men did most of the fishing, and the women processed the catch. Women also specialized in the gathering of the abundant shellfish that lived closer to shore. They collected oysters, crabs, sea urchins, mussels, abalone, and clams, which they could gather while remaining close to their children. The maritime life harvested by the women not only provided food, but also supplied more of the raw materials for making tools than did fish gathered by the men. Of particular importance for the native tool kit before the introduction of metal was the wide knife made from the larger mussel shells, and a variety of cutting edges that could be made from other marine shells. The women used their tools to process all of the fish and marine mammals brought in by the men. They cleaned the fish, and dried vast quantities of them for the winter. They sun-dried fish when practical, but
中国石油英语测试（中石油模拟托福）的考后留言 为了感谢从网上和线下获得了很多关于准备这个考试的信息与帮助，我把自己的心得也留下来与后来者分享，祝福大家找工作的过程中好运连连！ 其实托福对我并不陌生，早在2001年10月就参加了ETS的托福考试，也取得了不错的成绩，但当时因为暑假中接受了以沙云龙为首的4大新东方名师的指导，所以考试准备显得轻松很多，更无找工作的压力了。 这一次为了中石油模拟托福，我差不多投入了3个月时间来复习准备，一是对我近3、4年来放弃英语学习的惩罚，二是托福考试如果依靠自己单打独斗，不仅入门很慢，各方面信息和资料不完整都是致命的，尤其对于考试中心的出题方式来说。 一、复习材料 大致来说，考试的复习资料包括3个方面。因为中石油是以95年改革后的托福真题为题库进行随即抽考，所以材料是最关键的第一步： 1、95年8月至2004年12月的所有国内及北美考试题（已在国内流传数年）：大约48套 2、中国大百科全书出版社的《TOEFL全真试题集》，有16套题，但11套与上述材料1重复，1套访真题重复无意义，所以只有4套 3、科学出版社的《托福历年全真试题》，有16套，其中4套与上述材料1重复，1套访真题重复无意义，所以只有11套 这就是大致的复习范围，当然这都只是真题了，材料1网上可下载文字和MP3，材料3需要到中关村书店类似的地方买，有8盘磁带，材料2已经很难买到了，也有8盘磁带，所以需要的人只能去找找有05年之前参加过真正的托福考试的人了。 另外还有很多的托福机经、新东方笔记，这对复习很有帮助，知道自己错在哪里，如何更正等。这些可以在太傻论坛和gter论坛找得到。 二、复习 从具体的复习来看， 1、听力是最关键的，也是最难伺候的，很多时候都是因为听力太低没有过线。所以要反复加强听力的练习，所有真题都能达到听到即能做题的地步最好。既然是题库，你就有很大几率碰上原题的时候。另外，从提高英语实力的角度来说，听写是一个比较好的练习方法，可以坚持尝试，特别是听得很乏味的时候。

2019托福阅读：模拟试题及答案解析（6） 【托福】 Although only 1 person in 20 in the Colonial period lived in a city, the cities had a disproportionate influence on the development of North America. They were at the cutting edge of social change. It was in the cities that the elements that can be associated with modern capitalism first appeared — the use of money and commercial paper in place of barter, open competition in place of social deference and hierarchy, with an attendant rise in social disorder, and the appearance of factories using coat or water power in place of independent craftspeople working with hand tools. "The cities predicted the future," wrote historian Gary. B. Nash, "even though they were but overgrown villages compared to the great urban centers of Europe, the Middle East and China." Except for Boston, whose population stabilized at about 16,000 in 1760, cities grew by exponential leaps through the eighteenth century. In the fifteen years prior to the outbreak of the War for independence in 1775, more than 200,000 immigrants arrived on North American shores. This meant that a population the size of Boston was arriving every year, and most of it flowed into the port cities in the Northeast. Philadelphia's population nearly doubted in those years, reaching about 30,000 in 1774, New York grew at almost the same rate, reaching about 25,000 by 1775. The quality of the hinterland dictated the pace of growth of the cities. The land surrounding Boston had always been poor farm country, and by the mid-eighteenth century it

2020年托福阅读模拟试题及答案（卷七） 托福阅读文本： Aviculturists, people who raise birds for commercial sale, have not yet learned how to simulate the natural incubation of parrot eggs in the wild. They continue to look for better ways to increase egg production and to improve chick survival rates. When parrots incubate their eggs in the wild, the temperature and humidity of the nest are controlled naturally. Heat is transferred from the bird's skin to the top portion of the eggshell, leaving the sides and bottom of the egg at a cooler temperature. This temperature gradient may be vital to successful hatching. Nest construction can contribute to this temperature gradient. Nests of loosely arranged sticks, rocks, or dirt are cooler in temperature at the bottom where the egg contacts the nesting material. Such nests also act as humidity regulators by allowing rain to drain into the bottom sections of the nest so that the eggs are not in direct contact with the water. As the water that collects in the bottom of the nest evaporates, the water vapor rises and is heated by the incubating bird, which adds significant humidity to the incubation environment. In artificial incubation programs, aviculturists remove eggs from the nests of parrots and incubate them under laboratory conditions. Most commercial incubators heat the eggs fairly evenly from top to bottom,
