10．讲物体从平滑、规则状态转变到不规则状态的，这篇阅读也很长，详细意思也记得不是很清楚了。也就不误导大家了。物理方面的，主要是如何理解，生词倒是没有遇到太多。 11．讲热带生物多样性的形成原因，提出了三种解释，一种是“生存压力说”（我自己的翻译，主要是根据里面的pressure来的），一种是气候说，说是冰川气候之后形成了这一情况，最后那个记得不太清楚了。但是文章最后说了前面两种都没有找出证据来支持，只有第三个解释才可能是正确的。大致好像就是这样的，这篇阅读最后10道题出现的，当时时间已经不多，不过好在它比较短，也不太难理解，结构也很清晰，相信大家碰到了应该没有问题。 热带雨林机经资料(后面加了点更新)
(2004-7-16) 1.关于热带雨林生物多样性的，跟着提出了三种解释，第1个解释说是因为为了防止被eater吃了，所以要不断的变化发展，讲rain forest plant diversification的产生新的种类以保护自己。。第2个好象叫什么refuge（意思相近），讲是最近的那一次北半球的ice age，使得雨林diminish了，然后arid area使得跟多的物种被merge到雨林里了，第3个是什么忘了。。问题是：主题，关于第2点的两题，关于第1点的一题
热带雨林植物多样性的解释结构：此多样性现象引起关注——依次介绍解释该现象的三个现行观点（参考前面JJ）——评价三个解释的正确性（其中前两者已有证据削弱，而最后一个因为尚无可以削弱的证据而显得plausible）
题目：重点考了第二个解释，与其有关的归纳题、正改善(支持类)的逻辑题 (05/27/2004) 热带雨林植物多样性
热带雨林植物多样性三个原因：1.植物有毒使得动物有抗体，又导致植物产生新的变化，互相的作用（interact）使它们变化多样。2.冰河时期，降雨减少，地球被分成一块一块，这块地就是refugee（避难地），物种繁荣，多样化。(有题, 问哪个WEAKEN这个理论) 3.地震地址运动，火山等导致。
作者对前两个找到反驳观点，第三点没有，则最可能是原因。)(问主题:是介绍不同的理论about ecosystem phenomena, 不时理论in dealing with ecosystem situation) (2002.1) 2、RAINFORCE的多种PLANT如何形成-有三种形成理论，问题全针对第二种提出的。热带雨林植物多样性的三种解释, forest中plants diversity的问

In the two decades between 1910 and 1930, over ten percent to the Black population of the United States
left the South, where the preponderance of the Black population had been located, and migrated to northern (5) states, with the largest number moving, it is claimed, between 1916 and 1918. It has been frequently assumed, but not proved, that the majority of the migrants in what has come to be called the Great Migration came from rural areas and were motivated by two concurrent (10) factors: the collapse of the cotton industry following the boll weevil infestation, which began in 1898, and increased demand in the North for labor following the cessation of European immigration caused by the outbreak of the First World War in 1914. This assump- (15) tion has led to the conclusion that the migrants’ subse- quent lack of economic mobility in the North is tied to rural background, a background that implies unfamil- iarity with urban living and a lack of industrial skills. But the question of who actually left the South has (20) never been rigorously investigated. Although numerous investigations document an exodus from rural southern areas to southern cities prior to the Great Migration. no one has considered whether the same migrants then moved on to northern cities. In 1910 over 600,000 (25) Black workers, or ten percent of the Black work force, reported themselves to be engaged in “manufacturing and mechanical pursuits,” the federal census category roughly encompassing the entire industrial sector. The Great Migration could easily have been made up entirely (30) of this group and their families. It is perhaps surprising to argue that an employed population could be enticed to move, but an explanation lies in the labor conditions then prevalent in the South. About thirty-five percent of the urban Black popu- (35) lation in the South was engaged in skilled trades. Some were from the old artisan class of slavery-blacksmiths. masons, carpenters-which had had a monopoly of certain trades, but they were gradually being pushed out by competition, mechanization, and obsolescence, (40) The remaining sixty-five percent, more recently urban- ized, worked in newly developed industries---tobacco. lumber, coal and iron manufacture, and railroads. Wages in the South, however, were low, and Black workers were aware, through labor recruiters and the (45)Black press, that they could earn more even as unskilled workers in the North than they could as artisans in the South. After the boll weevil infestation, urban Black workers faced competition from the continuing influx of both Black and White rural workers, who were driven (50) to undercut the wages formerly paid for industrial jobs. Thus, a move north would be seen as advantageous to a group that was already urbanized and steadily employed, and the easy conclusion tying their subse- quent economic problems in the North to their rural background comes into question. 31. The author indicates explicitly that which of the following records has been a source of information in her investigation? (A) United States Immigration Service reports from 1914 to 1930 (B) Payrolls of southern manufacturing firms between 1910 and 1930 (C) The volume of cotton exports between 1898 and 1910 (D) The federal census of 1910（D）
(E) Advertisements of labor recruiters appearing in southern newspapers after 1910 32. In the passage, the author anticipates which of the following as a possible objection to her argument? (A) It is uncertain how many people actually migrated during the Great Migration. (B) The eventual economic status of the Great Migration migrants has not been adequately traced. (C) It is not likely that people with steady jobs would have reason to move to another area of the country. (D) It is not true that the term “manufacturing and mechanical pursuits” actually encompasses the entire industrial sector.
（C）
(E) Of the Black workers living in southern cities, only those in a small number of trades were threatened by obsolescence. 33. According to the passage, which of the following is true of wages in southern cities in 1910? (A) They were being pushed lower as a result of increased competition. (B) They had begun t to rise so that southern industry could attract rural workers. (C) They had increased for skilled workers but decreased for unskilled workers. (D) They had increased in large southern cities but decreased in small southern cities.
（A）
(E) They had increased in newly developed industries but decreased in the older trades. 34. The author cites each of the following as possible influences in a Black worker’s decision to migrate north in the Great Migration EXCEPT (A) wage levels in northern cities (B) labor recruiters (C) competition from rural workers (D) voting rights in northern states（D）
(E) the Black press 35. It can be inferred from the passage that the “easy conclusion” mentioned in line 53 is based on which of the following assumptions? (A) People who migrate from rural areas to large cities usually do so for economic reasons. (B) Most people who leave rural areas to take jobs in cities return to rural areas as soon as it is financially possible for them to do so. (C) People with rural backgrounds are less likely to succeed economically in cities than are those with urban backgrounds. (D) Most people who were once skilled workers are not willing to work as unskilled workers.
（C）
(E) People who migrate from their birthplaces to other regions of country seldom undertake a second migration. 36. The primary purpose of the passage is to (A) support an alternative to an accepted methodology (B) present evidence that resolves a contradiction (C) introduce a recently discovered source of information (D) challenge a widely accepted explanation（D）
(E) argue that a discarded theory deserves new attention not really... Great Migration是个很大文化背景,就像中国的文革一样,可以出很多文章 |
