根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中的两项为多余选项。UrbanizationUntil relatively recently, the vast majority of human being lived and died without ever seeing a city. The first city was probably founded no more than 5,500 years ago.___16___In fact, nearly everyone lived on farms or in tiny rural (乡村的) villages. It was not until the 20th century that Great Britain became the first urban society in history—a society in which the majority of people live in cities and do not farm for a living.Britain was only the beginning.___17___The process of urbanization—the migration (迁徙) of people from the countryside to the city—was the result of modernization, which has rapidly transformed how people live and where they live.In 1900, fewer than 40% of Americans lived in urban areas. Today, over 82% of Americans live in cities. Only about 2% live on farms.___18___Large cities were impossible until agriculture became industrialized. Even in advanced agricultural societies, it took about ninety­five people on farms to feed five people in cities.___19___Until modern times, those living in cities were mainly the ruling elite (精英) and the servants, laborers and professionals who served them. Cities survived by taxing farmers and were limited in size by the amount of surplus（过剩）food that the rural population produced and by the ability to move this surplus from farm to city.Over the past two centuries, the Industrial Revolution has broken this balance between the city and the country.___20___Today, instead of needing ninety­five farmers to feed five city people, one American farmer is able to feed more than a hundred non­farmers.

A. That kept cities very small.

B. The rest live in small towns.

C The effects of urban living on people should be considered.

D. Soon many other industrial nations became urban societies.

E. But even 200 years ago, only a few people could live in cities.

【答案】16. E    17. D    18. B    19. A    20. F
【解析】
本文是说明文。文章的主题是城市化。文章讲述了过去城市规模小，农民人口多，到现代化之后，农民人口变少，但农业产量反而增加，更多的人住在城市，体现了社会的变迁。
【16题详解】
根据前一句“The first city was probably founded no more than 5,500 years ago”可知，此处讲的是以前城市的情况，即第一座城市仅仅是5500年才出现的，甚至200年前，也只有很少一部分人生活在城市中。其他几个选项没有关于以前城市的描述。故选择E。
【17题详解】
根据前一句的“Britain was only the beginning”可知，英国只是个开始，关键词beginning，因此后面出现的是soon，句意：英国只是个开始，很快，其他工业国家也变成了城市化社会。故选择D。
【18题详解】
 根据前一句的“Today, over 82% of Americans live in cities. Only about 2% live on farms”可知，目前，超过82%的美国人住在城市，只有2%的人住在农场，在讲完了82%和2%之后，还有剩下的人呢，住在哪里呢？因此可以推断出，下一句讲述的是the rest即，其余的人住在什么地方。因此，选择B，其余的人住在城镇里。故选择B。
【19题详解】
根据前一句的“It took about ninety-five people on farms to feed five people in cities”可知，要有95个人在农场里工作，才能养活5个城市里的人，因此城市里居住的人肯定要少，规模肯定很小，因此选择A项，这种原因导致了城市规模很小。故选择A。
【20题详解】
根据后面的“Today, instead of needing ninety-five farmers to feed five city people, one American farmer is able to feed more than a hundred non-farmers”可知，现在一个美国人在农场里工作，可以养活100多个非农美国人，因此现代化让农民更加多产，让更多的人可以居住在城市里。故选择F。
【点睛】
定位选项，明确各备选选项的含义，抓住其关键词语，根据文章整体结构与具体内容，将选项填入文中，填写时尤为注意各选项中出现的句子衔接手段及句中的衔接标志词。在定位选项时，要特别注意空格上下段的写作内容，以及空格上段尾句和下段首句的结构和意义。将所选项放入空白处，看看是否与上下文构成语义及逻辑上的直接关系，是否符合该处语境。能否承接前后的写作线索。使文章无论内容还是衔接上都能做到通顺。比如第3小题根据前一句的“Today, over 82% of Americans live in cities. Only about 2% live on farms”目前，超过82%的美国人住在城市，只有2%的人住在农场，在讲完了82%和2%之后，还有剩下的人呢，住在哪里呢？因此可以推断出，下一句讲述的是the rest即，其余的人住在什么地方。因此，选择B，其余的人住在城镇里。
