作为20世纪最伟大的物理学家之一，爱因斯坦对物质世界的思考和认识是深入的。他的狭义相对论成功地揭示了能量与质量之间的关系，解决了长期存在的恒星能源来源的难题。其广义相对论也解决了一个天文学上多年的不解之谜——水星近日点的进动，并推断出后来被验证了的光线弯曲现象。但就是这位蜚声全球的科学家，在20世纪30年代收到以色列当局诚挚邀请他担任以色列总统的信时，断然拒绝了邀请。能够成为犹太国的总统，无疑是爱因斯坦人生的又一项辉煌成就。但出乎人们意料的是，爱因斯坦毫不犹豫地拒绝了。他说：“我整个一生都在同客观物质打交道，既缺乏天生的才智，也缺乏经验来处理行政事务以及公正地对待别人。所以，本人不适合担当如此高官重任。”可以说，爱因斯坦是位。

Urbanization

Until relatively recently, the vast majority of human beings lived and died without ever seeing a city. The first city was probably founded no more than 5,500 years ago. 【1】. 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. 【2】 .The process of urbanization ——the migration (迁移) 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 1990, fewer than 40% of Americans lived in urban areas. Today, over 82% of Americans live in cities. Only about 2% live on farms. 【3】 .

Large cities were impossible until agriculture became industrialized. Even in advanced agricultural societies. It took about ninety-five people on farms to feed five people in cities. 【4】 . 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 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. 【5】 . 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.

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 become urban societies.

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

F. Modernization drew people to the cities and made farmers more productive.

G. Modern cities have destroyed social relations and the health of human beings.
