1、【题目】We can begin our discussion of “population as global issue” with what most persons mean when they discuss “the population problem”: too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to “a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes.”
To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world’s population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.
1.Which of the following demographic growth pattern is most suitable for the long thin powder fuse analogy?
A.A virtually stable or slightly decreasing period and then a sudden explosion of population.
B.A slow growth for a long time and then a period of rapid, dramatic increase.
C.Too many people on earth and a few rapid increase in the number added each year.
D.A long period when death rates exceeds birthrates and then a short period with higher fertility and lower mortality.
2.During the first period of demographic history, societies were often in danger of extinction because___.
A.only one in ten persons could live past 40.
B.there was higher mortality than fertility in most places.
C.it was too dangerous to have babies due to the poor conditions.
D.our ancestors had little enthusiasm for more children.
3.Which statement is true about population increase?
A.There might be an increase of 2.2 billion persons from now to the year 2000.
B.About 50,000 babies are born every six hours at present.
C.Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.
D.The population increased faster between 8000BC and 1650 than between 1650 and the present.
4.The author of the passage intends to___.
A.warn people against the population explosion in the near future.
B.compare the demographic growth pattern in the past with that after 1650.
C.find out the cause for rapid increase in population in recent years.

如今，中国正步入老龄化社会，因此独生子女一代面临着巨大的工作和生活压力。中国政府开始适当调整计划生育政策，允许一些家庭在特殊情况下生育二胎。但调查显示，很多夫妻迫于不断加重的经济压力，放弃生育二胎。因此，要从根本上解决老龄化的问题不能依靠出生率的上升，最有效的办法是建立有效的社会保障制度。
答案：
Nowadays, China is stepping into the aging society. Therefore, the only-child generation is facing enormous pressure both from work and life. The Chinese government has begun to adjust the familyplanning policy and allows some families to have a second child under certain circumstances. However, the survey shows thatsome couples abandon to have a second child due to the increasing financial burden. Thus, in order to solve the aging problem,the basic thing is not relying on the increase of birth rate. The best solution is to establish an effective social security system.
