12、ulation as global issue” with what most persons mean”: too many people on earth and a too rapid increase inWe can begin our discussion of when they discuss“the population problemthe number added each year. The facts are not in dispute, It was quite right to employ the analogy that liken ed demograph

13、ic growth to“ a long, thin powder fuse that burns steadily and haltinglyuntil 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 co

14、mparatively 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 place

15、s, 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 b

16、irthrates. 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 p

17、opulation 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.

18、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 isestimatedthat by the year 2000 there will be 6.2 billion people throughout t

19、he 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

20、added every sixhours. 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 lon

A long period when death rates exceeds birthrates and then a short period with higher fertility and lower mortality.2. Duri ng the first p eriod of demogra phic

One Janu

26、ary, I had to officiate at two fun erals on successive days for two elderly wome n in my com mun ity. Both had died "full of years," as the Bible would say; both yielded to the no rmal weari ng out of the body after a long and full life. Their homes happened to be n ear each other, so I p

27、aid con dole nee （吊唁）calls on the two families on the same after noon.At the first home, the son of the deceased （已故的）woman said to me, "If only I had sent my mother to Florida and gotte n her out of this cold and snow, she would be alive today. It's my fault that she died." At the sec

28、 ond home, the son of the other deceased woma n said, "If only I had n't in sisted on my mother's going to Florida, she would be alive today. That long air plane ride, the abrupt cha nge of climate, was more tha n she could take. It's my fault that she's dead."When things d

29、on't turn out as we would like them to, it is very temp ti ng to assume that had we done things differe ntly, the story would have had a happier ending. Priests know that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out badly, they beli

30、eve that the oppo site course - kee ping Mother at home, postponing the op eratio n C would have turned out better. After all, how could it have turned out any worse?There seem to be two eleme nts in volved in our readi ness to feel guilt. The first is our p ress ing n eed to believe that the world

31、makes sen se, that there is a cause for every effect and a reas on for everyth ing that happens. That leads us to find p atter ns and connections both where they really exist and where they exist only in our min ds.The sec ond eleme nt is the no ti on that we are the cause of what happens, esp ecial

32、ly the bad things that happen. It seems to be a short ste p from believi ng that every event has a cause to believi ng that every disaster is our fault. The roots of this feeli ng may lie in our childhood. Psychologists sp eak of the infan tile myth of omnipotence （ 萬(wàn)能）.A baby comes to thi nk that t

He cries, and some one comes to atte nd to him. When he is hun gry, people feed him, and whe n he is wet, people cha nge him. Very ofte n, we do

34、 not compi etely outgrow that infan tile no ti on that our wishes cause things to happen.6. What is said about the two deceased elderly wome n?A.

An estimated 6 millio n televisio ns and compu ters are stocked in California homes, and an additi onal 6,000 to 7,000 compu ters become outdated every day. The mach ines contain high levels of lead and other hazardous substances, and are already bann

Used in almost all video mon itors and televisi ons, those devices contain four to eight pounds of lead each

The fees wouldgo toward sett ing up recycli ng p rograms, p rovidi ng grants to non-p rofit age ncies that reuse the tubes and reward ing manufacturers that en courage recycli ng.A sep arate bill by Los An geles-area Sen ator Gloria Romero would require high-tech manu facturers to deve lop p rogra
