1998年Passage 4
 
　　Emerging from the 1980 census is the picture of a nation developing more and more regional competition, as population growth in the Northeast and Midwest reaches a near standstill.
 
　　This development - and its strong implications for US politics and economy in years ahead - has enthroned the South as America's most densely populated region for the first time in the history of the nation's head counting.
 
　　Altogether, the US population rose in the 1970s by 23.2 million people - numerically the third largest growth ever recorded in a single decade. Even so, that gain adds up to only 11.4 percent, lowest in American annual records except for the Depression years.
 
　　Americans have been migrating south and west in larger number since World War II, and the pattern still prevails.
 
　　Three sun belt states - Florida, Texas and California - together had nearly 10 million more people in 1980 than a decade earlier. Among large cities, San Diego moved from 14th to 8th and San Antonio from 15th to 10th - with Cleveland and Washington.DC, dropping out of the top 10.
 
　　Not all that shift can be attributed to the movement out of the snow belt, census officials say, Nonstop waves of immigrants played a role, too - and so did bigger crops of babies as yesterday's "baby boom" generation reached its child bearing years.
 
　　Moreover, demographers see the continuing shift south and west as joined by a related but newer phenomenon: More and more, Americans apparently are looking not just for places with more jobs but with fewer people, too. Some instances-
　　　　
● Regionally, the Rocky Mountain states reported the most rapid growth rate - 37.1 percent since 1970 in a vast area with only 5 percent of the US population.
　　　　
●Among states, Nevada and Arizona grew fastest of all: 63.5 and 53.1 percent respectively. Except for Florida and Texas, the top 10 in rate of growth is composed of Western states with 7.5 million people - about 9 per square mile.
 
The flight from overcrowdedness affects the migration from snow belt to more bearable climates.
 
Nowhere do 1980 census statistics dramatize more the American search for spacious living than in the Far West. There, California added 3.7 million to its population in the 1970s, more than any other state.
 
In that decade, however, large numbers also migrated from California, mostly to other parts of the West. Often they chose - and still are choosing - somewhat colder climates such as Oregon, Idaho and Alaska in order to escape smog, crime and other plagues of urbanization in the Golden State.
 
As a result, California's growth rate dropped during the 1970s, to 18.5 percent - little more than two thirds the 1960s' growth figure and considerably below that of other Western states.

66. The word "demographers" (Line 1, Paragraph 7) most probably means _____ .
[A] people in favor of the trend of democracy
[B] advocates of migration between states
[C] scientists engaged in the study of population
[D] conservatives clinging to old patterns of life

[答案] C

[解題思路]

　　本題對應的信息為"Moreover, demographers see the continuing shift south and west as joined by a related but newer phenomenon"( 此外，人口統(tǒng)計學家發(fā)現(xiàn)，向南部和西部的不斷遷移還伴隨著一種與此相關卻又與以往不同的現(xiàn)象) 。乍一看這個句子似乎還不能幫助解題，但是文章從第一段就出現(xiàn)了很多包含相關信息的關鍵詞如1980 census 和population growth等。而從上面這句話中可以看出來，這種人代表的觀點是比較官方和權威的，因此可以推斷他們就是從事人口研究的科學家。實際上，"demography"這個詞的意思就是"人口統(tǒng)計學"的意思，而"demographer"是有此引申的一個詞語。
