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 populate 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 numbers 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 D. C. , 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 reproved 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 state 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. We can see from the available statistics that ____________.
A. California was once the most thinly populated area in the whole US
B. the top 10 states in growth rate of population were all located in the West
C. cities with better climates benefited unanimously from migration
D. Arizona ranked second of all states in its growth rate of population

TEXT A E-commerce Is Here to Stay Neither the absolute level of Internet sales nor the growth rate tells the whole story, but this year e-commerce became a mainstream retail channel. You don’t have to look far to find reasons for pessimism, however: a sluggish economy, the aftershocks of Sept. 11, and the problems of particular Web retailers. And even if consumer e-tailers don’t post big numbers during the holiday shopping season, Web retailers have done a lot of work behind the scenes to make the Internet a viable channel overall. Web commerce now has a more reasonable set of expectations. Many a dot-com company boasted that it would put traditional stores out of business. Remember Web grocers Like many of their dot-com peers, those who went it alone folded or were consumed by traditional grocers. Now, the once independent Web grocers make up the online channel for retail supermarkets. Likewise, e-tailers seldom think of themselves any more as the entire sales channel -- but that doesn’t mean they are disappearing altogether. Instead, they now form one part of a larger selling strategy. Not only has the Web channel become main stream, but also it has helped make a multichannel approach more effective. A customer can buy a sweater online, and then return it at the store. Or a customer can try that same sweater on in the store but buy it online. An online presence improves the shopping experience for consumers, while retailers benefit from the different points of interaction with potential customers. Finally, retail Web sites have done a better job at fulfillment, especially when dealing with tricky problems such as merchandise returns. Sites have also gotten better at delivering on promises. This year, you probably won’t see as many people complaining that the toys they bought for Christmas haven’t shown up or that orders were duplicated. Customer relationship management technology has helped sites manage customer concerns and improve relationships with customers. So don’t fall for the head-shaking this season over online retail. Business-to-consumer e-commerce is more than just here to stay -- it’s here now. The author’s attitude toward the issue is ______
A. pessimistic
B. optimistic
C. exaggerating
D. ambivalent
