U. S. Blacks Hard-hit by Cancer

Death rates for cancer are falling for all Americans,but black Americans are still more
likely to die of cancer than whites,the American Cancer Society said Monday.
In a special report on cancer and blacks,the organization said blacks are usually
diagnosed with cancer later than whites,and they are more likely to die of the disease.
This could be because of unequal（不平等的）access to medical care, because blacks
are more likely to have other diseases as well,and perhaps because of differences in the
biology（生物学）of the cancer itself, the report added.
"In general,black Americans have less hope of surviving five years after diagnosis
than whites for all cancer sites and all stages of diagnosis,"the report said,
"In describing cancer statistics for black Americans,this report recognizes that many of
the differences associated with race may be caused by unfair social and economic
differences and unequal access to medical care."
The cancer society said blacks should be encouraged to get check-ups（体格检查）
earlier,when cancer is more treatable,and it said more research is needed to see if
biological differences play a role.
"The new statistics emphasize the continuing importance of wiping out these unfair
social differences through public policy and education efforts,"the organization said in a
statement.
But it also noted a drop in cancer death rates.
"Cancer death rates in both sexes for all sites combined have dropped greatly among
black Americans since 1992,as have incidence rates（发生率）,"said the report.

Cancer is more treatable if it is detected
A:in an early stage.
B:in a late stage.
C:all of a sudden.
D:together with other diseases.

Vitamins are similar because they are made of the same elements—usually carbon,hydrogen,oxygen,and sometimes nitrogen.They are different in that their elements are arranged differently,and each vitamin been（ ）one or more specific functions in the body.

A.holds
B.plays
C.performs

Communications Revolution Cyberspace,data superhighway,multi-media-for those who have seen the future,the linking of computers, television and telephones will change our lives forever.Yet for all the talk of a forthcoming technological utopia little attention has been given to the implications of these developments for the poor.As with all new high technology,while the West concerns itself.with the"how",the question of"for whom"is put aside once again. Economists are only now realizing the full extent to which the communications revolution has affected the world economy.Information technology allows the extension of trade across geographical and industrial boundaries,and transnational corporations take full advantage of it.Terms of trade,exchange and interest rates and money movements are more important than the production of goods.The electronic economy made possible by information technology allows the haves to increase their control on global markets-with destructive impact on the have-nots. For them the result is instability.Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine.As"futures"are traded on computer screens,developing countries simply have less and less control of their destinies. So what are the options for regaining control?One alternative is for developing countries to buy in the latest computers and telecommunications themselves-so-called"development communications"modernization.Yet this leads to long-term dependency and perhaps permanent constraints on developing countries'economies. Communications technology is generally exported from the U.S.,Europe or Japan;the patents,skills and ability to manufacture remain in the hands of a few industrialized countries.It is also expensive,and imported products and services must therefore be bought on credit-credit usually provided by the very countries whose companies stand to gain. Furthermore,when new technology is introduced there is often too low a level of expertise to exploit it for native development.This means that while local elites,foreign communities and subsidiaries of transnational corporations may benefit,those whose lives depend on access to the information are denied by it.

Why does the author say that the electronic economy may have a destructive impact on developing countries?
A:Because it destroys the economic balance of the poor countries.
B:Because it inhibits the industrial growth of developing countries.
C:Because it enables the developed countries to control the international market.
D:Because it violates the national boundaries of the poor countries.
