It may turn out that the "digital divide"--one of the most fashionable political slogans of recent years--is largely fiction. As you will recall, the argument went well beyond the unsurprising notion that the rich would own more computers than the poor. The disturbing part of the theory was that society was dividing itself into groups of technology "haves" and "have-nots" and that this segregation would, in turn, worsen already large economic inequalities. It is this argument that is either untrue or wildly exaggerated.
We should always have been suspicious. After all, computers have spread quickly because they have become cheaper to buy and easier to use. Falling prices and skill requirements suggest that the digital divide would spontaneously shrink--and so it has.
Now, a new study further discredits the digital divide. The study, by economist David Card of the University of California, Berkeley, challenges the notion that computers
A. to advocate the elimination of poverty
B. to justify the influence of the digital divide
C. to democratize computer access today
D. to expose the myths of the digital divide

[单项选择]Terrorism has become so widespread that it is now impossible to dismiss it as the action of a few crazy people. In fact, terrorism--the use of violence by small groups of people to accomplish political alms they feel unable to bring about by peaceful, legitimate means--has sociological roots.
Terrorism most often stems from the situation of people who consider themselves a national group but who feel that no state, no legitimate and widely recognized autonomous government, represents them. Since all the inhabitable territory of the world is divided into states, which are the main organizational units through which people can exercise political power, people without a state to represent them feel completely powerless and cut off from the world order. To have independence--and even a recognized identity--as a people, those individuals feel that, too, must have a sovereign state government. Thus terrorism is frequently a tactic of people who find themselves or feel themselves to b
A. they regard themselves as independent people
B. they feel that no widely recognized independent government represent them
C. they are cited by those people with a sovereign state government
D. they do not have means to exercise political power
