[单项选择] {{B}}Passage One{{/B}}
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,
A. explore the sociological roots of terrorism and enhance the international cooperation to fight against it
B. defend terrorism as a heroic deeds
C. praise terrorism for its heroic deeds
D. demonstrate the damages done by terrorism
