单选题Recently I stood in front of my class, observing an all-too-familiar scene. Most of my students were secretly—or so they thought—looking at their smart phones under their desks. As I called their attention, students" heads slowly lifted, their eyes reluctantly glancing forward. I then cheerfully explained that their next project would practice a skill they all desperately needed: holding a conversation. Several students looked confused. Others moved uneasily in their seats, waiting for me to stop watching the class so they could return to their phones. Even with plenty of practice, most kids were unable to converse effectively. They looked down at their hands. Some even reached for their phone—the last thing they should be doing. As I watched my class struggle, I came to realize that conversational competence might be the single-most overlooked skill we fail to teach students. Kids spend hours each day engaging with ideas and one another through screens—but rarely do they have an opportunity to truly practice their interpersonal communication skills. Admittedly, teenage awkwardness and nerves play a role in difficult conversations. But students, reliance on screens for communication is affecting their engagement in real-time talk. It might sound like a funny question, but we need to ask ourselves: Is there any 21st century skill more important than being able to hold a confident, coherent (连贯的) conversation? When students apply for colleges and jobs, they won"t conduct interviews through their smart phones. When they negotiate pay raises and discuss projects with employers, they should demonstrate a thoughtful presence and the ability to think on their feet. But in our rash to meet 21st-century demands, we aren"t asking students to think and communicate in real time. Online discussion boards and Twitter are useful tools for exchanging ideas. But they often encourage a "read, reflect, forget about it" response that doesn"t truly engage students in extended critical thinking or conversation. As Sherry Turkle writes, "We are tempted to think that our little "sips" of online connection add up to a big gulp (大口) of real conversation. But they don"t."

单选题Most of the plans and programs for diminishing crime by means of comprehensive community organization have made prevention their major purpose. However, the underlying concepts on which such programs are based suffer from inconsistency (不一致，矛盾) and confusion. It would be inaccurate to speak as if concise, clear, and explicit models for crime prevention existed especially since writing and discussion on the subject often have been more ideological than scientific. One conception heavily weighted with ideology is the argument that crime can be prevented by massive or total programs of social and economic improvement directed at the root causes of crime in society as a whole. The assumption is that eliminating harmful social conditions such as poverty, malnutrition, disease, poor housing, family disorganization, unemployment, and racial discrimination will make crime disappear. Crime is traced to a pathological (病态的) or broken social structure, and only a thorough renovation or replacement of that structure will usher in a crimeless society. This conception has revolutionary implications going back to older socialist beliefs that poverty or class exploitation causes crime. Among the methods it advocates to solve social problems is the activation of some forms of popular democracy. Another form of social improvement more sophisticated in conception has been loosely designated as "opportunity theory ". This conception holds that crime results from psychic pressures in individuals who are culturally indoctrinated (灌输) with achievement values and yet have no opportunity for upward mobility because of their unfortunate position in a rigid social structure. Those so disadvantaged are primarily youths in the lower socio-economic strata. Amelioration (改善) inspired by opportunity theory employs vaguely martial imagery: it speaks of the "mobilization" of community resources to make "war" on poverty. Broad-scale programs of social and cultural improvement may be desirable or necessary at times, but since they fail to explain why some poverty-stricken youths turn to crime while others do not, their efficacy (功效) in eradicating and preventing crime is questionable at best. So far only one country, the Soviet Union, has conducted a large-scale revolutionary experiment in social improvement, and the results have not been affirmative: Soviet authorities are still plagued by juvenile crime. This experiment suggests that social improvement is too scattered in its impact to be an effective means of crime prevention.
