[单项选择]The fact that most Americans live in urban areas does not mean that they reside in the center of large cities. In fact, more Americans live in the suburbs of large metropolitan areas than in the cities themselves.
The Bureau of the Census regards any area with more than 2,500 people as an urban area, and does not consider boundaries of cities and suburbs.
According to the Bureau, the political boundaries are less significant than the social and economic relationships and the transportation and communication systems that integrate a locale. The term used by the Bureau for an integrated metropolis is an MSA, which stands for Metro politan Statistical Area. In general, an MSA is any area that contains a city and its surrounding suburbs and has a total population of 50,000 or more.
At the present time, the Bureau reports more than 280 MSAs, which together account for 75 percent of the US population. In addition, the Bureau recognizes 18 megapolises, that is, continuous adjac

[单项选择]What our society suffers from most today is the absence of consensus about what it and life in it ought to be; such consensus cannot be gained from society’s present stage, or from fantasies about what it ought to be. For that the present is too close and too diversified, and the future too uncertain, to make believable claims about it. A consensus in the present hence can be achieved only through a shared understanding of the past, as Homer’s epics informed those who lived centuries later what it meant to be Greek, and by what images and ideals they were to live their lives and organize their societies.
Most societies derive consensus from a long history, a language all their own, a common religion, common ancestry. The myths by which they live are based on all of these. But the United States is a country of immigrants, coming from a great variety of nations. Lately, it has been emphasized that an asocial, narcissistic personality has become characteristic of Americans, an

B. worry and suffering.
C. shared beliefs.

[单项选择]
Some people argue that self-plagiarism(自我剽窃) is impossible by definition because plagiarism is theft and people cannot steal from their own work. But, this is not correct in law. And there are circumstances, such as insurance fraud(保险欺诈), etc, when it is possible to steal from oneself.
Self-plagiarism, however, must be carefully distinguished from the recycling of one’s work that to a greater or lesser extent everyone legally does. Self-plagiarism in academic (学术的) publications is a gray area. However, many universities indirectly recognize the practice as deceptive. They publish rules preventing students from handing in basically the same essay for credit in different courses. There are also rules against someone handing in the same graduate thesis to different universities. Among established academics, self-plagiarism is a problem. It means basically the same article or book is handed in on more than one occasion for salary raising or promotion.
