单选题Migration is usually defined as "permanent or semi-permanent change of residence". However, our concern is with movement between nations, not with internal migration within nations, although such movements often exceed international movements in volume. Today, the motives of people who move short distances are very similar to those of international migrants. Students of human migration speak of "push" and "pull" factors, which influence an individual's decision to move from one place to another. Push factors are associated with the place of origin. A push factor can be as simple and mild a matter as difficulty in finding a suitable job, or as traumatic as war, or severe famine. Obviously, refugees who leave their homes with guns pointed at their heads are motivated almost entirely by push factors (although pull factors do influence their choice of destination). Pull factors are those associated with the place of destination. Most often these are economic, such as better job opportunities or the availability of good land to farm. In general, pull factors add up to an apparently better chance for a good life and material well-being than is offered by the place of origin. When there is a choice between several attractive potential destinations, the deciding factor might be a non-economic consideration such as the presence of relatives, friends, or at least fellow countrymen already established in the new place who are willing to help the newcomers settle in. Besides push and pull factors, there are what the sociologists call "intervening obstacles." Even if push and (or) pull factors are very strong they still may be outweighed by intervening obstacles, such as the distance of the move, the trouble and cost of moving, the difficulty of entering the new country, and the problems likely to be encountered on arrival. The decision to move is also influenced by "personal factors" of the potential migrant. The prospect of packing up everything and moving to a new and perhaps very strange environment may appear interesting and challenging to an unmarried young man and appallingly difficult to a slightly older man with a wife and small kids. Similarly, the need to learn a new language and customs may excite one person and frighten another. Regardless of why people move, migration of large numbers of people causes conflict. The United States and other western countries have experienced adjustment problems with each new wave of immigrants. It has usually taken several decades for each group to be accepted into the mainstream of society in the host country.

单选题{{B}}练习九{{/B}} A new era is upon us. Call it what you will: the service economy, the information age, the knowledge society. It is all translated to a fundamental change in the way we work. Already we've partly been there. The percentage of people who earn their living by making things has fallen dramatically in the Western World. Today the majority of jobs in America, Europe and Japan (two thirds or more in many or these countries) are in the service industry, and the number is on the rise. More women are in the work force than ever before. There are more part-time jobs. More people are self-employed. But the breadth of the economic transformation can't be measured by numbers alone, because it is also giving rise to a radical new way of thinking about the nature of work itself. Long-held notions about jobs and careers, the skills needed to succeed, even the relation between individuals and employers—all these are being changed. We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip (集成电路), would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow's achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more vital, and the people who possess it, whether .they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write The ability to solve problems by applying information instead of performing routine tasks will be above all else. If you cast your mind ahead 10 years, information services will be predominant It will be the way you do your job.

单选题{{B}}Text 3{{/B}} One of the saddest things about the period in which we live is the growing estrangement(疏远) between America and Europe. This may be a surprising discovery to those who are over impressed by the speed with which turbojets can hop from New York to Paris. But to anyone who is aware of what America once meant to English libertarian poets and philosophers, to the young Ibsen bitterly excoriating (痛斥) European royalty for the murder of Lincoln, to Italian novelists and poets translating the nineteenth century American classics as a demonstration against Fascism, there is something particularly disquieting in the way that the European Left, historically " pro-American" because it identified America with expansive democracy, now punishes America with Europe's lack of hope in the future. Although America has obviously not fulfilled the visionary hope entertained for it in the romantic heyday, Americans have, until recently, thought of themselves as an idea, a "proposition" (in Lincoln's word) set up for the enlightenment and the improvement of mankind. Officially, we live by our original principles; we insist on this boastfully and even inhumanly. And it is precisely this steadfastness to principle that irks(使苦恼，使厌烦) Europeans who under so many pressures have had to shift and to change, to compromise and to retreat. Historically, the obstinacy of America's faith in "principles" has been staggering--the sacrament(神圣) of the Constitution, the legacy of the Founding Fathers, the moral rightness of all our policies, the invincibility of our faith in the equality and perfectibility of man. From the European point of view, there is something impossibly romantic, visionary, and finally outrageous about an attachment to political formulas that arose even before a European revolutionary democracy was born of the French Revolution, and that have survived all the socialist utopias and internationals. Americans honestly insist on the equality of men even when they deny this equality in practice; they hold fast to romantic doctrines of perfectibility even when such doctrines contradict their actual or their formal faith whether it be as scientists or as orthodox Christians. It is a fact that while Americans as a people are notoriously empirical, pragmatic, and unintellectual, they live their lives against a background of unalterable national shibboleths (陈旧的语句). The same abundance of theory that allowed Walt Whitman to fill out his poetry with philosophical road signs of American optimism allows a president to make pious references to God. As an American tradition--references which, despite their somewhat mechanical quality, are not only sincere but which, to most Americans, express the reality of America.

单选题 The component of the healthy personality that is the first to develop is the sense of the trust. The crucial time for its emergence is the first year of life. As with other personality components, the sense of trust is not something that develops independent of other manifestations of growth. It is not that infants learn how to use their bodies for purposeful movement, learn to recognize people and objects around them, and also develop a sense of trust. Rather, the concept "sense of trust" is a shortcut expression intended to convey the characteristic flavor of all the child's satisfying experiences at this early age. Or, to say it another way, this psychological formulation serves to condense, summarize, and synthesize the most important underlying changes, which give meaning to the infant's concrete and diversified experience. Trust can exist only in relation to something. Consequently, a sense of trust cannot develop until infants are old enough to be aware of objects and persons and to have some feeling that they are separate individuals. At about 3 months of age, babies are likely to smile, if somebody comes close and talks to them. This shows that they are aware of the approach of the other person, that pleasurable sensations are aroused. If, however, the person moves too quickly or speaks too sharply, these babies may look and cry. They will not "trust" the unusual situation but will have a feeling of uneasiness, of mistrust, instead. Experience connected with feeding are a prime source for the development of trust. At around 4 months of age, a hungry baby will grow quiet and show signs of pleasure at the sound of an approaching footstep, anticipating (trusting) that he or she will be held and fed. This repeated experience of being hungry, seeing food, receiving food, and feeling relieved and comforted assures the baby that the world is a dependable place. Later experiences, starting at around 5 months of age, add another dimension to the sense of trust. Though endless repetitions of attempts to grasp for and hold objects, most babies are finally successful in controlling and adapting their movements in such a way as to reach their goal. Through these and other feats of muscular coordination, babies are gradually able to trust their own bodies to do their bidding. Studies of mentally-ill individuals and observations of infants who have been grossly deprived of affection suggest that trust is an early-formed and important element in the healthy personality. Psychiatrists find again and again that the most serious illnesses occur in patients who have been sorely neglected or abused or otherwise deprived of love in infancy. Similarly, it is a common finding of psychological and social investigators that individuals diagnosed as "psychopathic personalities" were so unloved in infancy that they have no reason to trust the human race and therefore, no feeling of responsibility toward their fellow human beings.
