Yet for all the talk of a forthcoming technological utopia little attention has been given to the implications of these developments for the poor. As with all new high technology, while the West concerns itself with the "how", the question of "for whom" is put aside once again. Economists are only now realizing the full extent to which the communications revolution has affected the world economy. Information technology allows the extension of trade across geographical and industrial boundaries, and transnational corporations take full advantage of it. Terms of trade, exchange and interest rates and money movements are more important that the production of goods. The electronic economy made possible by information technology allows the haves to increase their control on global markets—with destructive impact on the have-nots. For them the result is instability. Developing countries which rely on the production of a small range of goods for export are made to feel like small parts in the international economic machine. As "futures" are traded on computer screens, developing countries simply have less and less control of their destinies. So what are the options for regaining control? One alternative is for developing countries to buy in the latest computers and telecommunications themselves—so-called "development communications" modernization. Yet this leads to long-term dependency and perhaps permanent constraints on developing countries' economies. Communications technology is generally exported from the U. S., Europe or Japan; the patents, skills and ability to manufacture remain in the hands of a few industrialized countries. It is also expensive, and imported products and services must therefore be bought on credit—credit usually provided by the very countries whose companies stand to gain. Furthermore, when new technology is introduced there is often too low a level of expertise to exploit it for native development. This means that while local elites, foreign communities and subsidiaries of transnational corporations may benefit, those whose lives depend on access to the information are denied it.

单选题 Adaptation of Living Things Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their {{B}}environments{{/B}}. Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of plants have. Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near. Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its own environment, as do warm-blooded mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions.

单选题Status of Teachers in America At present, in many American cities especially, many teachers in the public schools say they are underpaid. They point to jobs such as secretary or truck driver, which often pay more to start than that of the teacher. In many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher who has taught for several year. Teaching has never been a profession that attracted people interested in high salaries. It is by history a profession that has provided rewards in addition to money, the satisfaction of sharing knowledge, of influencing others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many, than there are rewards. Unruly students, who would have chosen teaching as their life career in the past, are going into other fields. Another reason for this change in teacher candidates is the changing status of women in the United States. Until the late 1960s and 1970s, one of the most popular choices for women was teaching. But as other professions, such as law and medicine opened up to women, women stopped pouring into teacher training programs. Thus, a major pool of excellent candidates for the teaching profession dwindled (减少). Bit by bit government officials and others realized that the status of the teacher had suffered. They talked about change. But change in a vast society like the United States is not easy. People's attitudes have formed over many years, and sometimes change takes many years.

It's about being genuinely interested and having regular conversations about what they're learning," says J. Gary Knowles, a professor at the Ontario Institute for Studies in Education, part of the University of Toronto. Rozon has a slew of suggestions for how to get more involved. "Get to know the teacher. Discuss ways to tailor the assignments to your child's learning style. Spend time in the classroom. Ask for outlines of unit studies so you can find supplementary materials at the library or through videos. Read your child's textbooks: If you work a few pages ahead, you'll be able to help them with problems they encounter." Reading is another must, says Rozon. "Even after your children can read themselves, hearing somebody else read aloud is important. We nearly always have a book on the go; we read for at least a half hour before bedtime." The more engaged a parent is, the more the child benefits, adds Bruce Arai. "The evidence is clear: Parental involvement is one of the most important factors in school success." Arai cites the National Longitudinal Survey of Children and Youth, sponsored by Human Resources Development Canada (HRDC), which is measuring all aspects of child development. "The hours children spend in class are but one element of their education," states HRDC, which says parental support, along with teacher support and a positive attitude towards school, all contribute to academic success. "I see every moment of every day as a learning experience," says Goforth. "The most satisfying part of it is seeing the love of learning continued. I'm not squelching my children's desire to learn by insisting they learn. They learn because they want to." Adds Jeanne Lambert, mother of Carey Graham: "Make the time, take the time, guide, lead, and encourage. If nothing else, your children learn you care, and that's the most important lesson you can give them."
