问题 "The Digital Divide"
   The Challenge of Technology and Equity
   Information technology is influencing the way many of us live and work today. We use the Internet to look and apply for jobs, shop, conduct research, make airline reservations, and explore areas of interest. We use e-mail and the Internet to communicate instantaneously with friends and business associates around the world. Computers are commonplace in homes and the workplace.
   Although the number of Internet users is growing exponentially each year, most of the world’s population does not have access to computers or the Internet. Only 6 percent of the population in developing countries are connected to telephones. Although more than 94 percent of U.S. households have a telephone, only 56 percent have personal computers at home and 50 percent have Internet access. The lack of what most of us would consider a basic communications necessity—the telephone—does not occur just in developing nations. On some Native American reservations only 60 percent of the residents have a telephone. The move to wireless connections may eliminate the need for telephone lines, but it does not remove the barrier to equipment costs.
   Who has Internet access? The digital divide between the populations who have access to the Internet and information technology tools and those who don’t is based on income, race, education, household type, and geographic location, but the gap between groups is narrowing. Eighty-five percent of households with an income over $75,000 have Internet access, compared with less than 20 percent of the households with incomes under $15,000. Over 80 percent of college graduates use the Internet as compared with 40 percent of high school completers and 13 percent of high school dropouts. Seventy-two percent of households with two parents have Internet access; 40 percent of female, single-parent households do. Differences are also found among households and families from different racial and ethnic groups. Fifty-five percent of white households, 31 percent of black households, 32 percent of Latino households, 68 percent of Asian or Pacific Islander households, and 39 percent of American Indian, Eskimo, or Aleut households have access to the Internet. The number of Internet users who are children under nine years old and persons over fifty has more than tripled since 1997. Households in inner cities are less likely to have computers and Internet access than those in urban and rural areas, but the differences are no more than 6 percent.
   Another problem that exacerbates these disparities is that African-Americans, Latinos, and Native Americans hold few of the jobs in information technology. Women hold about 20 percent of these jobs and are receiving fewer than 30 percent of the bachelor’s degrees in computer and information science. The result is that women and members of the most oppressed ethnic groups are not eligible for the jobs with the highest salaries at graduation. Baccalaureate candidates with degrees in computer science were offered the highest salaries of all new college graduates.
   Do similar disparities exist in schools? A    Ninety-eight percent of all schools in the country are wired with at least one Internet connection. B    The number of classrooms with Internet connections differs by the income level of students. Using the percentage of students who are eligible for free lunches at a school to determine income level, we see that a higher percentage of the schools with more affluent students have wired classrooms than those with high concentrations of low-income students.   C
   Access to computers and the Internet will be important in reducing disparities between groups. D    It will require greater equality across diverse groups whose members develop knowledge and skills in computer and information technologies. The field today is overrepresented by white males. If computers and the Internet are to be used to promote equality, they will have to become accessible to schools that cannot currently afford the equipment which needs to be updated regularly every three years or so. However, access alone is not enough. Students will have to be interacting with the technology in authentic settings. As technology becomes a tool for learning in almost all courses taken by students, it will be seen as a means to an end rather than an end in itself. If it is used in culturally relevant ways, all students can benefit from its power.
The word concentrations in the passage is closest in meaning to
选项 A、protections
B、numbers
C、confidence
D、support
答案B
解析 In this passage, numbers is a synonym for "concentrations." Context comes from the references in previous sentences to "percentage" and "number."
