    According to the passage, distance learning . A. is still expensive for ordinary students B. will take place mainly in classrooms. C. will play a more important role in students’ learning. D. will still affect badly on the low-graded students D More surprising, perhaps, than the present difficulties of traditional marriage is the fact that marriage itself is alive and thriving. As Skolnick notes, Americans are a marrying people: relative to Europeans, more of us marry and we marry at a younger age. Moreover, after a drop in the early 1915s, the rate of marriage in the United States is now increasing. Even the divorce rate needs to be taken in this remarriage context: some 30 percent of divorced individuals remarry. Thus, marriage remains by far the preferred way of life for the vast majority of people in our society. What has changed more than marriage is the nuclear family. Twenty five years ago, the typical American family was made up of a husband, a wife, and two or three children. Now, there are many marriages in which couples have decided not to have any children. And there are many marriages where at least some of the children are from the wife’s former marriage, or the husband’s, or both. Sometimes these children spend all of their time with one parent from the former marriage; sometimes they are shared between the two former spouses . Thus, one can find every type of family arrangement. There are marriages without children; marriages with children from only the present marriage; marriages with “fulltime children from both the present and former marriages; marriages with “fulltime children from the present marriage and “part-time children from former marriages. There are stepfathers, stepmothers, half brother’s, and half sisters. It is not all that unusual for a child to have four parents and eight grandparents! These are great changes from the traditional nuclear family. But even so, even in the midst of all this, there remains one constant: Most Americans spend most of their adult lives married. 【查看更多】

     

    题目列表(包括答案和解析)

    The new model is the highly interactive（互动的）learning model. We could also call it the conversational model, or the tutorial model. It is computer based, with the interaction between the student, or a small group of students, and learning programs are like the conversation between a student and a skilled tutor. Distance learning will be the main delivery method.

    Student interaction with the learning material on the computer will use the student's natural language; it will seem like a conversation between a student and a human tutor. This is the key point of highly interactive, or conversational, learning units. Programs will ask questions in the student’s native language, and respond reasonably to free-form student input. Multiple choice and pointing will seldom be used; they often do not allow individualization (个体化) of education.

    An important aspect of this model is that the computer will frequently store information about the student, about problems and about how far individual students have progressed. These records will be used often within the programs. Thus when a student returns to the learning activity, the computer knows about that student and knows where to begin the new part.

    Global education is critical for the future, to get rid of poverty, corruption (腐败), violence and war, to solve major problems such as the lack of drinkable water, and to insure a happy life for all. Education should no longer be limited to the wealthy of the world, but should be available to everyone.

    In the new distance learning environment learning can take place in markets, libraries, public buildings, learning centers, and the home. Gradually schools and universities will play a smaller role in learning, both because better learning can be delivered through such highly interactive material, and because such learning will be less costly for the individual student. Motivation (动机)is particularly important in a mastery-based distance learning, as the usual threats of traditional classrooms such as that of low grades are no longer possible.

    Voice input will probably be the mode(模式) for this interaction. The new voice input systems from several companies are useful, cheap, and speaker independent in highly interactive learning. Keyboards may not be needed. Speech is a natural way for humans to communicate.

    Students will work in small peer groups, about four. Other contacts with people, learning circles, will be possible, directly or electronically.
