Electronic Teaching The potential of closed-circuit television and other new electronic teaching tools is so great that it is fascinating to visualize "the school of tomorrow" Televised lessons will originate from a central building having perhaps four or five master studios. The lessons will be carried into classrooms all over a city, or even an entire country. After a televised lesson has been given, the classroom teacher will take over for the all-important "follow-up" period. The students will ask any troublesome questions, and difficult points will be cleared up through discussion. The teacher in the classroom will have additional electronic tools. On the teacher’s desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape player. The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to the students’ levels of ability. For instance, while the class as a whole studies history, each student will receive an individual history lesson, directed to his particular level of ability. Should question arise, the students will be able to talk directly to the teacher on individual "intercoms" without disturbing the rest of the class. In this way, the teacher will be able to conduct as many as three classes at the same time. With the rapid development of computer science, students will be aided with specially prepared multimedia software to study their subjects better. Homework will possibly be assigned and handed in via electronic mail system. Students can even take examinations on their computer linked with the teacher’s and get the score instantly. They will get certificates or diplomas if they pass all the required examinations. Experts believe that this type of education will be very popular in the years ahead. What kind of lessons will the students have

It’s in the CardsIn recent years, more and more people have been paying for things with credit cards. There are now 565 million credit cards worldwide, but it doesn’t stop there. Debit cards (电子记账卡) are being issued by banks, and store cards are being offered by many department stores. Bills and coins are gradually being replaced by "plastic money." In many countries, phone cards have been introduced for people to use in pay phones. In addition, cards made of paper are being replaced by plastic ones by many organizations and clubs. For example, if you belong to a sports club, your membership card may well be made of plastic.How safe is the plastic used to make these cards, though Until now, most cards have been made from a plastic called PVC. While PVC is being produced, harmful chemicals are released into the atmosphere. One of the most dangerous chemicals that is released is dioxin, which is known to cause cancer in humans. A further problem is that, when a PVC card is thrown away, it is not biodegradable; this means that it does not "break down" and cannot be recycled. Obviously, recycling reduces pollution of the environment.The executive director of the environmental organization and charity Greenpeace, Peter Melchett, says, "If there is a solution to this-and an alternative then it would be madness not to use it." Greenpeace has found a solution and an alternative. Their new credit card is made entirely from a biodegradable plastic that uses plants. The card breaks down in around three months in soil; in this way, it is recycled. In contrast, a PVC card lasts for centuries. Greenpeace hopes that many organizations will soon follow their example and issue cards that do not threaten the public health. Greenpeace cards are widely used in many organizations now.()
