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 On the teacher's desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape player.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.
In paragraph one, what does "the school of tomorrow" mean？
A．The school with a central building.
B．The school with four or five master studios.
C．The school with television.
D．The school with televised lessons and electronic teaching tools.
第8题

A．only a single classroom in the school

听力原文： Electronic Commerce or e-commerce refers to the exchange of goods and services by means of the Internet or other computer networks. E-commerce follows the same basic principles as traditional commerce-that is, buyers and sellers come together to exchange goods for money. But rather than conducting business in the traditional way-in mores or through mail order catalogs and telephone operators-in e-commerce buyers and sellers do business over networked computers.
E-commerce offers buyers convenience. They can visit the World Wide Web sites of multiple sellers 24 hours a day and seven days a week to compare prices and make purchases, without having to leave their hones or offices. In some eases, consumers can immediately obtain a product or service, such as an electronic book, a music file, or computer software, by downloading it over the Internet.
For sellers, e-commerce offers a way to cut costs and' expand their markets. They do not need to build staff, or maintain a store or print and distribute mall order catalogs. Because they sell over the global Internet, sellers have the potential to market their products or services globally and are not limited by the physical location of a store.
E-commerce also has some disadvantages, however. Consumers are reluctant to buy some products online. Online furniture businesses, for example, have failed for the most part because customers want to test the comfort of an expensive item such as a sofa before they purchase it. Many people also consider shopping a social experience. For instance, they may enjoy going to a store or a shopping mall with friends or family. Consumers also need to be reassured that credit card transactions are secure and that their privacy is being respected.

A．Do business in stores.

D．Do business through mall order catalogs and telephone operators.

听力原文： By the end of the 1980s, U2 had established itself not only as one of the world's most popular bands but also as one of the most innovative. The members are Bono, the Edge, Adam Clayton and Larry Mullen Jr. The band members were attending a Dublin secondary school when they began rehearsing in spite of their lack of technical expertise. The band's early records were characterized by an intense spirituality, and they commented on social and political issues, with compassion and tenderness.
The group became renowned for its inspirational live performances before it made much of an impact on the pop charts. But with the multimillion-selling success of The Joshua Tree album and the number one hits With or Without You and I Still Haven't Found What I'm Looking For, U2 became pop stars.
On Rattle and Hum, the bend explored American roots music—blues, country, and folk—with typical earnestness, but were ridiculed by some critics who found the project shallow.
U2 reinvented itself for the new decade, reemerging in 1991 with the album Achtung Baby and a sound heavily influenced by European experimental, electronic, and disco music. However, despite the flashy exterior, the band's lyrics remained obsessed with matters of the soul. In 2000, U2 released the aptly entitled (All That You Can't Leave Behind), which combined the elements of the band's earlier music.
(23)
A．Intense spirituality.
B．Inspirational live performance.
C．Innovativeness.
D．Influenced by European disco music.
