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the classroom will have additional electronic tools.On the teacher's desk,the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape players.The tape machines will run pre-recorded lessons which pupils will follow by headphones.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 par-ticular 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 multi-media 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 teachers' 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.
When having lessons,the students will_________.
A.always listen to the same pre-recorded lessons together
B.usually have individual lessons according to their ability levels
C.control the multiple-control panel and magnetic tape players
D.receive face-to-face instructions from the teacher in the same classroom

[单项选择]Our surroundings are being polluted faster than ever and it seems that people cannot prevent it. Time is bringing us more people, and more people will bring us more industry, more cars, larger cities, and the growing use of man-made materials.
What can explain and settle this problem The fact is that pollution is caused by man—by his desire(欲望) for a modern way of life. We make "increasing industrialization"(工业化) our first aim. So we are often ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from the country-side into the cities, eager for the achievements of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourslves where we are going—and why It makes one think of the story about the pilot (飞行员) who told his passengers over the loudspeaker : "I’ve some good news and some bad news. The good news is that we ’re making rapid progress at 530 miles per hour. The bad news is that we are lost and don’t know where we’re going." The sad fact is that this becomes a true story when speaking of our modern society.Man cannot prevent the world from being polluted because_______.
