Ford Abandons Electric Vehicles
The Ford motor company's abandonment of electric cars effectively signals the end of the road for the technology，analysts say.
General Motors.and Honda'ceased production of battery.powered cars in 1 999， to focus on fuel cell and hybrid electric gasoline engines， which are more attractive to the consumer.Ford has now announced it will do the same.
Three years ago.the company introduced the Think City two—seater car and a golf cart called the THINK， or Think Neighbor.It hoped to sell 5，000 cars each year and 10，000 carts.But a lack of demand means only about l，000 of the cars have been produced，and less than 1.700 carts have been sold so far in 2002.
“The bottom line is we don't believe that this is the future of environment transport for the mass market.”Tim Holmes of Ford Europe said on Friday.“We feel we have given electric our best shot”
The Think City has a range of only about 53 miles and up to a six-hour battery recharge time.General Motors'EVI electric vehicle also had a limited range.of about 100 miles.
The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives.An electric Toyot~RAV4 EV vehicle costs over$42，000 in the US， compared with just $17，000 for the petrol version.Toyota and Nissan…are now the only major automanufacturers to produce electric vehicles.
“There is a feeling that battery electric has been given its chance.Ford now has to move on with its hybrid program”，and that is what we will be judging them on，“Roger Higman，a senior transport campaigner at UK Friends of the Earth，told the Environment News Service.
Hybrid cars introduced by Toyota and Honda in the past few years have sold well.Hybrid engines Offer Greater mileage than petrol—only engines ， and the batteries recharge themselves. Ford says it thinks such vehicles will help it meet planned new guidelines “on vehicle emissions” in the U.S.
However， it is not yet clear exactly what those guidelines will permit.In June，General Motors and Daimler Chrysler won a court injunction，delaying by two years Californian legislation requiring car—makers to offer 100，000 zero-emission and other low—emission vehicles in the state by 2003.Car manufacturers hope the legislation will be rewritten to allow for more low——emission，rather than zero—emission，vehicles.

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 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 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.

A） the school of tomorrow.
B） classrooms.
C） big buildings.
D） master studios.
2. Which of the following statement about the function of the teacher in the teaching process is true？
A） The teacher will not need to be involved.
B） The teacher will still have to play an important role.
