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 1999, 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 1,000 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 55 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 Toyota 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 auto manufacturers 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 US.
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.
What have the Ford motor company, General Motor's and Honda done concerning electric cars？
Students' Evaluation of Classroom Teaching
For the past two years, I have been working on students' evaluation of classroom teaching. I have kept a record of informal conversations(51)some 300 students from at least twenty--one colleges and universities. The students were generally(52)and direct in their comments(53)how course work could be better(54). Most of their remarks were kindly taken --with tolerance rather than bitterness--and frequently were softened by the(55) that the students were speaking(56)some, not all, instructors. Nevertheless,(57)the following suggestions and comments indicate, students feel dissatisfied with things--as--they --are in the classroom.
Professors should be(58)from reading lecture notes. "It makes their(59)monotonous(单调的)."
If they are going to read, why not(60)out copies of the lecture？ Then we shouldn't need to go to class. Professors should(61)repeating in lectures material that is in the textbook."(62)we've read the material, we want to(63)it or hear it elaborated on, not repeated." "A lot of students hate to buy a(64)text that the professor has written(65)to have his lectures repeat it. '
