The prototype, fifty-passenger single-deck vehicle, is to go in operation in Manchester shortly, and discussions with the Department of the Environment are expected to lead to a further batch of twenty going into regular passenger service in Manchester within two year and possibly in other cities, including London.
Unlike the small government-sponsored battery bus now undergoing trials in provincial cities, whose low speed and range effectively limits it to city-center operation, the new Silent Rider, with a range 40 miles between charges and a speed of 40 m. p. h. , will take its place with diesel buses for normal urban and sub urban services.
Its capital cost is higher (about 20,000 pounds compared with 1500 pounds) but lower maintenance and fuel costs bring it down to fully competitive cost with the diesel bus over thirteen year without taking into account the environmental benefits. The Chloride battery group--which is developing it in partnership with SELN (South-East Lancashire and North-East Cheshire Passenger Transport Authority) is confident of a market potential of 400 vehicles a year by 1980.
The prototype weighs 16 tons, of which the batteries and passengers account for each. It has a single set of batteries, which take three and a half hours to recharge, against the normal eight hours of passenger traffic.
A larger , Mark II version is being designed with two sets of batteries which can be charged in under a minute. That will allow low-cost night charging and greater operational flexibility.
What had been the main factor preventing the development of battery buses？

听力原文： International donors meeting in the Ethiopian capital Addis Ababa have been asked to provide vital support for the African Union (AU) peacekeeping mission in the Sudanese region of Darfur. The African Union has just over two and a half thousand troops in Darfur monitoring the security situation there. It has agreed to increase their number fourfold. But African countries lack the resources. The United Nations Secretary-General Kofi Annan is opening the Addis Ababa meeting at which donors from the United Nations, the European Union and NATO will examine request for help. The NATO Secretary-General Jaap de Hoop Scheffer told the BBC his organization was ready to help the African Union.
"As a NATO Secretary-General, and I'm as much shocked and appalled and so are the NATO allies by what's happening in.. in... in Darfur. Indeed we should be able to do much more than we do at the moment. But given the present situation, I'm here, on behalf of NATO to see what NATO can assist the African Union."
The donors come from the following international groups EXCEPT ______.
You don't have to look very far to find out why the official reactions to medical findings have been so lukewarm. The answer is simply money. Tobacco is a wonderful commodity to tax. It's almost like a tax on our daily bread. In tax revenue alone, the government of Britain collects enough from smokers to pay for its entire educational facilities. So while the authorities point out ever so discreetly that smoking may, conceivable, be harmful, it doesn't do to shout too loudly about it.
This is surely the most short-sighted policy you could imagine. While money is eagerly collected in vast sums with one hand, it is paid out in increasingly vaster sums with the other. Enormous amounts are spent on cancer research and on efforts to cure people suffering from the disease. Countless valuable lives are lost. In the long run, there is no doubt that everybody would be much better-off if smoking were banned altogether.
Of course, we are not ready for such a drastic action. But if the governments of the world were honestly concerned about the welfare of their peoples, you'd think they'd conduct aggressive anti-smoking campaigns. Far from it! The tobacco industry is allowed to spend staggering sums on advertising. Its advertising is as insidious as it is dishonest. We are never shown pictures of real smokers coughing up their lungs early in the morning. That would never do. The advertisement always depict virile, clean-shaven young men. They suggest it is manly to smoke, even positively healthy! Smoking is associated with the great open-air life, with beautiful girls, true love and togetherness. What utter nonsense!
For a start, governments could begin by banning all cigarette and tobacco advertising and should then conduct anti-smoking advertising campaigns of their own. Smoking should be banned in all public places like theatres, cinemas and restaurants. Great efforts should be made to inform. young people especially of the dire consequences of taking up the habit. A horrific warning—say, a picture of a death's head—should be included in every packet of cigarettes that is sold. As individuals, we are certainly weak, but if governments acted honestly and courageously, they could protect us from ourselves.
Why do a few governments take timid measures toward smoking？
A．Be annoyed.B．Be protestatory.C．Be tit for tat.D．Be tactfully about anything misunder
