阅读下列材料：

材料一：查士丁尼统治时期，帝国政治非常腐败，贪污、贿赂成风。上自达官显贵，下到各省的大小官员，无不滥用职权，对人民进行敲诈勒索。各地驻军对群众也百般欺凌，抢劫财物，形同强盗。查士丁尼又大兴土木，在首都君士坦丁堡兴建了宏伟的宫殿和辉煌的圣索非亚教堂。长期的侵略扩张，战费消耗极大，到查士丁尼统治末期，国库空虚，民尽财穷，军队濒于瓦解，削弱了抵御外族入侵的力量。从六世纪后期起，出现强敌压境的局面，拜占廷丧失了美索不达米亚、叙利亚、巴勒斯坦和北非的大片领土。后来南部意大利和西西里岛也落入阿拉伯人之手。帝国版图大大缩小，拜占廷作为一个庞大的帝国已经走向崩溃。

[A] The take-up of EVs—which run entirely on electricity stored in rechargeable batteries—is seen as central to the plan to cut the transport sector’s carbon emissions, both here and across the European Union. It is predicted that we will be running a total of 800,000 EVs in Britain by 2020, and as a result the race to install a recharging infrastructure is well under way. Transport for London (TfL) recently announced it will have 1,300 EV charging points in London by 2013—more than the current number of petrol stations in the capital. The London mayor, Boris Johnson, is on the record as saying he wants to make the city the electric car capital of Europe.

[B] However, the power companies, sensing a good business opportunity, are now vying to sign up electric car-owning households with the offer of cheaper and faster off-peak home charging that will cut the time it takes to recharge the vehicle—freeing it to make more journeys, and making them more attractive to buyers. So far, EDF, British Gas, and most recently npower have said they will be targeting EV users with special home services as well as cheaper tariffs for recharging vehicles.

[C] What would make you consider buying an electric car They offer a green way to get around, with the chance to bypass petrol stations. And they are exempt from road tax and London’s congestion charge. Energy company npower (英国电力公司) this week revealed that 33% of UK drivers would think about buying an electric vehicle (EV) in the next five years, rising to 41% when the benefits were explained.

[D] But despite the introduction in January of a generous ￡ 5,000 government purchase grant to encourage more people to take the plunge, it’s fair to say that sales of electrically powered cars in the UK are yet to really take off. Just over 500 people took the government up on its offer in the first quarter of this year. Their high prices—typically about ￡ 25,000 after the grant—plus a lack of models by major carmakers and a shortage of charging points, have held back sales. However, the last two points are about to change.

[E] Speaking in Berlin last week, npower’s head of e-mobility, Phil Evans, told Guardian Money that the company sees EVs as a major opportunity, and as a result it is working on building an "upgradable" charging infrastructure that will develop as the cars’ power systems become more sophisticated.

[F] Potential buyers now have a choice of seven models in the UK, with 13 more on the way, while EDF Energy (英国电网), British Gas and npower have recently announced plans to start offering to install faster and cheaper charging points in customers’ homes, in a move they hope will help kick-start sales. The companies are banking on the fact that buyers of the latest, more consumer-friendly electric cars, such as the Nissan Leaf, are going to boost demand for electricity.

[G] Plans are also under way to increase the number of charging points at a variety of locations across the UK—and soon it will be possible for homeowners to upgrade their garages to allow faster, safer home charging. Until recently, most owners of plug-in-to-recharge electric cars have had to rely on the traditional three-point household plug, and wait about eight hours to fully recharge their vehicle at home.
