高三阅读理解The most eye-catching part of the government

The most eye-catching part of the government’s recent air-quality strategy is to ban sales of new petrol and diesel cars by 2040. The reason behind the government’s strategy is poor air quality, which is thought to be linked to about 40,000 premature deaths a year.
Client Earth, the campaign group leading the call for reform, has described the ban as t4not enough”. It emphasises that clean air zones and sustainable transport infrastructures both work, and can be implemented more quickly. Even so, some argue that the target is too soon. The motor industry, however, does not argue that the cars won’t be ready in time. This is unsurprising, given that Tesla already has an all-electric model, most manufacturers have at least one hybrid (混动汽车) on sale.
The voices of disagreement offer three main arguments: electric vehicles don’t reduce greenhouse gas emissions; we don’t have enough power available; and there are not enough essential materials like lithium (锂) which support most new electric vehicle battery technologies.
The first two arguments are closely related. The problem is not the absolute amount of electric vehicles on the road but when we charge them. The issue is “peak demand”. We design our electricity infrastructure systems to ensure these peaks are covered. Peak demand in the UK is between 5 pm and 7 pm in winter. This is usually when electricity is at its most “dirty”, as this is when we need almost all of our generating (发电) capacity, including the old coal plants, diesel back-up generation and gas. Without managed charging, drivers plugging the car in on return from work face using diesel engines and coal-derived power to charge vehicles. Hardly a win for air quality or climate change.
The last problem, material availability, is trickier. Lithium and the rare earth metals used in electric vehicles present problems. It’s not only a question of whether there are enough of these materials, but also their toxicity, convenience of recycling and their geopolitical availability of their supply chains. Much like the issue of peak demand, without strong policy and behavioural and technical advances, we could easily see the rise of global conflict and exploitation around the critical materials for electric mobility.
While a ban on petrol and diesel car sales in 2040 is easily achievable, what really matters is how well the above issues are dealt with. Electric cars do nothing for traffic jams. Their power source needs careful management, and their supply chains may be no less problematic than those of petrochemical fuels. Conversely, they can reduce air pollution and help meet climate change commitments. Like many technical solutions they need strong regulation around them. We should improve our dialogue on electric mobility, seeking clear government policy on energy market integration and strong standards on material sustainability.
61. The underlined word “implemented” in Paragraph 2 is closest in meaning to ______.
A. abolished  B. conducted   C. replaced    D. updated
62. What can we infer from the calm reaction from the motor industry?
A. All manufacturers have already had at least one electric car on sale.
B. The motor industry plans to focus on sustainable transport infrastructures.
C. The motor industry has already adjusted its products to reduce air pollution.
D. The recent air-quality strategy is unrealistic and impossible to follow.
63. According to the author, the best time to get your car charged is ______.
A. when “peak demand” ends   B. directly after returning from work
C. when other people do   D. right before moving to work
64. Which of the following best expresses the meaning of the underlined part in Paragraph 6?
A. Careful management is likely to address the problems with both types of cars.
B. It seems that currently petrol and diesel cars are more problematic than electric cars.
C. Petrol and diesel cars and electric vehicles seem to face the same problems nowadays.
D. Currently electric vehicles seem to face more problems than petrol and diesel cars do.

 


答案 61.B  62. C  63. A  64.D
