A

The greening of planes, trains and automobiles

Moving goods and people around the world is responsible for a large part of global CO2 emissions(排放). As the world races to decarbonize everything, it faces particular problems with transportation—which accounts for about a quarter of our energy-related greenhouse gas emissions. Here􀆳s the breakdown of the emissions in 2018 for different modes of transport.

　　The fuels for transport need to be not just green, cheap and powerful, but also lightweight and safe enough to be carried around. Each mode of transport has its specific fuel needs. Much is still to be settled, but here are some of the solutions to get us going green.

　　This energy transition(变革) is global, and the amount of renewable energy the world will need is “a little bit mind-blowing,” says mechanical engineer Keith Wipke at the National Renewable Energy Laboratory. It􀆳s estimated that the global demand for electricity could more than double by 2050. Fortunately, analyses suggest that renewables are up to the task. “We need to speed up the development of green energy, and it will all get used,” says Wipke.

(　)21.What percentage of global transport emissions did road vehicles account for in 2018?

　　　　　 　　　　　 　　　　　

A.11.6%. B.45.1%.

C.74.5%. D.86.1%.

(　)22.Which mode of transport can go green comparatively easily?

A.Planes. B.Trucks.

C.Trains. D.Ships.

(　)23.What does Wipke suggest regarding energy transition?

A.Limiting fuel consumption.

B.Putting more effort into renewables.

C.Improving energy efficiency.

D.Making electricity more affordable.

【文章大意】 本文是一篇说明文。文章主要介绍了2018年不同交通方式的温室气体排放占比,以及飞机、汽车等各类交通工具的未来绿色燃料路径。

1.C　细节理解题。根据图表信息ROAD VEHICLES部分中“ROAD (PASSENGER) 45.1%”[道路(客运)45.1%]以及“ROAD (GOODS) 29.4%”[道路(货运)29.4%]可知,道路车辆总占比为(45.1%+29.4%=)74.5%,即道路车辆在2018年全球交通领域温室气体的排放中占比74.5%。故选C。

2.C　细节理解题。根据图表信息可知,飞机需依赖合成碳氢化合物，技术难度高；卡车依赖氢燃料电池，但绿色氢气生产成本高；轮船需使用难以点燃的液态氨，且需重新设计发动机，均存在明显障碍；而火车已有部分实现电气化，剩余部分电动化方式简单，是相对容易实
