问题     Today, world leaders are discussing climate change and what—if anything— can be done to combat global warming. Extreme weather conditions have brought home the fact that our climate is changing—and changing fast. It may be easy to be fatalistic about it, but the truth is that although we humans have caused the problem, we also have the solution. "Think global and act local," said Friends of the Earth founder David Bower. In many small but important ways we can make a difference. Here are my top tips for how to begin:
    Count your food miles. What you eat and where you buy it affects global emissions. Pollution from transport is the fastest growing source of carbon dioxide emissions, so it is madness to fly out-of-season vegetables across the world to supermarkets. We should lobby supermarkets for a system of classifying food according to the distance traveled: 0 for local food, 1 for British, 2 for Europe, and 3 for intercontinental.
    Turn off anything that winks at you. A video recorder on standby uses almost as much electricity as one playing a tape. Turning down the thermostat by one degree, not leaving TV and music centers on standby, turning off lights, putting lids on cooking pots, and only half-filling kettles can cut energy consumption by 30%, saving your money as well as saving the planet.
    Just stop using petrol. Yes you can, and the car industry may(eventually)help you. Hydrogen-powered cars are loved by car designers and could become a reality in about 10 years. Meanwhile, consider converting to liquefied petroleum gas(LPG). You won’t be alone: a new pump for this is opening every day. Meanwhile, you can cut down on conventional petrol use just by changing driving habits—no rapid acceleration, lower speeds, keeping tires at the right pressure.
    Well, you can always walk. Or cycle. The majority of car journeys are less than five miles and, honestly, once you’ve stepped out, you’ll find it’s really not that bad. The only energy used is your own and that’s healthy. You only have to look at the collective strength of the people’s fuel lobby to know this makes sense.
    These changes will save your money which you should invest in an ethical saving account. They are profitable and they put the pressure on business to clean up its act.
At present, to replace petrol-driven cars, people may choose cars driven by______.
选项 A、electricity
B、LPG
C、hydrogen
D、biofuel
答案B
解析 第四段主要讲的是通过使用其他能源或改变驾驶习惯减少汽油的使用量。第三句说氢气驱动的汽车大约十年之后能够成为现实，但目前还不行。第四、第五句的意思是可以考虑使用液化气，而且已经有很多人开始这样做了：每天都会有新开的油泵。
