问题                     Time to Stop Traveling by Air
    Twenty-five years ago a young British man called Mark Ellingham decided that he wanted a change of scenery. So he went to Australia, stopping off in many countries in between. He also decided to write about the experience and produced a guide for other travelers making similar journeys.
    In 1970,British airports were used by 32 million people. In 2004,the figure was 216 million. In 2030,according to government forecasts, it will be around 500 million. It’ s a growth driven by the emergence of low cost airlines, offering access to all parts of the world for less than ￡100.
    This has made a huge contribution to global warming. One return flight from Britain to the US produces the same carbon dioxide(二氧化碳)as a year’ s motoring(驾车). A return flight to Australia equals the emissions(排放)of three average cars for a year. And the pollution is released at a height where its effect on climate change is more than double that on the ground.
    Mark Ellingham built his business on helping people travel. Now he wants to help people stop—at least by air.
    He is calling for a ￡100 green tax on all flights to Europe and Africa, and ￡250 on flights to the rest of the world. He also wants investment to create a low-carbon economy, as well as a halt to airport expansion.
    Mark Ellingham’s commitment is important because his readers aren’ t just the sort of young and adventurous people who would happily jump on a plane to spend a weekend exploring a foreign culture. They are also the sort of people who say they care about the environment. It’ s a debate that splits people down the middle.
    The tourist industry has responded by offering offsetting(补偿)schemes. A small increase in the price of a ticket is used to plant trees.
    But critics say that it is not enough to just be carbon neutral. We should be actively cutting back on putting greenhouse gases into the atmosphere. And for the average person, making a plane journey will be his or her largest contribution to global warming. It may be good to repair the damage we do. But surely it is better not to do the damage in the first place.
A round trip flight from Britain to Australia produces the same amount of carbon dioxide as three average cars do in a year.
选项 A、Right
B、Wrong
C、Not mentioned
答案B
解析 题干：从英国到澳大利亚往返飞行的二氧化碳排放量与三辆普通小汽车一年内的排放量是一样的。由第三段第三句话“A return flight to Australia equals the emissions of threeaverage cars for a year”可知，返航到澳大利亚所产生的二氧化碳排放量等于三辆普通小汽车一年的排放量，而不是往返的航班。故题干表述错误。
