阅读理解. Mayor Boris Johnson Monday outlined plans to make London 'the cleanest, greenest city on Earth' by the 2012 Olympics and called for commitments from other world cities at a climate change conference. Leaders of the world's 40 largest cities are meeting in Seoul this week for a summit on combating global warming -- the third to be held since 2005. 'What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine (内燃机),' said Johnson. He said at a press conference the world's cities consume 75 percent of the world's energy and produce 80 percent of the emissions which cause climate change. 'The problem of our planet is an urban problem,' Johnson said. He said the British capital wants to use the Olympics 'to drive the greening and the improvement of our city' and noted that London is committed to reduce carbon dioxide emissions by 60 percent by 2025. Johnson said the key measure was being taken to solve problems relating to housing and commercial buildings, which accounted for 70 percent of carbon dioxide emissions in London. This involved retrofitting (翻新) -- installing lagging -- in large numbers of public buildings. Johnson proclaimed himself a 'passionate cyclist' and said he would push ahead with cycle superhighways around London. London's air quality problem, he said, was caused by vehicle emissions from 8,300 worn and used diesel (柴油) buses, which could be replaced by low-carbon vehicles. In addition, there were also 32,000 taxis running on diesel fuel, which could be replaced by electric vehicles. Johnson said there would be a few programs in the next few years to produce a 'cleaner, greener' bus for the city. 'The age of the diesel bus has got to be over in London.' 1. Which would be the best title for the passage?______ A. The third summit on global warming B. London plans to make the cleanest and greenest city on Earth by 2012 C. Some measures to deal with pollution D. The problem of our planet appeared 2. Which of the following statements is NOT TRUE according to this passage.'?______ A. London's air quality will be improved in the near future. B. The used buses running on diesel will be replaced by electric vehicles. C. London promises to reduce carbon dioxide emissions by 60 percent by 2025. D. Something has been done to solve the problem of carbon dioxide emissions. 3. What does the underlined word mean in the first paragraph?______ A. Resisting. B. Objecting. C. Agreeing D. Solving 4. The topic of the meeting in Seoul might be______ A. climate change B. global warming C. London Olympics in 2012 D. green environment 5. If the passage was continually written, the following might be _____. A. measures to end the age of the diesel bus B. measures to reduce carbon dioxide emissions in London C. measures to solve housing and commercial items D. measures to replace the old and used vehicles
