问题    Visiting Oxford Street, a road filling with tatty shops and overcrowded with people, is plainly a trial. Less plainly, levels of nitrogen dioxide (NO2) , a noxious gas, have been found to be around three times higher there than the legal limit. In 2013 the annual mean concentration of NO2 on the street was one of the highest levels found anywhere in Europe.
   British air is far cleaner than it was a few decades ago. Fewer people use coal-burning stoves; old industrial plants have been decommissioned. But since 2009 levels of nitrogen oxides and particulate matter, coarse or fine particles that are linked to lung cancer and asthma, have fallen more slowly. The exact number of deaths caused by dirty air is unknown. But in 2010 a government advisory group estimated that removing man-made fine particulate matter from the atmosphere would increase life expectancy for those born in 2008 by an average of six months.
   Much of the slowdown is the result of fumes from diesel cars, which were championed by successive governments because they use less fuel and thus produce less carbon dioxide than petrol cars. In 2001 only 14% of all cars ran on diesel; by 2013 the proportion had increased to 35%. (Greener "hybrid" and electric cars have increased nine fold since 2006, but account for just 0. 5% of the entire fleet.) Second-hand cars are particularly noxious, but even newer ones have not been as clean as hoped. Many cars that let out few pollutants in tests produced more on the roads.
   Government’s hesitation has not helped. Part of the problem is that several departments are responsible for air pollution. This means nobody has taken a lead on it, complains Joan Walley, a Labour MP who chairs an environmental committee that has released a series of damning reports. And few politicians are keen to fire drivers.
   However, some improvements have been made. In 2008 a "low-emission zone" was created in London, which targets large vans and coaches. A smaller "ultra low-emission zone" has been proposed for 2020, which would charge all vehicles that are not of a certain standard 12. 50 pounds a day. European Commission fines for breaching limits may encourage cities to do more. But other countries are more ambitious; 60 such zones exist in Germany, targeting private cars as well as vans. In December Anne Hidalgo, the mayor of Paris, announced that she wanted to ban diesel cars by 2020.
Considering the role that government plays, the author seems to be______.
选项 A、sympathetic
B、pessimistic
C、concerned
D、objective
答案D
解析 态度题。定位到最后两段。第四段首句提到Government’s hesitation has not helped．其中not helped明显是否定、负面的表达。第五段首句提到：However，some improvements have been made．其中，However突出作者的观点态度，该句明显是正面、肯定的表达，故作者对于政府举措的描述有正有负，属于客观态度。选项[A]sympathetic“同情的”；[B]pessimistic“悲观的”；[C]concerned“担心的”；[D]objective“客观的”。综上分析，本题选[D]。
