11．XI'AN-China has introduced various emergency responses and longterm measures against air pollution in the central and eastern regions．
The air quality index （AQI） for Xi'an reached 500on Wednesday afternoon，at the top of the AQI scale，according to the national air quality monitoring website．Xi'an weather forecasters predict the smog （霧霾） will continue for the next week and air pollution may worsen．
"I have to keep buying masks for my family，"said Liu，buying masks at a pharmacy （藥店） near her home in downtown Xi'an．"This is the only thing we can do to protect ourselves．"
On Wednesday，a city government emergency response plan was put into action，suspending all the construction and taking at least 50percent of government vehicles off the road．Power plants must limit their output and reduce emissions．
Nearly half the country，more than 100cities in 20provinces，has suffered from smog since last December．Many have taken action，including experimenting with artificial methods to reduce smog，limiting vehicle use and fining polluters．
Assessments based on GDP alone were abandoned last month and more emphasis has been put on public wellbeing and the environment．Whether the move will be effective in forcing local governments consider environmental issues over economic growth remains to be seen．Environmental protection professionals are doubtful about the immediacy of the effects of these measures．
Xiao Hang，an urban researcher at the Chinese Academy of Sciences，said it took London 50years to lose the moniker （綽號）"foggy London town"and Los Angeles still struggles to control its photochemical （光化學） smog．""We can't ignore environmental problems during the development process and China has a long way to go．"he said．

分析 本文是一篇關于中國采取措施整治環境污染，減少霧霾的新聞報道．在文中作者提到了西安的空氣質量，提到了西安市民以及政府對此采取的應對措施．也提到了國家為了整治環境污染而采取的措施，并且指出整治污染是一個長期的過程．
解答 41．B．主旨大意題．本文是新聞報道，在文章首段提出中心，即：中國已經啟動緊急預案和并且采取長期措施來應對霧霾天氣，由此判斷C選項內容更能體現文章中心，故選B．
42．C．詞義猜測題．根據第四段a city government emergency response plan was put into action，可知后文是對緊急應對計劃的解釋，由此推斷應該是停止正在建設的項目，以減少污染，故選C．
43．A．細節理解題．根據文中"Assessments based on GDP alone were abandoned last month and more emphasis has been put on public wellbeing and the environment．"可知，基于GDP的評估對環境保護是有害的，這才廢除．故選A．
44．A．推理判斷題．根據文章最后一段中"We can't ignore environmental problems during the development process and China has a long way to go，和對倫敦治理霧霾的漫長過程可知解決環境問題需要人們付出很大的努力，故選A．
45．C．推理判斷題．仔細閱讀全文可知，這是一篇新聞報道，最有可能是在報紙上．故選C．
