山西沁水县2017高考英语阅读理解选练（3）【科普知识型-阅读理解】Housed in Milan, one of Europes dirtiest cities, Leonardo da Vincis masterpiece The Last Supper still faces a threat from air pollution, researchers say, despite preventative measures that have significantly decreased pollutants in the church where the famous painting is on display.In 2009, Italian authorities installed a heating, ventilation (通风) and airconditioning system to protect the painting from Milans polluted air. To see whether the system could improve air quality, a team of researchers led by Constantinos Sioutas, a professor of civil and environmental engineering at the University of Southern California, placed two airquality monitors inside the church for a year to collect samples from around painting. Results showed the levels of fine and coarse particulates were reduced near the painting by 88 percent and 94 percent, respectively, compared with the corresponding outdoor levels. “Its a spectacular reduction，” Sioutas said in a statement. “It is, frankly, very impressive.”Although the researchers applauded the successful decrease in particulates around da Vincis painting, they warned that indoor sources of pollution may still pose a threat to the priceless painting. Fatty lipids (油脂) from the skin of customers in the church appeared in significant quantities around the painting, despite the fact that visitors getting access to the artwork are strictly regulated.Only a few visitors are allowed inside the church at a time, and they enter the building and can stay for only 15 minutes each. However, fatty lipids from visitors skin can combine with dust in the air and pollute the painting if they come in contact with it, says study researcher Nancy Daher of the University of Southern California.Even previous restorations of the painting may pollute its surface, Daher said. Tiny particulates of the wax applied during early repair efforts can be emitted from the painting, get into the air and tarnish (使失去光泽) the painting in the same manner as the fatty lipids.The researchers noted that their airsample analysis could be used as a point of reference for future studies aimed at protecting valuable artwork and artefacts.1What does the underlined word “particulates” in Paragraph 2 probably mean?AThe smallest parts of a chemical substance.BThings dirtier than usual.CCertain types of gas.DExtremely small pieces of dirt, which cause serious pollution.2According to the text, the following factors pollute the painting EXCEPT _Afatty lipids from the skin Btiny particles of the waxCbreath of the visitors Ddust in the air3According to the researchers, which of the following is NOT true of their airsample analysis?A.
