英国零售业 一屏 逻辑很清晰 最开始几句不太重要。貌似说因为出生率增加和automobiles拥有量增加，使零售业发展很好。英国零售业发展更相似于西欧国家，而不是美国。开始说美国零售业的特点：美国是最先开始发展零售业的，发展的很好，主要原因是 进入壁垒低 labor便宜又丰富 rerail place便宜 政府监管松。 On the contrary 这里转折，开始说西欧国家的零售业，大概意思就是和美国零售业的特点相反啦（房租贵 监管多）英国是西欧中边际效益最高的，得益于政府监管强，进入壁垒高，还有那些老板的advanced manage system.但其实英国的效率不是最高（貌似是用sales of each employee计算） 最高的是德国。文中还有一句话是自从1980's 英国放宽监管，英国零售业有了个boost.最后一句话非常重要，有题，就是貌似作者认为英国零售业成功最重要的原因是因为房租太贵，然后别人付不起，就形成了进入壁垒。 Q1：问英国市场为什么more like EURO than USA 我选的是政府管制比较多 Q2：主旨题 我记不清了 反正有出现 英国 这个单词的 大概是B，C的位置 意思大概是比较英国和西欧美国的零售市场 Q3.英国的retailer收益高的原因 我选因为英国很少retailer可以付得起高的房租 在文中最后一句话定位
鉴定画这个 好好看这个~我觉得差不多诶 基本上内容都在的 说法也差不多 参考文献 （改写by luxiao417） In recent decades, art scholars, restorers and forensic specialists have relied increasingly on scientific techniques to determine the chemical composition of a work’s pigments to try to ascertain when, where and by whom it was likely made. One ostensibly ancient Virgin with Child painting was revealed to be a 1920s fake after testing revealed that it contained Prussian Blue, a pigment that was invented in the 1700s—long after the painting would have been made if it were original. Chemical processing of paint samples can provide useful molecular profiles, but it also means physically damaging a chip. Other methods using x-ray fluorescence, scanning electron microscopy and infrared spectroscopy have helped scholars and technicians peer into ancient paint, but they can be time- and labor-intensive. A new study shows how sound waves can detect a dozen different inorganic pigments using Fourier-transform photoacoustic infrared (PAIR) spectroscopy (which makes use of signal processing functions developed by French physicist Joseph Fourier). The process is based in part on an 1880 discovery by Alexander Graham Bell, who demonstrated that shining a modulated[调制的，调解的] beam of light onto an object could create a subtle[精巧的，精妙的] acoustic[听觉的] wave. "The behavior of paints, pigments, glazes, etc. depends critically on the conditions associated with their production, storage and long-term display," the researchers noted in their paper. "Without a full comprehension of the reactivity of the chemicals involved, the attempted preservation of artworks can sometimes lead to more damage than would occur by just simply leaving the works untreated." The researchers proposed that these simple readings could be included in a database for quick reference in the future. "Once such a database has been established, the technique may become routine in the arsenal of art forensic laboratories," Ian Butler, a chemistry professor at McGill University and coauthor of the new study, said in a prepared statement。 有问关于Bell这个人 以下哪个是真的：选那个(PAIR) spectroscopy base on 这个科学家的discovery 问第三段和第二段关系：选的researcher关于第二段work的commendation还是comments
