In between all the measures to battle the severe air pollution in Delhi, India, there’s one more option — a bar that has “pure air”.
Founded by Aryavir Kumar, Oxy Pure, Delhi’s first-ever oxygen bar, offers 15 minutes of 80-90 percent pure oxygen, costing Rs 299 ($4.2). Customers are given a lightweight tube for oxygen intake. The device (装置) is placed near the customer’s nostrils (鼻孔) through which they are advised to breathe in the oxygen.
The bar also offers its customers several aromas (气味) to go with oxygen, including lemongrass, cherry and more. According to the aroma people choose, each session promises to improve sleep patterns and digestion, cure headaches, and even claims to work as a treatment for depression.
Bonny Irengbam, a senior sales assistant at the bar, said, “Some people, who try it for the first time, will feel relaxed and fresh. But only people who do this regularly will get real benefits. By regularly, I mean once or twice a month. We don’t encourage back-to-back sessions, as increased levels of oxygen in the body can make a person dizzy.”
Dr. Rajesh Chawla, a senior doctor at the Indraprastha Apollo Hospital, said, “Even if you breathe in the so-called pure oxygen for two hours in a day, you will go back to breathing the polluted air for the rest of the 22 hours. The concept is purely money-driven.”
Recalling the first few months of the bar, Irengbam admitted that people were sceptical. “Many people criticised, saying we were selling air. Others were simply scared to breathe through the tube.”
Irengbam said the bar saw a significant rise in the number of customers two to three days after Diwali, an Indian festival mainly celebrated by fireworks and lights, as the pollution levels were high.

【分析】
这是一篇说明文。介绍了在印度为了应对环境污染开的“氧吧”，以及人们对此的看法。
12．细节理解题。根据倒数第二段第一句“Recalling the first few months of the bar,Irengbam admitted that people were sceptical. ”回想最初几个月，Irengbam承认人们持怀疑态度。可知“氧吧”一开始受到人们的质疑，所以一开始并没有被很好地接受。故选C项。
13．词义猜测题。根据第四段中“But only people who do this regularly will get real benefits.By regularly,I mean once or twice a month。”可知，一月吸氧一次或者两次是有益于健康的，而后文中作者不鼓励“back to back”，因为这样会增加氧气水平从而让人眩晕。通过语境可知 “back to back”应是“常常，连续不断”的意思，因为连续不断地吸入纯氧会导致氧气水平上升，让人眩晕。D. One-after-another(连续地)符合以上猜测，故选D项。
14．推理判断题。根据倒数第三段中“Even if you breathe in the so-called pure oxygen for two hours in a day,you will go back to breathing the polluted air for the rest of the 22 hours.The concept is purely money-driven”可知，Dr.Rajetha Chawla认为即使一天呼吸两个小时所谓的“纯氧气”，剩下22个小时都呼吸污染的空气，那这个完全就是受金钱驱使的概念。由此推知，他对“氧吧”持怀疑的态度。故选A项。
15．推理判断题。根据第一段“In between all the measures to battle the severe air pollution in Delhi, India, there’s one more option — a bar that has ‘pure air’”可知，在针对印度德里严重的空气污染采取的所有措施之中，还有另一种选择，拥有“纯净空气”的“氧吧”。并结合全文理解可知，文章是介绍为了应对环境污染在印度开的“氧吧”。由此推知，文章的目的是介绍印度的第一所“氧吧”。故选B项。
