导语：为了对抗印度德里严重的空气污染，拥有“纯净空气”的酒吧应运而生。它由阿雅维尔·库马尔(Aryavir Kumar)创立。 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 first­ever 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 is placed near the customer's nostrils through which they are advised to breathe in the oxygen. The bar also offers its customers several aromas 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 back­to­back 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 so­called 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 money­driven.” 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 recently as the pollution levels were high. 【词海拾贝】 1．measure n．测量；措施；程度 vt.测量；估量；权衡 2．breathe vi.呼吸 3．improve vt.改善，增进；提高……的价值 4．claim v．宣称；要求；索取n.声称；(财产等)所有权 5．relaxed adj.放松的 6．regularly adv.定期地；有规律地 7．encourage vt.鼓励 8．concept n．观念，概念 9．sceptical adj.怀疑的 10．significant adj.重大的；有意义的 【译文助读】 在对抗印度德里严重空气污染的所有措施之间，还有一个选择——拥有“纯净空气”的氧气吧。 由阿雅维尔·库马
