　　Ⅱ.阅读理解

　　19­year­old Danny Bowman once spent 10 hours a day taking selfies (自拍). Now the British teen is speaking out against the real dangers of selfie addiction.

　　His addiction started at age 15 and quickly went out of control, leading him to attempt to kill himself due to anxiety that he couldn't take the perfect selfie.

　　"I was constantly in search of taking the perfect selfie and when I realised I couldn't, I wanted to die，" he tells Daily Mirror about his 200 selfies­a­day addiction. "The only thing I cared about was having my phone with me so I could satisfy the desire to take a picture of myself at any time of the day."

　　His mother sought help, which eventually led to him being diagnosed with obsessive compulsive disorder (强迫症)．

　　"I lost my friends, my education, my health and almost my life，" Bowman explains.

　　At Bowman's worst, he would cut class three times an hour to take a selfie, and eventually dropped out of school at age 16, at which point his health started to fall apart. "I would limit myself to an apple and a bowl of rice a day in a bid to be thinner and improve my skin，" he says.

　　He didn't leave his house for six months due to anxiety about how he looked.

　　Selfie addiction is a phenomenon that increasing numbers of mental health professionals are recognizing. "Danny's case is particularly extreme，" says Dr. David Veal. "It's a mental health one which can lead to serious problems."

　　Bowman is believed to be Britain's first case and now receives regular treatment to help him deal with his technology addiction. "I think this kind of thing can happen to anyone, for me it showed itself in selfies; it could be something different for someone else，" he says.

　　语篇解读：英国的Danny Bowman因为过度玩自拍，一度精神抑郁，有自杀倾向。
