问题      "I’ve been shot in the leg. I’ve been beat up. But that’s pretty minor," says a 41, year-old American security contractor who spent four years in Iraq. "But when you get a vehicle blown out from under you, it does tend to affect one a little bit."
    With a broken back, two broken feet and neurological(神经的) damage, the man, who asked that his name not be used, spent the next three months in hospitals in Iraq,, Germany and America. But though he was physically on the mend by the start of this year, he found himself incapable. "I was having nightmares," he recalls. "I couldn’t do anything. Mostly, I’d just stay in a room and not leave."
    Post Traumatic Stress Disorder (外伤后压性疾病), or PTSD, is the lasting of declining psychological symptoms. It can include flashbacks and nightmares, increased arousal in the form of insomnia(失眠), anger and an inability to concentrate, and impaired personal relationships. Although lasting psychological damage from horrific experiences has been recognized since time immemorial, it is only since 1980, when veterans were still experiencing stress from the Vietnam War, that PTSD has been a formal mental diagnosis.
    By 2005 72,000 American veterans were receiving disability payments for PTSD. A study two years later estimated that 12% of American veterans from the wars in Iraq and Afghanistan suffer from PTSD. Thus far, 1.8m Americans have been deployed in those two theatres, implying 216,000 eventual cases.
    Yet most PTSD sufferers are not drawn from the ranks of those for whom wound is an occupational hazard: 5 % of American men suffer from PTSD at some period in their lives. For American women, the rate is double that, mostly from exposure to such crimes as domestic violence and sexual abuse. Two in five rape victims are diagnosable with PTSD six months after the attack. "It can go on for ever", says Kathleen Brady, a professor at the Medical University of South Carolina who studies the disorder, "but even after 30 years, PTSD is treatable."
According to the study in 2007, the percentage of American veterans suffering from PTSD is about ______.
选项
答案12%
解析 由定位句可知，两年后的一项研究预测，参加过伊拉克和阿富汗战争的美国老兵中，会有12%的人员受到“外伤重压后紊乱”的困扰。根据定位句前一句的时间标志——2005年，可知这里A study two years指的是 2007年，因此2007年美国老兵受该病困扰的百分比是12%。
