问题     It vanished in 2002, a result of a bad fall. As my neurosurgeon explained, when my head hit the ground, my brain sloshed around, which smashed delicate nerve endings in my olfactory system. Maybe they’ll repair themselves, she said (in what struck me as much too casual a tone), and maybe they won’t. If I had to lose something, it might as well have been smell; at least nothing about my personality or my memory had changed, as can happen with head trauma. So it seemed almost churlish to feel, as the months went on, so devastated by this particular loss.
    But I was heartbroken. My sense of smell was always something I took pleasure in. Without scent, I felt as ff I were walking around the city without my contact lenses, dealing with people while wearing earplugs, moving through something sticky and thick. The sharpness of things, their specificity, diminished. I couldn’t even tell when the milk had gone bad. Oddly, my sense of taste remained perfectly fine, but I was still nervous about opening a carton of yogurt without having someone nearby to sniff it for me. I had been stripped of the sense we all use, often without realizing it, to negotiate the world, to know which things are safe and which are dangerous.
    After nearly a year, I talked to a colleague savvying about neuro-science, who suggested I try to retrain my sense of smell on the assumption that the nerve endings had repaired themselves but that something was still broken along the pathway from nose to brain, where odor molecules activate olfactory receptors (the subject of this year’s Nobel-winning research). Her advice was to expose myself to strong, distinctive fragrances, asking the person I was with to tell me exactly what I was smelling even if I wasn’t conscious of smelling anything at all.
    I began sticking my nose into everything that seemed likely to have a scent—the cumin in the spice cabinet, freshly ground coffee, red wine. I interrupted friends midsentence if we happened to be walking past a pizza place or a garbage truck and asked, stupidly, "What are you smelling now?"
    Slowly, the smell therapy started to work. At first, distressingly, all I could smell were unnatural scents: dandruff shampoo, furniture polish, a cloud of after-shave from a stocky young man. The first time I smelled cut grass again, in the small park near the American Museum of Natural History, was almost exactly two years after my fall. It made me cry. The tears embarrassed me, but cut grass is one of those fragrances that transport me directly to the landscape of childhood. And that’s what I had been missing, really, and why getting back my sense of smell was so precious: a visceral connection to the person I used to be.

选项 A、the smash of delicate nerve endings
B、the loss of something
C、the change of personality and memory
D、the sense of smell

答案D

解析 本题是细节题。根据第1段作者的神经外科医生(neurosurgeon)的解释可以作出此判断:Ⅱ I had to lose something,it might as well have been smell.由此可知正确答案。
