问题     Advancing age means losing your hair, your waistline and your memory, right? Dana Denis is just 40 years old, but【1】she’s worried about what she calls "my rolling mental blackouts." "I try to remember something and I just blank out," she says.
    You may【2】about these lapses, calling them "senior moments" or blaming "early Alzheimer’s(老年痴呆症)". Is it an inescapable fact that the older you get, the【3】you remember? Well, sort of. But as time goes by, we tend to blame age【4】problems that are not necessarily age-related.
    "When a teenager can’t find her keys, she thinks it’s because she’s distracted or disorganized," says Paul Gold. "A 70-year-old blames her【5】." In fact, the 70-year-old may have been【6】things for decades.
    In healthy people, memory doesn’t worsen as【7】as many of us think. "As we【8】, the memory mechanism isn’t【9】." says psychologist Fergus Craik. "It’s just inefficient."
    The brain’s processing【10】slows down over the years, though no one knows exactly【11】. Recent research suggests that nerve cells lose efficiency and【12】there’s less activity in the brain. But, cautions Barry Gordon, "It’s not clear that less activity is【13】. A beginning athlete is winded (气喘吁吁)more easily than a【14】athlete. In the same way,【15】the brain gets more skilled at a task, it expends less energy on it."
    There are【16】you can take to compensate for normal slippage in your memory gears, though it【17】effort. Margaret Swell says: "We’re a quick-fix culture, but you have to【18】to keep your brain 【19】shape. It’s like having a good body. You can’t go to the gym once a year【20】expect to stay in top form."
【14】
选项 A、famous
B、senior
C、popular
D、trained
答案D
解析 词汇题(词义选择)。空格所在句子是：A beginning athlete is winded(气喘吁吁)more easily than a 34 athlete．，由than可以看出本句是要把两类运动员相比较。比较的主体是a beginning athlete，比较的内容是“更容易气喘吁吁”，所以比较对象应该是技术娴熟的，有经验的，经过训练的运动员。A项famous意为“著名的”，不符合题意；B项senior意为“年长的，资格老的”，虽然该词在第2段出现过，但是我们想想：新手(一般是年轻的)比资格老的(一般是年长的)更易气喘吁吁吗?这是反自然的，所以不符合题意；C项popular意为“流行的，受欢迎的”，不符合题意；D项trained意为“经专门训练的，训练有素的”符合题意，为本题答案。
