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."

选项 A、irregular
B、better
C、normal
D、worse

答案D

解析 词汇题(词义选择)。分析此题所在句子的上下文:上句为Recent research suggests that nerve cells lose efficiency and that there’s less activity in the brain.“研究表明脑细胞丧失效率,大脑活动减少”;再看空格所在句子:But,cautions Barry Gordon,‘It’s not clear that less activity is 33.”,同时前后两个句子有转折关系;再看下旬A beginning athlete is more easily winded than a 34 athlete.“初学的运动员比(技术娴熟的,有经验的,经过训练的)运动员更容易气喘吁吁”,本句是对空格所在句子的例证。由此推断,空格所在句子意在表达“大脑活动减少是正常的”之意,即大脑活动减少是否有什么不好尚不清楚。由此确定本题答案为D项worse“更糟糕”。
