问题     Advancing age means losing your hair, your waistline and your memory, right? Dana Denis is just 40 years old, but【C1】______ 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【C2】______ 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【C3】______ you remember? Well, sort of. But as time goes by, we tend to blame age【C4】______ 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【C5】______ " In fact, the 70-year-old may have been【C6】______ things for decades.
    In healthy people, memory doesn’t worsen as【C7】______ as many of us think. "As we【C8】______ , the memory mechanism isn’t【C9】______ ," says psychologist Fergus Craik. "It’s just inefficient."
    The brain’s processing【C10】______ slows down over the years, though no one knows exactly【C11】______ Recent research suggests that nerve cells lose efficiency and【C12】______ there’s less activity in the brain. But, cautions Barry Gordon, "It’s not clear that less activity is【C13】______ A beginning athlete is winded (气喘吁吁) more easily than a【C14】______ athlete. In the same way,【C15】______ the brain gets more skilled at a task, it expends less energy on it. "
    There are【C16】______ you can take to compensate for normal slippage in your memory gears, though it【C17】______ effort. Margaret Sewell says: "We’re a quick-fix culture, but you have to【C18】______ to keep your brain【C19】______ shape. It’s like having a good body. You can’t go to the gym once a year【C20】______ expect to stay in top form."
【C15】
选项 A、as
B、till
C、though
D、yet
答案A
解析 逻辑关系。根据In the same way可以确定，本句和上一句话是一种并列关系，所以本句的意思应该是“同理，随着大脑在某一工作上变得更加熟练，它就会花更少的精力在上面”。as可以引导时间状语从句，表示“随着”的意思，所以A项正确。B项till(直到)，C项though(虽然，尽管)，D项yet(但是)，均不合题意。
