问题     Elite memory athletes are not so different from their peers in any other sport: They face off in intense competitions where they execute seemingly superhuman feats such as memorizing a string of 500 digits in five minutes. Most memory athletes credit their success to hours of memorization technique practice. One lingering question, though, is whether memory champs succeed by practice alone or are somehow gifted. Recent research suggests there may be hope for the rest of us. A study, published today in Neuron, provides solid evidence that most people can successfully learn and apply the memorization techniques used by memory champions, while galvanizing large-scale brain changes in the process.
    A team led by Martin Dresler at Radboud University in the Netherlands used a combination of behavioral tests and brain scans to compare memory champions with the general population. It found top memory athletes had a different pattern of brain connectivity than controls did, but also that subjects who learned a common memorization technique over a period of weeks, not years, greatly improved their memory skills, and began to exhibit brain connection patterns resembling those of elite memorizers.
    Many of us learn new skills throughout our lives, and scientists have long wondered if and how our brains change as a result. Previous research has linked some skills to specific brain changes. One well-known set of studies showed that London taxi drivers developed more gray matter in their hippocampi (a brain area linked to memory) as they acquired the knowledge needed to navigate London’s haphazard maze of streets. Dresler and colleagues, motivated in part by co-author and professional memory trainer Boris Konrad, decided to focus on elite memory athletes who utilize memorization techniques to compete at highly specific tasks such as memorizing decks of cards or lines of binary digits in minutes. They wanted to know whether these highly skilled practitioners exhibit noticeable brain changes and how those changes occur.
    James McGaugh, a neurobiologist at the University of California, Irvine, who was not involved in the study, considers it to be in a similar vein as the London taxi cab research, but highlights an important difference: Rather than pinpointing a particular brain region, the present study found an overall change in brain connections. "All of our brains are malleable all the time, and this is just another piece of evidence of that," he says. "If you learn something and you learn it well, the brain changes. A super memory follows.
James McGaugh’s remarks is noted to suggest that________.
选项 A、An idle brain is the devil’s workshop
B、You can acquire a super memory too
C、No practice, no gain in one’s wit
D、A wise man changes his mind, a fool never will
答案B
解析 本题是主旨题。根据题干定位至末段。麦戈高夫提到“虽然在大脑局部变化还是整体变化方面有些分歧，但研究证明‘大脑是可塑的’；掌握好技能，大脑会变化”。说明，通过训练可以改变大脑，提高记忆能力。故答案选B。A项“游手好闲是万恶之源”；C项“吃一堑，长一智”和D项“智者通权达变，愚者刚愎自用”均不符合文意，故排除。
