问题     Children whose minds wander might have sharper brains, research suggests.
    A study has found that people who appear to be constantly【C1】______have more "working memory", giving them the ability to hold a lot of information in their heads and【C2】______it mentally.
    Children at school need this type of memory on a daily basis for a variety of tasks, such as【C3】______teachers’ instructions or remembering dictated sentences.
    During the study, volunteers were asked to perform one of two simple tasks【C4】______which researchers checked to ask if the participants’ minds were wandering.
    At the end, participants measured their working memory capacity by their ability to【C5】______a series of letters interspersed with simple math questions.
    Daniel Levinson, a psychologist at the University of Wisconsin-Madison in the United States, said that those with higher working memory capacity reported "more mind【C6】______during these simple tasks", but their performance did not suffer.
    The results, published online in the journal Psychological Science, appear to【C7】______previous research that found working memory allows humans to juggle multiple thoughts【C8】______.
    Dr Jonathan Smallwood, of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig, Germany, said: "What this study seems to suggest is that, when circumstances for the task aren’ t very difficult, people who have【C9】______working memory resources deploy them to think about things other than what they’ re doing."
    Working memory capacity is also【C10】______with general measures of intelligence, such as reading comprehension and IQ scores, and also offers a window into the widespread, but not well understood, realm of internally driven thoughts.
A)following B)wandering C)from D)sequentially
E)associated F)during G)focusing H)distracted
I)remember J)confirm K)conflicting L)manipulate
M)concentrative N)additional O)simultaneously
【C4】
选项
答案F
解析 空前的句子结构完整“在研究过程中，研究人员让志愿者执行两个简单任务的其中之一”，空后句子意为“研究者不时询问参与者是否在走神”。前后两句关系是“在执行任务期间，研究者不时询问参与者是否在走神”。故此处应填during，与which结合构成“介词加关系代词”结构的定语从句。因此选择during。
