问题    Humans are the only species known to have consciousness, awareness that we have brains and bodies【C1】______adaptability that we can affect the course our lives take, that we can make choices【C2】______that vastly affect the quality of our lives—biologically, intellectually, environmentally, and spiritually. As humans, we have the ability to mold our【C3】______beings to become what or who we wish to become. While some of us may,【C4】______, have genetic and biological imperatives that may require medication or training to overcome, or at least to modulate, the vast majority of us do, in fact, hold our emotional【C5】______in our hands.
   All that【C6】______, until the last decade, scientists believed that the human brain and its connections were formed during gestation and infancy and remained【C7】______unchanged through childhood. They believed that humans had a given number of neurons in a specific brain structure, and【C8】______the number might vary among people, once you were done with childhood development, you were set in this【C9】______. Your connections were already made, and the learning and growing period of your brain was over. In the last decade, however, researchers have found【C10】______evidence that this is not so, and that something called neuroplasticity continues throughout our lives.
【C8】
选项 A、while
B、despite
C、nevertheless
D、since
答案A
解析 本题考查逻辑关系。while放在句首，表示让步，放在句中表示对比；despite“尽管”，表示让步，后面连接的是that从句；nevertheless“然而”，表示转折，放在句中时往往用标点隔开；since“因为，既然”，表示因果。“They believed that humans had a given number of neurons in a specific brain structure”讲道，科学家们相信在人类某个大脑结构中存在一定数量的神经元。and后的句子中含有两个信息的缺失，需要我们找到语义线索来确定逻辑关系。vary“变化”，done with childhood development“童年发展完成”，be set“定型”，有以上三个重点线索可知，这里的逻辑关系应该为“虽然……变化，但是一旦完成童年发展，你就会……成型”。因此这里应该选择表示“尽管”的连词。因引导句子，故while是正确答案。
