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.
【C7】
选项 A、more or less
B、pretty much
C、as ever
D、if any
答案B
解析 more or less“或多或少”，pretty much“十分，非常”，as ever“和以往一样”，if any“即使有的话也……”。该句的下文说，科学家们认为一旦人脑成型，神经元便会保持稳定。由此信息便可回溯到空格中应该为pretty much unchanged，意思是“保持高度稳定”。
