People appear to be born to compute. The numerical
skills of children develop so early and so inexorably that it is easy to imagine
an internal clock of mathematical maturity guiding their growth. Not long after
learning to walk and talk, they can set the table with impressive accuracy one
plate, one knife, one spoon, one fork, for ’each of the five chairs. Soon they
are capable of noting that they have placed five knives, five spoons, and five
forks on the table and, a bit later, that this amounts to fifteen pieces of
silverware. Having thus mastered addition, they move on to subtraction. It seems
almost reasonable to expect that if a child were secluded on a desert island at
birth and returned seven years later, he or she could enter a second-grade
mathematics class without any serious problems of intellectual
adjustment. O A. Children naturally and easily learn mathematics. B. Children learn to add before they learn to subtract. C. Most people follow the same pattern of mathematical development. D. Mathematical development is subtle and gradual. [单项选择]患者,男,63岁,突发意识障碍,能唤醒,醒后可简单回答问题及勉强配合检查,停止刺激即又入睡,这种意识状态是()
