高中英语阅读，求老师解答

选择C，因为作者看到现在的孩子那么早熟，比他们那个年代的孩子比言行举止成熟，Children don’t seem childlike anymore．Children speak more like adults, dress more like adults and behave more like adults than they used to. 得以体现，然后后面作者就说了一堆人成长需要什么样的过程，需要按照程序走，Whether this is good or bad is difficult to say, but it certainly is different表达作者觉得有点不妥但是又不知说什么，所以表现出的是upset

This incident stuck in my mind because it confirmed （确认） my growing belief that children are changing. Undoubtedly a change in children has increased steadily in recent years．这两个句子后面说的都是具体改变的比较。Whether this is good or bad is difficult to say, but it certainly is different．Childhood as it once was no longer exists．说明作者对于这种变化持有批判的态度。但是后面没有具体说是快速的社会发展Human development is depended not only on born biological states, but also on patterns of gaining social knowledge。
