倾听一个孩子开始“学”讲“话”的时候,谁都能注意到,他或她所掌握的“词”是非常有限的。常常被人们忽略的是小孩子们“成就”的“量”。仅仅学“词汇”已是一项巨大的任担。在开始讲话后几年间,一个孩子每天要“学”的“生字”,在超过十个以上!可是小孩子怎样办到的,我们还知道得很少。不用说他们绝对不是采取象背“字典” When one listens to a child and begins to “learn” about “words,” everyone can notice that the “word” he or she has is very limited. Often overlooked is the “amount” of children’s “achievement.” Merely learning vocabulary is a huge undertaking. In a few years after starting to talk, a child learns more than ten words a day, but we know very little how children do it. Needless to say they are definitely not taken like back “dictionaries”
