每当我们看到婴儿那充满生命气息的纯真笑容时,谁都会从内心感到一种说不出的喜悦,仿佛自己也回到那天真无邪的往日。然而,不知从何时起失去笑容的婴儿却悄然出现,并且越来越多。他们没有笑声和啼哭,呆滞的目光既无生气又无表情,只是静静地傻呆着。这些老气横秋的婴儿被专家称做沉默的婴儿。 Whenever we see the innocent baby’s innocent smile, everyone will feel an indescribable joy from the heart, as if he himself has returned to that innocent past. However, I do not know when to lose the smile of the baby quietly appeared, and more and more. They did not laugh and cry, sluggish eyes neither angry nor expressionless, just quietly stupid. These old-fashioned babies are called silent babies by experts.
