多少年来存在一种说法,总认为成年人很难学好外语。这种观念在一定程度上不可避免地给成年人学习外语带来心理压力,使之成为一种精神负担,学习动力受到影响。但是近几年语言学家的客观研究和教学实践证明,这种成人学不好外语的说法是缺少依据的。从成人的生理成熟和心理机能发展的角度看,一般成人大脑皮层的140多亿个神经细胞,可以组合成亿万个复杂的神经网络,大脑两半球每秒钟可以完成40亿次神经冲动,一生能贮存1000亿个信息单位。根据一些生理学家的研究,当今人类的大脑,至多只开发了5—10%,潜伏着巨大的学习能力。同时,成年人还具有学习目的明确,逻辑思维发达,理解力、自学能力强,持续力强,认知心理和自我调节水平较高等
For years there has been a saying that it is difficult for adults to learn a foreign language. To a certain extent, this kind of concept inevitably brings about psychological pressure on adults to learn foreign languages, making them a spiritual burden and learning motivation affected. However, in recent years, the objective studies and teaching practices of linguists have proved that this theory of adult learning is not good for foreign languages. From the point of view of adult’s physical maturity and psychological development, more than 14 billion neurons in the adult cerebral cortex can be combined into hundreds of millions of complex neural networks. The two hemispheres of the brain can accomplish 4 billion nerve impulses per second, Life can store 100 billion units of information. According to the research of some physiologists, the human brain is only developed 5-10% at most, which lurks great learning ability. At the same time, adults also have a clear learning purpose, logical thinking developed, understanding, self-learning ability, sustained ability, cognitive psychology and self-regulation of a higher level
