你这纯粹是在臆想。我的中国朋友和同事家里,小孩都是双语,没有问题。 老美这里的育儿书,都是提倡早期双语教育。这已经是常识了:小孩学习 语言的能力很强,正是学习语言的那时候。正常的小孩,学习两种语言, 根本不是负担。而且,有不少研究表明,学习双语,对小孩的智力发展 有正面影响。 http://www.parenting-journals.com/297/being-bilingual-is-it-rig What is the best age for beginning to teach my child a second language? Ages 6 months to 4 years are the optimal age for beginning to acquire a second language. Children who receive early intensive exposure to two languages can quickly and almost effortlessly acquire both languages simultaneously. At young ages, children can grasp a new language in the same way as they acquire their first language and won’t translate from their first language, as do older children. Young bilingual children have a linguistic and a cognitive advantage over monolingual children (they develop more synapses in the brain and are cognitively more flexible).
