实际上,这个国外早就做过实验的了,结论是学第二语言越早越好,我们家半岁开始。你用“kids Second Language” 作为关键字在google上查就会有相关的资料的,不要在百度上查,百度上国外资料很少的。
Everyone agrees – the primary years are the best in which to learn a second language.
The best time to teach your child a second language is the same time she's learning her first one.
Older learners lose the ability to hear and reproduce new sounds by age 8-12, according to experts, resulting in a permanent foreign-sounding accent in any language. Younger learners benefit from flexible ear and speech muscles that can still hear the critical differences between the sounds of a second language, as well as reproduce them with native-like quality.
