只了解弊端,弊端就是进入学校后小孩可能因为以前学的英语而自得,反而影响了正常学英语. 完了,没有注意到要用英语回答... The disadvantage is that the child would be proud of what he or she has learnd before,so... that,maybe he or she can not make minds to the English the teacher taught at school.(不接触英语很久了,如有语法错误请网友们批评指正.)

个人以为毫无用处，而且剥夺了孩子游戏的时间。

容易忘了母语,比如有个小孩去外国去留学,最后连中国话也忘了,英语也没学利索.分给我吧
