Hardly a week goes by without another (any) reports of education appearing in the media. Some people think that it's better for children to study a new language at primary school rather than when they are in their teens. As far as I'm concerned, the benefits of it worth than the cons. (Learning a new language is definitely a good thing to do for children. However, some people claim that it is better as the foreign language is started to teach at primary school rather than secondary school. In my opinion, the benefits of that far outweights the cons.)
First of all, studying at a young age will help children with their English skills. They have more time to practice, study and broaden their knowledge. The chances are that they will accumulate experience perfectly. It's no doubt that time has good influences on the children's English. Secondly, studying a new language means having a new feeling, part of life; which helps you to explore new things. You will definitely see new innovations. Therefore, it worths learning at a young age.
In contrast, if the children know too much about their new language, they'll forget their mother-tongue one. He or she hasn't studied enough about their hometown's language. Nevertheless, it wouldn't have a negative impact on the children. If the children study efficiently, it's possible that they'll learn both languages well. For example, a first-grader who had just got used to studying at school. He spent time learning his nation's language with his friends. However, he learned a different one at home. He may ber confused about the two languages that he is studying. However, if he's extremely focus about his studying, two languages will not be a big problem.
To conclude, I believe that the pros of studying the second language at primary for school for children is much more than the cons. Therefore, the advantages make it worth doing.
