Essay about a foreign language

Some experts believe that it is better for children to begin learning a foreign language at primary school rather than secondary school.
Do the advantages of this outweigh the disadvantages?

There are different opinions regarding the teaching of a foreign language.
On one hand, there are people who consider it right best for children to begin learning a foreign language at primary school.
On the other hand, there are people who think the opposite: they believe that it's better for children to begin learning a foreign language at secondary school. In my opinion, I agree with the first group.
It's important to analyze some points to make a judgment.

Firstly, the greatest speed of children's learning is obvious. Children every day aquire new skills with an astonishing simplicity. In addition we could also talk about the copious number of linguistic's studies about the innate children's ability in the learning of the language. This suggests us that the human's brain has a particular genetic specialization finalized to the language.(I'm not sure what you want to say, but finalized does not make sense here.)

Secondly, we have to say that children have more time to learn. In fact, adolescents and adults have more tasks and less time to devote to learning foreign languages. Furthermore not all people could finish their studies.

To conclude, It's clear that it is better to begin learning a foreign language as soon as possible.
