In many countries, it was started to set a second language course by schools which from primary schools.In my opinion, however,a foreign language should be taught to children as soon as they stared to get education.It is very hard for an adult to learn a new language when they are getting old. A lot of scientists hold the view that it was the best time to learn different languages when in one's six to twelve years old.One of a friend of mine, who is stared to learn Chinese and English in the same time, is able to use this two language without any problem. Because he use English to communicate with his classmate in school, while using Chinese to talk to his parents. That's the reason why he can handle this two different languages is that he was taught in the same time when he was a baby. However, childen who fail to be taught different languages when they are young,are difficult to learn another language as their mother language.In a long run,children who is learning foreign languages when they are young, may have plenty of time to focus on another works or subjects that they will be taught in high school and university. Then they can full of energy to do other things that they are intersted in.For example, Washinton Briden who is a famous writer,can easily use different languages in his writings, and without thinking how to translation it. However, he knows well about this two different languages as his will,so his books is very well saled. It's attribute to he control two of this languages.Although, children may confused about the usage of two different languages, it can't deny the benifits in different situation in future.To sum up, I take a stand of teaching children a foreign language as soon as they start school. To give them different choices of talk to different people.
