reaction for language learner

In these days,we study in new unit (language learner) which discuss about what kinds of characteristics will affect success when we learn second language. Among a series of factors,most interesting for me is age which people start to learn second language at . In the context, there are two controversial issue. One side of resaerchers believe that if people start to study language at young age are faster than others who learn in older age. On the other hand,the others support adults are more likely to be successful.In my opinion, I agree the first theory for learning language.
First of all, younger people have better memory for experience new incident which means they are able to learn new language quickly. Secondly, compared to teenagers or adults ,children are less embrassed in making a mistake. They always try to speak out what they want to impress without anxiety. Therefore, they have more opportunities to practice repeatedly. In my personal experience, i can feel obviously that my ability of memory is getting worse than when i was high school. Therefore, i hope i had studied English well when i was child.
