Some people think that the time to begin studying a foreign language is in childhood, and

that the younger you are, the easier it is to learn another language. There is little evidence, however, that children in language classrooms learn foreign languages any better than adults (people over age 15) in similar classroom situations. In fact, adults have many advantages over children: better memories , more efficient ways of organizing information, longer attention spans, better study habits, and greater ability to handle complex mental tasks. Adults are often better motivated than children; they see learning a foreign language as necessary for education or career. In addition, adults are particularly sensitive to correctness of grammar and appropriateness of vocabulary, two factors that receive much attention in most language classrooms.

Age does have some disadvantages, however. For instance, adults usually want to learn a foreign language in a hurry, unlike children, who can devote more time to language mastery. Also, adults have complex communication. Adults need to be able to argue, persuade, express concern, object, explain, and present information about complex matters than are concerning their work or education. Because most adults do not like to appear foolish, they often deny themselves opportunities to practise for fear of making mistakes, not getting their message across, or appearing ridiculously (可笑的) incompetent. Also adults have more trouble than children in making new friends who speak the foreign language.

So the best time to learn a foreign language is when your need is clearest and you have sufficient time. If you are strongly motivated to study a foreign language and if you have enough time to do it, the best time to begin is now.
