Learning a new language is hard． In recent research， scientists found that your

chances of reaching fluency（流利） in a new language drop off at the age of 10． Does that mean you should give up your French class if you are older than 10？ No!

    The research found that it's "nearly impossible" to reach fluency if you start learning a language after age 10． That's not because your language sills start to get worse． "You're still learning fast，" says Joshua． "It's just because your ability to learn starts dropping at around 10 or 11 years old．"

    The researchers say people who try to learn a new language after 10 may still become quite good． But they will probably not become fluent． Kids may better than adults at learning new languages for many reasons． One is that children's brains are more adaptable（能适应的） than adults' brains． This means they are better able to change． Kids may also would like to try new things． And adults may depend on the rules of their first language． But kids are able to accept a new language without them．
