资料：What if you were told there was a way you may strengthen your cognitive skills and heighten your intelligence, and all you had to do was was learn to strike up basic conversations in another language?
It probably sounds great, because if you’re like most you would love to be able to speak a second language. But then, you recall your experience in high school foreign language-boring tote memorization and long hours with little progress-and perhaps it doesn’t sound so good any more.
But, what if you were told it would take only 10 days to be on your way to becoming bilingual? Most people recognize the many benefits of learning a foreign language: You can travel to foreign countries and fell comfortable, be a more productive and enticing employee in today’s competitive job market, and immerse yourself in the vast cultures that surround you.
But now, the collective evidence from a number of recent studies suggests that the bilingual experience improves the brain’s so-called executive function-a command system that directs the attention processes that we use for planning, solving problems, and performing various other mentally demanding tasks.
These processes include the ability to ignore distractions to stay focused, switching attention willfully from one thing to another, and holding information in the mind-like remembering a sequence of directions while driving.
Even better, new approaches to learning mean you can learn a new language without the endless repetition, homework, and memorization. One of the most powerful actually trains people to start speaking a new language in as little as 10 days! In fact, it’s so powerful, even the FBI has purchased it!
