Scientists are particularly interested in the brains of people who speak more than one language【C1】flu______ because that skill is hard to acquire after about age seven. In one of Kuhl’s studies, for example, native Mandarin Chinese speakers spoke Chinese to nine-month-old American babies for twelve sessions over four weeks. Each【C2】______lasted about 25 minutes. At the end of the study, the American babies【C3】res______to Mandarin sounds just as well as Chinese babies.
If a child【C4】reg______hears two languages, their brain forms a different pathway for each language. 【C5】How______, once the brain solidifies those electrical language pathways by around age seven, it gets harder to form new ones. By then, a baby’s brain has disposed of, or pruned, all the【C6】______(necessity) connections that the infant was born with. So, if you don’t start learning Spanish or Russian until middle school, you must struggle against years of brain development, and progress can be frustrating. A twelve-year-old’s brain has to work much harder to forget language connections than an infant’s brain does. "We ought to be learning new languages【C7】______ages zero and seven, when the brain does it naturally," Kuhl says.
For teenagers and adults who want to learn new languages, baby studies may offer some useful tips. For one thing, researchers have found that it is far better for a language learner to talk with people who speak the language than to rely on【C8】______ (educate) CDs and DVDs with recorded conversations. When infants watched someone speaking a foreign language on TV, Kuhl found, they had a completely different【C9】exp______than they did if they watched the same speaker in real life. With real speakers, the babies’ brains lit up with electrical activity when they heard the sounds they had learned. "The babies were looking at the TV, and they seemed mesmerized," Kuhl says. Learning, on the other hand, did not【C10】hap______. "There was nothing going on in their brains," she says. "Absolutely nothing. " [br] 【C6】
