What is the best way to learn a new language? A small study of foreign language learning in adults compared two methods. One is known as the explicit or classroom method. This is the kind of traditional classroom teaching where students are taught a lot of information about grammar rules. The other method is known as the implicit or immersion method. The idea here is to learn much the way children do when they learn a native language, that is, by being with native speakers and absorbing the language that surrounds them, generally without a lot of explanation.
    Teachers may combine these two methods into what Professor Michael Ullman calls immersion-style classroom teaching. But is that necessarily a better way to learn a new language? Mr. Ullman was a senior investigator for the new study. He is a professor of neuroscience at Georgetown University Medical Center in Washington. The 21 adults in the experiment learned Brocanto, a thirteen-word language created for the study. The researchers tested the people for 3 to 6 months after they had learned the language to see how well they could remember it. The study found that those who had learned it with the immersion method had brain waves similar to those of native speakers of a language when speaking that language. Professor Ullman says those who trained with the classroom method also became more native-like in their brain processing. But only the immersion group showed full native-like processing of the grammar.
    Still, he says teachers should be careful how they use the results of his study. And he believes further research is warranted.
    Questions 12 to 15 are based on the passage you have just heard.
    12. What is the characteristic of the explicit method of language learning?
    13. What is the similarity between the implicit method and the way children learn their mother tongue?
    14. What did the subjects of Mr. Ullman’s study learn at the first stage?
    15. In which aspect of the language does the implicit method excel?
