A、Singing could lead to new ways of learning a foreign language. B、Teachers shouldn’t use music all the time to teach language.

Now listen to the following recording and answer questions 23 to 25.
    Have you ever found yourself in this situation: You hear a song you used to sing when you were a child — a bit of nostalgia. But it is not a distant childhood memory. The words come back to you as clearly as when you sang them all those years ago. It seems there is a scientific reason for this.(23)Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most difficult languages. Here is what they did. Researchers took 60 adults and randomly split them into three groups of 20. Then they gave the groups three different types of listen-and-repeat learning conditions. Researchers had one group simply speak the words. They had the second group speak the words to a rhythm, or beat. And they asked the third group to sing the words. All three groups studied words from the Hungarian language for 15 minutes. Then they took part in a series of language tests to see what they remembered.(24)After the tests were over, the singers came out on top. The people who learned these new Hungarian words by singing them showed a higher overall performance. They did the best in four out of five of the tests. They also performed two times better than those who simply learned the words by speaking them.(25)Dr. Katie Overy supervised the study at the university’s Reid School of Music. She said singing could lead to new ways of learning a foreign language. The brain, it seems, likes to remember things when they are contained in a catchy, or memorable, tune. Language teachers already know the value of using music and singing. A teacher at a Chinese language school in Washington, D. C. relies heavily on songs and chants to teach Chinese. Hua ZhuYing teaches students who most likely have never spoken Chinese before coming to the school. Ms. Hua says she uses music all the time to teach children Chinese. She adds that not only does it work, but it is fun for the kids.
