Music lessons may improve memory and learning ability in your children by promoting different patterns of brain development, a study shows．
After a year of musical training, children aged between 4 and 6 performed better at a standard memory test than did children who were not taught music．The findings suggest that music could be useful for building the learning capacity of your minds．
Earlier studies have shown that older children given music lessons become better at IQ tests than those who are musically untrained, but this is the first to show such a benefit in children so young．
Professor Laurek Trainor, of McMaster University in Hamilton, Ontario, also found clear differences in the ways in which children's brains responded to sound after a year of musical training．'This is the first study to show that brain responses in young, musically trained and untrained children change differently over the course of a year," she said．"These changes are likely to be related to the cognitive（ 认知的 ）benefit that is seen with musical training．"
Professor Trainer's team looked at 12 children, 6 of whom had just started extra-curricular （课程外） music lessons and 6 of whom were not being taught any music except that included as a standard part of their school curriculum （课程标准） ．
During the year all 12 children had their brains examined four times using magneto-encephalography （MEG）, and each child was played two types of sound —white noise and a violin tone．The MEG measurements showed that all children responded more to violin sounds than to white noise, reflecting a preferable for meaningful tones, and their response times fell over the course of the year as their brains matured．
64．This passage is mainly about ____．
A．why music lessons are good for the memory
B．the benefit from extra-curricular training for younger children
C．a study on twelve young children's brains
D．new technology to examine children's brains
65．It can be concluded from the text that ____．
A．the study is the first one on the effect of musical training on children's brains
B．scientists got no valuable results from the earlier studies on the topic
C．children musically trained remember things better than those untrained
D．older children get more benefit from musical training than younger ones
66．What do we know about the twelve children tested in the study?
A．None of them had been musically trained before．
B．Only 6 of them had a knowledge of music before．
C．Not all of them had been taught some music in school．
D．All of them were required to learn some music in school．
67．We know from the MEG measurements that ____．
A．the older a child is, the more quickly he/she responds to sounds
B．human brains prefer musical sounds to white noise
C．children of different ages respond to sounds at the same speed
D．all the twelve children like to learn to play the violin very much

Homework can put you in a bad mood (心情), and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children.
The first experiment tested 30 kids. Some shapes (图片) were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes.
In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others.
The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted (使分心) kids from finding shapes.
While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

As many as one in five US teenagers have some degree of hearing loss, according to researchers. They say the problem is growing.
“Teenagers really don’t pay attention to how much noise they are exposed to(接触),” Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even very little hearing loss may influence language development,” said Shargorodsky, one of the researchers.
The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent.
“This certainly is big news,” said Alison Grimes, an ear doctor. “Hearing loss is very common in old people,” Grimes said, but she added that it was worrying to see it happen in the younger age group.
In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could influence learning, said Grimes.
The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure – on the job, at school or from activities, for example – the teenagers didn’t report any change. But Shargorodsky said that might not be true. “We know from before that it is difficult to ask this age group about noise exposure – they underestimate it.” Few people would call it noise when they listen to music on their MP3 player, for example. “There is a difference between what we think is loud and what is harmful to the ear,” said Grimes.
Although it’s not clear that the MP3 players cause teenagers’ hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening.

|
A．to turn the sound down |
