6 . Music is not just a set of sounds and rhythms. Its influence on brain is much deeper than any other human experience. Keep on reading to know all these amazing power of music.

A recent study suggests that preterm (早产的) babies appear to experience less pain and feed more when listening to music. Experts led by Dr. Manoj Kumar of the University of Alberta,Canada,found that music had a beneficial effect on reducing pain for preterm babies experiencing painful medical tests. It also appeared to benefit full-term babies during operations.

Many people experiencing brain damage have speech and movement-related problems. Music can help recover from brain injuries. As a different and effective treatment, doctors often advise such patients to listen to good music to improve the parts of the brain responsible for these two functions. When people with neurological (神经的) disorders hear a musical beat, it helps them to regain a balanced walk.

Though music cannot make deafness disappear, it really can stave off the loss of hearing. There was an experiment involving 163 people where 74 were musicians. Participants were asked to pass some listening tests. Musicians heard the sounds better than non-musicians, and this difference gets clearer with age. This means that a 70-year-old musician hears better than a 50-year-old non-musician, even in a noisy environment.

Besides, music mends a broken heart. It is not about a thrown-away love,   but about a heart attack. The matter is that music can help people recover from a heart attack or heart operation by reducing blood pressure, slowing down the heartbeat rate, and reducing anxiety. Listening to the quality music produces positive emotions, improves the movement of blood, and expands blood vessels, thus, promoting quick recovery of the whole cardiovascular (心血管的) system.

8 . The student arrived early, sat front and center, and stood out in my classroom in more ways than one. I’d say that he was about 40 years older than his classmates in my undergraduate communications class. He eagerly jumped into class discussions, with his humor and wisdom of experience. And he was always respectful of the other students’ perspectives, as if each of them were a teacher. Jerry Valencia walked in with a smile—and he left with one too.

“These students gave me the confidence that I didn’t need to feel bad about my age,” Valencia says.

One day, I spotted Valencia on campus. He said he would have to stop taking classes that semester and reapply for next year. By then, he hoped to have earned enough money and have his student-loan papers in order. He asked seriously whether he could still sit in on my communications class.

Sure, I said. But he wouldn’t get any credit.

No problem, he said.

Soon there he was again, back at his old desk, jumping into our discussions on how to find and tell stories in Los Angeles—a 63-year-old man with as much energy and curiosity as any of the youngsters in class.

A lot of Valencia’s classmates apparently knew he couldn’t afford that semester’s tuition but was still doing the homework. “Here he is, willingly taking a class for the delight of it and benefit of learning,”says Jessica Espinosa, a 25-year-old junior. Afterward, I overheard Valencia wanted to stay in school until he earned a master’s degree, but it had taken him 12 years to finish community college, so he had a long way to go.

There is something splendidly unreasonable about Valencia’s determination to get a four-year degree and then a master’s. At his current pace, he’ll be 90 when he finally hangs all that paper on the wall. But that doesn’t seem especially relevant. He’s found all the youthful energy and academic opportunity stimulating. Valencia’s grade in my class this semester will not show up on his transcripts(成绩单). But I’m giving him an A—and in the most important ways, it counts.

9 . Some students get so nervous before a test. They do poorly even if they know the material. Sian Beilock, a professor at the University of Chicago in Illinois, has studied these highly anxious test-takers. The students start worrying about the results. And when they worry, it actually uses up attention and memory resources (资源).

Professor Beilock and another researcher, Gerardo Ramirez, have developed a possible solution. Just before an exam, highly anxious test-takers spend ten minutes writing about their worries about the test.

The researchers tested the idea on a group of twenty anxious college students. They gave them two short maths tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.

Professor Beilock says those who sat quietly scored an average of 12% worse on the second test. But the students who had written about their fears improved their performance by an average of 5%. Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test. Professor Beilock says highly anxious students who did the writing got an average grade of B+, compared to a B- for those who did not.

“What we showed is that for students who are highly test-anxious, who’d done our writing intervention (干预), all of a sudden there was no relationship between test anxiety and performance. They were performing just as well as their classmates who don’t normally get nervous in these tests.”

But what if students do not have a chance to write about their fears immediately before an exam? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.

10 . Elephant Transit Home

In both Africa and Asia elephants are being threatened by changes in their natural habitats (栖息地). People are moving into the elephants’ habitats and endangering their survival. In the country of Sri Lanka, there is one place where elephants are not only protected but also respected. It is called the Elephant Transit Home (ETH).

Set up in 1995, the ETH aims to protect and nurture baby elephants that are found injured or living without their mothers in the wild. Every year about 30 baby elephants in Sri Lanka need help. As many as possible are brought to the ETH. There they are given food, shelter, and medical care. Most importantly, they are given the chance to be with other elephants and become part of a herd (象群).

A day at the ETH begins early in the morning when the baby elephants are given their first feeding of milk. During the day, each baby will drink an average of 13 gallons of milk. Older elephants are fed mostly coconut leaves and other native plants. Then the elephants are allowed to walk around, eating the grass and forming a herd. The cost of caring for the baby elephants is high. The ETH spends about $125,000 each year on powdered milk for the baby elephants.

At the ETH, workers try to reduce human connection with the elephants. They also try to increase bonds (联系) between the elephants. It usually takes three years for a baby elephant to be set free into its natural habitat. The elephants are sent back to the wild together with other orphans with whom they have bonded. This program helps them return to the wild as members of a herd that will communicate with each other and take care of each other.

The ETH is considered one of the best animal protection sites in the world. Not only are the elephants cared for, they are treated with respect. Most importantly, they go back to live in the wild, where they belong.
