Learning to play a musical instrument can change your brain, with a US review finding musical training can lead to improved speech and foreign language skills. Although it was suggested in the past that listening to Mozart's music or other classical music could make you smarter, there has been little evidence to show that music can boost  brain power. But a data-driven review by Northwestern University has pulled reaserch together that links musical training to learning that spills over into   skills including language, speech, memory, attention and even vocal emotion. Researcher Nina Kraus said the data strongly suggested that the nervous connections made during musical training also prepared the brain for other aspects of human communication. " The effect of musical training suggests that, like physical exercise and its effect on body fitness, music is a resource that tones the brain for _ fitness and thus requires society to re-examine the role of music in shaping individual development, " the researchers said in their study. Kraus said learning musical sounds could improve the brain's ability to adapt and change and also enable the nervous system to provide constructing patterns that are important to learning. The study, published in Nature Review Neuroscience , looked at the explosion of research in recent years focusing on the effect of musical training on the nervous system which could have impacts for education. The study found that playing an instrument prepares the brain to choose what is related in a complex process that may involve reading or remembering a score, timing issues and coordination with other musicians. What is the text mainly about ? A) The effect of physical exercise. B) The researcher named Kraus. C) The benefit of musical training. D) Musicians' improved skills.

Freda Bright says,  _ ." It's true.You really can't love somebody to death.I've known people to die from no love, but I've never known anyone to be loved to death.We just can't love one another enough. A heart-warming story tells of a woman who finally decided to ask her boss for a raise in salary.All day she felt nervous and late in the afternoon she summoned the courage to approach her employer.To her delight, the boss agreed to a raise.                                                 The woman arrived home that evening to a beautiful table set with their best dishes.Candles were softly glowing.Her husband had come home early and prepared a festive meal.She wondered if someone from the office had tipped him off, or...did he just somehow know that she would not get turned down?  She found him in the kitchen and told him the good news.They embraced and kissed, then sat down to the wonderful meal.Next to her plate the woman found a beautifully lettered note.It read: "Congratulations, darling! I knew you'd get the raise! These things will tell you how much I love you."  Following the supper, her husband went into the kitchen to clean up.She noticed that a second card had fallen from his pocket.Picking it off the floor, she read: "Don't worry about not getting the raise! You deserve it anyway! These things will tell you how much I love you."  Someone has said that the measure of love is when you love without measure.What this man feels for his wife is total acceptance and love, whether she succeeds or fails.His love celebrates her victories and soothes her wounds.He stands with her, no matter what life throws in their direction. Upon receiving the Nobel Peace Prize, Mother Teresa said: "What can you do to promote world peace? Go home and love your family." And love your friends.Love them without measure.

Of all the components of a good night's sleep, dreams seem to be last within our control. In dreams, a window opens into a world where there is zero logic and dead people can speak. A century ago, Freud formulated  his revolutionary theory that dreams were the hidden shadows of our unconscious desires and fears; by the late 1970s, neurologists  had switched to thinking of them as just "mental noise"--the random byproducts  of the neural repair work that goes on during sleep. Now researchers suspect that dreams are regulating moods while the brain is "offline". And one leading authority says that these intensely powerful mental events actually can be bought under conscious control, to help us sleep and feel better. "It's your dream," says Rosalind Cartwright, chair of psychology at Chicago's Medical Center. "If you don't like it, change it." Evidence from brain imaging supports this view. The brain is as active during rapid eye movement sleep when most vivid dreams occur as it is when fully awake, says Dr. Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved: the limbic system or the emotional brain is especially active, while the prefrontal cortex--the center of intellect and reasoning, is relatively quiet. "We wake up from dreams happy or depressed, and those feelings can stay with us all day," says Stanford sleep researcher Dr. William Dement. This link is shown among the patients in Cartwright's clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don't always think about the emotional significance of the day's events--until, it appears, we begin to dream. There is probably little reason to pay attention to our dreams at all unless they keep us from sleeping or "We wake up in a panic," Cartwright says. Those suffering from persistent nightmares should... Casual nightmare sufferers are advised to  _  . A) ask for medical help B) relax their mind during the day C) don't take the dreams seriously D) realize the emotional significance of daily events

Whether you admit it or not, music improves our daily life and makes us feel easy, especially the music of Beethoven and Mozart. But can you believe that a school in England is using classical music to cut down students' bad behavior? The head teacher Brian Walker at the West Park School in Derby asks some students to stay behind after school on Fridays. He forces his students to listen to Mozart and other classical music. He also makes them copy his favorite poems and they have to watch educational videos. Mr. Walker says his main aim is to stop noisy pupils causing trouble in class for students who want to study. He said the students staying behind were "not the smokers or drinkers, the truants   or the people who are late for school...It's those who have slowed the learning and teaching in class for everyone". Mr. Walker said this was unacceptable, because it was making the rest of the students fail to focus their attention on their study. Mr. Walker believes what he does reminds students that education is something to value. "It helps them see they are part of something bigger that will improve their life chances," he said. The head teacher thinks students in fact learn from being kept behind after school. "Hopefully, I open their ears to an experience they don't normally have and don't want to have again, so it's both educational and acts as a warning." Music has had success elsewhere in reducing bad behavior. In 2004, it reduced crime on London's subway by 25 percent. Researchers from a Belfast university found it helped stop elephants' bad behavior. However, one West Park student called Kieran said, "An hour of Mr. Walker's music is a real killer." Why does Mr. Walker say some students' bad behavior is unacceptable? A) Because the rest of the students hate them. B) Because they are wasting their life. C) Because they are disturbing teachers. D) Because they have a bad influence on the other students.
