Studies have documented that smiling is a universal and effective way to lift mood. But in the latest research on the power of the smile, researchers led by Marcus Munafo of the University of Bristol in England found that even seeing smiles on the faces of others can have a profound effect on a person's tendency toward violence or aggression -- that is, as long as that person recognizes the smile as one of happiness, and not as a sneer . Munafo and his colleagues conducted a series of experiments involving normal adults and highly aggressive teens referred to a youth program, either by educational authorities or the courts. About 70% of the teens already had a criminal record. In the first experiment, 40 healthy adults, aged 1830, looked at facial expressions on the computer ranging from happy to angry with increasingly difficult ones to _ in between. Participants were asked how angry they felt and then had to rate the images as displaying either happiness or anger -- there was no option for "unclear" or "unable to tell". From these ratings, the scientists could generate a score of their preference toward happiness or anger. Previous research found that aggressive people -- including violent offenders -- tend to consider even a common expression as an unfriendly one. "You looking at me?" can easily turn a simple question into a tragic fight. Based on their original scores, half of the participants were then told by the computer that some of the unclear faces that they had rated as angry should have been scored as happy. This was intended to guide them toward judging the inbetween faces more positively. The other 20 received feedback that simply proved their first choices, creating a control group. After this training, both groups were tested again and the group that received the biased feedback shifted its ratings of unclear faces toward the happy side. Participants were also asked to rate their level of angry feelings again after completing the second round of testing. Those who were trained to consider... According to Munafo's research, the anger and violent behavior in some youths resulted from _ . A) their misunderstanding of facial emotions of others B) their lack in knowledge of emotion recognition C) their inborn tendency toward violence or aggression D) their experience of being offended by others on purpose

Before Christmas, We had a really big fight, and Jamie and Jenna were against me, both saying I was bossy . I felt helpless and lonely. I thought Christmas would be horrible! _ "Wow," I said, breaking the silence as we stood on either side of my front door. "Thanks." "Okay...well... I have to go," she said softly. "Okay. See you later then..." and I closed the door. "Who was that at the door?" my mom asked. "It was Jenna, my classmate." I said.

Besides, we said we were going to be friends even when we're eighty-two." I stopped reading and started laughing. I couldn't believe I had forgotten what she said that day in the backyard.

At the onset of a northern winter, many dream of warmer climates.In 1934 the Canadian-born composer Colin Mcphee did more than dream. He set out for the island of Bali. In his bookA House in Bali,Colin Mcphee described how he first gained insight into the essence of Balinese music.For about a month he had been working on transcribing a complete score to a Balinese play he had seen. It seemed impossible that so much beauty could be achieved with a scale of only five tones. But the distinctive embellishments of the music _ him.Fortunately a young household helper and his friend decided to assist. One morning they set two objects next to Mcphee's piano.They were gangas--metal keyed instruments.The two boys played them in what struck Mcphee as"a fast duet in Morse code". At last the composer had found the key to Balinese music."Wait!" Mcphee would call out from the piano as the boys flew along,"Stop!Please!That bit once more!" Patiently the boys would stop and began again.But soon they were flying again,faster than ever, amazing Mcphee with their memory and precision. Sometimes the patterns repeated.Sometimes they opened up into something new. Then, suddenly the whole duet would fly apart and the boys would burst out laughing,breaking the spell. Although Colin Mcphee left the island in 1939,he remained spellbound by Balinese music.And its rich,distinctive sound would colour many of the compositions he would write for the next quarter century. From the passage we can learn that _ . A) Colin Mcphee set foot on the island of Bali in late winter B) The book A House in Bali detailed how Colin Mcphee understood the life of the island C) Colin Mcphee actually acquired much beauty of Balinese music D) For a month Colin Mcphee had been watching a Balinese play he had seen before
