[Q]: Article: Once I invited a group of friends round to my house, telling them that I was going to record their speech. I said I was interested in their regional accents, and that it would take only a few minutes. Thus, on one evening, three people turned up at my house and were shown into my front room. When they saw the room they were a bit alarmed, for it was laid out as a studio. In front of each easy chair there was a microphone at head height, with wires leading to a tape-recorder in the middle of the floor. I explained that all I wanted was for them to count from one to twenty. Then we could relax and have a drink. I turned on the tape-recorder and each in turn seriously counted from one to twenty in their best accent. When it was over, I turned the tape-recorder off and brought round the drinks, and for the rest of the evening there was general cheerful conversation--interrupted only by the fact that I had to take a telephone call in another room, which unfortunately lasted some time. Or at least that was how it would appear. For, of course, the microphones were not connected to the tape-recorder in the middle of the room at all but to another one, which was turning happily away in the kitchen. The participants, having seen the visible tape-recorder turned off, paid no more attention to the microphones which stayed in front of their chairs, only a few inches from their mouths, thus giving excellent sound quality. And my lengthy absence meant that I was able to obtain as natural a piece of conversation as it would be possible to find. I should add, perhaps, that I did tell my friends what had happened to them, after the event was over, and gave them the choice of destroying the tape. None of them wanted to--though for some years afterwards it always seemed to be my round when it came to the buying of drinks. Linguistic research can be a very expensive business.

[Q]: Article: As a music teacher for twenty-seven years, I have always known that music touches the soul. It can break through all kinds of barriers to reach students in a very special way. It can be the means for each child to find their light. A few years ago, I was blessed with the opportunity to teach pre-school students one afternoon a week. One of my most memorable students was Vanessa. She was five years old, had difficulty walking, and could not speak. We mostly sat on the floor for our music lessons and Vanessa liked to sit on my lap. One of her favorite songs was John the Rabbit. It was a call and response song where I sang the call and the students clapped two times while singing the repeating phrase, "Oh, yes!" Vanessa liked to put her hands together with mine and clap with me. We performed that song during every class, Vanessa and I clapping together. She never said or sang a word. One day late in the school year, when the song was finished, Vanessa turned around, looked me in the eye, clapped her tiny hands two times and said the words "Oh, yes!" I opened my mouth and could not speak. Through music, we had made a connection. Several years later, I came across Vanessa on the street in town. I stopped my car and waved to say hello. She waved back with a big smile on her face and then clapped her hands two times, mimicking the song we had performed in our music class. This precious little girl, through her connection with music, left an impression on me that will last forever. Every child has the ability to learn and grow. It is up to us educators to discover the way to reach each and every one of our students. We all must find each child's light.
Question: The author thinks music _ .
Options: (A) can make children calm down (B) Can connect heart to heart (C) Is difficult for pre-school students (D) Is a good means to find a job

[Q]: Article: A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults.But the extent to how much TV may be to blame is a question that the study leaves unanswered. The researchers used a national long-term survey of adolescent health to look into the relationship between media use and depression.They based their findings on more than 4,000 adolescents who were not depressed when the survey began in 1995. As part of the survey, the young people were asked how many hours of television or videos they watched daily.They were also asked how often they played computer games and listened to the radio. Media use totaled an average of 5 and one half hours a day.More than 2 hours of that was spent watching TV. 7 years later, in 2002, more than 7 percent of the young people had signs of depression.The average age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author of the new study.He says every extra hour of television meant an 8 percent increase in the chances of developing signs of depression. The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio.But the study did find that young men were more likely than young women to develop depression given the same amount of media use. Doctor Primack says the study did not explore why watching TV causes depression.But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and socializing. It might also affect sleep, he says, and that could have an influence. The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives.Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people.The study found that happy people are more likely to be socially active, to read, attend community services and to vote.
Question: More than 4,000 adolescents were chosen as the subjects of the study because they _ .
Options: (A) were free from depression (B) were fond of using the media (C) attached much importance to their health (D) could afford the time for the long-term survey
