But not Samantha Elton, 15. She seeks them out. And if she can make a fool of herself as in the process, well, that's even better. For the past two years, Elton, has been a practitioner of improvisation, doing things that others would be embarrassed to consider. Elton is a member of High School Jesters, a group that teaches improvisation techniques to students. The group was founded two years ago by Nicholas Kopatich, himself a keen improviser. "I was sitting in my dorm room and some friends were having chats about comedy and improvisation," Kopatich recalls. They asked for lessons after Kopatich told them he had improvisation experience. The small group turned out to be pretty good at it, so they did a show for the dorm. And things snowballed. While even her mother marvels at Elton's ability to get up in front of audience without a script to fall back on, the teen enjoys such opportunities. Performing improvisation comes with a certain freedom that theater doesn't provide. "What I like about it the most is that I don't have to be a certain character or a certain way, and because of that I can't get anything wrong," Elton says, "I get to write the story while I'm doing it." Monica Elton, Samantha's mom, thinks the workshops are a valuable outlet that a lot of students may not get in their schools. High school kids don't usually like to act silly or look uncool, she says, but improvisation teaches them that it's OK to have flaws. "I like to think we give kids positively that allows them to gain confidence," says Brent Mukai, a High School Jesters instructor. The great thing about improvisation is that it is an art form that is open to anyone. But there's more to it than getting up in front of audience and telling jokes or acting silly. "You don't need to be the most amazing actress to be an improviser," Samantha Elton says, "It's really a place where I can show people my creativity. I can paint pictures... Question: What do we know about improvisation? - Performers act as a certain character. - Performers need a script to act on. - Performers intend to make audience embarrassed. - Performers develop the story as they are playing.
Performers develop the story as they are playing.

This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn't want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's manufacturer, recommends 2.5 centimeters. If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion minutes annually - earn $109 billion for the wireless carriers. Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled. Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population. "Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer. Children are more _ to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid . No studies have yet been completed on cell phone radiation and children, she says. Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains. Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen . Question: Why is the warning in the small print? - They think people will not care about it. - There is not enough space for the warning. - They don't want the users to pay attention to it. - The warning is not important at all.
They don't want the users to pay attention to it.

Read the following article and select the best answer. Article: I have some work in Glasgow today. I was on a really tight schedule, which meant I would have no time for myself all day. I was having one of those days, the train was completely packed out and the conversation going on around me seemed to be particularly meaningless. On top of all that, I had a bit a headache. Walking quickly across the hall, I fished some change from my pocket. There was usually someone at the exit selling The Big Issue(a magazine that helps homeless folk earn a living). As the crowd parted ways at the bottom of the hall, I saw someone selling the Big Issue. You had to be homeless to sell the Big Issue. She really looked like she'd been sleeping rough. Her clothes were ragged and she was also rocking from side to side. At first I thought maybe she was trying to keep warm against the biting wind, But she wasn't ,she was moving in time to a tune. I couldn't hear her, but I could see her lips moving. As I got closer, I saw a white cane hanging from her elbow and noticed that she had sunken( ) eyes. She was blind, dirty and living on the streets. I came closer and through the noise of the traffic I heard her sing the immortal line, "--and I think to myself, what a wonderful world!" I bought her last magazine for twice what I'd originally intended. She thanked me, then she picked up her stuff and went tapping off along the pavement--still singing! So, I have my happy memory for the day. And I think it will stay with me a long ,long time. Feel free to borrow it if you like. Question: Why do some actors keep a sad thought or memory according to the passage? - Because some of them always feel unhappy. - Because they are scolded by the director. - Because it helps them meet the needs of their roles. - Because they can't find a happy memory.
