[EX Q]: Article: The first Ml choir rehearsal of the school year took place in the school hall. All the students joined together to sing. I watched as my elder sister and her grade came in and took their places next to us on the stage. Meanwhile, I could hear laughing. Some students were pointing at a girl standing next to my sister. I'd never seen this girl before. A girl whispered in my ear, " Did you know she's wearing diapers ?" After school that evening, I asked my sister about the girl I'd seen. She told me her name was Theresa and that she was a very nice girL ." Why were those kids being mean to her? I asked, "Because they're stupid," she said. One day, I was walking home from school when I heard voices behind me. "There's the little idiot's sister. Does your sister wet her pants too?" I walked a little faster and then I felt a atone hit me in the back. When I got home, I ran down to my sister's room. I pushed my way into her room, screaming at her. "Why do you have to be that giri's friend? I don't see anyone else being nice to her, " Janelle yelled back, Because she is a wonderful person and she is dying!" I will remember those words as long as I live. Theresa wet her pants because she had an illness, which was killing her. My sister was the only one nice enough to be her friend and stick up for her. A few months later, Hieresa passed away. I felt proud that Janelle was my sister. Throughout the years I watched her, and she always made friends with everyone. It didn't matter if they ware fat, thin, brilliant or not. She never left anyone feeling isolated or alone. It was she who changed me and taught me to never look at anyone in the same way again.

[EX Q]: Article: What would you think if you went back to school on Monday and there were no desks or chairs in your classroom? That's what some fourth-and-fifth-graders at a school in Minnesota discovered earlier this year when they took part in a research project to see if changing their classrooms would make them more active. Researchers from the Mayo Clinic were concerned about reports that as many as half of American kids could be seriously overweight - or obese - by the year 2014. So they set up a different kind of classroom, which you might see in the future. Instead of desks, the Elton Hills Elementary students had adjustable work stations where they could stand, kneel on mats or sit on big exercise balls. Students were given laptops and iPods that allowed them to move and learn at the same time. Sensors were attached to the kids' legs to calculate how many calories students burned in their new set-up. Their typical school day was probably not anything like yours. One group of students downloaded an audio file of their teacher reading a book; they listened to it while walking for exercise. Another group took a spelling test by listening to their iPods. Some students liked the freedom, but others missed the traditional classroom. "I don't like standing up," Mariah Matrious said. "My legs get tired, and I like sitting down. " So, did the experiment work? Researchers still are studying the data, but early results indicate that the kids did move around more in the new classroom. "It showed us that, given the opportunity to move, kids will move," said researcher Lorraine Lanningham-Foster. That's important because studies have shown that even simple movement - climbing stairs instead of taking an elevator , for example, or washing dishes by hand instead of loading the dishwasher - can be as important as formal exercise when it comes to controlling one's weight.
