题目内容

Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs, teachers find students' posture (姿势) and attention improve.
Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning.
The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico ('波多黎各) and Japan," says Witt. "Research shows that sitting on the balls makes them sit up straighter. You can slouch (低头垂肩地坐) on a ball," says Witt, "but it feels awful." Because the students are moving, their blood (血液) increases. That carries more oxygen (氧气 to the brain (大脑), so the kids have more energy and can focus longer.
"Furthermore, they're fun." says Pownali.

I remember the first time I met Alfred after years. He was sitting on a bench in the park. He looked very sad and cold. He hadn’t got a coat on and it started to rain. Usually, I don’t like to stop to speak to a stranger who looked like that. His shoes were well-cleaned and his clothes were quite smart, but he did not have an umbrella with him and he was getting wet in the rain. I stopped walking and said to him in a nice voice. “ Are you OK?” he looked up, and was surprised to see me. He cried out. “ Are you …” he couldn’t remember my name. I was also surprised. He was Alfred! “ I’m Tom, Alfred, what are you doing here?” I asked. He did not explain to me, but caught my hand, and asked how my life was like. I told him that I was out of job. I suggested that we go somewhere warm and dry.
So we found a café nearby and continued our conversation. I learned that he married with two children, and his wife was Sherry. I could not believe my ears. Twenty years ago his best friend was Linda, and Sherry was his worst enemy! They often had quarrels ( 争吵) and fights in the play.
Alfred told me that he became a businessman when he graduated from the school and owned two companies in the city. I asked him why he was sitting in the rain in the park. He said that he had just had a quarrel with Sherry, and acting in the same way as when she was young, threw him out of the door and locked him　out. He was young, threw him out of the door and locked him out. He was waiting for her to be calm and let him in again.
