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, Lisa 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 show s 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 Pownall.()36. What will happen if a student sits on a chair all day in school? The student will ________.A. pay more attention to his lessonsB. be funC. like to move aroundD. sit up straighter()37. How long has Dottie Pownall used the balls?A. About three years.B. Only one year.C. In 2008.D. Since he was a fifth-grade teacher.()38.In how many countries are the balls used as the students’ chairs?A. Four.B. Three.C. Two.D. One.()39. Teachers choose balls instead of chairs because sitting on balls helps the kids.A. improve the students’ posture and attentionB. slouch on the chairsC. have funD. Both A and C are correct answers.()40. Which is better for kids to study in class, sitting on a chair or sitting on a ball?A. Siting on a chair.B. Sitting on a ball.C. They are the same.D. We don’t know.B(2011·武汉)Perhaps the only test score that I remember is the 55 when I was in high school.The test was the final for a course. I remember waiting anxiously as my teacher Mr. Right passed out our papers one by one. It was a rather difficult test. I heard my classmates groaning, and I could tell by the groans that the scores weren’t lo oking good.Mr. Right put my paper on my desk. There in big red numbers, circled to draw attention, was my score, 55!I lowered my head, and covered the score up quickly. A 55 is not something that you wanted your classmates to see.“The scores were not very good, none of you passed,” Mr. Right said. “The highest score in the class was a 55.”A 55.That’s me!Suddenly my sad look didn’t look so bad. I had the highest score. I felt a lot better.I walked home alone that day with the low but high score. My father knew that I had a big test that day and asked me as soon as I got home, “How did you do in your test?”“I made a 55,” I said.A frown(皱眉)now stood on my father’s face. I knew I had to explain immediately. “But Dad, I had the highest score in the class,” I proudly stated. I thought that explanation would make a difference.“You failed!” my father replied.“But it’s the highest!” I insisted.“I don’t care what scores others had, but you failed. What matters is what you do!” my father firmly said.For year s, my father was always that way. It didn’t matter what others did. It only mattered what I did and that I did it excellently.We often don’t understand the wisdom(智慧)of good parents until we ourselves stand in the parents’ shoes. My father’s words have ca rried me throughout life.()41. The word groaning is the closest in meaning to ________.A. singingB. laughingC. complainingD. quarreling()42.

A frown stood on my father’s face because he thought ________.A. I did a bad job in the testB. I gave a good excuseC. I became the worst studentD. I stood in his shoes()44. We can infer from the passage that ________.A. the father was strict with his childB. the writer was always poor in testsC. Mr. Right was worried about the writerD. the writer was always happy with his scores()45. Which is the best title of the passage?A. The Final TestB. That’s Me!C. My Strict TeacherD.
