    Sitting on exercise balls brings more than a smile to students and teachers.
    Some fourth-graders at Conrad Weiser West Elementary School in Womelsdorf love their new chairs-—probably because they're not really chairs at all.
    The kids are sitting on the air-filled balls. But different from those just for exercise, these have small legs that keep them from rolling. 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 using exercise balls instead of common chairs, teachers find students' posture(姿势) and attention improved.
    Dotti Pownall, a fifth-grader teacher in West Virginia, 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 percent, thought sitting on the balls helped them concentrate(专注) better:
    "Besides, they’re fun,b" says Pownall.
    According to WittFitt,b a company that has sold balls to more than 200 schools, they can improve kids' posture and classroom behavior.
    Exercise ball chairs are getting popular in classrooms, from preschool to college. Some adults (成人) even use them at work.
    Lisa Witt felt so strongly about the use of balls as chairs that she started WittFitt. She said the company not only encourages the use of balls but also educates teachers and students on how to use them. "We sell balls in 24 states in America, three provinces in Canada and Japan." says Witt.
    小题1:Sitting on exercise balls can______.
    A．improve students' attentionB．make students smarter
    C．keep students moving around D．help students become fit
    小题2:According to the passage, the company WittFitt______.
    A．began to produce balls in 2008 B．sells balls in 24 countries
    C．was set up by Lisa WittD．is famous around the world
    小题3:It can be seen from the passage that ______.
    A．exercise balls have no legsB．Pownall works as a teacher
    C．students hate exercise balls D．exercise balls are filled with sand
    小题4:The passage mainly tells us about______.
    A．the shape of exercise balls B．the use of exercise balls
    C．the number of exercise balls D．the inventor of exercise balls

    Want to save the environment? You probably can’t fix everything on your own, but by taking small steps and keeping the environment in mind every day, you can make a difference,
    1. Think Green. Challenge yourself to think about the environment as you live your life. If you shut off lights when you leave the room, turn off your TV when you’re not watching it, you’ll save energy. If you take shorter showers, you’ll save water.
    2. Shop Green. Shopping is fun, but buying things you don’t need is wasteful and bad for the earth. Before you buy something, ask yourself how much you’ll really use it. Keep yourself away from buying products with unnecessary packaging (包装), and whenever possible, buy things that were locally made instead of those shipped from far away.
    3. Dress Green. Wear green trousers and T-shirts if you want. But what really matters isn’t the colour, it’s how the clothes were made. If you want to help the environment, the best place to find clothes is at a vintage store, but you might not want to buy everything used. No matter where you shop, keep an eye out for products made from environmentally friendly materials like organic(有机的) cotton, which is grown without the use of pesticides ( 杀虫剂).
    4. Study Green. What’s better than learning about the environment? Save it while you learn, It can be as simple as using both sides of a piece of paper before you recycle it, or reusing an old textbook :instead of buying a new one. If you want to do more, join an environmental group at your school, and encourage your friends to join, too.
    小题1:The underlined phrase "a vintage store" in this passage refers to (是指) a place where you can buy          .
    A．cheap clothesB．fashionable clothes
    C．second-hand clothesD．clothes of special size
    小题2: Which of the following acts does not agree with the writer’s green ideas?
    A．Taking shorter showers.
    B．Buying products with unnecessary packaging.
    C．Wearing clothes made from organic materials.
    D．Using both sides of a piece of paw.
    小题3: What does the passage mainly talk about?
    A．Some Methods to Live Happily.B．Some Advice to Save Money in Daily Life.
    C．Some Steps to Live a Healthy Life.D．Some Ways to Make One’s Life Green.

    If you want to become a better reader, what should you know about speed of reading?
    Some people read very rapidly(很快地), while others read very slowly. But which one is
    better?
    The rapid reader may be a good reader when he reads a storybook for fun. But he may not be
    able to slow down enough to read directions(说明) carefully. He may read so rapidly that he does
    not take time to understand fully the ideas and information which are important to remember.
    The slow reader may be a good reader when he reads directions for making something. But he
    may spend too much time in reading a simple story which is meant to be enjoyed but is not
    important enough to be remembered.
    So, you see, either a rapid reader or a slow reader is not really a good one. If you wish to
    become a better reader, here are four important things to remember about speed of reading.
    1. Knowing why you are reading will often help you to know whether to read rapidly or
    slowly.
    2. Some things should be read slowly throughout. Examples are directions for making or doing
    something, science and history books, and Maths problems. You must read such things slowly or
    remember each important step and understand each important idea.
    3. Some things should be read rapidly throughout. Examples are simple stories for enjoyment,
    letters from friends and bits of news from hometown papers.
    4. In some of your reading, you must change your speed from fast to slow and slow to fast, as
    you go along. You will need to read certain(某些) pages rapidly and then slow down and do more
    careful reading when you come to important ideas.
    小题1: What should be read rapidly?
    A．Directions for making something.
    B．Maths problems.
    C．Science and history books.
    D．Storybooks, newspapers, personal letters, etc.

    Expert(专家) say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger (手指) with his eyes still closed, begging(请求) for one more minute to sleep. Like thousands of students “early birds” in China, he has to get up before six every morning.
    A report shows that without a good night’s sleep, students seem to be weaker (虚弱) than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.
    Experts have ever said that the students should develop good study habits. So some clever students never study last, they are able to work well in class.
