When you think of all the ways your body can get hurt---falling off a bike, stepping on a nail, being bitten by a crazed dog---the aches and pains that come from sitting at a computer may not seem like much.
But more doctors are getting worried about just that. If you sit at a PC the wrong way, the nerves and muscles in your back, neck and arms can get out of line.
Ergonomics is the study of how people work and how jobs and equipment can be designed so that people are safer and more comfortable in the things they do---whether that’s working on a factory assembly line or sitting in front of a computer.
The monitor
You should not have to tilt(傾斜) your neck up or down to lock at the screen. Your eyes should be level with the top of the screen.
How far away should you sit? Reach your arm out so your fingertips just touch the screen.
The keyboard
It should be directly in front of you. Don’t unfold the legs on the bottom of the keyboard so that it tilts up toward you---it should be as flat as possible, or even tilted away from you. You want your wrists “neutral,” which means straight, not bent. This puts less strain on your nerves and muscles.
Arms should be close to the body. Don’t look at your fingers as you type. Use a document holder to hold papers at the same level as the monitor. Keep the mouse on the same level as the keyboard and close by--- so you don’t have to reach for it.
The chair
Your feet shouldn’t dangle---the blood will pool in your feet. They should rest flat on the floor, or on phone books, if necessary. Your back needs support. Roll up a towel and stick it there.
The Body
If you think of your body as a collection of right angles when you sit at a computer, you should be just fine.
Your hips should be at a 90-degree angle to your back. That takes the pressure off the spine. And your knees should bend at a 90 degree angle so your feet are flat.
【小題1】The passage mainly talks about        .

A.a(chǎn)voiding pains caused by using PCB.the science of ergonomics
C.illness caused by a computerD.how to keep fit
【小題2】The underlined word “ergonomics” most probably means ______ in Chinese.  
A.管理學(xué)B.人機工程學(xué)C.機械工程學(xué)D.經(jīng)濟學(xué)
【小題3】How high should a monitor be placed according to the passage?
A.As high as your arms.
B.A little higher than your eyes.
C.A little lower than your eyes.
D.At the same level as your eyes.
【小題4】How shouldn’t a keyboard be placed?
A.Tilting away from you.B.Tilting up toward you.
C.Flat.D.Not mentioned.
【小題5】How should you place your foot?
A.Rest them on a phone book.B.Rest them on the floor.
C.They should rest flat.D.They should dangle.


【小題1】A
【小題2】B
【小題3】D
【小題4】B
【小題5】C

When you are little,the whole world feels like a big playground.I was living in Conyers,Georgia the summer it all happened.I was a second grader,but my best friend Stephanie was only in the first grade.Both of our parents were at work and most of the time they let us go our own way.

It was a hot afternoon and we decided to have an adventure in Stephanie's basement.As I opened the basement door,before us lay the biggest room,full of amazing things like guns,dolls,and old clothes.I ran downstairs,and spotted a red steel can.It was paint.I looked beyond it and there lay even more paint in bright colors like purple,orange,blue and green.

“Stephanie,I just found us a project for the day.Get some paintbrushes.We are fixing to paint.”She screamed with excitement as I told her of my secret plans and immediately we got to work.We gathered all the brushes we could find and moved all of our materials to my yard.There on the road in front of my house,we painted big stripes(條紋)of colors across the pavement(人行道).Stripe by stripe,our colors turned into a beautiful rainbow.It was fantastic!

The sun was starting to sink.I saw a car in the distance and jumped up as I recognized the car.It was my mother.I couldn't wait to show her my masterpiece.The car pulled slowly into the driveway and from the look on my mother's face,I could tell that I was in deep trouble.

My mother shut the car door and walked towards me.Her eyes glaring,she shouted,“What in the world were you thinking?I understood when you made castles out of leaves,and climbed the neighbors' trees,but this!Come inside right now!”I stood there glaring back at her for a minute,angry because she had insulted(侮辱)my art.

“Now go clean it up!”Mother and I began cleaning the road.Tears ran down my cheeks as I saw my beautiful rainbow turn into black cement.

Though years have now passed,I still wonder where my rainbow has gone.I wonder if,maybe when I get older,I can find my rainbow and never have to brush it away.I guess we all need some sort of rainbow to brighten our lives from time to time and to keep our hopes and dreams colorful.

56.What did the writer want to do when his mother came home?
