高一英语单项填空简单题查看答案及解析

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（倾斜） 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.

1.The passage mainly talks about________.

A．avoiding pains caused by using PC           B．the science of ergonomics

C．illness caused by a computer               D．how to keep fit

2.The underlined word “ergonomics” most probably means ______ in Chinese.

A．管理学           B．人机工程学        C．机械工程学        D．经济学

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.

4.How shouldn’t a keyboard be placed?

A．Tilting away from you.                    B．Tilting up toward you.

C．Flat.                                  D．Not mentioned.

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.

“When can I get a cell phone?” The answer is when your parents think you need one, though many kids seem to be getting them around age 12 or 13. Some younger kids may have them because their parents see it as a matter of safety and convenience. For example, a kid can call mom and dad when sports practice is over. And a cell phone can give kids almost instant access(快捷通道) to their parents if something goes wrong or they need help. It can give parents quick access to their kids so they can check on them and make sure they’re OK.

If you do get a cell phone, make some rules with your parents, such as how many minutes you’re allowed to spend on the phone, when you can use your phone, when the phone must be turned off, and what you will do if someone calls you too often, and so on.

You’ll also have to learn to take care of the phone in your life. Keep it charged(充电) and store it in the safe place so it doesn’t get lost. And whatever you do, don’t use it in the bathroom. I know someone who dropped her phone in the toilet!
