阅读下面的短文，选择正确答案。

Computers can injure you．Most other injuries happen suddenly．For example，if you fall off a bike and break your arms，it happens very quickly．But computer injuries happen slowly．

You probably know how to ride a bike safely．Now learn to use a computer safely．

Your eyes

Too much light can injure your eyes，so never sit too close to a computer screen．Your eyes should be at least 50 centimeters from the screen．Remember to look away from it sometimes．This gives your eyes a rest．

When you use a computer，the window should be on your left or your right．If it is behind you，the light will reflect on the screen．If the window is in front of you，the sun and the screen will both shine into your eyes．

Your hands and wrists

Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times．If you use a keyboard for a long time，follow these three rules：1）Rest your wrists on something．2）Keep your elbows at the same height as the keyboard．3）Stop sometimes and exercise your hands，wrists and fingers in a different way．

Your back

Some people sit for many hours in front of a computer．If you sit in the wrong way，you can injure your back or your neck．So you should sit with your back straight．The top part of the screen should be in front of your eyes．Your forearms，wrists，hands and the upper part of your legs should all be parallel to the floor．If you are sitting for a long time，get up every 30 minutes and exercise your arms，legs and neck．

Enjoy your computer，but use it safely．

参考译文

计算机会伤害你。其他伤害大多是突然发生的。比如，你从自行车上掉下来摔断了胳膊，它发生得很快。但计算机造成的伤害却是慢性的。

你很可能知道怎样骑自行车才安全。现在，学一下安全使用计算机的方法吧。

你的眼睛

光线太强会伤害眼睛，所以，不要坐得离计算机屏幕太近。你的眼睛至少应该离屏幕50厘米。记住，你应该不时地看看别的地方。这会让你的眼睛得到休息。

当你使用计算机时，窗户应该在你的左边或右边。如果窗户在你后面，光线会反射到屏幕上；如果窗户在你前面，太阳和屏幕都会晃眼。

你的手和手腕

手和手腕可能会受伤，因为手和手腕要在同一个方向上移动数百次。如果你长时间使用键盘，应该遵循下面三个原则：1）把你的手腕放在某样东西上。2）肘部应该和键盘在同一高度。3）不时地停下来朝不同方向活动一下手、手腕和手指。

你的背部

有些人会在计算机前坐许多个小时。如果你坐姿不对，你的背部和颈部就会受到伤害。所以，你坐下时，背部应该挺直。屏幕的上方应该在你眼睛的前方。你的上臂、手腕、手和腿的上部应该与地板平行。如果你要坐很长时间，应该每30分钟起身活动一下胳膊、腿部和颈部。

享受计算机吧，但要注意安全。
