閱讀下面的短文，選擇正確答案。

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．

參考譯文

計(jì)算機(jī)會(huì)傷害你。其他傷害大多是突然發(fā)生的。比如，你從自行車上掉下來摔斷了胳膊，它發(fā)生得很快。但計(jì)算機(jī)造成的傷害卻是慢性的。

你很可能知道怎樣騎自行車才安全?，F(xiàn)在，學(xué)一下安全使用計(jì)算機(jī)的方法吧。

你的眼睛

光線太強(qiáng)會(huì)傷害眼睛，所以，不要坐得離計(jì)算機(jī)屏幕太近。你的眼睛至少應(yīng)該離屏幕50厘米。記住，你應(yīng)該不時(shí)地看看別的地方。這會(huì)讓你的眼睛得到休息。

當(dāng)你使用計(jì)算機(jī)時(shí)，窗戶應(yīng)該在你的左邊或右邊。如果窗戶在你后面，光線會(huì)反射到屏幕上；如果窗戶在你前面，太陽和屏幕都會(huì)晃眼。

你的手和手腕

手和手腕可能會(huì)受傷，因?yàn)槭趾褪滞笠谕粋€(gè)方向上移動(dòng)數(shù)百次。如果你長(zhǎng)時(shí)間使用鍵盤，應(yīng)該遵循下面三個(gè)原則：1）把你的手腕放在某樣?xùn)|西上。2）肘部應(yīng)該和鍵盤在同一高度。3）不時(shí)地停下來朝不同方向活動(dòng)一下手、手腕和手指。

你的背部

有些人會(huì)在計(jì)算機(jī)前坐許多個(gè)小時(shí)。如果你坐姿不對(duì)，你的背部和頸部就會(huì)受到傷害。所以，你坐下時(shí)，背部應(yīng)該挺直。屏幕的上方應(yīng)該在你眼睛的前方。你的上臂、手腕、手和腿的上部應(yīng)該與地板平行。如果你要坐很長(zhǎng)時(shí)間，應(yīng)該每30分鐘起身活動(dòng)一下胳膊、腿部和頸部。

享受計(jì)算機(jī)吧，但要注意安全。
