资源简介
Ⅰ)
Adults use computers on a lot of jobs. Unfortunately,many people have been hurt while using them. Using a computer can affect different parts of your body,like your fingers,arms,shoulders,neck,back,and eyes. Here are some tips for us to protect ourselves when we use computers.
After you’ve started at your computer for 15 minutes or so,try to look away briefly at some distant objects or another part of the room.
Don’t stare at the computer screen for too long a time. Taking breaks from looking at the screen is important not just for your eyes,but for your neck,back and arms. . . and your mind.
