In Britain, children go to school from Monday to Friday. School usually starts nine o’clock in the morning and finishes at about three o’clock in the afternoon. Most schools ask their students to wear a school uniform.

School always starts with registration. What is registration? Every child going to school each morning and afternoon is recorded(记录) in a special book. The teacher reads out each child’s name in turn. On hearing his/her name, the child makes a reply(回复) and the teacher writes in the book. From the book, you can see whether(是否) the child is in school or not.

At 9:10, children go to the meeting place. There they sing songs, listen to a story and pray(祈祷).

The first lesson begins at 9:20. They have break time from 10:20 to 10:35. During break time, the children have a snack and play games outdoors. After that, they go back in for another lesson until lunch at 12:00. Afternoon lessons begin at 1:10 and end at 3:15, and children go home. They don’t have a break in the afternoon.

Computers can injure(伤害)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 may 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 more than 50 centimeters from the screen. Don’t forget 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(反射在屏幕上). If the window is in front of you, the sun and the screen will both shine into your eyes.

Your hands and wrists(手腕)

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(肘)as high 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 shouldn’t bend(弯曲) your back when you sit. 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(平行) to the floor. If you are sitting for a long time, get up every half an hour and exercise your arms, legs and neck.

Enjoy your computer, but use it safely.
