I want to tell you about two important rules in and out of school. It is important to follow them as they can save your health, and even your life.

You come here in the morning and leave only at lunchtime or even in the afternoon. So, it is very important how you spend your time here. When you are in class and sitting at your desk, you must keep your back straight.

If you have eye problems, you need to sit in the first three rows of desks. If you do not see what is on the board, you need to tell your teacher. After each lesson, you need to do exercises or take a walk. These simple rules will help you keep yourself healthy.

When you leave the house and go to school, you must be very careful on the roads. The road is a very dangerous place.

Before crossing the road, you must look around and make sure that there is no car. Never use your phone and earphones outside. The picture shows how you must not walk on the street. You must see and hear everything around you. So, you must not use gadgets outside.

The picture shows how you should not sit and how you should.

You spend most of your day at school.

You should always look where you go ппжпжпжжпжпжпжпп
