According to a new Ministry of Education survey, students’ safety has become a big problem. Nearly 50 percent of students say they are worried about robbery(抢劫) on the way to and from school. Now in many big cities in China, some schools have taught an unusual lesson: self-protection(自我保护) . Students like this lesson as there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No.25 Middle School and a self-protection expert(专家)，gives young students advice on how to deal with danger.
If you are robbed（抢劫）, keep calm. If you can’t cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police.
If you are in a traffic accident and a car hurts you, you should take down the car number. If it is a bicycle, try to contact  your parents before you let the rider go. This is because you don’t know how seriously you are hurt.
If it is raining hard and there is lightning(闪电), don’t stay in high places and keep away from trees.
When there is a fire, get away as fast as you can. Put wet things on your body and try to find an exit(出口). Do not take the lift!
If someone is drowning(溺水) but you can’t swim, don’t get into the water. Cry out for help.
Remember that danger is never as far away as you think. Take care of yourself at all times!
【小题1】Why do students like the self-protection lesson?

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth rub together to make heat energy. The faster you rub two things together, the more friction ( and heat) you can make. Let’s discover friction!

Many people like animals and keep one or more as pets—dogs, cats and some kinds of birds. If you keep a dog or a cat as a pet, you must know how to look after it. A grown-up(成年) dog needs two meals a day, not more. And it can eat meat, fish, rice and some other things. Dogs like large bones(骨头), but don’t give them chicken bones. Remember to give them much clean water.      A dog should have a clean, dry box for sleeping. Washing it once a week is good for its health. If it is ill, take it to a doctor.
