Safety is the most important thing in our daily lives. However, many accidents happen because of many people's misunderstandings.
First, be careful with cans(罐) of soft drinks. In summer, many people like to put soft drinks in the fridge. This can be very dangerous. If we keep the can in the fridge for too long, the gas inside will expand(膨胀). When we pull open the can, the metal(金属) piece at the top can fly out fast and hurt us. If we want cold cola, put the can in the fridge for less than 45 minutes, or pour it into a cup and add some ice.
Second, watch out during PE class. After doing exercises like pull-ups(引体向上) or sit-ups, some students like to lie down on the ground to relax. This can be dangerous. If their heads hit the ground hard, they might feel uncomfortable, and even stop breathing for a moment. The correct way to relax is to sit down with the hands to support(支撑) the body.
Third, if a lift falls and is about to reach the ground, do not jump! In fact, humans don't have physical power to jump high in such a situation to save themselves. The right action is to press all the floor buttons(按钮) right away. Then, keep the back and head against the wall in a straight line and bend(弯曲) the knees. Lie down on the lift floor if the lift is big or there aren't many people around. This helps protect the body from the shock.
In short, doing the right thing is key to safety. Let's remember these tips and stay safe.
29. What is the correct action to get a cold soft drink?
30. Why is it dangerous to lie down on the ground to relax after the students do sports?
31. What should we do first if a lift with many people falls?
32. Why does the writer think there is a great need to remember these tips?
33. How do you stay safe? Give an example.
