Japan At public elementary schools in Japan, earthquake drills (演習 ) are held once a month. They teach students safety tips during an earthquake. Regular training helps students escape from earthquakestricken areas without causing any stampedes (踩踏 ). Australia Most students in Australia take firstaid courses at school. They learn basic firstaid knowledge in the class, such as how to call an ambulance (救護車 ) and what to do when someone is hurt. The government is trying to make all kids take such courses. US Most US school buildings have fire escapes (火災(zāi)逃生口 ). A fire escape has platforms with stairs and ladders at each storey of a building.

But traveling might not be that fun for everyone, especially for those who have motion sickness (暈動癥 ). Motion sickness is also called travel sickness. It is a mon experience for many people. Depending on how you travel, it can be called carsickness or seasickness. People with motion sickness feel very unfortable while they are in motion (在移動中 ). They feel sick and dizzy, like the room around them won’t stop spinning. It is generally believed that motion sickness happens when your senses bee confused with each other, Scientific American reported. We use different parts of our body to sense movement. Our eyes tell us if we are moving. The inner ears (內(nèi)耳 ) contain a special liquid (液體 ) that helps us sense our direction and balance. Our muscles (肌肉 ) react to movement. When you move around, these body parts work well together. But when you are in a car or an airplane, they get confused. Your inner ear signals that you’re moving, but your eyes say you’re sitting still because you can’t see that you’re moving. This mismatch gives us motion sickness. But some people are less sensitive to motion sickness. This may be because they have certain genes (基因 ) that prevent mismatching senses, Bethann Hromatka, a geics expert from the US, told the Atlantic. Although there are many ways to deal with motion sickness, scientists believe that the key is to simply try to adapt to it. For example, some astronauts do special exercises that give them mild (輕微的 ) motion sickness. After a week or two, the astronauts bee used to it and don’t feel unfortable anymor
