二、阅读理解
March 25 is called the National Day of Education on the Safety of Elementary and Middle School Students (NDESEMSS全国中小学生安全教育日). The theme (主题) of the day this year is to give students more knowledge (知识) about safety and make sure that their lives are safe.
A survey showed that school accidents kill more students than anything else. The main accidents come from stampedes (踩踏), earthquakes, fires and sports injuries (伤害).
What can we do to keep ourselves safe Keeping calm is the first and most important rule when facing accidents. But different accidents have different self-protection (自我保护) advice.
A stampede is possible anywhere. The larger a human crowd (人群) is, the more likely (可能的) stampedes become. When students around you begin to push, stand still and try to hold onto something, or stay in a corner until the crowd leaves. If you fall down in a moving crowd, cover your head with both hands.
Earthquakes are common natural disasters (灾害). When you feel the ground shake, drop down, take cover under a desk and hold on. You should stay indoors until the shaking stops. If you are outdoors, don’t stay near buildings, trees or power lines.
When there’s a fire, follow the teachers’ instructions (指示) leave the classroom quickly and use a piece of wet cloth to cover your mouth and nose so that you don’t breathe in smoke.
