主题语境练18　选择性必修第二册　UNIT 5 灾害防范 限时30分钟 阅读理解 A　(原创)　体裁:说明文　主题语境:安全常识和自我防护　难度:★★☆☆☆ 　　On the night of Oct. 29, tens of thousands of R.O. Koreans went out to celebrate Halloween. Unfortunately, this event quickly turned into one of the country􀆳s worst disasters. A crowd of mostly young people started to crowd into a narrow alley (小巷) until it was overcrowded. They reported that it was difficult to even breathe. Up till Nov. 13, 158 people had died. So, how can we learn a lesson from this accident and protect ourselves from similar future events? 1. Make a note in your head of all the exits for the area you are in. 2. When you start to feel uncomfortable in the crowd, this is the time to start thinking of leaving. 3. Stay on your feet. 4. Do not push and shout. Save your energy and do not cause even more alarm. 5. Keep your hands up by your chest. It gives you movement and protects your chest. 6. Stick together—if you see someone who needs help, reach out to them. 7. Try to stay calm to control your breathing. The lesson we should learn from this is to not only trust your deep feeling and prioritize (优先) your own comfort, but also recognize how dangerous public gatherings can be. Did you know that in a crowd with a density of more than six people per square meter, people lose control over the movement of their own bodies as the whole crowd can act like water? That means pressure waves can travel through it and cause the whole group to fall at once. Crowd management is necessary when it comes to big public events. 本文通过韩国踩踏事件,说明了在踩踏中幸存的方法。 1.Which is the first thing to do if you are in a crowd? A. Calmly controlling breathing. B. Mentally noticing all exits. C. Determining the time to leave. D. Rising to your feet. 答案与解析　B　细节理解题。 由第二段第1条“记住你所在区域的所有出口”可知, 心里记下出口,知道怎么出去最重要,故B项正确。 2.What leads to the falling of a crowd with a density of 8 people per square meter? A. Body movement. B. Water. C. Pressure waves. D. Narrow exits. 答案与解析　C　细节理解题。由最后一段可知,当每平方米超过6人时,他们无法再按照自己的选择去哪
