主题群:灾害防范 子主题:防范措施 语篇类型:说明文 难度:★★
Every year, hundreds of people are killed at a music festival, a sports event or a parade because of the crowd crush. How can you stay safe then if you come across this kind of accident? 1.
Stay calm and save your energy. Feeling afraid can't save your life. Don't shout. 2. If a crowd crush happens, you'll need all your physical energy to keep yourself safe.
3. Staying at the edge(边缘) of a crowd allows you to get away more quickly. However, if you find yourself in the middle of a dangerous crowd, try to move diagonally(斜地).
Go with the crowd, not against it. If the crowd is moving in one direction, it's best to go with the crowd. 4. If you happen to fall down in a large crowd, try to get up as quickly as possible. If you can't, try to lie on your left side to protect your heart and lungs.
The most important thing is to know when to leave before the crowd crush happens. Once the number of the people reaches six per square metre or more, it becomes very dangerous and you may not be able to get out easily. 5.
Our safety is our responsibility. Be careful and stay safe.
A. Leave right away.
B. Move to the edge of the crowd.
C. Shouting will make you feel tired.
D. Stay with your parents and friends.
E. Here are some suggestions to help you.
F. Fighting against the crowd might make you fall.

1. E 前文提出问题“How can you stay safe then if you come across this kind of accident?”，后文紧接着列出具体的安全建议。E选项起到承上启下的作用，引出下文的防范措施。
2. C 前文提到“不要大喊”，C选项解释了不要大喊的原因——大喊会消耗体力，与上下文逻辑连贯。
3. B 根据“Staying at the edge of a crowd allows you to get away more quickly.”可知，待在人群边缘能让你更快脱身。B选项作为本段的主题句，概括了该部分的建议，符合结构要求。
4. F 前文建议“跟着人群走”，F选项说明了逆着人群走的危害，与前文的建议形成因果逻辑，衔接自然。
5. A 前文提到“Once the number of the people reaches six per square metre or more, it becomes very dangerous”，A选项给出对应的解决方案——立刻离开，与前文的危险提示相呼应，符合安全建议的逻辑。

【分析】
本题是灾害防范主题的任务型阅读题，需结合上下文逻辑匹配选项。解题思路为：先通读全文明确主旨是介绍人群踩踏时的安全防范建议，再分析每个空白处的上下文逻辑（如承上启下、因果关系、主题句等），最后匹配最符合逻辑的选项，排除多余选项。
【解析】
1. 前文提出“遇到人群踩踏如何自保”的问题，后文列出具体安全建议，E选项“Here are some suggestions to help you”起到承上启下的作用，引出下文，故选E；
2. 前文提到“Don't shout”，C选项“Shouting will make you feel tired”解释了不要大喊的原因，与上下文逻辑连贯，故选C；
3. 本段围绕“待在人群边缘利于脱身”展开，B选项“Move to the edge of the crowd”是本段主题句，概括核心建议，故选B；
4. 前文建议“跟着人群走”，F选项“Fighting against the crowd might make you fall”说明逆着人群走的危害，衔接前文建议，故选F；
5. 前文提到人群密度达每平方米6人以上很危险，A选项“Leave right away”给出对应解决方案，符合安全逻辑，故选A。
