Common sense composition of building escape

The teacher taught us three ways to escape from tall buildings in earthquakes and fires. Guo Xian, an instructor, asked us, "Guess what tools you will use to escape." A classmate said, "jump off a building!" " "We laughed, and instructor Guo said," Jump off a building. You can't jump off a building unless you have lived enough! "Then, our first escape tool is an escape rope, which can be made of sheets and curtains at home. When using the escape rope, the whole body should be in a straight line. Put your hands above your head, straighten your feet, step on the knot at the joint and climb down slowly. Be careful that your body must be in a straight line when climbing, but this escape rope is suitable for houses below the third floor. " After that, instructor Guo asked another instructor Liao to show us. Instructor Liao demonstrated from a two-story platform. First, he put his feet on the knot, raised his hand over his head and slowly retreated. Suddenly, the rope shook, and I couldn't help shaking: "Ah!" I'm afraid instructor Liao is going to fall. Fortunately, it was a false alarm After instructor Liao retreated to the ground, we all clapped our hands involuntarily. Chenchen said, "God, that's terrible! If I die, I won't climb that escape rope. Too scary! " This is under the third floor. What about the one above the third floor like mine? Then, instructor Guo introduced us to the second escape method-ladder. Instructor Guo said: "This ladder is suitable for houses above the third floor and below the tenth floor. When using a ladder, the whole body should be straight, and both hands should grasp the wooden stick, which is similar to climbing a ladder. Remember not to grab the rope, but the stick in the middle. " Instructor Liao demonstrated for us. Instructor Liao stepped on the ladder first, grabbed the stick with both hands and climbed down slowly, which made me jumpy. Every time the ladder shakes, my heart is tense. It was not until after instructor Liao landed safely that I finally breathed a sigh of relief and finally put down the stone in my heart. At this time, a classmate asked: "Teacher Guo, what you introduced is the situation on the tenth floor. How can I escape from the thirteenth floor of my house, that is, above the tenth floor? " Instructor Guo mysteriously said to us, "Yes, I will introduce the third escape tool immediately, which is suitable for the tenth floor or above, but this escape tool is much more comfortable than the first two!" ""much more comfortable? " I thought, "What could be more mysterious and comfortable than the first two? What is this? "I'm looking forward to the third escape tool. Instructor Guo cleared his throat and said, "This third escape tool is suitable for houses above the tenth floor. Its name is glider. " Said, pointing to the left front hanging a wire, "what? A wire? "I feel incredible." I can bend and break that thin thread effortlessly. How to use it to escape? "Still the most comfortable?" Chen Lala my skirts: "I even wonder if Instructor Guo is fooling us. What's the use of that with a small wire? " I shook my head to show that I didn't know. Instructor Guo said, "Don't underestimate this wire. On May 2, 2008, a group of tourists from Taiwan Province Province were trapped on the cable car, and fire officers and soldiers rescued them with this glider! " Instructor Guo said, instructor Liao did. Instructor Liao tied something similar to a seat belt around his waist and hung it on the wire. "The body leans back slightly and slowly slides down against the wall." Instructor Guo explained. I looked at the wire carefully and suddenly found the mystery: originally, the wire is fixed on the crane, and people can be safely sent to the ground without any effort by using the principle of the crane. I was dumbfounded, so that's it! No wonder this is the most comfortable escape tool! Ask me in the morning, "If an earthquake really came, which one would you choose?" "Ladder!" I said, "This thing may be at home, but what if there is nothing?" Chen said, "Then jump off the building!" Ha ha! Then, Mr. Guo showed us some bloody lessons-more than 0/00 people were killed or injured in the explosion of a chemical plant,/0/4 young lives were lost when a tricycle overturned and fell into the river,/0/0 students were killed in a school stampede accident, and 43 lives were lost in a ballroom fire ... I couldn't help but feel shocked when I saw these terrible figures. Chen uttered a sigh of "tut-tut": "If you had been more careful, paid more attention and had more safety knowledge, so many people might not have died." After reading these bloody lessons, instructor Guo asked us what we thought, and everyone's answer was the same: "sympathy, shock."
