On May 2, 2008, an earthquake of magnitude 8.0 occurred in Wenchuan, Sichuan, which shocked the whole world. In order to reduce school casualties in the event of an earthquake, the state stipulates that all primary and secondary schools should conduct earthquake drills. This will make us exhausted. Every day between classes, it is changed to "earthquake drill". Don't you think this will beat us to death? Hey.
The bell rang during the big recess, and the whole class was on high alert. At the slightest sign of trouble, they chattered. Look at my deskmate Chen Hanxing. She looks a little excited and nervous. She kept fiddling with her hair. She said, Good death. Alas, women are like this, and they have to look good when they die.
Just then, the bell rang "clang, clang, clang", and everyone walked down the stairs unhurriedly, unhurriedly and swaggeringly. Unexpectedly, our class came last in the whole school, and the headmaster was so angry that he waited for us at the stairs for a long time. Unfortunately, he was swept. Shh, keep your voice down. I heard it was a 5000-word comment on the Importance of Earthquake Prevention and Disaster Reduction!
The next day, I didn't notice whether the teacher's right hand could move, but the atmosphere in class today was so dignified that the bell came as scheduled. I can't even get out of the atmosphere, waiting for the "alarm". "Bang, bang, bang," everyone is frightened now, rushing out of the classroom like a flood and flying down. Arriving at the stairs, I didn't expect everyone to "make an appointment" with the principal. "What's the matter with you?" I was late yesterday and I haven't had time to ring the bell today. It's good for you to strike first! "The headmaster is finally angry with us today. It is said that the teacher's review of 5000 words has become 10000 words. No wonder the Chinese homework hasn't been corrected these days, so that's it. Ha ha, just kidding, in fact, we are all practicing seriously.
Through your unremitting efforts, we have passed the provincial acceptance and become an "excellent model school for earthquake prevention and disaster reduction".
Today, my brother and I went to Shaoxing Science and Technology Museum to visit the popular science exhibition with the theme of "earthquake prevention and disaster reduction". This exhibition mainly introduces us the knowledge about earthquakes and fires, the related contents of earthquake prevention and disaster reduction, and the correct methods to deal with other natural disasters in an intuitive form. We also watched a free 3D movie. This visit made me learn a lot about "earthquake prevention and disaster reduction", and the harvest was really not small!
The earthquake brought us a lot of harm. For example, lifeline damage, casualties, fire, surface damage, house collapse. The biggest loss of the earthquake is casualties. 1558, due to the earthquake, there were more than 830,000 casualties, which was the largest year in the world. The Tangshan earthquake killed more than 240,000 people, making it the deadliest earthquake in the 20th century. Earthquakes will also cause great damage to railways, pipelines and other lives. I remember1July 28th, 976, an earthquake of magnitude 7.8 occurred in Tangshan City, Hebei Province.
In an instant, a city with a population of one million turned into ruins, causing 240,000 casualties and more than 6,543.8+0.6 million serious injuries, which brought huge losses to human daily life and economic development and shocked the world. However, without the movement and change of the earth, there would be no beautiful and colorful world! ! ! After the earthquake,' rock' is a book that records history. There is a kind of rock called alkali flow Yanfu, which is produced in Tianchi, Jilin. The reason is that volcanic gas separated from magma is' frozen' in pumice, and bubbles account for more than 70% of the total rock, so they can float on the water, so they are called pumice.
After visiting this popular science exhibition, I understand a truth. Facing disasters is the scientific understanding and the ability to face them correctly that each of us should have. Many times, a little more common sense can save a life. How brave the refugees in the earthquake were. They rush to their own lives, to protect their families and to get a complete and happy family. We should also lend a helping hand to help the victims. Here, I want to say loudly: "I want to be a little soldier before the earthquake."
Today, we conducted an emergency drill for earthquake prevention and disaster reduction in Duhongfa Primary School!
The exercise has begun. At this time, there was a sound of "Oh-Woo-"on the radio. As if the end of the world was coming, the dog king covered his head and nose with a towel in his right hand and hid under the table, making a banging noise. The classroom is full of students' panic! How great I am! After a while, the "air raid alarm" sounded. One by one, we stood up and screamed, and we hurried into the corridor like we were in a hurry. One by one, orderly, lined up into the stairwell, which was blocked! I look forward to it, I look forward to it, wow! This is a spectacular scene. The front is dark, like a big black cloth. The students are very scared. They covered their noses with their hands and waited for three or four seconds to "open to traffic". Under the guidance of the teacher, we finally opened to traffic! We all hurried downstairs and didn't dare to neglect at all!
Downstairs, we found that the playground was covered with orange smoke, just like an orange veil. The playground is crowded with people, all squatting with towels over their noses after working overtime. We walked through the crowd and came to our area. After a big circle, Liu Liangrong, the squad leader, began to count carefully, and we all squatted and waited for the "lifting alarm" to sound. Students, began to talk in succession, the playground was crowded with people, and the comments spread all over the playground! The teacher doesn't know how to say "get down!" I remembered that the stairwell was really dangerous just now. Fortunately, we have the guidance of the teacher, otherwise we would have been injured in the real earthquake! Alas, I still need to learn more about earthquake prevention in the future! Otherwise, in the real disaster, we humans are so small!
I was just thinking about it when I suddenly thought of "disarming the alarm". We lined up in two neat teams, braved the drizzle and prepared to go back to the classroom. This drill is really meaningful! I think we should learn more knowledge about earthquake prevention in the future, otherwise we can't protect ourselves in the disaster.
What is a disaster? Disaster is a serious damage to life and property caused by man-made or natural reasons. China is prone to natural disasters, such as floods, droughts, earthquakes and mudslides. Among them, the earthquake has the most direct impact on our lives. I believe everyone still remembers the Wenchuan earthquake in 2008. Six years ago, on May 12, an earthquake measuring 8.0 on the Richter scale occurred in Wenchuan County, Sichuan Province. According to relevant statistics, * * * has 69,227 dead, 374,643 injured and17,923 missing, among which 6,376 students died, and the direct economic loss is as high as 845 1 100 million yuan. This is the biggest earthquake disaster in China since the founding of the People's Republic of China.
After the Wenchuan earthquake, people all over the country were deeply immersed in great grief. But the dead are gone, leaving us not only mourning, but also considering how to prevent disasters like earthquakes.
In my opinion, we must have a good attitude after the earthquake, keep a cool head in times of crisis, and don't panic and blindly choose to jump off a building. If you want to stay away from outdoor buildings, try to stay in an open place. If you can't escape in time at home, you can hide under solid furniture or in a corner, or you can move to a kitchen or bathroom with many load-bearing walls and small space to hide for a while. Because these places have strong binding force, especially the pipeline has good supporting force and large seismic coefficient after treatment.
You can also evaluate the situation according to the building layout and indoor conditions, find safe spaces and passages, and avoid and reduce casualties. In school, you should be in a relatively strong and safe house during the earthquake, and you can hide under the desk, beside the podium, in the boiling water room in the teaching building, and in the room supported by pipes. You must never run around or jump down from the upstairs. In public places, such as cinemas, libraries, shopping malls and amusement parks. , should seriously listen to the command of the staff, as soon as possible to evacuate from the safety exit. Don't escape alone or take the elevator.
Although the disaster is merciless, people are affectionate. Whenever a disaster comes, as long as we are United, one side is in trouble and all sides support us, we will surely overcome all kinds of difficulties and rebuild a happy new home.
We should strengthen the study of earthquake science knowledge and correctly master the methods of earthquake prevention and self-help and mutual rescue.
All of us should listen to the earthquake warning, learn to look at the signs before the earthquake, such as the abnormal flying, fleeing and barking of animals, and also prevent the occurrence of disasters, so that the morning paper can be withdrawn early.
When an earthquake occurs, the indoor triangular space formed by the collapse of houses is often a relatively safe place for people to live. Especially in architecture, people choose kitchen, bathroom and other places with small space, and there are spaces and corners that are not easy to collapse. Tables, beds and other places with solid furniture space can be shockproof. Protect your head with a cushion in time. Don't jump off a building blindly, use the elevator. All of us must use scientific methods to protect ourselves and our homes and prevent disasters.
Today is the day of the school earthquake exercise, and all the teachers and students participated. The teacher has explained the specific situation to all of us and every classmate over and over again. The teacher's urgent cry "An earthquake is coming" came from the radio. We all rushed out with our schoolbags on our shoulders. Every student didn't want to fall behind and ran to the playground like crazy, while the teacher kept order and evacuated the students in an orderly way.
All the teachers and students in the school are evacuated at the specified time, and all of us should learn to save ourselves.
We should all read more books on earthquake prevention and disaster reduction. Tell everyone around you the knowledge of earthquake prevention and disaster reduction, let this knowledge spread from one to ten, and let everyone know that when the earthquake comes, everyone knows how to protect themselves and reduce the disasters caused by the earthquake. Let this knowledge accompany all of us, and let all of us have a sense of earthquake prevention.
We are all builders and defenders of the motherland. Let's act quickly to prevent disaster. Everyone is responsible for earthquake prevention and disaster reduction. Let's wish the earth a better and better tomorrow!
On Friday afternoon, our school held an "earthquake drill".
After singing in the afternoon, just after taking out the English book, the school loudspeaker began to inform: "Attention, students, the earthquake-proof exercise begins now."
"Tick-tock, tick-tock ..." With a sharp whistle, Teacher Song ran over and shouted, "Quick, hide under the table, quick." The teacher's orders could not be disobeyed, and all the students immediately hid under the table.
Soon, the whistle sounded again, and Teacher Song issued another instruction: "Quick, run to the playground and hold your head." We are like bees running around in danger, holding our heads and running to the playground. But the corridor is crowded with people, and it is really difficult to move. Although the teacher kept commanding, waving and gesturing, we listened, but our hands and feet still didn't listen to the command and just ran down. If viewed from a distance, this scene must look like swarms of wasps fleeing downwards.
I finally ran down the stairs and was about to run to the playground. My friend accidentally fell and fell to the ground. I was so anxious that I shouted, "Get up, there are so many people, people will step on you, or you will die." She immediately got up and followed me to continue running. But after all, there was a sea of people. We ran together and were soon dispersed by the crowd. Although I was very careful, I was unfortunately trampled by a boy. Wow, it hurts. I grinned and screamed. The boy was a gentleman, turned his head and smiled and said sorry to me, and was soon drowned in the crowd. Alas, this young lady has many adults, so I don't want to care so much. Anyway, he didn't mean to, and he apologized to me. Later, on second thought, if the earthquake really comes, don't step on it, just get a slap. Thank god for his escape, and maybe even thank him.
This earthquake exercise taught me a lot. First, keep a calm mind, relax yourself and calm your heart during the earthquake. Second, don't push or walk slowly in an earthquake, or your life will be hard to protect. Third, the first thing to do in an earthquake is to hide under the table, and then you can quickly run to an open place to avoid disaster.
