Anti-epidemic speech 800 words, fourth grade primary school volume 1

Dear teachers and students, Hello everyone! The topic of my speech today is health. Everyone knew that health was very important. In our daily lives, there are many aspects that are closely related to health. Let's talk about personal hygiene first. We have to keep our bodies clean every day. Washing our hands is a very simple but very important habit. You must wash your hands before and after eating, after sneezing, and after going out. If we eat with dirty hands, the invisible bacteria will enter our bodies with the food and make us sick. Moreover, we have to change our clothes and bedding frequently. Don't spit on the ground, and don't mix our personal hygiene products with others. Also, the environment we live in and the school's environmental hygiene are also very important. We have to clean up the campus. We can't leave any dead spots. The garbage produced every day must also be cleaned up in time and thrown to the designated place. This way, bacteria won't breed easily, and diseases will stay away from us. In addition, spring was the season when infectious diseases were prone to occur. When the temperature rose in spring, many microorganisms began to become active. It was easy for infectious diseases such as hand, foot and mouth disease and flu to occur. There were many people in the school. If they did not pay attention to hygiene, infectious diseases would spread quickly. Therefore, we have to open the windows more often to keep the air in the classroom fresh, but we also have to be careful not to catch a cold from the wind. Sometimes, we can also disinfect the air in the room. We also need to learn more about common infectious diseases, such as flu, hand, foot and mouth disease, and malaria. If you feel unwell, you must tell your teacher or parents in time, see a doctor, and take medicine according to the doctor's instructions. If necessary, they could even get the corresponding vaccine. Finally, everyone should also pay attention to rest and sleep. He had to live a regular life every day, balance work and rest, and ensure adequate sleep time. This way, our body's immunity will be stronger and we can better resist diseases. Let's start from the little things around us, pay attention to hygiene, and keep healthy! Thank you, everyone! <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

"To prevent the return of the epidemic" Dear students, Hello everyone! We all know that the new crown virus is like a naughty little monster. It has caused trouble in our world and brought a lot of trouble to everyone. Although it didn't seem to be that powerful now, this little monster hadn't been completely defeated. It might make a comeback. What should we do to prevent this little monster from causing trouble again? First of all, before we go to school every day, we have to take our body temperature. If you feel that your body is warm and different from usual, you must tell your parents or teachers. When she went out, she had to wear a small mask firmly on her face, as if she was wearing a protective armor on her little face. This mask could not be taken off casually. He had to wear it all the time. If there was hand sanitizer, it would be better to bring a small bottle with us. This way, after we touched something, we could disinfect our hands. If there were disposable gloves, we could also wear them. When we get to school, if a teacher takes our temperature, we have to cooperate obediently. When taking the elevator, besides wearing a mask, there was also a trick to pressing the elevator button. It was best to use a tissue or other disposable item to press the button and throw it into the trash can after pressing it. If he pressed it directly with his hands, he would have to wash his hands quickly. In the classroom, we should open the windows more often to let fresh air in. This way, the little monsters won't like to stay in our classroom. When playing or chatting with his classmates, he had to keep a little distance. It was like setting up a small circle for the little monster that it could not enter. He was also particular about eating. If they were eating their own food, they had to heat it up in the microwave before eating. If they were to eat in the canteen, everyone should sit separately. They should not face each other, and they should not chat while eating. It would be fine if they finished eating quickly. After school, we first took off our clothes and masks, and then let Mom and Dad disinfect our clothes and soles with alcohol. We also have to wash our hands with hand sanitizer. We can also take a shower and put the dirty clothes into the washing machine to wash and dry. Students, each of us is a small soldier. As long as we do these small things well, we can keep the little monsters outside and let our lives be safe. Thank you, everyone! <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some anti-epidemic stories that may happen around primary school students: ** 1. Restrictions on family activities ** 1. The Spring Festival, which was originally full of expectations, became different. Many families canceled their travel plans. For example, some children had planned to travel with their parents, but they could only stay at home. Moreover, even ordinary activities such as walking along the canal near the neighborhood were banned. The children could not move freely like before. 2. New Year activities were also restricted. For example, when some children were about to ask their elders for New Year's money, they were told that they couldn't go anywhere. There were also children's relatives who were far away in Hubei who were going to come home for the New Year. The family had prepared food early, but because of the epidemic, their relatives could not come. 3. Entertainment activities were limited, and children could not play with other children. For example, a child's friend came to play with him, but he could not go out. Moreover, the entry and exit of the community were strictly restricted. One had to wear a mask when taking the bus. The streets were no longer as lively as they were during the Spring Festival in previous years. It had become quiet. The road back to his hometown might be blocked and it was impossible to enter and exit. ** II. Positive Contribution to the Fight Against the Epidemic ** 1. Many medical staff and the People's Liberation Army went to the front line of the anti-epidemic in Hubei, and a large number of medical supplies gathered in Hubei. The 84-year-old grandfather of Zhong Nanshan rushed to Hubei to analyze and study the prevention and control countermeasures. These deeds made the children feel everyone's efforts to fight the epidemic. 2. Ordinary people were also contributing to the fight against the epidemic. Although the children could not go to the front line to fight the epidemic, they could stay at home. This was also a kind of contribution. For example, some children would listen to their parents 'words, do their homework seriously at home, read books, watch TV, wear masks, wash their hands frequently, pay attention to hygiene, don't gather, don't eat together, and also publicize and share knowledge about virus prevention and control in their circle of friends. 3. In terms of school education, teachers were actively changing their teaching methods. For example, some teachers would use Siwo Whiteboard 5, Nail, CCTalk and other software to teach online, make knowledge capsules, grade homework online, listen to students read recordings, communicate with parents and students in time, and grasp the students 'learning situation at home. Moreover, teachers would guide students to learn knowledge outside of textbooks through the epidemic, such as letting students record small videos to cheer for their motherland and Wuhan1, writing articles to pay tribute to pioneers, and copying copies of paintings to express their protection against viruses. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are examples of 20 calculation questions that may be involved in the first volume of the fourth grade of primary school (vertical, off-form, simple calculation): ** 1. Horizontal calculation (10 lines, example of dividing a three-digit number by a two-digit number)** 1. $324÷12 =$ 2. $456÷18 =$ 3. $567÷21 =$ 4. $298÷13 =$ 5. $345÷15 =$ 6. $490÷25 =$ 7. $512÷16 =$ 8. $630÷21 =$ 9. $728÷28 =$ 10. $840÷35 =$ ** 2. Free Form Calculation (5)** 1. $25×(34 + 16) - 120$ - First calculate the number in the parenthesis: $34+16 = 50$, then multiply: $25×50 = 1250$, and finally subtract: $1250 - 120 = 1130$. 2. $128 + 72÷8×5$ - Divide: $72 div8 = 9$, multiply: $9×5 = 45$, and add: $128+45 = 173$. 3. $(45 - 18)×(32 + 16)$ - First calculate the numbers in the parenthesis: $45 - 18 = 27$,$32+16 = 48$, then multiply: $27×48 = 1296$. 4. $360÷(72÷8)$ - First, he calculated the number in the parenthesis: $72 div8 = 9$, then he calculated the division: $360 div9 = 40$. 5. $158 - (64 + 36÷9)$ - First, he calculated the division in the parenthesis: $36 div9 = 4$. Then, he calculated the addition in the parenthesis: $64 + 4 = 68$. Finally, he calculated the deduction: $158 - 68 = 90$. ** 3. Simple calculation (5)** 1. $25×36$ - It could be converted to: $25×4×9 = 100×9 = 900$. 2. $125×88$ - It was converted to $125×8×11 = 1000×11 = 11000$. 3. $45×99$ - It is written as: $45×(100 - 1)=45×100 - 45×1 = 4500 - 45 = 4455$. 4. $36×102$ - It became: $36×(100 + 2)=36×100 + 36×2 = 3600 + 72 = 3672$. 5. $23×18 + 77×18$ - Using the multiplication distribution law: $(23 + 77)×18 = 100×18 = 1800$. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Dear teachers and students, Hello everyone! Today, I want to talk to you about the importance of goals. A goal is like a bright lighthouse in the distance, guiding the ship in the vast sea. A goal is the source of motivation for us to move forward. Every great achievement came from a small goal and a relentless struggle. Everyone knew that the dream of a bird was to fly to the blue sky, the dream of a fish was to swim in the sea, and the dream of a horse was to gallop on the endless prairie. What about us? As fourth-year students, we are at an age full of hope and possibilities. We should have our own goals. Let me tell you a story. There was an American girl named Sylvia. Her family was very good and her parents could give her a lot of help. Her dream was to be a TV host. She felt that she had the talent in this area because she could get the " truth " from others. She always said," As long as you give me a chance, I believe I will succeed." However, all she did was wait. She did not put in any practical effort. In the end, no miracle happened. Another girl, Cindy, also wanted to be a TV host. She went to work during the day and attended night classes in the university's news department at night. After graduation, she went to every radio and television station in Los Angeles in order to find a job. Although she was rejected at first because she had no experience, she did not back down. When she saw a small television station in North Dakota hiring a weather forecast, she seized the opportunity even though she did not like the North. In the end, after hard work, she successfully became a famous television host. This story tells us that if you have a goal and don't fight for it, you can only dream. The same principle applies to our studies and daily life. For example, when studying mathematics, we can set a small goal for ourselves. This month, we have to memorize the multiplication formula and then work hard to achieve it. In Chinese learning, we can set a goal of reading a few interesting extra-cursory books this semester, and we have to be able to share the stories in the books and our own insights with our classmates. If we want to be a painter, we must start to learn the basics of painting seriously now. We must not be afraid of drawing mistakes and keep practicing. If we want to be an athlete, we must actively participate in physical training every day and not be afraid of hardship. Students, from now on, let's set our own goals and then water them with hard work and sweat, so that they can take root and sprout like seeds and grow healthily. I believe that as long as we persist in fighting, no matter how big or small the goal is, one day we will be able to achieve it and make ourselves better. Thank you, everyone! <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Life Under the Epidemic The epidemic had changed the world. The bustling streets became deserted. There were no bustling crowds, and no car horns. The school could not hold classes normally, but the teachers had worked hard to prepare online classes. The first time I went online, I was very nervous. Looking at the teacher on the screen, I was curious and flustered. But slowly, I was able to keep up with the pace of the class. However, online classes were very different from real classes. I couldn't talk to the teachers or share my thoughts like in school, and I couldn't play with my classmates during class. My parents told me that many people are working hard to fight the epidemic. The medical staff wore thick protective clothing to treat the sick and save people. The volunteers were also helping in every corner. I know that everyone is working hard. I have to be obedient, go online, finish my homework on time, wash my hands frequently, wear a mask, and take good care of myself. I hope the epidemic will end soon, so that I can return to the campus full of laughter and the city can become lively again. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
