Giới thiệu về bản thân

Hello everyone! First of all, thank you very much for giving me the opportunity to introduce myself. I am very happy and excited to be here today. My name is Ngọc, and I am 10 years old. I come from Vietnam, a beautiful country in Southeast Asia. Vietnam is famous for its breathtaking scenery, delicious food, rich culture, and friendly people. I am very proud to be Vietnamese because my country has a long history and many wonderful traditions. There are many famous places in Vietnam, such as beautiful beaches, green mountains, peaceful rivers, and exciting cities. I hope that one day I can visit every part of my country and learn more about its history and culture. I am a primary school student. I enjoy going to school every day because school is a place where I can learn many new things and spend time with my wonderful teachers and classmates. My teachers are kind, patient, and always encourage me to study hard. They teach me not only school subjects but also important life lessons such as honesty, kindness, responsibility, and respect. I appreciate everything they do for me, and I always try my best to make them proud. I think I am a friendly, cheerful, honest, and helpful person. I enjoy making new friends because I believe everyone has something special to share. Whenever someone needs help, I always try my best to support them. I like smiling because I think a smile can make people feel happier. I also believe that good manners are very important. Saying "please," "thank you," and "sorry" may seem simple, but these words show respect and kindness to other people. My favorite subject is English. English is my favorite because it allows me to communicate with people from different countries around the world. I enjoy learning new vocabulary, practicing conversations, reading short stories, singing English songs, and watching English cartoons. Sometimes English grammar is difficult, but I never give up because I know that practice makes perfect. Every day I try to learn at least a few new words and use them in sentences. I believe that learning English will help me have more opportunities in the future. Besides English, I also enjoy learning science. Science helps me understand the amazing world around us. I like learning about animals, plants, the human body, space, weather, and technology. Every time I discover something new, I become even more curious. I think the world is full of interesting things waiting to be explored. Reading books is another activity that I enjoy very much. Books allow me to travel to different places through my imagination. Some books tell exciting adventures, while others teach useful knowledge about nature, history, or famous people. Reading helps me improve my vocabulary, develop my imagination, and become a better learner. I hope I can read many more books as I grow up. In my free time, I have many hobbies. I love drawing colorful pictures because drawing allows me to express my imagination and creativity. Sometimes I draw beautiful flowers, lovely animals, landscapes, or cartoon characters. Drawing always makes me feel relaxed and happy. I also enjoy listening to music. Music helps me relax after studying and gives me positive energy. Sometimes I sing along with my favorite songs because singing makes me feel confident and cheerful. I also enjoy watching cartoons and educational videos because they are both entertaining and informative. Playing games is another hobby of mine. I enjoy playing games because they help me relax and have fun with my friends. However, I understand that studying is more important, so I always try to balance my study time and my free time. I think managing time wisely is an important skill that everyone should learn. I also enjoy outdoor activities. I like riding my bicycle, walking in the park, playing badminton, and spending time with my friends. Outdoor activities keep me healthy and give me the chance to enjoy fresh air and sunshine. Sometimes my friends and I play games together, tell funny stories, or simply enjoy talking about our school life. These moments always make me smile. My family is the most important part of my life. I love my family very much because they always care about me and support me. My parents encourage me whenever I feel sad or face difficulties. They teach me many valuable lessons about life, such as working hard, being honest, respecting others, and never giving up. We often have meals together, watch movies, talk about our day, and travel during holidays. Spending time with my family always makes me feel warm, safe, and happy. I also believe that friendship is one of the greatest gifts in life. Good friends help each other, share happiness, and support each other during difficult times. I always try to be a loyal, kind, and trustworthy friend. I think true friendship is based on honesty, respect, and understanding. Another thing I enjoy is learning about different countries and cultures. Every country has its own traditions, languages, food, and festivals. I hope I can travel around the world in the future to experience different cultures, meet new people, taste delicious food, and visit famous landmarks. Traveling is one of the best ways to learn about the world. Technology is another topic that interests me. Computers, robots, artificial intelligence, and the Internet have changed our lives in many positive ways. Technology helps us study, communicate, and discover information more easily than ever before. I enjoy learning about new inventions because they make our lives better and more convenient. I also care about nature and the environment. I believe that everyone should protect our planet by planting trees, saving water, reducing plastic waste, and keeping our surroundings clean. Even small actions can make a big difference if everyone works together. I always try to throw rubbish into bins and keep my classroom clean because I want to help protect the environment. One of my dreams is to become a successful person who can help other people. I know that success does not come easily. It requires patience, determination, discipline, and hard work. I understand that I must continue learning every day if I want to achieve my goals. Even if I make mistakes, I will learn from them and keep trying. I also hope to improve my English, learn new skills, read more books, become more confident, and discover new knowledge every day. I believe that every small step I take today will help me build a brighter future tomorrow. My parents and teachers always encourage me to do my best, and I want to make them proud by becoming a kind, responsible, and hardworking person. I think life is a wonderful journey full of opportunities and challenges. Every day gives us a chance to learn something new, improve ourselves, and help others. I believe that with confidence, determination, kindness, and hard work, we can achieve our dreams and become better people. Thank you very much for listening to my self-introduction. I hope we can become good friends, learn many wonderful things together, and create happy memories. I wish all of you good health, happiness, success, and a bright future.Thank you very much, and have a wonderful day!

tớ cũng bị nhưng mà là bạn nguyễn quang vinh

trường tiểu học ba chẽ

trường chuyên hạ long (cấp 2+ cấp 3)

  • Bút bi : Cắm ngòi xuống để viết thì đầu bút "cứng" , rút ra một lúc mực khô hoặc ngòi thụt vào, đầu bút hơi dính mực nên "nhớt".
  • Cây kem : Cắm vào miệng thì còn cứng, rút ra một lúc thì mềm, chảy và hơi nhớt.

Đáp án phổ biến là: Cá trong cờ cá ngựa.

Giải thích: Quân trong trò chơi cờ cá ngựa ở trên cạn, nhưng khi chơi thì nó vẫn "biết bơi" (di chuyển theo cách nói vui).

Ngoài ra còn có một đáp án vui khác là:

  • Cá bằng nhựa/đồ chơi – ở trên cạn nhưng thả xuống nước thì vẫn "biết bơi".

Nếu đây là câu đố trong một bộ câu đố cụ thể thì cho mình biết nhé, vì có nhiều đáp án chơi chữ khác nhau.

Nếu bạn hỏi "Tại sao lửa có thể bốc ở dưới sông?" thì có vài nguyên nhân khoa học:

  1. Khí mê-tan (CH₄) thoát lên từ đáy sông.
    • Dưới đáy sông có nhiều xác động, thực vật phân hủy.
    • Quá trình này tạo ra khí mê-tan.
    • Khi khí nổi lên mặt nước và gặp nguồn lửa (bật lửa, tia lửa...), khí sẽ cháy. Nhìn từ xa có cảm giác như lửa bốc lên từ dưới sông.
  2. Có dầu hoặc xăng nổi trên mặt nước.
    • Dầu và xăng nhẹ hơn nước nên nổi lên trên.
    • Khi bắt lửa, chính lớp dầu đang cháy chứ không phải nước.
  3. Nước không cháy.
    • Nước (H₂O) đã là sản phẩm sau khi hiđrô cháy với ôxi nên bản thân nước không thể cháy.
    • Điều đang cháy là khí hoặc chất dễ cháy có trong hoặc trên mặt nước, chứ không phải nước.

Vì vậy, lửa không cháy dưới nước theo nghĩa nước bị cháy, mà là khí mê-tan hoặc các chất dễ cháy thoát ra từ dưới sông hoặc nổi trên mặt nước bị bắt lửa.

Hoa tay.

Giải thích: "Hoa tay" là các đường vân xoáy trên đầu ngón tay. Khi bạn "bứt" (xòe hoặc giơ) các ngón tay ra thì sẽ nhìn thấy nhiều "hoa tay" hơn. Đây là một cách chơi chữ vui.

Nếu bạn đang nói đến cây thật thì cũng có một số loài hoa càng ngắt càng kích thích ra nhiều hoa mới, chẳng hạn:

  • Hoa mười giờ
  • Hoa cúc
  • Hoa dạ yến thảo
  • Hoa hồng (cắt tỉa đúng cách sẽ ra nhiều đợt hoa)

Còn nếu đây là câu đố mẹo thì đáp án phổ biến nhất là hoa tay.
