300-word composition in the third grade of primary school: Do you know?

Example 1:

Do you know

You know, in our innocent age, we are full of curiosity and infinite imagination.

I like to play with my friends. We are always full of creativity and adventurous spirit. Once, we played hide-and-seek on campus, and I hid in a hidden corner. I couldn't help laughing when I saw my classmates looking around. Everyone laughed and laughed together, and the happy voice echoed in the campus. At that moment, our childlike interest really showed.

I also like drawing with my friends. We doodle on paper with colored crayons. Sometimes, we draw beautiful flowers and lovely animals, and sometimes, we outline a wonderful world of dreams and fantasies. In the process of painting, we can freely express our thoughts and feelings and enjoy the happiness brought by painting.

At school, we have many interesting activities. For example, we often participate in class performances, singing, dancing and reading, and everyone can show their talents. I remember one time, our class sang a touching song, and everyone sang in chorus, laughing and laughing on the stage. At that moment, we felt unity and happiness.

Childlike heart is a valuable asset for our growth. It gives us unlimited imagination and creativity, so that we can learn and grow in happiness. Childlike interest is a treasure, we should cherish it, keep a childlike heart and make our childhood full of sunshine and happiness.

Whether you are playing, drawing or participating in various activities, you can feel the happiness brought by childlike interest. Let's keep childlike fun together and enjoy this wonderful time! Let happiness and laughter always accompany us, and let childlike interest never fade.

Example 2:

Do you know that our world is so wonderful and colorful, full of infinite miracles and surprises?

You know, nature is our best teacher. Every day, when I go out to meet the first ray of sunshine in the morning, I will see a beautiful scenery. Birds are singing happily in the branches, and flowers are swaying in the breeze. I am bathed in the embrace of nature and feel the precious gifts that nature has given us.

You know, friendship is the most important wealth in our life. I have a best friend, and we often share happiness and troubles together. Whether at school or at home, we always support each other tacitly. We played together, studied together and spent a lot of happy time together. With the company of my friends, I feel that no matter what difficulties I encounter, I can go forward bravely.

Do you know that knowledge is the source of our strength? Every day at school, the teacher will bring us new knowledge and skills. I like listening to the teacher in class. Through studying, I can understand the mysteries of the world and broaden my horizons. Knowledge not only makes me smart, but also makes me more confident and brave to face future challenges.

Do you know that family is our warmest harbor? Every day when I come home from school, my mother always greets me at the door and gently brings me into a warm family environment. Eating, chatting and laughing with family filled the room. The warmth of my family gives me strength and peace of mind.

You know, our future is full of hope. Everyone has their own dreams and goals. As long as we study hard and pursue bravely, we will certainly achieve it. I believe I can become an excellent person and make contributions to society.

You know, our world is full of infinite possibilities. Let's cherish every day, explore, learn and grow with our heart. Believe in yourself and the future, and you can create your own beauty.

You know, you are unique, and your existence makes the world more colorful. Believe in yourself and pursue your dreams bravely, and you will certainly create your own wonderful story.
