That day, the math class passed quickly, and then, it was our favorite physical education class. As soon as the bell rang, the teacher announced the class was over. Like birds just flying out of cages, we rushed out of the classroom and ran to the playground. When I was sweating and thirsty, I remembered that there was water in the classroom and hurried back to the classroom. As soon as I entered the classroom, I saw my deskmate Chen Haotian sitting in her seat, frowning for a while, touching her head for a while, drawing on paper for a while, laughing for a while, as if possessed. I approached him carefully, and when I saw it, it turned out that he was doing his homework! I breathed a sigh of relief and said, "Chen Haotian, your strange movements and expressions just now really scared me to death." "By the way, why don't you go out to play?" I asked curiously. He looked up and said, "This question is really difficult! I want to overcome this difficulty. " "Hey, this problem is not easy to solve. Just go home and ask Mom and Dad!" Hearing this, Chen Haotian shook his head and said, "If we just want to escape when we encounter problems now, and don't think hard, we will definitely achieve nothing when we grow up." Then bend your head and calculate on the draft paper.

After listening to his words, I made up my mind to learn from him and be a good boy who thinks seriously when encountering problems and treats his studies diligently!

2. Praise my classmate's 300-word composition in Grade Three.

My classmate is Gao. Tall eyes are round, like two black grapes. The face is as red as a red apple. Tall hair is as black as a dark cloud. Every time after class, Gao doesn't play on the playground, because he studies better and likes reading extracurricular books. I asked him to play in the playground. Gao said, "No, I have a class!" " "I had to give up and say," All right. "

Also, in high school, I pay great attention to the lectures and don't make small moves. Usually the composition is also very good. The composition is so neat that even the teacher often praises him! Usually I like to play ball, run and jump rope with him ... he plays great! High academic performance is so good that it is inseparable from his persistence in learning. Admirable!

Gao really loves studying. I want to learn from him and become such an excellent person.

3. Praise my classmate's 300-word composition in Grade Three.

There is a classmate named Xing Jingyan in our class. She has a pair of curved eyebrows, which bend like a crescent moon. There are watery eyes under her eyebrows, as big and round as black pearls. She also has a smooth mouth. Her skin is a little dark and she is a little short. She studies well and is especially helpful. One day in the third grade, I arrived at the classroom late, and she helped me to occupy a place. When I got to class, she warmly let me sit there. I skipped over and said to her, "Thank you."

She has a good temper, too. Once, I accidentally broke the pen she gave me. Xing Jingyan said, "Never mind, you don't have a pen. I'll lend you one!" "

Whenever I see her, she is absorbed in reading and doing her homework.

Once, I asked her to meet under a pine tree, but she didn't come down. I think: She loves studying so much that she may be painting or doing her homework upstairs. I found her doing her homework upstairs. I asked her, "Why don't you play?" She ignored me and continued to concentrate on her studies.

This is my classmate who loves learning and is helpful. She has many advantages and is worth learning.

She has long hair, round eyes and a small mouth, and her voice is a little hoarse. She is my good friend and my good classmate-Xie Yu. She is diligent and studious, and she is a good example to me.

She told me that if the desk was messy every day, she would tidy it up and clean it herself. As soon as I stepped into her room, it was clean

She doesn't often raise her hand to speak in class, but she sits up straight in class and listens to the teacher carefully.

She is also very helpful. Once, I played with her in the park and walked to the gate of the playground. I suddenly tripped over a small stone and was injured, but it was not serious. Xie Yuchong came over and asked me, "What's wrong with you? Are you all right? " "It hurts a little." I said in a trembling voice. At that time, she took out a band-aid from her mother's bag, and then she gently put it on me.

She is also smart and polite ... I must study hard from her.

5. Praise my classmate's 300-word composition in Grade Three.

She is my classmate and my good friend. She is Liu. She looks beautiful. Hair is long and smooth, like silk. Eyes are big, like two juicy grapes. That cute little mouth has a strong logic. Although her skin is a little dark, it looks very special.

She is an athlete. Although she is small, she jumps on the rope and flies over your head like a helicopter, with a clear voice. Once she ran a race with me, and she accidentally beat me, so I had to give her a reputation as a "lightning cheetah".

All that glitters is not books, and the sea is immeasurable. Although she is very young, her voice is very loud. Every class, she will answer questions, and the whole classroom is full of this sweet voice. Her voice is always in the morning reading class, and reading is also very emotional.

Her spirit of helping others is also amazing. I remember that once it rained, a classmate slipped in the stairwell. She ran over and almost fell, but she helped the man up safely and asked with concern, "Did you fall somewhere?"

She is beautiful and has a kind heart. How can I not praise her?

6. Praise my classmate's 300-word composition in Grade Three.

I have a good friend named Chen Sihan. She is tall with heavy eyebrows. She is a warm-hearted person. I remember once, we had to take an examination of philology. When the exam was about to begin, I found that I didn't bring my 2B pencil. "What should I do?" I'm as anxious as a cat on hot bricks. Chen Sihan saw that I was in a hurry and asked me, "Wang Nan, what's wrong with you?" I said, "No, I ate at school at noon and didn't bring my 2B pencil. How do I take the exam? " Without hesitation, she said, "Never mind, I have two. I will lend you one. " I'm relieved, thanks to Chen Sihan, otherwise I would have delayed the exam.

Another time, in the self-study class, I couldn't find my black pen anywhere, so I borrowed it from my classmates around me. As a result, they have nothing to spare. At this time, Chen Sihan saw me borrowing things everywhere and asked, "What did you forget to bring?" I said, "I forgot my black pen." Chen Sihan gave me one without saying anything, saying, "Here you are, idiot, you'll have to grow your brain next time." I said to Chen Sihan, "OK, thank you, friend!"

Chen Sihan is really a helpful knight. If there are more such people around me, the world will be better!

7. Praise my classmate's 300-word composition in Grade Three.

Speaking of Xiao Ming in our class, everyone knows. When he speaks, it is difficult to understand and he appears to be very knowledgeable. He has bright eyes and a glib mouth. He wears a pair of children's glasses and looks like a "little doctor".

Didn't Chairman Mao say a word: Modesty makes people progress, while pride makes people lag behind. Xiao Ming is like this. He is never proud, so he can get good grades every time. He is good at Chinese and math, which is attributed to his careful listening in class. In class, no matter what questions the teacher asks, he can always give the teacher a satisfactory answer. So we all think that Xiaoming is a worm in the teacher's stomach. This makes our classmates both envious and jealous.

He not only studies well, but also writes well. The teacher asked him to publish a blackboard newspaper. Look! How neat the words on the blackboard are, it is refreshing. I must try to catch up with him in the future!

This is my good friend Xiaoming, a little boy who loves to learn.

8. Praise my classmate's 300-word composition in Grade Three.

I have many classmates, among whom Xiaoming deserves praise. Xiaoming is a studious little boy. He has big bright eyes and black hair. He is almost as tall as me. When he smiles, he reveals a pair of lovely dimples.

He studies the most seriously in our class. Almost every subject is 100. Once, the teacher gave us a math paper and said, "This paper is very difficult, and it is not easy to get a score of 100." But he still got full marks. I watched him check the paper. No matter what was special next to him, he checked it as if he didn't hear anything. He is in a hurry. He checks every second. Therefore, even teachers can't find mistakes.

I remember once, I was thinking about an Olympic math problem. I racked my brains and thought hard, but I still couldn't figure it out. At this moment, Xiao Ming came over and said, "Hum! How come? Thinking about the Olympic math problem! " "Can you do that?" "Of course, let me tell you slowly: first add up the two numbers, and then get the number ..." In this way, Xiao Ming said it carefully several times until I understood it. I think: Xiaoming's quality of helping others is worth learning! In addition, I feel embarrassed that he wasted his playing time on teaching me Olympic Mathematics. Although this is only a trivial matter, Xiao Ming's excellent quality of helping others is vividly reflected.

Xiao Ming's good quality of helping others is admirable!
