A passage that describes a classmate s serious thinking

In class, the teacher always throws out a lot of questions for us to answer. Some of these problems are easy and some are complex, and for some easy topics, many students often rush to raise their hands, but whenever they encounter those problems, everyone is silent, and they dare not raise their hands easily. But whenever our classroom fell into a dull place, in the last row of our class, there would always be a hand raised high, and he was Kevin Zheng.

I remember once in math class, the teacher came up with a thinking problem, and asked everyone to calculate it in a simple way: 49+48+......The answer to 1. After reading it, the students scratched their ears and cheeks and thought about it, and some students didn't do it when they saw it.

But Zheng Kaiwen sat there for a while holding his chin with his hand and thinking quietly, and then picked up the pen again, concentrating on calculating, and soon he jumped up excitedly and said, "I made it!" I've made it!

So the teacher asked him to come to the podium and explain it to everyone. I saw him pick up the chalk and write ...... on the first lineOn the second line is written ......Then, with a smile on his face, he began his explanation. After listening to his analysis, it dawned on us.

Kevin Cheng not only thinks actively and speaks enthusiastically in mathematics class, but also performs equally well in Chinese class. In Chinese class, whenever Mr. Wu asks a difficult question, you can often see him frowning, holding the pen tightly in his right hand, drawing in circles on the book, and finally raising his hand confidently, and then starting to analyze reasonably. Sometimes I would debate with Mr. Wu.

Mr. Wu also often said that the reason why Zheng Kaiwen was able to take the first place in the final exam of Chinese was because he was good at thinking.

Kevin Zheng, he just loves to think so much, this is his biggest characteristic.

In the classroom, some were talking, some were fighting, and some were shouting, and she was so engrossed in the calculation that she seemed to have forgotten everything around her. Sometimes she bites the tip of her pencil and thinks about problems, sometimes she frowns because she can't think of an answer, and sometimes she is ecstatic that she has done it.

I saw him moving forward for a while, backward for a while, brushing here for a while, brushing for a moment to support his classmates, and for a moment the paper hand kept waving around.

1) In the Chinese class, the student sat upright on the chair, listening attentively, the pen in his hand swayed from time to time, and the model was simply recording something, which was really gratifying.

2) In the Chinese class, the students sat on the chairs, their faces were clean, their hands and pants were on the table, they were upright, like the sunflowers, positive and studying hard.
