What are the 700-word writers who write about 23 things?

Which two or three things make up a 700-word composition:

My brother is a middle school student. He has short black hair, a handsome face with bright eyes and a pair of arch eyebrows. As long as he is a math teacher who has taught his brother, there will be "math experts" who agree with him.

My brother can do not less than 100 multiple-choice math questions in five minutes, and the correct rate can reach over 90%. My brother has a quick mind and a flexible mind. Once, my father gave him several math problems with six-star difficulty, but after a period of thinking and verification by my brother, these problems were "defeated" in a short time, which I can't compare with.

My brother is still warm-hearted! I remember it was a winter night and we went out by bus. On this road, an old woman on the bus frowned, looked at the dark scene outside the window and kept mumbling: "Where is this?" Where is this? "

Seeing grandma's concern, my brother went up to her and asked, "Grandma, where are you getting off?" After grandma told my brother the specific location, my brother said without hesitation, "Oh, don't worry, I'll call you when I get there." Later, the grandmother said to her brother in a hoarse voice, "Thank you, young man."

My brother just smiled at the old woman and then sat back in his seat. I saw my brother staring at the front with focused eyes, afraid of missing it, which also enabled the grandmother to reach her destination accurately. My brother's professionalism is really worth learning! Actually, my brother is also a chess player. In our family, his chess skills are better, reaching an advanced level.

He often tells us: "Playing chess can cultivate sentiment, temper will and make people happy. We should play more chess. " The reason why he plays chess is that he likes playing chess and is good at learning chess. To be honest, my brother is one of my idols. He has the spirit I don't have and the agile thinking I don't have. I want to respect him.
