In order to avoid verbosity and highlight the theme, the selection of materials must be cut, not comprehensive, and transitional words or sentences should be used to make the connection between paragraphs more natural.

The model essay is as follows:

My name is Guo Jiaqi, and I am now in Grade One of Gaoxin No.1 Middle School in Yulin City, Shaanxi Province. I am 16 years old this year. There are three people in my family, including my father, my mother and me. I am not handsome, but I am not ugly. There are a pair of heavy eyebrows on the round face, two big ears on both sides, a nose embedded in the center of the face and a small mouth under the nose. I smile every day, even if I have troubles, I won't say it.

I used to be a little fat man, but since I fell in love with sports, I have become very healthy. As long as I finish my homework every day, I will go out to run and play basketball. If it rains, I will do your sit-ups and other physical training at home and practice street dance on weekends.

I, sometimes, am careless. Take mathematics for example: 125×30=3750. The simple method is 125×3=375. I use this method to calculate the result first, directly regard "375" as a number, and reduce the product by 10 times. Sometimes, I will treat addition as multiplication and multiplication as addition!

I finished my homework and didn't check it at all, which caused many mistakes. If I check, sometimes I will copy it again according to the original text. To save your brain, of course. I decided to check my homework carefully in the future to make sure there are no mistakes.

I like listening to music. Sometimes, I also listen to music when I eat and when I do my homework. At first I thought it was killing two birds with one stone, but on second thought, I still didn't do anything well. I think: I will watch less TV and concentrate on my studies in the future.

I have many advantages and many disadvantages. I will correct these shortcomings in the future, learn from others' strengths and make up for my own shortcomings. I want to change myself and be a brand new me.
