Suddenly I looked up and saw a pair of butterflies flying through the window. Delicate butterflies are dancing lightly among the flowers in pairs. Their tails are as long as ribbons, fluttering in the wind under the clear sky, and their dancing posture is very beautiful.

Seeing butterflies in pairs reminds me of our sisterhood. It is this beautiful butterfly that illustrates the beauty of symmetry and our friendship.

"Alas, this function is so strange that I can't find the symmetry axis that the teacher said. It's too difficult ... "I looked at my exercise book stupefied, chanting" tossing and turning "in my mouth.

"hmm? Let me see ... it's not difficult! You see this parabola is on a rectangular coordinate system ... "At the same table, you explained the most basic functional knowledge in professional terms, but I was confused when listening to you draw three draft papers, and finally shook my head with inferiority.

At that moment, I had a little more aversion to ugly functions, and I resisted from the heart. I heard you were in another world? Scattered echo: "It doesn't matter! I'll explain it to you tomorrow ... "

These paragraphs are the foreshadowing of the following plot, so it is unnecessary to be so long. Can be condensed into a paragraph or even a sentence)

The wind blowing through the graduates in June is restless, and the tired sound of reading is even weaker with the accompaniment of the "creaking" fan. In such an environment, those knowledge points become more and more troublesome.

"ah! Dear, good thing! " I put down my book and saw you come into the classroom in the morning light, smiling at me and saying. I can't help but ask curiously, "What is it?"

You take out a picture book from your schoolbag and open it with a smile: butterflies flying in pairs fly leisurely in the air, and delicate reflections appear on the sparkling water, playing with the fish in the water. There is a poem beside the painting: "hawthorn trees on the river are fragrant, and butterflies fly on the shore." Zhulou is connected with water, and the sand warms a pair of fish. "

"Well, look! Every butterfly's wings are symmetrical, so are two butterflies if they fly together, the reflection in the water and the butterfly itself are also symmetrical, and the two sides of the quadratic parabola symmetry axis are also symmetrical ... "You said with a smile.

I suddenly understand the concept of symmetry. You are smart enough to interpret the beauty of life and mathematics with works of art, so vivid and beautiful! It turns out that parabola is not as annoying as I thought. It turns out that math problems are not as annoying as anxiety. It turns out that all this is so symmetrical and beautiful.

At this moment, I finally understood what symmetry is. I looked up and smiled at you, only to find two butterflies flying dramatically! "Look!" My name is, our eyes focused on those two butterflies, with the symmetrical beauty we found, flying away, flying away. ...

The main idea of the article is to show the beauty of friendship, but the focus is on symmetrical butterflies, turning virtual into real, vivid and natural images. It also focuses on the symmetry of butterfly wings to write friendship, which has both reality and reality, clear clues and good results. Coupled with a deep language foundation, I can see at a glance that my writing skills are not shallow.

But judging from the semi-propositional topic "At this moment, I found it", your article is not ideal. The main reasons are:

1, the "this moment" in the title, you reflected it from the beginning, but "this moment" is mediocre and nothing strange-can you focus on a strange "this moment", that is, focus on an abnormal moment (celebrities like the moment of life or death, the moment of love and hate changing, the moment of leaving, the moment of accident, etc.). )?

2. After focusing on the unusual "this moment", we should combine the strange people, things, objects and scenes to express this profound and strange feeling and theme. But your article is thin, so I wrote that my good friend helped you find the symmetry axis. Although it is beautiful in combination with the reality of butterflies, it is not important (girls' articles are so light and beautiful, lacking thinking and reflection on life, life, society, nature and history. And the high school boys' articles are magnificent, thick, open and expressive. Then, can you combine the atmosphere with strange events, that is, strange people and things, to express the main idea? (Can and must be fictional)

3. The main idea is to show friendship, but can it be a bigger friendship? Can this small friendship be compared with the friendship under the background of country, society and life? After all, there is a difference between a small jasper and a good family. The composition written in the college entrance examination and important moments in life should be atmospheric. Otherwise, how can we select talents with great atmosphere? So your friendship theme is a little higher and deeper?

In a word, the technique of this article is wonderful, but the theme and content are mediocre. Please forgive me for the inappropriate place.

In addition, I hope you will pay attention to the above words when writing this senior high school entrance examination. The composition of the senior high school entrance examination also distinguishes the advantages and disadvantages from the depth of the theme, the mediocrity and superficiality of the content, and the poverty and strangeness of the skills. Whether this year's senior high school entrance examination in Shenzhen is about affection, friendship, nostalgia or life, life, society and nature, please establish a profound theme and choose strange and heavy materials and wonderful skills.
