The last self-study class, the campus is quiet, twinkling stars set in the black sky. The bright classroom is very quiet, and only the sound of "brush" can be heard. Slowly, the politics teacher came in with a kind smile, and his clear voice echoed in the quiet classroom: "The exam is coming tomorrow, so prepare for it, and ask some simple questions first." Instantly, the quiet classroom heard the sound of "Hua Hua" turning over a book, "Buzz" reciting questions, and the whole classroom suddenly became nervous.

Xiao'an turned to page 20, the most auspicious page in her opinion, and mysteriously took out a brand new coin from the stationery box. Her heart began to beat wildly, her face turned red, her eyes stared at the coin, stared at it for a moment, and then shook the coin in her hand: "The number is no question, the national emblem is a question." When she thought it was the best time, she opened her hand: "The number!" The hanging heart finally landed safely. Xiaolin, the deskmate, was startled by Xiao'an's low cry and looked at her in surprise.

Five minutes later, the classroom became quiet and the teacher began to ask questions. "Classmate x" the political teacher was shouting. "Ah, it's my turn to look at me one more time. I will never be asked today. The angel has already told me." Xiao'an tried to calm herself down, and she felt lucky. After school, Xiao'an was about to leave when Xiaolin asked her, "Xiao'an, what did you do before the political teacher asked today. "Oh -" Xiaolin's eyes rolled and his voice lengthened.?

The next day, in English class, the teacher said to dictate words, and asked one of the students to go to the blackboard to write from memory. Xiao'an opened the stationery box and was about to pick up the coin, only to find a note beside the coin, which said:

Xiaoan: The words for today's dictation are: wear, out

——Letter from Angel

Xiao'an wondered: Who is joking with me? She smiled, looked around, and found nothing special. "Wang Xiao'an, go up and write from memory!" the teacher was laughing. Xiao'an was uneasy and chose the most auspicious piece of chalk from a dozen pieces. "Wear, out..." the teacher read. God! It's the same as the note! Xiao'an walked down the platform like a cloud, and she felt as if a pair of eyes were watching her. She felt extremely happy because someone helped her silently in the dark. In a class, Xiao'an took out the note for many times. The beautiful handwriting seems familiar, but he is not very sure.

After class, Xiaolin asked Xiao'an: "Xiao'an, what was she doing with a note in class? It was so mysterious?" Xiao'an seemed very relaxed: "Nothing, just a note to remember English words." "Not like her." She said in her heart. And she knows Xiaolin's character. It should not be her.

Since then, the "angel" has told Xiao'an in advance all the questions and dictations that the teacher has to ask in class. Xiao'an has read and recited them before class, and prepared carefully. Most of the questions in class are Xiao'an's share, and they are praised every time. She felt extremely happy. After two weeks of this, Xiao'an no longer has the coin in his stationery box. Instead, there are letters from angels.

Gradually, Xiao'an's achievements began to rise, and she was able to compete with Xiaolin. Xiao'an had been trying to find someone to help her, but there was no clue at all.

Finally, in the fifth week, what was written on the note was no longer a question, but a sentence:?

Xiao'an, congratulations. Your study has improved. More importantly, you have got rid of coins. Since then, there will be no more notes.

——People who care about you

"People who care about you"! Xiao'an thought of her father, mother, teacher, and... She said in her heart: "Care - Angel, thank you! Your care is my happiness in my life!"
