Teacher, the purpose of this letter is to introduce a book that my mother bought for me. Its name is "Legend under the Apple Tree-Newton".

This book focuses on Newton's life experience and achievements. He is a famous British physicist, mathematician and astronomer. Among them, there is a story that amazed me. The story is that Newton discovered the mystery of gravity. That day, 23-year-old Newton was sitting under an apple tree reading a book. Looking intently, an sour and astringent apple fell down and landed right on Newton's head. It was this apple that made Newton think of a question: Why does the apple have to fall? Instead of left, right and up? So Newton took this question to his alma mater, Cambridge University. He asked the students and teachers, but no one could explain it clearly. Finally, it took Newton two years and more than 400 experiments to explain the problem of gravity to the world.

This story reminds me of the experience of learning to ride a bike a few years ago. At first, I was full of confidence, but as soon as my mother let go, my bike couldn't control itself and swayed like a drunk. The result of the story development: a dog fell on the mud! I grazed my knee and blood leaked out. It hurts! I can't describe it! I really want to cry! Seeing this situation, my mother rushed over and said with distress, "Son, why did you fall?" Does it hurt? Ouch, the skin is broken, so we won't learn! Don't learn! "When I heard my mother say this, I pretended to be okay and said," Mom, it's okay! I won't give up even if I break my hands and feet! " Mother gave a thumbs-up and said, "Well done! Then let's continue! "After countless failures, I finally learned to ride a bike! Compared with Newton, I think I also have his persistent spirit.

Teacher, there are many wonderful contents in this book, such as Newton's hardships in getting into Cambridge and so on. This book not only records many things about Newton, but also some beautiful paragraphs, so I really hope the teacher can read this book.

Wish you all the best.

Good health and smooth work!
