When Helen was seven years old, her parents invited a specially trained Sullivan teacher from other places. Helen Keller learned to read from Sullivan.

The story of Helen Keller:

Helen Keller is a famous American writer and educator. 1882, when she was over one year old, her brain was injured because of a high fever. From then on, her eyes couldn't see and her ears couldn't hear. Later, she couldn't even speak. She grew up groping in the dark. At the age of seven, the family hired a tutor for her, that is, Miss Sullivan, who influenced Helen's life.

Sullivan was almost blind when he was a child, and he knew the pain of losing sight. Under the guidance of her efforts, Helen learned sign language by touching hands, reading by touching some cards, and finally learning to speak by touching others' lips. In order to get Helen close to nature, Miss Sullivan asked her to roll on the grass, run and jump in the fields, sow seeds in the fields and climb trees to eat.

I also took her to touch the newborn pig and go to the river to play with water. Under the careful care of the teacher, Helen overcame the obstacles of blindness and deafness and completed her college studies.
