Helen was the deaf and blind ,but she could overcome such difficulties from her teacher Sullivan’s help. For example, Sullivan tried to teach alphbets to her by writing them in her hands. As a result, Helen could start to write and speak at 10 years old. It is also because of her smartness and diligence. For instance, she entered the Light Hamerson school for the deaf and dumb in New York in 1894 ,and went to the Radcliffe University in 1900. Helen graduated from the university with honors. Besides, she devoted her life to the social service for the disabled people. For example, she spent money for the poor and had a fund-raising campaign to help the deaf-and-dumb.
