       海伦 凯勒，出生后不久不幸患病，两耳失聪，双目失明。在莎莉文老师的帮助下，海伦学会了说话和书写，就读于马萨诸塞州剑桥女子学校，后又进入哈佛大学，1904年以优异成绩毕业。她致力于为残疾人造福，建立慈善机构，被美国《时代周刊》评为美国十大英雄偶像，荣获“总统自由勋章”等奖项。

       I HAD NOW the key to all language, and I was eager to learn to use it. Children who hear acquire language without any particular effort; the words that fall from others’ lips they catch on the wing, as it were, delightedly, while the little deaf child must trap them by a slow and often painful process. But whatever the process, the result is wonderful. Gradually from naming an object we advance step by step until we have traversed the vast distance between our first stammered syllable and the sweep of thought in a line of Shakespeare.
       At first, when my teacher told me about a new thing I asked very few questions. My ideas were vague, and my vocabulary was inadequate; but as my knowledge of things grew, and I learned more and more words, my field of inquiry broadened, and I would return again and again to the same subject, eager for further information. Sometimes a new word revived an image that some earlier experience had engraved on my brain.
       I remember the morning that I first asked the meaning of the word, ‘love.' This was before I knew many words. I had found a few early violets in the garden and brought them to my teacher. She tried to kiss me; but at that time I did not like to have any one kiss me except my mother. Miss Sullivan put her arm gently round me and spelled into my hand, ‘I love Helen.'
‘What is love?' I asked.
       She drew me closer to her and said, ‘It is here,' pointing to my heart, whose beats I was conscious of for the first time. Her words puzzled me very much because I did not then understand anything unless I touched it.
