This book moved me very much. Helen Keller is really brave! In such difficult circumstances, she still persisted in studying and never gave up her love for life. I particularly disliked Helen's teacher Sullivan. She was so cruel to Helen at first, but later she understood Helen's difficulties and became Helen's good friend. Her words, "Knowledge is love and light, it can lead people to heaven," impressed me deeply. This book is full of hope and strength and worth reading!

It's very good that I finished reading it, but I didn't take a good look at the letter.
