    My friend Lin Tao was born in Liaoning Province to the northeast of China. He met with a traffic accident when he was younger. As a result, he lost one of his legs. Although he suffered a great deal, he never loses his heart. Lin Tao has been published a book. He enjoys playing his guitar and listen to music. He does excellent job in school. But he is always ready to help those in trouble. He wins the respects of his classmates and his teachers.

    In my opinion, Lin Tao is extreme brave and he sets a good example to we all.
