You are twenty-one years old and have a good life. But one day, your doctor tells you that you have a bad disease and may not live more than one year. How would you feel? What would you do? I think most of us might feel very sad and give up our dreams and hopes for the future. Here is what the great scientist, Stephen Hawking, did.
    Hawking didn’t let the disease stop him from living the kind of life he had always dreamed of. He went on with his study of the universe and traveled around the world to give talks. In 2002, Hawking visited China and spoke to uni versity students in Hangzhou and Beijing. Because of the disease, Hawking had to sit in his wheelchair and speak through a computer. He told the students about his theories(理论) on some of the greatest questions: what is time, how did the universe begin, and what are black holes.
    Hawking became famous in the early 1970s. In 1988, he wrote A Brief History of Time. The book explains difficult theories in a simple way and it sells very well.
    Stephen Hawking is a man with a strong will and he is regarded as the greatest mind in physics since Albert Einstein.
