Great people play an important role in our life, and the greatest person in my heart is Stephen Hawking.
Stephen Hawking was a great scientist, who is famous for his work in physics. Although he lived most of his life in a wheelchair and had to speak with the help of a computer, he kept writing books, making speeches and doing research. He was also humorous. He could always tell people about physics in a simple and humorous way.
Stephen Hawking taught me to be brave. And when I face difficulties, I should never give up.
