     Stephen Hawking was born in Oxford, England, in 1942. He went to school in St Albans. After leaving

school, Hawking went first to Oxford University where he studied physics, then he went on studying in

Cambridge University. As he himself admits (承认), he didn't work hard. He was a lazy student, and did

very little work. However, he still got good marks.

     At the age of 20, he first noticed something was wrong with him. His mother was very worried and

took him to see a doctor. He was sent to hospital for tests. He had an incurable (不可治愈的) illness. And

the doctor said he would die before he was 23.

     At first, he became very sad and disappointed (失望的). After coming out of the hospital, he suddenly

realized that life was beautiful. Later he married, found a job and had three children. He also went on with

some of the most important scientific research.

     Today, Hawking still works at Cambridge University as a professor. He strongly believes that his story
