Stephen Hawking was one of the most famous scientists in this century. He was born in 1942. He's a world well-known on space and time. Stephen is researching some very big questions, such as: How did the universe begin? How will it end?

Stephen was a student at Oxford University. He studied math and science. Then, at the age of twenty, he became sick. He was so young, but the doctors said to his family, “He has only two more years to live.” As a matter of fact, the doctors were wrong—- he didn't die. He can't walk now but he uses a wheelchair(轮椅). He can't feed himself and get in or out of bed himself. But he refused to give in to the condition. He talks with the help of a computer. After Oxford, Stephen went to Cambridge University. Three years later, in 1965, he became a doctor of philosophy(哲学).

    Because of his serious health problems, it was difficult for him to draw diagrams(图表)or to write. So he started to think in pictures. With this new way of thinking, he became one of the most famous scientists in the world. In 1991, he met the Pope(教皇) in Rome. They talked about his ideas. Then in 1998, he wrote his first important book, A Brief History of Time. It sold more than 5.5 million copies in 33 different languages. He was once invited to China, he impressed us with his self-confidence, humorous and witty(风趣的) conversation.

    Growing up in the US, I always wanted to know about another culture. The chance came when I was 15. After a few months of planning and preparing, I was ready to spend the second term of my first year of high school as an exchange student in Australia.

    The city I stayed in was Perth, Australia, and it is the fourth largest city of Australia. When I arrived at the airport, the family I would live with were already waiting for me there, and the new school term would start in only five days. The school I attended was very different from my school in the US. In the school we had to wear the uniform, and we were not allowed to wear bracelets (手链) or necklaces(项链). I was quite uncomfortable at first, because I had never been to a new school— even in the US. Everything went smoothly, though. The teachers were welcoming and the students were friendly.

    The most memorable time of my term abroad was with other international exchange students. We traveled around Australia during the breaks. The few weeks we spent together were filled with amazing activities. At the end of our stay in Australia, we had three weeks to share our stories and help each other. Our last day together was filled with tears. We packed our things, exchanged e-mail addresses, and got together to say goodbye.

    I really have learned a lot from my exchange experience.

School started again, and soon the ink(墨水)in Tom's spelling book was found. Tom said he hadn't split the ink, but that made it look as if he were lying. Becky almost said Alfred Temple had done it, but she kept quiet. She thought that Tom would tell the teacher about her tearing(撕)his book, so she didn't save him. Mr Dobbins beat him and then Tom went back to his seat。

After an hour Mr Dobbins unlocked his desk and took out his book, Tom looked over at Becky. She looked like a hunted and helpless rabbit. The next moment the master faced the children. There was a long silence, then he spoke, "Who tore this book?"

There wasn't a sound. The teacher searched their faces.

"Benjamin Rogers, did you do it?"

Benjamin said no.

"Joseph Harper, did you?"

Joseph also said no. Dobbins looked at the rows of boys, thought for a moment, then turned to the girls.

"Amy Lawrence?"

A shake of the head.

"Gracie Miller?"

The same sign.

Becky was next. Tom was shaking from head to foot.

"Rebecca Thatcher?"—(Tom looked at her face; it was white with terror)— "did you tear?—no, look at my face—did you tear this book?"

Tom jumped to his feet and shouted, "I did it!"

The children stared(盯着) in surprise at his foolish act.

And when he stepped forward for his punishment, he saw the surprise, the thanks, and the love that came from Becky's eyes.This was enough for one hundred beatings. And he didn't even mind staying for two hours after school, because he knew that Becky was waiting for him outside.

Tom went to bed that night planning some actions on Alfred Temple, for Becky had told him everything. And he fell asleep with Becky's last words to him in his ear, "Tom, you are so great!"
