【题目】 World famous physicist(物理学家)Stephen Hawking died peacefully at his home in Cambridge on March 14th, 2018.

Hawking was born in Oxford, England on January 8th, 1942. He went to school in a small city near London. As he himself admitted, he wasn't very serious about studying. He did very little work, he was never top of his class. However, he still achieved good marks. After leaving school, Hawking first went to Oxford University to study physics. Then he went to Cambridge University to study cosmology(宇宙学)

At the age of 21, Hawking noticed something wrong with him. He had a bad illness that stopped him from moving and talking. He couldn't communicate except by blinking(眨眼). He sat on a wheelchair with a computer by his side. To communicate with others, he moved two fingers to control the computer's mouse. He chose his words from the screen, which were then spoken by a voice synthesizer(音响合成器)“I've had the disease for most of my life”Hawking once said“Yet it has not stopped me from being successful at my work.”

Although Hawking was a disabled man, he made great achievements. He received many awards and prizes for his work, including the Albert Einstein Award—the highest achievement in physics.

Hawking worked at Cambridge University as a professor. His story shows that nobody, however bad their situation is, should lose hope. “Life is not fair”he once said“You just have to do the best you can in your own situation.”
