【題目】 World famous physicist(物理學家)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 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(音響合成器)“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.
