It's in Hawking's wheelchair in lesson 10 of the first volume of the sixth grade Chinese of the Soviet Education Edition. 1963, 2 1 year-old, unfortunately suffered from Luger's disease when he was a graduate student at Cambridge University, which would lead to muscle atrophy. Soon he was completely paralyzed and confined to a wheelchair for a long time. From 65438 to 0985, Hawking underwent tracheal puncture for pneumonia and completely lost the function of speaking. After 40 years, Hawking's head can only tilt to the right, his shoulders are low on the left and high on the right, his hands are tight in the middle, he holds a palm-sized mimetic keyboard, his feet are twisted inward, and his mouth becomes S-shaped. It's hard. The doctor said he could only live for two years, but he didn't die and didn't complain. He worked, studied and lived normally ... so he was awarded the title of "giant of science" and "king of the universe". Hawking's charm lies not only in his legendary physical genius, but also in his convincing life force. His famous saying is "If life is not fun, it will be a tragedy." "There is hope when you are alive." ......
