我想,对于像你这样的小小科学迷来说,“斯蒂芬·霍金”这个名字一定不陌生吧?这位英国剑桥大学的物理学教授、世界著名物理学家,在21岁时不幸患上了一种会使肌肉萎缩的疾病。疾病使他的身体严重变形,最终仅剩三根手指能够活动,不得不依靠轮椅进行日常活动。起初,医生断言他只剩两年的生命,可是他如今已经73岁了,仍然致力于科学研究工作,并在世界各地演讲。你一定注意到了他轮椅上配备的电脑,每次说话时,他的嘴巴都没有动,而是电脑发出了声音。可是,电脑是怎么知道他要说什么的呢? I think for a small science fan like you, “Stephen Hawking,” the name must not be unfamiliar? The professor of physics at the University of Cambridge, the world-renowned physicist, at the age of 21, unfortunately Suffering from a disease that causes muscle atrophy. The disease deforms his body so severely that eventually only three fingers can move and have to rely on wheelchairs for daily activities. At first, the doctor asserted that he had only two years left, but he is now 73 and remains committed to scientific research and giving lectures around the world. You must have noticed his computer equipped with a wheelchair, and his mouth did not move each time he spoke, but the computer made a sound. However, how does the computer know what he wants to say?
