     One of the most famous basketball players in the New Castle ' s history was paralyzed(瘫痪的) in a wheelchair one day and was walking the next. Citizens of New Castle simply refer   to it as  " The Miracle" .

Joel Haler woke up in his dorm room at Hope College last October totally paralyzed from  the waist down. Four hospitals later, the only way he could walk was through Robotic Walking  Treatment.

"This past Tuesday ,I was doing the Robotic walk and lasted ten minutes, " Joel said. After that, he gave up. Joel w-anted to accept the  inevitable (不可避免的事)  and  cancelled his next Robotic Walking Treatment appointment.

Then , the night before his cancelled appointment, he woke up to a terrible pain. An hour  and a half later ,the serious pain left him with an unusual feeling in his legs.

" As it continued to move up my legs ,it became more and more painful and it took an hour  and a half to reach my hips(臀部) , " Joel recalled.

"I stood up and walked into my parents'  room. ' Mom and dad, look! ' ," he said proudly.

" He said something and I was like, ' Joell Joel !  You ' re walking !  You ' re walking ! '  We  jumped out of bed , cried and hugged, "  Joel ' s mom  Karen remembered.

"I burst into tears. It ' s hard seeing your son not be able to walk .but he was standing there , walking , "  Joel ' s  father  Eric  said , tearfully.

It was Thursday , January 23 , when he  could finally  walk. That  date  made  perfect  sense  to Joel. He had dreamt of a calendar that only said "J 23 " . He didn't know what to make of it until "a little boy at church ,four years old, came up to me and said, ' you will walk on a Thurs-day ' , "  Joel recalled. 

So the 20-year-old college student, who could only walk with the aid of a robot on Tuesday ,was walking on his own.
