Stephen William Hawking (born on January 8, 1942) is an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge. As a child, he was enthusiastic about{#blank#}1{#/blank#}(design) complicated toys but {#blank#}2{#/blank#} (unfortunate), in his twenties, he suffered{#blank#}3{#/blank#}a disease that couldn't be cured,{#blank#}4{#/blank#}was a great challenge for him. As the condition {#blank#}5{#/blank#}(progress) over the years, finally he became almost entirely paralysed (瘫痪的) and could only communicate through a speech generating device. However, not only was he positive about the misfortunes, but he also eventually defeated all the {#blank#}6{#/blank#} (obstacle) and became {#blank#}7{#/blank#} (absorb) in his research into the universe. In 1988, his best-seller A Brief History of Time{#blank#}8{#/blank#}(publish), in which he put forward the idea that time{#blank#}9{#/blank#}(it) has a beginning, and that it will have an end. This book stayed on the British Sunday Times best-seller list for a record-breaking 237 weeks. In{#blank#}10{#/blank#} (conclude), he has made outstanding contributions to the fields of cosmology and quantum gravity.

    The story happened in ancient times. A king was so clever that he thought of a good way to test {#blank#}1{#/blank#} his men were reliable.

    One day, he had a huge rock {#blank#}2{#/blank#} (place) on a roadway at night. Then he hid {#blank#}3{#/blank#} (him) nearby and watched carefully to see if anyone would remove the big rock. Some {#blank#}4{#/blank#} (wealth) businessmen and high officials came by, but they simply walked around it. Many of them even loudly blamed the king for not keeping the roads clear, but none of them would bother {#blank#}5{#/blank#} (get) the big stone out of the way.

    Then a villager came along carrying a load of vegetables. On {#blank#}6{#/blank#} (approach) the big rock, he stopped and laid down his burden, trying hard to move the stone to the side of the road. After much pushing, he {#blank#}7{#/blank#} (final) succeeded. As the villager picked up his load of vegetables, he noticed a purse lying in the road where the rock {#blank#}8{#/blank#} (be). The purse contained many gold coins and a note from the king, saying that the gold was for the person {#blank#}9{#/blank#} removed the huge rock from the road.

    The villager learned a valuable lesson that many others would never understand: Every obstacle presents {#blank#}10{#/blank#} opportunity to improve one's condition.

    China's first artificial intelligence (Al) textbook for high school students {#blank#}1{#/blank#}(bring) out last week, following a plan by central government {#blank#}2{#/blank#}(include) Al courses in primary and secondary school.

    The nine - chapter textbook, {#blank#}3{#/blank#}(name) " Fundamentals of Artificial Intelligence" , was written by outstanding {#blank#}4{#/blank#}(scholar) from well - known schools nationwide, under the joint efforts by the research center for MOOC at East China Normal University and Al startup SenseTime. It includes the history of Al and how the technology can be applied in areas such as facial recognition, auto driving and public security.

    "The textbook focuses not only on basics of Al, but on {#blank#}5{#/blank#}(practice) use of Al in daily life," said Chen Yukun, a professor at East China Normal University, {#blank#}6{#/blank#} is also a contributor to the book.

    Up till now, about 40 high schools across the country {#blank#}7{#/blank#}(undertake) the task of being the first group of Al high education pilot program {#blank#}8{#/blank#} introducing the textbook in the curriculum. "The Al sector is facing a talent shortage {#blank#}9{#/blank#}(global). The publication of the book is {#blank#}10{#/blank#}breakthrough as it takes Al technology out of the 'Ivory tower' and makes it part of high school learning," said Lin Dahua, a professor at the Chinese University of Hong Kong.
