1、 A computer program has beaten a human champion at the ancient Chinese board game Go. It marked an important advance for the ①__________(develop) of artificial intelligence. The program,②__________(call )AlphaGo, had taught itself how to win. It beat the European champion in all five games of a match in October. The developers say ③__________(it) learning ability may someday let computers help solve real-world problems. Those could include making medical diagnoses and ④__________(conduct)scientific research.
Previously computers have beaten humans in other ⑤__________(game).But among classic games,Go has long been viewed as the most challenging for artificial intelligence to master.
Go originated in China more than 2,500 years ago.⑥__________game involves two players who take turns putting markers on a checkerboard ­ like grid.

The rules are simple,⑧__________playing it is not. It's probably the most complex game ever created by humans.
Martin Mueller,a computing science professor,⑨__________(work) on Go programs for 30 years. He said,“The new program is really a big step up from everything else ⑩__________we've seen. It's a very impressive piece of work.”
