材料一：清朝建都北京后，原居住于白山黑水间的各民族人口大量内迁，东北地区出现“沃野千里，有土无人”的状况。清廷把东北地区视为“龙兴之地”，在此设盛京。吉林、黑龙江将军，实施军事化管辖，设置关口，长期禁止关内人口迁居。往来须持有官方颁发的路票。“移民之居住有禁，田地之垦辟有禁，森林矿产之采伐有禁，人参东珠之掘捕有禁”。从乾隆年间开始，山东、河北等地“闯关东”者日盛，“每查办一次，辄增出新来流民”。他们“不但不肯回籍，抑且呼朋引类，日积日多”。清廷对东北地区时开时禁。

材料二：1689年的中俄《尼布楚条约》，划定了清朝与俄国的东段边界，但直至19世纪初，黑龙江以北数十万平方公里的土地上，居民不足1万人。第二次鸦片战争时，清政府被迫与俄国签订《瑷珲条约》和《北京条约》，清政府随即开放了哈尔滨以北的呼兰河平原和吉林西北平原。新来移民与当地满、蒙古等族通婚、建庙、演戏、立会、设学堂、建市镇。仅十余年，呼兰地区已是“三城相望，粮产富饶，商贾因之糜（群）集，流民居户不下十有余万”。1904年，清政府全面开放东北各边荒地；1907年，设奉天、吉林、黑龙江三省。1908年，仅奉天一省人口已达1100万人。1911年，清政府制定了东三省移民安边章程。

根据短文理解，选择正确答案。

    Claude Sammut,a professor of computer science and engineering at the University of New South Wales in Australia,said it would soon be possible for robots to defeat the stars of the future.

    For many years,Mr Sammut has been a member of a project called RoboCup,where robots have been programmed to learn how to play football and compete against others in a football match.

    As he explains,the robots are having difficulty in learning how to control the ball and move the ball on their own,but he is still full of confidence that one day in the future they will show the same skills as Wayne Rooney,who is one of the best football players in the world.

    Mr.Sammut also said,"In 1968,John McCarthy and Donald Michie made a bet with David Levy,who was then the chess champion in Scotland,that within 10 years a computer program would be able to beat him.It took a little bit longer than 10 years (nearly 30 years) but eventually such programs came into being."

    "In the same spirit of a grand challenge,RoboCup aims to develop a team of robots that can defeat the world soccer champion team by the year 2050.To achieve this,or come even closer to the ambition,the robots will have to be able to sense and act in completely unstructured environments.This will require major advances in perception（感知）,decision making,learning,and cooperative behaviors.Considering robots are integrated hardware and software systems,great advances will also be needed in sensors（传感器）,energy storage,and materials."
