【简答题】
In a few decades, artificial intelligence (AI) will surpass many of the abilities that we believe make us special. This is a grand challenge for our age and it may require an “irrational” response. One of the most significant pieces of news from the US in early 2017 was the efforts of Google to make autonomous driving a reality. According to a report, Google’s self-driving cars clocked 1,023,330 krn, and required human intervention 124 times. That is one intervention about every 8,047 km of autonomous driving. But even more impressive is the progress in just a single year: human interventions fell from 0.8 times per thousand miles to 0.2, a 400% improvement. With such progress, Google’s cars will easily surpass my own driving ability later this year. Driving once seemed to be a very human skill. But we said that about chess, too. Then a computer beat the human world champion, repeatedly. The board game Go ( 围棋 ) took over from chess as a new test for human thinking in 2016, when a computer beat one of the world’s leading professional Go players. With computers conquering what used to be deeply human tasks, what will it mean in the future to be human? I worry about my six-year-old son. What will his place be in a world where machines beat us in one area after another? He’ll never calculate faster, never drive better, or even fly more safely. Actually, it all comes down to a fairly simple question: What’s so special about us? It can’t be skills like arithmetic, which machines already excel in. So far, machines have a pretty hard time emulating creativity, arbitrary enough not to be predicted by a computer, and yet more than simple randomness. Perhaps, if we continue to improve information-processing machines, we’ll soon have helpful rational assistants. So we must aim to complement the rationality of the machine, rather than to compete with it. If I'm right, we should foster a creative spirit because a dose of illogical creativity will complement the rationality of the machine. Unfortunately, however, our education system has not caught up to the approaching reality. Indeed, our schools and universities are structured to mould pupils to be mostly obedient servants of rationality, and to develop outdated skills in interacting with outdated machines. We need to help our children learn how to best work with smart computers to improve human decision-making. But most of all we need to keep the long-term perspective in mind: that even if computers will outsmart us, we can still be the most creative. Because if we aren’t, we won’t be providing much value in future ecosystems, and that may put in question the foundation for our existence.

【多选题】用分切镜头的方法表现一场戏或一件事的时候,摄像机要始终在轴线(关系轴线和方向轴线)的一侧安排拍摄角度,这对多方位的表现环境是一种限制。 为了多角度多方位的展现环境,多侧面地表现人物,总想越过轴线来表现"第四面墙",表现人物的位置的变化,近而获得多变的构 图形式。这时可以用越轴方法越过轴线进行拍摄 , 越轴的基本方法 有 ( )
A.
利用人物的运动改变原轴线形成新轴线。
B.
利用摄像机的运动(运动摄影)越过轴线
C.
中间插入无方向的中性镜头越过轴线
D.
利用人物出画入画越过轴线
