20、ng a banana juice as a reward when he playedthe game correctly.Soon Pager was eager to play well in order to get more smoothie.At first,Pager controlled the video game using a joystick(操纵杆).But as Pager played,his Link devices wirelessly sent out information about the signals his brain was using to

21、control his arms and hands.Neuralinks scientists recorded all of these signals.Then they used computers to match up the signals from Pagers brain to the movements that his hands were actually doing.This was challenging work and the scientists counted on artificial intelligence(AI)to help them decode

22、(解码)Pagers brain signals.The next step was to have a computer make moves in the video game as if Pager had actually moved the joystick.If Pager thought about moving the joystick up,the computer would send an upsignal to the video game.Thus Pager was able to play the video game using just his brain.W

26、right Future C.Monkey Plays Video Games with His Mind D.Neuralink,a Creative and Competitive Company D One billion people in the world are short of water.How can this problem be solved.Some suggestions have been to desalinate ocean water or to build enormous water pipelines from areas where water is

27、 abundant.(Suggestions such as these prove extremely expensive when they are actually used.)One possibility that scientists are considering is pulling icebergs from either the North Pole or the South Pole to parts of the world with a water shortage.Although many questions must be answered before suc

28、h a project could be tried,moving icebergs seems a reasonable possibility in the future.Engineers,mathematicians,and glaciologists from a dozen countries have been considering the iceberg as a future source of water.Saudi Arabia is particularly interested in this project because it has a great water

29、 shortage.Scientists estimate that it would take 128 days to transport a large iceberg(about 1/2 square mile)to Saudi Arabia.Yet the iceberg would be completely melted by the 104th day.Therefore,insulation would be essential,but how to insulate the iceberg remains an unsolved problem.The problems in

30、 transporting an iceberg are numerous.The first problem is choosing the iceberg to pull.The icebergs that form in the North Pole are quite difficult to handle because of their shape.Only a small portion extends above the water most of the iceberg is below the surface,which would make it difficult to

31、 pull.South Pole icebergs,on the other hand,are flat and float like table tops.Thus they would be much easier to move.How can a 200-million-ton iceberg be moved.No ship is strong enough to pull such enormous weight through the water.Perhaps several ships could be used.Attaching ropes to an iceberg t

32、his size is also an enormous problem.Engineers think that large nails or long metal rods could be driven into the ice.What would happen if the iceberg splits into several pieces during the pulling.Even if an iceberg with very few cracks were chosen,how could it be pulled through stormy waters.Furthe

33、rmore,once the iceberg reached its destination,very few ports would be deep enough to store it.All of these problems must be solved before icebergs can become a reasonable source of water.Yet scientists estimate that it will be possible to transport them in the near future.Each year,enough icebergs

34、form to supply the whole world with fresh water for a full year.In addition,icebergs are free and nonpolluting.As a solution to the worlds water problems,icebergs may be a workable possibility.12.What is a problem in transporting iceberg?A.The size of the iceberg.B.The colour of the iceberg.C.The sa
