第二篇Download Knowledge Directly to Your BrainFor the first time,researchers have been able to hack into the process of learning in the biain,using induced brain patterns to create a learned behavior. It's not quite as advanced as an instant Kung-fu down- load,and it's not as sleek as cognitive inception,but it's still an important finding that could lead to new teaching and rehabilitation techniques.Future therapies could decode the brain activity patterns of an athlete or a musician,and use them as a benchmark for teaching another person a new activity,according to the researchers.Scientists from Boston University and ATR Computational Neuroscience Laboratories in Kyoto used functional magnetic resonance imaging,or fMRI,to study the learning process.They were examining the adult brain's aptitude for visual perceptual learning,or VPL,in which repetitive training improves a per- son's performance on a particular task.Whether adults can do this as well as young people has been an on- going debate in neuroscience.Led by BU neuroscientist Takeo Watanabe,researchers used a method called decoded fMRI neurofeed- back to stimulate the visual cortex.First they showed participants circles at different orientations.Then they used fMRI to watch the participants'brain activity.The researchers were then able to train the participants to recreate this visual cortex activity.The volunteers were again placed in MRI machines and asked to visualize shapes of certain colors.The participants were asked to"somehow regulate activity in the posterior part of the brain"to make a solid green disc as large as they could.They were told they would get a paid bonus proportional to the size of this disc, but they weren't told anything about what the disc meant.The researchers watched the participants'brain activity and monitored the activation patterns in their visual cortices."Participants can be trained to control the overall mean activation of an entire brain region,"the study authors write,"or the adtivation in one region relative to that in another region."This worked even when test subjects were not aware of what they were learning,the researchers said."The most surprising thing in this study is that mere inductions of neural activation patterns corresponding to a specific visual feature led to visual performance improvement on the visual feature,without presenting the fea- ture or subjects' awareness of what was to be learned,"Watanabe said in a statement.Watanabe and colleagues said this method can be a powerful tool."It can'incept' a person to acquire new learning, skills,or memory,or possibly to restore skills or knowledge that has been damaged through accident,disease,or aging,without a person's awareness of what is learned or memorized,"they write.Which of the following statements is true of the experiment participants?A:They learned how to control MRL machines in the experiment.B:They were not told what to be learned in the experiment.C:They were paid to take part in the experiment.D:They were not cooperative in the experiment.

Text 1"The love of money",St Paul memorably wrote to his protege Timothy,"is the root of all evil.""All"may be putting it a bit strongly,but dozens of psychological studies have indeed shown that people primed to think about money before an experiment are more likely to lie,cheat and steal during the course of that experiment.Another well-known aphorism,ascribed to Benjamin Franklin,is"time is money".If true,that suggests a syllogism:that the love of time is a root of evil,too.But a paperjust published in Psychological Science by Francesca Gino of Harvard and Cassie Mogilner of the University of Pennsylvania suggests precisely the opposite.Dr Gino and Dr Mogilner asked a group of volunteers to do a scries of what appeared to be aptitude tests.As is ofien the case in such experiments,though,what the voiunteers were told.and what the truth was,were rather different things.In the first test they were asked to make,within three minutes,as many coherent sentences as they could out of a set ofwords they had been presented with.What they were not told was that each of them had been assigned to one of three groups.Some volunteers'word sets were seeded with ones associated with money,such as"dollars","financing"and"spend".Some were seeded with words associated with time（eg,"clock",/'hours","moment"）.And some were seeded with neither.Thus unknowingly primed,the volunteers were ready for the second test.This was mathematical.They were given a sheet of paper with 20 matrices which each contained 12 numbers.two of which added up to ten（for example,3.81 and 6.19）.They had to write down,on a separate answer sheet,how many of these pairs they could manage to find in five minutes.They were also given a packet ofmoney and told they could reward themselves with a dollar for each pair they discovered.This led Dr Gino and Dr Mogilner to suspect that self-reflection played a part in controlling uncthical behaviour during the test.They therefore conducted a third test in which,for half the volunteers,there was a mirror in the cubicle they were sitting in when doing the experiment.Volunteers primed to think about money cheated 39%of the time when a mirror was present but 67%when it was not.Those primed to think about time cheated 32%of the time in the presence of the mirror and 36%in its absence-results that are statistically indistinguishable.Finally,a fourth experiment asked primed volunteers to fill in a questionnaire before tackling the matrix.In among"filler"questions intended to disguise what was happening this asked them to rate how they felt about self-reflective statements like,"Right now,1 am thinking about who I am as a person."As in the previous tests,those primed with money words cheated more ofien than those primed with neutral words and far more ofien than those primed with time words.But whether someone cheated was also related to how strongly he felt about the self-reflective statements presented to him in the questionnaire.It seems,then,that thinking about time has the opposite effect on people from thinking about money.It makes them more honest than normal,rather than less so.Moreover,the more reflective they are,the more honest they become.There must be an aphorism in that.
What can we infer from the tests?A.The subjects have been told their assignment
B.Volunteers who had been primed with money ideas were more likely to cheat others.
C.12%volunteers had been primed with time-related words.
D.33%subjects had been primed with money-related words.
