12．Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goer's life．
But there may be a benefit to doing so，as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests．
The research found that people who watched a movie in 3D improved cognitive （认知） skills，compared to those who watched it in 2D．
The research was led by neuroscientist（神经学家） Dr Patrick Fagan from Goldsmiths University in London．More than 100people took part in the experiment，where participants watched Disney film Big Hero 6in either standard format or RealD 3D．
They also carried out a brain-training-style test before and after seeing a section from the film．The test covered memory，reaction times and cognitive function and the results were compared later．
According to the research，which was carried out in partnership with science group Thrill Laboratory，participants experienced a 23percent increase in cognitive processing，as well as an 11percent increase in reaction times．
Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain power in the future．
"These findings are more significant than you might think，"he said．"It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life．There has never been a better time to look at ways to improve brain function．The initial results of this study show that 3D films may potentially play a role in slowing this decline．"
A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed heightened （加强的） activity when watching 3D．According to the results，participants were seven percent more engaged with what they were watching，adding to argument that 3D movies are more like watching real-life---something Professor Brendan Walker from Thrill Laboratory agreed with．
"As Professor Brendan Walker's test concluded，3D films are more attractive and heighten the senses---this，in turn，makes the brain run at quicker speeds，"Dr Fagan said．

9．According to the research，people watching a movie in 3DA．
A．have a good exercise for their brain
B．lose their short memory of its plots
C．are willing to pay a high price for tickets
D．react the same way as those watching it in 2D
10．What can be learned from the research？B
A．Watching 2D films limits brain function．
B.3D would be a contributing factor in improving brain power．
C．The test was carried out after the whole film was viewed．
D．The participants took the brain-training-style test once．
11．Paragraph 8is mainly aboutD．
A．the application of 3D．
B．the disadvantages of 2D films．
C．the change in brain function．
D．the significance of the study．
12．The text is most likely to appear inC．

9．There have always been laws against copying other people's ideas．However，when copying was only limited to copying something by hand，problems were solved easily．The solution was always the destruction or removal of the copy．Nowadays，the rise of the Internet has made the issue of intellectual property （知识产权） more complicated．
Almost every bit of information can be cut and pasted（粘贴） with a few clicks of a mouse．Many art forms such as writings，films，and music need new protection to ensure that people do not simply transfer them for free．Online illegal copying has been blamed for a huge reduction in the sales of many records because it is hard to convince people to buy something that they can get for free．Even the ideas behind traditional games，such as Scrabble，have been used without the owners'permission．
Old laws have been struggling to keep up．While music companies have been successful in persuading courts that action should be taken against people who illegally download music，the law is difficult to carry out．Furthermore，intellectual property rights vary widely from country to country，so it's up for debate which laws apply．Finally，there is the fact that many people simply do not see the act as theft（盗窃），since once the work has been digitized there is no clear physical object to steal in the first place．
All of these issues mean that companies involved with intellectual property-ideas or easily digitized information-are fighting desperately to get people to pay for the information they use，rather than paying for an object like a CD that they use．While the companies have sometimes been successful，the practical barriers to full protection seem insurmountable．
Finally，all that concerned parties can do is hope that their few successes scare off others and try to find new ways of making money．

A．They are very expensive．
B．They are impossible to copy．
C．It is easy to make CDs，books，and movies．
D．They are easily able to be transferred when in digital form．
29．Which of the following is NOT mentioned as a problem of carrying out intellectual property rights？
D
A．Laws are not the same in all countries．
B．People do not see copying information as theft．
C．It is very hard to catch people who are breaking the law．
D．Internet service providers do not want to cooperate with the police．
30．The underlined word"insurmountable"in Paragraph 4means"B"
A．extremely expensive B．impossible to overcome
C．against the law D．hard to prove
31．What can be inferred from this passage？B
A．Music and films will be unnecessary in the future．
B．New laws are necessary but difficult to put into practice．
C．The Internet is likely to become more important in the future．
D．Laws are just a way for greedy companies to control their products．
