2.The days of staring at the computer screen pretending to take an interest in an assignment even though you are bored out of your mind may soon be coming to an end.That's because computers of the future will be able to detect boredom and even react to it in real time.But before you get concerned,the machine is not reading your mind.It is just keeping track of the constant involuntary movements that people exhibit when in front of a computer or even a television.These are not the bigger instrumental actions like moving a mouse or using the remote,but sensitive hardly noticeable movements like scratching.Researcher Witchel says the level of movement directly shows how absorbed the person is in what he/she is reading or watching-the higher the interest level,the less the movement!
To test the theory,Witchel and his team invited 27 people and exposed them to a variety of digital content for three minutes at a time.The activities ranged from playing online games to reading documents like the EU banking regulations that most people would find boring.
A video motion (动作) tracker monitored their movements as they powered through each assignment.Just as the researchers had suspected,the involuntary actions decreased remarkably,by as much as 42%,when the subjects were totally absorbed in what they were reading or seeing.
Fortunately,the scientists are not planning to use the findings to create machines that report students who are not focusing at school.Instead,they believe that applying the motion detecting technology to future computers will help improve the digital learning experience.
The scientists say being able to judge the student's interest level will enable educators to adjust the materials in real time and reengage the student.Witchel also believes that the technology can provide filmmakers with honest audience opinions.

B.They are feeling bored.
C.They are very interested.
D.They are thinking actively.
10.How did the researchers come to the conclusion?D
A.By a followup survey.

D.By observing participants'performance.
11.Which field will detecting technology be applied to?D
A.Agriculture.B.Politics.C.Industry.D.Education.
分析 本文是一篇科教类阅读,属于说明文,主要讲述了盯着计算机屏幕的日子,即使你无聊的想法也可能很快就会结束.这是因为未来的计算机将能够检测到无聊甚至对它做出实时反应.
解答 8.C.细节理解题.根据But before you get concerned,the machine is not reading your mind.It is just keeping track of the constant involuntary movements that people exhibit when in front of a computer or even a television.These are not the bigger instrumental actions like moving a mouse or using the remote,but sensitive hardly noticeable movements like scratching.可知,机器会跟踪人们在电脑前,甚至是电视机上持续不断的不自觉的运动.故选C.
9.B.推理判断题.根据Researcher Witchel says the level of movement directly shows how absorbed the person is in what he/she is reading or watching-the higher the interest level,the less the movement!可以推测出,人们在看电视时高水平的运动可能发生在感到无聊时.故选B.
10.D.细节理解题.根据To test the theory,Witchel and his team invited 27 people and exposed them to a variety of digital content for three minutes at a time.The activities ranged from playing online games to reading documents like the EU banking regulations that most people would find boring.可知,科学家是根据人们的表现来得出结论的.故选D.
11.D.细节理解题.根据The scientists say being able to judge the student's interest level will enable educators to adjust the materials in real time and reengage the student.可知,这项技术会被应用到教育上.故选D.
