4．We all know the feeling：looking at the computer screen，pretending to be interested in our homework，even though we really feel bored．But such feelings may soon be at an end，says Dr．Harry Witchel，head of the Essex Medical School．He believes that computers of the future will notice when people feel bored and even take action to stop it．
Before you get concerned，the machine won't be reading your mind．It will be observing the many movements you make while using a computer．It's not interested in the big movements needed to use the machine 一 like moving a mouse or touching a screen-but small，barely noticeable movements like closing your eyes，moving in your seat or rubbing your face．Witchel calls these"boredom movements"and says they show how interested the person is in what they are reading or watching．The higher the interest level，the less movement!
To test his theory，Witchel invited 27 people to perform various computer-based tasks．The activities ranged from playing online games （an interesting task） to reading documents like government laws that most people would find boring．
A special video camera followed the participants'movements as they completed each task．Just as the researcher expected，the"boredom movements"greatly decreased，by as much as 42%，when the subjects were very interested in what they were reading or seeing．
Fortunately，Dr Witchel isn't planning to use his results to create machines that report students who are not paying attention at school．Instead，he wants"movement sensing"technology to be built into future computers in order to improve students'computer-based learning experience．
The scientist says that by measuring the students'interest level as they work，educators will be able to adjust their materials in real-time to keep students focused．Witchel also believes that the technology can provide filmmakers with honest audience opinions and in the future，help to develop more intelligent robots．
32．What does the underlined word"it"in Paragraph 1 refer to？C
A．Homework．B．A computer．C．Boredom．D．The future．
33．Why did Dr Witchel carry out his research？D
A．To discover how bored people move．
B．To find out what makes people bored．
C．To see if interested people are more active．
D．To test the link between boredom and movement．
34．Which movement would Witchel's technology most likely pay attention to？D
A．Turning off the machine．
B．Typing words on a keyboard．
C．Surfing quickly between webpages．
D．Moving one's head from side to side．
35．How will the new technology help education，according to Witchel？B
A．By reducing teachers'workload．
B．By maintaining students'learning interest．
C．By reporting students'misbehavior in class．
D．By making learning more like a computer game．
分析 当我们在利用电脑看书学习时会疲惫，科学家说未来的电脑可以识别人何时疲惫并采取措施．
解答 32．C 33．D 34．D 35．B
32．C 猜测词意题．根据He believes that computers of the future will notice when people feel bored 可知未来的电脑可以知道你什么时候疲惫，并采取措施来阻止疲惫，所以it此处代指前面的 feel bored，故选C．
33．D 推理判断题．根据第二段的介绍可知，Witchel calls these"boredom movements"and says they show how interested the person is in what they are reading or watching．The higher the interest level，the less movement!
Witchel主要想测试boredom和 movements之间的关系，越感兴趣，越不觉得无聊，故选D．
34．D 细节理解题．从第二段可知，but small，barely noticeable movements like closing your eyes，moving in your seat or rubbing your face机器主要注意一些小的，几乎不被注意到的动作，如闭眼、移送座位或者擦脸，所以从移动头也属于这样的小动作，故选D．
35．B 推理判断题．根据最后一段The scientist says that by measuring the students'interest level as they work，educators will be able to adjust their materials in real-time to keep students focused．可知，科学家主要想利用该技术提高学生学习的兴趣，故选B．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
