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 當(dāng)我們在利用電腦看書學(xué)習(xí)時(shí)會(huì)疲憊，科學(xué)家說未來的電腦可以識別人何時(shí)疲憊并采取措施．
解答 32．C 33．D 34．D 35．B
32．C 猜測詞意題．根據(jù)He believes that computers of the future will notice when people feel bored 可知未來的電腦可以知道你什么時(shí)候疲憊，并采取措施來阻止疲憊，所以it此處代指前面的 feel bored，故選C．
33．D 推理判斷題．根據(jù)第二段的介紹可知，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主要想測試boredom和 movements之間的關(guān)系，越感興趣，越不覺得無聊，故選D．
34．D 細(xì)節(jié)理解題．從第二段可知，but small，barely noticeable movements like closing your eyes，moving in your seat or rubbing your face機(jī)器主要注意一些小的，幾乎不被注意到的動(dòng)作，如閉眼、移送座位或者擦臉，所以從移動(dòng)頭也屬于這樣的小動(dòng)作，故選D．
35．B 推理判斷題．根據(jù)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，科學(xué)家主要想利用該技術(shù)提高學(xué)生學(xué)習(xí)的興趣，故選B．
點(diǎn)評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
