1．"Does my smile look big in this？"Future fitting-room mirrors in clothing stores could subtly adjust your reflection to make you look─and hence feel─happier，encouraging you to like what you see．
That's the idea behind the Emotion Evoking System developed by Shigeo Yoshida and colleagues at the University of Tokyo in Japan．The system can manipulate，or in other word，control your emotions and personal preferences by presenting you with an image of your own smiling or frowning face．
The principle that physiological changes can drive emotional ones─that laughter comes before happiness，rather than the other way around─is a well-established idea．
The researchers wanted to see if this idea could be used to build a computer system that manipulates how you feel．The system works by presenting the user with a web-camera image of his or her face─as if they were looking in a mirror．The image is then subtly altered with software，turning the corners of the mouth up or down and changing the area around the eyes，so that the person appears to smile or frown （皺眉）．
Without telling them the aim of the study，the team recruited （招募） 21volunteers and asked them to sit in front of the screen while performing an unrelated task．When the task was complete the participants rated how they felt．When the faces on screen appeared to smile，people reported that they felt happier．On the other hand，when the image was given a sad expression，they reported feeling less happy．
Yoshida and his colleagues tested whether manipulating the volunteers'emotional state would influence their preferences．Each person was given a scarf to wear and again presented with the altered webcam image．The volunteers that saw themselves smiling while wearing the scarf were more likely to report that they liked it，and those that saw themselves not smiling were less likely．
The system could be used to manipulate consumers'impressions of products，say the researchers．For example，mirrors in clothing-store fitting rooms could be replaced with screens showing altered reflections．They also suggest people may be more likely to find clothes attractive if they see themselves looking happy while trying them on．
"It's certainly an interesting area，"says Chris Creed at the University of Birmingham，UK．But he notes that using such technology in a shop would be harder than in the lab，because people will use a wide range of expressions．"Attempting to make slight differences to these and ensuring that the reflected image looks believable would be much more challenging，"he says．
Of course，there are also important moral questions surrounding such subtly manipulative technology．"You could argue that if it makes people happy what harm is it doing？"says Creed．"But I can imagine that many people may feel manipulated，uncomfortable and cheated if they found out．"

分析 本文屬于說明文閱讀，作者通過這篇文章向我們介紹了未來服裝店里的試衣間的鏡子可以巧妙的調(diào)整你的影像，讓你看上去很漂亮并且感覺到很開心，從而使你喜歡上你看到的東西，這就是日本東京大學(xué)的繁熊吉田和同事開發(fā)的情緒系統(tǒng)背后的理念，這個系統(tǒng)能通過呈現(xiàn)給你一個你自己的笑臉或者哭臉來控制你的情緒以及個人偏好．
解答 74．A 細(xì)節(jié)理解題，根據(jù)第二段The system can manipulate，or in other word，control your emotions and personal preferences by presenting you with an image of your own smiling or frowning face．可知這個系統(tǒng)是為了觀察一個人的感覺是否可以不自覺地受到影響，故選A．
75．B 細(xì)節(jié)理解題，根據(jù)第四段The system works by presenting the user with a web-camera image of his or her face─as if they were looking in a mirror．The image is then subtly altered with software，turning the corners of the mouth up or down and changing the area around the eyes，so that the person appears to smile or frown （皺眉）．可知網(wǎng)絡(luò)攝像頭的圖象是讓志愿者感覺他們在照鏡子，讓他們相信自己所看到的圖象，然而這個圖象是被修改過的，由此可知這是一種假象，故選B．
76．D 細(xì)節(jié)理解題，根據(jù)第八段But he notes that using such technology in a shop would be harder than in the lab，because people will use a wide range of expressions．"Attempting to make slight differences to these and ensuring that the reflected image looks believable would be much more challenging，"he says．可知克里德指出在商店中很難采用這項技術(shù)是因為人們的表情過于豐富，由此可知這項技術(shù)的局限性是只能處理一些相對簡單的表情，故選D．
77．C 推理判斷題，根據(jù)最后一段"You could argue that if it makes people happy what harm is it doing？"says Creed．"But I can imagine that many people may feel manipulated，uncomfortable and cheated if they found out．"可知克里德提出雖然這項技術(shù)可以使人感到快樂，但是也會讓人產(chǎn)生被操控感，人們會感到不安以及被欺騙，由此可知人們認(rèn)為自由意志高于一切，故選C．
點(diǎn)評 考查學(xué)生的細(xì)節(jié)理解和推理判斷能力．做細(xì)節(jié)理解題時一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確選擇．在做推理判斷題時不要以個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．
