I Know Just How Yon Feel Do you feel sad? Happy? Angry? You maythink that the way you show these emotions is unique．Well，think again．Even the expression of the most personal feelings can beclassified，according to Mind Reading，a DVD displaying every possible human emotion．It demonstrates 412 distinct ways in which we feel：the first visual dictionary of the human heart．Attempts to classify expressions began in the mid-1800s，when Darwin divided the emotions into six types-anger，fear，sadness，disgust，surprise andenjoyment．(46)______Every otherfeeling was thought to derive from Darwin&39;s small group．More complex expressions of emotion were probably learned andtherefore more specific to each culture．But now it is believed that many more facial expressions areshared worldwide．(47)______The Mind ReadingDVD is a systematic visual record of these expressions． The project was conceived by aCambridge professor as an aid for people with autism(孤独症)，who have difficulty bothreading and expressing emotions．But it quicklybecame apparent that it had broader uses．Actors and teachers，for example，need to understand a wide range of expressions．The professor and his research team first had to definean“emotion”．(48)______Using thisdefinition，1，512 emotion terms were identified and discussed．This list was eventually reduced to 412，from“afraid”to“wanting”． Once these emotions were defined andclassified，a DVD seemed the clearestand most efficient way to display them．In Mind Reading，each expressionis acted out by six different actors in three seconds．(49)______The explanation for this is simple：we may find it difficult to describe emotions using words，but we instantly recognise one when we see it on someone&39;s face．“It was really clear when the actors had got it right，”says Cathy Collis，who directedthe DVD．“Although they were givensome direction，”says Ms Collis，“the actors were not told which facial muscles they should move．(50)______”For example，when someone feels contempt，you can&39;t say for certain that their eyebrows always go down． Someone who has tried to establishsuch rules is the American，Professor PaulEkman，who has built a database of how the face moves for every emotion．The face can make 43 distinct muscle movements called “actionunits”．These can be combined intomore than 10，000 visible facial shapes．Ekman has written out a pattern of facial muscular movements torepresent each emotion． (46) A．We thought oftrying to describe each emotion，but it wouldhave been almost impossible to make clear rules for this． B．Theseparticular muscles are difficult to control，and few people can do it． C．Research hasalso been done to find out which areas of the brain read emotional expressions． D．They decidedthat it was a mental state that could be preceded by“I feel”or“he looks”or“shesounds”． E．He said thatthe expression of these feelings was universal and recognizable by anyone，from any culture． F．Any othermethod of showing all the 412 emotions，such as words，would have beenfar less effective． (47) A．We
