Not even Dan Brown and his Da Vinci code—breakers(密码破译者)dared deal with the mystery of Mona Lisa,s smile.But Nicu Sebe,a computer expert the University of Amsterdam,the Netherlands,did.He used’emotion recognition’software to process the famous painting and found Mona Lisa happy(83 per cent)and slightly disgusted(厌烦的)(9 per cent).

Faces show emotions. Psychology,computer science,and engineering researchers are joining forces to teach machines to read expressions.If they succeed,your computer may one day“read”your mood.Machines equipped with emotional skills could also be used in teaching,gaming,mind-reading,etc.

“Mind Reader”,a system developed by Rosalind Picard at MIT(the Massachusetts Institute of Tech’nology)in the US, uses input from a video camera to do real—time analysis of facial expressions. It reports on whether you seem“interested”or“agreeable”or if you’re“confused”.The system can help people recognize others’emotions.Picard says this means we could teach a machine to be as sensitive as a human.In fact,a machine can be even smarter than people since it can tell if a person is lying or just“performing”by analyzing one’s facial movements.

Jeffrey Cohn,a psychologist at the University of Pittsburgh,uses the Facial Action Coding System to recognize human emotions.The system sorts more than 40 action units(AUs)of the face to tell people’s real emotions.He studied a videotape of a criminal who said to be sad about the murder of several family members and tried to pin the blame on someone else.But Cohn saw no real sadness in the woman’s face.

Sadness is a group of AUs that is difficult to do at the same time.You have to pull down the woman’s of your lips while bringing your eyebrows together and raising them.What the woman did was raise her cheeks to make a lip cud(撇嘴)。Her brows stayed smooth.

A.Paragraph 2   B.Paragraph 3      C.Paragraph 4     D.Paragraph 5

66.How many facial emotion analyses are mentioned in this passage?

A.Four.               B.Three.              C.Two.         D.One

67.The underlined word“it”refers to________.

A.MIT                                 B.the video camera

C.one’s face emotion            D.the real—time analysis
