The mystery of Leonardo da Vinci's famous Mona Lisa painting has been cracked with the help of emotion-recognition software from scientists recently. According to findings which will be published in the New Scientist, a British journal, the exact breakdown of Mona Lisa's emotions,   were 83 percent happy, 9 percent disgusted, 6 percent fearful, and 2 percent angry.

The software rated features such as the curvature (曲度) of the lips and crinkles around the eyes. Dr. Nicu Sebe, a professor at the University of Amsterdam in the Netherlands, used emotion-recognition software to come up with the exact breakdown of Mona Lisa's emotional state.

The program draws on a database of young female faces to get an average "neutral" expression. The software uses this average expression as the standard for comparisons. Other applications of emotion-recognition software might be to detect terror suspects on the basis of their emotions as well as their physical characteristics.

Possibly the most famous portrait of all time, Mona Lisa's mystifying expression has puzzled art lovers for five centuries. In 2003, a scientist from Harvard University said the way the human eye processes visual information meant the smile was only obvious when the viewer looked at other parts of the painting.

The painting, which is on public display in the Louvre in Paris, was painted between 1503--1506．It was thought to be named after the sitter, most likely the Florentine wife of Francesco del Giocondo.

68．Which of the following is probably the practical use of the emotion-recognition of software?

       A．It can be used to decide whether a painting is valuable.

       B．It can be applied to detect a criminal.

       C．It can show the painter of an ancient painting.

       D．It makes Mona Lisa known to the world.

69．The software judges people’s emotion by _____.

       A．the features on their face                            B．the smile on their face

       C．the way they talk                                       D．the painting which has been painted

70．Which statement is true according to the text?

       A．The painter of Mona Lisa had a mixed emotion of happiness, disgust, fear and anger while painting.

       B．Leonardo da Vinci worked out an emotion-recognition software with the help of scientists.

       C．The name of Francesco del Giocondo’s wife could be Mona Lisa.

       D．The painting Mona Lisa was painted in the fifteenth century.
