【题目】 It's common knowledge that the woman in Leonardo da Vinci's most famous painting seems to look back at observers (观察者), following them with her eyes no matter where they stand in the room. But this common knowledge turns out wrong.

A new study finds that the woman in the painting is actually looking out at an angle (角度) that's 15.4 degrees off to the observer's right-well outside of the range that people normally believe when they think someone is looking right at them. In other words, said the study author, Horstmann, "She's not looking at you." This is somewhat ironic, because the entire phenomenon of a person's gaze (凝视) in a photograph or painting seeming to follow the viewer is called the "Mona Lisa effect (效应)". That effect is absolutely real, Horstmann said. If a person is illustrated or photographed looking straight ahead, even people viewing the portrait from an angle will feel they are being looked at. As long as the angle of the person's gaze is no more than about 5 degrees off to either side, the Mona Lisa effect occurs.

This is important for human interaction with on screen characters. If you want someone off to the right side of a room to feel that a person on-screen is looking at him or her, you don't cut the gaze of the character to that side-surprisingly, doing so would make an observer feel like the character isn't looking at anyone in the room at all. Instead, you keep the gaze straight ahead.

Horstmann and his co-author were studying this effect for its application in the creation of artificial-intelligence avatars (虚拟头像) when Horstmann took a long look at the "Mona Lisa" and realized she wasn't looking at him.

To make sure it wasn't just him, the researchers asked 24 people to view images of the "Mona Lisa" on a computer screen. They set a ruler between the viewer and the screen and asked the participants to note which number on the ruler intersected (横切) Mona Lisa's gaze. To calculate (估测) the angle of Mona Lisa's gaze as she looked at the viewer, they moved the ruler farther from or closer to the screen during the study. Consistently, the researchers found, participants judged that the woman in the "Mona Lisa" portrait was not looking straight at them, but slightly off to their right.

So why do people repeat the belief that her eyes seem to follow the viewer? Horstmann isn't sure. It's possible, he said, that people have the desire to be looked at, so they think the woman is looking straight at them. Or maybe the people who first created the term "Mona Lisa effect" just thought it was a cool name.

【1】It is generally believed that the woman in the painting "Mona Lisa"

A.attracts the viewers to look backB.looks at the viewers wherever they stand

C.fixes her eyes on the back of the viewersD.seems mysterious because of her eyes

【2】The purpose of the experiment involving 24 people was to _________.

A.calculate the angle of Mona Lisa's gazeB.create artificial-intelligence avatars

C.make sure Horstmann's belief is rightD.explain how the Mona Lisa effect can be applied

【3】What gaze range in a painting will cause the Mona Lisa effect?

A.B.

C.D.

【4】What can we learn from the passage?

A.Horstmann thinks it's cool to create the term "Mona Lisa effect".

B.The Mona Lisa effect contributes to the creation of artificial intelligence.

C.The position of the ruler in the experiment will influence the viewers' judgement.

D.Feeling being gazed at by Mona Lisa may be caused by the desire for attention.
