【正文】 r, you don39。t cut the gaze of the character to that side173。surprisingly, doing so would make an observer feel like the character isn39。t looking at anyone in the room at all. Instead, you keep the gaze straight ahead. Horstmann and his coauthor were studying this effect for its application in the creation of artificialintelligence avatars(虛擬頭像) when Horstmann took a long look at the Mona Lisa and realized she wasn39。t looking at him. To make sure it wasn39。t just him, the researchers asked 24 people to view images of the Mona Lisa on a puter screen. They set a ruler between the viewer and the screen and asked the participants to note which number on the ruler intersected Mona Lisa39。s gaze. To calculate the angle of Mona Lisa39。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 isn39。t sure. It39。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 coined 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 .

Genes in a plant are what determine what type of characteristics it will have. Plant breeders try to create a specific oute of plants and potentially new plant varieties by changing the genes of the plants through breeding, which is making new plants from parents of different varieties or species. Actually, plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is practiced worldwide by individuals such as gardeners and farmers and by professional plant breeders employed by organizations such as government institutions, universities, cropspecific industry associations or research centers. They have crossbred plants to create the new types of plants that are, for example, bigger, stronger, or more attractive. Crossbreeding can take such a long time, however, and it is inaccurate. Now, we can change exact sections of Deoxyribonucleic acid (DNA), so the process is more accurate and faster. But people all over the world are arguing about its benefits and disadvantages. Some people use the technology to produce desired characteristics of plants and animals. Other people are concerned that the genetically engineered plants may harm the environment and worried that they may be dangerous for people to eat. There are many reasons for changing plants in this way. International development agencies believe that breeding new crops is important for ensuring food security by developing new varieties that are higher yielding(高產(chǎn)的), disease resistant, drought tolerant or regionally adapted to different environments and growing conditions. For example, some genetically engineered plants can live through frost or draught. As a result, famers can make more profit because fewer plants will die. Some genetically engineered plants are more nutritious. They have less fat, taste better or stay fresher than nongenetically engineered plants. This will allow people to buy betterquality fruit and vegetables. Some genetically engineered plants can resist natural pests such as viruses or insects. This reduces the amount of chemical needed to kill pests, which is helpful to the environment. However, genetically engineered plants can cause unexpected problems. Genetically engineered plants that resist pests ma
