That is the shared dream of the toy maker Hasbro and scientists at Brown University in Providence, Rhode Island. The researchers received a 3-million-dollar award from the National Science Foundation for the special project. They want to find ways to add artificial intelligence, or AI, to Hasbro's "Joy for All" robot. The cat has already been on sale for several years. Though priced at over 1,000 dollars, it sold quite well. It was meant to act as a "companion" for old people. Now the project is aimed at developing additional abilities for the cat. Researchers at Brown's Humanity Centered Robotics Initiative are working to decide which activities old adults may need the most. They hope to make the cat perform a small number of activities very well. Such activities include finding lost objects and reminding the person to take medicine or to see a doctor. They also want to keep the cost down to just a few hundred dollars. It is an idea that has appealed to Jeanne Elliott. Her 93-year-old mother Mary Derr lives with her in South Kingstown. Derr has dementia (痴呆). The "Joy for All" cat that Elliott bought this year has become a true companion for Derr. The cat stays with Derr and keeps her calm while Elliott is at work. Elliott said a robotic cat that helps her mother to remember to take her medicine and be careful when she walks would be greater. The researchers are trying to learn how the improved cats will complete helpful activities and how they will communicate. They say that they do not want a talking cat, however. Instead they are trying to design a cat that can move its head in a special way to successfully communicate its message. In the end, they hope to create an exchange between humans and the cat in which humans feel the cat needs them. By doing so, the researchers hope they can even help prevent feelings of loneliness and sadness among elderly people. 1.What's the purpose of the project? A.To relieve the pain of the elderly.

C.Each family can afford such a cat in the future. D.Softer. D.The feeling of being needed is vital to the elderly. B Some parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills. Psychologist Susan Levine, an expert on mathematics development in young children at the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition (认知) after controlling for differences in parents' income, education and the amount of parent talk, Levine said. The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age. "The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate (旋转) and translate shapes," Levine said in a statement. The parents were asked to interact with their children as they normally would, and about half of the children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than the parents of girls. The findings were published in the journal Developmental Science. 1.In which aspect do children benefit from puzzle play? A.Building confidence. B.Developing spatial skills. C.Learning self-control. D.Gaining high-tech knowledge. 2.
