问题     Adults are getting smarter about bow smart babies are. Not long ago, researchers learned that 4- day-olds could understand【B1】______and subtraction. Now, British research psychologist Graham Schafer has discovered that infants can learn words for uncommon things long before they can speak. He found that 9-month-old infants could be taught, through repeated show-and-tell, to【B2】______the names of objects that were foreign to them, a result that challenges in some ways the received wisdom that,【B3】______learning to identify tilings common to their daily lives, children don’t begin to build vocabulary until well into their second year. "It’s no【B4】______that children learn words, but the words they tend to know are words【B5】______specific situations in the home," explains Schafer. "This is the first demonstration that we can choose what words the children will learn and that they can respond to them with an【B6】______voice giving instructions in an unfamiliar setting."
    Figuring out how humans acquire language may【B7】______why some children learn to read and write later than others, Schafer says, and could lead to better treatments for developmental problems. What’s more, the study of language【B8】______offers direct insight into how humans learn. "Language is a test case for human【B9】______development," says Schafer. But parents eager to teach their infants should take note: Even without being taught new words, a control group【B10】______the other infants within a few months. "This is not about advancing development," he says. "It’s just about what children can do at an earlier age than what educators have often thought."
