She has since used it with her two younger sons Dominic, 8, and Matthew, 3.[來源 :學(xué) 科 網(wǎng) ] Baby sign language is nothing new: the practice (which is based on adult sign laguange) has been out in America for more than 30 years. But it is enjoying a rebirth in New Zealand. The idea behind baby sign language is that babies do have the ability to municate their needs if they are given the right tools to do so. Although many mothers develop an intuition (直覺 ) about whether their baby’s crying is from hunger, tiredness, or pain, baby sign language c reates a direct form of munication that unlocks the mystery. When babies are between 6months and 12 to 13months, parents can begin to teach them sign language: use the sign for milk while feeding, and also talk about milk, so that the child begins to make the link (關(guān)聯(lián) ) in their brain. Then they can begin to add other signs, . food, sick or pain. “I know of one parent. Her child was signing the sign for hurt by his month, and she realized his first teeth were growing. It makes life so much easier,” said Holt. 25． Why did Holt go to the baby sign language workshop? A． To entertain her own children. B． To better understand babies’ needs.

At times, he says, it can be hard to tear himself away from a device (設(shè)備 ), especially when he’s playing NBA General Manager. What makes some video games so attractive? Raph Koster, an expert on game design, says game makers employ a great deal of knowledge about what keeps people playing. He says that whether they know it or not, players like getting feedback (反饋 ) that they can see or hear. The game Peggle, for example, plays the song “Ode to Joy” every time you succeed at beating a level. “It gives you this amazing amount of celebration,” says Koster. Game makers also know that once players have put in the time and effort to achieve a goal, they don’t like to give up. So some games are easy at first and bee more challenging (挑戰(zhàn)性的 ). At that point, the players may be offered a resource (資源 ) that makes winning easier. “The game creates a problem that it offers to solve for you in exchange for cash,” explains Ian Bogost, a professor who studies video games at the Geia Institute of Technology. When players are connected to the Inter, developers can observe what they do. By recording players’ choices, game panies can find out what keeps people interested in and what makes them most likely to buy things. Besides game developers, scientists are also paying attention to the power of games. Adam Gazzaley, a scientist at the University of California, has developed games that improve attention and memory in older adults. Now Gazzaley and his team are designing brainbuilding games for kids. “We think that how video games really pull you in and demand your attention can be used to help improve how the brain process (處理 ) information,” he says. To test the games’ effects on the mind, Gazzaley records brain activity while people play. He says that one day, doctors might advise patients to play video games to improve their intelligence. 29． It’s difficult for Jaden Darnell to ______. A． stop playing games B
