Research into how parents talk to babies
Researchers at Washington State University used 【R18】______, together with specialised computer programs, to analyse how parents interacted with their babies during a normal day. The study revealed that 【R19】______tended not to modify their ordinary speech patterns when interacting with their babies. According to an idea known as the【R20】______, they may use a more adult type of speech to prepare infants for the language they will hear outside the family home. According to the researchers, hearing baby talk from one parent and ’normal’ language from the other expands the baby’s 【R21】______of types of speech which they can practise.
Meanwhile, another study carried out by scientists from the University of Washington and the University of Connecticut recorded speech and sound using special 【R22】______that the babies were equipped with. When they studied the babies again at age two, they found that those who had heard a lot of baby talk in infancy had a much larger 【R23】______than those who had not.
【R19】
选项
答案fathers/dads
解析 题目：研究表明……在与婴儿互动时，不会倾向于修正自己平时说话的习惯。审题时，空白处后面跟tended not to modify，证明具有主观能动性，即此处应该填一种人，然后去原文中寻找人称代词；文中在描述实验结果时提到，妈妈是会提高声调模仿婴儿讲话的，而爸爸不会，爸爸不会改变自己的音高或说话频率；原文中raise their pitch or fundamental frequency即题干所说的修正平时说话的习惯。因此答案为dads／fathers。
