If you want to help children develop language and speech skills，UCLA researchers say，listening to what they have to say is just as important as talking to them．

The effect of a conversation between a child and an adult is about six times as great as theeffect of adult speech input alone，the researchers found．"Adults speaking to children helps language develop，but what matters much more is the interaction，"said the study's lead author，Frederick Zimmerman，an associate professor in the School of Public Health at the University of California，Los Angeles．The researchers also found that TV viewing didn't have much of an effect-positively or negatively-as long as it wasn't displacing（取代）conversations between an adult and a child．

The UCLA study included 275families with children between 2months and 48monthsold．They represented a variety of incomes and education．The researchers found that，in an average day，children hear about 13，000spoken words from adults and participated in about 400adult-child conversations a day．

Assessed separately，factors positively associated with language development included each additional 100conversations a day and each 1，000word increase in the number of words spoken by adults and heard by children．When looked at alone，TV was negatively associated with language development．But，when the three factors were analyzed together，the only one that stood out was conversation between adults and children．

"The more a child speaks and interacts with an adult，the better idea a parent has about where the child is，"Zimmerman said．"Although it's mostly done unconsciously（无意识地），parents will provide feedback and correct mistakes．They'll also tailor their speech to the child．Parents can give a child words by talking to them about what they're doing，such as，‘I'm putting on your pajamas now'．But give your child the opportunity to talk，hopefully without the rest of the noise in the environment，"she added．"If parents can carve out（分拆）some conversation time-maybe at bath time or at dinner time-that's a wonderful thing．"

解析

分析本文是一篇科普文．研究发现，父母和孩子之间的交谈对孩子语言的发展至关重要，这种交谈必须是双向的、互动的．

解答71．A．细节理解题．从文章第二段最后一句"The researchers also found that TV viewing didn't have much of an effect-positively or negatively-as long as it wasn't displacing conversations between an adult and a child．"可知，看电视对孩子语言的发展没有多少影响，无论是积极的还是消极的；故选A．

72．C．推理判断题．从文章第二段内容Adults speaking to children helps language develop，but what matters much more is the interaction可知，Zimmerman强调父母跟孩子之间交谈的双向性和互动性才是更重要的；故选C．

73．C．推理判断题．从文章最后一段Parents can give a child words by talking to them about what they're doing，such as，‘I'm putting on your pajamas now'可知，父母应该随时创造跟孩子交谈的机会，时间的选择是非常灵活的；故选C．

74．D．词义理解题．根据句子结构和语境分析They'll also tailor their speech to the child，此处tailor是动词，本义是"量体裁衣"，此处的意思是"不断调整以适应"；故选D．
