   TV is so often a parent’s good friend, keeping kids happily occupied so the grownups can cook dinner, answer the phone, or take a shower. But, 【C1】______, that electronic babysitter is not an educational aid. According to a recent research, babies who watch TV are more likely to have 【C2】______ cognitive development and language at 14 months, especially if they’re watching programs 【C3】______ for adults and older children. It’s surprising that TV-watching made a difference at such a tender age.
   This new study followed 259 lower-income families in New York, most of whom spoke Spanish as their 【C4】______ language at home. Other studies examining higher-income families have come to the same conclusion: TV watching not only isn’t educational, but it seems to 【C5】______ babies’ development.
   Babies who watched 60 minutes of TV daily had developmental 【C6】______ one-third lower at 14 months than babies who weren’t watching that much TV. The 【C7】______ may be due to the fact that when kids and parents are watching TV, they’re missing out on talking, playing, and interactions that are 【C8】______ to learning and development.
   But what about "good" TV, like Sesame Street? The researchers didn’t find any pluses or minuses when 【C9】______ to non-educational programs designed for small children, like SpongeBob SquarePants. Earlier research by some of the same scientists has found that parents whose children watch non-educational TV programs like SpongeBob SquarePants spend less time reading to their children or teaching them. The latest study of educational TV programs like Sesame Street adds more 【C10】______ to a recommendation from the American Academy of Pediatrics that babies under age 2 should watch no TV at all.
【C4】
选项

解析 空格应填入形容词修饰名词language。本句提到纽约的大部分低收入家庭在家里讲西班牙语，故推测西班牙语是这些人的母语或主要语言，词库形容词中的primary“主要的”符合语境，故选K。
