Question 24 is based on the passage you have just heard.

听力原文

        (22) [Parents often hear that reading to their children is critical for supporting development, and the message is getting through to them.] In fact, in the United States, a little over half of children between the ages of three and five were read to every day in 2007, and 83% of children in that age group in the same country were read to three or more times per week in 2012. This is good news, because reading to young children helps their language and brain development. In fact, (23) [recent research has found that both the quality and quantity of shared book reading in infancy predicted later childhood vocabulary and reading skills.] In other words, the more time parents spend reading, the greater the developmental benefits in their four-year-old children. This is an important finding, but does it matter what books parents read? A new study has investigated this question. It followed infants across the second six months of life, and found that (24) [when parents showed babies books that had faces or objects with specific labels, they learned more.] This is in contrast to books that did not name images or books that had the same label under each image. Books that named different characters also promoted greater learning. So, what does this mean for parents? Not all books are created equal, (25) [so parents need to choose the books they share with their children with great care.] 

24. What kind of books are said to help babies learn more? （文章说哪类书可以帮助婴儿学到更多？）

解析：A。录音后半部分提到，一项新的研究发现，当父母给婴儿展示的书籍上带有特定标注的脸或物体时，他们能学到更多。A项与此相符，Books with specifically labeled images是对录音中books that had faces or objects with specific labels的同义概述，故为正确答案。

错项排除：B项中的pictures of dolls and toys、C项中的describing the lives of animals、D项中的telling very interesting stories在录音中都没有依据，故均可排除。
