Little babies love copying what their parents say. But at some point, they stop just repeating, and begin to make their own sentences. When does this change happen?
A new study showed us that English-speaking kids begin creating their own sentences around 2.5 years old. To do this, they need to learn the rules of the language at first. For example, in English, words like "a/an" and "the" always come before nouns, such as "apple" or "orange".
The scientists did a study among 64 English-speaking kids for ninety minutes every four months. They found that these kids, at about 30 months old, began to use both "a/an" and "the" before the same noun. For example, they might say "a dog" and "the dog" in different sentences. This showed they understood how to use "a/an" and "the". In addition, they used this rule to make new sentences that their parents never said before!
But the scientists couldn't record everything that kids hear and say every day. So they developed an AI model and used it to check their findings. The model acted like a young child, and it learned language patterns from the recordings and guessed which words might come next. One of the scientists said, "▲" The team then watched when the model made its first new sentence. Sure enough, it happened around 30 months old, just in line with the real situation of kids.

答案
11. B 由第二段第一句可知，以英语为
母语的小孩大约2.5岁开始造
句，2.5岁即30个月。故选B。
12. D 第四段第二句句意为“因此他
们搭建了一个AI模型以检验他
们的结论”。故选D。
13. B 由上一句可知，AI模型像小孩
一样，它可以学习录音中的语
言模式，并且预测接下来要说
什么。结合选项可知应填B，
大多数时候，它跟孩子做的事
一样。
14. C 由第四段第三句可知，AI模型
与孩子学句型的方式类似。故
选C。
15. C 通读全文可知，本文主要介绍
了一项关于语言学习的研究。
故选C。

【分析】
这是一篇科普类说明文阅读理解，解题时可以先浏览题干标记关键信息，再带着问题回原文定位对应段落，逐一比对选项和原文内容：
1. 第11题询问说英语的孩子能自主造句的时间，回原文找时间相关表述，注意2.5岁等价于30个月的换算，匹配对应选项；
2. 第12题提问科学家开发AI模型的原因，直接定位到第四段的因果句，找到明确的目的表述即可选出答案；
3. 第13题是句子还原类题型，结合空格前后的语境：前文提到AI模型的设定是模拟幼儿，学习录音里的语言模式、预判后续词汇，后文提到模型生成首个新句子的时间和真实幼儿完全吻合，选出能衔接前后逻辑的选项；
4. 第14题判断关于AI模型的正确描述，逐一比对四个选项和原文内容，排除不符合原文的错误表述；
5. 第15题是主旨大意题，通读全文梳理核心内容，排除偏离核心的选项，确定文章的写作目的。
【解析】
11. 细节理解题：根据原文第二段第一句“English-speaking kids begin creating their own sentences around 2.5 years old”，2.5岁换算为月份是30个月，对应选项B，排除A（3岁）、C（2岁）、D（5岁）的错误时间表述。
12. 细节理解题：根据原文第四段第二句“So they developed an AI model and used it to check their findings”，明确说明开发AI模型的目的是检验他们的研究发现，对应选项D，排除A（造新句子）、B（更好记录孩子的话）、C（检查孩子的句子）的错误表述。
13. 逻辑推理题：空格前介绍AI模型的设定是模拟幼儿，学习录音中的语言模式、预判后续词汇，空格后说明模型生成首个新句子的时间和真实幼儿完全吻合，B选项“大多数时候，它和孩子做的事情是一样的”可以完美衔接前后内容，呼应前文“模型像幼儿”的设定，其余选项均无法和前后文的模型运行逻辑形成顺畅衔接，故选B。
14. 细节理解题：根据原文第四段第三句“The model acted like a young child, and it learned language patterns from the recordings and guessed which words might come next”，可知AI模型的语言学习模式和人类幼儿十分相似，对应选项C；其余选项的表述均和原文内容矛盾或无相关依据，予以排除。
15. 主旨大意题：通读全文可知，文章围绕针对幼儿自主造句能力发展的语言学习相关研究展开，介绍了研究过程、发现以及用AI模型验证结论的环节，核心目的是介绍这项语言学习相关的研究，对应选项C；其余选项均偏离文章核心内容，予以排除。
