We analysed both structural and functional aspects of sentences containing the four adverbials “after”, “before”, “because”, and “if” in two dense corpora of parent-child interactions from two British English-acquiring children (2;00–4;07). In comparing mothers’ and children's usage we separate out the effects of frequency, cognitive complexity and pragmatics in explaining the course of acquisition of adverbial sentences. We also compare these usage patterns to stimuli used in a range of experimental studies and show how differences may account for some of the difficulties that children have shown in experiments. In addition, we report descriptive data on various aspects of adverbial sentences that have not yet been studied as a resource for future investigations.

英语母子交互中状语句的结构和交互方面：对两个密集语料库的分析

我们分析了来自两个英国英语学习儿童 (2;00- 4;07)。在比较母亲和孩子的用法时，我们分离出频率、认知复杂性和语用学对解释状语句习得过程的影响。我们还将这些使用模式与一系列实验研究中使用的刺激进行比较，并展示差异如何解释儿童在实验中表现出的一些困难。此外，我们报告了关于状语句子各个方面的描述性数据，这些数据尚未作为未来调查的资源进行研究。
