1. Introduction

Explored the difficulties in the study of construction grammar, particularly the creativity and conservatism of children in language acquisition, as well as the phenomenon of "partial production paradox". The article analyzes various factors that limit the productivity of constructions, such as syntax, semantics, pragmatics, and cognition, and points out that existing explanations are questioned due to the abundance of counterexamples. Taking English double object verbs as an example, this paper discusses why certain constructions are accepted while others are not, such as the difference in usage between "give" and "explain". Special attention was paid to Goldberg's "Explain Me This Double Object Puzzle" and questioning whether data dominance is an effective explanation. Finally, the article proposes to explore the productivity limitations of English double object constructions from the perspectives of information structure configuration and interaction between construction components.

2. Existing research on the productivity of English double object constructions

In depth exploration of the productivity limitations of English double object constructions, highlighting their importance in the study of construction grammar. The double object construction encodes transfer events in the form of "S+V+O1+O2", where V is the double object verb, O1 is the indirect object, and O2 is the direct object. Researchers have analyzed the limiting factors of productivity from multiple perspectives, including the voluntariness of the subject, the vital characteristics of the receiver, the focus of the direct object, the semantic meaning of "causative movement" in double object verbs, stress positions, morphological phonological features, and etymology. Gropen et al. believe that morphological phonological features are the main reason for restricting specific verbs from entering the double object construction, while Goldberg's explanation based on etymology is unreasonable. Haspelmath et al. analyzed from the perspective of semantic features and believed that the semantic type of a verb determines whether it can enter the double object construction. However, existing research still cannot fully explain the 'double object puzzle'. Goldberg proposed a new explanation of "data first" in 2019, which suggests that certain verbs have a high coverage of case and case usage, leading to the unacceptability of double object constructions. But this explanation has problems, such as violating the principle of "no synonyms" and being difficult to extend to more verbs. At present, further research is needed to reveal the underlying reasons why verbs that meet semantic requirements cannot enter the double object construction.

3. Information structure limitations of English double object constructions

In depth exploration of the limitations of English double object constructions in terms of information structure, it is pointed out that existing research has mainly focused on the double object O1 and O2, while insufficient consideration has been given to the information structure characteristics of the main verb V. The article attempts to comprehensively examine the information structure characteristics of each component in the double object construction, in order to reveal their collaborative and interactive relationships.

4. Conclusion

Explored the productivity issue of English double object constructions, pointing out that information structure configuration and information flow are limiting factors. The double object construction requires a specific information structure configuration, namely "topic+sub topic+new information/focus". Explained the reason why usage such as' explain me this' is not accepted, which is due to insufficient information content of the direct object, resulting in obstruction of information flow. Propose to change the deliberate degree of the direct object so that the verb can enter the double object construction. At the same time, criticism was given to Goldberg's "data first" interpretation, and a new interpretation scheme was proposed to dynamically examine the collaborative interaction of structural components from the perspective of information structure configuration.
