| Based on Lamb's Neurocognitive Linguistics, this thesis aims at constructing a cognitive functional model to account for transfer clauses.Neurocognitive Linguistics is one of important linguistic schools originated in USA in 1960's. Lamb creates the relational network to highly formalize linguistic system, holds the view that linguistic system is nothing but a system of relationships, and argues the correspondent relationships between network models and neural facts. With reference to Systemic Functional Grammar, Frame Semantics and Construction Grammar, Cheng Qilong is constructing a cognitive functional model, which develops Lamb's relational network.This thesis adopts three methods-analysis, catalysis and testing to study transfer clauses in this thesis. First, the thesis analyzes transfer clauses to get the conceptual structures, grammatical structures and their realizational relationships. Then the thesis builds a cognitive functional model of transfer clauses according to the result of analysis. The thesis draws relational network graphs to manifest the model. At last, the thesis programs the computer to simulate the relational network and test whether the model is workable or not.The thesis lists what have been found during the process of the above study. First, action structures are conflated with causation structures. Second, when topic choices are different, same conceptual structures are realized in different grammatical structures. Third, for give-type transfer clauses in the material domain and tell-type transfer clauses in the mental domain, their realizational relationships between conceptual structures and grammatical realizations are similar. For get-type transfer clauses and learn-type transfer clauses, their realizational relationships are distinct. Finally, testing proves that the model is supported by language phenomena. The operation process of the model is not incompatible with that of the neural network. Therefore the model is operational.
