4) consistent acquisition order. In order to more fully confirm the points mentioned above and we have multiple development models based on the theory of further discussion on learners "BA" acquisition.
4) consistent acquisition order. In order to more fully confirms the above observations, we develop multi-mode theory, further discussion learner "Ba" of the Acquisition.
4) an acquisition order consistent. In order to fully prove the above point of view, we are based on the multidimensional model, further discussion of learners "acquisition of the" ba.
