The number-classifiers appear very frequently in the double object sentence. The location of the object NP1 and the NP2 are based on the generation of the object. The NP1 that represents the affected person and the NP2 that represents the object have a fixed generating position in the deep structure, and the different positions in the surface structure are formed by the shift operation controlled by certain principles. Secondly, the probability of adding classifiers before direct object and indirect object is also different, which may also depend on the inherent basic position in the deep structure of the two.
