双宾句中数量词出现得非常频繁。宾语NP1 和NP2 的位置是基础生成的，表示受影响者的NP1 和表示对象的NP2 在深层结构中有着固定的生成位置，在表层结构中呈现的不同位置是由一定原则控制的移位操作形成的；直接宾语和间接宾语前加数量词的能力也有所不同，这可能也取决于两者深层结构中固有的基础位置。

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.
