This paper discusses the positioning of body part nouns when they appear with a “V+qilai(起來)”verb-tendency construction as an object. There are two possible sequences for them, one is “V+起+O+來” and the other is “把+O+V+起來”.BR First, we analysed why the“V+起來”construction and body part objects cannot take the sequence of “V+起來+O”. Body part nouns have low categoriality, which means they are not autonomous, discourse-salient entities in a discourse in general. According to the information structure rules, if the position of a sentence element is near the end of the sentence, there is a higher possibility for the sentence element to have new and important information. However, the low-categoriality of body part nouns makes it inappropriate to appear at the end of the sentence.BR Then, based on linguistic data, we analysed the factors which affect the selection between “V+起+O+來” and “把+O+V+起來” , and arrived at the following conclusions: BR There are several syntactic, semantic, and pragmatic factors that influence speakers to choose between “V+起+O+來” and “把+O+V+起來”.BR On the syntactic level, since the adverb “dou(都)” means “all” or “even”, the adverb “ye(也)” which means “even” can only be related to a sentence element on the left side of them. If these two words are related to the body part object, then only the “把+O+V+起來” sequence is possible because it is only through this sequence that the body part object can be lifted to the left of them.BR On the semantic level, if the body part object is highly related to the V, then the “V+起+O+來” sequence is preferred. When two elements have a close semantic relationship, they tend to appear together in high frequency. It is a common phenomenon in languages where zero or short coding is preferred for those meanings and functions occurring more frequently, while for those occurring rarely, overt, and long coding is preferred.BR On the pragmatic level, because of the Economical Principle of Language, the rules of information structure, and the Principle of Head Proximity, speakers will prefer to choose the “把+O+V+起來” sequence.BR Aside from the factors mentioned above, due to a trend of the “把+O+V+起來” sequence being used more often in the verb/adjective-tendency construction, speakers will choose this sequence even if there are no obvious syntactic, semantic, or pragmatic factors.
